1、數(shù)字化制造技術(shù)課程設(shè)計(jì)說(shuō)明書(shū)題目“滑油泵蓋”零件建模與加工仿真 一、設(shè)計(jì)任務(wù)（1）分析滑油泵蓋的二維圖紙及相關(guān)技術(shù)要求，根據(jù)圖紙繪制三維模型。（2）加工此零件為大批大量生產(chǎn),考慮綜合因素設(shè)計(jì)零件技術(shù)機(jī)械加工工藝 規(guī)程。（3）利用軟件進(jìn)行數(shù)控加工及仿真2、 零件分析與建模 根據(jù)圖紙要求建立模型如圖1、2所示：圖1 零件某一單向視圖圖2 零件的正二等測(cè)視圖3、 機(jī)械加工工藝規(guī)程設(shè)計(jì)3.1 零件的工藝分析 本零件為滑油泵蓋，其主要作用是封閉滑油泵使其滑油泵傳遞動(dòng)力,使其工作.所以對(duì)密封性能要求較高。從模型上分析可以看出本零件主要是以孔系加工以及平面加工為主，因此決定在銑床和鉆床上進(jìn)行加工操作。毛坯采

2、用鑄造留出加工余量為3mm.，從而在毛坯中銑各端面和分別鉆出螺栓孔和螺紋孔，毛坯如下圖所示： 圖3 泵蓋毛坯圖圖4 泵蓋毛坯圖本零件需要加工的工序是分別左端12個(gè)30的孔端面和銑右端面，鉆2個(gè)12的螺紋孔，2個(gè)10.5的通孔，12個(gè)17的螺栓通孔、用銑刀加工出85和95腔孔、鉆出2個(gè)17和2個(gè)40的錐形孔，用銑刀加工M10孔端面，鉆8.5孔，加工出M10螺栓孔，由于85孔和95孔比較大，故在鑄造中鑄出80孔。3.2 基準(zhǔn)的選擇定位的選擇是工藝規(guī)程設(shè)計(jì)中重要的工作之一。定位選擇得正確與合理，可以使加工質(zhì)量得到保證，生產(chǎn)率得宜提高。1、粗基準(zhǔn)的選擇：因?yàn)楸蒙w箱體類零件，執(zhí)照“保證不加工表面與加工表

3、面相互精度原則”的粗基準(zhǔn)選擇原則（即當(dāng)零件有不加工表面時(shí)，應(yīng)以這些不加工表面作為粗基準(zhǔn)；若零件有若干個(gè)不加工表面時(shí)則應(yīng)與這些加工表面要求相對(duì)精度較高的不加工表面作為粗基準(zhǔn)），所以對(duì)于本零件可以先以左端面部分作為粗基準(zhǔn)。2、精基準(zhǔn)的選擇：精基準(zhǔn)的選擇應(yīng)主要考慮基準(zhǔn)重合問(wèn)題。當(dāng)設(shè)計(jì)基準(zhǔn)與工序基準(zhǔn)不重合時(shí)，應(yīng)改進(jìn)行尺寸計(jì)算。應(yīng)選擇右端面為本零件的精基準(zhǔn)3.3 零件表面加工方法選擇及余量的確定 本零件的加工面有內(nèi)孔、端面、鉆孔等，材料為HT200.其加工方法選擇如下：各加工面的加工方法加工表面刀具余量加工方法右端面100銑刀3/0.5粗銑/精銑左端面30銑刀1精銑17孔17鉆刀實(shí)心鉆10.5孔10.5

5、主后次”原則，先加工主要表面，后加工次要表面，遵循“先面后孔”因此工序安排如下：工序1：粗銑-半精銑泵蓋右端面工序2：精銑泵蓋右端面工序3：精銑左端面工序4：鉆12個(gè)17孔工序5：鉆2個(gè)10.5孔工序6：絲錐功2個(gè)M12的螺紋孔工序7：鉆17錐形孔工序8：鉆40錐形孔工序9：銑2個(gè)85孔工序10：銑2個(gè)95孔工序11：銑M10端面工序12：鉆8.5孔工序13：絲錐功M10的螺紋孔工序14：去毛刺、清洗。工序 15：終檢。3.5 確定裝夾方案和選擇夾具 由于該滑油泵蓋零件形狀比較規(guī)則，所以在銑床和鉆床上只要用常規(guī)的定位夾緊件即可以保證其定位精度的要求。4、 UG的數(shù)控仿真加工 圖4.1 粗銑右端
