Abstract

The invention provides a hook hinge structure for an electric six-freedom-degree movement platform, and belongs to the technical field of hook hinge structures used in connection parts of electric six-freedom-degree movement platforms and supporting legs. The hook hinge structure for the electric six-freedom-degree movement platform mainly comprises a hook hinge structure body particularly relating to a connection part of the electric six-freedom-degree movement platform and a supporting leg. The hook hinge structure for the electric six-freedom-degree movement platform mainly comprises the structural design of two shafts (the rotating shaft and the pin shaft) and shaft series system components of the two shafts, and the structural design of a hook hinge shell and is suitable for the application of a connection driving structure with the high speed, the heavy load and the large working space.

Description

technical field [0001] The invention relates to a Hooke hinge structure for an electric six-degree-of-freedom motion platform, in particular to a Hooke hinge structure used for the connecting part between an electric six-degree-of-freedom motion platform and an outrigger, including the structure of two shafts and their shafting components design. Background technique [0002] The six-degree-of-freedom parallel motion platform has the advantages of high rigidity, easy real-time control, high precision, small error, and large carrying capacity. It is a new product developed in recent decades and is widely used in the fields of aerospace, automobile manufacturing, ships, fields of medical diagnosis. Since the Hooke hinge has a larger rotation angle range than the spherical hinge and can withstand greater tension than the spherical hinge, the six-degree-of-freedom motion simulation platform generally uses the Hooke hinge as the passive pair. However, the Hooke hinge currently ...
