Abstract

The invention discloses a parallel mechanism with two motion modes (2R1T and 2T1R). The parallel mechanism with the two motion modes (2R1T and 2T1R) comprises a rectangular movable platform and a fixed platform. The movable platform is connected with the fixed platform through a first branch chain, a second branch chain and a third branch chain, so that the transformation from the motion mode withtwo rotating and one moving to the motion mode with two moving and one rotating is realized, and the transformation of the motion modes can be realized without the need for re-assembling. The parallel mechanism with the two motion modes (2R1T and 2T1R) further has the characteristics of high rigidity, high accuracy and high flexibility.

Description

technical field [0001] The invention belongs to the field of robots and relates to a parallel mechanism with two motion modes of 2R1T and 2T1R. Background technique [0002] The parallel robot mechanism is a closed-chain form with multiple degrees of freedom and multiple loops in space. Since the 1980s, parallel mechanisms have been widely used in virtual axis machine tools, micro-motion consoles, motion simulators and multi-dimensional force sensors because of their high rigidity, large bearing capacity, small cumulative error, good dynamic characteristics, and compact structure. Widely used in other industries. Parallel mechanisms have 2, 3, 4, 5 or 6 degrees of freedom. At present, the research on parallel mechanisms with 6 degrees of freedom is relatively comprehensive and in-depth, but the reduction of degrees of freedom in parallel mechanisms will make the mechanism structure simpler, manufacturing and control The cost is relatively low, so in the case of meeting the...
