Claims

[Scope of utility model registration request]

A fitting hole 15 is provided at the tip of the gripping member 12, which is rotatably driven by a drive source 2 such as an air motor and rotatably supported by the main body 1, into which a mounting portion of a processing member such as a cutting tool is fitted. , a tapered portion 16 extending in the axial direction is provided on the outer circumference thereof, a cylindrical tightening member 17 is provided around the gripping member 12, and the tapered portion is provided on the inner circumference of the tightening member 17. 16 and a tapered portion 18 that can be tapered fitted,
On the other hand, the gripping member 12 and the tightening member 17 are configured to be movable relative to each other in the axial direction, and the tapered portions 16 and 18 are fitted together by relative movement of both members 12 and 17 by the relative movement means 37. Sometimes, the attachment for automatic machines such as robots is configured to grip the workpiece at the inner circumference of the insertion hole 15 and release the workpiece by releasing the fitting, and the relative movement is The means 37 includes a biasing means 29 for biasing the members 12 and 17 to move relative to each other in either the fitting direction or the unfitting direction between the tapered portions 16 and 18; It is arranged in a piston chamber 30 provided in the piston chamber 30 and is driven by a fluid supplied to and discharged from the piston chamber 30 to move the members 12 and 17 in a direction opposite to the above direction against the biasing force of the biasing means 29. An attachment for automatic machines such as robots, characterized by comprising a piston 31 that is moved relative to the piston 31.
