Abstract

The invention discloses a pneumatic spot welding machine. The pneumatic spot welding machine comprises an electric welding machine box, wherein an inner cavity of the electric welding machine box is hollow, a transformer is fixedly connected to the inner side wall of one side of the electric welding machine box, a heat dissipation tube which is spirally distributed is fixedly arranged on the innerside wall of the electric welding machine box, an electric control box, a water pump, a liquid cooling head filled with cooling liquid, a heat dissipation fan and a liquid cooling gate are sequentially connected to the outer side wall of one side of the electric welding machine box in the vertical direction, the end portion of the heat dissipation tube penetrates through the inner side wall of the electric welding machine box and communicates with the liquid cooling gate, the top of the liquid cooling gate is in contact connection with the heat dissipation fan, a liquid inlet pipe and a liquid outlet pipe are connected between the liquid cooling gate and the liquid cooling head, and the outer side wall of one side, far away from the electric control box, of the electric welding machine box is sequentially connected with an upper electrode arm and a lower electrode arm which are transversely placed in the vertical direction. The pneumatic spot welding machine is simple in structure, convenient to operate and capable of carrying out buffering and pressure monitoring when a welding part is tightly pressed; and the protection function to the welding part is improved, and meanwhile, the heat dissipation performance of the spot welding machine is improved, and the working stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of spot welding equipment, in particular to a pneumatic spot welding machine. Background technique [0002] The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other. Instantaneous thermal fusion is formed at the two contact resistance points, and the welding current flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece to be welded. According to the purpose of spot welding, there are universal type and special type; according to the number of welding points welded at the same time, there are single-point, double-point, and multi-point; according to the con...
