Design of the General and Right Headstock of Modular Machine Tool for drilling Holes on Three-Side of the body of ZS175 Diesel Engine
Abstract: Machine is designed according to the standardization and serialization of generic components and parts are processed according to the shape and design of process-specific components of a dedicated machine. A Modular machine tool was designed for the ZS175 diesel engine with three-side drilling holes. Three horizontal machine used for processing program, processing and assembly process is good, spare parts to facilitate clamping. The focal point of this topic could be divided into two parts: the general design and the right headstock design. The general design includes the confirmation of the modular machine tool, the selecting of the structure type and the completing of the technological drawing of the parts to be manufactured, the general drawing of modular machine tool, drawing of cutter display and the efficiency card of manufacturing. Combination of machine tool spindle box is one of the important parts, according to special requirements of design, from the common parts of the fixture on the guiding device to ensure the accuracy of hole location processing. Its main role is to be processed in accordance with the processing requirements of parts, arrangement of the spindle position, and power and movement by electrical or power components to the spindle, so that it can be the requirements of speed and steering. Spindle box spindle box design includes mapping the original basis, the choice of spindle structure and dynamics, the spindle box drive system design and calculation, spindle box coordinates, the mapping coordinates inspections, shafts, gears, bearings, the school bond nuclear, spindle box before the design of the rear cover and cabinet. Combination of the smooth functioning of the machine, simple structure, reliable work, loading and unloading convenience, increased efficiency, to achieve the design requirements.
