Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a cab frame welding tool. Background Art

[0002] Tractors, as important mechanical equipment, have extremely important applications in agriculture. During production, the cab frame of a tractor is fixed using a welding device. The top of the tractor cab is located relatively high, and when welding the cab top, workers need to climb up to a high place to perform the welding. Prior art publication number CN214921703U proposes a welding device for a tractor cab shell, which includes an L-shaped mounting plate and a welding tank. The lower end of the welding tank is fixedly mounted on the side wall of the L-shaped mounting plate via a bottom plate. The upper end surface of the welding tank is provided with a welding mechanism. A lifting plate is slidably connected to the side wall of the L-shaped mounting plate. The upper end surface of the lifting plate is provided with a shock-absorbing mechanism. The lower end surface of the lifting plate is provided with a limit groove. A limit rod is fixedly mounted in the limit groove, and a sliding sleeve is slidably sleeved on the limit rod. In this utility model, the servo motor drives the screw to rotate through the output end, which drives the screw block to move upward, thereby causing the right end of the rotating plate to rotate upward, lifting the lifting plate upward, so that the lifting plate and the pedal move upward together, thereby raising the welder to facilitate welding on the top of the cab, avoiding the welder from climbing high to weld, and reducing the risk factor for the welder. However, the pedal area is small, the worker's working range is small, and it is easy to step on empty space, which is very dangerous. Utility Model Content
