Claims

[Claims for Utility Model Registration] (1) A device for positioning a donut-shaped workpiece having a hole in the center, which has a plurality of workpiece placement parts on the same circumference, and each workpiece placement part has a plurality of workpiece placement parts on the same circumference. a rotary table provided with a positioning hole for positioning the workpiece by matching the hole portion thereof, and a rotary table provided on the back surface of each workpiece mounting portion of the rotary table so as to be movable forward and backward relative to the center of the positioning hole, A plurality of work engaging means each having an engaging claw that engages with the inner circumferential edge of the hole of the workpiece placed on each of the workpiece placement sections by a backward movement, and disengages from the inner circumferential edge of the hole of the workpiece by a forward movement. and a first urging means for urging each of the workpiece engaging means to move backward;
The rotary table is provided on the back surface of each workpiece mounting section so as to be movable forward and backward with respect to the center of the positioning hole, and the workpiece engaging means is moved backwardly from the center of the positioning hole by a backward movement, while the workpiece engaging means is moved backwardly by a forward movement. a cam member having a cam surface that causes the cam member to move forward to the center of the positioning hole; a second urging means that urges the cam member to move backward; a cam member that resists the urging force of the second urging means; A workpiece positioning device comprising a moving means for moving the workpiece forward. (2) The moving means is provided on the fixed side so as to move forward the cam member on the side of the workpiece placement section which is rotated to the workpiece loading position and the workpiece unloading position. Work positioning device.
