The ordinary drill is a single drill. It will improve its productive efficiency, shorten its processing time if assembled a multiple spindle case on. That so calls a multiple drill. Hereby, the keystone of this design paper is how to design a multiple spindle heads. The design subjects include the selection and distribution of gear wheel, the design of spindle, and the guiding equipment and selection of the multiple spindle heads, etc. Key words: multiple drill; productive efficiency; multiple spindle heads :, :2000121316, : 1 1.1 15%85% 1.1.1 1500020842.5151.1171.61.930200040%20%1975 1.2 豸 豸 顣 1.2.1 .1:T2塣 1.2.2 Secto3230030060010506022.5Romai壬 迼123鵶45糬 1.2.3 絼1.2.4 (1) 棬 (2) 档46 (3) 档 (4) 1500020180黨5790黨8 1 3 豸 2 2.1 豸豸 2.2 2.2.1 1 1HT2005mmHBS170-240HBS10004- 6.7羫IT13.
