Claims

[Scope of utility model registration request]

a spline shaft that is rotatably supported in a reversible manner; an arm pivot shaft that meshes with the spline shaft and is slidable in the axial direction;
An automatic tool such as a machining center having an exchange arm fixed to the shaft end of the arm rotation shaft in a direction perpendicular to the axial direction and having a tool gripping groove at the tip, and a drive device for rotating and axially moving the arm rotation shaft. In the changing device, the changing arm is slidable in the axial direction of the arm rotation axis and in the angular force direction, and the inner end is attached to the arm rotation axis and the outer end faces the tool grip groove, and the outer end is always attached in the direction of the tool grip groove. a roller shaft that is biased to prevent the gripping tool from falling off; and a roller shaft that is slidable in the axial direction of the arm rotation shaft at the exchange arm mounting base of the arm rotation shaft and that contacts the inner end of the roller shaft to push out the roller shaft. a movable shaft operated by fluid pressure having a cam surface that locks the roller shaft in the locked state; A tool gripping mechanism for an automatic tool changer, characterized by a bowl including a spring member that constantly biases a movable shaft.
