Technical Field

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

[0002] An automatic welding robot is a robot system that can perform welding operations autonomously. It uses advanced computer vision and machine learning technologies to sense the requirements of welding tasks and perform welding actions under real-time control. Automatic welding robots mainly include arc welding robots, spot welding robots, and laser welding robots, which are widely used in many fields such as automobile manufacturing, electronic manufacturing, energy industry, and metal processing and manufacturing. They can not only accurately complete complex welding tasks and improve production efficiency, but also ensure welding quality and consistency. In addition, automatic welding robots are usually equipped with multi-degree-of-freedom robotic arm structures with good motion flexibility and accuracy. The joints on the robotic arm are driven by electric motors, and the combination of connecting rods and connectors enables the robotic arm to achieve accurate posture and position adjustment in three-dimensional space. At the same time, they are also equipped with sensor systems, such as visual sensors or laser sensors, for detecting and locating the workpieces to be welded, accurate positioning and welding path planning. In general, automatic welding robots play an increasingly important role in the development of industrial automation and intelligent manufacturing. With the continuous advancement of technology, they will be applied in more fields to promote the sustainable development of modern manufacturing.

The number of the plug columns 5 is two, and the two plug columns 5 are symmetrically arranged inside the fixing seat 2. A plug groove 6 is opened on the top of the outer side of the plug connector 3, and the plug column 5 is clearance-matched with the plug groove 6. A fixing mechanism is fixedly connected to one side of the plug column 5 for pushing the plug column 5 into the plug groove 6 to lock and fix the plug connector 3 and the fixing seat 2, and the plug column 5 can slide along the slope of the conically arranged plug connector 3.

[0025] The fixing mechanism comprises a fixing plate 701 . A sliding groove 702 is provided inside the fixing seat 2 . The fixing plate 701 is slidably connected to the sliding groove 702 . A connecting plate 703 is fixedly connected to one side of the fixing plate 701 .

[0026] One end of the connecting plate 703 penetrates to the outside of the fixing seat 2 , and the end of the connecting plate 703 is fixedly connected with a handle 704 , which contacts the fixing seat 2 .

[0027] The top and bottom of one side of the fixed plate 701 are both fixedly connected with a first spring 705 , and one end of the first spring 705 is fixedly connected to the inner wall of the sliding groove 702 .

[0028] The working principle of this embodiment is as follows: when installing the welding gun 4, the welding gun 4 is moved so that the plug connector 3 is opposite to the fixing seat 2 at the end of the robot arm body 1, and then the welding gun 4 is rotated so that the plug connector 3 at its end is installed in the fixing seat 2 through a threaded connection. When the threaded connection between the welding gun 4 and the fixing seat 2 is completed, the plug-in groove 6 on the outside of the plug connector 3 contacts the plug-in column 5 located on the inside of the fixing seat 2. At this time, the fixing plate 701 pushes the plug-in column 5 into the plug-in groove 6 under the elastic force of the first spring 705. The fixing seat 2 and the plug connector 3 can be connected through the plug-in column 5. The threaded connection itself has a high connection strength.
