It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a leather punching machine suitable for leather processing, including a processing table 1, an L-shaped bracket 4 fixedly installed on the surface of the processing table 1, a cylinder 5 fixedly installed on the bottom surface of the horizontal end of the L-shaped bracket 4, and a punching head 6 fixedly installed on the output end of the cylinder 5.

[0025] The specific setup and function of its auxiliary device 2 and clamping device 3 will be explained below.

[0026] In this embodiment: Auxiliary devices 2 are provided on both sides of the processing table 1. The auxiliary devices 2 include two through slots 201. The two through slots 201 are opened on both sides of the processing table 1. A round rod 202 is fixedly installed between the inner walls of the two ends of the through slot 201. A horizontal bar 203 is slidably connected between the two round rods 202. A vertical plate 204 is fixedly installed on the surface of the horizontal bar 203. A placement plate 205 is fixedly installed at the end of the vertical plate 204 away from the horizontal bar 203.

[0027] In this embodiment, the round rod 202 allows the horizontal bar 203 to move.

[0028] Specifically, two support plates 206 are fixedly installed on the surface of the processing table 1, and a threaded rod 207 is rotatably connected between the two support plates 206. A motor 208 is fixedly installed on the surface of one of the support plates 206, and the output end of the motor 208 is fixedly connected to the threaded rod 207.

[0029] In this embodiment, the motor 208 is configured to drive the threaded rod 207 to rotate.

[0030] Specifically, the surface of the processing table 1 has an elongated groove 209, and a movable plate 210 is threadedly connected to the surface of the threaded rod 207. A connecting rod 211 is fixedly installed between the movable plate 210 and the crossbar 203. The connecting rod 211 serves to move the crossbar 203 on the surface of the round rod 202.

[0031] In this embodiment: the surface of the placement plate 205 is provided with a pressing device 3, the pressing device 3 includes two uprights 31, the two uprights 31 are fixedly installed on the surface of the placement plate 205, and the surfaces of the two uprights 31 are slidably connected with pressing plates 32. When it is necessary to press and fix the leather onto the surface of the placement plate 205, first lift the operating lever 36 upwards. The upward movement of the operating lever 36 causes the moving plate 35 to move on the surface of the slide rod 34. The movement of the moving plate 35 on the surface of the slide rod 34 will compress the spring 38, causing the spring 38 to be compressed. At the same time, the movement of the moving plate 35 on the surface of the slide rod 34 also causes the pressing plate 32 to move on the surface of the upright rod 31. The movement of the pressing plate 32 on the surface of the upright rod 31 will move it away from the surface of the placement plate 205. When the pressing plate 32 moves to the appropriate position, the leather can be placed on the surface of the placement plate 205. After placement, release the operating lever 36. The spring force of the spring 38 will cause the pressing plate 32 to return to its original position. The return of the pressing plate 32 will then press and fix the leather onto the surface of the placement plate 205. Through the cooperation of the above structures, the purpose of pressing and fixing the leather is achieved, avoiding displacement of the leather during punching and preventing deviation of the punching position.

[0032] Specifically, two rectangular plates 33 are fixedly installed on one side surface of the placement plate 205. Slide rods 34 are fixedly installed on the surface of each of the two rectangular plates 33. A movable plate 35 is slidably connected to the surface of the slide rods 34. The side of the movable plate 35 is fixedly connected to the pressing plate 32. An operating rod 36 is fixedly installed between the two movable plates 35.

[0033] In this embodiment, the operating lever 36 is designed to move the movable plate 35 on the surface of the slide bar 34.

[0034] Specifically, a circular plate 37 is fixedly installed at the end of the slide bar 34 away from the rectangular plate 33, and a spring 38 is fixedly installed between the circular plate 37 and the movable plate 35.

[0035] In this embodiment, the spring 38 serves to limit the position of the moving plate 35 on the surface of the slide bar 34.

[0036] Working principle: By setting auxiliary device 2, when the device is needed, first place the leather on the surface of the placement plate 205, then start the motor 208. The motor 208 drives the threaded rod 207 to rotate. The rotation of the threaded rod 207 drives the movable plate 210 to move inside the long groove 209. The movement of the movable plate 210 inside the long groove 209 drives the connecting rod 211 to move. The movement of the connecting rod 211 drives the horizontal bar 203 to move on the surface of the round rod 202. The movement of the horizontal bar 203 on the surface of the round rod 202 drives the vertical plate 204 to move. 04. The movement of the placement plate 205 causes the leather to move. When the placement plate 205 moves the leather to below the punching head 6, the cylinder 5 is opened. The cylinder 5 moves the punching head 6 downward, thereby completing the punching operation of the leather. Through the cooperation of the above structure, it is not necessary to place the leather under the punching head 6, avoiding the punching head 6 falling due to operational errors and causing harm to the workers' bodies. This improves the safety of workers operating the punching device and reduces the harm to workers' bodies caused by operational errors. When it is necessary to press and fix the leather onto the surface of the placement plate 205, first lift the operating lever 36 upwards. The upward movement of the operating lever 36 causes the moving plate 35 to move on the surface of the slide rod 34. The movement of the moving plate 35 on the surface of the slide rod 34 will compress the spring 38, causing the spring 38 to be compressed. At the same time, the movement of the moving plate 35 on the surface of the slide rod 34 also causes the pressing plate 32 to move on the surface of the upright rod 31. The movement of the pressing plate 32 on the surface of the upright rod 31 will move it away from the surface of the placement plate 205. When the pressing plate 32 moves to the appropriate position, the leather can be placed on the surface of the placement plate 205. After placement, release the operating lever 36. The spring force of the spring 38 will cause the pressing plate 32 to return to its original position. The return of the pressing plate 32 will then press and fix the leather onto the surface of the placement plate 205. Through the cooperation of the above structures, the purpose of pressing and fixing the leather is achieved, avoiding displacement of the leather during punching and preventing deviation of the punching position.
