Abstract

The invention relates to a rotating controllable connecting rod mechanism. An upright post is connected with one end of a main arm and the first connecting end of a first rocker arm; the second connecting 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 connecting end of a second rocker arm; the first connecting end of the second rocker arm is connected with the other end of the main arm; the third connecting 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 connecting end of the first rocker arm; one end of a third connecting rod is connected with the fourth connecting end of the second rocker arm; the other end of the third connecting rod is connected with a fourth connecting rod; one end of a connecting block is connected with the upright post through a fixed pair, and the other end of the connecting block is connected with a fifth connecting rod; the fifth connecting rod, a sixth connecting rod, a seventh connecting rod and the third connecting end of the main arm are connected in sequence. The rotating controllable connecting rod mechanism has the advantages of large work space, high rigidity, high bearing capacity and high implementation accuracy.

Description

technical field [0001] The invention relates to the field of robots, in particular to a rotary controllable link mechanism. Background technique [0002] Compared with the traditional serial robot, the parallel robot has no cumulative error, high precision, compact structure, large bearing capacity, high rigidity and small inertia of the actuator. 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 rotary controllable link mechanism, which can solve the shortcomings of traditional tandem rob...
