Deep in the general machine tool, tool rigidity as bad, easy to lead in the deep processing of partial to the hole axis line skew the discharge of chip and tool cooling is also more difficult and is difficult to guarantee the required machining accuracy and surface roughness degree. And converted into a deep hole with lathe machines, because of its low cost and short manufacturing cycle, and more than one use (deep hole drilling, turning, deep hole boring and honing), etc, has been accepted by many manufacturers. This realization is the use of ordinary lathe processing deep hole, using Lathe plete processing of the hole. Converted into a deep hole machine tool lathe main machine and two major oil line. Machine mainly consists of a center frame, granted the three major oil players and coupling ponents。 The deep hole processing。 Scraps discharge of device iii 目 錄 主要符號(hào)表 1 緒 論 ............................................................... 1 研究背景 ........................................................ 1 國(guó)內(nèi)外發(fā)展現(xiàn)狀 ............................................. 1 深孔加工的發(fā)展 ............................................. 2 深孔的加工特點(diǎn) ............................................. 3 2 研究?jī)?nèi)容 ............................................................. 4 本課題研究的主要內(nèi)容 ............................................ 4 擬采用的研究方案 ................................................ 4 3 改裝總體設(shè)計(jì) .......................................................... 8 機(jī)床的改造 ...................................................... 8 運(yùn)動(dòng)方式的確定 ................................................. 10 4 DF 系統(tǒng) 設(shè)計(jì)理論 ...................................................... 11 DF 系統(tǒng)的分類 ................................................... 11 內(nèi)排屑 DF 系統(tǒng) ............................................. 11 外排屑 DF 系統(tǒng) ............................................. 11 DF 深孔鉆 ....................................................... 12 DF 深孔鉆的特點(diǎn) ........................................... 12 DF 深孔鉆的使用 ................................................. 12 對(duì)加工系統(tǒng)的要求 .......................................... 12 切削用量的合理選擇 ........................................ 14 提高加工精度的措施 ........................................ 15 5 改造裝置 ............................................................. 16 中心架 ......................................................... 16 局部滾動(dòng)式中心架 .......................................... 16 整體滾動(dòng)式中心架 .......................................... 16 授油器 ......................................................... 17 不旋轉(zhuǎn)式授油器 ............................................ 17 旋轉(zhuǎn)式授油器 .............................................. 17 聯(lián)接器 ......................................................... 18 典型結(jié)構(gòu) .................................................. 18 結(jié)構(gòu)設(shè)計(jì) .................................................. 19 iv 6 冷卻排屑系統(tǒng)的設(shè)計(jì) ................................................... 20 油路設(shè)計(jì) ....................................................... 20 冷卻排屑系統(tǒng)結(jié)構(gòu)設(shè)計(jì) ........................................... 21 深孔加工的切削液 ............................................... 21 切削液的機(jī)能 .............................................. 21 深孔加工切削液的選用 ...................................... 22 切削液的流量與壓力 ............................................. 22 切削液的使用與管理 ............................................. 23 油箱容積、 油泵壓力及流量的確定 ................................. 23 加工孔的工藝分析
