Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] The machining method of the automobile non-drive axle steering knuckle of the present invention, its steps are as follows:

[0059] The first step is to drill the center hole of the shaft end: see figure 1 , Drill a central hole 1-1 at the shaft end on the end face of the shaft 1 of the steering knuckle blank of the non-drive axle of the automobile;

[0060] The second step, roughing the outer circle: see figure 2 , positioning with the center hole 1-1 of the shaft end and the inner cavity of the frame end 2 of the steering knuckle blank of the non-drive axle of the automobile;

[0061] The third step is to punch the center hole at the end of the frame: see image 3 , clamp the outer circle of the shaft 1 of the steering knuckle blank of the non-drive axle of the automobile, and drill a frame end center hole 2-1 in the inner cavity of the frame end 2;

Abstract

The invention discloses a machining method of an automotive non-driven vehicle-bridge steering knuckle. The method comprises the following steps: (1) forming an axle-end central hole; (2) coarsely turning; (3) forming a frame-end central hole; (4) drilling the axle-end central hole for the second time; (5) coarsely processing a main pin hole; (6) polishing a central hole; (7) performing half-finish turning on an axle; (8) performing finish turning; (9) polishing the outer circle of the axle; (11) finishing the main pin hole and the end face thereof; (12) drilling a threaded hole and a bottom hole on the end face of the main pin hole; (13) tapping screw threads; (14) milling an arc R; (15) milling a fastening groove; and (16) cleaning the parts and conveying the parts to an inspection section. By improving the procedures in the machining process, the method can reduce the loads of drilling processes, reduce the machining cost, shorten the production period, and improve the product quality.

Description

technical field [0001] The invention belongs to the processing method of auto parts, in particular to the machining method of the steering knuckle of the non-drive axle of the automobile. Background technique [0002] Facing fierce competition in the axle market, only by continuously improving the design and process and grasping the quality and quantity of products can it meet the needs of the market economy. After the improved design of the current non-drive axle steering knuckle of automobiles, there is no through hole on the shaft, but in the actual processing process, it is still necessary to process multiple process holes on the shaft for positioning in the subsequent process, and each process hole is in the product It is not necessary for use, which will undoubtedly increase the burden of the drilling process, increase the machining cost, and prolong the production cycle. Moreover, the accuracy of the hole will also affect the positioning accuracy and thus affect the p...
