Description
Technical Field
The utility model relates to the technical field of machining, in particular to a machine tool chuck for machining a circular workpiece.
Background
Generally, when a circular workpiece is machined, three-jaw and four-jaw distances of a machine tool are often insufficient to clamp the circular workpiece, so that the surface, particularly the inner surface, of the circular workpiece is not machined well.
Disclosure of Invention
In order to solve the problems, the utility model provides a chuck which is matched with a machine tool chuck to clamp circular workpieces with different sizes, so that the surface of the circular workpieces can be conveniently machined.
The specific technical scheme is as follows:
a machine tool chuck comprises a base, a positioning block, a clamping block and a sliding block, wherein the positioning block, the clamping block and the sliding block are arranged above the base, the positioning block is fixedly connected with the base, the sliding block is in straight-face sliding fit with the positioning block, the sliding block is in inclined-face sliding fit with the clamping block, the sliding block is in elastic fit with the base through bolts, and the clamping block is in sliding fit with the base.
The sliding block is matched with the positioning block in a dovetail groove, and the sliding block is matched with the clamping block in a dovetail groove.
