[0028] See also Figure 1-Figure 9 As shown, the utility model provides a positioning punching device, including a punching structure 1 and an extrusion structure 4, wherein a supporting structure 2 is provided at the lower end of the punching structure 1, through which the extrusion structure 4 is supported conveniently, so that before punching holes in the shoe upper, the extrusion structure 4 is driven to clamp the shoe upper, and two balls 3 are provided on the bottom side of the supporting structure 2, so that the staff can adjust the position of the shoe upper conveniently before punching holes in the shoe upper, so as to improve the accuracy of punching holes and facilitate subsequent positioning, and the supporting structure 2 and the extrusion structure 4 are connected to each other by a connecting structure 5, and the punching structure 1 includes a cylinder 101 and two extrusion blocks 102, and a punch 103 is fixedly provided at the lower end of the cylinder 101, so that the force transmitted by the cylinder 101 is conveniently received through the punch 103, so as to punch holes in the shoe upper.

[0029] The extrusion structure 4 includes two connecting blocks 401, two pressure blocks 405 and two return springs 404. A telescopic rod 403 is fixedly arranged inside the connecting block 401. The telescopic rod 403 and the return spring 404 form a buffer structure. When the extrusion block 102 pushes the pressure block 405, the pressure block 405 is buffered by the buffer structure to extend the service life of the pressure block 405. One end of the telescopic rod 403 is connected to the bottom of the pressure block 405. An extrusion plate 402 is fixedly arranged below the connecting block 401. Through the extrusion plate 402, it is convenient to adjust the pressure of the ball 3 After the shoe is in the correct position, the vamp is squeezed by the annular squeezing plate 402 to form a positioning clamp. The support structure 2 includes a connecting ring 201 and two supporting rods 202. When punching, the pressure block 405 on the telescopic rod 403 is squeezed by the squeezing block 102 on the cylinder 101, and then the telescopic rod 403 positions and clamps the vamp through the squeezing plate 402 on the connecting block 401. When the clamping is completed, the punch 103 continues to move toward the vamp through the cylinder 101, so that the telescopic rod 403 can be contracted, which is convenient for punching holes in the vamp through the punch 103.

[0030] Furthermore, a movable groove 203 is provided on the support rod 202, and the extrusion block 102 and the pressure block 405 can be slidably arranged inside the movable groove 203. Through the movable groove 203, the extrusion block 102 and the pressure block 405 can be conveniently moved and limited, and the cylinder 101 can conveniently push the extrusion block 102 to push the pressure block 405, so that the extrusion plate 402 on the connecting block 401 can clamp the shoe upper through the telescopic rod 403, and then the shoe upper can be punched through the punch 103.

[0031] Furthermore, the support rod 202 is fixedly arranged on the bottom side of the connecting ring 201 , and there are two support rods 202 , which is convenient for connecting the connecting block 401 and the extrusion plate 402 on the extrusion structure 4 , and is also convenient for connecting the ball 3 .

[0032] Furthermore, the connecting structure 5 includes a slide groove 502 and a slider 501. The slider 501 is fixedly arranged inside the connecting block 401. The slide groove 502 is opened on the inner front side of the support rod 202. When the extrusion plate 402 on the connecting block 401 clamps the shoe upper, the slider 501 on the connecting block 401 moves in the slide groove 502 on the support rod 202, so as to facilitate limiting the moving position of the connecting block 401 on the support rod 202.

[0033] Furthermore, the slider 501 is slidably arranged inside the slide groove 502, and a connecting spring 503 is fixedly connected between the slider 501 and the slide groove 502. Through the connecting spring 503, the extrusion plate 402 on the connecting block 401 can be easily reset through the slider 501, and can be used multiple times.

[0034] Furthermore, the extrusion block 102 is fixedly arranged on one side of the output end of the cylinder 101. When the cylinder 101 pushes the punch 103 to punch the shoe upper, the cylinder 101 first squeezes the pressure block 405 on the support rod 202 through the extrusion block 102, so that the support rod 202 drives the extrusion plate 402 on the connecting block 401 to squeeze the shoe upper.

[0035] Furthermore, the connecting ring 201 is fixedly arranged below the cylinder 101, and is connected to the cylinder 101 through the connecting ring 201, so that the structure can be formed into a whole for use, and the use steps are simplified, saving time and labor.

[0036] Furthermore, the reset spring 404 is fixedly connected to the inside of the telescopic rod 403. Through the reset spring 404, the telescopic rod 403 can be used to buffer the compressed block 405 and reset the telescopic rod 403, and the telescopic rod 403 can be used multiple times.

[0037] With the above structure, when the device is used, the punching device is moved to the upper, and then the upper is freely adjusted by the ball 3 on the punching structure 1. When the upper is to be punched, the punch 103 moves downward through the cylinder 101, and then the cylinder 101 squeezes the pressure block 405 through the extrusion block 102, and then the pressure block 405 drives the connecting block 401 to move through the telescopic rod 403, and then the upper is positioned and clamped by the annular extrusion plate 402 on the connecting block 401, and then the upper is punched by the punch 103.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
