ENERGIZING MECHANISM OF CLAMP DEVICE
Document Type and Number:
Japanese Patent JP2017127941
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an energizing mechanism of a clamp device which can regulate rotation of a turntable by a sufficient pressing force.SOLUTION: An energizing mechanism 30 of a clamp device 28 is configured from: a movable member 32 which is movable in an axial direction of a revolving shaft 14, and has a first guide face 44 which receives a ball 50; a reception member 60 which is provided on a stationery frame 12 side, and has a second guide face 62 which receives the ball 50 together with the guide face 44; and a pressing member 70 which is movable in the axial direction, has a third guide face 72 which receives the ball 50 guided by the guide faces 44, 62, and is pressed in a movement direction of the movable member 32 via the ball 50. All guide faces 44, 62, 72 are so made as to have a R-groove shape with which the ball 50 is brought into line contact, whereby the pressing member 70 can be pressed by a sufficient surface pressure without provision of the ball 50 on the whole circumference of the revolving shaft 14 so as to hold a clamp disc 90 and reliably regulate rotation thereof.SELECTED DRAWING: Figure 1
