リーブのロツク機構。 In a drive mechanism for a tailstock sleeve that performs forward and backward movement by a drive piston of a hydraulic cylinder, a sub-cylinder chamber is provided coaxially with the hydraulic cylinder, and the rod of the drive piston fits loosely into the sub-cylinder chamber. A flange with a tapered hole is provided, and a collet is slidably fitted onto the rod and has a slotted taper portion similar to the taper hole, and the taper portion of the collet is biased toward the taper hole. and a floating piston that pushes back the collet with hydraulic pressure against the biasing force of the elastic member, and further includes a pipe for supplying the hydraulic pressure to the sub-cylinder chamber. Features a tailstock sleeve locking mechanism.
