The Design of Two-side Drilling Machine Overall and
The Left-side Headstock of The Two-bridge Shell
Abstract: Nowadays, the need of precision become much tight. Modular machine tool is more popular extensive for lower cost and good quality .It shows more advantages than special machine tool. Its purpose of the topic is to guarantee the size and position precision of the machined components, high-speed and efficiently accomplish the process of the hole of back bridge shell. I designed this modular machine tool. During the process of design, I referred to international and national data. In order to improve the working efficiency and product’s quality, the design of the two-side drilling machine overall and the left-side headstock of the two-bridge shell was done. By the process analysis’s characterizations , the methods and steps of the design of the modular machine tool, the designing system was made. The drawing of the part’s processes ,the schematic diagram of machining ,the relationship of the machine size and the card of the productivity were drawn. After that, the primitive chart for the design of the left-side spindle box was given out. The transmission routes were confirmed and the transmission parameter was made. The assembly diagram of the headstock was drawn. After the gears were arranged using the optimized design. The supplement processing diagrams of the front side and behind side plate were also made. The intensity of the axes and gears were checked. The machine can satisfy the requirement of the design and the controlling precision was wholly improved .I generally know the process of modular machine tool.
