Abstract

The invention relates to an adjusting device for an optical centering instrument. The adjusting device aims at solving the problems of low adjustment precision and inconvenient operation of the optical centering instrument in the prior art, realizing rapid and accurate adjustment of the translation amount and the inclination angle of the optical centering instrument in the optical centering processing process, and improving the efficiency of centering machining. The adjusting device comprises a four-dimensional adjusting mechanism, a connecting frame and a multitap frame, the four-dimensionaladjusting mechanism comprises an X-axis angle adjusting table, a Y-axis angle adjusting table, an X-axis translation adjusting table and a Y-axis translation adjusting table which are sequentially arranged from top to bottom, the lower end of the Y-axis translation adjusting table is connected with an upper end platform of a vertical lathe through the connecting frame, the upper end of the X-axisangle adjusting table is connected with the optical centering instrument through the multitap frame, and the optical centering instrument is located below the Y-axis translation adjusting table. According to the adjusting device, the optical centering instrument and the four-dimensional adjusting mechanism are connected together, and through adjustment of the four-dimensional adjusting mechanism,two directional translation and two directional angles of the optical centering instrument can be adjusted.

Description

technical field [0001] The invention relates to an optical centering instrument, in particular to an adjustment device for the optical centering instrument. Background technique [0002] The optical centering instrument is a commonly used instrument in the optical centering process. Its function is to ensure the accuracy of the optical centering process by monitoring the sway of the self-collimation image of the spherical center of the optical element. [0003] The centering processing of the large-aperture optical mirror group is generally carried out on a vertical lathe, and the optical centering device is suspended on the top of the lathe to monitor the self-collimation image of the center of the sphere. The entire centering process is as follows: [0004] 1. Place a circular plane mirror on the turntable of the lathe, and draw a crosshair in the center of the mirror. Adjust the position of the reflector to ensure that when the turntable rotates, the radial and end runo...
