Abstract

The invention discloses a tooth turning tool structure with a wear-resistant tool nose and a tool feeding method. A tooth turning tool is in a section gear shape and is provided with the tool nose and a tool body. The tool nose is fan-shaped and is made of a hard wear-resistant material. The tool body is made of a material with good toughness, impact resistance and machinability, and the tool body is rigidly connected with the tool nose. The edge curve of the tool nose is a section of space curve conjugated with the tooth surface of a workpiece, the tool nose is fed alternately along the tooth surfaces on the two sides of a tooth groove of the gear-shaped workpiece by combining a generating method and a tangent method, and compared with a traditional tooth turning tool and a tool feeding method, the tool nose has the advantages of being resistant to abrasion, low in use cost, resistant to impact and capable of restraining vibration, different modification machining requirements on tooth surfaces on the two sides of the gear-shaped workpiece can be flexibly met, and the device is further suitable for finishing a honing wheel.

Description

technical field [0001] The invention relates to the technical field of gear processing technology, in particular to a gear cutting tool structure and a tool feeding method with a wear-resistant tool tip. Background technique [0002] The gear turning process has good machining accuracy and high machining efficiency. It has unique advantages in the processing of internal gears, double-coupling gears, and worms, and is a hot spot in the development of the gear processing industry; [0003] Gear turning belongs to intermittent cutting and up-cut milling. During the cutting process, the cutting parameters of the cutter teeth change drastically. When the cutter teeth cut into the tooth groove of the workpiece, the working rake angle decreases rapidly, and even becomes The large negative angle, the drastic change of the cutting parameters of the gear cutting tool will seriously affect the tool life and the quality of the tooth surface, the tool tip is easy to be worn, and the mach...
