Description

The invention relates to a machine tool with a workpiece carrier, on which at least one workpiece holder for holding a workpiece is arranged, and with a spindle assembly having at least one machining spindle on which a machining tool for machining a workpiece held by the workpiece carrier can be arranged, wherein the spindle assembly is mounted to a first guide assembly along a first processing axis relative to the workpiece carrier linearly movable and the workpiece carrier is mounted on a workpiece carrier guide assembly along a workpiece carrier adjusting axis transverse to the processing axis linearly movable.

Such a machine tool is for example in DE 10 2015 115 542.7 described. The known machine tool is easy to operate because, for example, the spindle arrangement is arranged on a tool slide, which can be moved out of the working area next to the workpiece carrier. However, only the machining spindles of the spindle arrangement can simultaneously machine the workpieces on the workpiece carrier.

It is therefore the object of the present invention to provide a more effective machine tool.

To achieve the object, it is provided in a machine tool of the type mentioned above that the spindle arrangement mounted along the first machining axis forms a first spindle arrangement arranged on a first machining side of the workpiece carrier and a second spindle arrangement with at least one second machining side of the workpiece carrier opposite to the first machining side a machining spindle, on which a machining tool for machining a workpiece held by the workpiece carrier can be arranged, is mounted linearly movably on a second guide arrangement along a second machining axis relative to the workpiece carrier.

The machining tools are, for example, milling heads, drills, lathe tools or the like. Preferably, the machining tools are suitable for an exciting machining of the workpieces.

It is an advantageous approach that not only a first spindle assembly for machining the workpieces is available, but a second spindle assembly. The spindle arrangement in can approach the workpiece carrier from opposite sides, namely along the first machining axis and the second machining axis, so that they can simultaneously or at short intervals process the workpieces on the workpiece carrier.

A self-contained invention represents the concept explained below, but which can also be implemented in combination with the already mentioned concept with two spindle arrangements. In connection with the introductory features of claim 1, it is expediently provided that the workpiece carrier forms a workpiece module and the spindle arrangement forms a machining module or the workpiece carrier and the spindle arrangement form a base module, and that the spindle arrangement is arranged on a first machining side of the workpiece carrier and at one at least one second processing module is arranged with at least one machining spindle of the first processing side opposite second processing side of the workpiece carrier.

The machine tool can therefore be built modular according to this concept and is suitable for a variety of extensions. The user can therefore expand the machine as needed and thereby add another processing module to the workpiece module or to the base module comprising the workpiece carrier and the spindle arrangement. In this case, for example, a cross-shaped or T-shaped configuration in plan view is possible, wherein, as it were, the heart of the machine tool or the core of the machine tool is formed by the workpiece carrier.

The conception allows a symmetrical structure. Projecting masses are small or absent. The individual components, e.g. The spindle assemblies are easily accessible, which facilitates, for example, the maintenance. The spindle assemblies are arranged horizontally, for example, at the same height, so do not have to be high. This also makes it possible, among other things, for additional components to be provided above the machine tool, for example for testing workpieces, workpiece changes or the like. A portal for loading or unloading the workpiece carrier can thus be arranged, for example, easily above the workpiece carrier, without the machine is particularly high.

The workpiece carrier is, for example, sandwiched between the spindle assemblies. The spindle assemblies can be moved to and away from the workpiece carrier along the respective first and second processing axes. The respective guide arrangement expediently comprises an actuator for adjusting the respective first or second spindle arrangement.

Also, the workpiece carrier is suitably an actuator for adjustment along the workpiece carrier adjusting axis available.

It should be emphasized that, of course, the respective spindle arrangement as a whole, e.g. a spindle carrier having at least two machining spindles as a whole, is movable along the respective first or second machining axis. For example, the spindle arrangement can be arranged on a tool slide guided linearly along the first machining axis or second machining axis and movably mounted. However, it is also possible, even in combination with a spindle carrier which is movable overall along the first or second machining axis, that a respective machining spindle is movable relative to the spindle carrier. Thus, for example, a double feed can be achieved along the first or second machining axis, namely by the spindle carrier as a whole being movable along the first or second machining axis and at least one machining spindle arranged on the spindle carrier additionally being adjustable relative to the spindle carrier along the respective machining axis. Thus, therefore, the feed during the machining of a respective workpiece on the one hand by the spindle carrier or the tool carriage are made, on the other hand, by the relative to the spindle carrier movably mounted machining spindle.

A geometrically advantageous configuration provides that the first machining axis and the second machining axis are aligned with each other. Thus, so to speak, only a single machining axis can be provided, wherein the mobility of the spindle assembly is given in along this single machining axis.

But it is also possible that the first processing axis and the second processing axis are not aligned with each other, but are parallel to each other.

Another approach is that the first machining axis and the second machining axis are not parallel to each other or aligned with each other, but e.g. run at an angle to each other. Thus, for example, the second spindle arrangement could be mounted so as to be movable obliquely relative to the first spindle arrangement.

The first and / or the second machining axis are expediently horizontal axes. But it is also possible that one or both of the machining axis do not run horizontally, for example obliquely to a horizontal or vertical.

Appropriately, it is provided that the workpiece carrier adjusting axis is a vertical axis. Thus, therefore, the workpieces can be moved vertically up and down, for example, for the purpose of positioning in front of the first spindle assembly and / or the second spindle assembly. Furthermore, it is possible that a workpiece changer is arranged above the workpiece carrier, so that the adjustment of the workpiece carrier along the workpiece carrier adjusting axis can also serve to position the workpiece carrier relative to the workpiece changer.

Furthermore, the workpiece carrier can also perform the positioning work with respect to a functional module. By adjusting the workpiece carrier along the workpiece carrier adjusting axis, for example, a functional assembly arranged above the workpiece carrier for performing at least one function on a workpiece arranged on the at least one workpiece holder can be operated. The functional module may be provided, for example, a machining spindle with at least one machining tool and / or a test device for testing or measuring or both of the workpiece, which is arranged on the workpiece carrier, and / or at least one centering device for centering the arranged on the workpiece holder of the workpiece carrier workpiece.

The machine tool is expediently a so-called multi-spindle machine. It is expediently provided that the first spindle arrangement or the second spindle arrangement or both has at least two machining spindles arranged side by side or one above the other in a row direction. For example, two, three or four machining spindles can be arranged next to one another. It is also possible that there are two rows of spindles, i. that for example in a row direction two or more spindles are arranged side by side, for example, are arranged horizontally next to each other and each form a spindle row and that these spindle rows are arranged vertically one above the other. The row-axis directions of the spindle rows suitably run parallel.

In the same way, it is advantageous if a plurality of workpiece holders, for example at least two workpiece holders, are also arranged next to one another or one above the other in a row direction on the workpiece carrier. Thus, therefore, for example, several workpieces can be clamped and processed simultaneously.

The row directions of the workpiece holder and the machining spindles are expediently parallel to one another.

The workpiece carrier expediently comprises a workpiece bar. The workpiece beam is advantageously supported at its longitudinal ends in each case, for example on a rotary bearing arrangement, which will be explained later or at least on a carriage, which is mounted linearly movable on a stand with respect to the workpiece carrier adjusting axis.

It is also possible that the workpiece carrier is rotatably mounted only at a longitudinal end region.

An advantageous measure is when the workpiece carrier is pivotally mounted about a transverse to the workpiece carrier adjusting axis pivot axis. For example, pivot bearings are provided on the aforementioned carriage to rotate the workpiece carrier.

The workpiece carrier could also be designed in the manner of a column which is pivotable about a pivot axis which is parallel to the workpiece carrier adjusting axis or aligned therewith.

An advantageous measure, even if the workpiece holder is not stationary on the workpiece carrier, for example, the workpiece bar, is arranged. For example, the workpiece holder with respect to a workpiece carrier base, for example, the workpiece beam, about a pivot axis pivotally and / or linearly movably mounted along a control axis. This results in respect to the workpiece carrier still another freedom of movement, in which the workpiece holder and thus the workpiece is adjustable relative to the workpiece carrier base. The positioning of the workpiece carrier is thereby additionally facilitated or there is a higher flexibility with respect to the positioning of the workpieces relative to the spindle assemblies or the aforementioned functional assembly, the tool changer and the like.

An advantageous concept provides that the workpiece carrier has a workpiece carrier base with a holder to which the workpiece holder carrier with at least two workpiece holders of a first type or a second workpiece holder carrier with at least two workpiece holders of a second type is releasably attachable. For example, these workpiece holders are designed carrier plate-like or pallet-like. Thus, the workpiece carrier can be easily converted, for example, to hold workpieces of another type or workpieces in another setup. The workpiece holders of the first type and of the second type can therefore in principle also differ in that they are arranged in different orientation to the already mentioned machining axis or adjusting axes on the respective workpiece holder carrier.

An expedient concept provides that the first spindle arrangement and / or the second spindle arrangement is arranged at least one tool turret with at least two machining tools for machining the at least one workpiece, wherein the at least one tool turret rotatable about a turret axis tool carrier for positioning each of a machining tool in a Machining position and a tool drive for rotational driving of the machining tool located in the machining position. The tool turret allows a fast and effective tool change. It is advantageous if a respective spindle arrangement has at least two or more tool turrets, so that the already mentioned multi-spindle machine is realized. For example, the at least one tool turret is arranged on a tool carriage.

The tool turret may, for example, have two or more machining spindles. Particularly preferred is an even concept in which the tool turret e.g. has two, four or eight tools.

The turret axis of the at least one tool turret is expediently oriented obliquely to the first or second machining axis.

The concept with the at least one tool turret or a plurality of tool turrets is particularly suitable for a so-called intermediate machining of workpieces arranged on the workpiece carrier.

The machining spindles a spindle arrangement can be arranged for example on a block-like spindle carrier. Relative to the spindle carrier, one or more machining spindles can be movably mounted, for example movably along the respective machining axis.

An advantageous concept provides that at least one of the spindle arrangements, that is to say the first spindle arrangement or the second spindle arrangement or both, has a spindle carrier which is movably mounted along the respective first or second machining axis. For example, the spindle carrier forms a tool carriage or is movably mounted on a tool carriage. Appropriately, it is provided that the at least one machining spindles, preferably at least two or more machining spindles, is movably mounted relative to the spindle carrier, for example parallel to the first or second machining axis and / or at least one axis transverse to the first or second machining axis. It is expedient, for example, an adjustability with respect to a so-called Z-axis, a Y-axis and an X-axis.

The adjustability of the at least one machining spindle with respect to the spindle carrier or tool carriage is preferably an adjustability with a small stroke or a small path, so that virtually a very fine positioning of the machining spindles with respect to the spindle carrier and / or the workpiece to be machined is possible. The adjustment can be realized for example by so-called micro-adjusting devices.

The machine concept according to the invention also enables efficient removal of chips. Appropriately, it is provided that it has a single chip conveyor, which operates both spindle arrangement in so to speak.

An advantageous measure, for example, represents when the machine tool has a chip conveyor, which extends below the workpiece carrier and on the first and the second processing side each having a catchment area for collecting chips accumulating in the processing times. An outlet or collection area for discharging or collecting the chips is located adjacent to the first or second spindle assembly. So it is advantageous that only a single outlet area or collection area is present, but the chips are collected directly at the two processing times. The collection or removal of chips is thereby facilitated anyway.

A particularly compact concept provides that the chip conveying device extends under the first or the second spindle arrangement, so that the first or second spindle arrangement is arranged between the outlet region and the collecting region assigned to it. Thus, for example, a chip conveying channel runs under the respective first or second spindle arrangement. For example, the chip conveyor channel may be provided on a machine bed or below a machine bed.

An advantageous concept provides that the machine tool has a fine boring spindle or fine machining spindle. The fine machining spindle can be arranged, for example, on the first spindle arrangement and / or the second spindle arrangement. It is expedient, although in this case a multi-spindle arrangement is realized, i. that, for example, at least one of the spindle arrangements has at least two finishing spindles, in particular at least two fine spindles, which are arranged next to one another in a row direction.

For example, it is preferred that the second spindle assembly comprise one or more finishing spindles, while the first spindle assembly, as it were, performs the rough machining, i. corresponding motor spindles, at least one tool turret or the like. Thus, it is possible, for example, that one or more workpieces are preprocessed simultaneously by the first spindle arrangement, for example drilled, while the second spindle arrangement then makes the finer processing subsequently.

With the finishing spindles or the spindle arrangement with the at least one finishing spindle, a particularly favorable and exact bearing, for example a hydrostatic bearing, is possible. Thus, as a result of the spatial separation and functional separation of the two first and second spindle arrangements, one of the spindle arrangements may have a different bearing concept than the other spindle arrangement, so that, for example, one spindle arrangement is mounted hydrostatically, while the other spindle arrangement has storage using at least one rolling bearing, in particular a ball bearing ,

The concept of the machine tool makes it easy to exchange machining tools. For example, a spindle arrangement can be adjusted away from the workpiece carrier so that the processing tools arranged on a front side of the spindle arrangement are easily accessible. The processing tools are then no longer arranged in the working space in front of the workpiece carrier, which also facilitates maintenance by a maintenance staff.

However, an automatic tool change, i. that the machine tool expediently has a tool changing device.

The tool change device may comprise, for example, a chain magazine, a chain conveyor or the like. Furthermore, a tool change robot or the like is conceivable.

A, in particular in connection with the preamble features of claim 1, in itself an independent invention representing concept, which may also represent a development and advantageous embodiment of the above machine tool, expediently provides that the machine tool a tool changing device with a storage area above the Spindle assembly has. Thus, the space above the spindle assembly can be used. It is advantageous if each spindle arrangement is associated with such a tool change device, ie that, for example, above both spindle arrangements a respective storage area of a respective tool changing device is provided.

In such a storage area arranged or even at a storage area of a tool changing device, which is provided for example next to the spindle assembly, it is advantageous if a testing device, for example for a breakage control, the processing tools is present. A cleaning device for cleaning the machining tools can also be advantageously provided at a storage area of the tool changing device or the tool change.

It is advantageous if the chip conveyor extends below the storage area of the tool changing device. The or a catchment area of the chip conveyor is thus provided, for example, below the storage area for the processing tools, so that chips falling from the used processing tools can fall directly into the chip conveyor.

Furthermore, it is expedient if the storage area is designed so that in each case one set of several, for example, at least two, processing tools in a row direction corresponding to the row direction of machining spindles on the spindle assembly can be stored next to each other.

The storage area is also advantageously designed so that the processing tools are in a horizontal position, i. can be stored with its axis of rotation in a horizontal position, so that falling chips from the processing tools can fall down and, for example, do not damage or contaminate hollow shaft cones or other tool holders or tool holders. For example, no tangles of chips are formed. Shanks for hollow shaft taper tool holders do not pollute or less.

Above one or both spindle arrangements, a guide arrangement for guiding a loading carriage of the tool changing device is expediently arranged. The loading carriage includes, for example, one or more tool holders for holding machining tools to be loaded into the spindle assembly or machining tools to be removed from the spindle assembly.

Appropriately, it is provided that the storage area between the guide assembly for the loading carriage and the guide arrangement for the spindle assembly is provided.

The loading carriage is mounted for example on a guide portal. The guide portal is expediently arranged above the spindle arrangement, which operates the tool changer.

A likewise independent invention, in particular with the preamble features of claim one, or advantageous embodiment of the invention is that it has a tool changing device with a loading carriage, which is transverse to the machining axis at least one spindle assembly, in particular parallel to the workpiece carrier adjusting axis, and / or is mounted movably parallel to at least one machining axis of at least one spindle arrangement for positioning tool holders in front of the at least one spindle arrangement for a tool change. The loading carriage may be mounted transversely to the processing axis, for example in a so-called X-direction movable.

A movement parallel to the machining axis of the spindle arrangement serves, for example, for the loading carriage to be able to approach the already mentioned receiving space or storage space or provision space for machining spindles.

A mobility of the loading carriage parallel to the workpiece carrier adjusting axis serves, for example, to move the exchangeable and to be replaced processing tools frontally from above in front of the spindle assembly or move away from the spindle assembly.

A movement of the loading carriage transversely to the machining axis of the spindle arrangement is advantageously used for the loading carriage initially receiving the currently used machining tools from the spindle arrangement on a free tool holder and then moving the tool holder loaded with a machining tool to be loaded by a transverse movement or adjusting movement transverse to the machining axis of the spindle arrangement Position in front of the spindle assembly.

Also for storing used processing tools in the storage area or for receiving not yet used processing tools from the storage area, the transverse movement of the loading carriage is advantageous.

Advantageously, this may be added to the mobility of the spindle assembly. So if, for example, the spindle assembly across the Machining axis and the loading carriage are also movable transversely to the machining axis, these movements can be performed opposite each other, so that the tool change is very fast.

In the same way, the spindle arrangement can also help, so to speak, when the tool is changed, when it is moved along the machining axis for the tool change. Thus, for example, the spindle arrangement can be moved along the machining axis to the machining tools provided by the tool changer or else away from them.

It is expediently provided that the loading carriage has at least two tool holders, namely one for providing a machining tool for replacement in the spindle arrangement and a tool holder for removing or removing a used machining tool from the spindle arrangement.

Preferably, the loading carriage has a series arrangement with a plurality of tool holders, corresponding to the number of machining spindles of the spindle arrangement, which is operated by the tool changer. In this case, it is advantageously provided that two tool holders are assigned to one processing spindle so that the processing tools can be placed in the initially free and unoccupied tool holders by several processing tools, then the processing tools loaded with the processing tools to be loaded are positioned in front of the processing spindles, so that these processing tools can then be placed against the processing spindles Machining spindles can be arranged. For example, the machining spindles then move forward along the machining axis and pick up the machining tools to be loaded.

The aforementioned measure makes it possible to exchange or replace, as it were, whole sets of machining tools at the same time.

In connection with the preamble of claim 1, an independent invention or an advantageous embodiment of the above machine tool is the following: expediently, the machine tool has a tool changing device with a loading slide between a provided by the spindle assembly tool change position and a change of machining tools in the tool changing device provided for the provision of position is movably mounted. For example, a provisioning station outside the machine tool, in particular next to the spindle arrangement, is provided, where an operator can safely exchange machining tools. It is useful if the provisioning space is provided outside a machine cover.

As already mentioned, the loading carriage is advantageously mounted movably along the first machining axis or second machining axis, in any case the machining axis of the spindle arrangement.

It is advantageous if the spindle arrangement is arranged, as it were, between the workpiece carrier and the provisioning station. In particular, a linear adjustability between the spindle arrangement on the one hand and the provision of space in the loading carriage on the other hand is expedient.

An advantageous measure is when the supply space has the height of a machine bed of the respective spindle assembly or slightly protrudes upwards in front of the machine bed of the spindle assembly, which is associated with the tool changing device. The provisioning station is thus ergonomically and conveniently accessible.

An invention which is also independent of itself constitutes with the preamble features of claim 1 a machine tool which has a workpiece carrier supply device for a workpiece holder carrier on which at least one workpiece holder for holding a workpiece is arranged and which on a support carrier base of the workpiece carrier releasably attachable, wherein a guide assembly for guiding a carrying carriage for supporting the workpiece holder carrier extends above the workpiece carrier. The workpiece holder carrier can be easily positioned. The machine is ergonomic and fast. Of course, further, for example two or more workpiece holders can be provided on the workpiece holder carrier, which has already been explained in detail above.

Particularly preferred is a variant thereof, wherein the guide arrangement for the support carriage at least one guide body, for example a rail, a portal or a rail of a portal, on which a carriage of a workpiece changing device for changing workpieces of the workpiece carrier is movably mounted. Thus, therefore, this guide body can be used twice, so to speak, on the one hand for a workpiece change, on the other hand, but also for replacing or changing the workpiece holder carrier.

The following embodiment of a machine tool likewise constitutes an independent invention. The tool turret explained here can also be a component form a machining module and / or be arranged next to the already mentioned workpiece carrier, for example on the first or second machining side .: machine tool with a tool turret, wherein the tool turret rotatable about a turret axis tool carrier for positioning each of a machining tool in a machining position and a tool drive for rotation Driving the located in the processing position machining tool, wherein the turret carrier is rotatably mounted at opposite longitudinal end portions of a respective rotary bearing about the turret axis. The advantage of this concept is that the tool carrier is rotatably mounted on both Längsendbereichen, so supported. Thus, a high precision in the workpiece machining is possible.

The roller-shaped turret carrier, that is, for example, a roller on whose outer circumference a plurality of tool holders for processing tools are arranged, which can be brought into engagement with the tool drive, preferably has a longitudinal shape. The turret carrier is expediently cylindrical.

Advantageously, the tool turret is held on a carriage or held on a carrier, which is mounted linearly movable and / or pivotable with reference to a linear guide and / or a pivot bearing with respect to a machine bed or a machine base of the machine tool. The carriage may be a cross slide, i. that it is movable, for example, relative to the machine base about mutually angled axes, so that the tool turret, in particular the turret carrier, is movable in the direction of a processing axis and transversely thereto.

Conveniently, the carrier or carriage has projecting arms, between which the turret carrier is arranged. For example, the arms are forked or configured. The arms protrude, for example, in the direction of the workpiece carrier.

For example, the tool turret forms part of a processing module, which has already been explained.

The turret axis expediently runs horizontally. The turret axis expediently runs transversely to a feed axis or machining axis along which the tool turret is movably mounted to a workpiece carrier carrying at least one workpiece. For example, the workpiece carrier is a workpiece carrier, which is movably mounted in the direction of a Y-axis or other workpiece carrier adjusting axis.

The turret carrier, that is, for example, the mentioned roller or the mentioned cylinder, expediently has on its outer circumference in the circumferential direction two or more angularly spaced tool holders for processing tools.

Also in series arrangement of two or more processing tools or tool holders for processing tools between the pivot bearings is advantageously possible.

A series arrangement of tool holders arranged next to one another along a row axis is preferred. A distance between the tool holders expediently corresponds to a distance of workpiece holders on the workpiece carrier. Thus, a multi-spindle machining or simultaneous machining of multiple workpieces is possible. It is understood that a combination of tool holders arranged in the circumferential direction and tool holders arranged along a row axis is also possible, so that several, for example at least two, angularly spaced rows of workpiece holders are arranged on the turret carrier in the circumferential direction.

Hereinafter, embodiments of the invention will be explained with reference to the drawing. Show it:

10 a workpiece carrier as further modules or submodules of the aforementioned machine tools,

11 a variant of the machine tool according to the preceding figures, wherein a workpiece carrier and a spindle assembly are shown with a tool turret obliquely from above,

12 a schematic side view and

13 a schematic plan view of a spindle assembly with a cylindrical tool turret.

A machine tool 10 according to 1 has a workpiece module 11 on, on the side of each a processing module 12 . 13 is arranged. Based on the editing modules 12 . 13 can on a workpiece carrier 20 of the workpiece module 11 arranged workpieces W are processed.

The editing modules 12 . 13 and / or the workpiece module 11 can individual control devices 18 . 118 to have. It is also possible that the editing modules 12 . 13 and the workpiece module 11 have at least one common control device. Conveniently, the control devices communicate 18 . 118 together. One of the control devices 18 . 118 also performs the control of the workpiece module 11 or is designed for this purpose. Conveniently, the machine tool 10 an operating device 17 , There, for example, an operator P, the functions of the machine tool 10 control, monitor or influence in any other way.

The workpiece carrier 20 has a workpiece bar 21 on, the at least one, expediently 2 or 4 Werkstückhalteseiten 22 . 23 having. On each workpiece holding side 22 . 23 For example, each 4 workpiece holder 24 intended to hold workpieces W. The workpieces W are exemplified by connecting rods or other engine components, but this is not to be understood as a restriction.

The workpiece bar 21 is for example on pivot bearings 25 rotatably mounted at its respective longitudinal ends about a pivot axis A or axis of rotation A.

The pivot bearings 25 are at sledges 26 arranged, in turn, on guide rails or guide bodies 27 a workpiece carrier guide assembly 28 along a workpiece carrier adjusting axis Y1 are mounted linearly movable. To drive the sled 26 are for example drive motors 29 intended.

The workpiece carrier guide arrangement 28 supports the workpiece bar 21 at its respective longitudinal ends. The workpiece bar 21 extends between the sledges 26 , The workpiece beam continues to extend between uprights 30 that face up in front of a machine bed 32 of the workpiece module 11 protrude.

A rotary drive 31 for pivoting the workpiece bar 21 or turning the workpiece bar 21 with respect to the pivot bearings 25 is indicated only schematically in the drawing.

The workpiece carrier 20 is thus vertically adjustable along the workpiece carrier adjusting axis Y1, so that it the workpieces W with respect to the processing modules 12 . 13 can position. In addition, the workpiece beam can 21 rotate about the pivot axis A to the Werkstückhalteseiten 22 . 24 each to a processing page 14 . 15 to swing, namely to either the editing module 12 or the editing module 13 , Thus, therefore, on the workpiece carrier 20 held workpieces W first for editing by the machining module 12 and then through the editing module 13 be rotated about the pivot axis A, without them with respect to the workpiece carrier 20 in order to be positioned, ie new ones have to be set up. This results in a precise workpiece machining, namely because the workpieces W their respective position with respect to the workpiece carrier 20 , in particular the workpiece beam 21 , retain, if necessary for editing by the editing module 12 or the editing module 13 between the editing pages 14 and 15 be moved back and forth.

The workpiece carrier 20 or the workpiece module 11 is, so to speak, at the center of the machine tool 10 arranged. It should be noted that some of the configurations described below, although two processing modules 12 . 13 explain. But it is quite possible that, for example, only the workpiece module 11 in combination with one of the processing modules 12 or 13 in connection with the chip conveyor or the tool changing device described in detail can be advantageously realized.

Based on the schematic representation in 3 should the similar processing modules in this case 12 . 13 be explained.

The editing modules 12 . 13 have for example spindle arrangements 40 . 140 on, along a first processing axis Z1 and a second processing axis Z2 on each one machine bed 41 . 141 are mounted linearly movable. The spindle arrangements 40 . 140 are for example on tool slides 42 . 142 arranged. The tool slide 42 . 142 are at leadership orders 43 . 143 with respect to the machine bed 41 . 141 linearly stored. The leadership arrangements 43 . 141 include, for example, rails 44 ,

The tool slides 42 . 142 can integrally the spindle arrangements 40 . 140 have or be integral with these.

An advantageous concept provides that on a respective tool slide 42 . 142 , which could also be referred to as a Z-slide, yet another carriage movably mounted transversely to the respective first and second machining axis Z1 and Z2 45 . 145 is movably mounted in the direction of a first adjusting axis X1 and a second adjusting axis X2. It can, for example, rails 52 on the sledge 42 . 142 for the sled 45 . 145 be provided.

Thus, so the spindle assemblies 40 . 140 on the one hand along the machining axis Z1 and Z2 to the workpiece carrier 20 be linearly moved towards and away from this, so that, for example, the feed during workpiece machining of the workpieces W by the Z-slide or tool slide 42 . 142 is done.

In addition, also a mobility transverse to this feed direction Z1, Z2 is possible, so that the spindle assemblies 40 . 140 also transversely to the machining axes Z1 and Z2 along the adjusting axes X1, X2 to a positioning with respect to the workpiece carrier 20 for processing provided and held workpieces W are movable.

The spindle arrangements 40 . 140 each comprise a spindle carrier 46 at which one or more machining spindles 47 are arranged. The machining spindles 47 have on to the edit page 14 . 15 towards the unspecified in the drawing tool holder, where editing tools 48 can be arranged. In the editing tools 48 These are, for example, milling heads, drills, lathe tools or the like.

The machining spindles 47 For example, they may be oriented in a row direction transverse to the machining axis Z1, Z2, in particular parallel to the positioning axis X1, X2.

In the spindle arrangement 140 For example, there are two horizontal spindle rows 150 . 151 arranged vertically one above the other, which are parallel to each other.

By an adjustment of the workpiece carrier 20 along the workpiece carrier adjusting axis Y1, it is possible that on the workpiece carrier 20 arranged workpieces W with respect to the spindle rows 150 and 151 to position. Then the editing tools 48 (in 9 not shown) of the machining spindles 47 work the workpieces W, for example, drill, mill, grind or the like.

The workpiece module 11 and the editing module 12 or the editing module 13 Overall, a basic module 16 form. For example, a basic configuration of the machine tool 10 through the base module 16 in the form of the combination of workpiece module and processing module 12 educated. It is for example possible that the machine bed 32 and the machine bed 41 form a one-piece component or are firmly connected to each other. To this base module 16 can then optionally the editing module 13 be attached or other processing modules, such as a processing module 113 ,

The editing module 113 has a spindle arrangement 240 with tool turrets 148 on.

In the editing module 113 are instead of the machining spindles 47 on the tool turrets 148 arranged machining spindles 147 intended. The tool turrets 148 have, for example, tool carriers 149 on, which are rotatably mounted about a turret axis A3, A4. The turret axes A3, A4 are expediently oblique to the machining axis Z2. The turret axes A3, A4 advantageously not aligned with each other.

The machining axis Z1 and Z2 are parallel to each other. The machining axis Z1 and Z2 are aligned with each other here. The machining axis Z1 and Z2 are, for example, horizontal axes.

Below the spindle arrangements 40 . 140 namely up to the editing pages 14 . 15 towards a chip conveyor extends 55 , The chip conveyor has in the range of editing pages 14 . 15 one catchment area each 57 . 58 for catching chips that are involved in the machining of workpieces W by the spindle assemblies 40 . 140 attack. These chips are from the chip conveyor 55 under the editing module 13 through to an outlet area 56 promoted, where the chips can be collected and / or conveniently removed by an operator or a handling device.

An advantageous concept also provides one or more tool changing devices 60 . 160 in front. The tool changing devices 60 . 160 have storage areas 61 , which are above the spindle arrangements 40 . 140 are located. There, the tool changing facilities 60 . 160 currently not Used editing tools, so for example, change tools 49 , lay down. Thus, the space becomes above the spindle arrangements 40 . 140 optimally used. For example, above the spindle assemblies 40 . 140 one tray each 67 intended. But it can also be provided a storage rack or storage rack, which can bring the further advantage that of the unused exchange tools 49 Lubricant and / or chips directly into the expediently arranged underneath chip conveyor 55 can drip off or fall.

Above the leadership arrangements 43 . 143 or above the spindle assemblies 40 . 140 extends a leadership arrangement 62 . 162 the tool changing facilities 60 . 160 , For example, the guide assemblies include 62 . 162 portals 64 , The portals 64 extend along the machining axis Z1, Z2. For example, the portals have 64 each supports 65 , on which upper side longitudinal rails 66 are stored. At the longitudinal rails 66 is a loading sled 63 . 163 the tool changing facilities 60 . 160 movably mounted.

The loading sled 63 . 163 Thus, it can be moved along a positioning axis Z4, Z5 parallel to the machining axis Z1 or Z2.

A respective loading carriage 63 . 163 further advantageously comprises an X-carriage 71 In any case, a carriage which is movable transversely to the adjusting axis Z4, Z5 horizontally along a control axis X4, X5.

On the sledge 71 is a Y-sleigh 72 , That is, a vertically movable carriage arranged. Thus, on the Y-carriage 72 arranged, not individually visible in the drawing tool holder in a Y-direction, namely in the direction of adjusting axes Y4 and Y5 are moved. So therefore have the loading sleds 63 . 163 Freedom of movement in X-direction, Z-direction and Y-direction, allowing for optimal positioning of machining tools 48 or exchange tools 49 frontal of the spindle arrangements 40 . 140 allows. In this case, the spindle arrangements 40 . 140 due to their mobility through the tool slide 42 and the sledges 45 actively participate in the tool change, for example, by the movements of the spindle assemblies 40 . 140 with the movements of the loading sled 63 . 163 run in a coordinated manner. The spindle arrangements 40 . 41 So can the load sled 63 . 163 to meet, so to speak.

A respective storage area 61 extends below the guide assembly 62 . 162 , Furthermore, the storage areas 61 between the longitudinal rails 66 arranged, leaving the loading carriage 63 . 163 so to speak between the longitudinal rails 66 through unnecessary change tools 49 can take off.

It is a set of change tools 49 positioned next to each other along the X-axis direction. Thus, the loading carriage 63 . 163 a whole set of interchangeable tools 49 record or straight from a spindle assembly 40 . 140 away promoted change tools 49 or editing tools 47 in the storage area 61 lay down. Several sets of exchange tools 49 are arranged along the Z-direction, so for example, the adjusting axes Z4 and Z4, in each case one behind the other.

The leadership arrangements 62 are designed so that the loading sled 63 . 163 Editing tools not only on the one hand between the editing pages 14 . 15 or frontally in front of the spindle arrangements 40 . 140 and on the other hand into the storage area 61 but also beyond editing tools or tools change 49 up to staging areas 69 . 169 can move. There is a provisioning position 68 intended. For example, the deployment position is located 68 above or on a pedestal 70 , There an operator can change tools 50 put down, then the loading sled 63 . 163 pick up and into the respective storage area 61 or directly to the spindle assemblies 40 . 140 bring. The deployment position 68 or the staging areas 169 and 69 are conveniently located outside a machine cover. At any rate, the operator can safely handle the processing tools without him, for example, through the tool slide 42 . 142 or the loading sleds 63 . 163 would be at risk.

Furthermore, it is advantageous if the workpiece bar 21 or at least the workpiece carrier 20 can each be equipped with several differently configured and / or differently arranged workpiece holders simultaneously. For example, it is possible for one operator or several operators to each have a workpiece holder carrier 33 . 133 attach to the workpiece beam or an underlying, not visible in the drawing workpiece carrier base, for example, screw, jam or the like. However, the handling is much easier if, as in the embodiment according to 1 a workpiece carrier supply device 80 is provided. The workpiece carrier supply device 80 includes, for example, a guide arrangement 81 at the one sled 83 is movably mounted. The leadership arrangement 81 includes, for example, a rail 82 which extends transversely to the machining axis Z1, Z2. For example, the sled 83 along the guide 81 along a Axis X3 movably mounted. The sled 83 Can be up to the one place 86 drive, where, for example, different workpiece holder carrier 33 . 133 are stored. A respective workpiece holder carrier 33 . 133 For example, has differently arranged and / or configured workpiece holder 24 on.

The leadership arrangement 81 or the rail 82 includes a portal 85 , The portal 85 has several columns 84 on which the rail 82 is supported. The rail 82 extends into an area above the workpiece carrier 20 so at least the sled 83 and so on the sledge 83 held workpiece holder carrier 33 or 133 up to the workpiece carrier 20 can be moved.

The sled 83 is to be understood by way of example for other embodiments, in which a support device for assisting the operator when changing the workpiece carrier holder 33 . 133 is provided. For example, a manipulator with weight compensation, optionally with motor assistance or the like may be provided. Also a so to speak automatic change of the workpiece holder 33 . 133 is possible without further ado. Even in these cases, the leadership arrangement 81 be used optimally.

The leadership arrangement 81 provides an added benefit in that they also provide a basis for a workpiece changing device 75 represents. For example, on the rail 82 also a sled 76 the workpiece changing device 75 be movably mounted along the adjusting axis X3. In addition, this sled is 76 expediently movable in the Y direction. But this does not necessarily have to be, since the workpiece carrier 20 already in the direction of the workpiece carrier actuating axis Y1 above the workpiece carrier 20 arranged carriage 76 can approach, so this from the workpiece carrier 20 Remove workpieces W and unprocessed workpieces W on the workpiece carrier 20 can arrange.

It is understood that for the workpiece change and the replacement of workpiece holders and different conveyors can be provided. A common leadership arrangement in the nature of the leadership arrangement 81 So represents an advantageous option.

A concept which is likewise advantageous in connection with the above embodiments, but which in itself also represents an independent invention, is disclosed in US Pat 12 and 13 shown.

For example, a processing module has 313 For example, instead of editing modules 13 or 113 can be used, a machine bed 341 , At a top of the machine bed 341 are rails 344 a leadership arrangement 343 arranged. On the rails 344 or at least the leadership arrangement 343 can a tool slide 342 be moved linearly along the machining axis Z1 or Z2. A carriage drive required for this purpose is omitted in the drawing for the sake of simplicity.

At the top of the tool slide 342 is in the direction of the adjusting axis X1 another slide 345 linearly movable. Thus, a kind of cross slide is formed. However, this is only to be understood as an option.

It is possible that the subsequent embodiment of a tool turret, which in turn represents an innovation, is also arranged stationarily with respect to a machine bed of a machine tool.

The sled 345 carries and / or forms a carrier 346 for a tool carrier 350 a tool turret 340 , The tool carrier 350 has a cylindrical or cylindrical shape. At its outer periphery 351 are numerous tool holders 356 provided on each of which a machining tool 348 can be held.

The tool carrier 350 is at its longitudinal end portions each based on a pivot bearing 352 rotatably mounted about a turret axis A2. The turret axis A2 expediently runs parallel to the adjusting axis X2 and / or at right angles transversely to the machining axis Z1. A schematically indicated rotary drive 357 drives the tool carrier 350 to the pivoting movement about the turret axis A2.

Schematically represented is a tool drive 347 for driving a tool holder located frontally in a machining position O, respectively 356 and thus the machining tool held thereon 348 ,

The tool holders 356 are rows, for example in rows 354 . 355 and further, unspecified rows, parallel to the turret axis A2 on the outer circumference of the tool carrier 350 arranged. Thus, for example, four tool holder 356 and therefore also a corresponding number of processing tools 348 be pivoted to the machining position O, in which they through the tool drive 347 are driven. By the processing tools located in each O machining positions 48 Thus, several workpieces W can be processed simultaneously.

The pivot bearings 352 are on in front of the wearer 346 protruding arms 353 intended. The poor 353 stand in the manner of a fork in front of the carrier 346 in front. Between the poor 353 is the tool carrier 350 arranged.

So there is a configuration in which the tool holder 350 in the manner of a drum or a cylinder between the forked arms 353 is rotatably mounted and each of which is located row 354 . 355 or any other row of tool holders 356 to the editing page 14 . 15 or pivots into the machining positions O. The arrow shown in the drawing, the rotational movement or pivotal movement of the tool carrier 350 indicates, pointing only in one direction. Without further ado, a bidirectional rotation in opposite directions of rotation is possible.
