Abstract

The invention relates to a stable collet chuck structure and a machine tool applying the same, and belongs to the field of machine tool clamps. The stable collet chuck structure comprises a taper shank, a connecting piece, a connecting rod, a chuck and a locking piece, wherein the connecting piece is rotationally connected to the end part of the taper shank in a sleeving mode and is used for being connected with a power head, the connecting rod is connected to one end, close to the connecting piece, of the taper shank, moreover, a mounting groove is formed in the connecting rod, the chuck is arranged in the mounting groove in a penetrating mode, and the locking piece is connected to the connecting rod and is used for tightening the chuck. The stable collet chuck structure has the effects that the overhanging length of a cutter can be reduced, the vibration of the cutter during machining is reduced, and then the machining precision is improved.

Description

technical field [0001] The present application relates to the field of machine tool clamps, in particular to a stable collet structure and a machine tool using the structure. Background technique [0002] A collet is a locking device for holding a tool or workpiece, usually used on drilling and milling machines and machining centers. The bed of the machine tool is usually equipped with a spindle for clamping the workpiece and a tool holder for installing the tool. The tool holder is provided with a power head, and the collet is usually installed on the power head of the machine tool. The workpiece moves, and at the same time, the power head drives the tool to rotate to realize the processing of the workpiece. [0003] In view of the related technologies mentioned above, the inventor believes that when the collet is far away from the spindle, the overhang length of the tool is longer, so the tool is prone to vibration during machining, resulting in reduced machining accuracy...
