破碎机的关键件——大型偏心薄壁轴套的加工技术历来是国内外机械加工行业关注的重点,其加工时存在装卡易变形、测量困难及温升快等技术难点,因此,探索一种加工技术方法,对此类零件的加工有着非常重要的意义。1偏心轴套结构偏心轴套外形尺寸如图1所示,工件的尺寸公差6级,外圆对偏心内孔椭圆度为5级,外圆不圆度为5级,偏心轴套内孔的粗糙度为Ra0.4,其余粗糙
The key part of the crusher - large eccentric thin-walled bushings machining technology has always been the focus of the mechanical processing industry at home and abroad, the processing of its existence with easy deformation, measurement difficulties and temperature rise and other technical difficulties, therefore, to explore a Processing technology and methods, the processing of such parts has a very important significance. 1 eccentric sleeve structure eccentric sleeve outer dimensions shown in Figure 1, the size of the workpiece tolerance of 6, the outer cylindrical eccentricity of the ovate degree of 5, the outer cylindrical non-circularity of 5, the eccentric sleeve bore Roughness of Ra0.4, the rest rough
