Problems solved by technology

[0004] The special chamfering machine for the rounding and chamfering of spur gears is not suitable for the rounding and chamfering of spiral bevel gears in the aerospace field, and the existing manual grinding technology requires a high level of operator skills and requires skilled fitter, and the consistency of manual grinding is poor, and the processing quality is unstable. In addition, the efficiency of manual grinding is low, and the workload and labor intensity of manual grinding for gear parts that require mass production are large.

Embodiment 1

[0038] A gear rounding and chamfering milling method based on geometric self-adaptive compensation in this embodiment, the basic plan route is: complete the clamping of the gear parts under the rough reference, and combine the on-machine measurement to detect the actual clamping state of the gear parts and position, calculate the clamping error of the gear part according to the measurement data results, determine the angular position of the gear for the spiral bevel gear, adjust the machining tool path or machining coordinate system, and complete the milling of rounded or chamfered corners. The processing flow chart is as follows figure 1 Shown:

[0039] (1) Preparation before processing

[0040] The rounding and chamfering processing method of the spiral bevel gear in the present invention is a fixed contour milling process carried out under the five-axis numerical control machine tool, so relevant preparation work needs to be carried out before the machine tool is processed...

Abstract

The invention discloses a gear rounding and chamfering milling processing method based on geometric self-adaptive compensation, which completes the clamping of gear parts under a rough reference, combines with on-machine measurement to detect the actual clamping state and position of the gear parts, and according to the measurement data As a result, the clamping error of the gear part is calculated, the angular position of the gear is determined for the spiral bevel gear, the machining tool path or the machining coordinate system are adjusted, and the milling of the fillet or chamfer is completed. The present invention has the advantages of high machining efficiency and high machining accuracy. advantage.

Description

technical field [0001] The invention relates to the field of rounding and chamfering processing of gear tooth tops and tooth profiles, in particular to a gear rounding and chamfering milling processing method based on geometric self-adaptive compensation. Background technique [0002] As a key transmission component in aero-engines, spiral bevel gears have the advantages of high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high load-carrying capacity, reliable operation, compact structure, wear resistance, long life, and low noise. The rounding and chamfering of the tooth top and tooth profile of the spiral bevel gear are very important to the transmission performance and service life of the gear, and the technological purpose of the rounding and chamfering of the spiral bevel gear mainly includes eliminating sharp corners and sharp edges to prevent tooth alignment Surface scratches, reduce the noise and impact of gear transmission to im...
