气缸体关键工序是指决定发动机性能的、精度要求高、工艺性复杂的重要工序。这些关键工序的加工质量和精度决定着自动线的成败。因此,掌握这些工序的加工方法对研制综合自动化生产系统极为重要。本章将对气缸体的缸排面、底面、缸孔和止口、曲轴孔、曲轴止推面、曲轴半圆孔、轴承盖结合面和锁口面以及纵向油孔的加工分别作一介绍。(一)气缸体缸排面和底面的加工缸排面(直列气缸体即顶面,V型气缸体有两个)是与气缸盖相结合的平面,平面度为0.03～0.1/全长(600～800),它的加工质量对发动机的性能有很大影响。缸体和缸盖用螺栓连接,在高温和冲击力作用下工
Key cylinder block process refers to determine the engine performance, high precision, process complexity of an important process. The processing quality and accuracy of these key processes determine the success of automatic lines. Therefore, to master the processing methods of these processes for the development of integrated automated production system is extremely important. This chapter introduces the processing of cylinder block cylinder surface, bottom surface, cylinder hole and stop hole, crankshaft hole, crankshaft thrust surface, crankshaft semi-circular hole, bearing cap joint surface, lock surface and longitudinal hole. (A) Cylinder Cylinder The surface of the processing cylinder on the front and bottom surfaces (the top surface of the in-line cylinder body and the two V-shaped cylinder bodies) is the plane combined with the cylinder head with a flatness of 0.03 to 0.1 per full length 600 ~ 800), its processing quality has a great impact on the performance of the engine. Cylinder and cylinder head bolts, high temperature and impact under the work
