DE10317344A1 - High-speed clamping cylinder manufacture involves forming casing of high-speed clamping cylinder, inserting functional portions into formed casing, and screwing prefabricated cap to casing to complete high-speed clamping cylinder - Google Patents

Abstract

The method involves separating a cylindrical section from a pipe, and processing the cylindrical section to form the casing (1) of a high-speed clamping cylinder. The functional portions of the clamping cylinder are then inserted into the casing. A prefabricated cap, which is hardened in another processing step, is then screwed to the casing to complete the clamping cylinder. An independent claim is included for the high-speed clamping cylinder.

Description

The The invention relates to a method for producing a quick release cylinder and a quick release cylinder manufactured according to the method the generic term of independent Claims.

With that going back to the same inventor DE 296 15 613 U1 a quick release cylinder has become known, which has an upwardly open housing for receiving the plate springs and which requires a cover which can be placed on the housing. The cover has a central recess in which the piston for the clamping reception of the retractable nipple is arranged so that it is sealed and flush.

The casing was in one piece connected to a floor and was - as described - by one later attachable lid closed from above.

adversely was the elaborate Production of such a quick release cylinder because practical the entire case eroded had to be, which made it extraordinary much chip waste with correspondingly high machining times were incurred.

To improve the above DE 296 15 613 U1 was in the DE 198 34 040 C2 proposed that one forms the housing in one piece with the cover and can therefore mount the entire quick release cylinder from below, because the bottom is now removable.

adversely was here, however, that high machining times are incurred because of the entire manufacture of the quick release cylinder from the open bottom side The entire interior had to be hollowed out had to.

To the manufacture of such a quick release cylinder it was necessary to harden the entire unit. When hardening However, it happened that because of the hollowed-out housing, the lid crowned deformed because of asymmetrical machining due to the asymmetrical Attachment of oil and air inlet holes. Therefore, there were unwanted ones Deformation of the housing after the hardening process (Hardening distortion), what an elaborate Post-processing in the form of subsequent grinding was required.

at the manufacture of the housing The quick release cylinder therefore had to have certain dimensions in excess which are then in the last grinding process Grinding has been removed.

Another Disadvantage was that because of the asymmetrical, pot-shaped housing therefore a delay in hardness happened because the lid had as a support body a different delay property than the pot-shaped side walls of the housing, the pot, which is open at the bottom, bulging in the lid area and contracted in the floor area.

The The invention is therefore based on the object of a method for Manufacture of a quick release cylinder and one according to the process manufactured quick release cylinder so that with essential less effort, shorter machining times and higher accuracy a quick release cylinder can be manufactured.

to solution the task is the method by claim 1 and the quick release cylinder characterized by claim 14.

Important is that for the manufacture of the housing of the quick release cylinder from a tube a cylindrical section is separated, which is taken up in a jaw chuck and if necessary is processed in different places.

In a second process step is a separate one from the tubular housing Lid finished with its own processing tools, and in the next Process step are in the upwardly open tube housing from the functional parts of the quick release cylinder on the cover side used in the next Process step, the lid is screwed to the tube housing and if necessary screwed a cover from the bottom into the tube housing.

With a completely new process is described in the given technical teaching, which is the conventional Procedure is far superior. The essence of the process is that you now make a cylindrical tube housing, which is very easy to edit. It can be any relatively soft material can be used, which works well rotating can be because it is essentially the accuracy required later of the quick release cylinder does not depend on the type and material of the pipe housing arrives, but on the type and accuracy as well as the choice of materials of the lid.

If, according to the invention, the tube housing and the cover are now processed separately and the The fact that the two parts are only brought together at the end has the advantage that the cylindrical tubular housing can be machined very easily. There are very short machining times because it no longer requires the complete hollowing out of a pot-shaped housing, but rather only a cylindrical, tubular part is machined accordingly on a lathe with machining tools. It is sufficient to use a pipe that has a maximum material addition of 1 mm, because the corresponding machining is only carried out in the area of 1 mm depth of the material.

The Manufacturing time of such a cylindrical tube housing in Compared to the previously mentioned pot housing is only about 15% of the time like they used to for the Machining a pot-shaped housing had to be spent.

Another Advantage is - how already executed - that for the tube housing cheap and easy to edit material can be used can because of the service life of the quick release cylinder and the wear resistance determined by the type of processing and the choice of material for the cover becomes.

special The advantage here is that the lid is selected from a hardenable material, which is very simple about a rotating machining can be processed. Even when editing the lid therefore only has short machining times, and here too, only a slight grinding oversize has to be provided.

To the corresponding, high-precision rotating processing of the lid is this hardened, a much lower delay in hardness is accepted must become. The lid itself is a much smaller part, which is an ideal form for hardening has because it has material walls of the same thickness that only little tend to default.

Therefore is also the subsequent one Grinding of this cover reduced to a minimum.

It can at all grinding is not required; instead of grinding, too hard turning takes place, which makes the complex grinding work at all eliminated.

Because the lid is a one-time turned part this part can be turned into one on the lathe Operation with various processing tools and assigned machining steels Process simultaneously, resulting in a short processing time.

Another The advantage is that only a single clamping of the lid is required is, d. H. a reclamping of the lid with corresponding dimensional inaccuracy (Tumbling when reclamping) is not necessary.

advantage of the method according to the invention so that one regarding the choice of material for the cylindrical tube housing and for the lid, which can be machined with high precision, has a free choice of materials. This was not possible with the prior art because the cover was there and the housing made of the same material and in one piece with each other were connected.

earnings of the invention is to have recognized that the accuracy and Low wear of the Quick release cylinder only depends on the material of the cover and that therefore only the lid needs to be machined with high precision while machining of the pipe housing can be much less precise.

Because of these different material selections also have the advantage that the quick release cylinder as a whole in its manufacturing price much cheaper is because only a high-quality cover is combined with an inferior tube housing must become.

Because the lid made of the high-quality material is no longer ground later must be revised, but only in the hard turning process must therefore result in significantly lower manufacturing costs at higher Accuracy.

The Assembly of the quick release cylinder is through the measures according to the invention also significantly simplified, because according to the invention the functional parts of the Quick release cylinders are used, including the bottom floor can be completely eliminated. Instead of a floor, a is preferred Insert module inserted, which the spring assembly between two holding plates clamps. This plug-in module is attached to the inner wall of the pipe housing corresponding locking balls anchored. So a floor can be completely omitted.

Only for the Case that a blow-out housing a floor is added, so that in the space between the plug-in module and the retrofitted floor that over the Compressed air introduced into the interior of the quick release cylinder flows and various blow-out points.

Another advantage of the invention is that the oil is no longer fed into the floor area (after a base is omitted in the main version anyway) and the oil is introduced in the middle of the clamping cylinder at the height of the locking balls, so that a subsequent warping of the pipe housing by introducing the pressure oil no longer has to be accepted.

Because the pressure oil introduced in the space between the piston and the tubular housing will, the housing will only stressed on stretching and no longer on deflection, which is associated with a significantly lower material distortion.

The The subject of the present invention does not arise only from the subject of the individual claims, but also from the combination of the individual claims among themselves.

All in the documentation, including the information and features disclosed in the summary, in particular the spatial training shown in the drawings claimed as essential to the invention, insofar as they are used individually or in Combination versus the state of the art are new.

in the The invention will now be described with reference to only one embodiment illustrative drawings explained. Here go from the drawings and their description essential features and advantages of the invention.

In 1 is shown that from any metal tube, for. B. from an inexpensive steel (St 32), a piece was sawed off, the cylindrical tubular housing 1 represents. This pipe casing 1 forms an outer jacket 2 , an inner jacket 3 as well as two opposite faces 4 . 5 ,

The jaw chuck 6 for example in the direction of the arrow 66 driven in rotation and in the axial direction becomes a machining tool 8th fed which is a steel holder 9 has a series of machining steels on the outer circumference 10-13 are arranged.

With the machining steel 10 will be the bottom end first 4 of the pipe housing 1 scrubbed.

With a machining steel working on the same level 11 becomes this face 4 nachfol enough arbitrated.

With the two machining steels 12 becomes the outer jacket 2 roughed and finished.

With the machining steel 13 is in the outer jacket 2 a circlip groove 14 incorporated.

In the next processing step after 2 is first in the open recess of the tube housing 1 another jaw chuck 17 with its outer cheeks 18 opened, which the tube housing 1 on the outer jacket 2 encompasses, this cheek chuck 17 in the direction of the arrow 15 the pipe housing 1 is fed.

The dimensional accuracy when reaching over the jaw chuck 6 on the jaw chuck 17 It is envisaged that the outer jaws 18 of the chuck 17 a radially inward flare ring 19 train the in the previously installed circlip groove 14 intervenes.

This is a length stop for further processing of the pipe housing 1 given.

Further processing takes place in the sense of 3 where it can be seen that with a machining tool 20 now again different processing steels 21-25 are fed.

With the machining steel 25 becomes the top face 5 of the pipe housing 1 sized. With the machining steels 21 becomes the front 4 roughed and finished.

This is the surface line of the pipe housing 1 well defined.

Because the two opposite machining steels 25 and 21 on the same editing tool 20 are arranged, this also results in the highest possible accuracy, because a delay due to the addition of separate processing tools no longer takes place.

It is also no longer necessary to do a reversal, because it is now in the jaw chuck 17 clamped tube housing is finally machined in this position.

With the machining steel 23 becomes the inner contour of the inner jacket 3 roughed and with the machining steel 22 becomes the inner contour of the inner jacket 3 sized.

With the machining steel 24 became the outer contour of the top face 5 scrubbed.

With the machining steel 23 Incidentally, two punctures flowing into each other are made, namely a ball puncture 34 with a relatively small radius and a subsequent, radially widening puncture 35 for air flow. This is also called an air puncture 35 designated.

With the drill 26 becomes the blow hole 27 for the blown air axially into the tube housing 1 introduced and the core holes for the later threaded holes 29 for fastening the cover using threaded screws.

With the tap 28 the assigned threads in the core holes for the purpose of producing the threaded hole 29 brought in.

With the core drill 30 becomes the core hole for the oil connection 49 manufactured and the hole for the air intake 48 ,

With the drill, the oil connection hole 33 made and with the tap 31 the threads for the air inlet and the oil connection 48 . 49 manufactured.

The 3 shows that the complete tube housing of the quick-action clamping cylinder is finished in a single clamping with all processing steps, without the need for reclamping with a corresponding reclamping error.

All corresponding contours of the surfaces 2 . 5 are manufactured with high precision, with particular reference to the parallelism of the mutually parallel end faces 4 . 5 arrives.

The 4 already shows the last processing steps for the separate production of the cover 40 , This has already been turned, drilled and hardened. He is now in a cheek chuck 36 clamped, the outer cheeks 37 the lid 40 record exciting. For this purpose, the outer jaws 37 a ring gripper pointing in the axial direction 38 on, in an assigned, circumferential groove 67 engages on the lid side of the lid.

It is important that the cover side (that is the surface) is absolutely plane-parallel and a stop surface 39 for the installation of the outer jaws 37 of the chuck 36 forms.

The result is a radially outer contact surface 68 , which is machined with high precision and on which the workpiece pallet will later rest, while the stop surface adjoining radially inwards 39 opposite the contact surface 68 is axially set back and thus free for the support of the workpiece pallet, and radially inwards the stop area 39 a further support surface is formed, which in turn serves to support the workpiece pallet.

This surface is called the inner bearing surface 69 designated.

The workpiece pallet to be placed with high precision therefore only lies on the support surfaces which are spaced apart from one another 68 . 69 on while the stop face 39 for the outer jaws 37 is axially set back.

The 4 shows that the lid can now be finished with a single clamping.

There are a number of editing tools 41 . 42 . 43 . 44 available, which carry at their free ends corresponding machining steels for the hard turning now taking place.

With these different processing tools 41-44 becomes the lid 40 finished with it.

As an example, it is given that, for example, with the processing tool 43 the ring flange 45 finished inside and the complete inner contour including the radially inward nose, which limits the later central receiving opening for the retractable nipple.

It is important that the ball contact surface 70 is highly wear-resistant and machined with high precision.

It is also important that the piston contact surface 71 is also processed with high precision and is wear-resistant.

The lid 40 consists essentially of a disc-shaped cover flange 46 and an axially adjoining ring flange 45 , The two parts are connected to each other in one piece.

Through the central center hole 47 will later be based on the 6 explained nipple 64 retracted.

It is important that the finishing of the lid 40 to 4 takes place in a single clamping and that is why the use of all machining tools 41-44 completely error-free.

The 5 shows only schematically that the previously described and precisely machined surfaces of the lid 40 with the assigned surfaces of the pipe housing 1 interact when the lid 40 with the pipe housing 1 is merged.

Because the outer surface of the pipe housing 1 were machined with great precision, as were the outer surfaces of the cover 40 , the two parts according to 5 can be merged with high precision without surface line errors.

The 6 shows as an example the structure of a quick release cylinder according to the aforementioned method.

In the first step, the tube housing is open at the top and bottom 1 first the plug-in module 50 used. This is in 8th shown in more detail. The plug-in module consists of a lower spring holding plate 53 and from a ball support arranged at a distance from this 52 , The two parts 52 . 53 are by a screw 54 held together and hold the preloaded plate spring assembly between them 51 ,

This plug-in module is now from above 6 in the tube housing 1 inserted and lies on a ball ring 72 firmly in the groove previously described 34 . 35 is inserted.

There are eight balls distributed around the circumference for the ball ring 72 prefers. So this is the plug-in module 50 against falling out of the pipe housing 1 secured down.

Then it becomes the piston 55 from above into the tube housing 1 inserted and then the balls 56 on the upper ball rest 52 of the plug-in module 50 hung up and distributed over the circumference.

Finally, the lid comes after 40 hung up and using the screws 73 screwed.

The 6 shows a quick release cylinder in the blow-out version. If no blow-out were desired, the lid would 57 would be eliminated and the lower bottom end would be due to the spring retaining plate 53 of the plug-in module 50 educated.

However, if the blow-out version is made, then the lid 57 with its central threaded hole on the threaded shaft of the screw 54 screwed on and screwed in until it touches the balls of the spherical ring 72 is applied.

It then results between the spring holding plate 53 and the inside of the lid 57 a gap through which the air flows when it passes through the air connection 62 into the interior of the Schnell clamping cylinder is blown.

This Air is passed through different channels and Cross bores fed to the various blow-off points.

The entire pipe housing 1 of the quick release cylinder is achieved with the help of fastening screws 58 and a ring claw 59 screwed onto a machine table. For this, a circlip 60 used.

Of course, instead of the ring claw 59 also be attached to a processing tower or the like.

As well is the insertion of the quick release cylinder into an assigned one Can be accommodated in the machine table.

In the central recess 61 , the after 7 is shown, then the retractable nipple 64 retracted, which is attached to the underside of a workpiece pallet in a manner not shown.

Via the oil connection 63 the pressure oil is introduced to the piston 55 to drive down and the balls 56 out of engagement with the retractable nipple 64 bring to.

The one on the plug-in module 50 O-ring shown 65 seals the inside of the piston 55 towards the interior of the quick release cylinder and towards the central recess 61 ,

The quick release cylinder according to the invention is therefore characterized in that it has a tubular housing and, separately therefrom, a cover which can be connected to the central tube housing via any releasable connecting means 1 is connectable.

Instead of the screws shown 73 for fastening the cover 40 can of course also other fasteners for attachment to the tube housing 1 be used.

It is also essential that because of the sealing of the central recess 61 compared to the pressure oil, the central recess on the floor side can be kept completely clear, so that either a floor is completely dispensed with or - if a blow-out version is used - only one floor is required 57 from below into the open recess of the pipe housing 1 be screwed in.

The Soil itself takes part in the load transfer no longer part.

In the 9 to 13 an advantageous modification of the method according to the invention is shown, in which all processing steps on the tube housing 1 can be carried out without reclamping or changing the spindle. The fastening claws are made of one piece of material with the tube housing 1 educated. From a metal tube with a correspondingly large wall thickness, e.g. B. from an inexpensive steel (St 32), a piece is sawn off, the cylindrical tubular housing 1 represents. This pipe casing 1 forms an outer jacket 2 , an inner jacket 3 as well as two opposite faces 4 . 5 ,

The tube housing is in a jaw chuck 17 with outer jaws 18 clamped with the jaw chuck in the direction of the arrow 66 is driven in rotation.

How 10 shows, is a machining tool in the axial direction 8th fed which is a steel holder 9 has a series of machining steels on the outer circumference 10-13 are arranged.

With the machining steels 11 and 13 will be the bottom end first 4 of the pipe housing 1 edited, one step 74 is worked out, which later serves as a fastening claw or fastening flange. With the machining steel 12 becomes the inner jacket 3 processed. With the machining steel 10 two interlocking recesses are made, namely a ball recess 34 with a relatively small radius and a subsequent, radially widening puncture 35 for air flow. This is also called an air puncture 35 designated.

The further processing takes place according to the 11 , where it can be seen that the pipe housing with a machining tool 20 different machining steels 21 . 24 are fed.

With the machining steel 21 becomes the top face 5 of the pipe housing 1 processed.

With the drill 26 becomes the blow hole 27 for the blown air axially into the tube housing 1 introduced and the core holes for the later threaded holes 29 for fastening the cover using threaded screws.

With the tap 28 the assigned threads in the core holes for the purpose of producing the threaded hole 29 brought in.

With the core drill 30 becomes the core hole bore for the oil connection 49 manufactured and the hole for the air intake 48 ,

With the drill 32 becomes the oil connection hole 33 made and with the tap 31 the threads for the air inlet and the oil connection 48 . 49 manufactured. With the drill 75 finally the holes in the step serving as a fastening claw 74 brought in.

The 12 and 13 show a section through the completed quick release cylinder in the second embodiment of the invention and the corresponding plan view. The same applies here as already mentioned above in connection with the 6 and 7 has been described, however, a mounting bracket through the step 74 is formed.

The 14 to 18 show a further modification of the method according to the invention. It is the manufacture of a pipe housing 1 for an adapter part 88 a base-side clamping system 89 , Here, the fastening claws are again made of one piece of material with the tubular housing 1 educated. From a metal tube with a correspondingly large wall thickness, e.g. B. from an inexpensive steel (St 32), a piece is sawn off, the cylindrical tubular housing 1 represents. This pipe casing 1 forms an outer jacket 2 , an inner jacket 3 as well as two opposite faces 4 . 5 ,

The tube housing is in a jaw chuck 17 with outer jaws 18 clamped with the jaw chuck in the direction of the arrow 66 is driven in rotation.

How 15 shows, is a machining tool in the axial direction 8th fed which is a steel holder 9 has one or more machining steels on its outer circumference 10 . 11 are arranged.

With the machining steel 10 will be the bottom end first 4 of the pipe housing 1 edited, one step 74 is worked out, which later serves as a fastening claw or fastening flange.

With the machining steel 11 becomes the inner jacket 3 processed.

With a number of other tools 76-84 , such as milling cutters, drills, etc., various bores and recesses etc. are made, as was explained in connection with the above-described embodiments of the invention.

The further processing takes place according to the 16 , with the pipe housing 1 spanned, that is rotated, so that its upper end face 5 points outwards.

The final editing is now done with the editing tools 8th and 20 and other tools, e.g. B. 85 , according to the description of the first embodiment.

With the machining steel 86 becomes a contour 87 for receiving and guiding the balls 56 ( 18 ) worked.

18 shows a section through the assembly of a base-side clamping system 89 with adapter part attached to it 88 ,
