とするねじ研削盤の自動位置決め装置。 In an automatic positioning device for sequentially automatically grinding screw shafts having different shaft lengths and thread outer diameters, a first motor M1 equipped with a pulse coder rotates the screw shaft supported at the center, and a state in which the screw shaft is supported at the center. A second motor M2 equipped with a pulse coder that automatically feeds the screw shaft in the axial direction, and a third motor M3 equipped with a pulse coder that automatically feeds a grindstone for thread grinding in a direction orthogonal to the axis are provided. With,
The specifications of the screw shaft, such as the axial length, screw diameter, and screw pitch, are input, and the second and third motors are controlled to move in order to position the grindstone at the screw grinding starting position. An automatic positioning device for a screw grinding machine, characterized in that a control device is provided to control the operations of the first and second motors in order to perform appropriate screw shaft rotation and axis feed.
