Description

A flatness replica jig

Technical Field

The utility model relates to the technical field of flatness measurement, in particular to a flatness replicating jig.

Background technique

In the prior art, the jig for measuring the parallelism of two planes A and B is generally a magnetic base micrometer, which includes a magnetic base, a micrometer and a universal rod for connecting the magnetic base and the micrometer. When in use, the entire jig needs to be set up on one of the planes using the magnetic base, and then the micrometer is used to measure the other plane. However, when the distance between the two planes is too large or too small, the jig cannot be placed on plane A at one end while the micrometer at the other end is in good contact with plane B, which makes the above method not applicable. At this time, it is necessary to add an appropriate number of transition planes according to the distance between the two planes and the size of the parallelism measuring jig. For example, if two transition planes A1 and A2 are needed, the entire jig must be placed on plane A and plane A1 must be measured to obtain the parallelism a1 between plane A and plane A1. Then the jig must be placed on plane A1 and plane A2 must be measured to obtain the parallelism a2 between plane A1 and plane A2. Finally, the jig must be placed on plane A2 and plane B must be measured to obtain the parallelism a3 between plane A2 and plane B. Thus, the parallelism a=a1+a2+a3 between plane A and plane B is obtained. However, the above method requires multiple moves of the jig, which is cumbersome and increases the measurement error.

In order to solve the above problems, it is necessary to provide a replica flatness jig to copy the flatness of plane A onto the jig, so that the measurer can move the plane copied on the jig to the vicinity of plane B for parallelism measurement, and then use the parallelism between the copied plane and plane B to obtain the parallelism between plane A and plane B, so as to reduce the number of times the jig is moved, break the limitation of the spatial distance between the planes to be measured, improve measurement efficiency and reduce measurement errors.
