ABSTRACT

This design is mainly about the double horizontal drilling boring machine design, through the combination of modular machine tool design, reach out three holes and one-time coarse boring hole two months out of a hole, thus ensure machining accuracy, improve efficiency and reduce labor intensity.

The graduation design is double horizontal drilling boring machine design, design combination of parts is rear axle housing. The main design is a card and three diagram spindle box. First the overall design of modular machine tool, then according to the workpiece material and hardness according to select tools, oriented structure, cutting dosages, cutting force and cutting torque and cutting power, and to select spindle shaft neck and the overhanging size, power components, hydraulic slider, and rendering process schematic diagram and the size of the contact. Based on the design of spindle box, spindle box is one of the main components of modular machine tool, according to special requirements for design, by general parts, its main function is to be processed parts, and will arrange the spindle position by motor sport motivation and the spindle or power components to get the required speed. According to the special spindle box processing characteristics, and its processing requirements for design, by a large number of special parts. The contents include: drawing design according to the design of the original spindle box. Determine the spindle structure, Determine the shaft neck and gear module, Transmission systems; worked Coordinate calculation, a transmission axis, Check, drawing coordinates, Spindle box layout drawing parts.

This design completed horizontal drilling boring machine, a combination of three diagram and left many, complete the design of crank shaft of spindle box left the position, meet the design requirements

KEY WORDS: combination machine tools, transmission system, left, with three spindle box
