Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and particularly relates to a gas shielded welding device. Background Art

[0002] During the welding process of silicon carbide, in order to improve the quality of the weld seam, the gas shielded welding method is usually adopted. In order to facilitate the gas shielded welding of silicon carbide, workers usually use a gas shielded welding device. The existing gas shielded welding device usually consists of a moving base, a gas shielded welding machine and a welding head. During use, the gas shielded welding machine is moved to a specified position through the moving base, and then the gas shielded welding machine is started to adjust the flow rate of the shielding gas and the welding parameters. Subsequently, the welding area of the silicon carbide is welded through the welding head.

[0003] For example: The utility model with the application number CN202020276221.2 discloses a gas shielded welding device. Specifically, limit blocks are fixedly connected to the four end points at the lower part of the base. Two limit blocks are arranged in parallel at each end point. The rotating shaft passes through the bottom of the limit block and is rotatably connected to the limit plate. The roller is located between the two limit blocks and is slidably connected to the limit block. Four rotating mechanisms are arranged at the four end points of the base respectively. The support rod is located at one end of the middle part of the base and is hinged to the base. Two long rods are arranged in parallel. One end of the long rod is fixedly connected to the support rod. The cross bar is arranged in parallel with the support rod, and both ends of the cross bar are fixedly connected to the end of the long rod far from the support rod. The support rod, the long rod and the cross bar form a rectangular frame. Four fixing plates are vertically arranged at the bottoms of the four end points of the frame respectively and are fixedly connected to the frame. The stepping mechanism is located in the middle of the upper end of the cross bar and is fixedly connected to the cross bar. By setting the stepping mechanism in the utility model, the rotation and stop of the roller are controlled to achieve a fixing effect.

[0004] However, for the current traditional gas shielded welding device, a large amount of spatter will be generated during the welding process. These spatters are easily attached to the welding head. After the welding is completed, in order to prevent the attached spatters from affecting the subsequent welding quality of the welding head, it is usually necessary for workers to regularly clean the spatters on the welding head, which increases the labor intensity of the workers and is inconvenient to use. Summary of the Utility Model

[0005] In view of this, the present utility model provides a gas shielded welding device, which has a cleaning scraper that can automatically clean the spatter on the welding head when the welding head is placed. The welding head is inserted into the placement groove, and then through a series of transmissions, the movement of the welding head will push the reset plug to move. During the process of controlling the movement of the pressing block, it will drive the connecting slide plate to move. During the movement of the connecting slide plate, it will drive the control rack to move. During the movement of the control rack, it will drive the control gear to rotate. During the rotation of the control gear, it will drive the first pulley to rotate. During the rotation of the first pulley, it will cause the second pulley to rotate through the transmission belt. During the rotation of the second pulley, it will drive the first bevel gear to rotate. During the rotation of the first bevel gear, it will drive the meshing second bevel gear to rotate. During the rotation of the second bevel gear, it will drive the transmission gear to rotate. During the rotation of the transmission gear, it will drive the hollow gear to rotate. During the rotation of the hollow gear, it will drive the cleaning scraper to rotate to clean the residual spatter on the welding head.
