Abstract

The invention discloses a multi-degree-of-freedom controllable mechanism type moving welding robot. One end of a stand column is connected with a vehicle body; the other end of the stand column is respectively connected with one end of a main arm and the first connection end of a first rocker arm; the second connection end of the first rocker arm is connected with one end of a first connecting rod; the other end of the first connecting rod is connected with the second connection end of a second rocker arm; the first connection end of the second rocker arm is connected with the other end of the main arm; the third connection end of the second rocker arm is connected with one end of a second connecting rod; the other end of the second connecting rod is connected with the third connection end of the first rocker arm; one end of a third connecting rod is connected with the fourth connection end of the second rocker arm; the other end of the third connecting rod is connected with one end of a fourth connecting rod; the other end of the fourth connecting rod is connected with a tail end welding executor; one end of a sliding block is connected with the stand column via a moving pair; the other end of the sliding block is connected with a fifth connecting rod; the fifth connecting rod, a sixth connecting rod, a seventh connecting rod and the third connection end of the main arm are successively connected. The multi-degree-of-freedom controllable mechanism type moving welding robot has the advantages of large working space, high rigidity, high bearing capability and high execution precision.

Description

technical field [0001] The invention relates to the field of robots, in particular to a multi-degree-of-freedom controllable mechanism mobile 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 multi-degree-of-freedom controllable mechanism-type mobile ...
