The basic task of the designing was the machine design , mainly on ponent ’s working procedure chart , the processing schematic drawing , the machine relative dimensional drawing , the headstock assembly drawing , the engine bed jig as well as the important detail drawing plan . I could obtain the correlation data in the design process according to the actual situation , the reference pertinent data , absorbing predecessor ’s design experience and the exciting knowledge and making improvement according to reality and the knowledge which had grasped. The headstock isone of aggregate machine-tool ’s ponents , which carries on the design according to the specialized request , consisting of mon parts . Its main function is, according to ponents processing request , arranging various main axles position, and bequeathing the power and the movement by the electrical machinery or the power part to each work main axle , enable it to obtain set rotational speed and direction. Key word : Combination drilling machine, headstock, tongs. 充值下载即送 CAD 图纸, QQ 36396305 目录摘要...................................................................
