Document Type and Number:
WIPO Patent Application WO/2018/210014
Kind Code:
A1
Abstract:
A tool for locking and dismounting a bolt and a battery changing robot, used for locking and dismounting the bolt during a battery changing process of an electromobile. The tool comprises a socket (1) which can move and/or rotate under the driving of a power source. One end of the socket (1) is provided with a first mating hole (11) for driving the bolt (4) to be locked or dismounted to rotate, and a bottom end of the first mating hole (11) is provided with a tapered hole (12) for receiving and supporting the end of the bolt (4). During the battery changing process of the electromobile, in particular during locking of the bolt (4), the tool can provide reliable support for the bolt (4), and at the same time, can remarkably reduce the abrasion between the bolt (4) and the inner wall of the tapered hole (12), thereby prolonging the service life of the bolt (4) and the socket (1).
