Description

Technical Field

[0001] The utility model relates to the technical field of bushing drilling technology, and specifically relates to a bushing side wall drilling mechanism. Background Art

[0002] At present, bushings are widely used in application fields such as valves and bearings. The use of bushings effectively solves the problems of valve sealing and friction between bearings. The materials and types of bushings are also different. According to different mechanical parts, the round bushings need to be processed again. Bushings with holes are one of the many types of bushings and are also widely used. At the same time, when punching the bushings, the requirements for the punching machine are relatively high.

[0003] During the process of drilling holes in the bushing, the bushing needs to be fixed so that holes can be drilled on the side wall of the bushing. However, the surface of the bushing is smooth, and the drilling machine is prone to slipping when drilling holes. In addition, the sizes of the bushings are different, and the traditional bushing drilling equipment cannot adjust the size and cannot process bushings of different sizes. Moreover, if the traditional bushing drilling equipment needs to drill multiple holes on the side wall of the bushing, the traditional bushing drilling equipment requires the staff to manually rotate the bushing to drill holes on the side wall of the bushing. The operation is not convenient enough, which reduces the working efficiency of the drilling machine. Utility Model Content
