Description

Technical Field

[0001] The utility model relates to the technical field of welding gun plugging and pulling positioning, in particular to a quick plugging and pulling positioning device for a mechanical arm welding gun. Background Art

[0002] The industrial robot arm is defined as "its manipulator is automatically controlled, reprogrammable, multi-purpose, and can be programmed for more than 3 axes. It can be fixed or mobile and used in industrial automation applications." The manipulator is also defined as "a machine whose mechanism is usually composed of a series of components that are hinged or relatively slid. It usually has several degrees of freedom to grab or move objects (tools or workpieces)." Therefore, the industrial robot arm may be understood as: a mechanical and electronic device with the functions of anthropomorphic arms, wrists and hands; it can move any object or tool according to the time-varying requirements of spatial posture (position and posture) to complete the operation requirements of a certain industrial production. For example, clamping welding tongs or welding guns, spot welding or arc welding of automobile or motorcycle bodies; carrying die-cast or stamped parts or components; laser cutting, spraying and assembling mechanical parts, etc. The welding robot arm can be divided into two categories: spot welding and arc welding. At the end of welding, the welding gun usually needs a positioning device to plug and unplug the head of the welding gun for positioning and protection, so as to improve the efficiency of the use of the gun head.

[0003] In the existing technology, a smoke meter plug-in connector and a smoke meter thereof with publication number: CN216201471U are proposed, which include a connecting part and a plug-in part. When in use, the plug-in part is inserted into the inside of the connecting part; the connecting part includes a connecting disk, and a connecting hole is arranged in the middle of the connecting disk; a plurality of fixed through holes are evenly distributed on the outer circumference of the connecting disk, and a marble top screw is arranged in the fixed through hole; the plug-in part includes a connecting tube, and a groove matching with the marble top screw is connected to the connecting tube, and a plug-in connector is arranged at the front end of the groove; the plug-in connector matches with the connecting hole. The smoke meter plug-in connector described in the utility model can be quickly plugged in and out, realizing the rapid installation and disassembly between the exhaust pipe and the smoke meter.

[0004] In order to solve the problem that some positioning joints are fixed and are very difficult to plug and unplug during installation and disassembly because they are fixed tightly when connected, and the joints are prone to deformation after many times, the prior art uses a rebound plug-in method to deal with it. However, the protection effect of the locator is not ideal when plugging and unplugging the positioning. During insertion, excessive force may cause fission of the locator. At the same time, excessive heat from the welding gun tip may cause damage to the inside of the locator, thereby reducing the utilization efficiency of the locator. Utility Model Content
