AUTOMATICALLY SUPPLIED PART MACHINING DEVICE UTILIZING VERTICAL MOVING MECHANISM

PURPOSE:To reduce an error in adhesion between a reference plane and a product to stabilize machining accuracy by improving adhesion between a workpiece and a jig as the jig ascends, or when the jig stops temporarily or moves upward. CONSTITUTION:A product carrying in guide is fixed onto a base attached to a main body 6 to supply a product 1. Next a jig 2 moves to a lower end to transfer the product 1 onto the V-groove of the jig 2 by a pushing out rod. A slide unit to which a compression coil spring is attached is advanced by a driving wire to abut the end face of the coil spring against the reference plane of a hard material 5 attached to the main body 6. The jig 2 ascends to bring the side of the coil spring into contact with the product for making the product 1 precisely adhere to the V-groove of the jig 2, which stops at this position. Since when the coil spring moves back as it is, the product 1 adhering to the V-groove falls down, after a pressing plate advances to fix the product 1, the coil spring moves back.
