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...

[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 applied to 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 sequence, and in order to measure the inner and outer sides of the curved reflector , it needs to be equipped with a manipulator to realize the flip, the transfer path is complicated, the equipment is complicated and the total area is large. Among them, the existing arc or angle measuring device, symmetry measuring device, and signal uniformity measuring device cannot be used to measure the arc at the same time. The inner and outer sides of the shaped reflector, the device structure is complicated, and the scope of application is small
