COLLET CHUCK FOR CLAMPING SHAPED PARTS

摘要

FIELD: metal cutting, possibly devices for clamping cams with curvilinear working surfaces. SUBSTANCE: collet chuck includes body 1. Pressure member 2 and collet 16 are arranged in said body. Member 2 has cone surface on its one end. Collet 16 has carrier 23 mounted in opening of collet in such a way that it extends over end surface of said collet by value no more than thickness of worked shaped part. Opening of collet 16 is stepped one. Carrier 23 is mounted with possibility of embedding to collet at frontal engagement with part 8 at time moment of setting. In order to provide it, carrier has tapered end surface and flat on its lateral surface for engaging with lateral surface of part at working operation. EFFECT: improved design. 4 cl, 3 dwgs
