[0035] To clamp the pipe processing parts, refer to Figures 1 to 5 In some optional embodiments, the pipe clamping assembly 32 includes a clamping fixed seat 321, a clamping drive device 322, a clamping synchronous belt module 323 and a clamping device 324, the clamping fixed seat 321 is arranged on the longitudinal moving plate 3123, the clamping drive device 322 and the clamping device 324 are both arranged on the clamping fixed seat 321, the clamping drive device 322 and the clamping device 324 are connected by the clamping synchronous belt module 323, wherein the clamping drive device 322 is used to drive the clamping device 324 to rotate the medical catheter of the tube placing platform 100; the clamping device 324 is used to clamp and fix the medical catheter of the tube placing platform 100.

[0036] It can be understood that with such a configuration, the clamping drive device 322 drives the clamping device 324 to rotate the medical catheter of the tube placing platform 100, and the clamping device 324 clamps and fixes the medical catheter of the tube placing platform 100, thereby realizing the clamping, rotating and fixing function of the tube clamping assembly 32.

In this embodiment, the clamping drive device 322 drives the active synchronous wheel 3231 to rotate, thereby driving the driven synchronous wheel 3232 and the synchronous belt 3233 to rotate synchronously, and then drives the clamping device 324 to rotate, thereby realizing precise transmission between the clamping drive device 322 and the clamping device 324.

[0038] In some optional embodiments, the clamping drive device 322 includes but is not limited to a driving motor, the clamping device 324 includes but is not limited to an air chuck, and the pipe inlet 33 and the pipe outlet 34 are arranged on the lateral sides of the air chuck, wherein after the medical catheter on the tube placement platform 100 enters the air chuck from the pipe inlet 33, the air chuck clamps the medical catheter; the driving motor drives the air chuck to rotate through the clamping synchronous belt module 323, thereby cooperating with the pipe grinding mechanism 400 to grind the medical catheter.

[0039] It can be understood that with such a setting, after the medical catheter on the pipe placement platform 100 enters the air-expanding chuck through the inlet pipe orifice 33, the air-expanding chuck clamps the medical catheter. The driving motor drives the air-expanding chuck to rotate through the driving synchronous pulley 3231, the driven synchronous pulley 3232 and the synchronous belt 3233, so as to cooperate with the pipe fitting grinding mechanism 400 to grind the medical catheter, realizing the stable clamping and rotation of the medical catheter. The air-expanding chuck has a good clamping effect, and the driving effect of the driving synchronous pulley 3231, the driven synchronous pulley 3232 and the synchronous belt 3233 is excellent.

[0040] To perform grinding on the pipe fitting processing parts, in some alternative embodiments, refer to Figures 1 to 5 , the pipe fitting grinding mechanism 400 includes a grinding tool assembly 41 and a pipe fitting positioning assembly 42. The grinding tool assembly 41 is arranged at the outlet pipe orifice 34, and the grinding tool assembly 41 and the pipe fitting positioning assembly 42 are arranged opposite to each other. Among them, the grinding tool assembly 41 is used to grind the medical catheter clamped on the air-expanding chuck, and the pipe fitting positioning assembly 42 is used to adjust and position the grinding length of the medical catheter.

[0041] In some alternative embodiments, the grinding tool assembly 41 includes a grinding tool device 411 and a grinding tool driving device 412.

It can be understood that with such a setting, the grinding tool driving device 412 drives the diamond grinding wheel to rotate, so as to grind the medical catheter clamped on the air-expanding chuck, realizing the function of grinding the pipe fitting processing parts in the embodiment of the present application.

[0042] To position the grinding of the pipe fitting processing parts, in some alternative embodiments, the pipe fitting positioning assembly 42 includes a second transverse movement unit 421, a second longitudinal movement unit 422 and a positioning module 423. The second transverse movement unit 421 is arranged on the second longitudinal movement unit 422, and the positioning module 423 is arranged on the second transverse movement unit 421. Among them, the second transverse movement unit 421 and the second longitudinal movement unit 422 are respectively used to drive the positioning module 423 to move horizontally and vertically to a preset position to adjust the distance between the positioning module 423 and the medical catheter. After the positioning module 423 is moved to the preset position, it is used to position the medical catheter to limit the grinding length of the medical catheter.

[0043] It can be understood that with such a setting, the second horizontal movement unit 421 cooperates with the second vertical movement unit 422 to drive the positioning module 423 to move horizontally and vertically. At the same time, the positioning module 423 restricts the grinding length of the medical catheter. Specifically, the second horizontal movement unit 421 cooperates with the second vertical movement unit 422 to drive the positioning module 423 to move to the front end of the outlet pipe 34. The positioning module 423 can abut against the end of the medical catheter extending from the outlet pipe 34, thereby limiting the medical catheter, and further determining the grinding length of the medical catheter. In this way, the positioning of the medical catheter is achieved, and thus after the medical catheter to be ground is ground by the diamond grinding wheel, the length and depth of the ground end of the medical catheter are consistent, the ground mouth is neat and uniform, and the grinding effect is good.

[0044] In some alternative embodiments, both the second horizontal movement unit 421 and the second vertical movement unit 422 include a driving cylinder, a moving seat, a slide rail and a slider. Among them, the driving cylinder drives the moving seat and the slider to slide on the slide rail, thereby driving the positioning module 423 to move horizontally or vertically correspondingly.

[0045] It can be understood that the driving mode of the driving cylinder and the transmission mode of the moving seat, the slide rail and the slider of the second horizontal movement unit 421 and the second vertical movement unit 422 enable the positioning module 423 to move more precisely, improving the movement accuracy of the positioning module 423.
