Abstract

The invention provides an indexing and positioning mechanism of a rotary-tower knifetool rest, comprising a main shaft and a box body, wherein the box body is arranged at the periphery of the main shaft. The indexing and positioning mechanism is characterized by also comprising a locking tooth disc, a positioning disc and a movable tooth disc, wherein the movable tooth disc is arranged at the front end of the main shaft; the movable tooth disc is provided with a knifetool disc; the positioning disc is arranged on the box body; the locking tooth disc is arranged on a shaft body of the main shaft and can move on the shaft body of the main shaft along the axial direction of the main shaft; the locking tooth disc is meshed with the movable tooth disc by conical teeth arranged at the front end; and the locking tooth disc is connected with the positioning disc by a guiding and positioning pin. The indexing and positioning mechanism provided by the invention ahs the advantages of 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 mov...
