Description

Technical Field

[0001] The present invention relates to the technical field related to barrel cleaning machines, and in particular to a portable barrel cleaning machine. Background Art

[0002] After the cannon is fired, the gun barrel is in a high temperature and high pressure environment, and the residues generated by the combustion of gunpowder will adhere to the inner wall of the barrel, forming carbon deposits. If the above residues are not cleaned in time, it will affect the normal movement of the projectile in the barrel, and the barrel will be worn, thereby reducing the shooting accuracy of the cannon; therefore, cleaning and maintenance of the inner barrel of the cannon is extremely important. The bore cleaning machine is mainly used to clean the barrel wall of cannons and other guns, remove attachments and rust on the inner wall of the barrel, and restore or maintain the performance of the cannon.

[0003] There are portable automatic bore cleaning machines in the prior art, and their power sources include pneumatic and electric. Electric bore cleaning machines need to be plugged in for use, and pneumatic bore cleaning machines can be connected to a pressure tank to use high-pressure gas as power for grinding and cleaning. When the bore cleaning brush rotates, the inner wall of the barrel is cleaned. However, after the bore cleaning brush is cleaned, it is necessary to replace the bore cleaning brush with a different material. For example, a layer of non-woven fabric is wrapped around the outside of the previous bore cleaning brush to clean the metal chips and other attachments that have fallen into the barrel before. It takes multiple wiping back and forth to clean up the metal chips and attachments that have fallen before, and the cleaning efficiency is low, so a portable bore cleaning machine needs to be designed. Summary of the invention

[0006] The expansion mechanism includes a plurality of fan-shaped slides evenly distributed along the circumferential direction of the mounting plate and slidably mounted on the mounting plate along the radial direction corresponding to the mounting plate, and a transmission plate used to drive the plurality of fan-shaped slides to gather or disperse when the rotating shaft rotates. An arc-shaped rubber strip that can fit the inner wall of the barrel is mounted on the outer edge of the fan-shaped slide, and the two ends of the arc-shaped rubber strip are respectively in sliding contact with two adjacent arc-shaped rubber strips in another group.

[0007] Preferably, the opposite sides of two adjacent fan-shaped skateboards are arranged in parallel, and a rubber block is arranged between the two adjacent fan-shaped skateboards, which is fitly assembled on the mounting plate and is in sliding contact with the sides of the two fan-shaped skateboards, and the side of the rubber block away from the mounting plate is in fit contact with the transmission plate.

[0008] Preferably, the transmission disk is fixedly connected coaxially with the rotating shaft, and the transmission disk is in sliding contact with the side of the fan-shaped slide away from the mounting disk. The side of the fan-shaped slide away from the mounting disk is recessed with an arc-shaped slide groove which is arranged eccentrically with the mounting disk, and the transmission disk is protruding with a guide column which is slidably inserted into the corresponding arc-shaped slide groove.

[0009] Preferably, at least one arc-shaped through groove coaxially arranged with the rotating shaft is penetrated on the transmission plate close to the equipment body, and the connecting member passes through the arc-shaped through groove and is fixedly connected with the mounting plate.

[0010] Preferably, a cover plate is fixedly mounted on the connecting member and is slidably fitted with the side of the transmission plate away from the mounting plate and can cover the arc-shaped through groove.

[0011] Preferably, a protrusion is protruding from the outer edge of the fan-shaped slide plate, which is slidably fitted with the fan-shaped slide plate in another group of expansion mechanisms.

[0012] Preferably, a side of the fan-shaped skateboard away from the mounting plate is recessed with a plurality of threaded holes arranged away from the axis of the mounting plate, each threaded hole is installed with a first mounting bolt passing through the arc-shaped rubber strip, and a plurality of first mounting bolts are sleeved with a pad that can interfere with the side of the arc-shaped rubber strip away from the mounting plate.

[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] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-5 As shown, a portable barrel scraping machine comprises: a cylindrical device body 1 and a scraping unit, the device body 1 comprises a rotating ring 2 and a barrel scraping brush 3 coaxially detachably assembled on the rotating ring 2, the scraping unit comprises a connecting sleeve 4 coaxially fixedly connected with the device body 1, a rotating shaft 5 coaxially passing through the connecting sleeve 4, a driving mechanism assembled inside the device body 1 for driving the rotating shaft 5 to rotate, a mounting plate 7 coaxially fixedly connected with the connecting sleeve 4 through a connecting member 6, and two groups of expansion mechanisms respectively arranged on two sides of the mounting plate 7, the rotating shaft 5 is axially connected with the mounting plate 7;

[0031] The expansion mechanism includes a plurality of fan-shaped slide plates 8 evenly distributed along the circumferential direction of the mounting plate 7 and slidably mounted on the mounting plate 7 along the radial direction corresponding to the mounting plate 7, and a transmission plate 9 used to drive the plurality of fan-shaped slide plates 8 to gather or disperse when the rotating shaft 5 rotates. An arc-shaped rubber strip 10 that can fit the inner wall of the barrel is mounted on the outer edge of the fan-shaped slide plate 8, and the two ends of the arc-shaped rubber strip 10 are respectively in sliding contact with two adjacent arc-shaped rubber strips 10 in another group.

[0032] In the above technical scheme, when the equipment body 1 moves toward the depth of the barrel, the rotating ring 2 will drive the barrel brush 3 to rotate and grind the inner wall of the barrel, and the driving mechanism will drive the rotating shaft 5 to rotate, so that the several fan-shaped slides 8 are gathered together, so that the arc-shaped rubber strips 10 on the several fan-shaped slides 8 do not contact the inner wall of the barrel. Therefore, the scraping unit can intercept the flying dust, metal chips, etc. when the barrel brush 3 is grinding to prevent them from splashing; when the equipment body 1 moves from the depth of the barrel to the muzzle, the driving mechanism drives the rotating shaft 5 to rotate in the opposite direction, driving the several fan-shaped slides 8 to disperse, and the arc-shaped rubber strips 10 will contact the inner wall of the barrel. Because there will be a gap between two adjacent arc-shaped rubber strips 10 in a group of expansion mechanisms, two groups of expansion mechanisms are required to be set. The arc-shaped rubber strips 10 in the two groups of expansion mechanisms fill the gap with each other, so that the scraping unit can scrape the dust and metal chips ground in the barrel toward the muzzle, which is convenient for cleaning and improves the cleaning efficiency.

[0033] In a preferred embodiment of the invention, the opposite sides of two adjacent fan-shaped skateboards 8 are arranged in parallel, and a rubber block 11 is provided between the two adjacent fan-shaped skateboards 8, which is fitly assembled on the mounting plate 7 and is in sliding contact with the side edges of the two fan-shaped skateboards 8, and the side of the rubber block 11 away from the mounting plate 7 is in fit contact with the transmission plate 9.

[0034] In the above technical solution, the rubber block 11 can intercept metal chips entering between two adjacent fan-shaped skateboards 8. The rubber block 11 has a certain elasticity and deformation ability due to the characteristics of its own material. Therefore, when the fan-shaped skateboard 8 slides, the distance between the two adjacent fan-shaped skateboards 8 will change, and the rubber block 11 can rely on its own material characteristics to always contact the side of the fan-shaped skateboard 8. When several fan-shaped skateboards 8 gather together, the distance between the two adjacent fan-shaped skateboards 8 is reduced. When the fan-shaped skateboards 8 are dispersed, the distance between the two adjacent fan-shaped skateboards 8 is increased.

[0035] In a preferred embodiment of the invention, the transmission disk 9 is fixedly connected coaxially with the rotating shaft 5, and the transmission disk 9 is in sliding contact with the side of the fan-shaped slide plate 8 away from the mounting disk 7. The side of the fan-shaped slide plate 8 away from the mounting disk 7 is recessed with an arc-shaped slide groove 12 which is arranged eccentrically with the mounting disk 7, and the transmission disk 9 is protruding with a guide column 13 which is slidably inserted into the corresponding arc-shaped slide groove 12.

[0036] In the above technical solution, when the rotating shaft 5 drives the transmission shaft to rotate, it drives the guide column 13 to slide in the corresponding arc-shaped groove 12. Because the arc-shaped groove 12 and the mounting plate 7 are arranged in an inclined state off-axis, when the guide column 13 slides in the arc-shaped groove 12, it can drive the fan-shaped slide plate 8 to slide on the mounting plate 7.

[0037] When the guide column 13 slides in the arc-shaped slide groove 12 close to the axial end of the arc-shaped slide groove 12 close to the installation shaft, it will drive the fan-shaped slide plate 8 to slide away from the axis of the installation shaft. When the guide column 13 slides in the arc-shaped slide groove 12 away from the axial end of the arc-shaped slide groove 12 away from the installation shaft, it will drive the fan-shaped slide plate 8 to slide close to the axis of the installation shaft.

[0038] In a preferred embodiment of the invention, at least one arcuate through slot 14 coaxial with the rotating shaft 5 is provided on the transmission disk 9 close to the device body 1 , and the connecting member 6 passes through the arcuate through slot 14 and is fixedly connected to the mounting disk 7 .

[0039] In a preferred embodiment of the invention, a cover plate 15 is fixedly mounted on the connecting member 6 and slides in contact with the side of the transmission plate 9 away from the mounting plate 7 and can cover the arc-shaped through groove 14 .

[0040] In the above technical solution, when the rotating shaft 5 drives the transmission disk 9 to rotate, the cover plate 15 will slide against the transmission disk 9 to prevent metal chips from entering between the transmission disk 9 and the mounting disk 7 through the arc-shaped through groove 14.

[0041] In a preferred embodiment of the invention, a protrusion 16 is protruding from the outer edge of the fan-shaped slide plate 8 for slidingly fitting with the fan-shaped slide plate 8 in another set of expansion mechanisms.

[0042] In the above technical solution, the protrusion 16 can increase the tightness of the two groups of expansion mechanisms and can scrape off more metal chips.

[0043] In a preferred embodiment of the invention, a side of the fan-shaped slide plate 8 away from the mounting plate 7 is recessed with a plurality of threaded holes arranged away from the axis of the mounting plate 7, each threaded hole is installed with a first mounting bolt 17 passing through the arc-shaped rubber strip 10, and a plurality of first mounting bolts 17 are sleeved with a pad 18 that can contact the side of the arc-shaped rubber strip 10 away from the mounting plate 7.

[0044] In the above technical solution, when the arc-shaped rubber strip 10 needs to be replaced, the old arc-shaped rubber strip 10 can be removed by loosening the first mounting bolt 17, and then the new arc-shaped rubber strip 10 can be assembled on the fan-shaped slide plate 8 through the first mounting bolt 17, so that the replacement is simple and convenient.

[0045] In a preferred embodiment of the invention, the bore wiping brush 3 comprises a pair of semi-annular bore wiping members, and the bore wiping members are assembled on the swivel 2 via a plurality of second mounting bolts.

[0046] In the above technical solution, because the scraping unit will hinder the installation of the bore wiping brush 3 , the bore wiping brush 3 is divided into two halves to facilitate the replacement of the bore wiping brush 3 .

[0047] In a preferred embodiment of the invention, the driving mechanism includes a force arm 19 fixedly connected to the rotating shaft 5 and with its length direction perpendicular to the axial direction of the rotating shaft 5, and an electric push rod 20 assembled inside the equipment body 1 through a hinge seat and with its output end hinged to the end of the force arm 19 away from the rotating shaft 5.

[0048] In the above technical solution, the electric push rod 20 drives the rotating shaft 5 to rotate through the force arm 19, thereby driving the two transmission disks 9 to rotate, and the two transmission disks 9 will drive the fan-shaped slide plate 8 to slide on the mounting disk 7.

[0049] In a preferred embodiment of the invention, a plurality of guide ridges 21 corresponding to the corresponding fan-shaped slide plates 8 are provided on both sides of the mounting plate 7, and a guide groove 22 cooperating with the guide ridge is provided on the fan-shaped slide plate 8.

[0050] In the above technical solution, when the transmission plate 9 rotates, the guide column 13 slides in the arc-shaped slide groove 12 , thereby driving the fan-shaped slide plate 8 to slide on the guide ridge 21 .

[0051] 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.

[0052] 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.

[0053] 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.
