Welding device for longitudinal beam of underframe of carriage of dumper truck

Abstract

A welding device for a longitudinal beam of an underframe of a carriage of a dumper truck is used for changing the welding mode of the longitudinal beam of the underframe of the carriage. The welding device of the longitudinal beam of the underframe of the carriage of the dumper truck comprises an air cylinder used to tightly clamp the longitudinal beam of the underframe, a welding tractor used to weld a welding line on the longitudinal beam of the underframe, and an electric device to control the moving of the welding tractor, wherein the electric device is used to protect the welding tractor to automatically move and weld. According to this arrangement, the welding mode is changed; therefore, the deformation of the welding is small, the welding line is beautiful, and the welding efficiency is improved.

Description

technical field

[0001] The invention relates to the field of automobiles, in particular to a welding device for the longitudinal beam of the underframe of a dump truck compartment. Background technique

[0002] At present, most of the longitudinal beams of the underframe of dump trucks in China are welded manually on the platform. The disadvantages of this method are that the welding skills of the workers vary greatly, the quality of the welds cannot be guaranteed, and the repair welding of the welds is time-consuming and laborious. There is no tooling to fix the size, it is easy to be deformed by heat after welding, and it is difficult to correct.

[0003] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a welding device for the longitudinal beam of the underframe of the dump truck body with an improved structure, so as to overcome the above-mentioned defects. Contents of the invention

[0004] In view of this, the object of the pr...
