Abstract
PURPOSE: To maintain stable strong holding capability even if a held object has different diameters in the axial direction, by moving holding members to hole all the portions of the different diameters.
CONSTITUTION: An operating sleeve 2, which has a tapered inside surface 2a and can be moved back and forth in the axial direction of the body 1 of a product holding appliance 1 of a chuck mounted on the main shaft of a machine tool or a loader, is provided in the body 1. Holding members 3 are supported with springs in the internal opening of the sleeve 2. Balls 5 are provided in contact with the surface 2a and the tapered outside surfaces of the holding members 3. Whenever the diameter of a held workpiece changes, the tangents on the balls 5 and the surfaces 3a are displaced and the balls 5 are moved on the surfaces 3a by the relative axial movement of the sleeve 2 to push the holding members 3 inwards in the radial direction of the sleeve 2.
