Method for processing harmonic reducer flexible wheel

Abstract

The invention discloses a method for processing a harmonic reducer flexible wheel. The method sequentially includes processes of blanking, forging and shaping, normalizing for heat treating, spinning, turning in a CNC (computer numerical control) lathe, gear-shaping in a CNC milling machine and punching and shaping. The process of punching and shaping is performed through matching of a punching machine and a punching and shaping die, an upper die base, an upper padding plate, an upper fixing plate, a lower die base, a lower padding plate, a lower fixing plate, an upper shaping die, a positioning column, a pressing plate, a tightening ring, a tightening-ring pressing plate and a locking screw are arranged on the punching and shaping die, and an inner shaping gear hole is formed in a core portion of the upper shaping die. The pressing plate clamps and fixes a fixed portion of the semi-finished flexible wheel, the positioning column, the tightening ring, the tightening-ring pressing plate and the locking screw cooperatively fix a center hole of the semi-finished flexible wheel, and the inner shaping gear hole performs shaping upon a profile of an outer gear portion. Therefore, flexible-wheel processing can be completed through a universal machine tool, financial burden of manufacturers can be reduced on one hand, and on the other hand, processing precision of the flexible wheel can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a processing method for a flexible wheel of a harmonic reducer. Background technique [0002] The robot harmonic reducer is widely used as an important part of the robot joint due to its advantages of simple structure, small size, low noise, large transmission ratio, high transmission precision and high efficiency. Since C.W. Messer in the United States invented the first harmonic reducer in 1955, major industrial countries all over the world have conducted comprehensive research on it, and have successively produced many series of harmonic reducers with different types and sizes. The involute small modulus gear tooth profile harmonic reducer is the most widely used. Among them, the harmonic reducer is widely used in the rotating part of the joint of the robot, the rotating table of the machining center, the rotating part of the manipulator, the precision rotating tab...

Problems solved by technology

[0003] For harmonic reducers, such as figure 1 As shown, the flexspline 1 generally includes a fixed part 11 and an external gear part 12 integrated with the fixed part 11. The teeth of the external gear part 12 are generally processed by expensive professional gear processing machines. To ensure the processing quality, professional Gear processing machine tools are generally outsourced, which brings a heavy economic burden to the manufacturer
