[0028] Example:

[0029] The present application embodiment discloses a punching positioning fixture structure with an adjustment function. Figure 1 , comprising a workbench 1, the top of the workbench 1 is provided with two symmetrical connecting grooves 2, the top of the workbench 1 is slidably connected to two symmetrical moving frames 3, the bottoms of the two moving frames 3 are both installed with connecting plates 4, the connecting plates 4 are located inside the connecting grooves 2, and are sliding connection structures, the top of the workbench 1 is installed with two symmetrical electric push rods 5, the telescopic ends of the electric push rods 5 are connected to the moving frames 3, and one end of the two moving frames 3 is installed with a clamp assembly 6;

[0030] The connecting groove 2 and the connecting plate 4 are arranged so that the moving frame 3 is located on the top of the workbench 1 to slide, and the two electric push rods 5 can drive the two moving frames 3 to move. The distance between the two moving frames 3 can be expanded or reduced according to the size of the workpiece, so that the two moving frames 3 drive the clamping clamp 6 to clamp and fix the two ends of the workpiece. This structure is simple and convenient to operate;

[0031] See also Figure 2 and Figure 3The clamp assembly 6 includes a mounting seat 61 installed at one end of the mobile frame 3, and two symmetrical notches 62 are provided inside the mounting seat 61. Fixed rods 63 are installed inside the two notches 62. The outsides of the two fixed rods 63 are connected to moving seats 65. The moving seat 65 is slidably connected to the inside of the notches 62. Through holes are provided inside the moving seat 65 and at positions corresponding to the fixed rods 63. Springs 64 are installed on one side of the inside of the two notches 62. The springs 64 are located outside the fixed rods 63. One end of the spring 64 is connected to the moving seat 65. One end of the two moving seats 65 is rotatably connected to a connecting frame 66. One end of the two connecting frames 66 is rotatably connected to a connecting seat 67. A clamping plate 68 is installed at one end of the two connecting seats 67. An anti-skid pad 69 is installed on the lower surface of the clamping plate 68. The anti-skid pad 69 is made of rubber. An anti-skid groove is provided on the lower surface of the anti-skid pad 69. Lifting plates 610 are installed on both sides of the outside of the clamping plate 68.

[0032] The two movable seats 65 are located outside the two fixed rods 63 and slide. The user can move the position of the clamping plate 68 by holding the lifting plate 610. The anti-slip pad 69 is made of rubber material to increase friction and enhance the clamping effect.

[0033] The implementation principle of this embodiment is as follows: when some workpieces need to be punched and clamped, they can be fixed by two clamp assemblies 6. The staff first moves the two mobile frames 3 to a suitable position so that the two clamp assemblies 6 are located at the top two ends of the workpiece. When the staff fixes one end of the workpiece, they first operate a clamp assembly 6. The user holds the lifting plate 610 to drive the clamping plate 68 to move upward. When the clamping plate 68 moves, the two connecting seats 67 drive the two connecting frames 66 to move. The two connecting frames 66 drive the two moving seats 65 to move. The moving seats 65 are located at the fixed The outside of the fixed rod 63 moves and squeezes the spring 64, and after the distance between the clamping plate 68 and the table surface of the workbench 1 is expanded, one end of the workpiece is placed on the bottom of the clamping plate 68. At this time, the user releases the lifting plate 610, and the spring 64 drives the moving seat 65 to rebound. At this time, the surface of the anti-slip pad 69 set at the bottom of the clamping plate 68 fits with the top of the workpiece, so that one end of the workpiece can be clamped and fixed. Then, another clamp assembly 6 is operated in the same step as above to fix the other end of the workpiece. When both ends of the workpiece are fixed by the two clamp assemblies 6, the punching work can be carried out.

[0034] The spacing between the two clamp assemblies 6 can be adjusted according to the size of the workpiece. The user only needs to start the two electric push rods 5. The telescopic ends of the two electric push rods 5 respectively drive the two mobile frames 3 to move, so that the two clamp assemblies 6 are located at the top ends of the workpiece for adjustment, which is convenient for the two clamp assemblies 6 to clamp and fix the workpiece.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
