Automatic welding machine for automobile shock absorber cover

Abstract

The invention discloses an automatic welding machine for an automobile shock absorber cover; a welding machine supporting plate is mounted on a welding blocking machine bottom electrode; a servo motor fixing bracket is connected with the lower surface of the welding machine supporting plate; an electrode heat dissipation block is mounted on the welding machine supporting plate; an electrode rotary tyre is mounted on the electrode heat dissipation block; a welding lower electrode is mounted on the electrode rotary tyre; a center hole is formed in the welding machine supporting plate, the electrode heat dissipation block, the electrode rotary tyre and the welding lower electrode in a penetrating manner; a workpiece fixing ring is arranged in the upper end of the center hole; the lower end of the workpiece fixing ring is connected with a connecting flange; a welding rotating shaft is connected with the lower side of the connecting flange; the lower end of the welding rotating shaft penetrates through the center hole of the welding machine supporting plate; a tooth type belt wheel is mounted at the lower end of the welding rotating shaft; a tooth type belt wheel on a servo electrode is connected with the tooth type belt wheel at the lower end of the welding rotating shaft through a tooth type belt; casting die claw mechanisms are mounted on the outer sides of the electrode rotary tyre. The welding machine can carry out one time card mounting and continuous welding, the work efficiency is improved, the labor intensity of operation workers is relieved, the workpiece has no difference after being welded, and the production efficiency is one workpiece per 15 seconds.

Description

technical field [0001] The invention belongs to automatic welding equipment for mechanical products, in particular to an automatic welding machine for automobile shock absorber covers. Background technique [0002] There are two processes for welding automobile shock absorber covers. One is that there are bumps on the shock absorber cover. When welding, the two parts are welded together by bump welding. The other process is single-point resistance welding. These two processes Each has its advantages and disadvantages. The first type of welding requires the upper and lower electrodes to be relatively flat, and the adjustment accuracy of the tooling welding plane is high. During welding, the power requirements of the welding machine tool are large, and the instantaneous impulse of the power grid is large. After welding, the welding force of each point is inconsistent. The second welding process is point-by-point welding. The power requirement of the welding machine is small, a...

[0002] There are two processes for welding automobile shock absorber covers. One is that there are bumps on the shock absorber cover. When welding, the two parts are welded together by bump welding. The other process is single-point resistance welding. These two processes Each has its advantages and disadvantages. The first type of welding requires the upper and lower electrodes to be relatively flat, and the adjustment accuracy of the tooling welding plane is high. During welding, the power requirements of the welding machine tool are large, and the instantaneous impulse of the power grid is large. After welding, the welding force of each point is inconsistent.

The second welding process is point-by-point welding. The power requirement of the welding machine is small, and the welding force of each point is even. The process generally needs to be welded 6 times, and the welding efficiency is significantly reduced. Manually rotating the workpiece results in uneven distribution of the 6 solder joints, which affects the appearance of the workpiece.
