Problems solved by technology

[0003] The technical problem solved by the present invention: Aiming at the shortcomings of the existing spiral bevel gear processing method, a new spiral bevel gear processing method is provided, which can effectively reduce production costs, shorten production preparation time, broaden the processing range, and improve production efficiency
Especially solve the processing problem of large diameter spiral bevel gear
[0004] Design idea of ​​the present invention: In order to solve the manufacturing problem of single-piece small-batch and large-scale spiral bevel gears, the present invention uses CAM software to compile NC programs, and uses common rod milling cutters and angle discs to control five-axis linkage CNC machine tools through NC programs. Milling cutters can process high-quality spiral bevel gears

Embodiment Construction

[0014] A processing method for spiral bevel gears, using CAM software to compile NC programs, and then input the NC programs into the CNC of the five-axis linkage machining center, install the pre-adjusted tool on the main shaft, establish and set the workpiece coordinate system, input Tool parameters, start the execution button, the five-axis linkage machining center will execute X, Y, Z, C, B five-axis linkage actions according to the program instructions, and use ordinary rod milling cutters or disc-shaped angle milling cutters to complete the roughing of the tooth surface of the spiral bevel gear. machining or finishing.

[0015] The roughing or finishing sequence of the tooth flanks of the spiral bevel gear is done with a common rod milling cutter.

[0016] 1. Input all the parameters of the gear blank one by one according to the drawings, run the gear blank design module, and design the gear blank.

[0017] 2. Choose to run the screw umbrella roughing module based on th...

Abstract

The invention relates to a processing method for a spiral bevel gear which applies a CAM software to program an NC program and controls a five shaft link numerical control machine through the NC program to adopt an ordinary milling cutter to finish the rough processing or fine processing on the surface of the spiral bevel gear. The invention can effectively reduce the manufacture cost, shorten the manufacture preparing time, expand the processing range and improve the manufacture efficiency. The invention is in particular suitable for the processing of a big diameter spiral bevel gear.

Description

technical field [0001] The invention relates to a processing method of a spiral bevel gear, in particular to a processing method of a spiral bevel gear which does not require a special spiral bevel gear milling machine and can improve processing efficiency, reduce manufacturing cost and reduce preparation time. Background technique [0002] At present, there are three types of spiral bevel gear tooth shapes: Gleason, Olikon, and Klingenberg, and there are two types of contour teeth and shrinking teeth in shape. The manufacture of large quantities of medium and small-sized spiral bevel gears is processed on a special gear milling machine with several specific cutter heads for each variety. Although the processing efficiency is very high, there are still defects in the processing technology of the existing spiral bevel gear, so there are the following deficiencies in the use and implementation: first, the production preparation time is very long, and the initial investment is ...
