Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] refer to figure 1 , a numerical control machine tool spindle cooling water jacket channel layout optimization design method, comprising the following steps:

[0048] 1) Construction of equivalent model: the selected water jacket entity is equivalent to have thermal conductivity λ 0 , and use this material as the material of the low thermal conductivity substrate in the model, with high thermal conductivity λ p The water jacket channel (that is, the cooling liquid) is grown and formed on the upper part of the base material;

[0049] Such as figure 2 As shown, for a certain spindle, the inner diameter of the water jacket covering it is the same as the outer diameter of the spindle. Here, the water jacket covering the spindle is divided into two sections for design, that is, half of the outer circumference of the spindle is the width ...

Abstract

A method for optimizing layout design of cooling water jacket channel of a CNC machine tool spindle is provided. The method comprises the following steps: the equivalent model is constructed first, and then the finite element model of the base structure is initialized, and the flexible growth unit is constructed, the finite element analysis is carried out, the adaptive growth is carried out, growth competition and configuration reconstruction are iterated under the updating of an MMA algorithm until the material consumption reaches the maximum value beta0 set when initialization. The inventioncan obtain the performance parameters of the water jacket through the finite element method in the design stage, improves the reliability of the design, has higher design efficiency compared with thetraditional design, can obtain better design results, and simultaneously reduces the design cost.

Description

technical field [0001] The invention relates to the technical field of water jacket channel design, in particular to a layout optimization design method for a cooling water jacket channel of a CNC machine tool spindle. Background technique [0002] The accuracy of the spindle is one of the most important factors affecting the machining accuracy of the workpiece. The loss and heat of the built-in motor in the spindle is inevitable, and the higher the load and speed, the more serious the heat and the greater the thermal deformation, and the thermal deformation has a great impact on the performance of the spindle. It has a great influence, which puts forward higher requirements on the thermal conductivity of the water jacket. [0003] The existing water jacket channel design still adopts the traditional method, that is, the designer relies on experience and intuition to make an initial design, and then corrects the initial design through multiple experiments. This design is in...
