半轴轴线与主轴轴承安装孔端面的距离是变速器装配过程中需要控制的关键尺寸,操作者要根据每台变速器实测的数据确定调整垫片的厚度。为此,设计一套空间间距测量工装。该工装将两个空间位置通过有形的轴或端面表现出来,从而建立二者之间的计算关系。该方法操作简便,在生产工位上即可完成,无需进行三坐标检测,可节省大量成本和时间。
The distance between the half-shaft axis and the end face of the spindle bearing mounting hole is the key dimension that needs to be controlled in the transmission assembly process. The operator should adjust the thickness of the shim according to the actual measured data of each transmission. To this end, the design of a set of space measurement tooling. The tooling shows the two spatial locations through a visible axis or endface to establish the computational relationship between the two. The method is easy to operate and can be completed in the production station without the need of coordinate detection, which can save a lot of cost and time.
