Welding device and technique of axle housing assembly Y-shaped weld joint

Abstract

The invention relates to welding equipment for the Y-shaped welding seam of an axle housing body assembly and a welding technology thereof, which belong to the field of the welding processing. The welding equipment comprises a lathe bed 2, a driving machine head 3, a crossbeam assembly 4, a centralized positioning device 5, a pneumatic welding torch lifting mechanism 6, a welding torch adjusting mechanism 7, a driven machine head 8, an oscillator 9, an automatic welding controller 10, an electric control system 11 and a welding source 12, wherein, the driving machine head 3 and the driven machine head 8 are concentric, a vertical adjusting device is arranged in the centralized positioning device 5, air cylinders on the driving machine head 3, the driven machine head 8, the centralized positioning device 5 and the pneumatic welding torch lifting mechanism 6 are connected with the electric control system 11, the circuit parts of the welding source 12 and the electric control system 11 are connected to the automatic welding controller 10 through wires; the ways of manual adjustment and automatic welding are adopted, and the welding equipment is provided with twenty sets of welding sequences; the descending height of the lifting mechanism or the welding torch in the welding process is preset, therefore, the welding current parameters in each procedure can be respectively adjusted in the welding process.

Description

technical field [0001] The invention belongs to the field of welding processing, and relates to welding equipment and a welding process for a Y-shaped welding seam of an axle housing body assembly. Background technique [0002] The Y-shaped weld seam of the axle housing body assembly is long, and the welding labor intensity is high. There are two existing solutions: one is to manually weld the Y-shaped weld seam of the axle housing body assembly. Due to human factors, the quality of seams fluctuates greatly, which cannot meet the product quality requirements, and the labor intensity is high; the second solution is to use special mechanical welding with a single function, which has the following disadvantages: special machinery can only store one product program, When replacing products, it takes up to 45 minutes to ask for advice again; it takes up to 20 minutes to replace tooling; at the same time, the requirements for the axle housing body assembly are too high, and the st...
