Description
Technical Field
[0001] This utility model relates to the field of aircraft airborne cannon calibration technology, and in particular to an installation structure for an aircraft cannon target calibration instrument. Background Technology
[0002] Aircraft-borne cannons require regular calibration; otherwise, their firing accuracy will be affected. Cannon calibration utilizes electronic target plates and computer technology, enabling computer-controlled calibration processes. The cannon's own calibration system consists of an electronic target plate, a target plate calibration exciter, a cannon calibration exciter, a target plate mounting bracket, and a portable computer. The electronic target plate is a precision electronic device, powered by 28V DC. Its external interfaces include a power interface, an RS-232 interface, two calibration exciter interfaces, and two calibration exciter interfaces. The exciter consists of a metal structure and a non-metallic probe.
[0003] Existing electronic target plates, target plate calibration exciters, cannon target calibration exciters, and fixed electronic target plates cannot be directly connected and installed on the aircraft using a single fastener. Multiple fasteners are required for installation. Furthermore, the electronic target plates are installed in a fixed position on the aircraft, and adjustments must be made by removing them from the fasteners, which is very inconvenient. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an installation structure for an aircraft cannon target calibration device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An installation structure for an aircraft cannon target calibration device includes a fuselage, an electronic target plate disposed on the lower part of the fuselage, a horizontal slide rail disposed at the bottom of the fuselage, a mounting bracket fixedly mounted on the side wall of the horizontal slide rail, a slider movably mounted in the horizontal slide rail, a left-right rotation mechanism disposed at the bottom of the slider, the left-right rotation mechanism including a threaded boss, an upper threaded right-hand rod, a handle, and a lower threaded left-hand rod, a pitch mechanism disposed on the back of the electronic target plate, the pitch mechanism including a target frame and a connecting frame, the electronic target plate being fixedly mounted on the connecting frame, and the connecting frame being... A rotating shaft screw is fixedly installed on the mounting bracket. A connecting groove is provided on the target bracket at the position corresponding to the rotating shaft screw. The rotating shaft screw can be movably inserted into the connecting groove. A fixing block is fixedly installed on the bottom of the fuselage. An aircraft cannon target calibration exciter is installed on the fixing block. The top of the aircraft cannon target calibration exciter is in contact with the electronic target plate. A fixing frame is provided between the electronic target plate and the fixing block. The fixing frame is fixedly installed on the fuselage. A target plate calibration exciter is installed on the fixing frame. The top of the target plate calibration exciter is also in contact with the electronic target plate.
[0006] As a further embodiment of this utility model, the threaded boss is fixedly mounted on the slider, and an upper threaded right-hand rod is threadedly connected to the lower part of the threaded boss. A handle is threadedly installed below the upper threaded right-hand rod, and a lower threaded left-hand rod is threadedly connected to the bottom of the handle.
[0007] As a further embodiment of this utility model, the side wall of the target frame is provided with a connecting groove, and a limiting pin is fixedly installed on the side wall of the connecting frame corresponding to the limiting groove. The limiting pin can be movably installed in the limiting groove.
[0008] As a further embodiment of this utility model, a lead screw is fixedly installed at the bottom of the left-hand threaded rod, and a fixing groove is provided on the target frame, so that the lead screw at the bottom of the left-hand threaded rod can be movably installed in the fixing groove.
[0009] As a further embodiment of this utility model, the mounting bracket has four elliptical holes.
[0010] As a further embodiment of this invention, the tops of the target plate calibration exciter and the gun calibration exciter are conical.
[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the four elliptical holes on the mounting bracket solve the problem of fixing two types of target calibration devices for an aircraft. Furthermore, the horizontal slide rail and slider ensure the forward and backward movement of the electronic target plate, the left and right rotation mechanism ensures the up and down movement of the electronic target plate, the lead screw and fixing groove ensure the left and right rotation of the electronic target plate, and the connecting bracket behind the electronic target plate rotates around a point to ensure the up and down rotation of the electronic target plate. By combining these five methods organically, a target calibration device is formed, which facilitates multi-directional adjustment of the electronic target plate and enables the target calibration device to complete the target calibration task well.
