Description

Technical Field

[0001] The invention relates to the technical field of gun barrel laser cleaning equipment, and in particular to a gun barrel inner wall cleaning equipment. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] After the gun barrel fires a shell, the inner wall of the gun barrel needs to be cleaned. Currently, the inner wall of the gun barrel is cleaned by multiple soldiers at the same time. The soldiers use a pole with cotton cloth tied at one end to push and pull the pole to create friction between the cotton cloth and the inner wall of the gun barrel to clean the inner wall of the gun barrel. Residues will adhere to the inner wall, which will reduce the smoothness of the inner wall and increase the friction resistance. Therefore, corresponding equipment is needed to clean the inner wall, and laser cleaning can effectively remove impurities from the inner wall of the gun barrel.

[0004] However, the existing laser cleaning equipment usually has the following shortcomings: after cleaning, the smoke and charred materials generated inside will still adhere to the inner wall of the barrel. These attachments are difficult to clean, and there is room for improvement. In view of the above problems, a gun barrel inner wall cleaning device is proposed to solve the above problems.

Secondly, a hollow motor is arranged in the cleaning end head 2 to drive the cleaning end head 2 to rotate, so that the laser rotates and sweeps the inner wall of the barrel for cleaning. It is easy to imagine that an air curtain mechanism is also arranged on the cleaning end head 2 to prevent the smoke generated during the cleaning process from interfering with the laser equipment;

[0047] A walking mechanism 3, wherein the walking mechanism 3 is arranged on the laser cleaning tube 1 and is used to drive the laser cleaning tube 1 to move along the axis of the gun barrel;

[0049] The cleaning part 4 is arranged between the walking parts 31, and the cleaning part 4 is distributed in a ring shape and is transmission-connected with the walking parts 31. The cleaning part 4 is used for synchronously expanding with the walking parts 31 to contact the inner wall of the gun barrel and clean the inner wall.

[0050] When the present application is in use, the walking mechanism 3 and the cleaning part 4 provided on the laser cleaning tube 1 can be expanded synchronously and fit with the inner wall of the gun barrel. As the cleaning end 2 on the laser cleaning tube 1 is cleaned, the power generated by the walking mechanism 3 can drive the entire device to progress axially to perform uniform laser cleaning on the inner wall of the gun barrel. During the cleaning process, the attachments on the inner wall of the gun barrel can be removed by the roller brush of the cleaning part 4.

[0051] In this application, it should be noted that Figure 3As shown, the cleaning part 4 includes a fixing ring 41 arranged on the laser cleaning tube 1;

When in use, the plurality of cleaning rollers 43 are combined into a ring shape through the universal coupling 44 and the transmission rod 316. During the expansion process, the cleaning rollers 43 can be expanded synchronously with the expansion of the walking part 31.

[0062] At the same time, a second driving unit 317 connected to the transmission rod 316 is also provided in the walking bracket 311.
