Description

Technical Field

[0001] The present invention relates to the technical field of artillery bore cleaning machines, and in particular to a muzzle clamping mechanism of an artillery bore cleaning machine. Background Art

[0002] After the gun is fired, due to the effects of high temperature and high pressure, the residues generated by the combustion of the propellant will adhere to the inner bore of the barrel and form carbon deposits. The presence of the above residues affects the normal movement of the projectile in the bore and reduces the shooting accuracy of the gun. It will also accelerate the wear of the inner bore and damage the rifling during subsequent firing. In severe cases, it will cause the barrel to bulge or explode. At present, most guns use gun barrel cleaning machines to automatically wipe. When connected to the muzzle brake, it is necessary to design a special connection device for different muzzle brakes, which not only increases the number of parts and manufacturing costs, but also is not universal and difficult to maintain.

[0003] After searching: Chinese patent application number is "CN201420665858.5", which discloses a muzzle clamping mechanism of a gun bore cleaning machine, which is composed of a handle, a V-shaped iron, a connecting block, a screw, a shaft I, a sleeve, a handle nut, a shaft II, a column, a pad, a column nut, a screw A, a screw B, a washer A, a washer B, a pin and a precision roller chain. The V-shaped iron and the precision roller chain form a closed ring to achieve connection with the muzzle. The screw on the V-shaped iron is hingedly connected to the precision roller chain. After the chain is passed around the sleeve on the shaft I, it is passed around the muzzle brake from one side of the V-shaped iron, and the pin on the precision roller chain is installed in the U-shaped groove of the shaft II, and the precision roller chain is fixed on the other side of the V-shaped iron.

[0004] The inventor discovered the following problems in the prior art during the implementation of the present invention:

[0005] The existing clamping mechanism is assembled by threaded connection, which requires manual connection by staff, reducing the efficiency of assembly and disassembly. In addition, the clamping mechanism has fewer supporting points between the muzzles, which reduces the stability and reliability of the clamping mechanism.

[0006] Therefore, it is an urgent problem to be solved by the present invention to provide a muzzle clamping mechanism for a gun bore cleaning machine, which can drive all the clamping plates toward the muzzle until they rest against the muzzle through a linkage mechanism during use, thereby quickly clamping and fixing the muzzle, improving the disassembly and assembly efficiency, and increasing the clamping points on the muzzle to improve the stability and reliability of the clamping of the entire clamping mechanism. Summary of the invention

[0007] In view of the above technical problems, the purpose of the present invention is to overcome the problem that the prior art uses a threaded connection method for assembly, which requires manual connection by staff, reduces the efficiency of disassembly and assembly, and has fewer supporting points between the clamping mechanism and the muzzle, reducing the stability and reliability of the clamping mechanism. Thus, a muzzle clamping mechanism for a gun bore cleaning machine is provided, which can drive all the clamping plates toward the muzzle through a linkage mechanism during use until they rest against the muzzle, thereby quickly clamping and fixing the muzzle, improving the efficiency of disassembly and assembly, and by adding multiple clamping points to clamp the muzzle, thereby improving the stability and reliability of the clamping of the entire clamping mechanism.

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] like Figure 1-4 As shown, the present invention provides a muzzle clamping mechanism of a gun bore cleaning machine, the mechanism comprising a No. 1 clamping seat 1, a No. 2 clamping seat 2, a clamping plate 3 and a linkage mechanism 4;

[0030] The first clamping seat 1 and the second clamping seat 2 of the same structure are fixed together at intervals and coaxially. In the inner cavity of the ring-shaped first clamping seat 1, a plurality of clamping plates 3 movable in the radial direction are arranged at equal intervals along the circumferential direction through the linkage mechanism 4. The linkage mechanism 4 includes: a linkage tooth plate 401, a linkage tooth roller 402 and a linkage tooth ring 403; wherein,

[0031] The interior of the No. 1 clamping seat 1 is a hollow structure, and a linkage gear ring 403 is horizontally and rotatably provided at the bottom of the interior of the No. 1 clamping seat 1, and a linkage tooth plate 401 that can partially penetrate along the radial direction of the No. 1 clamping seat 1 is vertically fixed on each of the clamping plates 3 located above the linkage gear ring 403 and facing the inner wall of the No. 1 clamping seat 1, and a linkage gear roller 402 that is respectively meshed with the linkage tooth plate 401 and the linkage gear ring 403 is rotatably provided inside the No. 1 clamping seat 1 next to each of the linkage tooth plates 401, and the bottom end of the central rotating shaft of any one of the linkage gear rollers 402 is coaxially connected to the motor vertically fixed inside the No. 1 clamping seat 1 through a coupling.

[0032] In the above solution, at least four clamping plates 3 are provided, and in addition, the motor is a reduction motor.

[0033] When using, Figure 1-4 As shown, the muzzle is passed through the No. 1 clamping seat 1, and then the motor is started so that the motor drives the interlocking gear roller 402 coaxially connected thereto to rotate, and the interlocking gear roller 402 can drive the interlocking tooth plate 401 meshing therewith to drive the clamping plate 3 at its end toward the muzzle until the clamping plate 3 abuts against the muzzle. At the same time, the interlocking gear roller 402 can drive the interlocking gear ring 403 to rotate during the rotation, so as to drive all the remaining interlocking gear rollers 402 meshing therewith to rotate together through the interlocking gear ring 403, and all the remaining interlocking gear rollers 402 can respectively drive all the remaining interlocking tooth plates 401 to drive all the clamping plates 3 at their tops toward the muzzle until they abut against the muzzle.

[0034] Then extend the port of the muzzle brake into the No. 2 clamping seat 1 and align the port of the muzzle brake with the muzzle. After alignment, follow the above operation to quickly connect the muzzle brake and the muzzle together through the linkage mechanism 4 and clamp them in the entire clamping mechanism.

[0035] Therefore, the linkage mechanism 4 can drive all the clamping plates 3 toward the muzzle until they rest against the muzzle, thereby quickly clamping and fixing the muzzle, and the clamping of the muzzle by multiple clamping plates 3 can improve the stability and reliability of the clamping of the entire clamping mechanism.

[0036] In a preferred embodiment of the present invention, two guide rods 5 symmetrical about the linkage tooth plate 401 are fixedly arranged at intervals on each of the clamping plates 3 facing the inner wall of the No. 1 clamping seat 1, and the free end of each of the guide rods 5 can partially extend out of the interior of the No. 1 clamping seat 1.

[0037] In the above scheme, the inner wall of the No. 1 clamping seat 1 is provided with guide holes for all the guide rods 5 to pass through at equal intervals along its circumferential direction. Through the coordinated use of the guide holes on the No. 1 clamping seat 1 and the corresponding guide rods 5, it can be ensured that all the clamping plates 3 can move smoothly and reliably in a straight line along the radial direction of the No. 1 clamping seat 1.

[0038] In a preferred embodiment of the present invention, a spring 8 is sleeved on each of the guide rods 5 , and two ends of each of the springs 8 are respectively fixed on the No. 1 clamping seat 1 and the clamping plate 3 .

[0039] In the above scheme, the spring 8 plays a buffering role. When in use, each of the clamping plates 3 is in a stretched state during the process of moving toward the muzzle. Conversely, when each of the clamping plates 3 moves away from the muzzle and approaches the inner wall of the No. 1 clamping seat 1, the spring 8 recovers from the stretched state to its initial naturally stretched state.

[0040] In a preferred embodiment of the present invention, the linkage gear ring 403 is coaxially and rotatably disposed on the outer side wall inside the No. 1 clamping seat 1 through a bearing 7 .

[0041] In the above scheme, if Figure 2 and Figure 3 As shown, the linkage tooth plate 401 is located above the linkage tooth ring 403, and the inner wall of the linkage tooth ring 403 is evenly fixed along its circumferential direction with a circle of rack groups meshing with all the linkage tooth rollers 402, and the length of each linkage tooth roller 402 is greater than the sum of the thickness of the linkage tooth plate 403 and the height of the linkage tooth ring 403, so that the rack group on the surface of each linkage tooth roller 402 can be meshed with the linkage tooth plate 401 and the linkage tooth ring 403 at the same time, so that one of the linkage tooth rollers 402 can drive all the remaining linkage tooth rollers 402 meshing with it to rotate during the rotation process, so that all the linkage tooth rollers 402 can drive all the linkage tooth plates 401 meshing with them to drive all the clamping plates 403 fixed on their respective ends to move along the radial direction of the No. 1 clamping seat 1 or the No. 2 clamping seat 2 during the synchronous rotation.

[0042] In a preferred embodiment of the present invention, the mechanism further comprises a connecting member 6 which connects the No. 1 clamping seat 1 and the No. 2 clamping seat 2 together in a fixed manner at intervals; wherein,

[0043] The outer wall of the No. 1 clamping seat 1 is provided with a plurality of connecting pieces 6 parallel to its axial direction at equal intervals along its circumferential direction, and the free end of each of the connecting pieces 6 is fixed on the No. 2 clamping seat 2 .

[0044] In the above scheme, the first clamping seat 1 and the second clamping seat 2 are spaced apart and coaxially connected together by a plurality of connecting members 6 to improve the mechanical strength of the entire clamping mechanism.

[0045] In addition, since the No. 1 clamping seat 1 and the No. 2 clamping seat 2 are spaced and coaxially arranged, it is possible to observe through the gap between the two whether the connection ends of the muzzle and the muzzle brake are aligned.

[0046] In a preferred embodiment of the present invention, the side walls of the No. 1 clamping seat 1 and the No. 2 clamping seat 2 are both made of transparent material.

[0047] In the above scheme, since both are made of transparent materials, the moving positions of all the clamping plates 3 can be observed through the transparent side walls of the No. 1 clamping seat 1 and the No. 2 clamping seat 2 .

[0048] In summary, the muzzle clamping mechanism of the artillery bore cleaning machine provided by the present invention overcomes the problem of the prior art using a threaded connection method for assembly, which requires manual connection by staff and reduces the efficiency of disassembly and assembly, and the clamping mechanism has fewer support points between the muzzles, reducing the stability and reliability of the clamping mechanism.

[0049] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0051] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
