Embodiment Construction

[0020] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments.

[0021] A processing technique for a shift lever bushing, characterized in that the following steps are adopted:

[0022] (1) Cutting: use bar material to cut on the sawing machine;

[0023] (2) Turning for the first time: one end of the blank obtained in step (1) is fixed on the lathe turning end face and outer circle;

[0024] (3) Turning for the second time: the product ring that step (2) obtains is fixed on the lathe turning end face, excircle and chamfering to the other end;

[0025] (4) Turning for the third time: the end faces of the two outer circles of the product obtained in step (3) are in contact with the end faces of the car to flat;

[0026] (5) Inner hole processing: the product obtained in step (4) is drilled with a circular inner hole by electric spark drilling, and the inner hol...

Abstract

The invention relates to a processing technology of a gear lever bushing. The processing technology comprises following steps: (1), discharging; (2), primary turning; (3), secondary turning; (4), tertiary turning; (5), inner hole processing; (6), inner hole diameter precision detection; (7), inner hole diameter roundness detection; (8), inner hole surface finish detection; (9), washing. According to the processing technology of the gear lever bushing, raw material consumption, labor-hour consumption and rejection rate can be reduced, and processing precision and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing technology for a shift rod bushing. Background technique [0002] In the automobile manufacturing industry, the shift lever bushing is generally made of a material with lower hardness and better wear resistance as the bushing or bushing, which can reduce the wear of the shaft and seat. When the bushing or bushing is worn to a certain extent, the Replacement, which can save the cost of replacing the shaft or seat. However, the existing processing method for the shift lever bushing has many processing steps, a large gap in the processing size, low processing accuracy, poor flexibility, and large consumption of raw materials, large man-hour consumption, and high scrap rate, which undoubtedly increases the cost of the bushing. Processing costs are not conducive to the long-term development of enterprises. [0003] Therefore, in view of these problems exis...
