no. 1 approach

[0048] In the first embodiment, the intermediate bridging piece adapts to the adjustment of the overall posture of the guide mechanism in a manner of overall elongation or shortening.

[0049] refer to figure 1A guide rod 6031 is provided at the end of the first assembly 603 of the transfer bridge away from the third hinge axis, and a guide block 6041 is provided at the end of the second assembly 604 of the transfer bridge away from the fourth hinge axis. The guide block 6041 is provided with a through groove that cooperates with the guide rod 6031 and allows the guide rod 6031 to pass through, and the guide rod 6031 is relatively slidably connected to the guide block 6041 through the through groove. Therefore, during the reciprocating movement of any one or more of the first movable assembly 400, the second movable assembly 500, the first movable block 402 and the second movable block 502 relative to their respective matching guide rails, when the third hinge shaft and When ...

no. 2 approach

[0052] The same or similar reference numerals are assigned to the same or similar components as those of the first embodiment, and detailed descriptions of these components are omitted.

[0053] In the second embodiment, the intermediate bridge adapts to the adjustment of the overall posture of the guide mechanism in a manner of changing posture (the included angle between the first transfer bridge assembly 613 and the transfer bridge second assembly 614 changes).

[0054] refer to figure 2 , the end of the first transfer bridge component 613 away from the third hinge axis is hinged to the end of the transfer bridge second component 614 away from the fourth hinge axis, and the hinge axis is the fifth hinge axis. Therefore, during the reciprocating movement of any one or more of the first movable assembly 400, the second movable assembly 500, the first movable block 402 and the second movable block 502 relative to their respective matching guide rails, when the third hinge sha...

Abstract

The invention provides a multi-freedom-degree guide mechanism. The mechanism comprises a base table, a first guide rail, a second guide rail, a first moving assembly, a second moving assembly and a bridge assembly; the first guide rail and the second guide rail are arranged on the base table, the first moving assembly can do reciprocated motion along the first guide rail, the second moving assembly can do reciprocated motion along the second guide rail, one end of the bridge assembly is hinged to the first moving assembly, the other end of the bridge assembly is hinged to the second moving assembly, in the process that the first moving assembly does reciprocating motion along the first guide rail and / or the second moving assembly does reciprocating motion along the second guide rail, the length and / or the posture of the bridge assembly can be correspondingly adjusted, the non-completely-symmetric structure design is adopted in the guide mechanism, and the guide mechanism is suitable for coordinative work of multiple mechanisms in the limited space.

Description

technical field [0001] The invention relates to the field of robots, in particular to the composition mechanism of a parallel robot. Background technique [0002] From the mechanical point of view, robots can be divided into two categories: serial robots and parallel robots. Compared with serial robots, parallel robots have the advantages of high rigidity, strong carrying capacity, high precision and small inertia of end parts. However, most of the existing parallel robots adopt a completely symmetrical design, resulting in a large overall volume of the robot, which is not suitable for simultaneous arrangement of multiple robots in a limited space. Contents of the invention [0003] The present invention is made in view of the above-mentioned state of the prior art. The multi-degree-of-freedom guiding mechanism provided by the present invention belongs to a parallel mechanism, adopts a non-completely symmetrical structural design, and is suitable for the cooperative work o...
