Embodiment 1
[0024] The verticality of the azimuth axis and the pitch axis of a certain type of land defense monitoring turntable requires an angle error of 42 "in the range of pitch -10°~+95°, so the axis system of the land defense monitoring turntable 1 is correct based on the method of the present invention. The devices involved in the measurement include land defense monitoring turntable 1, support base 2, mirror assembly, self-collimating light tube 6 and laser electronic theodolite 7, such as figure 1 shown;
[0025] Among them, the precision of the self-collimating light tube 6 is 10″, the precision of the laser electronic theodolite 7 is 2″, and the reflector assembly is assembled from tooling I3, tooling II4, and reflective mirror 5 in sequence, tooling I3 and tooling II4 The six hexagon socket head screws are installed together to form the effect of "three pulls and three tops", that is, the three hexagon socket head screws pass through the tooling II4 and the tooling I3 to conne...

The invention relates to a laser measurement method for orthogonality of a land defense monitoring turntable shaft system, and belongs to the technical field of orthogonal shaft system measurement ofprecision land defense monitoring turntables. According to the method, the consistency adjustment of a pitch axis of a land defense monitoring turntable and an optical axis of a quasi-parallel light pipe is realized by virtue of a tooling adjustment reflecting lens in a reflector assembly, then the consistency adjustment of the optical axis of a laser electronic theodolite and the optical axis ofthe quasi-parallel light pipe is realized by adjusting the orientation and pitching of the laser electronic theodolite, and then the pitching of cross light reflected by the reflecting lens observed by the laser electronic theodolite is finely tuned to obtain orthogonality data of a shaft system, multiple sets of shaft system orthogonality data can be obtain by changing the orientation of the landdefense monitoring turntable and repeating the operation, and an orthogonality error of the shaft system is obtained by taking a square root of an average value of sum of squares of the multiple setsof shaft system orthogonality data. The method provided by the invention is simple to operate and high in test precision, and can meet the detection of the orthogonality of turntable shaft systems ofdifferent precision and different outer dimensions.
Description
technical field [0001] The invention belongs to the technical field of measuring the orthogonal shafting of a precision land defense monitoring turntable, and in particular relates to a laser measurement method for the orthogonality of the shafting of a land defense monitoring turntable. Background technique [0002] With the rapid development of my country's land defense monitoring turntable, higher requirements are put forward for the axis accuracy of the turntable. In order to ensure that the land defense monitoring turntable can accurately find and track targets, it is particularly important to accurately measure the axis orthogonality of the turntable. [0003] The Chinese patent application (a method and device for measuring the orthogonality of the rotary shaft system) with the application number of 201510462936.0 introduces a method and device for detecting the orthogonality of the shaft system. There are certain limitations, and there will be large errors at the sam...
