我厂过去在车削8类中小型轴承套圈外圆与沟道时,采用如图1所示的夹具.采用这种夹具常常会遇到这种情况:当需要加工内孔尺寸相同而直径系列不同(例如3106、8206、8306等)的零件时,操作者必须增加更换和调整夹具的时间.后来我们设计制作了如图2所示的夹具,遇到上述情况,操作者只须更换定位环4就可以了.改进后的夹具,不但提高了劳动生率,而且夹具的管理也规范化了.
In the past, when turning the outer circle and channel of 8 types of medium and small bearing rings, I used the fixture shown in Fig. 1. Such fixture often encountered this kind of situation: when the inner diameter and the diameter series Different parts (such as 3106,8206,8306, etc.), the operator must increase the time to replace and adjust the fixture. Later, we designed the fixture shown in Figure 2, in the case of the above, the operator only need to replace the positioning ring 4 on it. Improved fixtures, not only improve the labor productivity, and fixture management is also standardized.
