the tool slide path as well as changing the tool slide setting can be carried out.

Is leased from a drive of the type mentioned this object is achieved according to the invention in that the Articulation point arranged on the tool slide and via his stepless adjustment causing actuators direct in different geometric distances with respect to the one lying transversely to the drive direction of the tool slide Edge of the tool slide can be brought.

A further feature of the invention here is that einea sliding block bearing pivot point formed by a pin which is eccentric on one end face of a cylindrical actuator is arranged. that in an eccentric recess of another cylindrical actuator is rotatably mounted, which is also in a cylindrical Recess of a traverse rigidly connected to the tool slide is rotatably mounted, and that both Actuators by means of clamping elements with each other and with the Tool slides can be fixed immovably.

The DT-OS 2 144 · 2o3 is for setting the front position of a tool slide is a horizontal cylindrical recess of the slide - housing rotatably inserted disc provided with an eccentrically arranged cylindrical recess for an inner sleeve which has a square recess, into which the second arm of an angled lever designed as angled lever engages.

However, this sleeve arrangement only serves as a finely adjustable item Transmission link for elements mounted on a shaft after

drive lever engaging in a cam disk, ie a drive of a different kind. In addition, the adjustment range is very narrow because the inner sleeve is not only in the adjusting device of the slide, but also moved transversely to it and therefore only that in the transverse direction existing play between the sleeve and drive lever can be used for the adjustment. All drive and adjustment parts also cooperate there with play during operation, so that the rigidity of the drive is insufficient.

In contrast, the one designed according to the invention is distinguished Tool slide drive is characterized by its particular rigidity, as this is the first direct power transmission between the backdrop love and the tool slide has been achieved without further drive and / or adjustment parts with play "being arranged between them are.

The adjustable arrangement of the two each representing an eccentric Actuators of the setting device enable both a change in position of the in a very simple V / eise Link block in the link lever when the slide is stationary, so a path adjustment, as well as an adjustment of the Slide position, without changing the position of the sliding block, as well as a combination of both setting options.

Setting up and retooling the machine only takes a little time, as there is only one common slide per tool slide Adjusting device is to be adjusted. As a result of the short drive-in and set-up times, smaller batch sizes can also be used Machines that are available on request, especially multi-spindle automatic lathes, are manufactured more economically will. . _c

The drive is inexpensive "and, above all, it saves space, so that in addition to the economic advantages, there are also parts of the gate with regard to an optimal use of space.

Further features of the invention emerge from the subclaims ··

The advantages of these features can be seen in the fact that both actuators are made from disks with ease and accuracy manufacturing circular recesses exist, the ring-shaped Have clamping surfaces. This design of the actuators enables a very simple but effective blocking, which is significantly improved compared to known designs for setting adjustments, since the Elemaflachen have no interruptions. The axially parallel arrangement of the actuators makes the slide drive shaft de ·? The entire setting range, which is only limited by the size of the two eccentrics, can be used.

Furthermore, the for. State of the art adjustment devices for the tool slide position always following the adjustment also the stop or the Stop screw must be readjusted accordingly. For example, was a slide moved further forward and the setter forgot to correct the stop or the stop screw accordingly, there was breakage in the drive to be expected. On the other hand, bein, according to the invention a For all adjustment work, always drive the stop screw at the fixed stop and when the clamping is released the adjustment device is used to adjust the slide position by turning the axially fixed stop screw.

Also, the inventive arrangement of the drive lever and of the link lever on the slide drive shaft is and saves costs and increases the accuracy of the drive.

The invention is described in the drawing using an illustrated embodiment.

which correspond to the depressions 9a of the bore 9, are axially immovable but rotatable in the bore 9 against each other at the remote points so that the inner end faces do not touch each other. Both disks 1o and 11 point eccentrically to the center of the disk arranged unilaterally stepped bores 1oa, 11a, the in the assembled state together an essentially cylindrical Pick up part 12 coaxially and rotatably. A relative rotation of the disks 1o and 11 against each other can not. The two disks Io and 11 thus jointly form a first actuator of the setting device while the part 12 forms the second actuator. The outer contour of the actuator 12. is also Deposed according to the contour of the hole receiving them, whereby a one-sided axial support against the slice Io is achieved. The other side is axially fixed by a clamping washer 13 »in the stepped Part 11a of the bore arranged in the disc 11 and with a clamping member in the form of a screw 14 on the second actuator 12 is releasably attached. The second actuator 12 is also eccentric to the axis of rotation arranged pin 12a, on which the sliding block 5 sliding in the link lever 4 is mounted.

As can be seen from Figure 2, the mutually facing inner end faces of the disks 1o touch and 11, as well as the end faces of the part 12 and the clamping washer 13 by tightening the screw 14 is a twist-proof blocking of all in the tool slide lower part 6 arranged parts 1o, 11, 12, 13 with respect to the tool slide 1 secured. In this state you can controlled by the curve 2a pivoting movement of the drive lever 2 directly into a back and forth movement of the Tool slide 1 are transferred.

The front end position of the Verkzeugschlittens 1 is with Determined using a stop device in "known manner". For this purpose, the tool slide 1 has a stop 15, in which a stop screw 16 is axially adjustable in a mating thread, which is in the front end position of the tool slide 1 on the stationary stop 17 to the plant comes. The other end of the stop screw 16 is in a passage hole of a stationary locking block 18 guided axially displaceably and can be set up by inserting a locking pin 19 in a transverse bore of the Locking block 18 can also be fixed axially immovable. This is only in the foremost end position of the tool slide 1 possible, in which case the stop screw 16 on the one hand at the stop 17 and on the other hand in the locking block 18 is axially immovable. In this state, the Adjustments made.

The adjustment of the Schiittanweges takes place after loosening the screw 14 by turning the sliding block ? bearing actuator 12 relative to the discs 1o and 11 while simultaneously jointly rotating the discs 6. In the carriage base 1o and 11 This is a stepless adjustment of the sliding block 5 i- ⁿ rocker arm 4 achieved without the rocker arm 4 or the tool carriage 1 change their position to one another . At the end of the adjustment process, by tightening the screw 14, the sliding block 5 is again fixed in place in relation to the tool slide 1 and the axial fixing of the stop screw 16 is released by removing the locking pin 19.

The adjustment variable is given with a corresponding scale tunable, which, however, is not shown in the drawing for the sake of clarity, through a bore 2o in the disk 11 it is only indicated that tools for rotating the actuators 1o, 11 and 12 are attached to the ground

can, although other solutions are also conceivable. For example, the bores 2o can be designed as a hexagon socket so that the tool provided for operating the screw 14 can also be used for adjustment. Since only very small adjustment forces have to be applied, is a particularly simple solution is also possible in such a way that outwardly projecting bolts are arranged in the bores 2o that are operated by hand, i.e. without tools.

When changing the tool slide position, the same procedure is initially followed until the screw 14 is loosened as when setting the slide path, in which case the two actuators 1o, 11 and 12 are freely movable, while the stop screw 16 between the stop 1? and the locking pin 19 is axially fixed. Will now be with a If the stop screw 16 is rotated using a suitable tool, the adjusting force acts via the mating thread in the stop block 15 on the tool slide 1, which is thus in a new position is moved. The movement of the slide is controlled by the freely movable actuators Io, 11 and 12 transfer.

If the actuators are now clamped again by the screw 14 and the locking pin 19 is removed, then the starts Tool slide from the desired new position. Since with this setting the new slide position also the sliding block 5 in. the! Tut of the sliding lever 4 can move, so a change in the carriage path is also possible with the position setting, so that after setting a new slide position, the slide path can be adjusted as described. At the end of the adjustment process the screw 14 tightened again and the locking pin 19

removed, in this locking pin 19 are for safety reasons Shear points are designed so that damage to the drive is avoided if this locking pin is removed 19 should be forgotten.

As can be seen from the above, the greatest advantage of the link adjustment described is that with the same means that are used to adjust the setting, without additional attachments, including the tool slide Position can be changed.
