Description

Technical Field

[0001] The present invention relates to the technical field of artillery maintenance, and in particular to a full-automatic gun bore cleaning system. Background Art

[0002] During the shooting process, the copper or nylon belt used in the projectile will have mechanical friction with the inner bore of the gun, causing some copper substances to remain on the surface of the inner bore of the barrel. Through the heat melting effect of high-temperature and high-pressure gas, some physical and chemical reactions will occur, forming "copper hanging" and "plastic hanging" phenomena, which are difficult to remove. Copper or plastic hanging will produce a micro-battery effect with the barrel matrix material, causing electrochemical reactions, causing rust in the barrel bore. In mild cases, it will produce a combination of point and mesh rust, which will not affect the gun shooting after wiping and maintenance. In severe cases, serious large-area rust pits will be produced, making the barrel scrapped. Therefore, the equipment maintenance specifications clearly state that the gun must be wiped and maintained after shooting.

[0003] To remove copper and residues from the barrel, troops currently usually use manual wiping methods. The tools used are usually gun wiping rods and gun brushes, which are used in conjunction with copper removers. The process is completed in the order of copper removal, punching, drying, and sealing. It usually takes 5 people about 2 hours to wipe a gun after shooting. The work is intensive and inefficient, which seriously affects the recovery of the equipment's technical performance.

DETAILED DESCRIPTION

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0018] like Figure 1 As shown, this embodiment is a fully automatic gun bore cleaning system, including a driving mechanism 1 and a cleaning mechanism 2. The driving mechanism 1 includes a housing 11, which is cylindrical in shape. The housing 11 is equipped with a driving motor 12, and the driving motor 12 is connected to a driving wheel 13 in a transmission manner; the side wall of the rear end of the housing 11 is provided with a driving wheel groove 14, and the driving wheel 13 is arranged in the driving wheel groove 14. The housing 11 is connected to the cleaning mechanism 2, and the cleaning mechanism 2 includes a cleaning motor 21, and the cleaning motor 21 is connected to a cylindrical brush 22. The cleaning mechanism 2 also includes a spray head 23, which is installed at the front end of the housing 11, and the spray head 23 is connected to a spray pipe 24, and the spray pipe 24 is connected to an external spray pump 25. The driving motor 12 and the cleaning motor 21 are both forward and reverse pneumatic motors, and the driving motor 12 and the cleaning motor 21 are connected to an external air supply mechanism 26.

[0019] like Figure 1-3 As shown, the drive motor 12 is connected to a worm 15, the worm 15 is connected to a worm wheel 16, the worm wheel 16 is connected to a drive wheel shaft 17, and the drive wheel shaft 17 is connected to a drive wheel 13. The center plane of the drive wheel groove 14 deviates from the axis of the housing 11, and the radius of one side of the drive wheel 13 is greater than the radius of the other side, so that the cross section of the drive wheel 13 along the axis is a trapezoid, and the worm wheel 16 is located on the side of the drive wheel 13 with a large radius.

[0020] like Figure 1 As shown, a side wall at the front end of the housing 11 is provided with a driven wheel groove 18 , a driven wheel shaft is rotatably connected to the driven wheel groove, and a driven wheel shaft is axially connected to a driven wheel 19 .

[0021] As shown Figure 4 in FIG. 1, the housing 11 includes a barrel body 111, a front cover 112 is fixedly connected to the front end of the barrel body 111, and a rear cover 113 is fixedly connected to the rear end of the barrel body 111; the barrel body 111 is formed by rolling a steel plate. A rectangular hole is provided in the barrel body 111 before rolling, and then a driving wheel groove 14 and a driven wheel groove 18 in the shape of a chute member are welded or riveted at the position of the rectangular hole.

[0022] As shown Figure 5-7 in FIG. 2, the housing 11 is connected to a cleaning mechanism 2. The cleaning mechanism 2 includes a rotating mechanism. The rotating mechanism includes a cleaning motor 21. The cleaning motor 21 includes an outer shaft 211. The outer shaft 211 penetrates through the cleaning motor 21 from front to back. An inner shaft 212 is slidably connected to the axis of the outer shaft 211. The inner shaft 212 penetrates through the outer shaft 211 from front to back. A first convex rib 2121 parallel to the axis of the outer shaft 211 is provided at the front end of the inner shaft 212. A first groove 2111 slidably connected to the first convex rib 2121 is provided on the inner wall of the outer shaft 211. A cylindrical brush 22 is connected to the front end of the inner shaft 212.

[0023] The rotating mechanism is connected to a reciprocating telescoping mechanism. The reciprocating telescoping mechanism includes a cleaning motor 21 and an outer shaft 211. A reciprocating cam groove 2112 is provided on the outer side of the tail of the outer shaft 211. A slider assembly 27 is slidably connected to the tail of the outer shaft 211.

[0024] As shown Figure 8-9 in FIG. 3, the slider assembly 27 includes a cylindrical slider 271. A second convex rib 2711 parallel to the axis of the outer shaft 211 is provided on the outer wall of the slider 271; the slider 271 is provided with a threaded hole, and an externally threaded cylindrical pin 272 is threadedly connected to the threaded hole. A limit post 2721 is provided at the end of the externally threaded cylindrical pin 272.

[0025] The limit post 2721 is slidably connected to the reciprocating cam groove 2112; the slider assembly 27 is slidably connected to a bracket 114. The bracket 114 includes a ring 1141. A second groove 1142 slidably connected to the second convex rib 2711 is provided on the inner side of the ring 1141. The ring 1141 is connected to a support rod 1143 connected to the housing 11.

[0026] A connecting frame 273 is connected to the tail of the slider assembly 27. The connecting frame 273 includes extending sections 2731 symmetrically arranged along the axis of the outer shaft 211. A connecting section 2732 parallel to the axis of the outer shaft 211 is connected to the extending sections 2731. A converging section 2733 is connected to the connecting section 2732. A collar 2734 is connected to the converging section 2733. The collar 2734 is sleeved on the tail end of the inner shaft 212.

[0028] During operation, the housing 11 together with the brush 22 is placed into the gun barrel, and the driving motor 12 drives the driving wheel 13 to push the housing 11 and the brush 22 to move in the gun barrel.

[0029] The cleaning motor 21 drives the outer shaft 211 to rotate. Since the groove two 1142 of the ring 1141 restricts the rotation of the rib two 2711 of the slider 271, the reciprocating cam groove 2112 on the outer shaft 211 will push the limit post 2721 of the slider assembly 27 to move back and forth. The slider assembly 27 drives the inner shaft 212 to move back and forth through the connecting frame 273, so that the cylindrical brush 22 brushes back and forth along the inner wall of the gun barrel.

[0030] At the same time, since the groove one 2111 of the outer shaft 211 restricts the rotation of the rib one 2121 of the inner shaft 212, the inner shaft 212 will rotate together with the outer shaft 211. Therefore, when the brush 22 moves linearly back and forth, the brush 22 is also rotating.

[0031] The external spray pump 25 and the air supply mechanism 26 are controlled by the console.

[0032] The technical features not described in the present invention can be realized by or adopted from the prior art, and will not be elaborated here.
