Abstract
Description
Technical Field
[0001] This utility model relates to the field of nitrogen spring technology, specifically a cleaning device for cleaning oil stains on the surface of nitrogen springs. Background Technology
[0002] As is well known, a nitrogen spring is an elastic element that uses high-pressure nitrogen as its working medium. It utilizes the pressure changes generated by nitrogen at different volumes to provide elastic force. It has advantages such as small size, large elastic force, long stroke, smooth operation, and long service life. It is widely used in many fields such as molds, automobiles, and aerospace, and can meet the needs for elastic force and cushioning in different scenarios.
[0003] Nitrogen springs may have a protective oil film left over from the anti-rust spraying process during manufacturing. After long-term exposure, this type of oil may mix with environmental pollutants to form a sticky substance. At the same time, if the seals age or the parts wear during use, the internal lubricating grease may leak to the surface, forming oil stains.
[0004] Residual oil may trap corrosive substances (such as moisture and salt), accelerating metal oxidation. Cleaning makes subsequent rust prevention treatment easier. Oil can interfere with coating adhesion, leading to uneven lubrication or protective layer on the spring surface, affecting elasticity and durability. Sticky oil may also attract dust or metal debris, increasing the risk of abnormal friction or jamming between moving parts. Therefore, it is necessary to clean the oil on the surface of nitrogen springs regularly.
[0005] As is known, in existing technologies, nitrogen springs are generally cleaned manually. However, to improve cleaning efficiency, mechanical equipment is used. In this process, the nitrogen spring is first fixed in place, and then a cleaning assembly rotates to clean its surface. However, existing nitrogen springs are of varying sizes, and the cleaning assembly wears down over time, requiring frequent replacement of the cleaning equipment, which presents certain drawbacks. Utility Model Content
[0006] The purpose of this invention is to provide a cleaning device for cleaning oil stains on the surface of nitrogen springs, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for cleaning oil stains on the surface of a nitrogen spring, comprising a cleaning seat, a rotating disk rotatably connected to the cleaning seat, and a movable frame vertically slidably connected to the cleaning seat, with a nitrogen spring body installed between the movable frame and the rotating disk; the cleaning seat is provided with a cleaning part for cleaning the nitrogen spring body, the cleaning part including a mounting frame, a cleaning plate slidably connected within the mounting frame, and a fastening spring provided between the cleaning plate and the mounting frame, the elastic force of the fastening spring driving the cleaning plate to abut against the nitrogen spring body.
[0008] Furthermore, a servo motor is installed inside the cleaning seat, which is used to drive the rotating disk to rotate.
[0009] Furthermore, the cleaning plate is provided with an arc-shaped groove, which is adapted to the nitrogen spring body.
[0010] Furthermore, the arc-shaped groove is provided with multiple sets of friction stripes.
[0011] Furthermore, the rotating disk is also provided with a positioning unit for pre-fixing the nitrogen spring body.
[0012] Furthermore, the positioning unit includes multiple sets of positioning plates slidably connected to the rotating disk, and each positioning plate is provided with a positioning spring between itself and the rotating disk; the multiple sets of positioning plates are arranged in a circumferential array.
[0013] Furthermore, the cleaning seat is equipped with a servo cylinder, which drives the moving frame to slide vertically through a connecting unit.
[0014] Furthermore, the connecting unit includes multiple connecting rods fixedly connected to the movable frame. The connecting rods are slidably connected to the cleaning seat. The multiple connecting rods are fixedly connected to each other by a connecting plate, and the connecting plate is installed at the output end of the servo cylinder.
[0015] Furthermore, a rotating plate is rotatably connected to the top of the movable frame, the rotating plate is in intermittent contact with the nitrogen spring body, and a bearing is provided between the rotating plate and the movable frame.
[0016] Furthermore, a contact plate is also provided inside the rotating disk.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This cleaning device for cleaning oil stains on the surface of nitrogen springs rotates on a cleaning seat via a rotating disc, which in turn drives the nitrogen spring body to rotate together with the moving frame. Due to the elastic force of the fastening spring, the cleaning plate abuts against the nitrogen spring body. At this time, as the nitrogen spring body rotates, the cleaning plate cleans the oil stains on the surface of the nitrogen spring body, improving the cleaning efficiency of the oil stains on the surface of the nitrogen spring body. When the cleaning plate wears, it can automatically compensate by sliding under the elastic force of the fastening spring, so that the cleaning plate can always abut against the nitrogen spring body, improving the cleaning efficiency of the oil stains on the surface of the nitrogen spring body and achieving better results.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A nitrogen spring body 3 is installed between the movable frame 4 and the rotating disk 2. The cleaning seat 1 is provided with a cleaning part for cleaning the nitrogen spring body 3. The cleaning part includes a mounting frame 8, a cleaning plate 9 slidably connected inside the mounting frame 8, and a fastening spring 12 is provided between the cleaning plate 9 and the mounting frame 8.

[0028] Specifically, the cleaning device for cleaning oil stains on the surface of a nitrogen spring includes a cleaning seat 1, a rotating disk 2 rotatably connected to the cleaning seat 1, and a movable frame 4 vertically slidably connected to the cleaning seat 1.

Preferably, the cleaning plate is made of a material suitable for cleaning oil stains or a composite material; the structure and working principle of the cleaning plate will not be described in detail here. Furthermore, a fastening spring 12 is provided between the cleaning plate 9 and the mounting frame 8. The elastic force of the fastening spring 12 drives the cleaning plate 9 to abut against the nitrogen spring body 3. During use, the rotating disk 2 rotates on the cleaning seat 1, which in turn drives the nitrogen spring body 3 to rotate together with the moving frame 4. As the fastening spring 12 drives the cleaning plate to abut against the nitrogen spring body 3, the cleaning plate 9 cleans the oil stains on the surface of the nitrogen spring body 3 as the nitrogen spring body 3 rotates.
