It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0021] In order to solve the problems existing in the prior art, the utility model proposes a quick-change and self-locking device for a transfer ring driving mechanism, the device comprising: a transfer ring body 10; a driving mechanism 40; a quick-change mechanism 30, which is divided into a front-end quick-change mechanism 31 and a central quick-change mechanism 32, one end of the front-end quick-change mechanism 31 is connected to the transfer ring body groove 12 and can move along the transfer ring body groove 12, and the other end is connected to the protruding end of the driving mechanism 40 connected to the transfer ring body 10, and the central quick-change mechanism 32 is arranged on the front-end quick-change mechanism 31. The quick-change mechanism 30 is connected to the cylinder body of the driving mechanism 40 and plays the role of fixing the driving mechanism 40; the self-locking mechanism 20, one end of the frame connecting piece 21 at the bottom is embedded and connected with the rib plate 13, and the other end is connected to the front quick-change mechanism 31 through the stepped shaft 26.

The cooperation between the buffer shaft 22 and the wedge-shaped piece 23 ensures the positioning accuracy. At the same time, the fixing spring 24 and the buffer spring 25 provide the functions of self-locking and quick unlocking.
