Abstract

The invention discloses a shaft sleeve surface quenching fixture which comprises a base, an upright post, a lower die holder, a separation disc, an upper die holder, a pressing block, an adjusting washer, a first fixing disc, a second fixing disc, a wedge-shaped bolt and rotating discs, wherein the upright post is arranged on the base; the lower die holder, the separation disc, the upper die holder, the pressing block and the adjusting washer are sequentially arranged on the upright post from bottom to top in a sleeving manner; the diameter of the separation disc is smaller than the diameter of the disc of the upper die holder; the first fixing disc is arranged outside the lower die holder in a sleeving manner; the second fixing disc is arranged outside the upper die holder in a sleeving manner; a bolted hole is formed in the upright post; the wedge-shaped bolt is inserted into the bolted hole; when the wedge-shaped bolt is inserted into the bolted hole, the wedge-shaped bolt is close to the adjusting washer; multiple through holes are formed in positions, which are close to the outer end, of the disc of the upper die holder in an annular array; and multiple rotating discs are arranged in the separation disc. According to the shaft sleeve surface quenching fixture disclosed by the invention, after one-step surface quenching is finished, the detachment operation is convenient, various parts of the fixture are not damaged during detachment, and the shaft sleeve surface quenching fixture is high in quenching efficiency and suitable for large-scale surface quenching.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for quenching the surface of a shaft sleeve, and belongs to the technical field of mechanical quenching. Background technique [0002] General shaft sleeve processing will include a surface quenching step. The purpose of surface quenching is to obtain a surface with high hardness and high wear resistance. Surface quenching is to harden the surface layer of the steel part to a certain depth, while the core part is still A method of partial quenching that maintains the unquenched state. Surface quenching must use fixtures. The previous quenching fixtures are locked before use, which makes it difficult to disassemble after one surface quenching, and can only handle a small amount of surface quenching, but cannot deal with large quantities of surface quenching. Contents of the invention [0003] The purpose of the present invention is to provide a shaft sleeve surface quenching fixture which...
