Dissociation possible tool fixed feature and this being tool null tool fastening

摘要

Apparatus has a casing 2 clamping tool, in the casing, for receiving the 4 end portion clamping the tool shaft, which tapers in the tool part 5, an opening 3 tightening, is constructed. Opening 3 side further, and is tapered towards the inside, and and are tapered in the direction of introduction portion 4 end clamping of the tool part 5 is a plane that extends perpendicular to the introduction of the tightening direction at and are inclined to one another, thereby opening has a trapezoidal cross-section, at that time, and decreases in the direction away from the opening of the opening 3 the length of the cross-section clamping. The casing 2 has a side opening 7 Further, in the lateral opening, the lateral opening is receiving the locking pin and intersects the opening tightening. Edge 20 when it is introduced into the apparatus clamping the tool is tapered pin 8 engages with the front edge 21 of the elongated hole 9 that is configured within four edge clamping of the tool part 5, and, while the draw in the opening 3 engaging action arising tightening deeper section 4 end tightening, pin 8 is pushed into the side opening 7 in deeper. When the tapered double aperture 3 tightening, the combination of a vertical locking to be give rise by 8 locking pin, the inside of the achievable manufacturing tolerances by a mass production method of a conventional six degrees of freedom of all the tool parts to allow, to be limited to.
