Technical Field
[0001] The utility model relates to the technical field of welding devices, in particular to a welding device for a rear frame of a loader. Background Art
[0002] A loader is an earth-moving construction machine widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used for shoveling loose materials such as soil, sand, lime, and coal. It can also perform light shoveling and excavation of ore, hard soil, etc. By replacing different auxiliary working devices, it can also perform bulldozing, lifting, and loading and unloading of other materials such as wood. During the production process of the loader, its rear frame needs to be welded.
[0003] Traditional welding is mostly done manually, which has low work efficiency and affects the progress of subsequent processing.

The laser welder is installed above the workbench. Servo electric cylinders are symmetrically installed on both sides above the workbench. A fixed plate is fixedly installed at the end of the servo electric cylinder. An auxiliary support moving mechanism is arranged above the workbench. The auxiliary support moving mechanism includes a bracket, a boss and a roller. A bracket is symmetrically fixedly installed above the workbench near the laser welder, and a circular opening is arranged in the middle of the bracket. Bosses are symmetrically fixedly installed on both sides above the workbench, and an arc groove is arranged above the boss corresponding to the circular opening. The utility model uses the auxiliary support moving mechanism, and the roller rotates with the movement of the steel pipe, which reduces the friction between the steel pipe and the boss and the bracket, making it easy to move and reducing the difficulty of positioning the steel pipe.
