Proper leveling and clamping can improve machining accuracy and ensure consistent part quality.

[0003] Existing clamping fixtures for disc-shaped parts use multiple clamping components to fix the outer side of the disc-shaped parts. However, because the moving distance of the clamping components at different positions is different, the disc-shaped parts cannot be fixed in the exact center of the machining table. This results in the need to adjust the parameters according to the specific position of the parts during machining, which affects the accuracy of the machining. Utility Model Content

By rotating the second rotating cap 25, the rotating shaft 10 drives the gear 9 to rotate, thereby driving the rack 8 to move. The rack 8 drives the two movable boxes 2 to move the same distance through the connecting plate 7, thereby clamping the disc with the clamping plates 18 on both sides.

[0019] The movable box 2 has lugs 3 fixedly welded to its front and rear sides. A sliding rod 4 is slidably installed between the two sets of lugs 3. Side plates 5 are fixedly welded to both ends of the sliding rod 4 and are fixedly welded to the upper part of the table 1 to ensure that the movable boxes 2 move smoothly on both sides. The right connecting plate 7 has a connecting hole 20 that engages with the upper rack 8. When the movable boxes 2 on both sides approach each other, the rack 8 on the left side is inserted into the connecting hole 20 without affecting the continued movement of the movable box 2. A first bevel gear 12 is rotatably connected to the middle of the movable box 2. A first rotating cap 19 is fixedly welded to the tail of the first bevel gear 12. A second bevel gear 13 is meshed with both sides of the first bevel gear 12. A threaded rod 14 is fixedly welded to the tail of the second bevel gear 13. The tail of the threaded rod 14 is rotatably connected to the inner wall of the movable box 2. A moving block 15 is threadedly installed on the outer side of the threaded rod 14. The moving block 15 is fixedly welded to the connecting rod 16. By rotating the first rotating cap 19, the first bevel gear 12 drives the second bevel gear 13 to rotate, and the threaded rod 14 rotates to drive the moving block 15 to move, thereby driving the clamping plate 18 to maintain the same moving distance in the front and rear positions through the connecting rod 16; a limiting block 21 is fixedly welded to the outer front part of the rotating shaft 10, and a sliding piece 22 slides on the outer side of the rotating shaft 10 and the limiting block 21 to ensure that the sliding piece 22 rotates with the rotating shaft 10 at the same time. A toothed ring 23 is fixedly welded to the side of the sliding piece 22 facing the fixed plate 11. The fixed plate 11 has a toothed groove 24 that cooperates with the toothed ring 23. By inserting the toothed ring 23 into the toothed groove 24, the sliding piece 22 is locked. The sliding piece 22 locks the rotating shaft 10 through the limiting block 21, and fixes the left and right positions of the clamping plate 18; a spring 26 is fixedly welded between the sliding piece 22 and the second rotating cap 25. The spring 26 is sleeved on the rotating shaft 10. The spring 26 pushes the toothed ring 23 to prevent the toothed ring 23 from disengaging from the toothed groove 24.

[0020] Working principle: When this utility model is in use, by rotating the second rotating cap 25, the rotating shaft 10 drives the gear 9 to rotate, thereby driving the rack 8 to move. The rack 8 drives the two moving boxes 2 to move the same distance through the connecting plate 7, so that the two clamping plates 18 move the same distance left and right. By rotating the first rotating cap 19, the first bevel gear 12 drives the second bevel gear 13 to rotate, the threaded rod 14 rotates and drives the moving block 15 to move, thereby driving the clamping plate 18 to maintain the same moving distance in the front and back positions through the connecting rod 16, fixing the disc in the center position of the placement table 1, thus facilitating the processing of the disc.
