Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder cleaning technology, and in particular to a cleaning device for hydraulic cylinder production. Background Technology

[0002] A hydraulic cylinder, also known as a hydraulic caliper, is an important actuator in a hydraulic system. It converts hydraulic energy into mechanical energy to achieve linear reciprocating motion or oscillating motion. During the machining of hydraulic cylinders, processes such as cutting, grinding, and drilling generate a large amount of metal shavings, sand particles, and other impurities. If these residues are not thoroughly removed, they will wear down the seals and scratch the inner wall of the cylinder during subsequent use, leading to leaks and performance degradation. Therefore, cleaning equipment is needed to clean the hydraulic cylinder. This equipment is an industrial device used to remove oil, metal shavings, cutting fluid, carbon deposits, rust, and other contaminants from the inside and surface of the hydraulic cylinder.

[0003] When cleaning hydraulic cylinders using cleaning equipment, the cylinders are usually fixed to the cleaning equipment and then cleaned with a brush. However, since the outer diameter of the brush is fixed, the brush needs to be replaced when cleaning hydraulic cylinders with a larger inner diameter, which is troublesome and inconvenient for the flexible use of the cleaning equipment.

[0038] 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.

[0039] Reference Figure 1-8 An embodiment of this utility model provides a cleaning device for hydraulic cylinder production, comprising a frame 1, a housing 7 fixedly connected to the top of the frame 1, electric guide rails 37 fixedly connected to both sides of the top of the frame 1, sliders 36 slidably connected inside the two electric guide rails 37, a fixed frame 6 fixedly connected to the top of the sliders 36, a groove 34 opened on one side of the fixed frame 6, clamping blocks 35 slidably connected to both ends of the groove 34, springs 33 fixedly connected to one side of the two clamping blocks 35, insertion holes 31 opened on both sides of the bottom of the fixed frame 6, fixing rods 28 inserted into the two insertion holes 31, fixing seats 5 fixedly connected to the top of the two fixing rods 28, motors 30 fixedly connected to one side of the two fixing seats 5, rollers 29 fixedly connected to the driving ends of the two motors 30 through the fixing seats 5, and springs 32 fixedly connected to the bottom of the two fixing rods 28, with one end of each spring 32 fixedly connected to the bottom wall of the two insertion holes 31.

[0040] The elastic force of spring 2 33 will not cause the clamping block 35 to clamp the oil cylinder too tightly, so that the oil cylinder can rotate under the drive of roller 29.

[0041] Place the oil cylinder that needs to be cleaned on the top of the fixed frame 6, and place the two clamping blocks 35 on the outside of the oil cylinder respectively. Use the second spring 33 to pull the two clamping blocks 35 to move to both sides to clamp and fix the oil cylinder. At the same time, the first spring 32 will push the fixed seat 5 to move upward so that the roller 29 can lift the oil cylinder.

[0042] An electric guide rail 11 is fixedly connected to one side of the outer shell 7. A slider 10 is slidably connected inside the electric guide rail 11. A push rod 15 is fixedly connected to one side of the slider 10. One end of the push rod 15 passes through the side wall of the outer shell 7. The push rod 15 is designed as a cavity structure with openings at both ends. A base plate 24 is fixedly connected to one end of the push rod 15. A plurality of evenly distributed grooves 23 are opened on one side of the base plate 24. A pull rod 26 is slidably connected inside each of the plurality of grooves 23. A brush 14 is fixedly connected to one end of the pull rod 26.

[0043] The electric guide rail 2 37 is activated to push the slider 2 36, which in turn drives the fixing frame 6 into the housing 7. Then, the electric guide rail 1 11 drives the slider 10 to push the push rod 15 and the base plate 24 into the oil cylinder, so that the brush 14 can clean the inner wall of the oil cylinder. At the same time, the motor 2 30 is activated to drive the roller 29 to rotate, which in turn drives the oil cylinder to rotate. The electric guide rail 1 11 drives the slider 10 to move alternately to both sides, thereby driving the push rod 15 and the brush 14 to reciprocate, so that the brush 14 can thoroughly clean the inner wall of the oil cylinder.

[0044] A side plate 22 is rotatably connected to the outer side of the push rod 15 near the base plate 24. A plurality of evenly distributed slots 21 are opened on one side of the side plate 22. A protrusion 27 is slidably connected inside the slots 21. The protrusion 27 is fixedly connected to the end of the pull rod 26 away from the brush 14. A motor 16 is fixedly connected to one side of the outer shell 7. A turntable 17 is fixedly connected to the drive end of the motor 16 through the side wall of the outer shell 7. One side of the turntable 17 is in close contact with the outer side of the side plate 22.

[0045] When using the brush 14 to clean the inner wall of the oil cylinder, the motor 16 can be started to drive the turntable 17 to rotate. The friction between the turntable 17 and the side plate 22 will drive the side plate 22 to rotate. During the rotation, the side plate 22 will drive the protrusion 27 to slide inside the slot 21 and cause the pull rod 26 to slide outside the bottom plate 24 inside the groove 23, thereby pushing the brush 14 to move outward. This allows the distance between the brush 14 and the edge of the bottom plate 24 to be adjusted according to the inner diameter of the oil cylinder, so that the brush 14 can always be in close contact with the side wall of the oil cylinder.

[0046] A water tank 4 is fixedly connected to the bottom wall of the frame 1. A filter plate 25 is fixedly connected inside the water tank 4. A telescopic water pipe 3 is connected to one side of the water tank 4. One end of the telescopic water pipe 3 passes through the side wall of the frame 1 and the push rod 15 and is connected to a nozzle 13. A water pump 2 is connected to the outer side of the middle part of the telescopic water pipe 3.

[0047] When cleaning the oil cylinder, the brush 14 can start the water pump 2 to pump clean water from the water tank 4 into the telescopic water pipe 3 and spray it from the nozzle 13 onto the side wall of the oil cylinder to assist the brush 14 in cleaning the oil cylinder. When the brush 14 moves inside the oil cylinder, the telescopic water pipe 3 will extend and retract according to the movement of the brush 14.

[0048] The other side of the water tank 4 is connected to a pipe 20. The middle outer side of the pipe 20 is connected to a water pump 38. One end of the pipe 20 passes through the side wall of the frame 1 and the outer shell 7 and is connected to a nozzle 18. The bottom of the nozzle 18 is fixedly connected to a cleaning brush 19. The top two sides of the shell are fixedly connected to cylinders 8. The output ends of the two cylinders 8 pass through the inner top wall of the outer shell 7 and are fixedly connected to the top two sides of the nozzle 18.

[0049] When the brush 14 cleans the inner wall of the oil cylinder, the cylinder 1 8 can be activated to push the nozzle 18 downward so that the cleaning brush 19 can contact the surface of the oil cylinder. At the same time, the water pump 2 38 is activated to pump the clean water inside the water tank 4 into the nozzle 18 through the pipe 20, and then spray it from the nozzle 18 onto the surface of the oil cylinder. At this time, the oil cylinder will rotate under the drive of the roller 29 so that the cleaning brush 19 can scrub the surface of the oil cylinder.

[0050] The top of the frame 1 has multiple evenly distributed drainage holes. After the clean water sprayed from the nozzle 18 and the nozzle 13 has cleaned the oil cylinder, it can flow into the water tank 4 through the drainage holes and use the filter plate 25 to filter the impurities attached to the clean water so that the clean water can be recycled.

[0051] A baffle 9 is provided at the front end of the outer shell 7. Cylinders 12 are fixedly connected to both sides of the outer shell 7. The output ends of the two cylinders 12 are fixedly connected to the top two sides of the baffle 9 respectively. When the slider 36 pushes the fixing frame 6 and the oil cylinder into the inner shell 7, the cylinders 12 can be activated to drive the baffle 9 to move downward, so that the baffle 9 can cover the outer shell 7, thereby preventing the water from splashing out from the inside of the outer shell 7 when the nozzle 18 and the nozzle 13 spray water.

[0052] Working principle: The second cylinder 12 pushes the baffle 9 upwards to open the outer casing 7. Then, the hydraulic cylinder is placed on top of the fixed frame 6, and the two clamping blocks 35 are placed on the outside of the hydraulic cylinder. Spring 33 pulls the two clamping blocks 35 to the sides to clamp and fix the hydraulic cylinder. The spring pushes the fixed rod 28 and the fixed seat upwards, allowing the roller 29 to lift the hydraulic cylinder. The second electric guide rail 37 pushes the second slider 36, causing the fixed frame 6 to enter the outer casing 7. The second cylinder 12 then moves the baffle 9 to seal the outer casing 7. The first motor 16 drives the turntable 17 to rotate, causing the side plate 22 to rotate. This drives the protrusion 27 to slide inside the slot 21, thereby lifting... The movable rod 26 slides outward from the bottom plate 24 inside the groove 23, thereby pushing the brush 14 to move outward to adjust the distance between the brush 14 and the edge of the bottom plate 24 according to the inner diameter of the oil cylinder, so that the brush 14 can always be in close contact with the side wall of the oil cylinder. Then, the electric guide rail 11 drives the slider 10 to push the push rod 15 and the bottom plate 24 into the oil cylinder, so that the brush 14 can clean the inner side wall of the oil cylinder. At the same time, the motor 20 is started to drive the roller 29 to rotate, thereby rotating the oil cylinder. The electric guide rail 11 drives the slider 10 to move alternately to both sides, thereby driving the push rod 15 and the brush 14 to reciprocate, so that the brush 14 can thoroughly clean the inner wall of the oil cylinder.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
