The design ability of machining process specification is one of the basic qualities that must be possessed by the scientific research and engineering technicians who are engaged in mechanical manufacturing. As a basic subject of higher engineering colleges, the design of machining process rules plays an extremely important role in practice. The role of process design in deepening the understanding of the basic theory of professional courses and strengthening the ability training to solve practical engineering problems is obvious.
This design is the design of gear shaft machining process specification. Although its structure is regular, but the accuracy requirements are relatively high, so the process requirements are relatively complex. It needs rough turning, fine turning, milling and pin grinding, of which fine turning is the key. Lathe processing technology is based on the basic theory of technology in mechanical manufacturing. Combined with the characteristics of lathe, it comprehensively uses various knowledge to solve the process problems in the process of lathe processing.
Process planning is an important process basis to ensure the high quality and low cost of mechanical products. Process planning is more prominent in machining. Therefore, the design of process planning for small and medium-sized parts is often selected as one of the main contents of graduation design.
Mechanical design is very important in mechanical engineering. It is an important link between theory and practice. This course design not only deepens our understanding of the theoretical knowledge with the textbook, but also organically combines the mechanical theory with the practical application and carries out in-depth practical training, so that the students can have a clearer understanding of the combination of theory and practice, laying an important foreshadowing for the future social experience, that is, training our design innovation ability and enhancing the mechanical design concept. The ability of machining process design is one of the basic qualities that the scientific research and engineering technicians engaged in the mechanical manufacturing specialty must possess. As a basic subject of higher engineering colleges, machining process design plays an extremely important role in practice. The role of process design in deepening the understanding of the basic theory of professional courses and strengthening the ability to solve practical engineering problems is obvious.
The reducer is an independent closed transmission between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the work needs. Gear reducer is widely used in all walks of life and is an indispensable mechanical transmission device. At present, there are many problems in reducer, such as large volume, heavy weight, large transmission ratio and low mechanical efficiency. Germany, Denmark and Japan are in the leading position of foreign reducers, especially in material and manufacturing technology. The reducers have good working reliability and long service life. But its transmission mode is still mainly fixed shaft gear transmission, and the problems of volume and weight have not been solved. The FA type high-precision reducer developed by Sumitomo Heavy Industry Co., Ltd. of Japan and the X-Y type reducer developed by Alan Newton company of the United States are similar to or similar to the project in transmission principle and structure, both of which are currently advanced gear reducers. Most of the domestic reducers are gear driven and worm driven. Gear shaft is a basic part of reducer, which plays an important role in modern life.
This design is the design of the gear shaft machining process specification. Although its structure is regular, but the accuracy requirements are relatively high, so the process requirements are relatively complex. The machining process of the typical parts is introduced, including the steps of blank – initial inspection – rough machining – finish machining, etc. the shape, structure, size and important matching parameters of the parts are added, and the three-dimensional modeling of the workpiece is completed. Determine the processing method and steps of parts, including the use of equipment, clamping method, fixture, processing orientation, tool selection, processing parameter selection, etc. Technological process is an important technological basis to ensure the high quality and low cost of mechanical products. Technological process design is more prominent in machining . The purpose of this design is to consolidate the basic theory and professional knowledge of process planning, and to replace the old relatively unreasonable process planning with new and more reasonable process planning. We are required to have a general and comprehensive understanding and grasp of mechanical manufacturing, master the basic laws of metal cutting process, master the basic knowledge of mechanical processing, select processing methods and machine tools, cutting tools, fixtures and processing parameters, have the ability to formulate process regulations, master the basic theories and basic knowledge of machining accuracy and surface quality analysis, and master the basic knowledge of machining accuracy and surface quality analysis The problems in the design process can be solved by browsing the references.
