Abstract

The invention relates to the indexing of the workbench of a machine tool. The technical proposal is: comprising a rotary indexing workbench, a movable toothed plate, a fixed toothed plate, a fastening toothed plate and a base. The center of the base is fixed with a concave conical upper end. The lower support seat of the hole, the concave conical hole is equipped with a rotary ball, the upper part of the rotary ball is exposed from the concave conical hole, and the upper part of the rotary ball is contained in the concave shape at the center of the lower side of the rotary indexing table. In the conical hole, the movable toothed plate is divided into 12 equal parts along the direction of the fan-shaped surface, and the fixed toothed plate is processed with three 30° conical tooth surfaces. The angle between the centerlines of two adjacent tooth surfaces is 120°, the fixed tooth disc between two adjacent tooth surfaces is a smooth surface.

Description

Technical field [0001] The invention relates to the field of indexing devices for machine tools, in particular to an indexing device for a workbench of a numerically controlled machine tool. Background technique [0002] At present, CN 2158765Y discloses a kind of internal and external conical tooth indexing plate, its structural feature is that the bevel gear with external teeth and the matching internal bevel gear have a split line tooth shape (or other conjugate tooth shape) , The tooth shape shrinks along the tooth direction, and the bottom of each tooth is undercut. When the external gear enters the internal gear and axially fits, each tooth can get a tight fit without backlash. CN 87203027U discloses a rotary positioning device, the structure of which is that there are a plurality of conical holes on the combined surface of the rotary table and the base, and these holes are evenly distributed on a circle centered on the center of the rotary center, on the base There a...
