Embodiment Construction

[0018] 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.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0020] Such as figure 1 As shown, a multi-support double platform mechanism is composed of a moving platform 1, a fixed platform 12 and three branch chains connecting the above two platforms. The first branch chain and the second branch chain in the three branch chains have the same structure. The two branch chains are composed of a ball pair, a rotating pair, a moving pair and the connecting rod between them from top to bottom. The third branch chain in...

Abstract

The invention discloses a multiple support and double platform mechanism. The multiple support and double platform mechanism is composed of a moving platform, a fixing platform and three branched chains connected with the moving platform and the fixing platform, wherein the first branched chain and the second branched chain of the three branched chains are of the same structure, each of the first branched chain and the second branched chain is composed of a ball pair, a rotation pair, a moving pair and connection rods among the ball pair, the rotation pair and the moving pair, which are arranged from top to bottom, and the third branched chain in the three branched chains is composed of another ball pair, another two rotation pairs, a cylindrical pair and connection rods among the another ball pair, the another two rotation pairs and the cylindrical pair. The multiple support and double platform mechanism is of a parallel robot structure, and the moving platform in the parallel robot structure of the multiple support and double platform mechanism can achieve three types of movement output, and therefore the multiple support and double platform mechanism is simple in structure, easy to process and manufacture, and simple in kinematic model, facilitates kinematic calibration and control, and simultaneously comprises a small quantity of mechanism joints, and improves structural rigidity.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a multi-support double-platform mechanism. 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 robots, CNC machine tools, sensors, micro-operations, 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...
