Package combination of sewing machine base bored and the design
of the left overall machine tool spindle box
Abstract: The topic for the package combination of sewing machine base bored and the design of the left overall machine tool spindle box.To improve the machining efficiency and to satisfy the processing requirements, the combine machine-tool was designed for drilling and boring the body of the R180 diesel engine cylinder with three facing set. The focal point of this topic is the total design and the design of the right headstock. Basing on studying comprehensively the components in structure characteristic, processing spot and specification and so on, the overall design of the combine machine-tool was completed. Its concrete content is to finish three drawings (process components working procedure chart, engine bed relation dimensional drawing, processing schematic drawing) and the productivity computation card on the foundation of the overall plan. The key of this modular is the right headstock part design. Firstly ,On the basis of completing the total design of machine tool system, the driving route of the headstocks were drawn up. Then according to headstock primitive basis chart and the methods of optimization, the concrete transmission plan was determined, the cogwheels are disposed, the driving parameter were determined. At last, the structure of principal axis were designed and the strength of parts are checked such as the cogwheels and the axletree. Under the condition of satisfying the processing precision, the liquid operated sliding table is used for realizing the movement. This design uses the standard headstock. The headstock uses standard details. This modular mechanical tool has such advantages: high efficiency, low cost, high processing precision, easily operated and it reduces the worker’s labor intensity, and enhances the productivity.
