减速箱体因轴孔多,与轴承配合孔的表面要求高(R_01.6以上),如用标准机床加工,成本高、效率低.为了高效率高质量地加工出减速箱体,我们设计制造了精镗孔专用机床,并使用C620车床车头箱作主轴箱,收到了很好的技术经济综合效果。 1.结构分析与主参数的计算 (1) 结构分析:我厂生产的挤压机有12、18两个系列七个品种。单机箱体左、右外侧孔间中心距尺寸最大的是12系列90机型箱体(如图1)。该专机要满足不同机型箱体的加工需要,因此机床结构尺寸以能
Because of the large number of shaft holes and the surface of the bearing fitting hole (R_01.6 and above), the reduction gearbox is costly and inefficient in machining with a standard machine. In order to process the reduction box with high efficiency and high quality, we design and manufacture The fine boring machine, and the use of C620 lathe headbox for the spindle box, received a very good technical and economic comprehensive effect. 1. Structural Analysis and Calculation of Main Parameters (1) Structural Analysis: Extruders manufactured by our factory have two series of seven varieties of 12,18. Stand-alone cabinet left and right outside the center hole between the largest size is 12 Series 90 model cabinet (Figure 1). The special plane to meet the processing needs of different models of the box, so the machine structure to size
