Automatic welding equipment for automobile frame

Abstract

The invention relates to the technical field of automatic welding, and in particular to automatic welding equipment for an automobile frame. The equipment comprises a wing plate positioning clamping mechanism, a first linear displacement mechanism, a second linear displacement mechanism, a lifting mechanism, an overturning driving mechanism, an overturning support frame, a vertical overturning clamping mechanism, a horizontal overturning clamping mechanism, solder mechanisms and a controller, wherein the first linear displacement mechanism and the second linear displacement mechanism are arranged on the wing plate positioning clamping mechanism; the first linear displacement mechanism and the second linear displacement mechanism have a same structure and only have opposite directions; thelifting mechanism is fixedly arranged on the first linear displacement mechanism and the second linear displacement mechanism; the overturning driving mechanism is fixedly arranged on the lifting mechanism; the overturning support frame is fixedly connected with an end part of the overturning driving mechanism; the vertical overturning clamping mechanism and the horizontal overturning clamping mechanism are arranged on the overturning support frame; and the solder mechanisms are uniformly arranged in gaps among all components of the wing plate positioning clamping mechanism. The equipment hasthe advantages of more accurate positioning, high welding efficiency and wide application range.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to an automatic welding equipment for automobile girders. Background technique [0002] The modern automotive industry has higher and higher requirements for lightweight, safety, exhaust emissions, cost control and fuel economy, which drives the automotive industry to use high-strength steel plates and some high-strength and lightweight materials. The car frame is an important load-bearing part of the car. According to statistics, the mass of the car body accounts for about 40% to 60% of the car's own quality. The lightweight structure of the car is of great significance to the energy saving and environmental protection of the car. The H-shaped girder composed of high-strength steel plates instead of traditional steel plates can reduce the weight of the frame. The H-shaped girder is welded by web and wing plates. [0003] In this welding process, the web and the flange sh...

Problems solved by technology

The disadvantage of manual spot welding is that its quality depends on the skill level of the welder and the performance state during operation. The welding quality is unstable, the labor intensity of the workers is high, and the smoke and high temperature generated during welding will damage the cornea and skin of the human body.

[0006] However, there are several problems in the above scheme. One is that the positioning of the H-shaped steel is not enough when it is transported to the reverse welding area, and there will be a problem of offset.

One is that the fixation during the flipping process is not enough, there will be problems of side slipping or even the wing plate falling from the web
