下图为普通立式加工中心工作台部分的俯视示意图。工作台上依次摆放着9个相同的夹具。随着工作温度的升高,丝杠将受热伸长,最终影响工件与定位相关的位置精度。请问:几号夹具上的工件受热变形影响最大?几号夹具上的工件受热变形影响最小?为什么?公布第7期答案:答:双螺母结构的
The figure below shows the general vertical machining center table part of the top schematic. The workbench is followed by 9 identical fixtures. As the working temperature increases, the lead screw will be heated and extended, which will eventually affect the position accuracy of the workpiece and the positioning. I ask you: What is the greatest impact on the number of fixture on the workpiece by the deformation of the heat? The number of fixture on the workpiece by the deformation of the least affected? Why? Release No. 7 Answer: A: The double nut structure
