Abstract

The invention provides an eccentric shaft machining tool and method. The eccentric shaft machining tool comprises a deflector rod assembly fixed on a machine tool, a hoop assembly fixed on the deflector rod assembly, a front grinder apex and a rear grinder apex, wherein the hoop assembly is used for fixing an eccentric shaft in the radial direction; the front grinder apex and the rear grinder apex are fixed on the machine tool and used for positioning the eccentric shaft in the axial direction; the deflector rod assembly is fixed on a disc chuck at the front end of the machine tool; the disc chuck drives the eccentric shaft to rotate for grinding through the deflector rod assembly and the hoop assembly in the rotating process. The eccentric shaft machining tool is simple in structure, low in cost, capable of being combined with a general machine tool for use, wide in application range and high in efficiency.

Description

technical field [0001] The invention relates to an eccentric shaft processing technology, in particular to an eccentric shaft processing tool and a method for processing an eccentric shaft using the eccentric shaft processing tool. Background technique [0002] The large eccentric shaft is the core part of the crank mechanism, and its equipment performance requires high dimensional accuracy of the parts. [0003] Large-scale high-precision eccentric shaft processing has always been a difficult point in the heavy machinery industry. Ordinary processing equipment cannot meet the requirements for dimensional accuracy and surface finish of the processed parts. Generally, in heavy industries, special machines (special machine tools) or additional configurations are added to the machine tools. Heavy and other forms are processed, the processing cost is expensive, and the processing efficiency is relatively low. Moreover, if counterweight is added to the machine tool, the accuracy...
