Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0035] like figure 1 As shown, it is a schematic structural diagram of the non-coplanar hinge of the rotating shaft in the specific embodiment of the present invention. The non-coplanar hinge of the rotating shaft includes an upper link 1, an upper bracket 2, an offset cross shaft 3, a lower bracket 4 and a lower link 5; The upper bracket 2 and the lower bracket 4 have the same structure and size, and can be interchanged, and the bracket name is not used to limit their actual lower positional relationship; when using the rotating shaft non-coplanar hinge of the specific embodiment...

Abstract

The invention relates to the technical field of hinge design, and particularly provides a calculation method for a working space of a rotating shaft non-coplanar hinge, and the calculation method comprises the steps: S1, determining geometric parameters of the rotating shaft non-coplanar hinge; s2, determining three characteristic angles of the rotating shaft non-coplanar hinge according to the geometric parameters; determining an interference motion range of the rotating shaft non-coplanar hinge according to the three characteristic angles; s3, determining an interference motion equation of the rotating shaft non-coplanar hinge according to the interference motion range; and S4, calculating the working space of the rotating shaft non-coplanar hinge according to the interference motion equation. According to the calculation method, the calculation precision is high, the design of the rotating shaft non-coplanar hinge is easy to realize, and meanwhile, rapid calculation is also easy to realize.

Description

technical field [0001] The invention relates to the technical field of hinge design, in particular to a method for calculating the working space of a rotating shaft non-coplanar hinge. Background technique [0002] The general parallel robot design is a long-term optimization process. In each round of design, multiple models need to be established and repeated iterative upgrades. For the non-coplanar hinges of the rotating shafts used by the parallel robots, more Subsequent modeling and continuous improvement. The design process takes a long time, which has a certain impact on the development progress of the project. Therefore, how to shorten the design process of the non-coplanar hinge of the rotating shaft has become an urgent problem for designers in this field. [0003] In the design of the non-coplanar hinge of the rotating shaft, the designer generally only roughly calculates and analyzes the working space of the hinge according to the maximum rotation angle of the hi...
