Problems solved by technology
After forced positioning and clamping, although the components seem to be assembled together on the surface, the internal stress of the parts themselves cannot be completely released and eliminated. In addition, the deformation of the composite parts that cannot be seen directly after being forced to assemble will cause damage to higher layers. Level assembly coordination brings greater deviation, and the service life and safety factor of parts will be greatly reduced
Each non-repeatable positioning assembly relationship, coupled with the lack of more complete inspection methods, puts the assembly quality of parts at risk, and lacks sufficient data support before delivery to ensure the uniformity and interchangeability of each part in each batch

The invention discloses an air pillow type multi-degree-of-freedom auxiliary positioning device for radome assembly. The device comprises an air pillow main body, a frame body, pressing strips, a rubber plate, a supporting panel and a bottom box body, wherein a rubber cavity is formed in the air pillow main body, the frame body is arranged on the periphery of the air pillow body, the pressing strips which are used for pressing the air pillow main body and are matched with the frame body are arranged on the frame body, the rubber plate with a circular hole in the center is arranged above the air pillow main body, the supporting panel is arranged below the air pillow main body, the bottom box body fixedly connected with the supporting panel is arranged below the supporting panel, the bottombox body comprises a frame, universal trundles arranged at the four corners of the bottom of the frame, and a compressed air pipeline assembly installed below the supporting panel. According to the invention, the radome can be freely and easily adjusted in six degrees of freedom, constraint deformation caused by forced clamping is eliminated, and possible damage to personnel and parts caused by using a crane is avoided.
Description
technical field [0001] The invention relates to the technical field of assembly aids, in particular to an air pillow type multi-degree-of-freedom auxiliary positioning device for radome assembly. Background technique [0002] With the development of modern high technology, radars are widely used in aircraft, missiles, navigation and other fields, and the use of radomes is also becoming more and more extensive. The radome is the window of electromagnetic waves. Its function is to protect the antenna and prevent the environment from affecting and interfering with the working state of the radar antenna, so as to reduce the power driving the antenna, improve its working reliability, and ensure the radar antenna to work around the clock. The existence of the radome prolongs the service life of the antenna, simplifies the structure of the antenna, and reduces the weight of the structure. The radome is an important part of the radar system, and its performance directly affects the...
