Abstract
The utility model provides a chuck of a grinder, and belongs to the technical field of clamps. The chuck of the grinder solves the problems that because a hear carrier is used by an existing grinder and the contact surface between a clamping handle of the chuck and a workpiece is a smooth metal face, the workpiece can not be fixed firmly, the workpiece slides to generate deviation, and the machining accuracy is not high enough. The chuck of the grinder comprises a chuck ring of the grinder, two clamping bolts arranged in a spaced mode are connected to the chuck ring of the grinder in the radial direction through threads, a clamping handle is hinged to the chuck ring of the grinder, one end of the clamping handle stretches into the chuck ring of the grinder, the other end of the clamping handle stretches to an outer handle of the chuck ring of the grinder and is connected with a tension spring, and a concave-convex structure for increasing friction force is arranged on the arc-shaped face of the clamping handle. The chuck of the grinder has the advantages of being larger in clamping force, higher in machining accuracy of the workpiece and the like.
