Welding machine with fixing device for truss production

Abstract

The invention discloses a welding machine with a fixing device for truss production in the technical field of truss welding. A base is included, the two sides of the top end of the base are fixedly connected with fixing blocks, the two fixing blocks are rotatably connected with first mechanical arms, and the first mechanical arms are rotatably connected with second mechanical arms through connecting rods. The two second mechanical arms are fixedly connected with rotary tables, the bottom ends of the rotary tables are connected with bolts, the heads of the bolts are movably fixed to the rotary tables, the bolts penetrate through the second mechanical arms and extend to the outside to be arranged as free rotating ends, the top ends of the rotary tables are rotationally connected with rotating devices, and the top ends of the rotating devices are connected with connecting blocks in a clamped mode. Welding guns are fixedly connected to the top ends of the connecting blocks, and a truss is arranged on the top of an arranging frame. The device is simple in structure, the positions of the welding guns can be flexibly adjusted while the welding guns can be fixed, the welding quality is improved, meanwhile, a smoke suction device is further arranged, smoke dust can be sucked away immediately, and the quality of the working environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of truss welding, in particular to a welding machine for truss production with a fixing device. Background technique [0002] A truss is a structure composed of bars connected by hinges at both ends to bear tension or pressure. The truss is mainly composed of a plurality of triangular frames, which can be connected by welding, but will be damaged during the welding process. The occurrence of welding fumes seriously affects the physical safety of employees. The welding torch is generally fixed and difficult to adjust flexibly. A slight welding error will affect the welding quality. Therefore, we propose a welding machine for truss production with a fixing device. Contents of the invention [0003] The object of the present invention is to provide a welding machine for truss production with a fixing device, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to...
