Racing automobile frame welding jig

Abstract

The invention provides a racing automobile frame welding jig which comprises a platform. Inverted T-shaped grooves are formed in the platform. Horizontal 4040 aluminum profiles are arranged on the faces of the inverted T-shaped grooves of the platform. The two ends of each horizontal 4040 aluminum profile are fixedly connected with the platform through T-shaped fixing clamping plates respectively. L-shaped corner joint plates are oppositely arranged on each horizontal 4040 aluminum profile. A vertical 4040 aluminum profile is vertically clamped between every two opposite L-shaped corner joint plates. An arc-shaped groove fixing clamping plate is arranged on one vertical 4040 aluminum profile and is composed of an arc-shaped groove fixing plate and U-shaped bolts. In the use process, a frame steel pipe is clamped and fixed through the arc-shaped groove fixing clamping plate. By means of the jig, all parts of a frame can be fixed and welded independently, overall welding is conducted after residual stress is eliminated, and therefore the stability of the frame is ensured, and the racing automobile machining and manufacturing are smoothly achieved; meanwhile, all the components of the jig are low in price, and the jig is convenient to detach, capable of being repeatedly used, long in service life and capable of greatly reducing the competition cost.

Description

technical field [0001] The invention relates to a fixture used for welding the frame of a Formula Student car racing car, belonging to the field of automobile tooling fixtures. Background technique [0002] In recent years, more and more colleges and universities have begun to form their own formula racing teams. However, due to a late start and lack of experience, there are many problems in frame processing and production, especially frame construction and gap welding. [0003] Existing formula racing car frames are mostly built by traditional welding methods. The operation process is cumbersome, time-consuming and labor-intensive, and it is difficult to ensure that the clamping fixture is tight, resulting in low welding accuracy of the frame, and the resulting residual stress causes serious deformation of the frame and increases manufacturing costs. Contents of the invention [0004] In order to improve the welding precision of the vehicle frame, reduce the welding resi...
