Problems solved by technology

The disadvantage of this processing method is that the linkage is not strong, that is, if you change a certain size, you have to go back to Pro / E to modify it, and then go back to another program for operation, which is very inefficient and difficult to optimize the design.

Abstract

The invention relates to an emulation analytic method for a supportless grinding high rigidity main shaft system. The method comprises the following steps: based on three-dimension design software Pro / E, a three-dimension geometrical model is built to finish an assembly and form a digital prototype machine; seamless connection is realized by using submodule Pro / MECHANICA analyzing software of Pro / E; and in the submodule Pro / MECHANICA, a region is defined to restrict, load and contact, and the results of the stress and transfiguration of various relative parts are output after the calculation is performed. Considering various factors affecting the rigidity of the main shaft system, such as influences on contacting length between a core clamper and the center hole of a workpiece, the conicity of the center hole, the diameter of a bolt, arrangement mode, pretightening force, the conicity of a taper sleeve and magnitude of interference of the taper sleeve, the emulation analytic method provides a strong technical support for the design and manufacture of the supportless grinding high rigidity main shaft system with high performance.

Description

technical field [0001] The invention relates to a simulation analysis method for a spindle system, in particular to a simulation analysis method for a high-rigidity spindle system used for unsupported grinding. Background technique [0002] With the development of technology in the steel and automobile industry, efficient and high-precision grinding technology is becoming more and more urgent. Since the rigidity of the hydrostatic bearing is higher than that of the traditional roller bearing, the rotation accuracy is high, which is very beneficial to the processing of high-precision parts. On the other hand, the spindle system supported by traditional roller bearings must have a supporting mechanism when grinding workpieces due to insufficient rigidity. The grinding system using the support mechanism, in order to achieve high precision, must repeatedly grind, plus the adjustment time, the efficiency is very low. In order to achieve high precision and high efficiency, unsup...
