The invention discloses a parallel mechanism with five degrees of freedom. The parallel mechanism comprises a frame, a movable platform, a first branched chain, a second branched chain and a third branched chain, wherein the first branched chain is connected with the frame through at least two rotating pairs with vertical intersecting axes, and is connected with the movable platform through at least two rotating pairs with vertical intersecting axes; the second branched chain is provided with the same structure with the first branched chain; the third branched chain comprises a main sub branched chain and two secondary sub branched chains; and the first branched chain, the second branched chain and the third branched chain are respectively connected between the frame and the movable platform, and form a space parallel mechanism, enabling the movable platform to realize three degrees of rotating freedom and two degrees of moving freedom, with the frame and the movable platform. The parallel mechanism with five degrees of freedom can be expanded to a series-parallel multi-axis linkage device for realizing multi-axis linkage numerical control machining, such as machining of complicated parts and large structural parts and different-place maintenance of large equipment.
Description
technical field [0001] The present invention relates to the technical field of mechanical design and mechanical manufacturing, in particular, the present invention relates to a parallel mechanism with five degrees of freedom and a multi-axis linkage device including the parallel mechanism. Background technique [0002] In related technologies, in the field of mechanical design and manufacturing, with the development of the industrial level, the service requirements and design level of mechanical parts have been continuously improved, and its processing and manufacturing processes have become more stringent and complex, which puts forward new requirements for modern processing equipment. challenge. In order to improve the rotation flexibility, compliance, efficiency and precision of processing, the processing equipment should have at least five-axis linkage processing capability and good static and dynamic characteristics. At the same time, under harsh working conditions, it ...
