The design of demountable modular milling attachment based on engine lathes

This paper analyzes the limitation of engine lathes during manufacturing process because of its structural constraints, and designs the demountable modular attachment based on engine lathes. According to the analysis of the cutting process, an appropriate cutter drive servo motor is selected. Combined with the transmission range of tool rotational speed, transmission program is made and its parameters are determined. According to the transmission program, the actual tool change request and mounting dimensions of engine lathes, this paper designs and optimizes the structure of the power transmission device and the tool change device. Eventually the milling attachment is mounted to the engine lathe by the connecting device, reaching the demand of optimizing the working range of the engine lathe, realizing the turn-milling machining and raising fabrication efficiency and accuracy.
