For further enhances the numerical control engine laths the processing efficiency, the numerical control engine laths is clamping to the work piece in an engine laths attire then completes the multi-channel working procedure or the complete working procedure processing direction develops, therefore appeared each kind of type processing center engine laths, ike the turning center, the boring mill processing center, drills truncates center and so on. This kind of working procedure processing numerical control engine laths must use many kinds of cutting tools in the processing process, therefore must have trades the knife installment automatically, also is the knife storehouse which said, in order to select the different cutting tool, completes the different working procedure the processing craft. Trades the knife equipment to have automatically to have trades the knife time short, the cutting tool repetition pointing accuracy high, the enough cutting tool margin, the area small, safe reliable and so on the characteristics. The present paper is the development designs one kind of volume slightly, the structure compact, the price is low, production cycle short small vertical processing center knife storehouse this article. Then further introduced this small processing center knife storehouse overall structure and various parts plan choice, and has carried on the small processing center knife storehouse mechanism design calculation in this foundation, mainly includes the knife storehouse overall organization design, the electrical machinery selection, the knife storehouse rotation detent mechanism design knife storehouse migration part design and so on.
