二十四孔鉆削機(jī)床及夾具設(shè)計(jì)

摘要  介紹了本次設(shè)計(jì)的主要目的，通過(guò)對(duì)組合機(jī)床方案的擬定的分析確定該組合機(jī)床應(yīng)采取單工位固定式夾具的臥式雙面機(jī)床的配置形式。通過(guò)對(duì)切削力、切削扭距、切削功率及刀具耐用度的分析選擇合理的刀具結(jié)構(gòu)。通過(guò)對(duì)被加工零件工序圖、示意圖、機(jī)床聯(lián)系尺寸圖的分析，確定機(jī)床的總體設(shè)計(jì)方案。專用夾具通過(guò)V型塊定位，液壓缸夾緊裝置，以減少輔助加工時(shí)間。通過(guò)選用可換鉆套，鉆套裝在襯套中，襯套則是壓配在夾具體或鉆模板中，鉆套由螺釘固定，以防止它在刀具加工時(shí)轉(zhuǎn)動(dòng)，便于鉆套磨損后可迅速更換以達(dá)到提高工廠生產(chǎn)效率的目的。

Drilling Machine And Fixture Design of 24-hole
Abstract  The main purpose of design, through the combination of machine tool programming analysis to determine the combination of machine tools should be taken to a single fixed-position horizontal fixture configuration of the form of double-sided machine. Of cutting force, cutting torque, cutting power and tool life analysis tool to choose a reasonable structure. Parts were processed through the process map, diagram, map machines contact size analysis, machine design program. Dedicated fixture through the V-block positioning, hydraulic cylinder clamping device in order to reduce processing time auxiliary. Through the selection can be set for drilling, drilling suite in the bush, the bush is press-fit the specific folder or in the drilling template, drill sets fixed by the screw to prevent it from turning in the processing tool, easy to wear diamond sets can be quickly replacement in order to improve production efficiency.
