Suspension type spot welder with protection plate

Abstract

The invention provides a suspension type spot welder with a protection plate. The suspension type spot welder comprises a spot welder, wherein the spot welder comprises a workbench, a spot welder bracket, an upper electrode, a lower electrode, an upper protection cover and a lower protection cover, wherein the spot welder bracket comprises a support rod, a T-shaped support rod and a connection rod; a protection plate is mounted at the upper end of the workbench; an observation window is formed in the protection plate. Compared with the prior art, the suspension type spot welder with the protection plate has the beneficial effects that the upper protection cover and the lower protection cover are closed when not working, thereby preventing the dust from entering the upper electrode and the lower electrode and avoiding the danger caused by the dust in the spot welding process; a welding part is arranged at the upper end of the lower electrode and is positioned when working; a telescopic hydraulic rod is controlled to rise and fall, thereby driving the upper electrode to weld the welding part; through the protection plate on the workbench, the harm to workers during spot welding is reduced. The suspension type spot welder with the protection plate is simple in structure, convenient to operate and accurate in spot welding; the safety coefficient of production is increased.

Description

technical field [0001] The invention relates to a hanging spot welding machine with a protective plate, which belongs to the field of welding equipment. 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, without damaging the internal structure of the workpiece to be welded. [0003] At present, spot welding machines are often used for welding bolts, but the upper and lower electrodes of the current spot welding machines are not protected, which will cause a lot of dust to enter and affect the ...

AI Technical Summary

Problems solved by technology

[0003] At present, spot welding machines are often used for welding bolts, but the upper and lower electrodes of the current spot welding machines are not protected, which will cause a lot of dust to enter and affect the welding process, and the existing spot welding machines have no protective measures, which will cause people The body of the spot welding machine has a certain impact. The spot welding machine is equipped with a protective plate on the workbench and a protective cover on the upper and lower electrodes, which solves this problem, reduces the entry of dust and the harm to the worker's body, and improves the spot welding machine. safe processing factor
