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.
