Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an automatic electrode welding device. Background Art

[0002] At present, shielded metal arc welding mainly adopts a welder holding a welding torch to clamp an electrode for welding. The welding equipment is simple and the operation is convenient, so it is widely used. However, in order to obtain high-quality welds, this method requires a high level of operation skills for welders.

[0003] Most of the existing welding robots or automatic welding equipment use welding wires to achieve welding and cannot adapt to automatic electrode welding. The main reasons are as follows: First, the welding wire can be bent and continuously fed, while the electrodes are fed one by one, which increases the difficulty of replacing the electrodes in the equipment and affects the welding efficiency; second, during the welding process, the control of the electrode by the welder is greatly affected by humans, and it is impossible to ensure the welding quality and consistency.

[0004] Therefore, it is necessary to develop an automatic electrode welding device to improve the problems existing in the prior art. Summary of the Utility Model

The connecting block is rotatably connected to a connecting plate. An electric gripper is arranged on the connecting plate. Symmetrically arranged gripper blocks are installed on the electric gripper. The electric gripper is used to control the gripper blocks to clamp and loosen.

The output shaft of the motor is threadedly connected to a feeding screw, and the feeding screw is connected to a feeding plate. The feeding plate is located in the L-shaped groove of the base and is used to push the electrode to move.

[0010] More preferably, the electrode conveying assembly further includes a limit sensor disposed on the base. The limit sensor is used to detect the position of the feeding plate.
