Abstract

The invention discloses a same-side multi-head resistance welding machine for a frame and a skin. The same-side multi-head resistance welding machine comprises a shell, a welding part and a lower cantilever assembly, wherein the welding part comprises a plurality of electrode tips; the lower cantilever assembly comprises a bearing platform; the welding part is arranged on the upper part of the shell, and the lower cantilever assembly is arranged at the lower part of the shell; the plurality of electrode tips are all arranged right above the bearing platform; and the welding part comprises a first mounting seat, a sliding groove plate, a first air cylinder seat, first air cylinders, first piston arms, an upper electrode block, a lower electrode block, middle electrode blocks, electrode armsand the electrode tips. The same-side multi-head resistance welding machine has the advantages of same side multi-head welding, the electrode tips are arranged on the upper part, no electrode heads is arranged at the lower part, the lower part is provided with the bearing platform for bearing and supporting, single-side welding is carried out only on the upper part, a welding spot is formed onlyon the single side, and the welding spot cannot be formed on the back surface, so that a grinding step after welding is finished is not needed, and the time and the labor are saved.

Description

Technical field: [0001] The invention relates to the technical field of resistance welding machines, in particular to a multi-head resistance welding machine on the same side of a frame and skin. Background technique: [0002] Resistance welding refers to the method of using the resistance heat generated by the current passing through the weldment at the contact point as the heat source to locally heat the workpiece and simultaneously pressurize it for welding. When welding, no filler metal is required, the productivity is high, the deformation of the weldment is small, and it is easy to realize automation. [0003] The welding of the pallet box frame and the skin of the existing centralized box is usually welded by the second welding machine. After the welding is completed, due to the large heat-affected zone, it is very inconvenient to polish. Now, the welding method of resistance welding is gradually applied. For example, domestic pallet box welding has been widely used. ...
