[0005] This utility model provides a multi-station fixture, including a frame, an upper plate disposed on the upper part of the frame, and a bottom plate disposed on the bottom of the frame. It includes a jaw seat, a jaw positioning plate, a guide block, a first pull plate, a second pull plate, a pull block, and a lifting mechanism. The upper plate has a first slot and a second slot. The jaw positioning plate includes a first positioning plate and a second positioning plate. Pull blocks are bolted to both ends of the second pull plate, and the pull blocks are bolted to the first pull plate. The jaw positioning plates are bolted to both ends of the first pull plate. First sliding grooves are formed on both the first and second positioning plates. The guide block slides within the first sliding groove and is bolted to the jaw seat. A protrusion at the lower part of the jaw seat passes through the first slot and is bolted to the jaw seat guide plate. The first positioning plate and the second positioning plate pass through the second slot and are disposed within the groove of the jaw seat. The lifting mechanism drives the second pull plate to move up and down.

[0006] The technical effects of the multi-station fixture provided by this utility model are as follows: By setting a jaw seat, it is convenient to clamp the workpiece. By setting a first sliding groove on the jaw positioning plate and setting a guide block in the first sliding groove, it is convenient for the second pull plate and the first pull plate connected to the second pull plate to move up and down under the drive of the lifting mechanism, thereby driving the jaw positioning plate to move up and down. It is convenient for the guide block to slide up and down in the first sliding groove. Since the jaw seat and the guide block are connected by bolts, the jaw seat clamps and releases the workpiece while the guide block moves. Furthermore, the first pull plate can simultaneously control four sets of jaw seats to clamp the workpiece, thereby improving work efficiency.

[0007] Based on the above technical solution, the multi-station fixture of this utility model can be further improved as follows:

[0008] Furthermore, the first slide is arranged in the shape of a parallelogram and is inclined from top to bottom.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the first groove on the first positioning plate and the second positioning plate is set in an inward V-shape, which facilitates the clamping of the workpiece by driving the jaw seat through the guide block.

[0010] Furthermore, the guide block is arranged in a rhombus shape, and the side length of the guide block is equal to the short side length of the first groove.

[0011] Furthermore, the lifting mechanism includes a motor, a connecting block, a first slider, a second slider, a connecting plate, and a reduction gear. The reduction gear is fixedly installed on the bottom of the base plate, and the motor is fixedly installed on the reduction gear.

The first slider is fixedly connected to the connecting block, and the first slider slides within the second sliding groove.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the lifting mechanism facilitates the movement of the second slider on the fourth slide groove by the motor drive, thereby driving the connecting plate to move back and forth. Since the second slide groove is provided on the connecting plate and the second slide groove is inclined, it is convenient for the first slider to slide in the second slide groove when the connecting plate moves back and forth, which facilitates the up and down movement of the connecting block.

[0013] Furthermore, the second slide groove is inclined, the first slider is parallelogram-shaped, and the first slider is adapted to the second slide groove.

[0014] Furthermore, a third slide groove and a fourth slide groove are provided on the speed reducer frame, the connecting block slides on the third slide groove, and the connecting plate slides on the fourth slide groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the third slide groove facilitates the vertical movement of the connecting block, and the fourth slide groove facilitates the back-and-forth movement of the connecting plate driven by the motor.

[0016] Furthermore, both the first slot and the second slot are provided in multiples, with a second slot provided between every two first slots.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting the first slot, it is convenient for the protrusion of the jaw seat to be inserted and connected to the jaw seat guide plate, which facilitates the fixing of the jaw seat to prevent the jaw seat from shaking, and also facilitates the jaw seat to move laterally on the upper plate to clamp and release the workpiece.

[0018] Furthermore, jaw seat guide plates are provided on both sides of the first positioning plate and the second positioning plate, and the protrusion passes through the first slot and is bolted to the jaw seat guide plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting a jaw seat guide plate, it is easier to maintain stability during the movement of the jaw seat.

[0020] Compared with the prior art, the beneficial effects of the multi-station fixture provided by this utility model are:

[0021] The lifting mechanism facilitates the movement of the second slider on the fourth slide groove by the motor drive, thereby driving the connecting plate to move back and forth. Since the second slide groove is provided on the connecting plate and the second slide groove is inclined, the first slider can slide in the second slide groove when the connecting plate moves back and forth, which facilitates the up and down movement of the connecting block.

[0022] By using the first sliding groove that is inclined on the jaw positioning plate, the guide block slides up and down in the first sliding groove under the drive of the lifting mechanism, which facilitates the jaw seat connected to the guide block to move back and forth on the upper plate to clamp and release the tool.

[0023] By setting a first pull plate and a second pull plate, multiple jaw seats can be controlled simultaneously by a single motor to clamp the workpiece, thereby improving work efficiency. Attached Figure Description

[0040] like Figure 1-8 As shown, this utility model provides a multi-station fixture, including a frame, an upper plate 1 disposed on the upper part of the frame, and a bottom plate 2 disposed on the bottom of the frame. It includes a jaw seat 10, a jaw positioning plate 20, a guide block 30, a first pull plate 41, a second pull plate 42, a pull block 50, and a lifting mechanism. The upper plate 1 has multiple first slots 11 and second slots 12, with a second slot 12 positioned between every two first slots 11.

[0041] The jaw positioning plate 20 includes a first positioning plate 21 and a second positioning plate 22. Pull blocks 50 are bolted to both ends of a second pull plate 42. Pull blocks 50 are bolted to the first pull plate 41. The jaw positioning plates 20 are bolted to both ends of the first pull plate 41. The first positioning plate 21 and the second positioning plate 22 are both provided with inclined first sliding grooves 31. Guide blocks 30 are bolted to jaw seats 10. Guide blocks 30 slide in the first sliding grooves 31. Since the first sliding grooves 31 are inclined, it is convenient to drive the jaw seats 10 to move back and forth on the upper plate 1 when the guide blocks 30 move. The protrusion at the bottom of the jaw seats 10 passes through the first slot 11 and is bolted to the jaw seat guide plate 90 to ensure the stability of the jaw seats 10 when moving back and forth on the upper plate 1. The first positioning plate 21 and the second positioning plate 22 are respectively set in the groove of the jaw seats 10 through the second slot 12. Driven by the lifting mechanism, the first positioning plate 21 and the second positioning plate 22 move back and forth in the groove through the second slot 12.

[0042] The lifting mechanism includes a motor, a connecting block 60, a first slider 61, a second slider 70, a connecting plate 71, and a reduction gear 80. The reduction gear 80 is fixedly installed on the bottom of the base plate 2, and the motor is fixedly installed on the reduction gear 80. A third slide groove 81 and a fourth slide groove 82 are provided on the reduction gear 80. Driven by the motor, the extension end of the motor drives the second slider 70 and the connecting plate 71 fixedly connected to the second slider 70 to move on the fourth slide groove 82. A second slide groove 711 with an inclined arrangement is provided on the connecting plate 71. The first slider 61 is fixedly connected to the connecting block 60. The first slider 61 slides on the second slide groove 711, causing the connecting block 60 to slide on the third slide groove 81, thereby driving the connecting block 60 to move up and down. One end of the connecting block 60 is connected to the second pull plate 42 by bolts, thereby driving the connecting block 60 to move up and down the second pull plate 42. The first slider 61 is arranged in a parallelogram shape to facilitate the first slider 61 to fit with the second slide groove 711 and slide within the second slide groove 711.

[0043] In use, the drive motor drives the connecting plate 71 to retract, and the first slider 61 on the connecting block 60 slides on the second slide groove 711, causing the connecting block 60 to rise along with the first slider 61. The rising of the connecting block 60 causes the second pull plate 42 to rise, and the rising of the second pull plate 42 causes the first pull plate 41 and the jaw positioning plate 20 connected to the first pull plate 41 to move upward. When the jaw positioning plate 20 moves upward, since the first positioning plate 21 and the second positioning plate 22 both have first slide grooves 31, the guide block 30 in the first slide groove 31 slides downward on the first slide groove 31, thereby causing the first positioning plate 21 and the second... The jaw seats 10 on the positioning plate 22, which are respectively connected to the guide block 30, move to both sides. After the workpiece is placed between the two jaw seats 10, the drive motor drives the second slider 70 to extend, which in turn drives the first slider 61 to slide downward, thereby causing the connecting block 60 to move downward. The downward movement of the connecting block 60 drives the second pull plate 42 and the first pull plate 41, which is bolted to both ends of the second pull plate 42 by the pull block 50, to move downward. This causes the guide block 30 to slide upward in the first slide groove 31, which in turn causes the jaw seats 10 on the first positioning plate 21 and the second positioning plate 22, which are bolted to the guide block 30, to move inward and clamp the workpiece.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
