Claims

[Scope of utility model registration request]

A tool mounting hole is formed in the tip of the spindle mounted on the headstock, and a gripping member having a diameter smaller than the minimum diameter of the mounting hole grips the gripping portion of the tool mounted in the tool mounting hole. , a support sleeve that supports the gripping member so that it can be pulled out toward the tip side of the main spindle is disposed inside the tip of the main spindle; A draw rod connected to the main shaft and only allowed to move in the axial direction is disposed through the draw rod in the axial direction, and coolant is supplied to the axial center of the draw rod to the tool mounted in the mounting hole. A flow path is bored in the axial direction, and a nut member having at least one end protruding from the rear end surface of the main shaft is screwed to the rear end of the draw rod, and a nut member is screwed into the rear end of the draw rod, and a nut member is screwed into the rear end of the draw rod. A spring for pushing the draw rod backward is provided, and an engagement portion into which a rotation preventing member can be inserted is formed on the outer peripheral surface of the end of the nut member that protrudes from the rear end surface of the main shaft. At a location where rotation of the spindle axis is restrained with respect to the base, a locking member is provided that engages with the outer circumferential surface of a detent member inserted into the retaining portion of the nut member to restrain rotation of the nut member. A spindle device having a coolant supply function characterized by forming a surface.
