Abstract
A kind of pearl drill chuck, including chuck body, the chuck body is axially provided with through hole, ceramic tube is provided in through hole, the chuck body two a group of clamping pearls, chuck body and pearl clamping surface are concave arc surface, arc surface is radially provided with powder groove.The utility model discloses by being additionally provided with ceramic tube in the through hole of chuck body, the setting of ceramic tube significantly improves the wear resistance of chuck, solves the problem that the aperture is expanded or deformed in the wear of traditional chuck due to the insufficient wear resistance of traditional chuck.Meanwhile, the lower thermal conductivity of ceramic tube can effectively block the transmission of heat to chuck body, avoids the deformation of chuck body due to heating, improves the service life of chuck.
