如何用補點(diǎn)銜接測量法檢定鑄鐵平臺度？

用自準直儀檢定鑄鐵平臺平面度時(shí)，自準直儀的放置應穩固可靠。其放置方法有兩種：一是安置在平板之外的專(zhuān)用支架或臺子上；二是安置在平板工作面上。由于以從儀器發(fā)出的平行光為測量基準，若安置不當，將產(chǎn)生較大的測量誤差。

前一種方法如采用不可調的專(zhuān)用支架，難以使橋板表面與支架表面等高，采用可調式支架調整也相當費時(shí)費事，因支架與被測平臺不為同一基準。然后一種方法則可實(shí)現基面統一，并且調整方便，找像容易。但自準直儀占據了平板的一定位置，不能測得平板全長(cháng)數據。采用補點(diǎn)法進(jìn)行數據銜接，可實(shí)現全長(cháng)測量。

When using the self-collimator to verify the flatness of the cast iron platform, the placement of the self-collimator should be stable and reliable. There are two ways to place it: one is placed on a special bracket or table outside the flat plate; the other is placed on the flat work surface. Since the parallel light emitted from the instrument is used as a measurement reference, if it is improperly placed, a large measurement error will occur.
In the former method, if a special bracket that is not adjustable is used, it is difficult to make the surface of the bridge board and the surface of the bracket high, and adjustment by the adjustable bracket is also quite time-consuming and troublesome, because the bracket and the platform to be tested are not the same reference. Then a method can realize the uniformity of the base surface, and the adjustment is convenient, and the image finding is easy. However, the self-collimator occupies a certain position of the flat plate, and the full-length data of the flat plate cannot be measured. The full-length measurement can be achieved by using the complementary point method for data connection.
