Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like figure 1 , figure 2 As shown, the asymmetric space 5-DOF hybrid robot of the present invention includes a fixed frame 5 , a first length adjustment device 4 , a second length adjustment device 2 , a third length adjustment device 3 , a moving platform 6 and a positioning head 7 . The upper part of the first length adjusting device 4 is arranged in the middle of the fixed frame 5 through the first hinge 41, and its end is rigidly connected with the moving platform 6; the second length adjusting device 2 and the second The upper part of the three-length adjusting device 3 is symmetrically arranged on both sides of an end face of the fixed frame 5 through the second hinge 21 and the third hinge 31 respectively, and their ends are connected to the described fixed frame 5 through the hinges 22 and 32 with three rotational degrees of freedom r...

Abstract

A robot with five-freedom mix couple structure is disclosed, which comprises a fixed frame, a first setting adjustable in length, a second setting adjustable in length, a third setting adjustable in length, a positioning head, a movable table. Thereinto, a first hinge is provided in the middle of the fixed frame. The top of the first setting is mounted on the fixed frame via the first hinge and a shift pair that is formed by the first setting and the first hinge, the end of which connects the movable table. A second hinge and a third hinge are provided symmetrically on an end face of the fixed frame, the tops of them are mounted respectively and symmetrically on the end face of the fixed frame, and the ends connect apart with the movable table. The invention can be designed in modularization and used conveniently; the amount of moving components can be reduced, which can avoid the interference among moving components. The end performer can move with five-freedom and holds the performance of high speed, high precision, high rigidity and the trait of broad working space.

Description

technical field [0001] The invention relates to a robot, in particular to an asymmetric space hybrid robot. Background technique [0002] Known by patents GB2173472 (or EP0200369, US4790718), SE8502327 (or US4732525) and EP0674969 (or US6336375), the structure of an existing class of spatial hybrid robots with positioning heads includes at least three axially elongated Or a shortened adjustment device; one end of the adjustment device is fastened to the fixed frame through a hinge, so that it can rotate in various directions relative to the fixed frame, and the other end of the adjustment device is connected to the positioning head through a hinge; in this structure There is also an additional passive branch chain, and the additional passive branch chain is fixedly connected with the positioning head, and connected with the fixed frame through a hinge, so as to limit certain degrees of freedom of the positioning head. In the structure of this type of robot, there are passiv...
