Knife tool for processing gear ring

Abstract

The invention provides a cutting tool for processing ring gear, which comprises a columnar cutting section (1) with a front handle (2) at one end and a rear handle (3) at the other end, wherein the cutting section (1) is integrated with the front handle (2) and the rear handle (3); a clamping handle (4) is arranged on the end head of the front handle (2); and a multi-ring cutting blade (5) is distributed on the surface of the cutting section (1). The cutting blade of the cutting tool is a spiral double-angle milling cutter, so that the cutting blade has an inclination angle to achieve thin cutting and prevent scratching workpiece surface, thus reducing deformation resistance, reducing cutting heat, preventing the formation of built-up edge, prolonging the service life of the cutting tool, improving the processing accuracy, achieving good processing effect, and preventing deformation of the processed product. Additionally, the cutting tool can simplify the processing procedure and reduce the production cost. The cutting section is a split hierarchical structure, which can satisfy different processing requirements to achieve wide application range.

Description

Technical field [0001] The present invention relates to a tool for processing a ring gear, particularly a tool for processing the ring gear of a planetary gear reduction mechanism. Background technique [0002] The structure of the ring gear of the current planetary gear reduction mechanism is an internal gear structure, and its diameter is relatively large. If the broaching method is used, the processing procedure is more complicated, the processing cost is relatively high, and errors are prone to occur during the processing. Coupled with heat treatment deformation, the processed product is prone to noise. Summary of the invention [0003] The invention provides a tool for processing a gear ring, which not only has high processing precision and good processing effect, and can meet the design requirements. [0004] The present invention adopts the following technical solutions: a tool for processing a gear ring, which includes a cylindrical cutting part, one end of the cutting p...
