Positioning device for rough milling of inner and outer sides of upper and lower lugs of steering knuckle

Abstract

The invention relates to the technical field of steering knuckle machining devices, and discloses a positioning device for rough milling of inner and outer sides of upper and lower lugs of a steering knuckle, which comprises a base and a positioning device body arranged on the base, wherein the positioning device body comprises a V-shaped seat used for positioning a workpiece journal, a disc part positioning plate used for positioning a disc part and a pressing mechanism used for pressing the shaft neck of the workpiece, the V-shaped seat is detachably connected with the base; positioning of products at different angles can be met by rotating the V-shaped seat out of different angles, the universality is good, and the shaft neck of the workpiece is positioned through the V-shaped seat, so that automatic centering of the axis of the shaft neck of the workpiece can be realized, the positioning errors can be effectively reduced, and thus, the machining precision is higher; the workpiece is pressed on the V-shaped seat through the pressing mechanism, so that the clamping is firmer and firmer; the upper and lower lugs of the workpiece are further supported and pressed through a lug supporting and positioning device, so that the workpiece cannot transversely move in the machining process, and thus, the clamping stability is further improved.

Description

technical field [0001] The invention relates to the technical field of steering knuckle processing devices, in particular to a rough milling positioning device for the inner and outer sides of the upper and lower ears of the steering knuckle. Background technique [0002] The steering knuckle (horn) is one of the main parts on the steering axle of a car. Generally, the front axle of a truck is a steering axle. Its function is to bear the load of the front wheel of the car, support and drive the front wheel to rotate, etc. [0003] The steering knuckle is mainly composed of the steering knuckle journal, disc, upper and lower ears, etc. It effectively connects the braking system, steering system and suspension system of the car through different parts, and plays the dual tasks of steering and bearing. It transmits and bears the front load of the car, supports and drives the front wheel to rotate around the kingpin to make the car turn. When the car is running, it bears variab...

AI Technical Summary

Problems solved by technology

[0004] During the processing of the steering knuckle, it is necessary to mill the inner and outer sides of the upper and lower ears to meet the connection requirements with other auto parts. During the milling process, the workpiece to be processed first needs to be clamped and fixed. , the general clamping method cannot be fixed well, and manual assistance is required, so the skill proficiency of the workers is high, and in the milling process, the tool rotates continuously, which will cause the steering knuckle to shake, thus affecting the steering knuckle. Machining accuracy leads to low product qualification rate, it is difficult to meet the assembly requirements of auto parts, and the work efficiency is low
