Abstract

The invention relates to a new type dividing head, comprising a box, a main shaft, a gear, a driving rack, a driven rack and a transition rack, wherein the main shaft, the gear, the driving rack, the driven rack and the transition rack are arranged in the box; the gear and the main shaft are fixedly connected; the driving rack is meshed with one side of the gear, and 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 rack, and the driven rack is meshed with the other side of the transition rack. By adopting the new type dividing head, the influence on dividing by the intertooth space between the gear and the racks is eliminated, and the dividing accuracy is high; a form of gear and rack meshing is adopted, the racks are moved for a distance, and the gear is rotated for a corresponding angle, and the dividing efficiency is high.

Description

technical field [0001] The invention relates to a novel 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 new type of dividing head with high indexing eff...
