Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Embodiments of the present invention provide a parallel robot, such as figure 1 As shown, it consists of a moving platform 1, a fixed platform 9, and three branch chains connecting the moving platform 1 and the fixed platform 9. The first branch chain and the second branch chain in the three branch chains have the same structure, and the two branch chains have the same structure. The branch chain is composed of a universal joint pair, a cylindrical pair and the connecting rod between them from top to bottom. The third branch chain in the three branch chains is composed of a spherical joint pair, a rotary joint, and a Cylindrical pairs and connecting rods between them;

[0018] One end of the connecting rod L1 of the first branch chain is connected to the m...

Abstract

The invention relates to a parallel robot. The parallel robot consists of a motion platform, a fixed platform and three branched chains connected with the two platforms; the first branched chain and the second branched chain in the three branched chains have the same structures; the two branched chains respectively consist of universal joint pairs, cylinder pairs and connecting rods therebetween from top to bottom; and the third branched chain in the third branched chains consists of a spherical hinge pair, a rotating pair, a cylinder pair and a connecting rod therebetween from top to bottom. The parallel robot is simple in mechanism, easy to manufacture and simple in kinetic model, enables the kinetic calibration and control to become easy, is few in mechanism joints, and improves the structural rigidity.

Description

technical field [0001] The invention relates to the field of robots, in particular to a parallel robot. Background technique [0002] The parallel robot mechanism is connected by more than two branch chains between the fixed platform and the motion platform. Each branch chain is composed of a connecting rod and a motion pair. The motion platform has more than two degrees of freedom and is driven in parallel. , which is very different from the transmission series robot in terms of mechanism, kinematics, and dynamics. [0003] Parallel robot mechanisms are widely used in technical fields such as CNC machine tools, micro-operation, boiler maintenance, product manufacturing and processing, and researchers have also invented many parallel mechanisms. However, there are still some deficiencies in the existing parallel robot mechanism, such as poor manufacturability, complex structure, and high manufacturing cost. Contents of the invention [0004] The object of the present inv...
