Problems solved by technology

[0003] The limitation of the above mechanism is that the parallel frame has extremely high requirements on the processing accuracy of the connecting rod, which makes the processing cost very high and is not conducive to improving the positioning accuracy of the mechanism

Abstract

The invention discloses a parallel mechanism with a two-degree-of-free translation function. The parallel mechanism comprises a fixed frame, a movable platform, two driving branched chains identical in structure and a driven branched chain, the two driving branched chains are symmetrically arranged between the fixed frame and the movable platform and on two sides of the driven branched chain, the driven branched chain comprises two rod members in left-right parallelism, the upper ends of the rod members are connected with the fixed frame through a rotating pair while the lower ends of the same are connected with the end portion of a horizontal connecting rod, the fixed frame, the two rod members and the horizontal connecting rod form a parallelogram structure, a vertical connecting rod perpendicular to the horizontal connecting rod is fixedly connected below the middle portion of the horizontal connecting rod, and the movable platform comprises a transverse rod and a vertical rod which is vertically fixed above the middle portion of the transverse rod and connected with the vertical connecting rod through a moving pair. The parallel mechanism is low in manufacturing cost, smoother in operating and higher in motion transmitting efficiency.

Description

Technical field [0001] The invention belongs to a parallel manipulator, and specifically relates to a parallel mechanism with two degrees of freedom translation. Background technique [0002] Parallel robots have the advantages of no cumulative error, high accuracy, compact structure, high rigidity, and large carrying capacity. They have been widely used in all aspects of life such as military industry, biomedicine, and sports simulation. At present, as an important part of a parallel robot, a parallel mechanism that can realize two-degree-of-freedom translation includes two active branch chains and a moving platform, and each branch chain includes two parts, an active arm and a driven arm. One end of the active arm has only one degree of rotational freedom relative to the fixed frame, and the other end is connected to one end of the driven arm through a rotating pair; the other end of the driven arm is connected to the moving platform through a rotating pair to ensure translatio...
