Abstract

A method for processing hole coaxiality of special-shaped box parts of a gear hobbing machine, comprising the following steps: first processing a tool holder to ensure that the steel guide rail of the tool holder is qualified; installing a nut holder on the tool holder, and presetting the holes on the nut holder. Machining, the aperture formed by pre-processing is 1-5mm smaller than the design aperture; the base is processed well, and the coaxial through holes at both ends of the base are processed to ensure that the coaxiality of the two holes meets the technical requirements; the nut bracket, the base 1. The tool holder is combined through the guide rail of the tool holder; the hole on the nut holder is finished, so that the size and surface quality of the hole on the nut holder meet the technical requirements. The invention can ensure the coaxiality without causing parts to be scrapped; only two bushings and one boring bar are required for the tooling, the installation and use are simple and convenient, no special boring tools need to be designed and manufactured, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing hole coaxiality of special-shaped box parts of a gear hobbing machine. Background technique [0002] Gears are one of the most common parts in the mechanical field, and their application scenarios are diverse and in great demand, which puts forward requirements for high-efficiency production and processing of gears. Gear hobbing machine is a common equipment for high-efficiency manufacturing of gears, and its normal and reliable work is extremely important. The accurate and quick installation of the hob in the gear hobbing machine has a great influence on the working efficiency of the gear hobbing machine, and one of the key components that affects the installation accuracy and efficiency of the hob is the tool holder. The various boxes that make up the tool holder components need to be connected by a screw, so there is a high requirement fo...
