A fixed base 2 is provided on the side of the punch press body 1, and a clamp body 3 is provided on the surface of the fixed base 2. The clamp body 3 includes a mounting plate... The mounting base 4 has an internal mounting groove 23. A telescopic rod 14 is housed inside the mounting groove 23, and a connecting block 18 is provided on the surface of the telescopic rod 14. The connecting block 18 is fixedly connected to the telescopic rod 14. Side guide posts 20 are provided on both sides inside the mounting groove 23, and side movable seats 19 are provided on the surface of the side guide posts 20. A mounting bracket 21 is provided on the side of the side movable seat 19, and a drive connecting rod 22 is provided between the mounting bracket 21 and the connecting block 18. A side clamp 10 is provided on the surface of the side movable seat 19. A movable groove 9 is provided on the surface of the mounting base 4, and the side clamp 10 is located inside the movable groove 9. A sliding groove 11 is provided on the side of the mounting base 4, and a main movable seat 12 is housed inside the sliding groove 11. The main movable seat 12 and... The telescopic rods 14 are fixedly connected. A main guide column 15 is provided inside the sliding groove 11 and is connected to the main movable seat 12. A main chuck 16 is provided on the surface of the main movable seat 12. A fixed limiting block 8 is provided on the surface of the mounting seat 4. A cylinder connection hole 6 is provided on the side of the mounting seat 4. The drive rod of the external drive cylinder is inserted into the cylinder connection hole 6 and connected to the telescopic rod 14, thereby driving the telescopic column to move left and right, thereby driving the main movable seat 12 to move so that the main chuck 16 and the limiting block 8 fix the punch. At the same time, while the connecting block 18 moves, it drives the side movable seat 19 to move through the drive connecting rod 22, so that the side chuck 10 clamps the two sides of the punch to ensure the stability of the punch.

[0020] Further improvements, such as Figure 1 As shown: The mounting base 4 has several sets of mounting holes 5 inside, and the mounting base 4 is fixedly connected to the fixed base 2 by bolts passing through the mounting holes 5. The mounting base 4 and the fixed base 2 are fixed by bolts passing through the mounting holes 5, which enhances the connection stability and firmness between the fixture body 3 and the punch press body 1.

[0021] Further improvements, such as Figure 1 As shown: The surface of the mounting base 4 is provided with several sets of adjustment holes 7 and the limiting fixing block 8 is fixedly connected to the adjustment holes 7 by bolts. The multiple sets of adjustment holes 7 allow the limiting fixing block 8 to be flexibly adjusted according to the size and shape of the punch, which enhances the versatility and adaptability of the fixture.

[0022] Further improvements, such as Figure 3 As shown: The mounting surfaces of the side movable seat 19 and the main movable seat 12 are both provided with adjustment grooves 13. The side chuck 10 and the main chuck 16 are fixedly connected to the adjustment grooves 13 by bolts. The design of the adjustment grooves 13 allows the side chuck 10 and the main chuck 16 to be finely adjusted according to the specific size of the punch, which further improves the clamping accuracy and stability.

[0023] Further improvements, such as Figure 4 As shown: The drive linkage 22 is rotatably connected to the mounting bracket 21 and the connecting block 18. The rotatable connection design reduces friction and resistance during the drive process, making the movement of the side movable seat 19 smoother and more efficient, and improving the response speed and clamping force of the clamp.

[0024] Further improvements, such as Figure 4 As shown: The surface of the telescopic rod 14 is provided with a spring post 17, and the two ends of the spring post 17 are fixedly connected to the connecting hole and the mounting groove 23 respectively. The spring post 17 plays a role in buffering and resetting. When the telescopic rod 14 is subjected to external force, the spring post 17 can absorb part of the impact force and protect the clamp structure from damage. At the same time, after the telescopic rod 14 completes the clamping action, the spring post 17 can help it quickly reset, preparing for the next clamping.

[0025] Working principle: The mounting base 4 is fixed to the fixed base 2 of the punch press body 1 by bolts through the mounting hole 5, ensuring that the clamping body 3 is stable and reliable. According to the size and shape of the punch, the position of the limit fixing block 8 in the adjustment hole 7 is adjusted and fixed with bolts to adapt to the limit requirements of different punches. Through stable installation and flexible adjustment, a stable foundation and wide adaptability are provided for subsequent clamping work. The drive rod of the external drive cylinder is inserted into the cylinder connection hole 6 and connected to the telescopic rod 14. When the cylinder is started, the drive rod drives the telescopic rod 14 to move left and right. The movement of the telescopic rod 14 is transmitted to the main moving base 12 and the drive connecting rod 22 through the connecting block 18. The cylinder drive provides A stable and powerful power source ensures the accuracy and force of the telescopic rod 14's movement, providing reliable power for clamping the punch. The movement of the telescopic rod 14 drives the main movable seat 12 to slide along the main guide column 15, causing the main chuck 16 to move towards the limiting fixing block 8, thus initially fixing the punch. The movement of the connecting block 18 drives the side movable seat 19 to slide along the side guide column 20 via the driving link 22, causing the side chuck 10 to move towards both sides of the punch, further clamping and fixing the punch. The synergistic effect of the main chuck 16 and the side chuck 10 realizes multi-point and multi-directional clamping of the punch, greatly improving the stability and accuracy of the punch during processing and effectively preventing the punch from shifting and sliding.
