Description
Technical Field
The utility model relates to a wheel rim detects technical field, especially relates to cubic unit wheel rim measurement reference block.
Background
The three-dimensional measurement means that a measured object is placed in a three-dimensional measurement space, the coordinate position of each measuring point on the measured object can be obtained, and the geometric dimension, the shape and the position of the measured object are calculated according to the space coordinate values of the points. The basic principle is that through the matching of the detection sensor (probe) and the movement of the measurement space axis, the discrete space point position of the measured geometric element is obtained, then through certain mathematical calculation, the analysis fitting of the measured point (point group) is completed, finally the measured geometric element is restored, and on the basis, the deviation between the measured geometric element and a theoretical value (nominal value) is calculated, so that the inspection work of the measured part is completed.
The reference block for measuring the rim in the prior art has a complex structure, is complex to operate when the rim is installed, has low working efficiency and can not achieve a good positioning effect.
SUMMERY OF THE UTILITY MODEL
