Claims

[Scope of utility model registration request]

In a workpiece positioning device of a press machine for C-chamfering, which positions the workpiece in a predetermined position when performing C-chamfering on a workpiece, a screw in which a right-handed threaded portion and a left-handed threaded portion are formed with an intermediate portion as a boundary. a first support block that is screwed onto the right-hand threaded portion of the threaded rod and moves in the direction of the center axis of the threaded rod; a first support block that is threaded onto the left-hand threaded portion of the threaded rod and moves in the direction of the center axis of the threaded rod; a second support block that moves to;
a pair of guide plates that are rotatably supported by each of the first and second support blocks and guide the workpiece; and a fan-shaped guide plate that is fixed to each of the guide plates and has teeth formed on its peripheral edge. A pair of worm wheel plates, a pair of worm gears that are in mesh with each of the teeth of the worm wheel plates and rotatably supported by the first and second support blocks, and a pair of worm gears that are in mesh with each of the worm gears. and a pair of worm wheels supported by the first and second support blocks, and a pair of worm wheels disposed substantially parallel to the threaded rod, supporting the worm wheels so as to be freely slidable in the axial direction, and rotating the worm wheels. 1. A workpiece positioning device for a press machine for C chamfering, characterized in that the workpiece positioning device is provided with a shaft member for positioning.
