【正文】 d for blank check device also saves the rough quality problems due to waste of machining time, increase overall efficiency. Therefore, the refinement of rough is to improve the productivity of the most promising way out. For the engine block production line, can be rough in parts online premilling six face, removing most of the margin, to facilitate direct online parts. Machining process selection and processing of the benchmark Choose the right processing technology base is directly related to the processing quality can ensure the parts. Generally speaking, process benchmarking can be divided into coarse and fine reference base. Coarse reference base The baseline for the online thick rough ,which is particularly important the choice of benchmark crude, if crude benchmark choice unreasonable, will the uneven distribution of machining allowance, processing and surface offsets, resulting in waste. In the cylinder production line, we have adopted for the coarse side of the base。 second,finishing on the back,and will not damage during transport the surface of the workpiece has been processed。因此，機械加工工藝規(guī)程設計是一項重要的工作，要求設計者必須具有豐富的生產(chǎn)實踐經(jīng)驗和廣博的機械制造工藝基礎理論知識。 毛坯的選擇 變速箱殼體 采用的材料一般是灰鑄鐵 HT150、 HT200、 HT250，也有采用鑄鋁或者鋼板的，此發(fā)動機缸體采用高強度合金鑄鐵。 粗基準 粗基準對于上線的毛坯，其粗基準的選擇尤為重要，如果粗基準選擇不合理，會使加工余量分布不均勻，加工面偏移，造成廢品。在發(fā)動機缸體的機械加工中同樣 應遵循這一原則。在發(fā)動機缸體深油孔的加工中，采用槍 鉆工藝； 清洗 清洗分為濕式清洗和干式清洗。在缸體的加工中，采用側面和主軸軸承孔定位，頂面、底面和中間瓦蓋面同時加工，在加工中采用線外對刀裝置，能較好地滿足發(fā)動機缸體加工精度要求； 一般孔系的加工 一般孔系的加工仍采用傳統(tǒng)的鉆、擴、鏜、鉸、攻絲等工藝方法。因此，擬定工藝順序時，要抓住“加工精度高的表面”這個矛盾，合理安排工序和合理劃分加工階段。 機械加工工藝基準的選擇和加工 選擇合理的加工工藝基準，直接關系到能否保證零件的加工質(zhì)量。發(fā)動機缸體機械加工的工藝特點是：主要是平面和孔的加工，加工平面一般采用刨、銑削等方法加工，加工孔主要采用鏜削，加工小孔多用鉆削。 Detection Detect points outside the line detection and line detection of two kinds. Quality inspection in the engine block,according to the actual situation with lines outside the detection,the main use of coordinate measuring machine integrated measureme nts of the cylinder,each 200 samples 15 pieces,each class random one. 變速箱殼體 機械加工工藝設計 摘自： 《機械工程與技術（機加工）》（英文版） 機械工業(yè)出版社 2021 年 3 月第 1 版 p560— 564 美 s. 卡卡爾帕基安 施密德 摘要 變速箱殼體 是 變速器 機零件中結構較為復雜的箱體零件，其精度要求高，加工工藝復雜，并且加工加工質(zhì)量的好壞直接影響發(fā)動機整個機構的性能，因此，它成為各 個發(fā)動機生產(chǎn)廠家所關注的重點零件之一。In addition,if the main surface of a waste,these small the surface will not have to be processed,thus avoiding a waste of ,if the processing is very easy for a small surface bumps the main surface,it should be placed on a small surface finish prior to the mai n surface finishing。 Concentration process principle Focus on a key process in principle process the body cylinder bore, crankshaft hole, Balance Shaft hole surface finishing and the bination of precision milling cylinder head, using a process focused on a setup program to plete all pr
