Embodiment Construction

[0021] The present invention will be further described below according to the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 4 As shown, a processing method for steering the front axle of an underground tanker uses self-designed positioning tool 3 for auxiliary processing. The positioning tool 3 includes a bottom plate 3-3, and side plates 3-4 are vertically fixed on both sides of the bottom plate 3-3. , the top of the side plates 3-4 on both sides of the bottom plate 3-3 is provided with a top plate 3-5, and one side of the top plate 3-5 is obliquely upwardly provided with an angle of 7.5° towards the center of the top plate 3-5 from the side edge. Inclined surface I3-1, the side of the higher side of the inclined surface I3-1 or the side close to the higher side of the inclined surface I3-1 is provided with an inclined surface II3 obliquely downward in the direction away from the inclined surface I3-1 -2, the inclined surface II3-2 runs through ...

Abstract

The invention belongs to the technical field of axles, and particularly relates to a method for processing a steering front axle of an underground tank car. Steering shaft heads are welded at two endsof a front axle shell, and flange plates at two sides of the front axle shell are finely milled; the flange plates are taken as positioning references to perform fixing with a positioning tool; firstly lower joint surfaces of the steering shaft heads are milled, then main pin holes are finely bored, and then upper joint surfaces of the steering shaft heads are milled; after processing of the lower joint surfaces, the main pin holes and the upper joint surfaces is finished, a steering front axle is placed on a rocker arm drilling machine, and the steering shaft heads at two sides of the steering front axle are drilled to form small pin holes. The processing method provided by the invention avoids the problems that deformation is large and the position degree of the shaft heads is changed during hot assembly due to the fact that the steering shaft heads are processed first and then are welded on the front axle shell.

Description

technical field [0001] The invention belongs to the technical field of vehicle axles, and in particular relates to a processing method for a steering front axle of an underground tank car. Background technique [0002] The steering front axle of the underground tanker is a device that transmits the force between the frame and the front wheel and generates bending moment and torque during the whole running process of the tanker, and the steering shaft head passes through the bearing and the main The pin assembly is connected with the steering knuckle, which plays a very critical role in the steering and operation of the tanker. [0003] The process route of the steering shaft head parts is firstly formed by forging or blanking of steel plates into blanks, and then semi-finished parts are formed through finishing turning, and then through the welding seam cutout of the shaft and the shaft head and the front axle housing are hot-assembled and welded to form a whole axle blank....
