【正文】 學(xué)解決的途徑。 普通機(jī)床經(jīng)歷了近兩百年的歷史。在我國(guó)香港等地 也有人叫旋床。 關(guān)鍵詞： 盤(pán)絲車床，盤(pán)絲， 平面車削 3 Abstract Threading lathe used for processing of three claw chuck parts plate wire, including car plane thread, facing and boring. The machine adopts the bed length direction and the axis of spindle vertical layout, with two knife. In this paper the design of the main design entry feeding mechanism, the feeding mechanism is mainly used for the turret top. Design of cutting feed mechanism design needs to meet, can drive the upper carriage for cutting motion, starting at the end of the screw motion must stop, when arriving at the entry end of stroke, upper carriage should return in situ. This paper mainly pletes the identified entry feed mechanism design, feeding mechanism is controlled by a hydraulic system, drive the piston, through the rack drives the gear, screw rod to rotate, so that, through the leading screw nut pair, the rotary motion into linear motion, realized the feed. On the main parts design calculation, such as gear and rack mechanism, the ball screw mechanism, a ratchet pawl, rocker, box and other parts of the design. Key Words: Threading lathe， plate wire， flat turning 4 目 錄 摘 要 ........................................................................................................................................ 2 Abstract....................................................................................................................................... 2 目 錄 ........................................................................................................................................ 4 第 1章 緒論 .............................................................................................................................. 6 車床簡(jiǎn)介 ...................................................................................................................... 6 數(shù)控車床的概念 ......................................................................................................... 6 車床的組成與各部件的安裝注意事項(xiàng) ...................................................................... 7 盤(pán)絲車床 ..................................................................................................................... 8 本文主要研究?jī)?nèi)容和任務(wù) ......................................................................................... 9 第 2章 切入進(jìn)給機(jī)構(gòu)總體設(shè)計(jì) .............................................................................................. 9 液壓系統(tǒng)設(shè)計(jì) ........................................................................................................... 10 液壓傳動(dòng)部分設(shè)計(jì) ......................................................................................... 10 盤(pán)絲車床的切入進(jìn)給機(jī)構(gòu)方案設(shè)計(jì) ........................................................................ 11 切入進(jìn)給機(jī)構(gòu)方案設(shè)計(jì) ................................................................................ 11 切入進(jìn)給機(jī)構(gòu)方案擬定 ................................................................................. 12 第 3章 切入進(jìn)給機(jī)構(gòu)工作原理 ............................................................................................ 12 第 4章 切入進(jìn)給機(jī)構(gòu)各零件設(shè)計(jì) ........................................................................................ 13 齒條和齒輪設(shè)計(jì)計(jì)算 ............................................................................................... 13 蝸輪蝸桿副的設(shè)計(jì)計(jì)算 ........................................................................................... 15 滾珠絲杠副的設(shè)計(jì) ................................................................................................... 19 滾珠絲杠的特點(diǎn) ............................................................................................. 20 滾珠絲杠副結(jié)構(gòu) ............................................................................................ 21 滾珠絲杠副的種類 ......................................................................................... 22 滾珠絲杠副精度 ............................................................................................. 22 滾珠絲杠副性能 ............................................................................................ 22 導(dǎo) 軌副設(shè)計(jì)與計(jì)算 ........................................................................................ 24 5 滾珠絲杠副設(shè)計(jì)與計(jì)算 ................................................................................. 25 棘輪機(jī)構(gòu)設(shè)計(jì) ................................................................................................ 29 棘爪零件設(shè)計(jì) ................................................................................................ 30 手動(dòng)進(jìn)給搖桿的設(shè)計(jì) .................................................................................. 30 進(jìn)給箱體的設(shè)計(jì) .......................................................................................... 31 總 結(jié) ........................................................................................................................................ 31 參考文獻(xiàn) ...................................................................................................
