Embodiment Construction
[0026] An antenna dismounting device for avoiding deformation of a waveguide cavity, comprising: a base plate 1, an antenna mounting frame 2 and a force component. The booster component includes: a bracket 3 , a rod 4 , a pressure head 5 , a booster nut 6 and a spacer 7 .
[0027] The antenna rack 2 is rectangular, and the curved surface groove at one end matches the peripheral size of the fuze frame. The axial center of the curved surface groove has a sinking groove. It is 0.5mm-2mm larger than the external dimension of the disassembled antenna; the other end and the curved surface groove form a step surface limit, the surface of the step surface has a through groove in the axial center, and the radial dimension of the axial center through groove on the surface of the step surface is larger than that of the rod 4 The width dimension and the depth dimension meet the travel range of the rod 4 when the antenna is disassembled. The antenna mount 2 is screwed to the bottom plate ...

Abstract
The invention discloses an antenna dismounting device capable of avoiding the deformation of a waveguide cavity. The antenna dismounting device comprises a bottom plate (1), an antenna placing frame (2) and a force application part; and the force application part comprises a support (3), a rod (4), a pressing head (5), a force application nut (6) and a cushion block (7). A fuse system is placed into the antenna placing frame (2), and the orientation of the fuse system is adjusted so as to enable a to-be-detached antenna to be aligned with an axial sinking groove of the antenna placing frame (2); and the force application nut (6) is rotated clockwise to enable the pressing head (5) to press down, when the pressing head (5) is in contact with the antenna, the pressing head (5) is manually aligned with the center of the antenna and then is made to press down continuously until the middle rear part of the antenna is separated from a framework of the fuse system, and the middle front part of the antenna is separated from the framework of the fuse system. According to the antenna dismounting device, the problem of antenna failure caused by the deformation of the waveguide cavity of the antenna due to knocking and single-point force applying to dismount waveguide slotted array antennas is solved; and the device is simple to operate, stable in result, low in cost and wide in application.
Description
technical field [0001] The invention relates to an antenna dismantling device, in particular to an antenna dismantling device which avoids deformation of a waveguide cavity. Background technique [0002] The waveguide slot array antenna is a slot array antenna processed on the waveguide wall. Its parameter characteristics are very satisfied with the requirements of the fuze system, and because of its convenient installation and flexible feeding mode, it is widely used in airborne radar and shipborne radar antenna. and other fields. [0003] In the fuze system, the waveguide slot array antenna is usually assembled by bonding according to the frame structure of the fuze system. For example, in the fuze system with a conical frame structure, a plurality of strip-shaped waveguide slot array antennas are evenly distributed in the slots around the frame, and are fixed with silicone rubber. In the early stage of the development of the fuze system, due to experiments and other wor...
