Description

technical field

[0001] The invention relates to the technical field of antenna production, in particular to a device for detecting external features of a curved reflector. Background technique

[0002] In the production process of the antenna reflector, it is generally necessary to use a fixing device to fix it for the subsequent detection process. However, the existing fixing device is generally only suitable for fixing the flat reflector, and cannot be used for the curved reflector. If this kind of fixing device is directly used, it is very easy to cause deformation and damage to the curved reflector due to excessive extrusion in the subsequent process, or cause the curved reflector to shake due to uneven fixing force, which will affect the processing or testing requirements; secondly, If you want to perform radian or angle measurement, symmetry measurement, and signal uniformity measurement on the curved reflector, it must be transferred between multiple devices in sequen...
