Anti-collision device for welding robot

Abstract

The invention discloses an anti-collision device for welding a robot. The device comprises an upper shell, a lower shell, a connection spring ring, an upper contact reed, a lower contact reed and positioning steel balls. The two axial ends of the connection spring ring are in threaded connection with the interiors of axial cavities of the upper shell and the lower shell, the upper contact reed isof an annular structure and is arranged on the connection end face of the upper shell through multiple connection points, the opposite surfaces of the upper contact reed and the lower contact reed areprovided with contact bumping points, the lower contact reed is of an annular structure, the overall lower contact reed is fixedly arranged on the connection end face of the lower shell, and under the normal state, the upper contact reed and the lower contact reed are in contact. The anti-collision device is installed between the robot and a welding gun supporting arm, in the work process of welding the robot, when a welding gun accidentally collides with a workpiece, equipment is prevented from being damaged, the perfect equipment is guaranteed, and the anti-collision device has an all-direction anti-collision function and is high in sensitivity.

Description

technical field [0001] The invention belongs to the technical field of welding robots, and in particular relates to an anti-collision device for a welding robot. Background technique [0002] With the rapid development of my country's machinery manufacturing industry and robot technology, more and more processing is required by robots, and the movements are becoming more and more complex. Using robots to perform operations not only greatly reduces labor costs, but also replaces manual labor for dangerous operations. For example, welding connection is a commonly used connection method for metal structures of mechanical equipment. There are many uncertain factors in manual welding. Therefore, welding robots used in welding operations have been widely used. [0003] At present, the welding torch and the robot arm of the welding robot are mostly fixed and rigidly connected. When the welding torch is welding and moving, accidental collisions between the welding torch and the workp...

AI Technical Summary

Problems solved by technology

[0003] At present, the welding torch and the robot arm of the welding robot are mostly fixed and rigidly connected. When the welding torch is welding and moving, accidental collisions between the welding torch and the workpiece or equipment often occur. Such collisions may cause the welding torch to deform or damage the welding torch. It will affect the quality of the welding process, and it will cause damage to the equipment and increase the maintenance cost of the equipment.
