A first sliding rail and a second sliding rail are arranged on the first supporting table and the second supporting table respectively. The workpiece fixing frame is mounted on the first sliding rail and the second sliding rail and driven by the first driving mechanism. A third sliding rail and a fourth sliding rail are arranged on the first crossbeam and the second crossbeam respectively. A first sliding table and a second sliding table are mounted on the third sliding rail and the fourth sliding rail respectively and are driven by the second driving mechanism and the third driving mechanism respectively. The first telescopic air cylinder and the second telescopic air cylinder are mounted on the first sliding table and the second sliding table respectively. The first welding gun and the second welding gun are connected with the first telescopic air cylinder and the second telescopic air cylinder respectively.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a fast welding device for a mast of a forklift. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. [0003] At present, in the field of forklift manufacturing, during the welding process of the forklift mast, one side welding must be performed first, and then turn to the other side for welding. The welding positioning is difficult, easy to weld deformation, poor welding effect, low welding efficiency and high cost. Contents of the invention [0004] Based on the technical problems in the above-mentioned background technology, the present invention proposes a fast welding device for a forklift mast to improve welding effect and welding efficiency. [0005] The invention provides a fast welding device for a forklift...
