Abstract

PURPOSE: To internally clamp a work without causing distortion or deformation, by adapting the projection of each pair of pins to each other which are fitted to both tapered sides of block pieces in accordance with the ruggedness of the work's internal wall.
CONSTITUTION: When a pin 17 is pressed to a portion inwardly bulged on the internal wall of work 24, a headed trigonal pyramidal block piece 9 which is fitted to the tip of a hydraulic rod 5 for pressing the pin 17 recedes with bosses as fulcrums against a leaf spring 20 to adjust the projection of the pin 17. The other pin 17 fitted to another tapered side of a block piece 9 is pushed out as a reaction of the said movement just by the amount of the recession, which adds nearly an even hydraulic pressure on the internal wall of the work 24 and chucks the work from the inside without causing distortion or deformation.
