Automatic welding platform for double annular welding seams and welding process

Abstract

The invention discloses an automatic welding platform for double annular welding seams and a welding process. The automatic welding platform consists of a mechanical part and a control system and comprises a bed body (1), a program control system (8) and an operation box (9), wherein a modification mechanism (2) and a pneumatic feeding and discharging platform (5) are adjacent to each other and are arranged in front of the bed body (1) by a bolt respectively; a pneumatic clamp (3) is arranged on the modification mechanism (2); and the clamping station of the pneumatic clamp (3) is opposite to the feeding station of the pneumatic feeding and discharging platform (5). Two sets of welding gun control mechanisms (15 and 16) are arranged at two directions different from the modification mechanism (2) and are connected with the bed body (1); and the modification mechanism (2), the pneumatic clamp (3) and two welding guns on the two sets of welding gun control mechanisms (15 and 16) form the welding stations of double annular welding seams respectively. In the welding process, the welding current parameter of each gun can be regulated by the program respectively; and a controller can adjust the speed to display the welding power source of each part, and controls each part to be isolated from one another completely, and the reliability is high.

Description

Technical field [0001] The invention belongs to the field of welding processing equipment and relates to an automatic welding platform and a welding process for double-circular welds. In particular, it relates to a welding platform and a welding process for automatically welding the reinforcement ring of the axle housing assembly and the double-ring weld of the rear axle housing cover assembly. Background technique [0002] At present, the domestic welded axle housing assembly basically consists of a strengthening ring and a rear axle housing cover assembly. Due to the large diameter of these two rings, the welding seam is longer; the prior art equipment uses a single gun for welding at a 45° angle. The workpiece is placed at an angle of 45°, and the inner hole of the reinforcing ring and the inner hole of the shell cover are tightened on the platform, and then welding is carried out. It is necessary to strengthen the ring ring welding machine and the rear axle housing cover asse...
