[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-station clamping vise adopts a novel structural design, the specific details of which are as follows:

[0018] (1) In the process of using the multi-station clamping vise, the vise mounting plate is placed on the top of the mounting base, and the two adjacent first threaded holes are put together. The vise mounting plate is fixed on the top of the mounting base by the first bolt. The connecting block is engaged in the inner side of the connecting groove, and with the action of the second bolt and the second threaded hole, the connecting block is fixedly installed with the vise mounting plate. This makes the mounting base, vise mounting plate and connecting block set as independent modules, reducing the difficulty of manufacturing the parts of the device. Worn or damaged parts can be disassembled and replaced separately, reducing downtime and maintenance costs.

[0019] Furthermore, by adjusting the component settings, the device can adjust the position of the first clamping plates on both sides, thereby clamping and limiting the workpiece to be processed, which facilitates subsequent processing.

[0020] (2) The multi-station clamping vise is rotated by rotating the adjusting blocks on both sides during use. The adjusting blocks drive the threaded rod to rotate. Through the threaded connection with the first clamping plate, the first clamping plate slides back and forth in the groove opened on the top of the mounting base to clamp and limit the workpiece to be processed. The sliding block slides in the sliding port to increase the stability of the first clamping plate during movement and increase its clamping effect.

[0021] Furthermore, the addition of a second clamping plate and a third bolt enhances the device's clamping capabilities to accommodate diverse workpiece clamping needs.

[0022] (3) In the process of using the multi-station clamping vise, the second clamping plate is engaged in the inner side of the slot. The second clamping plate is fixedly installed inside the first clamping plate through the threaded connection of the third bolt and the third threaded hole. This makes it easy for the staff to quickly change the second clamping plate of different specifications to meet the diverse workpiece clamping needs. This ensures the clamping effect while taking into account practicality and economy.

[0023] (4) After the material is clamped, the multi-station clamping vise can start the motor when the mounting base needs to be rotated during the operation. The motor drives the auxiliary plate to rotate, which can not only adjust the angle according to the actual situation, making it convenient for the operator to operate, but also discharge the debris during the processing through centrifugal force. After the debris is discharged, it will fall onto the guide plate and the working plate and be collected by the operator.

[0024] Furthermore, as the auxiliary plate rotates, the support column and the ball bearings play a role in stabilizing the auxiliary plate. At the same time, the rotation of the support column intermittently pushes the inner rod, and the inner rod and the movable plate, under the action of thrust, guide plate and auxiliary spring, make reciprocating linear motion in the horizontal direction. In turn, the movable plate intermittently hits the diversion plate through the dustproof block, causing the diversion plate to be in a state of vibration, so that the debris does not remain on the surface of the diversion plate, and the debris falls onto the working plate, which is convenient for the staff to clean.

[0038] The mounting base 1 is evenly distributed on the upper surface of the auxiliary plate 21, realizing the function of multi-station clamping and improving work efficiency. During the use of the device, the vise mounting plate 4 is placed on the top of the mounting base 1, and the two adjacent first threaded holes 9 are put together. The vise mounting plate 4 is fixedly installed on the top of the mounting base 1 by the first bolt 8. The connecting block 7 is engaged in the inner side of the connecting groove 6, and with the action of the second bolt 10 and the second threaded hole 11, the connecting block 7 is fixedly installed together with the vise mounting plate 4. Thus, the mounting base 1, the vise mounting plate 4 and the connecting block 7 are set as independent modules, reducing the difficulty of manufacturing device parts, and worn or damaged parts can be disassembled and replaced individually, reducing downtime and maintenance costs.

[0039] Example 2:

[0040] Based on Embodiment 1, by adjusting the configuration of the components, the position of the first clamping plates 14 on both sides of the device can be adjusted to clamp and limit the workpiece to be processed, which facilitates subsequent processing. The specific structure is shown in Figures 1, 4 and 5: The adjustment component includes a fixing block 12, the top of the fixing block 12 is fixedly connected to the bottom of the connecting block 7, and threaded rods 13 are rotatably connected to both the front and rear sides of the fixing block 12. An adjustment block is fixedly installed at the end of the threaded rod 13 away from the fixing block 12. The surface of the threaded rod 13 is threadedly connected to the first clamping plate 14. The top of the first clamping plate 14 is provided with a slot, and a second clamping plate 15 is engaged inside the slot. The bottom of the first clamping plate 14 is adapted to the groove. Sliding blocks 16 adapted to the sliding port 5 are fixedly installed on the left and right sides of the first clamping plate 14. The bottom of the fixing block 12 is provided with a connecting port 17 adapted to the connecting block 3.

[0041] During use, the device rotates by rotating the adjusting blocks on both sides, which in turn drive the threaded rod 13 to rotate. Through the threaded connection with the first clamping plate 14, the first clamping plate 14 slides back and forth inside the groove on the top of the mounting base 1, clamping and limiting the workpiece to be processed. The sliding block 16 slides inside the sliding opening 5, increasing the stability of the first clamping plate 14 during movement and enhancing its clamping effect.

[0042] Example 3:

[0043] Based on Embodiment 2, the clamping function of the device is increased by setting the second clamping plate 15 and the third bolt 18 to adapt to diverse workpiece clamping needs. Its specific structure is shown in Figures 4 and 5: The third bolt 18 is provided through the inner side of the second clamping plate 15 near the left and right sides and is threadedly connected to it. The top of the third bolt 18 is fixedly installed with a third nut. The top of the second clamping plate 15 is provided with a third rotating hole for the third nut to rotate. The inner side of the first clamping plate 14 is provided with a third threaded hole 19 that matches the third bolt 18.

[0044] During use, the second clamping plate 15 is engaged in the inner side of the slot. The second clamping plate 15 is fixedly installed inside the first clamping plate 14 through the threaded connection between the third bolt 18 and the third threaded hole 19. This allows the operator to quickly replace the second clamping plate 15 with different specifications to meet diverse workpiece clamping needs, ensuring clamping effect while taking into account practicality and economy.

[0045] Example 4:

[0046] As shown in Figures 7-10, an auxiliary plate 21 is movably disposed on the upper surface of the working plate 20, and a mounting base 1 is bolted to the upper surface of the auxiliary plate 21; a diversion plate 23 is fixedly connected to the upper surface of the working plate 20; a motor 22 is bolted to the inside of the working plate 20; a long pin 24 is fixedly connected to the output end of the motor 22; the end of the long pin 24 is fixedly connected to the bottom of the auxiliary plate 21; and a guide plate 25 is fixedly connected to the upper surface of the working plate 20.

[0047] A support column 26 is fixedly connected to the lower surface of the auxiliary plate 21, and a ball is rotatably arranged inside the support column 26. A groove corresponding to the ball is opened on the upper surface of the working plate 20. A movable plate 27 is slidably arranged on the surface of the guide plate 25, and a dustproof block 28 is fixedly connected to the surface of the movable plate 27. An inner rod 31 is fixedly connected to the inner wall of the movable plate 27, and an auxiliary spring 29 is fixedly connected to the surface of the movable plate 27. The other side of the auxiliary spring 29 is fixedly connected to the inner wall of the guide plate 25, and a limit block 30 is fixedly connected to the lower surface of the movable plate 27.

[0048] After the material is clamped, when the mounting base 1 needs to be rotated during the operation, the motor 22 inside the working plate 20 can be started. At this time, the motor 22 drives the long pin 24 and the auxiliary plate 21 to rotate. Not only can the angle be adjusted according to the actual situation, which is convenient for the operator, but also the centrifugal force can be used to discharge the debris during the processing. After the debris is discharged, it will fall onto the guide plate 23 and the working plate 20 and be collected by the operator.

[0049] When the auxiliary plate 21 rotates, the support column 26 and the ball bearings help to stabilize the auxiliary plate 21. At the same time, when the support column 26 rotates, it pushes the inner rod 31. When the inner rod 31 is pushed, the inner rod 31 and the movable plate 27 move to the side of the auxiliary plate 21 under the action of the thrust and the guide plate 25. At this time, the auxiliary spring 29 is compressed. When the inner rod 31 is not pushed, the inner rod 31 and the movable plate 27 move back under the action of the auxiliary spring 29. Repeating the above process, the inner rod 31 and the movable plate 27 make reciprocating linear motion in the horizontal direction. Then, the movable plate 27 intermittently hits the diversion plate 23 through the dust block 28, so that the diversion plate 23 is in a state of vibration, thereby preventing debris from remaining on the surface of the diversion plate 23.

[0050] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
