Description

Technical Field

[0001] The utility model relates to the technical field of airborne radar disassembly tools, in particular to a combined screwdriver head tool for disassembling waveguide screws. Background Art

[0002] The antenna array of the mechanical scanning radar is installed on the antenna base. In addition to the ordinary screws and other fasteners for fixing the antenna, the connection between the two is also connected by multiple waveguides. In order to reduce weight and volume and meet the requirements of the three-way scanning angle of the antenna and the safety gap between the antenna and the antenna cover, the structure of the antenna and the antenna base is designed to be very compact. The problem is that the waveguide connection screws between the two cannot be tightened / disassembled using common tools, which affects the mass production test of the radar and the maintenance of the radar on the user's aircraft.

[0003] The hexagon socket connection screws of the waveguide port are generally designed to be non-loose, and if the disassembly and assembly are in accordance with the specification, there is no possibility of the screws falling off; however, if a ball-head hexagon wrench is spliced ​​with an ordinary hexagon socket screwdriver head, the ball-head hexagon wrench is easy to fall off during the disassembly and assembly of the screws, affecting the disassembly and assembly efficiency, and the fallen wrench is easy to fall into the cavity of the antenna base arm where the waveguide is connected, leaving a major safety hazard, and the simple splicing and length do not meet the installation requirements. In response to this hazard and the disassembly and assembly distance requirements, a magnetic ratchet screwdriver head is used to extend the operating distance, solving the problem of safe and fast disassembly and assembly of multi-channel waveguide port screws.
