Abstract
Description
Technical Field
[0001] This utility model belongs to the field of salute cannon technology, specifically relating to a structure for reducing scratches on the outer surface of the inner cylinder of a salute cannon balancing machine. Background Technology
[0002] The use of ceremonial cannons is special, and compared with general military equipment, ceremonial cannons receive more attention, so the requirements for their appearance and quality are higher.
[0003] However, during use, scratches often appear on the outer surface of the inner cylinder of the balancing machine, which seriously affects its appearance quality and the life of the parts. The existing solution to this problem is lubrication: applying lubricant during assembly. However, even with existing lubricants, scratches will still appear on the outer surface of the inner cylinder after a long period of use, which will still have an impact on it. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The technical problem to be solved by this utility model is: how to reduce scratches on the outer surface of the inner cylinder of the salute cannon balancing machine.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, this utility model provides a structure for reducing scratches on the outer surface of the inner cylinder of a ceremonial cannon balancing machine, including an inner cylinder 1, an outer cylinder 2, and an oil cup 3. The outer cylinder 2 has an extension section at its right end, and the inner surface of the extension section is set as a stepped surface. The oil cup 3 is located at the trunnion of the balancing machine. An oil groove is machined on the inner wall of the outer cylinder, and the oil groove is in contact with the inner cylinder. The oil groove is connected to the oil cup.
[0008] Furthermore, the oil tank is equipped with an oil injection nozzle.
[0009] (III) Beneficial Effects
[0010] Compared with the existing technology, the present invention has the following beneficial effects: it can completely improve the problem of scratches on the outer surface of the inner cylinder of the existing balancing machine of the salute cannon. Attached Figure Description
[0011] Figure 1 This is a cross-sectional view of the inner cylinder;
[0012] Figure 2 This is a cross-sectional view of the outer cylinder;
[0013] Figure 3 This is an assembly drawing for a balancing machine. Detailed Implementation
[0014] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0015] The structure for reducing scratches on the outer surface of the inner cylinder of the salute cannon balancing machine in this embodiment includes an inner cylinder 1, an outer cylinder 2, and an oil cup 3. An extension section is provided at the right end of the outer cylinder 2, and the inner surface of the extension section is set as a stepped surface. The oil cup 3 is located at the trunnion of the balancing machine. An oil groove is machined on the inner wall of the outer cylinder, and the oil groove is in contact with the inner cylinder. The oil groove is connected to the oil cup.
[0016] The design process is as follows:
[0017] 1. The outer surface of the inner cylinder has scratches, which affects the appearance. The outer cylinder is lengthened to prevent the scratched part of the inner cylinder from being exposed.
[0018] Second, after the outer cylinder is lengthened, it cannot completely cover the scratched part of the inner cylinder during the full stroke of the balancing machine. Therefore, the exposed part of the outer surface of the inner cylinder and the extended part of the outer cylinder are designed with steps to ensure that the exposed part of the inner cylinder does not contact the inner wall of the outer cylinder.
[0019] Third, an oil injection nozzle is designed at the trunnion, and an oil groove is machined on the inner wall of the outer cylinder to ensure that the sliding parts between the inner and outer cylinders can be fully lubricated.
[0020] This solved the problem of maintaining the existing structure of the ceremonial cannon balancing machine while reducing scratches on the outer surface of the inner cylinder of the balancing machine.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
