Processing method and apparatus for rack

Abstract

A rack machining comprises drilling on the blank, cutting slot along the tangential line of the hole, milling the gear slot to form the rack, with less grinding effort and machining time with improved machining efficiency. The rack machining equipment comprises a machine base, working bench along the X axis in action, vertical post along Y axis, beam fixed with the post, No.2 milling device on the said beam along the Z axis in motion, with the second milling device composed No.2 generator, rotor shaft of the No.2 generator connected with No.2 gear box in motion, No.2 milling tool wit same output shaft and connected with the No.2 gear box, with the axle line of the output shaft of the No.2 gear box having a inclination angle of 20 degree with the said working bench.

Description

technical field [0001] The invention relates to a processing method of a rack and a device for implementing the processing method. Background technique [0002] In the prior art, the processing method of the rack uses milling cutters of different standards to directly grind the raw materials. For the rack with small modulus, this processing is relatively simple and convenient; but when the modulus of the rack increases , it is not suitable to use the milling cutter to directly grind into teeth, so people usually plan the rack blank by planing with a planer, but because the entire tooth shape needs to be planed out, the amount of planing will become very large Large, the time required for simultaneous processing will become very long, and when milling the planed rack, the traditional milling cutter is stressed on three sides, which requires a relatively high torque output of the machine tool. It is also quite large, and if the tool that wears to a certain extent continues to...

[0002] In the prior art, the processing method of the rack uses milling cutters of different standards to directly grind the raw materials. For the rack with small modulus, this processing is relatively simple and convenient; but when the modulus of the rack increases , it is not suitable to use the milling cutter to directly grind into teeth, so people usually plan the rack blank by planing with a planer, but because the entire tooth shape needs to be planed out, the amount of planing will become very large Large, the time required for simultaneous processing will become very long, and when milling the planed rack, the traditional milling cutter is stressed on three sides, which requires a relatively high torque output of the machine tool. It is also quite large. If the tool is worn to a certain extent and continues to be used for the processing of the rack, it is easy to cause the rack to fail to meet the required processing requirements.
