New energy vehicle axle swing arm machining tool

Abstract

The invention discloses a new energy vehicle axle swing arm machining tool, and relates to a vehicle axle spare part machining tool. The new energy vehicle axle swing arm machining tool comprises a pedestal, a swing arm outer contour positioning device, a swing arm inner contour positioning device and an elastic auxiliary supporting assembly, wherein the swing arm outer contour positioning device,the swing arm inner contour positioning device and the elastic auxiliary supporting assembly are installed on the pedestal. The swing arm outer contour positioning device and the outer contour of a swing arm workpiece are in positioning connection, and the swing arm inner contour positioning device and the inner contour of the swing arm workpiece are in positioning connection. According to the new energy vehicle axle swing arm machining tool disclosed in the invention, the pedestal is used as a main body supporting frame, the swing arm outer contour positioning device is used for positioningand pressing the outer contour of a swing arm, the swing arm inner contour positioning device is used for positioning and pressing the inner contour of the swing arm, and therefore the six degrees offreedom of the swing arm workpiece can be restrained, the whole set of tool can achieve one-time clamping machining, the inner and outer contour positioning error clearance of the swing arm can be adjusted and compensated for through the elastic auxiliary supporting assembly, and the machining precision is high; and meanwhile, the advantages of being high in machining efficiency and reliable in structure are achieved, and the new energy vehicle axle swing arm machining tool can be applied and popularized easily.

Description

Technical field [0001] The invention relates to a tool for processing axle components, in particular to a tool for processing a swing arm of a new energy axle. Background technique [0002] In recent years, the development trend of new energy vehicles has continued to expand. With the rapid development of new energy technologies for automobiles, 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 operational stability can meet the development requirements of urban public transport. The independent suspension rear axle system is that the wheels on each side are separately elastically suspended under the frame or the body, and the disconnected swing arm is used to form an independent single-sided support suspension. Not only the left and right wheels beat independently, it greatly reduces The bouncing and tilti...

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
