Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a radome opening tooling. Background Art

[0002] As a structure used to protect the antenna system from the external environment, the radome can effectively improve the performance stability and service life of the antenna system. As it is widely used in communications, aerospace, national defense and other fields, its demand is also increasing.

[0003] As shown in the figure, the radome 100 includes a cover body 101 and a flange 102 arranged at the edge of the cover body 101. The cover body 101 and the flange 102 need to be opened with a cover hole 103 to be assembled and connected with the antenna system. The traditional radome 100 uses a machine to open the hole, which takes a long time to process. The machine consumes a lot of energy and also requires experienced workers to operate skillfully to ensure the opening accuracy, which leads to a relatively high cost of machine opening the radome. In order to solve the above problems, we propose a low-cost radome hole opening tool. Utility Model Content
