Abstract

With the rapid development of science and technology, the demand of national economic sectors more varieties, multi-function, high precision, high quality, high automation technology and equipment development and manufacturing, to promote the development of advanced manufacturing technology. Honing processing is one of the most commonly used way of inner hole surface treatment, in recent years, along with the market demand for oil cylinder and other products, how to find a economic and efficient inner hole precision machining method, many manufacturers are faced with the task. Grinding technology is one of the important areas, cuhk advanced manufacturing technology is implemented in modern mechanical manufacturing precision machining, the super close the most effective, the application of the most effective technology.

This design from the analysis of mechanical systems design tasks and goals, the composition of the mechanical system is introduced in this paper, configuration, between each component matching selection and structure design, and what issues should be considered when the overall design of mechanical system, the purpose is to cultivate students innovative structural design and the overall design ability, cultivating their comprehensive analysis and solve this major general engineering technical problem of ability to work independently, to strengthen the understanding of theoretical knowledge. First is the overall design of honing machine, the design mainly includes the main spindle box, honing head, shaft and belt transmission, hydraulic system and other parts of the design. For honing machine to do a simple introduction, and then for a major part of the honing machine to calculate and check the size. This design represents the general process of honing machine design.
