Abstract
The title of this design is the formulation of end cover processing process and the design of special fixture for drilling 4-φ 9 holes. On the basis of mastering the function of the parts, the process of the parts is analyzed. Aiming at the given problems of the design, the fixture of the machine tool is mainly designed in the design. This clip is designed to ensure machining accuracy, production efficiency and easy operation for workers.
At the beginning of the design, I consulted the relevant data and the literature on machine tool fixtures at home and abroad, analyzed the structure and process of the parts while reading the drawing of the parts, made clear the selection of the rough reference and the precision reference, determined the machining allowance and the size of the blank, so as to determine the machining process of the parts and calculate the cutting parameters and working hours of each process. Finally, the fixture needed for this design is completed.
Key words: end cover; processing technology; drill 4-φ 9 hole;special fixture; fixture design; cutting parameter
