Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic oil cylinder production, in particular to a cleaning device for the production and processing of hydraulic oil cylinders. Background Art As an indispensable key component in modern industrial equipment, the performance and quality of hydraulic cylinders directly impact the operational efficiency and stability of various mechanical systems. A hydraulic cylinder is an actuator that converts hydraulic energy into mechanical energy. Through a sealed working chamber, it utilizes liquid pressure to propel a piston in reciprocating motion, thereby performing external work. Hydraulic cylinders typically consist of a cylinder barrel, piston, piston rod, seals, and connectors. Their compact structure, smooth transmission, and high output have led to their widespread application in metallurgy, mining, construction machinery, shipbuilding, aerospace, and other fields.

[0002] However, during the production and processing of hydraulic cylinders, cleaning is a crucial step in ensuring their quality and performance. Because hydraulic cylinders withstand the impact and friction of high-pressure fluids during operation, extremely high cleanliness requirements are placed on the inside and outside of the cylinder barrel. Any residual impurities, oil stains, or metal shavings can compromise the sealing effectiveness of seals, leading to leakage and even increasing wear on the cylinder barrel and piston, shortening the service life of the hydraulic cylinder.

[0003] Currently, existing methods for cleaning hydraulic cylinder outer liners have significant limitations. Most cleaning equipment can only effectively clean the outer surface of the outer liners, but cannot penetrate deeply into the inner surface for thorough cleaning. Therefore, after cleaning the outer surface, workers usually have to manually clean the inner surface of the outer liners. This cleaning method is not only inefficient, but also requires workers to spend a lot of time and energy to handle each outer liners during the cleaning process. This problem is particularly prominent in large-scale production. Summary of the Invention

[0004] The present invention provides a cleaning device for producing and processing a hydraulic oil cylinder, which is used to solve the defects in the prior art.

[0005] The present invention is achieved through the following technical solutions: A cleaning device for the production and processing of a hydraulic cylinder comprises a driving wheel, a driven wheel, a synchronous belt for transmitting the driving wheel and the driven wheel, a flat plate fixedly arranged between the synchronous belts and supporting the outer cylinder sleeve to move to the driven wheel, the driving wheel is driven by a driving motor to rotate 60 degrees counterclockwise each time, the synchronous belt is provided with through holes at equal intervals along the length direction, the driven wheel is rotatably sleeved on the circular shaft through a sealed bearing and is rotatably sealed with the circular shaft, six cleaning grooves are evenly provided along the circumference of the driven wheel, a rotating plate driven by a driving mechanism is provided in the cleaning groove, a support plate is rotatably connected to the rotating plate, a cavity is provided in the rotating plate, a connecting pipe is rotatably connected to the cleaning groove through a bearing, and one end of the connecting pipe is fixedly connected to the rotating plate and communicated with the cavity, both sides and the middle vertical of the rotating plate are An outer cleaning pipe and an inner cleaning pipe which are directly connected and communicated with the cavity and have closed ends and cleaning holes on the side are provided, and the inner cleaning pipe passes through the support plate; a water cavity and an air cavity are provided in the circular shaft, and the water cavity and the air cavity are respectively communicated with the water pump and the air pump; the water pump and the air pump are both high-pressure pumps, and the water pump is arranged in the water source, and the water cavity and the air cavity are fan-shaped structures along the vertical section of the circular shaft, and the angles of the vertical sections of the water cavity and the air cavity are 280 degrees to 10 degrees and 130 degrees to 280 degrees in the clockwise direction respectively, and the air cavity and the water cavity are both provided with inner transparent grooves outwardly, and an outer transparent groove which can be opposite to and fit with the inner transparent groove is provided outwardly on the inner wall of the driven wheel, and the other end of the connecting pipe is communicated with the outer transparent groove, and a water baffle which fits with the synchronous belt is fixedly provided laterally below the driven wheel, and a circular hole which can be opposite to the cleaning groove is provided on the water baffle.

[0006] When the present application is in use, the outer cylinder sleeve of the hydraulic oil cylinder is first placed in the through hole on the synchronous belt and placed under the support of the flat plate and falls from the through hole. Then the driving motor is started to rotate 60 degrees each time and ensure that the cleaning groove is opposite to the corresponding through hole, so as to ensure that the outer cylinder sleeve of the hydraulic oil cylinder falls into the cleaning groove and is supported by the support plate. At the same time, the inner cleaning pipe is located in the outer cylinder sleeve and the outer cleaning pipe is located on the outside of the outer cylinder sleeve. At the same time, when the driven wheel rotates with the driving wheel, the rotation of the driven wheel drives the outer transparent groove to rotate synchronously, so that the outer transparent groove is first connected with the inner transparent groove in the water cavity, so that water enters the connecting pipe through the water cavity, and then It enters the cavity through the connecting pipe and enters the corresponding outer cleaning pipe and inner cleaning pipe from the cavity to realize the cleaning of the inside and outside of the outer cylinder liner. At the same time, the rotating plate rotates under the drive mechanism to drive the outer cleaning pipe and the inner cleaning pipe to rotate, so as to realize the complete cleaning of the inside and outside of the outer cylinder liner and ensure that all positions are cleaned. Then the driven wheel continues to hang, so that the corresponding outer transparent groove is opposite to the inner transparent groove at the air cavity, so as to realize the spray drying of the outer wall and inner wall of the outer cylinder liner, and realize the drying of the outer cylinder liner. Then when the driven wheel rotates to 180 degrees, the outer cylinder liner falls off from the cleaning groove under the action of gravity, thereby realizing the cleaning of the inside and outside of the outer cylinder liner.

[0007] Preferably, the drive mechanism includes an annular bevel gear coaxial with the circular shaft and fixedly disposed behind the circular shaft. The driven wheel is provided with a rotation groove extending through the driven wheel from front to back. The rotation groove is provided with a rotating bevel gear meshing with the annular bevel gear. The rotating bevel gear is fixedly sleeved on the connecting tube. The rotating bevel gear rotates along the circular shaft driven by the connecting tube. Since the rotating bevel gear meshes with the fixed annular bevel gear, the rotating bevel gear simultaneously rotates while rotating. The rotation of the rotating bevel gear drives the rotation of the connecting tube, thereby achieving rotation of the rotating plate. Thus, the rotation of the driven wheel can be used as a driving force to drive the rotation of the rotating plate.

[0008] Preferably, scrapers are fixedly provided on the outer cleaning pipe and the inner cleaning pipe along their length direction, and the scrapers are in contact with the corresponding outer and inner walls of the outer cylinder sleeve. The scrapers can be used to clean the inner and outer walls of the outer cylinder sleeve more thoroughly.

The electromagnet can adsorb the outer cylinder sleeve to avoid the outer cylinder sleeve rotating when scraping the outer cylinder sleeve, and the first fixed rod and the second fixed rod are respectively located at 0 degrees and 180 degrees of the driven wheel and are controlled by the delay device, which can ensure that the electromagnet is out of power when the outer cylinder sleeve falls into the cleaning tank, and then after a delay period, the electromagnet is energized again to achieve adsorption of the outer cylinder sleeve, and the power is cut off at 180 degrees, which ensures that the outer cylinder sleeve can fall under the action of gravity.

[0010] The cam is provided with a plurality of holes, the holes being arranged on the inner wall of the cam and the holes being arranged on the sides of the cam, so that the cam can be connected with the outer wall of the cam and the holes can be adjusted. Among them, when the cleaning tank is facing upward, water or gas is pushed upward under the action of pressure, so that when the outer hole and the inner hole are connected, the gas or water is released, and the air outlet groove is sealed through the side of the air outlet hole. When it is rotated to 180 degrees, the air cavity is connected with the connecting pipe, and the controller controls the second electromagnet to be energized, so that the second electromagnet adsorbs the iron sheet, and then the outer hole and the inner hole are misaligned, the jet pipe enters the middle hole and the gas is ejected outward through the air outlet groove and the middle hole, so as to blow the outer cylinder sleeve, prevent the outer cylinder sleeve from being difficult to fall off under the action of the friction between the scraper and the first electromagnet, and thus use the gas dried to the outer cylinder sleeve as power to achieve rapid shedding of the outer cylinder sleeve.

[0011] Preferably, when the middle hole extends outward, its diameter decreases and forms a tapered hole, which can increase the flow rate and make the spray more powerful.

[0012] Preferably, the outer hole becomes larger in diameter as it extends outwards and forms a trumpet hole, which can achieve a larger diffusion area and achieve better cleaning and drying.

The synchronous belt passes through the transmission wheel and then rebounds around the first guide transmission wheel, and then is transmitted to the second guide transmission wheel through the first guide transmission wheel, and then is transmitted upward at 90 degrees to the driving wheel to form a closed loop. The through hole located at 180 degrees from the driven wheel and the corresponding through hole on the synchronous belt between the guide wheel and the first transmission guide wheel are directly opposite to each other. In this way, the cylinder sleeve dropped at 180 degrees can fall on the through hole on the synchronous belt below and be transmitted forward along the through hole, making it convenient for the staff to remove it.

[0014] Preferably, a circular groove is provided on the rotating plate, which is rotatably connected to a circular tube via a bearing, and the circular tube is vertically connected to the support plate. A circular hole is provided on the support plate, and the middle cleaning tube passes through the circular tube and communicates with the inside of the cavity.

It includes a driving wheel 1, a driven wheel 2, a synchronous belt 3 that transmits the driving wheel 1 and the driven wheel 2, and a flat plate fixedly arranged between the synchronous belts 3 and supporting the outer cylinder sleeve 5 to move to the driven wheel 2.

The driven wheel has six cleaning grooves 4 evenly opened along its circumference. The cleaning grooves 4 are provided with a rotating plate 7 driven by the driving mechanism. The rotating plate 7 is rotatably connected to the support plate 6. The rotating plate 7 has a cavity formed therein. The connecting pipe 16 is rotatably connected to the cleaning groove 4 through a bearing. One end of the connecting pipe 16 is fixedly connected to the rotating plate 7 and communicates with the cavity. The two sides and the middle of the rotating plate 7 are vertically connected and connected to the cavity. An outer cleaning pipe 8 and an inner cleaning pipe 9 are provided with closed ends and cleaning holes on the side, and the inner cleaning pipe 9 passes through the support plate 6; a water chamber 10 and an air chamber 11 are provided in the circular shaft 29, and the water chamber 10 and the air chamber 11 are connected to the water pump and the air pump respectively; the water chamber 10 and the air chamber 11 are fan-shaped along the vertical section of the circular shaft 29, and the angles of the vertical sections of the water chamber 10 and the air chamber 11 are 280 degrees to 10 degrees and 130 degrees to 280 degrees in the clockwise direction respectively. The air chamber 11 and the water chamber 10 are both provided with an inner transparent groove 12 outwardly, and the inner transparent groove 12 is provided at 0 degrees, 180 degrees, 240 degrees and 300 degrees, that is, the air chamber 11 and the water chamber 10 are both provided with two inner transparent grooves 12, and the inner wall of the driven wheel 2 is provided with an outer transparent groove 13 which is opposite to and fits with the inner transparent groove 12, and the other end of the connecting pipe 16 is connected to the outer transparent groove 13.

[0022] A water baffle 30 is fixedly provided below the driven wheel and is fitted with a synchronous belt. A circular hole is provided on the water baffle 30 that is opposite to the cleaning tank. The water baffle 30 serves to block water and prevent it from flowing to the falling outer cylinder sleeve.

[0023] The driving mechanism includes an annular bevel gear 14 that is coaxial with the circular shaft 29 and fixedly arranged behind the circular shaft 29. A rotating groove that passes through the driven wheel 2 from front to back is opened on the driven wheel 2. A rotating bevel gear 15 that meshes with the annular bevel gear 14 is provided in the rotating groove. The rotating bevel gear 15 is fixedly sleeved on the connecting pipe 16.

[0024] When the present application is in use, firstly, the outer cylinder sleeve 5 of the hydraulic oil cylinder is placed downwardly in the through hole on the synchronous belt 3 and is placed under the support of the flat plate and falls from the through hole. Then the driving motor is started to rotate 60 degrees each time and ensure that the cleaning groove 4 is opposite to the corresponding through hole, so as to ensure that the outer cylinder sleeve 5 of the hydraulic oil cylinder falls into the cleaning groove 4 and is supported by the support plate 6. At the same time, the inner cleaning pipe 9 is located in the outer cylinder sleeve 5, and the outer cleaning pipe 8 is located outside the outer cylinder sleeve 5. At the same time, when the driven wheel 2 rotates with the driving wheel 1, the rotation of the driven wheel 2 drives the outer transparent groove 13 to rotate synchronously, so that the outer transparent groove 13 first rotates with the water cavity 10 The inner transparent groove 12 is communicated with the inner transparent groove 12, so that water enters the connecting pipe 16 through the water cavity 10, and then enters the cavity through the connecting pipe 16, and enters the corresponding outer cleaning pipe 8 and inner cleaning pipe 9 from the cavity, thereby realizing the inside and outside cleaning of the outer cylinder sleeve 5. At the same time, the rotating bevel gear 15 rotates along the circular axis 29 driven by the connecting pipe 16. Since the rotating bevel gear 15 is engaged with the fixed annular bevel gear 14, the rotating bevel gear 15 rotates while rotating. The rotation of the rotating bevel gear 15 drives the rotation of the connecting pipe 16 to realize the rotation of the rotating plate 7, so that the rotation of the driven wheel 2 can be used as the driving force to drive the rotation of the rotating plate 7. The rotation of the rotating plate 7 drives the outer cleaning tube 8 and the inner cleaning tube 9 to rotate, so as to completely clean the inside and outside of the outer cylinder liner 5 and ensure that all positions are cleaned. Then the driven wheel 2 continues to hang, so that the corresponding outer transparent groove 13 is opposite to the inner transparent groove 12 at the air cavity 11, so as to realize the spray drying of the outer wall and inner wall of the outer cylinder liner 5, and realize the drying of the outer cylinder liner 5. Then when the driven wheel 2 rotates to 180 degrees, the outer cylinder liner 5 falls off from the cleaning groove 4 under the action of gravity, thereby realizing the cleaning of the inside and outside of the outer cylinder liner 5.

[0025] The outer cleaning pipe 8 and the inner cleaning pipe 9 are both fixedly provided with scrapers along their length direction. The scrapers are in contact with the corresponding outer wall and inner wall of the outer cylinder sleeve 5. The scrapers can be used to clean the inner wall and outer wall of the outer cylinder sleeve 5 more thoroughly.

[0026] A first electromagnet 17 is fixedly provided on the inner wall of the outer end portion of the cleaning tank 4 along its circumference, and the end of the first electromagnet 17 is in contact with the outer wall of the outer cylinder sleeve 5. A sensing unit 18 is fixedly provided on the connecting pipe 16, and the sensing unit 18 is located at the rotating groove. A first fixed rod and a second fixed rod are fixedly provided on the front side of the driven wheel 2, and a receiving unit is provided on the first fixed rod and the second fixed rod. The first fixed rod and the second fixed rod are respectively located at 0 degrees and 180 degrees of the driven wheel 2. The receiving unit is connected to the controller signal, the controller controls the delay device, and the delay device controls the first electromagnet 17 to be powered off. The electromagnet can adsorb the outer cylinder sleeve 5 to prevent the outer cylinder sleeve 5 from rotating when scraping the outer cylinder sleeve 5, and the first fixed rod and the second fixed rod are respectively located at 0 degrees and 180 degrees of the driven wheel 2 and are controlled by the delay device, which can ensure that the electromagnet is out of power when the outer cylinder sleeve 5 falls into the cleaning tank 4, and then after a period of delay, the electromagnet is energized again to achieve adsorption of the outer cylinder sleeve 5, and the power is cut off at 180 degrees to ensure that the outer cylinder sleeve 5 can fall under the action of gravity.

[0027] The inner cleaning pipe 9 includes a fixed pipe and a movable pipe 82 which is slidably sealed in the fixed pipe. A sliding groove is provided on the inner wall of the fixed pipe along its length. A slider is slidably fitted in the sliding groove. The slider is fixedly connected to the movable pipe 82. The fixed pipe is communicated with the cavity. An outer hole 19 and an inner hole 20 are respectively provided on the movable pipe 82 and the outer pipe 81. An air outlet is provided on the inner wall of the outer end face of the outer pipe 81. An air outlet is provided on the outer end face of the inner pipe vertically connected to the air jet pipe 21. The outer end of the air jet pipe 21 is closed and an air outlet groove is provided on the side. The tube 81 is also provided with a middle hole 22, which is coaxial with and connected to the air outlet. The diameter of the middle hole 22 is larger than that of the air outlet. The middle hole 22 is connected to the outside world. When the outer hole 19 is opposite to the inner hole 20, the air outlet groove is sealed by the side wall of the air outlet. When the air outlet groove is located in the middle hole 22, the outer hole 19 and the inner hole 20 are misaligned. The opposite surfaces of the inner walls of the inner tube and the outer tube 81 are respectively fixed with relative second electromagnets 23 and iron sheets 24. The second electromagnet 23 is controlled by the controller and is energized at 180 degrees. Among them, when the cleaning tank 4 is facing upward, water or gas is pushed upward under the action of pressure, so that when the outer hole 19 and the inner hole 20 are connected, the gas or water is released, and the air outlet groove is sealed through the side of the air outlet. When it is rotated to 180 degrees, the air cavity 11 is connected with the connecting pipe 16, and the controller controls the second electromagnet 23 to be energized, so that the second electromagnet 23 adsorbs the iron sheet 24, and then the outer hole 19 and the inner hole 20 are misaligned, the jet pipe 21 enters the middle hole 22 and the gas is ejected outward through the air outlet groove and the middle hole 22, so as to blow the outer cylinder sleeve 5, prevent the outer cylinder sleeve 5 from being difficult to fall off under the action of the friction between the scraper and the first electromagnet 17, thereby using the gas dried to the outer cylinder sleeve 5 as power to achieve rapid shedding of the outer cylinder sleeve 5.

[0028] When the middle hole 22 extends outward, its diameter decreases and forms a tapered hole. The tapered hole can increase the flow rate and make the spray more powerful.

[0029] The outer hole 19 becomes larger in diameter as it extends outwards and forms a trumpet hole. The trumpet hole can achieve a larger diffusion area, thereby achieving better cleaning and drying.

[0030] The machine frame also includes a guide wheel 25, a first guide transmission wheel 26, and a second guide transmission wheel 27. The top surface of the guide wheel 25 and the bottom surface of the transmission wheel are located on the same horizontal line plane, and the bottom surface of the guide wheel 25 and the top surfaces of the first and second guide transmission wheels 26 and 27 are located on the same horizontal plane. The synchronous belt 3 passes through the transmission wheel and then rebounds around the first guide transmission wheel 26. It is then transmitted to the second guide transmission wheel 27 through the first guide transmission wheel 26 and is transmitted upward at 90 degrees to the driving wheel 1 to form a closed loop. The through hole at 180 degrees of the driven wheel 2 and the corresponding through hole on the synchronous belt 3 between the guide wheel 25 and the first transmission guide wheel 25 are directly opposite each other. This allows the cylinder sleeve that falls at 180 degrees to fall on the through hole on the synchronous belt 3 below and be transmitted forward along the through hole, making it convenient for the staff to remove it.

[0031] A circular groove is provided on the rotating plate 7, which is rotatably connected to the circular tube 28 through a bearing. The circular tube 28 is vertically connected to the support plate 6. A circular hole is provided on the support plate 6, and the middle cleaning pipe passes through the circular tube 28 and communicates with the inside of the cavity.

[0032] The use of the present application can firstly realize the synchronous automatic cleaning of the inside and outside of the outer cylinder sleeve 5, saving the time and physical effort consumed by the staff for manual cleaning. At the same time, due to the synchronous cleaning, the cleaning efficiency can be improved.

[0033] At the same time, while meeting the cleaning requirements, the rotation of the driven wheel 2 is used as power to realize the rotation of the external cleaning tube 8 and the internal cleaning tube 9, ensuring that the cleaning is more uniform and thorough, and when it is rotated to 180 degrees, the power of the spray can be used to realize the rapid drop of the outer cylinder sleeve 5.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
