Description

Technical Field

[0001] This utility model relates to the field of bearing cleaning devices, and in particular to a bearing cleaning pretreatment device. Background Technology

[0002] With the rapid development of the aviation industry, the safety and reliability of aircraft are receiving increasing attention. As a key component in aircraft transmission, the performance of aircraft bearings directly affects the operational safety of the aircraft. Therefore, regular cleaning and inspection of aircraft bearings is particularly important. Bearing cleaning pretreatment equipment is a device used to clean bearings and their accessories. It mainly removes oil, dust, rust, and other impurities to ensure that the bearings are in good working condition before assembly or use. This device uses solvent cleaning, ultrasonic cleaning, or jet cleaning technologies and is equipped with a filtration system to improve cleaning effect and efficiency. After cleaning, the bearings can avoid wear or performance degradation caused by residual contaminants, thereby extending the service life of the bearings and improving the operational stability of the equipment.

[0003] A search revealed Chinese patent publication number CN214718655U, which discloses a bearing cleaning pretreatment workbench, belonging to the field of bearing cleaning. The workbench includes a hollow box with a horizontal top surface. Inside the box is a waste collection bin with an open top. A waste inlet is located at the top of the box, below which is the waste collection bin. A paper holder is also provided on the top surface of the box for holding rolls of paper. While this application facilitates the removal of waste grease from bearings, in actual use, some impurities or waste grease adhere to the crevices within the bearing during cleaning. Rinsing and brushing cannot remove these confined impurities or waste grease, resulting in poor cleaning effectiveness. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing cleaning pretreatment device, which aims to improve the problem that the existing technology cannot remove impurities or waste grease in narrow gaps.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bearing cleaning pretreatment device, comprising a cleaning box, a partition fixedly connected to the middle of the inner wall of the cleaning box, an electric telescopic rod fixedly connected inside the partition, a limit groove formed on the outer wall of the electric telescopic rod, a movable column slidably connected inside the limit groove, rotating strips rotatably connected to the front and rear sides of the outer wall of the movable column, a movable plate fixedly connected to one end of the electric telescopic rod, sliding blocks slidably connected to the left and right sides of the inner wall of the movable plate, and a limit column fixedly connected to the front side of the two sliding blocks. The outer walls of the limiting posts are rotatably connected to the corresponding rotating bars. Rotating plates are rotatably connected to the left and right sides of the moving plate. A DC motor is fixedly connected to the outer wall of the rotating plate. A connecting rope is fixedly connected to the outer wall of the sliding block. The bottom of the connecting rope is fixedly connected to the rotating plate. A turntable is fixedly connected to the output end of the DC motor. An L-shaped post is fixedly connected to the bottom of the turntable. A baffle is slidably connected to the inner wall of the L-shaped post. Multiple ultrasonic devices are fixedly connected to the left and right sides of the outer wall of the cleaning box. A rinsing mechanism is provided on the left and right sides of the bottom of the inner wall of the cleaning box.

[0006] The above technical solution involves adding cleaning liquid to the cleaning tank, then pulling the baffle to place the bearing to be cleaned above the L-shaped column. The baffle is then lowered, and the electric telescopic rod is activated to retract. At this point, the rotating plates on both sides gradually rotate towards the bottom, while the sliding block drives the limiting column to move apart above the moving plate, causing the rotating bar to rotate. When the rotating plates on both sides are perpendicular to the cleaning tank, the electric telescopic rod continues to retract, causing the entire moving plate to move to the bottom and the moving column to move within the limiting groove. Ultimately, the bearing is immersed in the cleaning liquid. Then, the ultrasonic equipment is activated to perform ultrasonic cleaning on the bearing, while the DC motor drives the turntable to rotate. This causes the upper structure and the bearing to rotate in the cleaning liquid, resulting in a more thorough cleaning.

[0007] As a further description of the above technical solution:

[0008] The rinsing mechanism includes multiple limiting blocks, which are fixedly connected to the bottom of the inner wall of the cleaning box. Filter collection screens are provided on both the left and right sides of the bottom of the inner wall of the cleaning box. Multiple fixing blocks are fixedly connected to the bottom of the inner wall of the filter collection screens. Annular tubes are provided on the inner walls of the multiple fixing blocks. Multiple nozzles are connected to the outer walls of the annular tubes. An air inlet pipe is provided on the front side of the outer wall of the cleaning box. The outer wall of the air inlet pipe penetrates the cleaning box and is connected to a T-connector. Flexible hoses are connected to the left and right sides of the T-connector, and the bottoms of the flexible hoses are respectively connected to the tops of the corresponding annular tubes.

[0009] The above technical solution involves blowing air into the air inlet pipe through an external air supply device. The gas enters the three-way pipe through the air inlet pipe, then enters the annular pipe through the hose, and finally is sprayed out through the nozzle. In the cleaning fluid, a large number of bubbles wash the bearing, thereby flushing down the impurities in the bearing. These impurities then fall into the filter collection screen. The limiting block restricts the position of the filter collection screen, ensuring that it will not move during use, thus further cleaning the bearing and ensuring the thoroughness of the cleaning.

[0010] As a further description of the above technical solution:

[0011] A column is fixedly connected to the top of the movable plate, and a warning light is fixedly connected to the top of the column.

[0012] The above technical solution allows operators to be alerted when a malfunction occurs via a pillar and warning lights.

[0013] As a further description of the above technical solution:

[0014] The front left and right sides of the outer wall of the cleaning box are connected to drain pipes, and the outer wall of the drain pipes is provided with pipe covers.

[0015] The above technical solution allows for easy drainage of sewage through a drain pipe, while the pipe cover prevents sewage from being discharged.

[0016] As a further description of the above technical solution:

[0017] A nameplate is fixedly connected to the left side of the front of the outer wall of the cleaning box, and a warning sign block is fixedly connected to the right side of the front of the outer wall of the cleaning box.

[0018] The above technical solution allows the nameplate to record the equipment model and the warning sign block to remind operators of precautions.

[0019] As a further description of the above technical solution:

[0020] A U-shaped column is fixedly connected to the right side of the outer wall of the cleaning box, and a sponge column is fixedly connected to the outer wall of the U-shaped column.

[0021] The above technical solution allows the device to be pushed using a U-shaped column, and the comfort of the U-shaped column can be improved using a sponge column.

[0022] As a further description of the above technical solution:

[0023] Rotating blocks are rotatably connected to the four corners of the bottom of the outer wall of the cleaning box, and movable wheels are rotatably connected to the inner wall of the rotating blocks.

[0024] The above technical solution allows the equipment to be easily moved by using rotating blocks and moving wheels.

[0025] As a further description of the above technical solution:

[0026] The front side of the movable plate is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the sliding block.

[0027] The above technical solution allows the sliding block to slide more smoothly through the sliding groove.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the bearing is placed on the L-shaped column by operating the baffle. After the baffle is lowered, the electric telescopic rod is activated to retract. The rotating plate rotates to the bottom, and the sliding block pushes the limit column and the rotating bar to rotate. When the rotating plate is vertical, the moving plate descends, and the bearing is immersed in the cleaning fluid. Then, the ultrasonic equipment and DC motor are turned on to make the turntable rotate, so that the bearing is thoroughly cleaned in the cleaning fluid.

[0030] 2. In this utility model, air is blown into the air intake pipe through the air supply device, then enters the annular pipe through the three-way pipe and the hose, and finally sprays out from the nozzle to form bubbles to clean the bearing. During the cleaning process, impurities are washed down and fall onto the filter screen. The limiting block ensures that the filter screen is fixed in position, which can ensure the thoroughness of the bearing cleaning. Attached Figure Description

As the cleaning box 1 retracts, the rotating plates 11 pulled up on both sides gradually rotate towards the bottom. At the same time, the sliding block 9 drives the limiting column 10 to move apart above the moving plate 8, and drives the rotating bar 7 to rotate. When the rotating plates 11 on both sides are perpendicular to the cleaning box 1, the electric telescopic rod 4 continues to retract, which will cause the entire moving plate 8 to move towards the bottom, and will drive the moving column 6 to move in the limiting groove 5. The output end of the DC motor 13 is fixedly connected to the turntable 14, and the DC motor 13 drives the turntable 14 to rotate. The bottom of the turntable 14 is fixedly connected to the L-shaped column 15, and the inner wall of the L-shaped column 15 is slidably connected to the baffle 16.

At the same time, the sliding block 9 drives the limiting column 10 to move away from each other above the moving plate 8, and drives the rotating bar 7 to rotate. When the rotating plates 11 on both sides are perpendicular to the cleaning tank 1, the electric telescopic rod 4 continues to retract, which will cause the entire moving plate 8 to move to the bottom, and will drive the moving column 6 to move in the limiting groove 5, so that the bearing is finally immersed in the cleaning liquid. Then, the ultrasonic equipment 17 is activated to perform ultrasonic cleaning on the bearing, and at the same time, the DC motor 13 is activated to drive the turntable 14 to rotate, so that the structure above and the bearing rotate in the cleaning liquid, making the cleaning more thorough.

The bottom of the flexible hoses 208 are connected to the top of the corresponding annular pipes 204. Air is blown into the air inlet pipe 206. The gas enters the three-way pipe 207 through the air inlet pipe 206, then enters the annular pipe 204 through the flexible hoses 208, and finally is sprayed out through the nozzle 205. The bearing is flushed in the cleaning fluid with a large number of bubbles.

The nameplate 22 can record the model of the equipment, and the warning sign block 23 can remind the operator of precautions.

[0045] Reference Figure 1 , Figure 2 and Figure 4 A U-shaped column 24 is fixedly connected to the right side of the outer wall of the cleaning box 1. A sponge column 25 is fixedly connected to the outer wall of the U-shaped column 24.

[0047] Working principle: First, after injecting cleaning liquid into the cleaning tank 1, pull the baffle 16 to place the bearing to be cleaned on the L-shaped column 15. Then, reset the baffle 16. Next, start the electric telescopic rod 4 to retract. At this time, the rotating plates 11 on both sides will gradually rotate towards the bottom. At the same time, the sliding block 9 pulls the limiting column 10 to move away from each other above the moving plate 8, and drives the rotating bar 7 to rotate. When the rotating plates 11 on both sides are in a vertical state in the cleaning tank 1, the electric telescopic rod 4 continues to retract, which will cause the entire moving plate 8 to move towards the bottom and drive the moving column 6 to slide in the limiting groove 5 until the bearing is completely immersed in the cleaning liquid. Then, start the ultrasonic equipment 17 to perform ultrasonic cleaning on the bearing, and simultaneously start the DC... Motor 13 drives turntable 14 to rotate, which in turn drives the upper structure and bearings to rotate in the cleaning fluid, ensuring a more thorough cleaning process. Air is injected into the air inlet pipe 206 through the rinsing mechanism 2 via an external air supply device. The air flows into the three-way pipe 207 through the air inlet pipe 206, then into the annular pipe 204 through the hose 208, and finally released through the nozzle 205. During this process, a large number of bubbles are formed in the cleaning fluid, which flush the bearing to remove impurities inside the bearing. Subsequently, the impurities are deposited on the filter collection screen 202. The function of the limiting block 201 is to fix the position of the filter collection screen 202 to ensure that it does not shift during use, thereby enhancing the cleaning effect of the bearing and ensuring the cleanliness of the bearing.
