Abstract

The invention relates to a mobile connecting rod mechanism. A vertical column is connected with one end of a main arm and a first connecting end of a first rocker arm; a 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 a second connecting end of a second rocker arm; a first connecting end of the second rocker arm is connected with the other end of the main arm; a 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 a third connecting end of the first rocker arm; one end of a third connecting rod is connected with a 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 connection block is connected with the vertical column through a fixing pair; the other end of the connection block is connected with one end of a fifth connecting rod; the other end of the fifth connecting rod is connected with one end of a sixth connecting rod; the other end of the sixth connecting rod is connected with the middle part of the main arm. The mobile connecting rod mechanism has the advantages of large working space, high rigidity, strong bearing capacity and high executing precision.

Description

technical field [0001] The invention relates to the field of robots, in particular to a movable 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 movable link mechanism, which solves the shortcomings of traditional tandem robots about large torque requ...
