Definitions
- the invention relates to a clamping device and a method for clamping a workpiece between two vices.
- a generic substation is known. This has a first gripping and positioning device arranged at a stationary fastening point for holding a first vice. A second gripping and positioning device for holding a second vice is attached to a robot arm. To reclamp a workpiece between the two vices, the robot provided with the second gripping and positioning device first transports an empty vice to the permanently installed first gripping and positioning device at the stationary fastening point.
- the robot with the second gripping and positioning device picks up the second vice, which is already equipped with a workpiece, and swings it with the workpiece protruding downwards over the empty first vice so that the workpiece can be further processing can be passed from the second vice to the first vice.
- the robot uses the second gripping and positioning device to put down the now empty second vice and can now uncouple the newly loaded first vice from the stationary mounting location and transport it to a processing position in a processing machine for further processing of the workpiece.
- a disadvantage of this re-clamping process is that the accuracy of the positioning of the workpiece in the vice depends on the accuracy of the robot.
- the first vice is arranged at a stationary fastening point during the workpiece transfer and is therefore precisely positioned, but the second vice is held by the robot, so that the placement accuracy is only as accurate as the positioning accuracy of the robot.
- the object of the invention is to create a chucking device and a method for chucking a workpiece between two clamping devices, in which the changeover precision can be improved.
- the clamping device according to the invention for clamping a workpiece between two vices comprises a handling device for positioning and actuating the two vices and a transformer station which contains a carrier for holding a first vise in a precise position.
- the transformer station also has a pressure device with a pressure ram, which can be moved relative to the carrier by means of a drive, for pressing the workpiece against the first vice positioned on the carrier.
- the position of the workpiece when the workpiece is transferred from one screw piece to the other is not determined by the handling device, but by the separate pressure device.
- the pressure ram By means of the pressure ram, the workpiece is pressed precisely against the bearing surfaces of the vice taking over the workpiece, regardless of the positioning accuracy of the handling device, whereby the change position can be significantly improved.
- Another essential advantage of the clamping device according to the invention is that the workpiece is held securely by the pressure device when it is transferred from one vice to the other, even if both vices are open. Even when the clamping jaws of both vices are open, the pressure device holds the workpiece firmly and ensures precise positioning.
- the pressure device can also serve to guide the second vice, which can be moved by the handling device relative to the first vice, when it is moved into the transfer position.
- the vice could, for example, be guided on the pressure device via a side surface of its base body, via coupling elements or a zero-point clamping element arranged on the base body of the vice.
- the guidance can take place passively, in that the handling device holds the vice against a guide geometry on the Pressing device presses.
- the guidance could also take place through active coupling, for example through a form-fitting connection with or without locking.
- the change accuracy can be increased by the contact of the vice with the pressure device. With an active locking, a further improvement of the changing accuracy is possible.
- an aligning and positioning element for connection to the second vice which can be moved by the handling device with respect to the first vice, can be arranged on the pressure device.
- the alignment and positioning element for example designed as a retractable and extendable bolt, can engage in a guide notch or another corresponding counter element on the base body of a vice.
- the positioning can also be carried out encompassing and actively locking, so that the vice can be firmly connected to the pressure device and decoupled from the handling device.
- the pressure ram can contain a grip profile on its side facing the carrier. A particularly secure holding of the workpiece can thereby be achieved.
- the pressure ram can expediently be arranged on a slide that can be moved relative to the carrier.
- the slide can be displaceably guided via a guide carriage and guide rails on a guide plate at right angles to the carrier.
- the pressure ram can be fixedly arranged on the carriage.
- the pressure ram can also be arranged on the slide so that it can be moved.
- the carrier can contain a centering mount and / or positioning elements.
- a measuring system for detecting the workpiece height during reclamping can also be arranged on the pressure device. This can improve process reliability.
- the drive of the pressure device can, for example, be a pneumatic cylinder which contains a piston with a piston rod that can be retracted and extended.
- the invention also relates to a method for clamping a workpiece between two vices, in which a handling device is used to first place a first vice in a carrier of a stationary transformer station and then a second vice by the handling device with a workpiece facing the first vice above the first vice for workpiece transfer is positioned.
- the workpiece is pressed against a support surface on the first vice by a pressure device arranged at the transformer station during the workpiece transfer.
- the vices are preferably rotated by 90 ° relative to one another for workpiece transfer. Due to the offset of the jaw positions in relation to each other, a workpiece can be completely machined on 6 sides in two set-ups. Due to the transformer station with the pressure device, only one handling device is required for re-clamping and transporting the vices.

- the still empty first vice 3a with the jaws 9 and 10 still open is placed on the carrier 15 of the transformer station 5 in such a way that the zero point clamping element 12 protruding from the underside of the base body 8 of the first vice 3a into the centering receptacle 18 of the carrier 15 and the projections 20 on the underside of the base body 5 get into the associated groove-shaped positioning elements 19 on the upper side of the carrier 15.
- the geometry of the centering receptacle 18 is matched to the zero point clamping element 12 in such a way that an exact alignment and positioning takes place during the connection.
- an arrangement of the empty first vice 3a that is accurate in position and secured against rotation is achieved.
- the first vice 3a is only connected to the carrier 15 in a form-fitting manner.
- the vice 3a could also be locked in the carrier 15. Blowing or cleaning bores for supplying blown air could also be arranged on the carrier 15. As a result, chips or other impurities at the contact area between the carrier 15 and the first vice 3a can be removed before the connection.
- the clamping jaws 9 and 10 of the vice 3a are set in the open position by the drive 14 integrated in the gripping and actuating unit 6 via the adjusting spindle 11.
- the data on the required opening width can be transmitted from a process or machine control to the gripping and actuating unit 6. Using this data, the clamping jaws 9 and 10 are adjusted into the required opening position via the adjusting spindle 11.
- a second vice 3b with a workpiece 2 clamped therein and already machined on one side in a position opposite to the first vice 3a, ie with workpiece 2 protruding downward, can be used via the handling device 4, which is uncoupled again from the first vice 3a according to FIG zero point clamping element 12 protruding above can be positioned from above over the still empty first vice 3a in order to transfer the workpiece 2 from the second vice 3b to the first vice 3a.
- the second vice 3b is first brought into contact with the slide 21 of the pressure device 16 via the handling device 4 and then together with the slide 21 in the direction of the carrier 15 moved the first vice 3a.
- the second vice 3b is positioned on the slide 21 of the pressure device 16 so that the pressure ram 17 according to FIG. 5 can reach the opening between the clamping jaws 9 and 10, the base body 5 and the workpiece 2 on the second vice 3b.
- the second vise 3b By placing the second vise 3b on the slide 21, precise alignment of the second vise 3b with respect to the first vise 3a and, in addition, exact guidance of the second vise 3b as it moves in the direction of the first vise 3a can be achieved.
- the second vise 3b is placed on the slide 21 via the bolt-shaped aligning and positioning element 27, which engages in a guide notch on the side surface of the base body 8 of the second vise 3b facing the slide 21.
- the bolt-shaped aligning and positioning element 27 can be extended to different extents via the piston 29, so that vices with base bodies 8 of different widths can be positioned exactly centrally above the vise 3a.
- the second vice 3b can only be guided on the slide 21 of the pressure device 16 via the aligning and positioning element 27 or other coupling elements. However, it can also be guided via other coupling elements arranged on the front or bottom and corresponding counter-elements or actively coupled to the slide 21 and thereby held on it.
- the second vice 3b is moved by the handling device 4 from a positioning position shown in FIG. 3 into a transfer position shown in FIG.
- the slide 21 of the pressure device 16 is also carried along via the pressure ram 17 or the coupling.
- the piston 28 of the drive 25 can be pressureless or only slightly pressurized with compressed air in the extension direction, so that the piston rod only offers a slight resistance to the movement of the slide 21 in the direction of the carrier 15.
- the piston 28 is subjected to pressure in the retraction direction, so that the pressure ram 17 presses the workpiece 2 against a support surface on the first vice 3a, which is still open.
- the support surface can be support surfaces 30 shown in FIG.
- the workpiece 2 is thus securely held between the two still open clamping jaws 9 and 10 of the first vice 3a by the pressure ram 17 pulled over the drive 25 in the direction of the carrier 15.
- the grip profile 26 on the underside of the pressure ram 17 can ensure that the workpiece 2 is also held in a non-slip manner at the side.
- the clamping jaws 9 and 10 of the second vice 3b can then be opened. Due to the arrangement of the pressure ram 17 between the base body 5, the clamping jaws 9 and 10 and the workpiece 2, the second vice 3b is free after the clamping jaws have been opened and can be transported away via the handling device 4. The workpiece 2 then lies in the still open clamping jaws 9 and 10 of the first vice 3a and is fixed by the pressure ram 17.
- the handling device 4 can then move with the gripping and actuating unit 6 to the first vice 3a and close its clamping jaws 9 and 10 after the drive 14 has been coupled to the adjusting spindle 11. Since the pressure ram 17 with its grip profile 26 holds the workpiece 2 precisely and securely even when the clamping jaws 9 and 10 of the first vice 3a are closed, extremely precise positioning of the workpiece 2 within the first vice 3a is achieved.
- the slide 21 with the pressure ram 17 can be moved up to the starting position and the first vice 3a with the clamped workpiece 2 can be returned to the machining process for further machining.
- the workpiece 2 is held by the pressure ram 17, so that a high level of accuracy and process reliability can be achieved during the reclamping.
- the two vices 3a and 3b are preferably rotated through 90 ° relative to one another in the transfer position. As a result, the workpiece 2 can be completely machined on 6 sides in two set-ups.
- a displacement measuring device can be provided on the pressure ram 17, the guide carriage 22, the guide rails 23 or on the drive 25. This allows the workpiece height to be measured during reclamping, thus further increasing process reliability.
- the vise 3a provided for final machining of the workpiece is arranged on the carrier 15 of the stationary transformer station 5 and the second vise 3b holding the already machined workpiece is reversed, ie with the workpiece protruding downwards from above still empty vice 3a positioned for transferring the workpiece.
- the empty vice 3a provided for final machining of the workpiece is arranged at the top and the further vice 3b holding the workpiece that has already been machined is arranged at the bottom.
- a horizontal arrangement with vices lying next to one another would also be possible.
