Description

Technical Field

[0001] This invention relates to the field of valve tappet cleaning technology, specifically to a valve tappet cleaning device and cleaning method. Background Technology

[0002] Valve tappets are key transmission components in the valve train of internal combustion engines, connecting the camshaft and valves. Their core function is to convert the rotational motion of the camshaft into the reciprocating linear motion of the valve. The oil holes of the valve tappets play a vital role in the engine, serving as the key channel for engine oil to enter the interior of the tappet. Engine oil enters the side of the tappet body and the plunger passage through the oil holes, providing the necessary lubrication and pressure source for the normal operation of the tappet.

[0003] Chinese patent CN203603992U discloses a valve tappet, including a valve tappet body, a cylindrical hole disposed in the valve tappet body, and an oil guide hole and an oil return hole respectively communicating with the valve tappet body. The lower end of the cylindrical hole is provided with a conical surface, a first spherical surface and a second spherical surface from top to bottom, and the diameter of the second spherical surface is smaller than the diameter of the first spherical surface.

[0004] Cleaning the valve tappet oil holes can reduce the impact of carbon buildup on engine performance. Carbon buildup can restrict valve opening, thus affecting intake air volume. Cleaning the oil holes ensures smooth valve operation and avoids power loss caused by carbon buildup. However, existing ultrasonic cleaning devices are not very effective at cleaning valve tappets because the oil holes are small and difficult to clean.

[0005] The valve tappet cleaning equipment described in authorization announcement number CN111545521B, applied in the technical field of valve tappet processing, includes an ultrasonic cleaner and a base frame for supporting the ultrasonic cleaner. The base frame is equipped with a guide roller assembly, and a circular belt is connected to the guide roller assembly. The belt has several holders for placing the valve tappets. The guide roller assembly is driven to rotate by a drive component. The ultrasonic cleaner is located inside the belt, and a section of the belt on the ultrasonic cleaner passes through a cleaning tank. The cleaning tank of the ultrasonic cleaner is equipped with a limiting component for pressing down the belt. The base frame has a loading component at the input end of the belt for conveying the valve tappets to the holders. This invention effectively reduces the cleaning workload for operators.

[0006] However, existing technologies still have shortcomings: In the existing technology, valve tappets fall one by one into the tray. With the continuous transmission of the belt, the valve tappets are conveyed into the cleaning tank for ultrasonic cleaning. However, when the valve tappets are placed in the tray, their surface and oil holes are not easy to clean properly, resulting in poor cleaning effect.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

A driven sprocket is fixedly sleeved at one end of the connecting shaft inserted into the inside of the waterproof box. A gear two is fixedly sleeved at the other end of the connecting shaft. The gear two meshes with one side of the gear one.

[0014] As an improvement, a motor is fixedly connected to one side of the upper end of the ultrasonic cleaner, and a bracket is fixedly connected to one side of the upper end of the cleaning tank. The output shaft of one end of the motor passes through the bracket and is fixedly sleeved with a drive sprocket. A chain is sleeved between the drive sprocket and the driven sprocket, and the drive sprocket and the driven sprocket are respectively meshed with the chain. Protective covers are provided on the upper ends of the motor and the drive sprocket.

[0015] As an improvement, a drain pipe is fixedly inserted into one side of the lower end of the cleaning tank. One end of the drain pipe passes through the ultrasonic cleaner and is fixedly connected to a solenoid valve. A flexible hose is fixedly sleeved on one side of the quick-release female connector. A water pump and a filter box are fixedly connected to one side of the ultrasonic cleaner. A connecting pipe is fixedly inserted between the lower end of the water pump and the upper end of the filter box. A water suction pipe is inserted into the lower end of the filter box. The lower end of the water suction pipe passes through the ultrasonic cleaner and is inserted into the cleaning tank. A water outlet pipe is fixedly inserted into the upper end of the water pump. One end of the water outlet pipe passes through the ultrasonic cleaner and is inserted into the upper side of one side of the cleaning tank. One end of the flexible hose is fixedly sleeved onto one end of the water outlet pipe.

[0016] As an improvement, a pin seat is fixedly connected to one side of the upper end of the net cover, and a pin is slidably connected to the middle of the pin seat. A buckle that works with the pin is fixedly connected to the net basket. One end of the pin is inserted into the buckle, and the buckle passes through the net cover. Slider blocks are fixedly connected to both sides of the pin. Slide grooves that work with the sliders are provided on both sides of the pin seat. A spring is fixedly connected between the slider and the slide groove.

[0017] A cleaning method for a valve lifter cleaning device includes the following steps: S1. First, place the valve lifters that need to be cleaned into the basket. When placing them, push the pin backward to disengage from the clip, and then rotate the cover upward to open it. Then, place the valve lifters with the opening facing down into the placement slots on the limiting mesh plate one by one. After placing them, close the mesh cover and re-insert the pin into the clip. Then, place the valve lifters that need to be cleaned into the limiting mesh plate in the basket one by one. S2. After the valve lifters are placed, lift the handle to place the basket into the cleaning tank 2. When placing, engage the first gear on one side of the basket with the second gear on the other side. Connect the hexagonal head at one end of the quick-release male to the middle of the positioning bracket. At the same time, connect the first and second bearings on both sides to the upper end of the support seats on both sides to complete the placement. S3. Attach the quick-release female head to the quick-release male head, add clean water and cleaning agent into the ultrasonic cleaner, and cover the water baffle after adding. S4. Press the start button on the control panel to start the ultrasonic cleaner, and press the start button on the motor to start the motor. The motor drives the drive sprocket to rotate, which in turn drives the chain to move and transmit power to the driven sprocket. The driven sprocket rotates and drives gear two to rotate, which in turn drives gear one to rotate, thereby rotating the mesh basket. S5. Start the water pump and draw water from the bottom of the water cleaning tank through the water suction pipe, filter box, and connecting pipe. Then, through the water outlet pipe, quick-release female connector, quick-release male connector, swivel joint, and pipe, the water is finally sprayed into the valve tappet through the spray nozzle. The strong water flow impacts the valve tappet and then rushes out from the oil hole of the valve tappet, which can better flush the oil hole.

[0018] S6. After cleaning, press the stop button on the control panel, turn off the motor and water pump, open the baffle, remove the quick-release female head, pull out the mesh basket by lifting the handle, and then remove the valve lifter after cleaning by removing the mesh cover. Then, rinse with clean water and dry.

[0019] The advantages of this invention compared to existing technologies are as follows: In this invention, a limiting mesh plate is set between adjacent mesh partitions in the basket, and several evenly distributed placement slots are opened at the upper end of the limiting mesh plate. Valve tappets are inserted into the placement slots, with their lower ends abutting against the mesh partition. Several evenly distributed nozzles, designed to work with the valve tappets, are evenly inserted into the side of the pipe. The nozzles are inserted inside the valve tappets, with the lower end contacting the mesh partition and the upper end contacting the mesh cover during cleaning. The stainless steel coating protects the valve tappets, and the tappets can only slide short distances up and down within the placement slots on the limiting mesh plate, preventing them from detaching. The water sprayed from the nozzles flows into the valve tappets, and the strong water flow impacts the inside of the tappets before exiting through the oil holes, providing better flushing of the oil holes. Therefore, each valve tappet can be cleaned more precisely. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] A valve lifter cleaning device, such as Figure 1 and 2 As shown, the ultrasonic cleaner 1 is equipped with lockable casters at the lower end of the ultrasonic cleaner 1 for easy movement during actual use. A cleaning tank 2 is fixedly connected to the upper part of the ultrasonic cleaner 1. An ultrasonic generator 3 is installed at the bottom inside the ultrasonic cleaner 1. A cover plate with a heat dissipation filter is installed at the front end of the ultrasonic generator 3 to facilitate maintenance of the ultrasonic generator 3.

[0039] The bottom of the cleaning tank 2 is equipped with several evenly distributed transducers 4. The ultrasonic generator 3 generates a specific frequency electrical signal through a signal generator, which is converted into a high-frequency AC signal. The transducers 4 convert the high-frequency electrical signal into high-frequency mechanical vibration above 20kHz. When the ultrasonic waves propagate in the cleaning fluid, alternating high-pressure and low-pressure zones are generated. Vacuum bubbles (cavitation nuclei) are formed in the low-pressure zone. By utilizing the cavitation, acceleration, and direct flow effects of the ultrasonic waves in the liquid, the liquid and contaminants are directly and indirectly acted upon, causing the contaminant layer to be dispersed, emulsified, and peeled off, thus achieving the cleaning purpose. This allows for better cleaning of valve lifters.

[0040] like Figure 3-5As shown, a mesh basket 5 is installed inside the cleaning tank 2, and support seats 36 are provided on both sides of the mesh basket 5. The lower end of the support seats 36 is fixedly connected to the lower end of the inside of the cleaning tank 2. The mesh basket 5 includes a rotating shaft 51, which is fixedly inserted into the middle of one side of the mesh basket 5. A bearing 52 is fixedly sleeved at one end of the rotating shaft 51 near the mesh basket 5, and a gear 53 is fixedly sleeved at the other end of the rotating shaft 51.

[0047] A drain pipe 22 is fixedly inserted into one side of the lower end of the cleaning tank 2. One end of the drain pipe 22 passes through the ultrasonic cleaner 1 and is fixedly connected to a solenoid valve 23. A flexible hose 24 is fixedly sleeved on one side of the quick-release female connector 10. A water pump 25 and a filter box 35 are fixedly connected to one side of the ultrasonic cleaner 1. A connecting pipe 26 is fixedly inserted between the lower end of the water pump 25 and the upper end of the filter box 35. A water suction pipe 27 is inserted into the lower end of the filter box 35. The lower end of the water suction pipe 27 passes through the ultrasonic cleaner 1 and is inserted into the cleaning tank 2. A water outlet pipe 37 is fixedly inserted into the upper end of the water pump 25. One end of the water outlet pipe 37 passes through the ultrasonic cleaner 1 and is inserted into the upper side of the cleaning tank 2.

[0049] A cleaning method for a valve lifter cleaning device includes the following steps: S1. First, place the valve lifters 6 that need to be cleaned into the basket 5. When placing them, push the pin 29 backward to disengage it from the buckle 30. Then, rotate the cover 57 upward to open it. Next, place the valve lifters 6 with the opening facing down into the placement slots 59 on the limiting mesh plate 58. After placing them, close the cover 57 and re-insert the pin 29 into the buckle 30. Then, place the valve lifters 6 that need to be cleaned into the limiting mesh plate 58 in the basket 5. S2. After the valve lifter 6 is placed, lift the handle 39 to place the basket 5 into the cleaning tank 2. When placing, engage the gear 1 53 on one side of the basket 5 with the gear 2 17 on the other side. Connect the hexagonal head 11 at one end of the quick release male head 9 to the middle of the positioning bracket 12. At the same time, the bearing 1 52 and bearing 2 55 on both sides are respectively connected to the upper end of the support seat 36 on both sides to complete the placement. S3. Attach the quick-release female connector 10 to the quick-release male connector 9 to complete the connection between the water pipes. Then add clean water and cleaning agent into the ultrasonic cleaner 1. After adding, cover the baffle plate 33. S4. Press the start button on the control panel 34 to start the ultrasonic cleaner 1. Press the start button on the motor 18 to start the motor 18.

When the basket 5 rotates, the pipe 54 rotates with it. The quick-release male connector 9 is fixed in position on the positioning bracket 12. The pipe 54 and the quick-release male connector 9 can rotate relative to each other through the swivel joint 8. The pipe 54 rotates on one side of the quick-release male connector 9 through the swivel joint 8, so as not to affect the quick-release female connector 10 and other pipes connected to it. S5. Start the water pump 25, and draw water from the bottom of the water cleaning tank 2 through the water suction pipe 27, filter box 35, and connecting pipe 26. Then, through the water outlet pipe 37, hose 24, quick-release female connector 10, quick-release male connector 9, swivel joint 8, and pipe 54, the water is finally sprayed into the valve lifter 6 through the spray pipe 7. The strong water flow impacts the valve lifter 6 and then rushes out from the oil hole of the valve lifter 6, which can better flush the oil hole; and the valve lifter 6 is cleaned in the cleaning tank 2 of the ultrasonic cleaner 1.

[0050] S6. After cleaning, press the stop button on the control panel 34, turn off the motor 18 and water pump 25, open the baffle 33, remove the quick-release female head 10, pull out the mesh basket 5 through the lifting handle 39, and then remove the valve lifter 6 after cleaning through the mesh cover 57 for subsequent rinsing with clean water and drying.
