This topic design a rough milling automobile gearbox two end milling machine, hydraulic double combination of main machine combination overall design, spindle box and design and the design of hydraulic parts.
According to the structure characteristics of the automobile gearbox, machining parts and precision and surface roughness and productivity, determine the machine for double-position horizontal combination machine tools . Considered to the factor of the size precision, surface roughness, scrap removes and productivity and so on of the work piece, selects the Hard alloy not grind type surface milling cutter. According to work piece size, characteristic and its material choice cutting specifications; Because of the thick mill diesel engine cylinder body two sides, then the jig design use "two sells the localization at the same time", Manual clamps, an attire clamps processes the diesel engine to be mad the cylinder body two sides; according to will work receives the cutting force to calculate clamps the strength; again according to clamps the strength , choose the determination clamp the special-purpose part.
During the design, the standard parts are selected as far as possible, to reduced the production cost, increased the economic efficiency. This design may achieve the effects as fowllows: the modular milling machine and the jig can satisfy its the quality requirement at working status,it’s safe, and easy to service.
