Abstract

The invention relates to a quick indexing head, which comprises a box body, a main shaft, a gear, a driving rack, a driven rack and a transition gear, wherein the main shaft, the gear, the driving rack, the driven rack and the transition gear are positioned in the box body; the gear is fixedly connected with the main shaft; the driving rack is meshed with one side of the gear; the driven rack is meshed with the other side of the gear; the transition gear is positioned at the bottom of the gear; the driving rack is meshed with one side of the transition gear; the driven rack is meshed with the other side of the transition gear. According to the quick indexing head, the influence of inter-tooth gaps between the gear and the racks on indexing is eliminated, and the indexing accuracy is high; a gear-rack meshing form is adopted, and the gear rotates by a corresponding angle when the racks move by a certain distance, so that the indexing efficiency is high.

Description

technical field [0001] The invention relates to a quick dividing head. Background technique [0002] The dividing head is an auxiliary device widely used in metal cutting machine tools such as milling machines, drilling machines and grinding machines, and is used to clamp the workpiece and make the workpiece rotate and index. The traditional indexing head is mainly composed of a base, a spindle box, an indexing disc, an indexing handle, and a main shaft. The workpiece is fixed on the chuck and driven by a worm gear mechanism. Indexing handle for indexing. Due to the gap between teeth in the transmission of the worm gear mechanism in the traditional indexing head, the accuracy of the indexing is not high, and the worm wheel rotates a certain angle after several turns of the worm, and the indexing efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fast dividing head with high indexing efficiency...
