Sectional type concentricity correcting device for axle housing

Abstract

The invention relates to the technical field of automobile processing equipment, and in particular relates to a sectional type concentricity correcting device for an axle housing. The device comprises a rack which is fixedly connected with a workbench; two axle housing brackets which are respectively used for supporting one end of the axel housing are arranged at the workbench; two hydraulic oil cylinders are arranged above the workbench and positioned between the two axle housing brackets; pressing dies for vertically downwards pressing the axle housing are connected to top rods of the hydraulic oil cylinders; the hydraulic oil cylinders are fixedly connected with the rack; the rack is connected with two electronic concentricity measuring instruments for measuring the concentricity of two ends of the axle housing; the output ends of the electronic concentricity measuring instruments are electrically connected with controllers of hydraulic oil cylinders. The device is scientific in structure; the axle housing is supported through the axle housing brackets; the electronic concentricity measuring instruments are used for detecting the axle housing and sending the detection result to the controllers of the hydraulic oil cylinders, the controllers calculate and then press the pressing dies to downwards move a certain distance to press the axle housing, so as to correct the concentricity.

Description

technical field [0001] The invention relates to the technical field of automobile processing equipment, in particular to a segmented axle housing concentricity correction device. Background technique [0002] The axle housing is one of the main components of the vehicle driving system. It is used to install the main reducer, differential, half shaft, wheel hub and suspension, etc. Its main function is to support and protect the main reducer, differential and half shaft, etc. . The drive axle housing should have sufficient strength and rigidity, low mass, and facilitate the disassembly and adjustment of the main reducer. Drive axle housings can be divided into two types: integral axle housings and segmented axle housings structurally. Integral axle housings are generally formed by casting, while segmented axle housings are formed by welding, also known as stamped and welded axle housings and tailor-welded axle housings. Due to the advantages of fatigue resistance and high ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the technical characteristics of the segmented axle housing, it also has some disadvantages. It adopts a segmented structure, and then welds the parts together, which makes it difficult to ensure the concentricity of the two ends of the axle housing, especially due to the deformation during welding, which makes it necessary to Correct the concentricity in the later stage

In the prior art, two presses are generally used to work at the same time, and the two ends of the axle housing are respectively placed on the workbenches of the two presses, fixed, the concentricity is checked, and the press is used for correction, which is labor-intensive. The whole process requires manual operation. When controlling the press for calibration, it needs repeated calibrations to meet the requirements, and the efficiency is very low.
