Abstract

The invention discloses a fixture for machining the outer cylindrical surface of a shaft sleeve. A side plate and a fixed block are disposed on a fixture base. A cylindrical boss is arranged on the side plate. A threaded hole is arranged on the fixed block and is connected with a screw in threaded manner. The shaft sleeve can be positioned by horizontally placing the shaft sleeve between the screw and the boss and directly turning the screw. The fixture is simple in structure and convenient to operate, can be used to well clamp and position the shaft sleeve, and can be used to machine the outer cylindrical surface of the shaft sleeve for multiple features by single clamp-positioning.

Description

[0001] technical field [0002] The invention relates to a fixture, in particular to a fixture for machining the outer peripheral surface of shaft sleeve parts. [0003] Background technique [0004] A shaft sleeve part used on a sewing machine, its two ends are provided with a central hole extending along the length of the part, and its peripheral surface has other features, which need to be completed by machining, and this type of part is relatively Small, the traditional fixture cannot complete the processing of multiple features on the outer surface of its circumference after one clamping, and it needs to be clamped and positioned by a special fixture. [0005] Contents of the invention [0006] The object of the present invention is to provide a fixture for processing the outer peripheral surface of shaft sleeve parts, so that the processing of multiple features of the outer peripheral surface of shaft sleeve parts can be completed after one clamping and positionin...
