Abstract

The invention relates arc welding robot making. It mainly comprises the universal joint, connecting shaft, small gear, big gear, RV decelerator, rear end cover installed on the elbow of the robot, servogenerator installed on the rear end cover, motor output shaft connected to the universal joint, whose output connected to the connecting shaft, small gear installed on the connection shaft, big gear and RV decelerator fixed in bolt connection, positioning with the central pin, through the gear drive providing power to the RV decelerator. It is scientific, reasonable, reliable, stable and highly efficient.

Description

technical field [0001] The invention relates to the field of arc welding robot manufacturing, in particular to a rotary motion transmission device of an arc welding robot shaft. Background technique [0002] At present, the arc welding robot system has been widely used in automobiles, motorcycles, construction machinery, bridges, and steel structure buildings by virtue of its high-precision sensing technology and optimized robot system configuration. The welding robots produced in all countries in the world are basically articulated robots, most of which are 6-axis; among them, the 1, 2, and 3 axes can send the end tools to different spatial positions, while the 4, 5, and 6 axes can solve the problem. Different requirements for tool attitude. Each axis of the welding robot is for rotary motion, so it is driven by a servo motor through a cycloid (RV) reducer (1-3 axis) and a harmonic reducer (4-6 axis). The existing transmission line generally adopts the motor (input end)-r...
