New energy axle swing arm processing tooling

Abstract

A new energy vehicle axle swing arm processing tooling, which relates to a vehicle axle parts processing tooling, including a base, a swing arm outer profile positioning device, a swing arm inner profile positioning device, and an elastic auxiliary support component respectively installed on the base The outer contour positioning device of the swing arm is connected with the outer contour positioning of the swing arm workpiece, and the inner contour positioning device of the swing arm is connected with the inner contour positioning of the swing arm workpiece. In the present invention, the outer contour of the swing arm is positioned and compressed by using the base as the main body support frame, and the outer contour positioning device of the swing arm; the inner contour of the swing arm is positioned and compressed by the inner contour positioning device of the swing arm, thereby constraining 6 parts of the swing arm workpiece One degree of freedom enables the whole set of tooling to realize one-time clamping and processing, and adjusts and compensates the positioning error gap of the inner and outer contours of the swing arm through elastic auxiliary support components. Its processing accuracy is high, and it also has the characteristics of high processing efficiency and reliable structure. Promotional use.

Description

technical field [0001] The invention relates to a processing tool for axle parts, in particular to a new energy axle swing arm processing tool. Background technique [0002] The development trend of new energy vehicles has continued to expand in recent years. With the rapid development of new energy technologies for vehicles, urban buses have been promoted to have the characteristics of intelligence, light weight, and low emissions; independent suspension new energy axles have low emissions, The characteristics of low noise, high comfort and good operation stability can meet the development requirements of urban public transport. In this independent suspension rear axle system, the wheels on each side are independently suspended under the frame or vehicle body through elasticity, and an independent unilateral support suspension is formed by using a disconnected swing arm. The bouncing and tilting of the body takes up less space, and the space of the swing arm structure make...

Problems solved by technology

However, the current independent suspension new energy axles in the market are far from meeting the demand. The main reason is that the production capacity of special-shaped parts (such as swing arms) is low, and the processing accuracy cannot meet the requirements, and the processing of parts requires two or more times. Second clamping to complete the process
