摘要： PROBLEM TO BE SOLVED: To provide a tailstock for a cylinder grinding machine, capable of simply changing over its function between a fixed center and a rotation center. SOLUTION: The tailstock for a cylinder grinding machine, grinding the outer circumferential surface of an axial work such as a cam shaft W, is provided with a center 41 supported to a ram 23 provided for a body housing 22 by way of ball bearings 43 through 46 so as to be freely rotated. A lock pin 61 connected with a piston 62 is disposed behind the center 41 so as not to be rotated but to be freely advanced/retreated, and is formed into a projected part 472 capable of being engaged with the rear end of a mutually opposite center axial part 47 and the front end of the lock pin 61, and into a recessed part 612. When hydraulic pressure is applied to an oil chamber 63 in front of the piston 62, the lock pin 61 is moved backward so as to enable the center 41 to be freely rotated. When hydraulic pressure is applied to an oil chamber 64 in the rear of the piston, the lock pin 61 is moved forward so as to be engaged with the center 41, so that the center 41 is fixed so as not to be rotated.

摘要： PROBLEM TO BE SOLVED: To easily seal parts, and improve reliability in a gear finishing work device by constituting a work support mechanism to support a gear raw material by housing a work rotating shaft, a clutch and a work indexing motor on the same straight line in a slidingly movable cylinder. SOLUTION: A gear finishing device to perform honing by co-rotating this raw material while raising and lowering it by meshing the gear raw material with a rotating internal teeth gear-shaped grinding wheel, has a work support mechanism 40 raised and lowered by a raising-lowering means. This work support mechanism 40 is constituted in such a way that a work indexing motor 43, a coupling 44, a clutch 46 and an indexing driving shaft 47 are arranged on the same straight line in a slidingly movable cylinder 42 and a work chuck means 52 is arranged above the slidingly movable cylinder 42. The work chuck means 52 has a chuck part 61 connected through a ball 59 to a piston 58a of a cylinder 58 for a work clamp, and chucks a work W by expanding the chuck part 61 by actuation of the cylinder 58.

摘要： PURPOSE: To improve a follow-up property of a grinding wheel spindle head mounting slide table to NC control for working a workpiece with high accuracy in an NC-control system grinder. CONSTITUTION: A grinding wheel spindle head 15 is mounted to the front end of slide table 12 moved forward and backward through a ball screw mechanism 11 by a drive source such that a grinding wheel spindle head 15 in the axial center position coincides with the axis of the ball screw mechanism 11 as viewed in a plan. A grinding reaction will be received by the ball screw mechanism 11 without exerting inclining moment laterally to the slide table 12 to improve the follow-up property of the slide table 12 to NC control. Also, the grinding wheel spindle head 15 is mounted to the slide table 12 with the posture inclined forward downward. Thus, the height of the grinding wheel 18 is reduced, the vertical distance between the action line of the grinding reaction and the axis of the ball screw mechanism 11 is shortened and the vertically inclining moment acting on the slide table 12 is reduced.
