Problems solved by technology

Since there is no special adjustment equipment, it has always been a difficult problem to adjust the indexing error of the angle measuring equipment. When adjusting the eccentricity, it can only be adjusted by feeling. Every time it is adjusted, the shell and the polyhedral prism need to be reinstalled for inspection; the adjustment of an indexing eccentricity requires repeated dismantling, installation and testing, and the efficiency is low. , and the final adjustment effect is difficult to meet the precise requirements

Embodiment 1

[0079] The invention provides a method for adjusting and repairing the indexing error of angle measuring equipment, which is characterized in that: the method for adjusting and repairing the indexing error of angle measuring equipment:

[0080] 1) The influence of eccentricity on the indexing error of angle measuring equipment

[0081] When the dial used as the angle measurement standard is installed on the main shaft of the angle measurement equipment, it often happens that the circle center of the scale line does not coincide with the rotation center of the instrument shaft system, such as figure 1 . If the center of the graduation line of the dial is O, the center of rotation of the shaft system of the instrument is O', the length of the eccentricity is represented by e, the direction of the eccentricity is at the position of the graduation line p, and the angle value of the p graduation line to the 0° graduation line is φ p .

[0082] When O and O' do not coincide and ha...

Abstract

The invention relates to an adjusting method for a division error of angle measuring equipment. In order to adjust an eccentric error, a scheme of diameter observation and adjustment is employed. A line connecting direction from 0 degree to 180 degrees is aligned and a dial is adjusted at a line connecting direction of scale lines of 90 degrees and 270 degrees, so that no deviation between the dial plate center and the main shaft rotation center exists. The dial is rotated by 90 degrees and is adjusted according to a line connecting direction of scale lines of 90 degrees and 180 degrees, so that the dial center and the main shaft rotation center are overlapped completely. Calibration is carried out by using a standard polygonal prism and an autocollimator; if the precision does not meet a measurement requirement, adjustment is carried out repeatedly by using the method until the measurement precision meets a using requirement of angle measuring equipment. The method has the following advantages: the operation is simple and convenient; the method is easy to adjust and operate; the measurement precision can reach a best state; the using state of the method is stable; the market demand is large; the data are stable and reliable; the adjustment precision can reach 3''; and the expected using requirement of the conventional angle measuring equipment can be met.

Description

technical field [0001] The invention relates to the field of measuring equipment calibration, in particular to a method for adjusting and repairing the division error of angle measuring equipment. Background technique [0002] The indexing plate and the indexing head are the main measuring equipment for measuring the angular size of parts or standard parts. Among them, the indexing plate is an essential and important component of the angle measuring equipment. The principle of angle measurement is to compare the measured angle with the standard angle of the dial and the resulting actual angle value. The dial is generally fixed on the main shaft or shaft sleeve of the goniometric equipment, and the readings are output through optical or digital display components. [0003] Whether the accuracy of the angle measuring equipment is accurate or not depends mainly on two error indicators, one is the marking error of the dial, and the other is the degree of coincidence between the...
