Abstract
With the development of China's industrialization and urbanization, the domestic equipment industry has developed by leaps and bounds, and the machine tool industry, as the core of equipment manufacturing industry, has attracted much attention. No matter in the status, output value, technology and market, machine tool industry has developed rapidly, but the international machine tool industry development powers such as Germany, Japan and other countries still have gaps. With the progress of Science and Technology, industrialization and urbanization in China, the machine tool industry has good prospects for development. In a wide variety of machine equipment, as one of the most widely used machine tools milling machines, for the machining industry to provide an essential boost. Milling machine refers to the main use of milling cutters on the workpiece to process a variety of surfaces of the machine, usually milling knife rotation movement as the main movement, workpiece and milling tool movement into the feed motion. Milling machine is a widely used tool, in all walks of life play an important role, it can machine various forms of flat and surface, key slot, flower key, gear, sprocket, etc. , it can complete a variety of machine tools can do the work, at the same time because the milling machine tools are many blades, a larger one-time processing range, so milling machine has a high production efficiency and a wide range of applications.
Although milling machine has a wide range of applications, but with the continuous upgrading of China's manufacturing industry, product processing and manufacturing accuracy requirements and efficiency requirements are constantly improving, so the traditional ordinary milling machine can not meet the needs of today's market, so for the ordinary milling machine CNC transformation in the fire, CNC transformation for the manufacturing industry to achieve automation, flexibility, integration has an important application significance, can greatly improve the efficiency of processing and manufacturing, and because of the introduction of CNC servo system, Processing and manufacturing product accuracy, quality, etc. have also been guaranteed, product performance is more stable, help China to accelerate the upgrading of the manufacturing industry, but also to improve the overall level of manufacturing industry, so the ordinary milling machine numerical control improvement, especially for the feed system to add servo drive system is particularly necessary, so that enterprises can ensure the minimum input cost on the basis of improving the accuracy and efficiency requirements of processing manufacturing, reduce the pressure of enterprises, improve competitiveness. Based on the basis of the X6140 model milling machine, this topic is based on the improvement of the mechanism, the design of a small universal milling machine, the design of this topic of small universal milling machine structure contains the machine's casting body, main drive system, spindle components, servo feed transmission system, workbench and other parts. The main transmission range of the main drive system of the milling machine and the structure of the main drive system, the structural design of the servo feed system, the design of the structure parameters of the spindle assembly, and the structure of the machine body are designed in detail.
Key words: milling; main drive system; principal axis
