Description

Technical Field

[0001] The utility model mainly relates to the technical field of optical point measurement, in particular to an optical point measurement fixture. Background Art

[0002] Currently, when measuring the optical point data of 3D products, two requirements need to be met. First, the product must be completely fitted with the lens of the optical measuring instrument to ensure the accuracy of a single measurement. Second, the points measured for this type of product must be the same to ensure the accuracy of batch measurements.

[0003] At present, the way to measure glass with optical point measuring instruments is to clamp the product with the chuck on the instrument so that the product fits the lens, thereby achieving the purpose of measuring the optical data of the point. However, it was found during use that when the chuck of the measuring instrument clamps the product, if no external force is used, the product will tilt or even fall, resulting in inaccurate measurement data or even damage to the product; and the measurement point will be different each time the personnel place it, resulting in a batch of products being measured. The point cannot be guaranteed to be the same. If multiple points on the same line are measured, it is even more difficult to ensure the accuracy of the measurement. As a result, the current measurement status can only guarantee the former, and this method will cause the error to become larger and the data is not accurate enough. Utility Model Content
