The laser tracker has the characteristics of high precision, high efficiency, real-time tracking measurement, quick installation and the like. The laser tracker can be used for measuring a space target in real time by matching with the spherical reflector, and displaying the three-dimensional coordinates of the measurement target relative to the reference. The application of the laser tracker on the cold rolling mill unit mainly lies in the detection and adjustment of the central line offset of the housing of the mill stand and the detection and adjustment of the space state of the roll system. In the application of the laser tracker, the spherical reflector plays an important role, and the influence of the spherical reflector on the measurement precision is particularly great.

In a measurement site, a plurality of reference points are micro holes generated by sample punching and knocking, most of the reference points have the diameter of less than 1.5mm, and the diameter of the spherical radioactive mirror is 20-30 mm. When measuring, if the spherical reflector is placed on the reference hole with such a small size, it is extremely difficult to ensure that the center of the spherical reflector is on the same axis with the reference point. In the process of placing and positioning the spherical reflector, if the spherical reflector cannot be firmly attached to the detection surface or the center of the spherical reflector cannot be perpendicular to the reference point, for example, the equipment operation vibration, the self-weight displacement of the spherical reflector or the respiratory fluctuation of a measurer can cause the displacement of the spherical reflector, so that the measurement error is generated, the measurement precision is greatly influenced,

Detailed Description

In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.

As shown in fig. 1 to fig. 3, the utility model discloses a spherical mirror assistant measuring support adopts support 100 to place spherical mirror 600, is provided with the standing groove 200 of an indent at the center of support 100 to set up a measurement through-hole 300 in the center department of standing groove 200, measurement through-hole 300 link up support 100. In measurement, as shown in fig. 4 and 5, the support 100 is placed on the surface of the object to be measured such that the measurement through hole 300 is aligned with the reference point on the object to be measured, and then the spherical mirror 600 is vertically placed in the placement groove 200 of the support 100 such that the center line of the spherical mirror 600 is aligned with the measurement through hole 300, and the reference point on the object to be measured is aligned with the center line of the spherical mirror 600 through the measurement through hole 300.

As shown in fig. 1 and 2, the utility model discloses in the standing groove 200 that sets up adopts the circular recess, because spherical reflector 600 global be the arc surface, consequently will set up to curved inclined plane with spherical reflector 600 matched with standing groove 200 global, when making spherical reflector 600 vertically place in standing groove 200, spherical reflector 600 global can be laminated with standing groove 200 global mutually, guarantees the stability that spherical reflector 600 placed.
