the Design of the Upright of the Bevel Gear CNC Milling Machine
Abstract：Along with the country to raise the level of industrialization, the spiral bevel gear transmission requirements more and more is also high. Therefore, the spiral bevel gear of digital integrated manufacturing, CNC technology is applied to production, whether in improving the quality of spiral bevel gear transmission, or expand the market demand has important significance. This paper introduces is CNC bevel gear gear milling machine column parts design. In the design of the main CNC bevel gear milling machine column parts of structure analysis and the structural strength of the check. Through the analysis in the design of the structure of the pillar mainly adopts frame structure, mainly for the shell and internal rib plate. Then the column the material choice, adopt the most suitable materials. On balance hydraulic balance method and weight balance method of comparison, the design of column balance method I used hydraulic balance method, hydraulic balance method for weight control post balance method is more convenient, and use hydraulic balance the proportion of hammer balance method when the error is smaller. When the intensity is the use of finite element to carry out the strength check.
