Abstract
The invention discloses an oscillating joint using a built-in volute spiral spring for realizing gravity balancing. The oscillating joint comprises an embedded shaft, an embedded sleeve, a volute spiral spring, two identical bearings, an inner space ring, an outer space ring, an inner nut, an outer nut, a grating support, a grating, and a reading head. Relative rotation between the embedded shaft and the embedded sleeve is realized by a bearing. When the embedded shaft and the embedded sleeve rotates relatively, grooves formed at corresponding positions of the embedded shaft and the embedded sleeve drive the volute spiral spring to generate elastic deformation, so that the volute spiral spring applies a reverse action force on the embedded shaft assembly and thus the resistance increases when the embedded shaft and the embedded sleeve rotates relatively, thereby realizing gravity balancing of the joint type coordinate measurement machine. Moreover, when the oscillating joint is in use, no friction exists and no noise is caused.
