Embodiment Construction

[0029] The five-degree-of-freedom hybrid robot of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0030] like figure 1 As shown, the five-degree-of-freedom hybrid robot of the present invention includes a fixed frame 1, a moving platform 4, a two-degree-of-freedom positioning head 6 connected to the end of the moving platform 4, and three first branch chains 8 with the same structure. Two branch chains 9 and the third branch chain 10, each branch chain all comprises the first hinge 2, the second hinge 5, the connecting rod 3 and the driving device arranged at one end of the connecting rod 3, the first branch chain 8 and the second branch chain 9 are symmetrically connected on both sides of the upper end of the fixed frame 1 through their own first hinge 2, and the third branch chain 10 runs through the fixed frame 1 and is located between the first branch chain 8 and the The bottom of the second branch c...

Abstract

The invention relates to a five-freedom-degree hybrid robot which comprises a fixing frame, a moveable platform, a positioning head, a first branch chain, a second branch chain and a third branch chain, wherein the positioning head is connected with the tail end of the moveable platform; the first, second and third branch chains are same in structure; each of the branch chains comprises a first hinge, a second hinge, a connecting rod and a driving device arranged at one end of the connecting rod; the first branch chain and the second branch chain are symmetrically connected with the two sides of the upper end of the fixing frame through own first hinges; the third branch chain passes through the fixing frame, is located under the first branch chain and the second branch chain and is connected with the middle part inside the fixing frame through the own first hinge; one ends of the first, second and third branch chains away from the driving device are respectively connected with the moveable platform through the corresponding second hinges; moveable planes of the first branch chain and the second branch chain are located in a same plane or are two mutually parallel planes; and the moveable planes of the first branch chain and the second branch chain are vertical to the moveable plane of the third branch chain. The five-freedom-degree hybrid robot is conveniently controlled in real time, the rigidity of the mechanism is effectively increased and the size of a cantilever is reduced.

Description

technical field [0001] The present invention relates to a robot. In particular, it relates to a multi-coordinate hybrid five-degree-of-freedom hybrid robot. Background technique [0002] The existing patent SE0402824 (or WO2006054935) discloses a multi-coordinate hybrid robot with a positioning head, including a fixed frame, a moving platform, a positioning head, and three vertically elongated or shortened parts connecting the fixed frame and the moving platform. Length adjustment device. Wherein, the two length adjusting devices have the same structure and are symmetrically arranged in space relative to the third length adjusting device. One end of each length adjusting device is fastened to the fixed frame through a hinge, and the other end is connected to the moving platform through a hinge with only one rotational degree of freedom. Its shortcoming is that since the two length adjustment devices with the same structure are connected with the fixed frame by hinges with...
