Method for machining wheel surface of torsion beam rear axle

Abstract

The invention provides a method for machining a wheel surface of a torsion beam rear axle and relates to the field of machining of torsion beam rear axles. A torsion beam, a trailing arm and a wheel arc surface on the outer side of the torsion beam are included. The method comprises the following steps: (1) the torsion beam is placed on a machining platform and fixed by a clamp piece on the machining platform, and one end of the torsion beam extends out of a table face of the machining platform; and (2) a U-shaped groove support base is connected to the outer surface of the machining platformthrough a slide rail, and a groove wall of the U-shaped groove support base is clamped with a beam arm of the torsion beam. According to the method, as a sander, the machining platform and abrasive paper are arranged, and a fixed seat lifts up the sander, chippings can conveniently fall into a collection tank body; the abrasive paper performs secondary sanding on the wheel arc surface; the unevenconvex surface of the wheel arc surface is ground flush by machining shaking of an edge side and an edge corner of the wheel arc surface; and therefore, the surface of the wheel arc surface is smooth,and the follow-up machining is facilitated.

Description

technical field [0001] The invention relates to the technical field of torsion beam rear axle processing, in particular to a method for processing a torsion beam rear axle wheel surface. Background technique [0002] The rear axle refers to the rear drive shaft component of the vehicle power transmission. It is composed of two half-axles, which can implement the differential movement of the half-axles. At the same time, it is also a device for supporting the wheels and connecting the rear wheels. If the vehicle is driven by the front axle, then the rear axle is just a follower axle, which only plays the role of load bearing. If the front axle is not a drive axle, then the rear axle is a drive axle. And deceleration also has the effect of differential speed. If it is four-wheel drive, it is generally equipped with a transfer case in front of the rear axle. According to the suspension of the axle, it is divided into integral type and disconnected type. The working principle is...
