Abstract

The invention provides a special-shaped hobbing cutter for machining a gear shaving cutter and belongs to the technical field of machining cutters. The special-shaped hobbing cutter can be used for solving the problems that a cutter relief groove of an existing gear shaving cutter needs a drilling or slot milling process, and the machining is troublesome. The special-shaped hobbing cutter for machining the gear shaving cutter comprises a cutter body with an axial inner hole, wherein a plurality of chip cutting cutter teeth are uniformly distributed in the circumferential direction of the cutter body, the side parts of the chip cutting cutter teeth are provided with chip cutting blades which are designed by adopting transposition and used for machining involute profile of the gear shaving cutter, the tops of the chip cutting cutter teeth are provided with groove cutting cutter teeth which are protruded outwards along the radial direction of the cutter body and used for machining the cutter relief groove of the gear shaving cutter, the tips of the groove cutting cutter teeth are in a shape of a circular bead, and the side cutting edges of the groove cutting cutter teeth are tangent to or intersected with the bottom of a chip containing groove to be machined. The special-shaped hobbing cutter has the advantages of high machining accuracy and machining efficiency, convenience in machining and the like.

Description

technical field [0001] The invention belongs to the technical field of processing cutters, and relates to a hob, in particular to a special-type hob for processing shaving cutters. Background technique [0002] With the rapid development of modern high-tech, gear technology has also made great progress, especially in recent years, in order to comply with the development trend of modern mass production, gears are developing towards high precision, long life, low cost and other trends. In the prior art, two steps are required to process the gear: firstly, the tooth profile of the gear is processed by a pre-shaving gear hob, and then the machined tooth profile is finished by a gear shaving cutter. The tooth surface of the shaving cutter has a row of chip pockets and the tooth surface forms a cutting edge to add gears. The chip pockets are generally processed by slotting, and the tooth root of the shaving cutter needs to have a relief groove to ensure the machining of the slotti...
