Automobile part spot-welding robot with welding head convenient to replace

Abstract

The invention relates to the technical field of automobile part spot-welding robots, in particular to an automobile part spot-welding robot with a welding head convenient to replace. The automobile part spot-welding robot comprises a base, a protective device, a cleaning device and a replacing device; the protective device is arranged at the left side of the top end of the base; the spot-welding robot is fixedly connected to the center of the top end of the base; a controller is fixedly connected to the left end of the outer side of the spot-welding robot; a supporting base is fixedly connected to the right end of the outer side of the spot-welding robot; and a spot-welding connector of the spot-welding robot penetrates through the supporting base. In the automobile part spot-welding robotprovided by the invention, a third gear and a fifth gear are arranged; the arrangement cooperates with meshing connection of a fourth gear and the fifth gear, meshing connection of the third gear, afirst gear and a second gear and rotary connection of a rotating column and the base, when the welding head of the spot-welding robot is aged and damaged, rapid and automatic replacement of the welding head can be achieved, and therefore the machining efficiency of automobile parts is guaranteed.

Description

technical field [0001] The invention relates to the technical field of spot welding robots for auto parts, in particular to a spot welding robot for auto parts which is convenient for replacing welding heads. Background technique [0002] The spot welding robot is composed of the robot body, computer control system, teaching box and spot welding welding system. In order to meet the working requirements of flexible movements, the basic design of jointed industrial robots is usually used for electric welding robots, which generally have six degrees of freedom. : Waist rotation, arm rotation, forearm rotation, wrist rotation, wrist swing and wrist twist, the driving methods are hydraulic drive and electric drive. With the continuous development of society, there are more and more applications for spot welding robots , but some spot welding robots for auto parts processing will have some defects when they are used. Therefore, there is an increasing demand for a spot welding robo...

AI Technical Summary

Problems solved by technology

[0003] In the field of spot welding robots, when some of the spot welding robots currently used for auto parts processing are in use, when the welding heads are aging or damaged, the rapid and automatic replacement of the welding heads cannot be realized, which greatly reduces the cost of auto parts. Processing efficiency, and when some auto parts spot welding robots are in use, they cannot clean the dust, foreign matter and oil stains on the spot welding parts of the workpiece well, which will affect the normal use of the spot welding robots, thus affecting the parts. Normal processing reduces the processing quality of parts, and some spot welding robots for auto parts processing cannot protect the spot welding parts of the spot welding robot well when the spot welding work is completed, which speeds up the spot welding robot. The aging speed of spot welding parts, and the phenomenon of collision damage of spot welding parts is prone to occur, which shortens the service life of spot welding parts. Therefore, in view of the above problems, a spot welding robot for auto parts that is easy to replace the welding head is proposed
