Description

Technical Field

[0001] The invention relates to the technical field of cylinder liner cleaning, and in particular to a cylinder liner cleaning device for electric pump processing. Background Art

[0002] In the manufacturing process of electric pumps (especially hydraulic pumps and lubricating oil pumps), the cylinder liner is a core precision component, and its machining quality directly determines the pump's performance, efficiency, and lifespan. Cylinder liners are typically made of cast iron, steel, or alloys. After undergoing finishing processes such as turning, boring, and honing, a large amount of machining residue adheres to the inner surface of the cylinder liner. These residues primarily include metal chips and abrasive particles, coolant and lubricant residue, and environmental pollutants. Failure to thoroughly remove these residues can have serious consequences: impaired assembly accuracy, reduced product performance, shortened service life, increased premature failure rates, and disruptions to subsequent processes.

[0003] However, the current common methods for cylinder liner cleaning have significant limitations, including:

[0004] 1. Manual scrubbing / wiping is inefficient and labor-intensive.

[0005] 2. The fragmentation and inefficiency of the traditional cylinder liner cleaning process are specifically manifested as follows: In the traditional process, the cylinder liner loading, outer wall flushing, inner wall flushing, high-pressure treatment, drying and other links are mostly independent processes, which require multiple manual transfers and repeated clamping, resulting in low efficiency and easy secondary pollution.

[0006] 3. The cleaning effect is not thorough and there are dead corner problems. Specifically, when cleaning the outer wall, traditional fixtures (such as clamping the periphery) will block the cleaning area, and fixed nozzles are difficult to cover complex curved surfaces and all angles; when cleaning the inner wall, a single flush is difficult to cover the entire length of the inner wall, especially deep holes or ends are prone to residual stains; the nozzle insertion depth and angle are limited.

[0007] 4. The clamping and positioning are inflexible and lack precision. Specifically, the traditional cleaning equipment has a single function and is difficult to adapt to the needs of different cleaning steps (such as clamping the end face or clamping the peripheral surface); the positioning accuracy is poor, affecting the cleaning effect (especially the inner wall, high-pressure spraying) or causing damage to the workpiece.

[0008] 5. High resource consumption (water, energy) and environmental issues, specifically: the traditional cleaning process consumes a lot of clean water, the direct discharge of wastewater or simple treatment costs are high; the drying efficiency is low and the energy consumption is high.

[0009] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0039] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following aspects:

[0040] 1. Significant improvement in efficient automation and continuous operation capabilities:

[0041] The present invention adopts an integrated process design, connecting the cleaning box (multi-angle flushing), high-pressure treatment box (high-pressure spraying) and drying box (convection drying) in sequence and fixing them on the central support frame.

[0042] Combined with the continuous conveying module (including transfer rollers, square plate transfer seats, and limit clamps), the entire process of cylinder liner automatic continuous conveying from loading, outer wall flushing, inner wall flushing, high-pressure spraying to drying is realized, which significantly reduces manual intervention and transportation time.

[0043] The square plate transfer seat realizes sliding guidance through the limit groove, and its V-shaped groove ensures stable clamping of the cylinder liner.

[0044] The transfer rollers rotate synchronously to drive the square plate transfer seat to move smoothly, and the conveying motor and sprocket transmission structure provide reliable transmission power and precise position control, thereby ensuring the accurate positioning of the cylinder sleeve during the transmission process.

[0045] 2. Comprehensive and high-quality cleaning effects are achieved:

[0046] External wall cleaning: Rotating the water distributor drives the vertical flushing nozzles. Combined with the lifting and clamping mechanism (driven by the steering motor, which rotates the steering wheel and extends the telescopic block), the cylinder liner itself rotates and adjusts its position, achieving a complete and seamless external wall flushing. A flat clamping plate securely holds the cylinder liner end face, effectively preventing obstruction of the surrounding surface.

[0047] Internal wall cleaning: Insert flushing is used, and an extension water pipe with a horizontal flushing nozzle is inserted into the inner cavity of the cylinder liner to spray directly. The steering motor drives the cylinder liner upside down to switch the end face, which can perform a second internal wall flushing to completely eliminate residual dead corners.

[0048] High-pressure spraying: The U-shaped spray water pipe (with high-pressure spray head) is arranged around the cylinder liner and is driven to rotate by the second transmission motor to ensure that the high-pressure water column covers the cylinder liner surface in all directions, effectively removing stubborn stains and particles.

[0049] 3. Intelligent clamping and positioning functions are perfect:

[0050] The present invention is equipped with a multifunctional lifting and clamping mechanism with dual-mode clamping capability: it can clamp the end surface (using a flat clamping plate) or the peripheral surface (using an arc clamping plate) to meet the needs of different cleaning steps.

[0051] The lifting drive box controls the vertical screw to achieve precise adjustment of the cylinder liner height (closer to or away from the nozzle).

[0052] The steering motor provides rotational freedom and is combined with the telescopic block to achieve fine-tuning of the position, thereby achieving precise lifting and rotational positioning of the cylinder liner.

[0053] 4. Highly efficient and energy-saving drying and water circulation system:

[0054] Efficient Drying: Utilizing forced convection drying technology, dual fans deliver air in opposite directions through two longitudinally symmetrical drying ducts, generating countercurrents that accelerate moisture evaporation. Deflectors within the drying ducts optimize airflow distribution, ensuring uniform and efficient drying.

[0055] Closed-loop water circulation: Wastewater from the cleaning and high-pressure treatment tanks flows into a water collection and filtration tank for filtration and purification. The filtered water is then pumped (via the primary return pipe) to the flushing water supply tank for general cleaning. Simultaneously, a booster pump (via the secondary return pipe) supplies the spray water supply tank for high-pressure spraying. This closed-loop system significantly reduces fresh water consumption and wastewater discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0097] When the present invention is used, the operation process is as follows:

[0098] Loading and positioning: First, the electric pump cylinder sleeve to be cleaned is clamped and placed on two limit clamping plates 14. Start the conveying motor 15, control the transfer rollers 9 to rotate synchronously, drive the square plate transfer seat 13 to move horizontally, and send the cylinder sleeve into the cleaning box 2.

[0099] Preparation for outer wall flushing: Activate the lifting control module to drive the lifting partition 45 downward to separate the cleaning box 2 from the high-pressure treatment box 3. Control the telescopic block 32 to extend, so that the two flat clamping plates 34 move to both sides of the cylinder liner port, and then clamp the two ends of the cylinder liner by moving them in opposite directions.

[0100] Outer wall flushing: Start the lifting drive box 28, drive the vertical screw 29 to rotate, and drive the lifting slide 30 to move upward along the right-angle guide rail 27 as a whole, so that the cylinder liner is close to the vertical flushing nozzle 20. Start the first transmission motor 24, drive the first transmission side wheel 25 to rotate, and drive the rotating water diversion seat 19 to rotate around the axis through the first transmission belt 26 and the first center transmission wheel 23. At the same time, the clean water in the flushing water supply tank 17 enters the rotating water diversion seat 19 through the water supply pipe 18. Turn on the vertical flushing nozzle 20 to flush the circumference of the cylinder liner. During the flushing process, start the steering motor 31 to drive the side steering wheel 33 to rotate as a whole, and cooperate with the telescopic action of the telescopic block 32 to achieve flushing coverage of the entire outer surface of the cylinder liner.

[0101] Inner wall flushing preparation: After the outer wall is flushed, put the cylinder liner back. Replace the clamping plate 34 and use two arc-shaped clamping plates 34 to clamp the outer peripheral wall of the cylinder liner from the upper and lower sides.

[0102] Inner wall flushing: Repeat the lifting and lowering operation to move the cylinder liner upward and install it on the extension water pipe 21. Turn on the horizontal flushing nozzle 22 to flush and clean the inner wall of the cylinder liner. Furthermore, the steering motor 31 drives the side steering wheel 33 to rotate, reversing the upper and lower end surfaces of the cylinder liner and performing a second inner wall flushing.

[0103] High-pressure spray preparation: After rinsing, return the cylinder liner to the limiting clamp 14. Raise the lifting partition 45, and control the square plate transfer base 13 to move the cylinder liner into the high-pressure treatment box 3. Then, simultaneously control the two lifting partitions 45 to descend, isolating the high-pressure treatment box 3 from the cleaning box 2 and the drying box 4.

[0104] High-pressure spraying: The booster pump is activated, and the spray water in the spray water supply tank 36 enters the spray water pipe 38 through the transfer water pipe 37. The high-pressure spray head 39 is activated, spraying the cylinder liner with a high-pressure water column. During the spraying process, the second transmission motor 41 is activated, driving the second transmission side wheel 42 to rotate. The second transmission belt 43 and the second center transmission wheel 40 drive the spray water pipe 38 to rotate around its axis, achieving full coverage of the spraying.
