Description

Technical Field

[0001] This invention relates to the field of gun barrel cleaning technology, specifically a reciprocating cleaning device suitable for a shallow rifling gun barrel cleaning robot. Background Technology

[0002] Gun barrels are common components of modern military weapons. Gun barrel steel is usually rolled and welded through special heat treatment and forging processes to form gun barrels. Gun barrels are subjected to extremely high instantaneous pressure and temperature when the cannon is fired, so they need to be maintained frequently, including regular cleaning of the inner wall of the gun barrel.

[0003] Currently, when cleaning the gun barrel, it is usually cleaned in one direction only. This cleaning is not thorough and cannot completely clean the inner wall of the gun barrel. The cleaning speed is slow and requires a long time and a lot of manpower to complete, resulting in low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a reciprocating cleaning device suitable for a shallow rifling gun barrel cleaning robot, so as to solve the problems in the above-mentioned background technology that the cleaning is not thorough, cannot completely clean the inner wall of the gun barrel, the cleaning speed is slow, and requires a long time and a lot of manpower to complete, resulting in low efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reciprocating cleaning device suitable for a shallow rifling gun barrel cleaning robot, comprising:

[0006] Host;

[0008] The telescopic rod is adapted to be inserted into the top side of the main unit;

[0009] A cleaning brush is fixedly installed on one side of the bottom end of the telescopic rod;

[0010] A fixed base is fixedly installed at the top of the upright frame;

[0011] The frame is fixedly installed on both the left and right sides of the top of the fixed base;

[0012] The gun barrel is inserted into the inner cavity of the frame;

[0013] A limiting rotation mechanism is provided at the top of the frame;

[0014] A reciprocating drive mechanism is located inside the main unit.

[0015] Preferably, in order to limit the position of the gun barrel, the limiting and fixing mechanism includes: a hydraulic cylinder, which is fixedly disposed at the top of the frame; a pressure block, the bottom end of the hydraulic cylinder extending into the inner side of the frame and fixedly disposed thereon; and rollers, the bottom end of the pressure block having a groove, the inner cavity of the groove having a plurality of rollers fixedly disposed thereon, and some of the rollers being in contact with the top of the outer wall of the gun barrel.

[0016] Preferably, the inner front and rear ends of the frame are provided with sliding grooves in the vertical direction, and a slider is inserted into the inner cavity of the sliding groove, and the slider is fixedly connected to the outer side of the pressure block.

[0017] Preferably, the limiting and fixing mechanism further includes: a first reduction motor, fixedly disposed on one side of the upright; a rotating shaft, the output end of the first reduction motor extending into the inner cavity of the upright and locked with the rotating shaft by a coupling; and rotating wheels, with rotating wheels keyed to both the left and right sides of the outer wall of the rotating shaft, and the outer wall of the rotating wheel extending out of the inner side of the frame and contacting the bottom end of the outer wall of the gun barrel.

[0018] Preferably, the bottom end of the pressure block is an inwardly concave arc shape.

[0019] Preferably, the outer wall of the wheel is provided with friction texture.

[0020] Preferably, in order to drive the cleaning brush to reciprocate, the reciprocating drive mechanism includes: a second reduction motor, fixedly disposed on the rear side of the main unit; a turntable, the output end of the second reduction motor extending into the inner cavity of the main unit and fixedly disposed thereon; a swing column, rotatably disposed at the bottom rear side of the inner cavity of the main unit; a swing rod, adapted to be inserted into the top end of the swing column, and the top end of the swing rod being rotatably connected to the bottom side of the telescopic rod via a pin; and a push column, the front side of the swing column having a strip-shaped hole, the front side of the turntable being fixedly disposed thereon, and the push column being inserted into the inner cavity of the strip-shaped hole.

[0021] Preferably, the second reduction motor is started so that the second reduction motor drives the turntable to rotate clockwise around its own axis, thereby causing the push column to rotate clockwise in a circular motion. This causes the push column to push the inner wall of the strip hole, causing the swing column to swing back and forth around the connection point with the inner cavity of the main unit. Then, under the extension and retraction of the swing rod, the telescopic rod is driven by the limiting groove and the limiting block to drive the cleaning brush to move back and forth, so that the cleaning brush moves into the barrel and reciprocates to clean its inner wall.

[0023] The present invention proposes a reciprocating cleaning device suitable for cleaning robots of shallow rifling gun barrels, the advantages of which are:

[0024] 1. After the barrel is fixed, the present invention can drive the cleaning brush to extend and retract left and right by means of a reciprocating drive mechanism, thereby enabling reciprocating cleaning of the inside of the barrel. Compared with the unidirectional cleaning method, the cleaning work can be completed faster and more efficiently.

[0025] 2. By setting a limiting rotation mechanism, the present invention can limit the barrel and rotate it, so that the cleaning brush can thoroughly clean the inner wall of the barrel, ensuring a more thorough cleaning effect, realizing automated cleaning operation, reducing the need for manual operation, reducing human resource costs, and improving work efficiency.

The reciprocating drive mechanism 9 is installed in the inner cavity of the main unit 1.

[0035] As a preferred embodiment, the limiting and fixing mechanism 8 further includes: a hydraulic cylinder 81, a pressure block 82, a roller 83, a groove 84, a slide 85, a slider 86, a first reduction motor 87, a rotating shaft 88, and a rotating wheel 89.

[0036] In order to control the smooth lifting and lowering of the pressure block 82, the hydraulic cylinder 81 is fixedly installed at the top of the frame 6. The bottom end of the hydraulic cylinder 81 extends into the inner side of the frame 6 and is fixedly installed with the pressure block 82. The bottom end of the pressure block 82 is provided with a groove 84. Several rollers 83 are fixedly installed in the inner cavity of the groove 84, and some of the rollers 83 are in contact with the top of the outer wall of the gun barrel 7. The rollers 83 can limit the movement of the gun barrel 7, and the rolling of the rollers 83 can facilitate the rotation of the gun barrel 7.

[0037] In order to limit the pressure block 82, the inner front and rear ends of the frame 6 are provided with sliding grooves 85 in the vertical direction. The inner cavity of the sliding groove 85 is connected to a slider 86, and the slider 86 is fixedly connected to the outer side of the pressure block 82.

[0038] In order to drive the rotating wheel 89 to rotate the gun barrel 7, the first reduction motor 87 is fixedly installed on one side of the support frame 2. The output end of the first reduction motor 87 extends into the inner cavity of the support frame 2 and is locked with the rotating shaft 88 through a coupling. The rotating wheel 89 is keyed to both the left and right sides of the outer wall of the rotating shaft 88, and the outer wall of the rotating wheel 89 extends out of the inner side of the frame 6 and contacts the bottom end of the outer wall of the gun barrel 7.

[0039] As a preferred option, the bottom of the pressure block 82 is an inwardly concave arc shape to facilitate the positioning and fixing of the gun barrel 7.

[0040] To ensure that the barrel 7 can be turned, the outer wall of the rotary wheel 89 is provided with friction grooves.

[0041] As a preferred embodiment, the reciprocating drive mechanism 9 further includes: a second reduction motor 91, a turntable 92, a swing column 93, a swing rod 94, a push column 95, a strip hole 96, a limiting groove 97, and a limiting block 98;

[0042] In order to drive the turntable 92 to rotate, the second gear motor 91 is fixedly installed on the rear side of the main unit 1. The output end of the second gear motor 91 extends into the inner cavity of the main unit 1 and is fixedly installed with the turntable 92.

[0043] In order to drive the pendulum 93 to swing back and forth, the pendulum 93 is rotatably set at the bottom rear side of the inner cavity of the main unit 1. The top end of the pendulum 94 is adapted to be inserted into the pendulum 93, and the top end of the pendulum 94 is rotatably connected to the bottom side of the telescopic rod 3 through a pin.

[0044] In order to control the telescopic rod 3 to move stably, a limiting groove 97 is opened at the top of the inner cavity of the main unit 1 along the left and right direction, and a limiting block 98 is inserted into the inner cavity of the limiting groove 97. The limiting block 98 is fixedly connected to one side of the top of the telescopic rod 3.

[0045] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0046] Step 1: First, fix the gun barrel 7 inside the frame 6, start the hydraulic cylinder 81, so that the hydraulic cylinder 81 pushes the pressure block 82 to move downward under the restriction of the slide groove 85 and the slider 86, so that the pressure block 82 moves downward smoothly and the roller 83 presses the gun barrel 7 into the frame 6, and the roller 83 and the rotating wheel 89 limit the gun barrel 7.

[0047] Step 2: Start the second reduction motor 91 so that the second reduction motor 91 drives the turntable 92 to rotate clockwise around its own axis, thereby driving the push column 95 to rotate clockwise in a circular motion. This causes the push column 95 to push the inner wall of the strip hole 96, causing the swing column 93 to swing back and forth around the connection with the inner cavity of the main unit 1. Then, under the extension and retraction of the swing rod 94, the telescopic rod 3 drives the cleaning brush 4 to move back and forth in the left and right under the restriction of the limiting groove 97 and the limiting block 98, so that the cleaning brush 4 moves into the barrel 7 and performs reciprocating cleaning on its inner wall.

[0048] Step 3: Start the first reduction motor 87. The first motor 87 can drive the rotating shaft 88 to rotate clockwise, so that the rotating shaft 88 drives the rotating wheel 89 to rotate clockwise, thereby enabling the rotating wheel 89 to rotate the cannon barrel 7 counterclockwise, so that the cleaning brush 4 can thoroughly clean the inner wall of the cannon barrel 7, making the cleaning more thorough and efficient.
