[0004] To solve the technical problem, the utility model provides a puncher that can automatically control the size of punching. UTILITY MODEL CONTENTS

[0005] The main purpose of the utility model is to provide a puncher that can automatically control the size of punching, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0007] A puncher that can automatically control the size of punching, comprising a mounting block, the lower end of the mounting block is provided with a punching needle, the punching needle is elongated and conical, the upper end of the mounting block is connected with a pressing rod, the upper end of the pressing rod is connected with a No. 1 air cylinder, the side end of the No. 1 air cylinder is connected with a laser range finder, the side end of the No. 1 air cylinder is connected with a protective tube, the side end of the mounting block is connected with a supporting rod, the upper end of the supporting rod is connected with a ranging plate, the lower end of the punching needle is provided with a processing plate, the processing plate is provided with a processing hole, and the front end of the No. 1 air cylinder is provided with a controller.

[0008] Preferably, the punching needle has high strength and smooth outer surface, the lowermost end of the punching needle is provided in a pointed shape, and the laser range finder and the controller are connected through a data line.

[0009] Preferably, the laser range finder is located at the upper end of the protective tube, the laser head thereof is located in the protective tube, the protective tube is vertically arranged, and the supporting rod and the ranging plate are slidingly connected in the protective tube.

[0010] Preferably, the laser range finder is located at the upper end of the range board, the laser range finder hits the range laser on the range board, the processing plate is located at the lower end of the punching needle, and the punching needle can be completely inserted into the processing hole.

[0011] Preferably, the first cylinder side end is provided with the second cylinder, the second cylinder is connected with the regulator through the data line, the second cylinder driving end is connected with the moving plate, the moving plate is slidingly connected to the outer end of the pressing rod, and the moving plate lower end is connected with the connecting rod.

[0012] Preferably, the connecting rod is slidingly connected in the mounting block, the connecting rod lower end is connected with the pressing ring, the connecting rod and the pressing ring are located at the outer end of the punching needle, the pressing ring lower end is connected with the rubber pad, and the radius of the pressing ring is larger than that of the processing hole.

[0013] Preferably, the processing plate lower end is connected with the fixed rod, the length of the fixed rod is longer than that of the punching needle, the fixed rod lower end is connected with the bottom plate, the fixed rod lower end is connected with the bottom plate, the bottom plate is connected with the first cylinder and the second cylinder through the support frame.

[0014] Compared with the prior art, the utility model has the advantages of the following beneficial effects:

[0015] In the utility model, the punching needle is conical, and the hole on the punching plate gradually increases when the punching needle continuously inserts into the processing hole. Therefore, the size of the hole punched by the punching needle is related to the moving distance of the punching needle, and the two are in a functional relationship. The laser range finder can detect the distance between the laser head and the range board. The range board and the punching needle are connected to the same mounting block. Therefore, the moving distance of the punching needle is the same as that of the range board. The value detected by the laser range finder corresponds to the moving distance of the punching needle. Therefore, the detection value of the laser range finder can be in a functional relationship with the size of the hole punched by the punching needle. Therefore, by setting the size of the hole, the corresponding detection value of the laser range finder can be found. Therefore, by setting the size of the hole through the regulator, the punching needle is pushed to punch a hole by the first cylinder. When the value detected by the laser detector reaches the corresponding value of the set hole, the regulator stops the first cylinder, thereby determining the size of the hole punched by the punching needle. The device can automatically control the size of the hole, which is not only simple to operate, high in punching precision and high in processing efficiency, but also can realize different sizes of the hole, good in flexibility and strong in applicability.

[0016] In this invention, a second cylinder and a lower pressure ring are provided. Before the punching needle drills into the punching plate, the second cylinder is activated to move the moving plate downwards. This, in turn, drives the lower pressure ring downwards via the connecting ring, causing the lower pressure ring to act on the punching plate. This applies pressure to fix the punching plate around the hole, ensuring that the punching plate remains stable during the punching process and does not move or deform due to the impact of the punching needle. This improves the precision and accuracy of the punching. Furthermore, when the punching needle is withdrawn from the processing hole, the connecting ring can prevent the punching plate from moving, thus facilitating the removal of the punching needle from the punching plate and making it easier to unload the punching plate.
