WIPO Patent Application WO/2020/237580
Kind Code:

Abstract:
Disclosed are a rotary joint electromagnetic locking device and a rotary joint. The rotary joint electromagnetic locking device comprises a first electromagnetic chuck, a sliding disk, a rotary disk, a connecting shaft for connecting the first electromagnetic chuck and the sliding disk, and a second electromagnetic chuck; when both the first electromagnetic chuck and the second electromagnetic chuck have no attractive force, the sliding disk and the rotary disk are mutually lockable; when the second electromagnetic chuck has an attractive force, the rotary disk or the first electromagnetic chuck is attracted by the second electromagnetic chuck, so that the sliding disk is further locked to the rotary disk; and when the first electromagnetic chuck has an attractive force, the sliding disk can be attracted to a first contact face of the first electromagnetic chuck, so as to release the sliding disk from the rotary disk. In this way, the present invention enables tight locking of two rotary parts.
