Structural Design of Feeding Drive System in Machining Center
Abstract：CNC machine tools in the modern manufacturing industry plays an increasingly important role. This paper introduces the design idea and design process of feed center feed drive system. The design of the feed system and the design and calculation of the main screw and its support are introduced. And the feeding system was verified, and achieved the desired effect.
The machine is suitable for light industry machinery and other industries to improve productivity. Not only the position and trajectory of the tool to control, but also with automatic tool change and compensation function, with high strength, stiffness and shock resistance. The machining center is flexible and can be adapted to the commercialization of the product in the shortest possible time. The design of the processing center to be used host, CNC system, servo and drive systems and related parts of three parts. Based on the analysis of the previous research results, according to the technical requirements of indicators, the initial formulation of the program to refine, demonstrate, improve and summarize.
The feeding system of the machining center is responsible for the positioning and cutting of the linear axes of the machining center. The feeding system will affect the running status and accuracy of the whole machine. The design process should make feed stability and fast response characteristics. At the same time, there must be a reasonable control system, but also to drive components and mechanical transmission parameters of a reasonable choice, so that the entire feed system to work when the dynamic characteristics can match each other.
After the study, the paper has achieved the expected results, completed the processing center feed drive system design and calculation. At the same time, the CNC machine tool feeding system design method research also achieved certain results.
