Abstract

The invention discloses a fine processing method of a shifting block of a vehicle transmission. The method is that the top work surface of the shifting block is finely processed through a top work surface processing grinding machine; the bottom work surface of the shifting block is finely processed through a bottom work surface processing grinding machine; the surface roughness Ra of the top work surface and the bottom work surface of the shifting block is not greater than 0.4 microns, so that the operation experience in shifting can be increased.

Description

technical field [0001] The invention relates to a machining method, in particular to a finishing method for a shift block of a vehicle transmission. Background technique [0002] The shift block of the vehicle transmission is used for the shift operation of the vehicle during driving. The common problem of the existing shift blocks is that the operating experience during the shifting process is not good. [0003] For this purpose, a figure 1 , figure 2 The shift block of the vehicle transmission shown includes a block body 1-1, and a lug 1-2 is formed on one side of the block body 1-1; The connection hole 1-3, the connection hole 1-3 extends along the length direction of the block body 1-1; [0004] The bottom surface and the top surface of the block body 1-1 are working surfaces when shifting gears; the surface machining accuracy of the working surface directly determines the smoothness of shifting gears; the bottom working surface of the block body 1-1 is an arc surfa...
