Integrated full metal reflection target ball

Abstract

The invention discloses an integrated full metal reflection target ball. The target ball is shaped in a ball with a groove, and the groove is provided with three faces which are perpendicular to one another. The target ball is integrated, when an environment temperature changes, a material of the target ball deforms integrally, decentration error caused by different dilatation coefficients of materials is avoided, influences of environment temperature change on the accuracy of measurement are reduced, and suitability for different working conditions is realized. The integrated full metal reflection target ball can be produced by only cutting off a triangular pyramid with edges as long as the ball radius and the three faces perpendicular to one another, extra assembling is not required dueto the fact that the target ball only has one part, surfaces of the three perpendicular faces are plated with fold films, and by plating the gold films on reflection faces, reflectivity of visible light waves can be increased.

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the target ball in the prior art is formed by separately making a reflector and a sphere, installing and embedding the reflector in the sphere, and then welding or bonding. Different materials have different material expansion coefficients, which lead to eccentricity errors. Now we provide an integrated all-metal reflective target ball to solve the above problems.
