根据产品零件的技术要求,选择合理的加工方法,才能保证产品质量,提高生产效率。 图1为某一产品零件的示意图,要同时保证槽1.7~(?)对孔φ1.5_(?)的垂直度和轴φ4.5_(?)的对称度要求是比较困难的。其加工方法有以下几种:其一是以φ1.5_(?)定位,φ4.5_(?)定向来磨槽1.74~(?),从图1的标注来看这样加工也是比较合理的。但因孔φ1.5_(?)太小,零件定位后无法夹紧固定,所以这一方法实现不了,其二是以φ4.5_(?)
According to the technical requirements of product parts, select a reasonable processing methods, in order to ensure product quality, improve production efficiency. Figure 1 is a schematic view of a product part, at the same time to ensure that the slot 1.7 ~ (?) On the hole φ1.5_ (?) And the vertical axis φ4.5_ (?) Symmetry requirements is more difficult. The processing methods are the following: First, φ1.5_ (?) Positioning, φ4.5_ (?) Orientation to grinding slot 1.74 ~ (?), From the label in Figure 1 point of view such processing is more reasonable. However, due to the hole φ1.5_ (?) Is too small, the parts can not be fixed after positioning, so this method can not be achieved, the second is φ4.5_ (?)
