Abstract
The utility model provides a shaft rotation angular accuracy calibration auxiliary device with an adjusting function and relates to the technical field of the shaft rotation angular accuracy calibration auxiliary device. A special connecting base divides a common connecting device into an upper portion and a lower portion. Connecting bolts and adjusting bolts are disposed on a junction surface of two portions so as to meet the adjusting requirement that a standard polygon body is perpendicular to the axis of a shaft to be measured. Consequently, precision calibration operation can be smoothly carried out. At the same time, measuring accuracy of an accuracy measuring device is improved.
Description
Technical field
The present invention relates to a servicing unit technical field of rotation angle precision calibration.
Background technology
In the air navigation installation, commonly used to this precise part of laser gyro in order to improve navigation accuracy.And the laser gyro cavity need be used the accurate visualizer of five dimensions in processing detects.The accurate visualizer of five dimensions could use after should be respectively the rotation angle precision of the displacement accuracy of X, Y, Z direction and Y axle and Z axle being calibrated before using.The rotation angle precision calibration of axle is by installation code rib body on measured axis, through the precision of standard rib body examination examination rotation angle, provides the rotation angle precision of measured axis.Usually installation code rib body is accomplished connection through the step axle on the measured axis, because the step axle is not have regulatory function, is difficult to satisfy the adjustment requirement of the axis normal of standard rib body and measured axis before the close adjustment.
Summary of the invention
The objective of the invention is: in order to satisfy the adjustment requirement of standard rib body and the axis normal of measured axis before the close adjustment, a kind of axle rotation angle precision alignment aid of special proposition with regulatory function.
Technical scheme of the present invention is: a kind of axle rotation angle precision alignment aid with regulatory function; As depicted in figs. 1 and 2; It is to be made up of with 2 on the step axle that links to each other with standard rib body the step axle 1 that links to each other with measured axis, and is connected as a single entity through coupling bolt 9; On step axle 1 and the other end that measured axis links to each other, on through the cross curve in the center of circle, equally spaced have four tapped connecting holes 13 with the center of circle; The center of step axle 2 links that link to each other with standard rib body is provided with a tapped fixed connection hole 4; The circle such as end face of the other end end face that step axle 2 links to each other with standard rib body and the step axle 1 that has connecting hole 13; And have four unthreaded holes 5 with the corresponding position of connecting hole 13; Have four tapped adjustment holes 6 in the outside of four unthreaded holes 5, adjustment hole 6 is in order to be provided with the adjusting bolt 10 that is complementary with its internal thread; Four coupling bolts 9 screw in four tapped connecting holes 13 through four unthreaded holes 5 respectively is connected as a single entity step axle 1 and step axle 2.
The present invention has the following advantages: the application of the axle rotation angle precision alignment aid of band regulatory function of the present invention; Satisfied the adjustment requirement of the axis normal of standard rib body and measured axis before the calibration; Make calibration operation smooth, also improved the measuring accuracy of precision checking equipment simultaneously.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the connection stereographic map that the present invention is applied to the accurate visualizer Z axle test of optics five dimensions.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
In the accurate scopic use of five dimensions; When the rotation angle precision of Z axle is calibrated; As shown in Figure 3; In the middle of the platform of the L type rotatable parts 7 on the accurate scopic moving-member of five dimensions, be provided with Z axle 6, the step axle 1 of the axle rotation angle precision alignment aid of the band regulatory function of the present invention that at first will assemble inserts in the measured axis 6, the cover access standard rib body 4 in the junction of the step axle 2 that links to each other with standard rib body; Lay the circular cover 12 that has center pit, through the center pit of circular cover 12 and the tapped connecting hole 4 of step axle 2 tops setting standard rib body and step axle 2 are connected as a single entity by set bolt 11; Then, regulate bolts 10 through four and adjust, make after the axis normal of standard rib body 4 and tested Z axle, begin the calibration operation of the axle rotation angle precision of Z axle again.
