Description

Technical Field

[0001] The present invention relates to the technical field of artillery maintenance devices, and in particular to a portable gun bore oiling device. Background Art

[0002] Artillery is an important combat weapon in modern warfare, used to fire shells to kill and destroy enemy manpower and fortifications. Rifled or smoothbore guns used in modern military use chemical energy to fire, so every time a gun is fired, there will be flames and smoke, and some gunpowder residue will remain in the barrel. Over time, a layer of black residue will remain in the barrel.

[0003] Due to the unclean cleaning of the gun bore, copper and carbon deposits are formed, which hinders the movement of the projectile in the gun bore and causes the gun bore to explode. Therefore, the gun bore of large artillery needs to be cleaned and maintained when it is unsealed or sealed, as well as after firing the shells. The cleaning of the gun bore includes the removal of foreign matter in the gun bore and the rust prevention of the gun bore. Foreign matter in the gun bore includes metals such as copper, zinc, lead, and aluminum that fall off from the projectile, oxidized residues of aluminum, and residues from the combustion of gunpowder in the barrel, such as soot and graphite attached to the inner wall of the gun bore, as well as foreign matter caused by rust in the gun bore. The above foreign matter can easily block and corrode the inner wall of the gun bore, aggravating the wear and corrosion of the inner wall of the gun bore. Especially during the artillery firing process, the residue (carbon deposits) attached to the inner wall of the barrel under high temperature and high pressure are tightly bonded to the barrel. In addition, since the length of the barrel is much larger than the diameter of the inner wall of the barrel, the residue will not only affect the shooting accuracy, but also reduce the life of the barrel. Therefore, cleaning the barrel is a very important task, and it is also one of the indispensable procedures for daily maintenance of artillery. The barrel needs to be cleaned and oiled for protection after use.

[0004] However, the actual oiling technology currently used is still manual oiling, where a cloth strip is tied to a long pole, dipped in grease and rubbed back and forth on the inner wall of the barrel. This type of barrel oiling is not only time-consuming and laborious, but also uneven, resulting in a huge waste of grease. In addition, for barrels with rifling, there is even a situation where the rifling roots cannot be oiled, thus losing the protective effect. Summary of the invention

[0005] The present invention aims to solve the deficiencies of the prior art and provides a portable gun bore oiling device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, the outer diameter of the baffle is smaller than the inner diameter of the barrel, which provides a certain support for the velvet wheel, ensuring that the grease on the surface of the velvet wheel can be fully applied to the bore, especially for a rifled bore, the velvet wheel can squeeze the grease to the root of the groove to achieve good protection.

[0011] Preferably, the outer diameter of the baffle is the same as the outer diameter of the baffle.

[0012] Preferably, an oil chamber is formed between the retaining ring and a pair of wiping wheels on both sides thereof and the working surface of the barrel. When applying grease, excess grease on the surface of the velvet wheel can enter the oil chamber. At the same time, under the action of centrifugal force, the grease in the oil chamber can reach the surface of the barrel, thereby achieving uniform oiling of the barrel.

[0013] Preferably, a mounting hole 1 is coaxially provided on the baffle, the transmission shaft passes through the mounting hole 1, and a limiting slot 1 connected to the mounting hole 1 is provided on the baffle, and the limiting slot 1 is adapted to the flat key.

By providing a baffle ring, a baffle plate and a baffle plate, an oil chamber is formed with the working gun barrel surface, which can also store grease and enter the velvet wheel through the opening on the baffle. When grease is applied, excess grease on the surface of the velvet wheel can enter the oil chamber. At the same time, under the action of centrifugal force, the grease in the oil chamber can reach the gun barrel surface, thereby achieving uniform oiling of the gun barrel and achieving the purpose of saving time, labor and grease. For a gun barrel with rifling, the velvet wheel can squeeze the grease to the root of the groove, thereby achieving good protection and improving the protection effect.
