Description

Technical Field

[0001] The utility model relates to the technical field of universal shaft processing, and more specifically, to a deburring device for universal shaft production. Background Art

[0002] A universal joint is a transmission component that can transfer kinetic energy in other directions. It is composed of three shaft sections connected by two vertical pins that are perpendicular to each other in space. This ensures that power can be transmitted smoothly even when the center lines of the two shafts are at a certain angle. During the production and processing of the universal joint, the surface burrs need to be processed to prevent them from affecting the normal use of the universal joint.

[0003] In existing institutions, the deburring method is manual deburring by operators, which is relatively inefficient. At the same time, manual deburring is also dangerous and may cause cuts.

[0004] After searching, the Chinese patent with authorization announcement number CN219767845U discloses a deburring device for processing raw materials of universal joint drive shaft. The structure drives the partition plate to move upward through the lifting component, thereby driving the steel ball layer on the partition plate to move upward, so that the rotating frame is immersed in the steel ball layer, and then the rotating frame is driven to rotate by the rotating component, so that the rod material in the rotating frame can contact with the steel ball to achieve the purpose of grinding and deburring. The operation is simple and convenient, and the purpose of automatic deburring is achieved, avoiding the occurrence of cuts, and facilitating the removal and grinding and deburring of raw materials. At the same time, a guide rod is provided, which can play a role of limiting and guiding the movement of the partition plate, thereby increasing the stability of the movement of the partition plate.

[0005] However, when this structure is actually used, the rotating frame is driven to rotate by the rotating component, so that the rod in the rotating frame can contact the steel ball to achieve the purpose of grinding and deburring. Only the two ends of the rod can be ground and deburred, and burrs still remain on the surface of the rod, resulting in unexpected removal, thereby affecting the work quality. Utility Model Content
