Description

Technical Field

[0001] This invention relates to the field of engine cylinder head processing technology, specifically to an all-around cleaning device for engine cylinder heads. Background Technology

[0002] With the rapid development of the automotive industry, the engine, as the core component of a car, directly affects the overall performance and service life of the car in terms of its performance and cleanliness. The engine cylinder head, as a key component of the engine, has a complex internal structure that makes cleaning particularly important. Traditional engine cylinder head cleaning methods are mostly manual, which is not only inefficient but also makes it difficult to guarantee the cleaning effect. In particular, it is difficult to thoroughly clean the dead corners and complex structures inside the cylinder head.

[0003] While some engine cylinder head cleaning equipment exists on the market, these devices are inconvenient for automatically positioning and fixing the cylinder head during the cleaning process. Manual handling is still required for positioning, which adds considerable trouble to the cleaning work and reduces the cleaning effect. Furthermore, during water spray cleaning, the high-pressure water jets impact the surface of the cylinder head, causing a large amount of water to bounce and splash out. This splashed water adheres to the inner wall of the protective shell and flows down, making it difficult to utilize the splashed water and resulting in water waste. Summary of the Invention

[0004] The purpose of this invention is to provide an all-around cleaning device for engine cylinder heads to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an all-around cleaning device for engine cylinder heads, comprising a cleaning box, a conveyor frame, a tray, a clamping mechanism, a water spraying mechanism, and a vibration mechanism. A conveyor roller is rotatably mounted on the inner side of the conveyor frame, and a tray is placed on the top of the conveyor roller. Positioning grooves are provided on both sides of the tray. A cleaning box is fixedly mounted on the top of the conveyor frame. A clamping mechanism is rotatably mounted inside the cleaning box. The clamping mechanism includes a rotating frame, a double-headed cylinder, a first positioning clamp, a straightening seat, a guide wheel, a sliding frame, and a second positioning clamp. The rotating frame is rotatably connected to the cleaning box. The first positioning clamp is slidably mounted on the outer side of the rotating frame. A double-headed cylinder connects the rotating frame and the first positioning clamp. A straightening seat is fixedly mounted on the inner wall of the rotating frame. A guide wheel is rotatably mounted on the bottom of the straightening seat. The straightening seat is connected to the positioning groove. A sliding frame is slidably mounted between the rotating frames. A second positioning clamp is fixedly mounted on the bottom of the sliding frame.

[0006] A water spraying mechanism and a vibration mechanism are fixedly installed inside the cleaning tank outside the clamping mechanism. The water spraying mechanism and the vibration mechanism are arranged adjacent to each other. The vibration mechanism includes a mounting frame, a rebound plate, a vibration spring, and a movable rod. The mounting frame is fixedly installed between the mounting frame and the cleaning tank. The bottom of the mounting frame is movably connected to the rebound plate through the movable rod. A vibration spring is fixedly connected between the rebound plate and the mounting frame.

[0007] Preferably, a compensation mechanism is fixedly installed at the bottom of the conveyor frame. The compensation mechanism includes a fixed frame, a movable seat, a movable groove, and a thrust spring. The fixed frame is fixedly installed with the conveyor frame, and the movable seat is slidably installed on the top of the fixed frame through the movable groove. A thrust spring is fixedly connected between the movable seat and the fixed frame.

[0008] Preferably, a lifting mechanism is fixedly installed on the top of the movable seat. The lifting mechanism includes a drive rod, a lifting frame, and a positioning stake. The drive rod is fixedly installed between the movable seat and the drive rod. The output end of the drive rod is fixedly connected to the lifting frame. A positioning stake is fixedly installed on the top of the lifting frame. A positioning hole is provided at the bottom of the pallet. The positioning hole is connected to the positioning stake.

[0009] Preferably, the water spraying mechanism includes a water spray pipe, a water spray head, and a connecting pipe. The water spray pipe is fixedly connected to the cleaning tank. The water spray head is fixedly installed at the bottom of the water spray pipe, and the connecting pipe is fixedly installed at the top of the water spray pipe, with the connecting pipe extending out of the cleaning tank.

[0010] Preferably, the clamping mechanism further includes a sliding column and a tension spring. The sliding column is fixedly installed between the correction seat and the rotating frame. The sliding column is fixedly connected to the sliding frame. A tension spring is sleeved on the outside of the sliding column. The two ends of the tension spring are fixedly connected to the sliding frame and the correction seat, respectively.

[0011] Preferably, a support frame is fixedly installed at the bottom of the conveyor frame, a water receiving box is fixedly installed on the inner side of the support frame, and a drain pipe is fixedly installed at the bottom of the water receiving box.

[0012] Preferably, a motor is fixedly installed at the rear end of the cleaning tank, and the motor is connected to the rotating frame via a belt drive.

[0013] Preferably, the surface of the rebound plate is provided with protrusions, and the protrusions are arranged in an equally spaced matrix. The surfaces of the first positioning clamp and the second positioning clamp are both provided with positioning protrusions.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention, through the cooperation of a lifting mechanism and a clamping mechanism, enables the cylinder head to be placed on a pallet for positioning. The lifting mechanism then lifts the pallet, raising the cylinder head into the clamping mechanism. Guide wheels, inclined at the bottom of the positioning seat, are inserted into the positioning groove, correcting the position of the pallet and automatically centering the cylinder head. The top limiting hole of the cylinder head aligns with the second positioning clamp, allowing it to fit snugly against the top of the cylinder head. The clamping action of the first positioning clamp provides positioning and clamping for both sides of the cylinder head. This multi-directional clamping effect facilitates automatic loading, positioning, and fixing of the cylinder head, preventing it from falling during rotation and cleaning. It eliminates the need for manual loading and unloading, improving work efficiency.

[0016] 2. This invention, by incorporating a vibration mechanism, enables the cylinder head to be cleaned by high-pressure water spray. The large amount of water splashed out impacts the rebound plate, causing it to vibrate. This vibration forcefully ejects the water droplets, which fall in a rain-like pattern, effectively rinsing the cylinder head and comprehensively covering the cleaning area. This significantly improves the cleaning effect and also effectively utilizes the splashed water, preventing water waste.

[0017] 3. By incorporating a compensation mechanism, this invention allows the movable frame to move along the fixed frame when the pallet is lifted into the clamping mechanism. This is achieved through the limiting effect of the straightening seat on the positioning groove, compensating for the lateral movement of the pallet. This ensures that the positioning groove accurately engages with the straightening seat, enabling precise positioning of the cylinder head. This avoids situations where the pallet is not moved to the correct position, preventing the cylinder head from being properly positioned and clamped by the clamping mechanism. This effectively improves positioning accuracy and facilitates the elimination of positioning errors. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 8This invention provides a technical solution: an all-around cleaning device for engine cylinder heads, comprising a cleaning tank 1, a conveyor frame 2, a tray 4, a clamping mechanism 7, a water spraying mechanism 8, and a vibration mechanism 9. A conveyor roller 203 is rotatably mounted on the inner side of the conveyor frame 2, and a tray 4 is placed on top of the conveyor roller 203. Positioning grooves 401 are provided on both sides of the tray 4. The cleaning tank 1 is fixedly mounted on top of the conveyor frame 2. A clamping mechanism 7 is rotatably mounted inside the cleaning tank 1. The clamping mechanism 7 includes a rotating frame 701, a double-headed cylinder 702, a first positioning clamp 703, a straightening seat 704, a guide wheel 705, a sliding frame 707, and a second positioning clamp 708. The rotating frame 701 is rotatably connected to the cleaning tank 1, and the first positioning clamp 708 is slidably mounted on the outer side of the rotating frame 701. 03. A double-headed cylinder 702 is connected between the rotating frame 701 and the first positioning clamp 703. A straightening seat 704 is fixedly installed on the inner wall of the rotating frame 701. A guide wheel 705 is rotatably installed on the bottom of the straightening seat 704. The straightening seat 704 is connected to the positioning groove 401. A sliding frame 707 is slidably installed between the rotating frames 701. A second positioning clamp 708 is fixedly installed on the bottom of the sliding frame 707. The clamping mechanism 7 also includes a sliding column 706 and a tension spring 709. A sliding column 706 is fixedly installed between the straightening seat 704 and the rotating frame 701. The sliding column 706 is fixedly connected to the sliding frame 707. A tension spring 709 is sleeved on the outside of the sliding column 706. The two ends of the tension spring 709 are fixedly connected to the sliding frame 707 and the straightening seat 704, respectively.

[0029] A water spraying mechanism 8 and a vibration mechanism 9 are fixedly installed in the cleaning tank 1 outside the clamping mechanism 7. The water spraying mechanism 8 and the vibration mechanism 9 are arranged adjacent to each other. The vibration mechanism 9 includes a mounting frame 901, a rebound plate 902, a vibration spring 903 and a movable rod 904. The mounting frame 901 is fixedly installed between the mounting frame 901 and the cleaning tank 1. The bottom of the mounting frame 901 is movably connected to the rebound plate 902 through the movable rod 904. The vibration spring 903 is fixedly connected between the rebound plate 902 and the mounting frame 901.

[0030] Specifically, by placing the pallet 4 on the conveyor roller 203, the pallet 4 can be easily conveyed using the conveyor roller 203. The top of the pallet 4 is provided with a limiting protrusion, which can be positioned according to the limiting hole position at the bottom of the cylinder head. When the cylinder head is placed on the pallet 4, the limiting protrusion can be inserted into the corresponding limiting hole at the bottom of the cylinder head to limit the cylinder head and prevent displacement or detachment. By conveying the pallet 4 into the cleaning tank 1, the pallet 4 can correspond to the clamping mechanism 7. By lifting the pallet 4 upwards, the pallet 4 can move to the inside of the clamping mechanism 7. When the pallet 4 moves upwards, the straightening seat 704 can be inserted into the positioning groove 401. Due to the conical bottom of the straightening seat 704, and with the rolling action of the guide wheel 705, the positioning groove 401 can smoothly engage with the straightening seat 704, correcting the position of the pallet 4 and ensuring that the cylinder head accurately corresponds to the second positioning clamp 708. By making the top of the cylinder head fit against the second positioning clamp 708, and continuing to lift the cylinder head, the sliding frame 707 can be pushed to slide upward along the sliding column 706, which can stretch the tension spring 709. When the cylinder head is lifted to a certain distance, the positions of the limiting holes on both sides of the cylinder head can be aligned with the first positioning clamp 703. By the pistons at both ends of the double-headed cylinder 702 contracting, the first positioning clamp 703 can be driven to close and clamp the two sides of the cylinder head. It can be separated from the cylinder head by driving the support plate 4 to move downward. Through the tension of the tension spring 709, the second positioning clamp 708 can be provided with a downward thrust, so that the second positioning clamp 708 can tightly clamp the top of the cylinder head. Together with the clamping of the two sides of the cylinder head by the first positioning clamp 703, a triangular clamping effect can be formed, which can firmly fix the cylinder head and prevent the cylinder head from falling off. It can conveniently perform automatic feeding, positioning, clamping and fixing of the cylinder head without manual loading and unloading operations, thus improving work efficiency.

[0031] By rotating the rotating frame 701, the cylinder head can be rotated synchronously. The water spray mechanism 8 can be used to easily perform all-round washing of the cylinder head. When the water spray mechanism 8 uses high-pressure water to wash the cylinder head, the splashed water can hit the rebound plate 902, which can compress the vibration spring 903. Through the elastic action of the vibration spring 903, the rebound plate 902 can generate a vibration effect. The flipping action of the movable rod 904 can make the rebound plate 902 move up and down without easily flipping. Through the vibration action of the rebound plate 902, the water can be strongly rebounded and ejected, so that the water droplets fall in a rain-like pattern, which can rinse the cylinder head and cover the cleaning area of ​​the cylinder head more comprehensively, improving the cleaning effect of the cylinder head. At the same time, the splashed water can be effectively utilized to avoid water waste.

[0032] Furthermore, such as Figure 4 As shown, a compensation mechanism 3 is fixedly installed at the bottom of the conveyor frame 2. The compensation mechanism 3 includes a fixed frame 301, a movable seat 302, a movable groove 303, and a thrust spring 304. The fixed frame 301 is fixedly installed with the conveyor frame 2. The movable seat 302 is slidably installed on the top of the fixed frame 301 through the movable groove 303. The thrust spring 304 is fixedly connected between the movable seat 302 and the fixed frame 301.

[0033] Specifically, when the lifting plate 4 engages with the straightening seat 704, the moving seat 302 can move along the moving groove 303, allowing the plate 4 to move left and right as a whole. This allows the positioning groove 401 to engage with the straightening seat 704, compensating for the displacement of the plate 4 and correcting its offset position. This ensures that the cylinder head can be accurately positioned between itself and the clamping mechanism 7.

[0034] Furthermore, such as Figure 4 As shown, a lifting mechanism 6 is fixedly installed on the top of the movable seat 302. The lifting mechanism 6 includes a drive rod 601, a lifting frame 602 and a positioning stake 603. The drive rod 601 is fixedly installed between the movable seat 302 and the output end of the drive rod 601 is fixedly connected to the lifting frame 602. The positioning stake 603 is fixedly installed on the top of the lifting frame 602. A positioning hole 402 is opened at the bottom of the support plate 4. The positioning hole 402 is connected to the positioning stake 603.

[0035] Specifically, the drive rod 601 can be a hydraulic push rod or an electric push rod as the driving force. The extension and retraction of the drive rod 601 can drive the lifting frame 602 to move up and down. When the drive rod 601 extends upward, it can push the lifting frame 602 upward, so that the positioning stake 603 can be inserted into the positioning hole 402 at the bottom of the pallet 4, so that the lifting frame 602 can be engaged and positioned with the pallet 4, which can prevent the pallet 4 from falling off the lifting frame 602. The lifting frame 602 can push the pallet 4 upward, which can lift the cylinder head into the clamping mechanism 7 for clamping and fixing. At the same time, the clamping mechanism 7 releases the clamping effect on the cylinder head, so that the pallet 4 can lift the cylinder head again. When the lifting frame 602 moves downward, it can easily lift the cylinder head out of the clamping mechanism 7, which facilitates automatic unloading operation.

[0036] Furthermore, such as Figure 5 and Figure 7 As shown, the water spraying mechanism 8 includes a water spray pipe 801, a water spray head 802, and a connecting pipe 803. The water spray pipe 801 is fixedly connected to the cleaning tank 1. The water spray head 802 is fixedly installed at the bottom of the water spray pipe 801, and the connecting pipe 803 is fixedly installed at the top of the water spray pipe 801. The connecting pipe 803 extends out of the cleaning tank 1.

[0037] Specifically, the connecting pipe 803 allows for easy connection to an external water source, which can then be transported to the spray pipe 801. The spray pipe 801 has multiple sets of components that are interconnected. The spray nozzles 802 at the bottom of the two spray pipes 801 are angled, allowing for the cleaning of the cylinder head's blind spots during rotation, thus reducing blind spots.

[0038] Furthermore, such as Figure 2 As shown, a support frame 201 is fixedly installed at the bottom of the conveyor frame 2, a water receiving box 202 is fixedly installed on the inner side of the support frame 201, and a drain pipe 204 is fixedly installed at the bottom of the water receiving box 202.

[0039] Specifically, the support frame 201 can easily support the equipment, the water collection box 202 can collect the wastewater generated during the rinsing process, and the drain pipe 204 can discharge the wastewater in the water collection box 202.

[0040] Furthermore, such as Figure 2 As shown, a motor 5 is fixedly installed at the rear end of the cleaning tank 1, and the motor 5 is connected to the rotating frame 701 by a belt 501.

[0041] Specifically, by connecting the output end of the motor 5 to the rotating shaft on the rotating frame 701 via the belt 501, the motor 5 can be started to drive the rotating frame 701 to rotate via the belt 501, which can make the entire clamping mechanism 7 rotate and drive the cylinder head to perform a rotating flushing operation.

[0042] Furthermore, such as Figure 7 and Figure 8 As shown, the surface of the rebound plate 902 is provided with protrusions, and the protrusions are arranged in an equally spaced matrix. The surfaces of the first positioning clamp 703 and the second positioning clamp 708 are both provided with positioning protrusions.

[0043] Specifically, when the water splash is bounced by the rebound plate 902, the protrusions on the rebound plate 902 can decompose the water splash, so that the water splash can be evenly dispersed and the reflected water splash can fall in the form of raindrops. By setting corresponding positioning protrusions on the first positioning clamp 703 and the second positioning clamp 708 according to the position of the limiting hole on the cylinder head, when the first positioning clamp 703 and the second positioning clamp 708 clamp the cylinder head, the positioning protrusions can be inserted into the limiting hole on the surface of the cylinder head for limiting, which can prevent the cylinder head from falling off.

[0044] Working principle and usage process of this invention:

[0045] First, by placing the pallet 4 on the conveyor roller 203, the cylinder head is placed on the pallet 4 for positioning. The cylinder head is then transported to the cleaning box 1 by the conveyor roller 203. At the same time, the pallet 4 is aligned with the lifting mechanism 6. The drive rod 601 extends and drives the lifting frame 602 to move upward, so that the positioning pin 603 is inserted into the positioning hole 402. This can limit the position between the lifting frame 602 and the pallet 4, preventing the pallet 4 from falling off the lifting frame 602.

[0046] Then, by lifting the support plate 4 upward, the cylinder head is lifted into the clamping mechanism 7, so that the straightening seat 704 is inserted into the positioning groove 401. Through the limiting effect of the straightening seat 704 and the positioning groove 401, the moving seat 302 can move horizontally left and right along the moving groove 303, so that the positioning groove 401 can engage with the straightening seat 704. This makes it easy to compensate and correct the offset position of the support plate 4, so that the cylinder head can be accurately positioned with the second positioning clamp 708.

[0047] Secondly, by lifting the cylinder head to contact the second positioning clamp 708, the sliding frame 707 is driven to slide upward, so that the first positioning clamp 703 can correspond to the two sides of the cylinder head. The double-headed cylinder 702 drives the first positioning clamp 703 to close, which can clamp and fix the two sides of the cylinder head. The tension spring 709 provides a downward pushing force to the second positioning clamp 708, which can clamp the top of the cylinder head. Together with the first positioning clamp 703, the cylinder head can be clamped at three points to prevent the cylinder head from falling off. After clamping, the lifting mechanism 6 drives the support plate 4 to descend, so that the support plate 4 is separated from the cylinder head.

[0048] Finally, by starting the motor 5, the belt 501 drives the rotating frame 701 to rotate, which in turn rotates the cylinder head 360°. The cleaning agent is then delivered into the water spray pipe 801, and the water spray head 802 cleans the cylinder head from all angles. The resulting water splashes onto the rebound plate 902, striking it. The vibration spring 903 causes the rebound plate 902 to vibrate, and the resulting amplitude deflects the water splashes, dispersing them into raindrops. It can easily rinse the cylinder head, effectively improving the cleaning efficiency. After cleaning, the rotating frame 701 stops rotating, and the lifting mechanism 6 lifts the pallet 4 to lift the cylinder head again, so that the first positioning clamp 703 releases the clamping effect on the cylinder head. The lifting mechanism 6 drives the pallet 4 to move downward, which can simultaneously drive the cylinder head to move downward and separate from the clamping mechanism 7. The pallet 4 moves downward and contacts the conveying roller 203. The conveying roller 203 transports the pallet 4 out of the cleaning box 1, making it convenient to remove the cleaned cylinder head.
