多轴箱体的孔与孔中心距的测量方法一般是在被测两孔中配入相应的检验棒,并伸出孔端面,然后使用千分尺测量伸出的两试棒之间的尺寸,减去(或加上)两试棒的半径值,即为两孔中心距值。采用这种检测方法,由于检验棒的尺寸误差和形状误差,操作人员的技术水平都会影响到测量结果,况且测得值是两试棒延仲位置数值,所以存在较大误差。此外还需制作各种规格的一次性试棒,增加了检测成本。
Multi-axis box hole and hole center distance measurement method is generally assigned to the two test holes in the test rod and stick out the end face of the hole, and then use the micrometer to measure the size between the two test sticks, minus To (or plus) the radius of the two test rods, the distance between the two holes. Using this test method, due to the size of the test rod error and shape error, the technical level of the operator will affect the measurement results Moreover, the measured value is the value of two test rod delay position, so there is a big error. In addition to the need to produce a variety of one-time test stick, an increase of testing costs.
