Abstract
A clamping chuck with a chuck body, a conical receptacle for a collet chuck provided therein, a tension sleeve extending over the collet chuck, and a clamping nut disposed on the chuck body, which can be screwed together with the tension sleeve, wherein a bore, with which openings (12a,) in the clamping nut are aligned, radially extends through the chuck body, and wherein clamping pieces are radially displaceable in the bore.
Claims23
A clamping chuck, comprising:
- a chuck body having a substantially radially extending bore;
- a receptacle mounted to said chuck body and having a conically shaped portion;
- a collet chuck received within said conically shaped portion;
- a clamping nut disposed on said chuck body, said clamping nut having screw threads and a pair of openings aligned with said bore;
- a tension sleeve extending over said collet chuck, said tension sleeve having screw threads which engage with the screw threads of said clamping nut;
- clamping pieces disposed in said bore for displacement toward each other and away from each other;
- and
- an ejector mounted in said chuck body for engagement with said collet chuck and said clamping pieces,
- wherein when said clamping pieces are displaced in one direction relative to each other said tension sleeve and clamping nut are clamped together, and when said clamping pieces are displaced in the opposite direction relative to each other said ejector is axially displaced against said collet chuck to move said collet chuck in a direction away from said bore.

A balanced clamping chuck, comprising:
- a chuck body having a substantially radially extending bore;
- a receptacle mounted to said chuck body and having a conically shaped portion;
- a collet chuck received within said conically shaped portion;
- a clamping nut disposed on said chuck body, said clamping nut having screw threads and a pair of openings aligned with said bore;
- a tension sleeve extending over said collet chuck, said tension sleeve having screw threads which engage with the screw threads of said clamping nut;
- clamping pieces disposed in said bore for displacement toward each other and away from each other;
- and
- an ejector mounted in said chuck body for engagement with said collet chuck and said clamping pieces,
- wherein when said clamping pieces are displaced in one direction relative to each other said tension sleeve and clamping nut are clamped together, and when said clamping pieces are displaced in the opposite direction relative to each other said ejector is axially displaced against said collet chuck to move said collet chuck in a direction away from said bore.
