Automatic welding device for automobile rear axle housing

Abstract

The invention discloses an automatic welding device and method for an automobile rear axle housing. The welding device is characterized in that a rotary clamping mechanism comprises an oblique wedge,an oblique wedge base, first ejection pins and second ejection pins, the first ejection pins are arranged in first sliding grooves of the oblique wedge base in a symmetrical 180-degree mode, the second ejection pins are arranged in second sliding grooves of the oblique wedge base in a symmetrical 180-degree mode, an 90-degree angle is formed between the first sliding grooves and the second slidinggrooves, the oblique wedge is matched with the first ends of the first ejection pins and the first ends of the second ejection pins, and jacking discs are horizontally arranged at the two ends of theupper portion of a rotary clamping mechanism. The welding method comprises the steps of axle housing cover and reinforcing ring spot welding after positioning, horizontal ring welding seam welding and vertical ring welding seam welding. According to the automatic welding device and method for the automobile rear axle housing, welding of six welding seams is achieved on one device, therefore, theequipment occupation area is decreased, and the equipment cost is reduced; the intermediate part carrying process is omitted, and the welding efficiency can be greatly improved; and a welding gun onlyneeds to have a telescopic function and does not need to conduct welding seam tracing, and the automatic welding device has the advantage of being simple in structure.

Description

technical field [0001] The invention belongs to the technical field of automatic welding, and in particular relates to an automatic welding device and method for an automobile rear axle housing. Background technique [0002] Among the industrial robots in the world, 50% of them are used in different welding fields. There are two basic methods of welding robots: electric welding and arc welding. The main job of the welding robot is to replace the industrial robot that the worker manually welds in the welding field. Part of this type of robot is a dedicated robot, that is, a special robot that is suitable for working in a certain environment. Most welding robots are composed of traditional industrial robots with welders installed. In the aspect of welding processing, workers are required to have sufficient proficiency in welding tasks and have a lot of practical experience. On the other hand, welding work is a kind of work with harsh working environment, a lot of smoke and du...

Problems solved by technology

The existing technology is to first weld the transverse girth weld on the welding workbench, and carry out the welding of the longitudinal girth weld after transferring the welded parts to the longitudinal girth weld welding table. There are parts handling and positioning in the middle. Affects welding efficiency; at the same time, the two sets of welding workbenches also have the defects of large floor area and high equipment investment
