[0002] In modern manufacturing, automated punch presses, as efficient and precise processing equipment, are widely used in the stamping and forming processes of materials such as sheet metal, plastics, and composite materials. With the advancement of industrialization, the manufacturing industry has placed higher demands on the precision, efficiency, and safety of automated punch presses. Among these components, the clamp, as a crucial part of the punch press, primarily functions to clamp and secure the workpiece.

The outer surface of the T-shaped frame 6 is fixedly connected with a semi-toothed ring 14. The outer surface of the T-shaped frame 6 is provided with a through hole 22. The right surface of the first fixing plate 2 is provided with a locking hole 23. The right surface of the first fixing plate 2 is provided with a second threaded hole 24. The inner surface of the second threaded hole 24 is threadedly connected to the internal hexagon bolt 5, which facilitates the installation of the T-shaped frame 6. The outer surface of the T-shaped frame 6 is provided with a connecting hole 25. The outer surface of the base 1 is provided with a third threaded hole 26. There are four third threaded holes 26 distributed in a rectangular array, which facilitates the installation of the entire clamp structure. The pressure block 7 is made of polyurethane, which facilitates deformation to clamp and adjust the surface of workpieces of different shapes. The outer surface of the guide rod 9 is slidably connected to the connecting plate 11. The inner surface of the opening groove 8 is adapted to the connecting plate 11 and is used to limit the movement of the connecting plate 11. The rack 13 meshes with the semi-toothed ring 14, which facilitates the overall flipping of the T-shaped frame 6.

[0028] The limiting component 15 includes a sleeve 16, a pin 17, a limiting block 18, a pull rod 19, a pull ring 20, and a spring 21. The inner surface of the sleeve 16 is slidably connected to the pin 17. The right end of the pin 17 is fixedly connected to the limiting block 18. The right surface of the limiting block 18 is fixedly connected to the pull rod 19. The outer surface of the pull rod 19 is fixedly connected to the pull ring 20.

[0029] Working principle: First, the fixture is fixed to the equipment through the third threaded hole 26. Then, the pull ring 20 on the limiting assembly 15 is pulled, which drives the pull rod 19 to move the limiting block 18 and the pin rod 17 to the right, and compresses the spring 21, thereby disengaging the pin rod 17 from the through hole 22 to release the restriction on the T-shaped frame 6. Subsequently, the cylinder 10 is activated, which drives the connecting plate 11 to move the rack 13 under the action of the connecting rod 12. Then, under the meshing action of the rack 13 and the half-tooth ring 14, the T-shaped frame 6 and the pressure block 7 move inward as a whole. The angle bolt 5 is rotated around the axis, and then the pressure block 7 automatically clamps the surface of the workpiece. When the pressure block 7 clamps the surface of the workpiece, a certain amount of deformation will be generated, so that it can fit the surface contour of different shaped workpieces. At this time, the through hole 22 corresponds to the pin 17. Then, the pull ring 20 is released. Under the action of the spring 21, the pin 17 will be inserted into the through hole 22 and the locking hole 23 in sequence, thereby limiting the T-shaped frame 6 and the pressure block 7, which are in the clamping state at this time, to prevent loosening and thus improve the stability of clamping the workpiece.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
