Claims

[Scope of utility model registration request]

In a thread groove alignment device for a thread grinding machine that sequentially thread-grinds threaded workpieces of the same shape, a main shaft equipped with a clamping tool for positioning and holding the threaded workpiece in a predetermined position is rotated around its axis (C-axis). A motor for driving a main spindle, a table feeding motor for reciprocating a table on which a headstock for pivotally supporting the main spindle is mounted along the axial direction (Z-axis) of the main spindle, and a grindstone for moving a grindstone to the screw of the threaded workpiece. A grindstone motor for reciprocating in the direction of cutting into or away from the groove (X-axis), a grindstone drive motor for rotationally driving the grindstone, and an NC device connected to each of the motors to control their operation. , the various specifications necessary for thread grinding, such as the thread lead, the approach dimensions of the threaded workpiece, the grinding stroke, the spindle rotation speed and related table feed speed, the grinding wheel rotation speed, the cutting depth of the grinding wheel, and the grinding wheel inclination angle. It memorizes and issues an input command to the NC device, and also reads the stop position of the main spindle around the C-axis (referred to as a C-axis value) when machining of the first threaded workpiece is completed, stores the value, and issues an input command to the NC device. specifications input means, and the NC device starts a table stroke when the second screw workpiece positioned and fixed on the spindle rotates to the position of the C-axis value, and also performs a table stroke based on the input specifications. A thread groove positioning device in a thread grinding machine, characterized in that the thread groove positioning device is configured to control a thread grinding operation by using a thread grinding machine.
