Abstract

The invention discloses a six-freedom-degree controllable mechanism type welding robot. One end of a stand column is connected with a vehicle body through a rotation pair; the other end of the stand column is connected with one end of a main arm and a first connection end of a first rocker arm; a second connection end of the first rocker arm is connected with one end of a first connection rod; the other end of the first connection rod is connected with a second connection end of a second rocker arm; a first connection end of the second rocker arm is connected with the other end of the main arm; a third connection end of the second rocker arm is connected with one end of a second connection rod; the other end of the second connection rod is connected with a third connection end of the first rocker arm; one end of a third connection rod is connected with a fourth connection end of the second rocker arm; the other end of the third connection rod is connected with one end of a fourth connection rod; the other end of the fourth connection rod is connected with a tail end welding actuator; one end of a connection block is connected with the stand column through a fixed pair; the other end of the connection block is connected with a fifth connection rod; the fifth connection rod, a sixth connection rod, a seventh connection rod and the second connection end of the main arm are sequentially connected with one another. The six-freedom-degree controllable mechanism type welding robot has the advantages of large working space, high rigidity, high bearing capability and high execution accuracy.

Description

technical field [0001] The invention relates to the field of robots, in particular to a six-degree-of-freedom controllable mechanism welding robot. Background technique [0002] Compared with traditional series robots, parallel robots have no cumulative error, high precision, compact structure, large carrying capacity, high rigidity and end welding actuators. Small inertia and other characteristics, the driving device can be placed on the fixed platform or close to the fixed platform, so that the moving part is light in weight, high in speed, and good in dynamic response; but the obvious disadvantages of parallel robots are small working space and complex structure. Existing manipulators with partial closed chains such as MOTOMAN-K10 in engineering do not solve the problems of industrial robots. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a six-degree-of-freedom controllable mechanism welding robot, which so...
