ホイール加工用フインガチヤツク。[Claims for Utility Model Registration] (1) A connecting pin 24 is attached to the tip of an arm 19 in the radial direction of a yoke 18 that is connected to a drawbar 17 that is movable in the axial direction of the main shaft and moves back and forth within the chuck body 11. A lever 31 is mounted to be able to swing in the radial direction through the lever 31, and between this lever and the chuck body 11, the lever 31 is guided in parallel on the retracting end side of the draw bar 17, and the draw bar 17 is guided in parallel on the protruding side of the draw bar 17. A guide pair 30 is provided, which includes a dogleg-shaped guide groove 32 that guides the lever 31 to swing outward in the radial direction as the lever 31 advances, and a guide pin 33 loosely fitted therein. This finger chuck for wheel machining is characterized in that a finger claw 36 for clamping the outer peripheral edge of a workpiece is fixed to the tip of the lever 31 and a clamp seat 38 fixed to the end face of the chuck body 11. (2) A center jig 42 is provided at the center of the end face of the chuck body 11 and is swingable in the axial direction of the chuck and is biased in the advancing direction by a spring 44, and aligns the center axis of the workpiece 51 with the center axis of the chuck body 11. The center guide 45 for positioning is attached to this center jig 42.
2. A finger chuck for wheel machining according to claim 1, wherein the finger chuck is fixed to a wheel.
