Machine special for automatic welding of baseboard and welding method

Abstract

The invention discloses a machine special for automatic welding of a baseboard. The machine comprises a platform and a machine frame, a welding post and a correcting post are arranged on the platform, the machine further comprises a supporting feeding mechanism used for moving shaft bodies to different posts, a first fixed tailstock and a first moving tailstock are arranged on the correcting post, a second fixed tailstock and a second moving tailstock are arranged on the welding post, sliding rails are arranged on two sides of the machine frame, each sliding rail is provided with welding equipment, and a pivot device used for driving the shaft bodies to rotate is further arranged on the welding post. Due to the fact that correcting and welding are divided, corrected shaft bodies are conveyed to the welding post through a conveying belt, production efficiency is improved by one time. The process of correcting is conducted automatically, a worker needs only to operate a point welding machine and click a welding command, the inherent defect of manual locating is overcome, and therefore the machine special for automatic welding of the baseboard has the advantages of being reasonable and accurate in clamping and locating and capable of guaranteeing dimensional tolerance of the shaft bodies, aligning a welding gun automatically, overcoming the phenomenon of partial welding and improving welding assembling quality greatly.

Description

technical field [0001] The invention relates to a welding processing device for axle parts, more specifically, it relates to a special automatic welding machine for bottom plate and its welding method. Background technique [0002] At present, while the automobile industry is developing rapidly in China, it also drives the development of the auto parts mold / equipment industry. The axle of the semi-trailer is composed of axle body, bearing, brake base plate, wheel hub, hub cover, oil seal, camshaft, adjustment arm, brake drum and brake shoe assembly, wherein the base plate is fixed on the bare shaft by welding. On the body, the welding of the bottom plate and the axle body is a special process of axle manufacturing, and it is a key process to meet the performance of the axle. The quality of the welding directly affects the fatigue life of the axle. At present, the welding process of the bottom plate is as follows: first, the bottom plate is inserted into the shaft body with ...

AI Technical Summary

Problems solved by technology

At present, the bottom plate welding equipment can be equipped with a spot welding machine on the ordinary automatic welding equipment. However, because the current welding is manually operated by a single post, the calibration and welding are completed on the same machine, and the workers need to wait for the automatic welding to be completed. Welding of the next axle, the production efficiency is relatively low

The assembly of the bottom plate adopts sleeve positioning, and each time the welding wire needs to be manually aligned before welding. The operation is very cumbersome, and it is easy to affect the correct positioning due to human factors, thereby affecting the welding quality and making it difficult to ensure the life of the axle.
