Description

Technical Field

[0001] The utility model belongs to the technical field of metal welding, and in particular relates to a small automatic welding device. Background Art

[0002] Welding is a common metal process that uses high temperature to melt materials and fix two parts together. For some processes with high welding requirements, multiple welding points are required between the two parts, and welding is repeated. In order to save manpower, a variety of automatic welding devices have appeared on the market to automatically weld the joints of workpieces.

[0003] For example, the patent application with the prior art announcement number CN 218051115 U sets a plurality of welding stations on the workbench, thereby ensuring that the welding device can install the workpiece at the same time during the welding process. At the same time, the welder is driven by the motor 1 and the motor 2 to move in multiple directions, thereby automatically welding the workpiece and improving the work efficiency. A rotating mechanism is set, so that the welder can rotate 180 degrees under the drive of the hydraulic telescopic rod 1, and the welder can be rotated to the other end to continue welding after the welding is completed at the station at one end of the workbench, thereby saving the time of replacing the workpiece and improving the welding efficiency. A placing mechanism is set, thereby realizing the fixation of the workpiece to be welded, and the workpiece to be welded can be clamped and fixed under the drive of the threaded rod 3, which can ensure the stability of the workpiece to be welded during the welding process and the quality of the workpiece after welding. However, in the use of this technology, it is not convenient to block the workbench between the human body, which can easily cause the laser generated during welding to cause certain damage to the skin and eyes, making it a safety hazard. For this reason, we propose a small automatic welding device. Summary of the invention
