Abstract

A controllable multi-degree of freedom welding robot comprises four controllable four-link-mechanism closed-loop executing mechanism subchains which are in parallel connection and an executing main chain in series connection. A main chain connecting rod can be controlled by the controllable four-link-mechanism closed-loop executing mechanism subchain to move within the surface with the controllable four-link-mechanism closed-loop executing mechanism subchains. The spatial motion of a moving platform can be achieved by the motion of a first connecting rod and a body. According to this arrangement, the spatial motion of an end effector can be achieved, motion inertia is small, dynamics performance is good and reliability is high. The controllable multi-degree of freedom welding robot has the advantages of being compact in structure and easy to control. The rods can be made as light rods, work spaces for mechanisms are large, gravity centers of the mechanisms are moved backwards to keep balance. The controllable multi-degree of freedom welding robot can be widely used.

Description

technical field [0001] The invention relates to the field of robots, in particular to a controllable multi-degree-of-freedom welding robot. Background technique [0002] The traditional series robot has the advantages of simple structure, low cost, and large working space. Relatively speaking, the series robot has low rigidity and cannot be applied to high-speed and large-load occasions; compared with the traditional series robot, the parallel robot has no cumulative error, High precision, compact structure, large bearing capacity, high rigidity and small inertia of the end effector, etc., 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; However, the obvious disadvantages of parallel robots are small working space and complex structure. The existing manipulators with partial closed chains in engineering, such as MOTOMAN-K10, did not solve the problem...
