Description

Technical Field

[0001] The utility model relates to the technical field of prosthetic processing, in particular to a prosthetic processing mechanism. Background Art

[0002] Prostheses are used to make up for the limbs of amputees or those with incomplete limb loss. They are mainly composed of an internal frame and external simulated skin. A large number of burrs will be generated on the surface of the prosthetic frame during processing. The burrs on the surface of the prosthetic need to be polished on a grinding table to improve the processing quality of the prosthesis.

[0003] The patent specification with the announcement number CN218051875U discloses a polishing device for prosthetic production, including a workbench, support legs are welded at the four corners of the bottom wall of the workbench, a vertical plate is welded on one side of the upper wall of the workbench, a slot is provided on the vertical plate, a lifting plate slides up and down in the slot, a polishing assembly and a dust suction assembly are provided on the lifting plate, a slide column is welded on the front and back of the upper wall of the workbench, a slide column is provided on the upper wall, a moving block is slidably connected to the opposite sides of the slide, a clamp is welded on the upper wall of the moving block, a bidirectional screw is rotatably connected between the inner walls of the opposite sides of the slide, a transmission assembly is connected between the two bidirectional screws, one end of one bidirectional screw away from the pulley is connected to a connecting shaft 1, and the other end of the connecting shaft 1 is connected to a hand wheel 1. Compared with the prior art, the utility model has the advantages of being able to clamp the two sides of the prosthesis, having a better fixing effect on the prosthesis, being simple and convenient to operate, and improving work efficiency.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned polishing device for prosthetic production has the following problems: the device drives the moving block to move by rotating the bidirectional screw, and drives the lifting plate to move by the lead screw. When the polishing wheel polishes the prosthetic limb, the debris generated by the polishing flies at a relatively fast speed, making it impossible for the air inlet duct to absorb all the debris. The debris is easily splashed onto the surface of the bidirectional screw and the lead screw, which may cause blockage at the connection between the bidirectional screw and the moving block, or blockage at the connection between the lead screw and the lifting plate, resulting in the grinding wheel being unable to rise and fall normally or the splint being unable to move normally, thereby reducing the polishing efficiency of the device for the prosthetic limb. In view of this, a prosthetic processing mechanism is provided to overcome the above-mentioned defects. Utility Model Content
