Even-gear input shaft deep hole grinding system and grinding method thereof

Abstract

The invention relates to an even-gear input shaft deep hole grinding system and a grinding method thereof. The even-gear input shaft deep hole grinding system is constituted by a clamp assembly and amachining assembly; the clamp assembly is composed of a clamp body, a clamping sleeve pulling rod and a self-centering elastic clamping sleeve; and the machining assembly is composed of a cooling liquid spraying pipe, a grinding abrasion wheel and a high-rigidity grinding rod. The grinding method of the even-gear input shaft deep hole grinding system comprises the following steps that A, parts ofan even-gear input shaft are loaded, and the shaft diameters of the two ends are clamped simultaneously; B, the even-gear input shaft is driven to rotate along the center line of the clamp body; C, the high-rigidity grinding rod drives the grinding abrasion wheel to the to-be-ground position, and meanwhile, the cooling liquid spraying pipe cools the to-be-ground position; and D, the high-rigiditygrinding rod drives the grinding abrasion wheel to rotate along the center of the high-rigidity grinding rod and feed in the radial direction to grind the parts. According to the even-gear input shaftdeep hole grinding system and the grinding method thereof, abnormal vibration of workpieces and the abrasion wheel is effectively reduced by using the self-centering elastic clamping sleeve and the high-rigidity grinding rod, the grinding quality is improved, and the burning phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of parts processing of DCT transmissions, and in particular relates to a deep hole grinding system and a grinding method for even-numbered gear input shafts. Background technique [0002] The even-numbered gear input shaft is a key part of the DCT transmission. Its deep hole is used as the contact surface of the needle roller bearing. It has the characteristics of deep position, small diameter, and high precision requirements. The traditional grinding device and method have poor machining rigidity and poor cooling effect. The workpiece is easy to burn, the grinding efficiency is low, and the grinding accuracy is not easy to guarantee. Contents of the invention [0003] The object of the present invention is to provide a deep-hole grinding system for even-numbered gear input shafts to address the above-mentioned deficiencies in the prior art. The object of the present invention is also to provide a grindin...
