Abstract

The invention discloses a novel hob. The novel hob is characterized by comprising a worm body, wherein the worm body is formed by an internal layer and an external layer, a plurality of cutter teeth and chip grooves are evenly distributed in the external surface of the external layer, and are arranged alternately, the internal layer is provided with a plurality of positioning holes with different depths, the external layer is provided with raised positioning bars, the raised positioning bars can extend and retract, and the external layer is fixed on the outside of the internal layer through the cooperation between the raised positioning bars and the positioning holes. The structure of the novel hob is novel, the novel hob is convenient to manufacture and machine, the lengths of the cutter teeth can be adjusted during use, the novel hob is flexible and changeable, and accurate to cut, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a novel hob. Background technique [0002] A hob is a gear processing tool in which the teeth are arranged in a spiral along a cylinder or a cone. There are various types of hobs in the prior art, but their structures are mostly fixed and cannot be changed, and their scope of application is limited. Contents of the invention [0003] Aiming at the above technical problems, the present invention provides a novel hob, which is novel in structure, easy to manufacture and use, accurate in cutting and wide in application when used for processing gears. [0004] The technical solution adopted in the present invention is: a new hob, characterized in that it includes a worm body, the worm body is composed of an inner layer and an outer layer, and the outer surface of the outer layer is provided with a number of evenly distributed cutter teeth and chip removal grooves, The cutter...
