Abstract

The invention provides an indexing and positioning mechanism for a turret tool holder, which includes a main shaft and a box body, and the box body is arranged around the main shaft. Set on the front end of the main shaft, the cutter head is installed on the movable toothed plate, the positioning plate is set on the box body, the locking toothed plate is set on the main shaft body and can move along the axial direction of the main shaft on the main shaft body, and the locking toothed plate passes through The conical teeth arranged at the front end mesh with the movable toothed plate, and the locking toothed plate is connected with the positioning plate through the guide positioning pin. The invention has reasonable structure and obvious effect.

Description

technical field [0001] The invention belongs to the technical field of tool holders for numerically controlled machine tools, and in particular relates to an indexing and positioning mechanism for turret tool holders of numerically controlled machine tools. Background technique [0002] Most of the current CNC tool holders use toothed discs for indexing and positioning. There are two types of toothed discs: double toothed discs and triple toothed discs. U.S. Patent US20050247172A1 adopts a duplex toothed disc structure, which is relatively simple in structure and only consists of a movable toothed disc and a fixed toothed disc. The movable toothed plate is installed on the main shaft, and the fixed toothed plate is installed on the box body. The teeth of the two toothed plates are opposite to each other, and the moving toothed plate slides back and forth to realize meshing and separation. Since the cutter head is installed on the movable toothed plate, the mass of the movab...
