[0002] The aircraft gun system is loaded on the aircraft and has the particularity of use. It must not only be lightweight, but also meet certain requirements for the amount of ammunition stored. The ammunition feeding device is mainly composed of ammunition box components, guide components, ammunition feeding joint components, ammunition belt components, etc. The ammunition feeding device adopts a linear chainless box feeding system that can orderly recover shells, and has the functions of feeding, storing and recovering shells.

[0003] The ammunition feeding device is connected to the automatic machine of the aircraft gun through the ammunition feeding joint. The ammunition feeding joint ensures that the shells on the ammunition belt smoothly enter the aircraft gun feeding body and the shells (or shells) after firing smoothly enter the ammunition belt, and at the same time transmits the power of the automatic machine to the ammunition feeding device through gears. However, when the ammunition feeding joint of the current ammunition feeding device is connected to the feeding body on the aircraft gun automatic machine, there are often problems such as too complicated installation operation, long time consumption, and insufficient installation adaptability.

[0004] In view of this, based on the existing chainless feeding, ammunition storage and shell recovery methods, it is necessary to design a device that can not only meet the required feeding power transmission and weight requirements, but also can quickly combine and separate to ensure that the shells on the ammunition belt smoothly enter the feeding body and the shells (or bullets) after shooting smoothly enter the ammunition belt.

[0005] To this end, the present invention designs a rocker operating mechanism in the ammunition feed joint, which can realize the rapid separation and combination of the ammunition feed device and the aircraft gun automatic machine and the power transmission function in the ammunition feed device through the separation and combination of the ammunition feed joint and the ammunition feed body.

[0032] At the same time, the present invention provides a method for using the rocker operating mechanism for the ammunition feed joint, which is special in that it includes the following steps:

[0034] 2) Switch the use status of the rocker control mechanism according to the working conditions, as follows:

[0035] A. Locking state of the ammunition feed connector and the gun feed body

[0036] The rocker is rotated by a tool to make the slider slide upward relative to the slide cover; driven by the slider, the spline lever rotates relative to the feed joint frame body, and its upper end drives the feed joint spline shaft to retract, and the latch tongue slides horizontally outward along the feed joint frame body under the guidance of the curved guide groove, so as to realize the combination of the feed joint and the aircraft gun feed body; then, the matching relationship between the latch locking assembly and the switching through hole is changed, so that the latch locking assembly extends out of the slider body and is inserted into the central hole axis of the feed joint frame body, so as to control the locking of the feed joint and the aircraft gun feed body after being combined;

[0037] B. Disengagement between the ammunition feed connector and the cannon feed body

[0038] The matching relationship between the latch locking assembly and the switching through hole is changed to retract the latch locking assembly into the slider body; the rocker is rotated in the opposite direction using a tool to slide the slider downward relative to the slide cover; driven by the slider, the spline lever rotates relative to the feed joint frame body, and its upper end drives the spline shaft to extend, and the latch tongue slides horizontally inwardly and retracts along the feed joint frame body under the guidance of the curved guide groove, thereby realizing the release of the feed joint from the aircraft gun feed body.

[0039] Changing the matching relationship between the latch locking assembly and the switching through hole mainly refers to the position of the handle in the switching through hole.

[0040] Furthermore, the specific steps of step 1) are:

[0041] 1.1) Install the locking shaft of the latch locking assembly into the slider from the inner threaded hole end of the three-step step through hole, so that the threaded hole on the middle column section of the locking shaft is aligned with the vertical hole of the slider switching through hole; install the spring into the three-step step through hole, located between the step shaft of the locking shaft and the three-step step through hole of the slider;

[0042] 1.2) Screw the screw sleeve from the inner threaded hole end of the three-step step through hole into the slider and spot rivet it. The inner hole of the screw sleeve and the locking shaft are matched with each other. After that, when the end of the locking shaft exposed from the three-step step through hole of the slider is flush with the first sliding surface of the slider, install the handle into the threaded hole of the locking shaft and spot rivet it. At this time, the latch locking assembly is in a released state, ensuring that the locking shaft can rotate flexibly in the slider and slide flexibly in the screw sleeve;

[0043] 1.3) Install the rocker's boss into the connecting hole of the first-stage plate structure of the slider;

[0044] 1.4) Insert the two protrusions of the two latches into the two curved guide grooves of the slider respectively;

[0045] 1.5) Install the two symmetrical first lug surfaces at the lower end of the spline lever into the two clamping holes of the limit groove of the slider respectively;

[0046] 1.6) Connect the first mounting hole of the rocker in the above mounting body (i.e. the mounting body obtained in step 1.5) to the convex shaft on the feed joint frame body to ensure flexible rotation, and the upper and lower sliding surfaces of the latch are adapted to the guide rail surface of the mounting position of the feed joint frame body to ensure flexible sliding;

[0047] 1.7) Match the two guide groove surfaces of the slide cover with the two first sliding surfaces of the slider, and connect the fastening holes of the slide cover connecting plate with the mounting holes on the feed joint frame body through fasteners to complete the assembly of the rocker operating mechanism. At this time, the upper end of the spline lever is inserted into the spline shaft slot of the feed joint, and the locking shaft of the latch locking assembly does not extend out of the three-step step through hole of the slider.

[0048] Principle of the present invention:

[0049] The rocker is rotated by a tool, and the rocker rotates with the first mounting hole as a fixed fulcrum, driving the slider to move up and down in the sliding cover, thereby driving the latch tongue to slide and retract in the guide groove of the feed joint frame body, and at the same time, the spline lever is driven to rotate with the pin shaft as a fulcrum through the limit groove of the slider and the first lug surface of the spline lever. The rotation of the spline lever further controls the axial extension and retraction of the spline shaft through the second lug surface, and the locking of the feed joint and the aircraft gun feed body after being combined is controlled by the pin-type locking assembly, thereby achieving the control of the rapid separation and combination of the feed joint and the aircraft gun feed body.

[0050] Turn the rocker counterclockwise, the tongue will retract, the spline lever will rotate, and the handle will be located at the release surface of the slider. At this time, the operating rocker mechanism is in the released state; rotate the handle 90° around the axis of the locking shaft and push it to the locking surface, turn the rocker clockwise, the tongue will extend, and the spline lever will rotate. At this time, the operating rocker mechanism is in the locked state.

[0051] The advantages of the present invention are:

[0052] 1. The rocker operating mechanism for the ammunition feed joint of the present invention adopts a rocker-slider-tab-spline lever in conjunction with a telescopic structure of the spline shaft of the ammunition feed joint. When the rocker is in place during operation, the rocker-slider-tab-spline lever and the telescopic structure of the spline shaft will not cause malfunction when there is no axial external force, thereby realizing the rapid separation of the ammunition feed device and the aircraft gun automatic machine, and the safety protection effect of the combined functional operation.

[0053] 2. The rocker operating mechanism for the ammunition feed joint of the present invention is easy to operate. Only one person needs to turn the rocker with one hand to install the ammunition feed joint and then realize the rapid separation and combination of the ammunition feed device and the aircraft gun automatic machine, which greatly reduces human resources and shortens the combat readiness time to a great extent.

[0054] 3. The rocker operating mechanism for the ammunition feed joint of the present invention converts a simple rotation into a translational motion in two directions (axial extension and contraction of the spline shaft and horizontal extension and contraction of the latch tongue), thereby ensuring the reliability of the connection. In addition, the reliable latch locking assembly provides a reliable guarantee for the ammunition feeding of the aircraft gun and the orderly recovery of the shells.

[0055] 4. The slide cover of the rocker operating mechanism for the ammunition feed joint of the present invention adopts a butterfly structure, and the upper and lower convex surfaces are respectively provided with through holes on the left and right symmetrical surfaces, which are fixedly connected to the ammunition feed joint frame, and the left and right symmetrical guide groove surfaces provide a track for the slide block to slide up and down, which is convenient for installing and removing the slide block and the tongue and other parts, solves the problem of difficulty in later maintenance and improves the efficiency of later maintenance and maintenance;

[0056] 5. The structure of the components in the rocker operating mechanism for the ammunition feed joint of the present invention is optimized. On the basis of meeting the space installation requirements and the required functions, the lightweight is ensured as much as possible, the material utilization rate is better guaranteed, and the economic benefits of the factory are improved.

[0091] 1.1) Install the locking shaft of the latch locking assembly into the slider from the inner threaded hole end of the three-step step through hole, so that the threaded hole on the middle column section of the locking shaft is aligned with the vertical hole of the slider switching through hole; install the spring into the three-step step through hole, located between the step shaft of the locking shaft and the three-step step through hole of the slider;

[0092] 1.2) Screw the screw sleeve from the internal thread end of the three-step step through hole into the slider and rivet it. The inner hole of the screw sleeve and the locking shaft are matched with each other. After that, when the end of the locking shaft exposed from the three-step step through hole of the slider is flush with the first sliding surface of the slider, install the handle into the threaded hole of the locking shaft and rivet it. At this time, the latch locking assembly is in a released state, ensuring that the locking shaft can rotate flexibly in the slider and slide flexibly in the screw sleeve;

[0093] 1.3) Install the rocker's boss into the connecting hole of the first-stage plate structure of the slider;

[0094] 1.4) Insert the two protrusions of the two latches into the two curved guide grooves of the slider respectively;

[0095] 1.5) Install the two symmetrical first lug surfaces at the lower end of the spline lever into the two clamping holes of the limit groove of the slider respectively;

[0096] 1.6) Connect the first mounting hole of the rocker in the mounting body to the convex shaft on the feed joint frame to ensure flexible rotation, and the upper and lower sliding surfaces of the tongue are adapted to the guide rail surface of the mounting position of the feed joint frame to ensure flexible sliding;

[0097] 1.7) Match the two guide groove surfaces of the slide cover with the two first sliding surfaces of the slider, and connect the fastening holes of the slide cover connecting plate with the mounting holes on the feed joint frame to complete the assembly of the rocker operating mechanism. At this time, the upper end of the spline lever is inserted into the spline shaft slot of the feed joint, and the locking shaft of the latch locking assembly does not extend out of the three-step step through hole of the slider and is in a released state.

[0098] 2) Switch the use status of the rocker control mechanism according to the working conditions, as follows:

[0099] A. The locking state of the ammunition feed connector and the cannon feed body, refer to Figure 4

[0100] The tool is used to rotate the rocker clockwise to make the slider slide upward relative to the slide cover; driven by the slider, the spline lever rotates relative to the feed joint frame body, and its upper end drives the feed joint spline shaft to retract, and the latch tongue is guided by the curved guide groove and slides horizontally outward along the feed joint frame body to achieve the combination of the feed joint and the aircraft gun feed body; then, the matching relationship between the latch locking assembly and the switching through hole is changed (here, it mainly refers to rotating the handle 90° around the axis of the locking shaft and pushing it to the locking surface. At this time, the spring is relaxed and has a pressing effect on the locking shaft), so that the latch locking assembly extends out of the slider body and is inserted into the center hole axis of the feed joint frame body, thereby controlling the locking of the feed joint and the aircraft gun feed body after being combined;

[0101] B. The state of the feed connector and the gun feed body being released, refer to Figure 3

[0102] The matching relationship between the latch locking assembly and the switching through hole is changed (here, mainly by placing the handle at the release surface, at which time the release surface has a limiting effect on the handle) to retract the latch locking assembly into the slider body; the rocker is rotated counterclockwise using a tool to slide the slider downward relative to the slide cover; driven by the slider, the spline lever rotates relative to the feed joint frame body, and its upper end drives the spline shaft to extend, and the latch tongue slides horizontally inwardly along the feed joint frame body under the guidance of the curved guide groove, thereby realizing the release of the feed joint and the aircraft gun feed body.

[0103] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
