Description

Technical Field

[0001] This utility model relates to the technical field of piston ring cleaning devices, and in particular to a cleaning device suitable for piston rings. Background Technology

[0002] Currently, aluminum pistons with inserts are widely used in numerous industrial sectors, particularly in the automotive, aerospace, marine propulsion, and heavy machinery industries, due to their excellent thermal conductivity, lightweight characteristics, and good wear resistance. The inserts in these pistons, as key components enhancing piston strength and wear resistance, directly affect the reliability and durability of the entire piston and even the entire engine system. Therefore, performing a series of precise and meticulous surface treatments, especially cleaning, on the inserts before casting is of paramount importance.

[0003] Cleaning, a crucial step in the pretreatment of the ring insert, aims to thoroughly remove grease, dirt, oxides, and other impurities from the ring insert surface that may affect casting quality and the bonding between the insert and the aluminum alloy body. This step not only helps improve the surface quality of the insert and ensures a good bond with the aluminum alloy body, but also effectively reduces defects that may occur during the casting process, such as porosity and inclusions, thereby improving the overall performance and reliability of the final product.

[0004] However, when faced with the production needs of small-batch ring setting, continuing to use the cleaning methods employed in mass production becomes less efficient and economical. In large-scale production, due to the uniform product specifications and large quantities, cleaning can be carried out using highly automated and standardized processes, utilizing large cleaning equipment and efficient cleaning agents to achieve efficient cleaning results at a relatively low cost. However, in the production of small-batch rings, due to the small order volume and diverse varieties, continuing to use this cleaning method from mass production exposes problems such as operational difficulty, time cycle, and cost control.

[0021] Multiple hanging rods 4 are fixedly installed at the lower end of the lower end cover 24. The multiple hanging rods 4 are evenly distributed in a circumferential shape, and multiple clamping clips 5 are evenly spaced from top to bottom on the hanging rods 4. In the optimized solution, the number of hanging rods 4 is [number missing].

[0022] The cavity of the cleaning tank 2 is equipped with a circulation mechanism, which includes an inner circulation cylinder 6, a primary circulation pipe 17, a secondary circulation pipe 19, a filter support 20, and filter cotton 21. A partition plate 8 is installed at the lower end of the cavity of the cleaning tank 2, which divides the cavity into an upper cavity 7 and a lower cavity 9. The partition plate 8 has multiple through holes that connect the upper cavity 7 and the lower cavity 9. An inlet pipe 11 and an outlet pipe 15 are fixedly installed at the lower end of the cleaning tank 2. The inlet pipe 11 and the outlet pipe 15 are connected to the lower cavity 9. The lower end of the inlet pipe 11 is connected to the first valve 12 and the first liquid pump 13 in sequence, and the lower end of the outlet pipe 15 is connected to the second valve 16.

[0023] A circulating inner cylinder 6 is fixedly installed in the upper cavity 7 of the cleaning tank 2. The lower end of the circulating inner cylinder 6 is fixedly connected to the partition plate 8. The circulating inner cylinder 6 has a primary circulation hole, and a second liquid pump 18 is installed in the primary circulation hole. The lower end of the primary circulation hole is connected to the lower cavity 9 of the cleaning tank 2. The outer wall of the circulating inner cylinder 6 has multiple secondary circulation holes. The upper end of the secondary circulation hole is connected to the upper end of the primary circulation hole. The lower end of the secondary circulation hole is open and is flush with the position of the clamping clamp 5 at the uppermost end of the hanging rod 44.

[0024] A filter bracket 20 is installed at the upper end of the primary circulation hole of the inner circulation cylinder 6. Filter cotton 21 is installed inside the filter bracket 20, and the filter cotton 21 is installed at the connection between the primary and secondary circulation holes. A sealing cover plate 22 is installed at the upper end of the filter bracket 20. In the optimized solution, the filter cotton 21 is made of polyester fiber (PET), polypropylene fiber (PP), etc., to effectively protect the liquid pump from damage by impurities during use.

[0025] The bottom of the cleaning tub 2 is equipped with multiple bases 10, and the inside of the side wall of the cleaning tub 2 is provided with heating holes, and heating rods 3 are installed inside the heating holes; an ultrasonic vibrator 14 is installed on the bottom wall of the cleaning tub 2.

[0026] The operating procedure is as follows: Step 1: Clean the cleaning tank 2, connect the inlet pipe 11 to deionized water, open the first valve 12 and the first liquid pump 13 to pump the deionized water into the cleaning device. When the water level is higher than the lower opening of the secondary circulation pipe 19, close the first valve 12 and the first liquid pump 13, and open the second liquid pump 18 to clean the deionized water inside the cleaning device and the circulation pipe for 20-30 minutes. Close the inlet pipe 11 and the first valve 12, and open the second valve 16 to discharge the deionized water from the cleaning device. After the deionized water in the cleaning device has been completely discharged, close the second liquid pump 18 and the second valve 16. Periodically open the sealing cover 22, check and replace the filter cotton 21, and install the clean filter cotton 21 inside the filter support 20.

[0027] Step 2: Install and fix the workpiece. Use clamping clamp 5 to clamp the ring-shaped workpiece. The same ring-shaped workpiece is fixed by clamping clamp 5 of the same height on the hanging rod 4. Similarly, install all the ring-shaped workpieces from top to bottom.

[0028] Step 3: Cleaning preparation. Place the ring clamping device containing the workpiece inside the cleaning tank 2. Connect the cleaning fluid to the inlet pipe 11. Open the first valve 12 and the first pump 13 to pump the cleaning fluid into the cleaning tank 2. When the cleaning fluid level is 10-15mm higher than the lower opening of the secondary circulation pipe 19, close the first valve 12 and the first pump 13, and turn on the second pump 18 to circulate the cleaning fluid inside the cleaning tank 2 and the circulation pipe. Simultaneously, turn on the heating rod 3 and the ultrasonic vibrator 14 to degrease and ultrasonically clean the ring workpiece, increasing... The purpose of heating is to increase the temperature of the cleaning solution, making the decontamination process more rapid. The purpose of ultrasonic vibration is to accelerate the removal of impurities from the workpiece surface. Depending on the actual situation, multiple cleanings can be performed. The first and third steps can be repeated to clean the inside of the cleaning tank 2 and then the cleaning solution can be replaced to achieve multiple cleanings. At the same time, by adding an active agent inside the cleaning tank 2, an active coating is generated through a chemical reaction, which enhances the bonding performance between the coating and the aluminum alloy body at the casting interface during the casting process, and preferentially avoids the generation of interface casting defects caused by the difference in physicochemical properties between the inlay ring and the aluminum alloy body.

[0029] Step 4: Remove surface residue. After cleaning, open the second valve 16 to drain the cleaning solution in the cleaning tank 2. After the cleaning solution in the cleaning tank 2 has been drained, turn off the second liquid pump 18, the second valve 16, the heating rod 3 and the ultrasonic vibrator 14. Repeat the first step and take out the insert clamping fixture and remove the cleaned insert. Use a compressed air gun to dry the surface moisture of the insert.

[0030] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
