Description

Technical Field

[0001] This invention relates to the field of compressor processing technology, specifically to a surface cleaning treatment device for compressor housing processing. Background Technology

[0002] As the core load-bearing component of the compressor, the compressor housing is prone to accumulating complex contaminants such as cutting fluid residue, mineral oil, metal shavings, and rust during processing. If these contaminants are not thoroughly removed, they will seriously affect the processing quality of subsequent welding, painting, and other processes, leading to problems such as insufficient weld strength and coating peeling, thereby reducing the overall reliability and service life of the compressor.

[0003] Currently, the industry mainly uses single ultrasonic cleaning, single plasma cleaning, or simple spray cleaning for compressor housing surface cleaning equipment. However, single ultrasonic cleaning has limited ability to decompose organic oil stains, and single plasma cleaning is difficult to remove stubborn metal debris and rust. The two lack an effective synergistic mechanism, resulting in incomplete cleaning of complex contaminants and easy formation of cleaning dead zones. In addition, the clamping mechanisms of existing equipment are mostly designed with fixed specifications, which are difficult to adapt to compressor housings with different outer diameters and lengths. Moreover, there is a lack of effective pressure control and surface protection during the clamping process, which can easily cause scratches on the housing surface. The actions of functional modules such as spraying, ultrasonic, and plasma during the cleaning process lack precise linkage, and areas such as the bottom of the housing are difficult to be fully covered, resulting in poor cleaning uniformity and failing to meet the requirements of high-precision machining for housing surface cleanliness. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a surface cleaning treatment device for compressor housing processing, in order to solve the aforementioned technical defects.

A high-pressure nozzle is installed on the opposite side of each of the two swing spray frames.

[0010] Furthermore, both sides of the top of the frame are provided with sliding grooves, and both sides of the bottom of the cleaning frame are rotatably provided with sliding balls, and the surfaces of the sliding balls on both sides are slidably connected to the inside of the sliding grooves on both sides respectively; both sides of the top of the frame are fixedly provided with control servo electric cylinders, and the drive ends of the control servo electric cylinders on both sides are fixedly connected to the two sides of the cleaning frame respectively.

[0011] Furthermore, servo linear slides are fixedly installed on both sides of the lower part of the frame, and the tops of the two servo linear slides are slidably connected to the rear side of the bottom of the placement rack; the placement rack has a placement cavity inside, and fixed frames are fixedly installed on both sides inside the placement cavity. A rotary servo motor is fixedly installed on one side of each of the two fixed frames, and a rotary connecting block is fixedly installed at one end of the output shaft of each of the two rotary servo motors. A telescopic connecting rod is slidably installed inside the rotary connecting block, and a positioning frame is fixedly installed at one end of the telescopic connecting rod. The positioning frame is located on the other side of the fixed frame, and three positioning clamps are slidably installed on one side of the positioning frame through a built-in electric cylinder.

[0012] Furthermore, an adjusting servo cylinder is fixedly installed inside each of the two fixed frames, and a connecting slider is fixedly installed at the drive end of each of the two adjusting servo cylinders. A connecting groove is provided on the side of the positioning frame near the adjusting servo cylinder, and the connecting slider is slidably installed inside the connecting groove.

[0013] Furthermore, a sliding frame is slidably arranged below the interior of the placement cavity. Both sides of the sliding frame are equipped with transmission gears that are rotated by built-in motors. Both sides of the bottom of the placement cavity are provided with transmission tooth grooves, and the surfaces of the transmission gears on both sides mesh with the interior of the transmission tooth grooves on both sides respectively. A lifting frame is movably arranged on the top of the sliding frame through a built-in electric push rod, and a liquid tank is provided on the top of the lifting frame. The interior of the lifting frame is also equipped with four sets of miniature ultrasonic generators and transducers, with the transducers protruding from the bottom inner wall of the liquid tank.

[0014] Furthermore, a liquid outlet rack is fixedly installed at the bottom of the inside of the frame, and a liquid outlet opening is provided at the top of the liquid outlet rack. A liquid outlet pipe is provided at the bottom of the liquid outlet rack, and one end of the liquid outlet pipe is connected to the inside of the liquid outlet rack.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The plasma jet nozzles and ultrasonic outlets alternately distributed at the bottom of the cleaning frame in this invention, combined with the left and right sliding of the cleaning frame and the flipping action of the housing, realize continuous and coordinated operation of plasma decomposition of organic oil stains, ultrasonic stripping of inorganic impurities, and ultrasonic rinsing of residues, avoiding the limitations of a single cleaning method; at the same time, the liquid tank at the top of the lifting frame and the built-in micro ultrasonic generator transmit ultrasonic energy through the cleaning fluid, so that the cavitation effect covers the bottom, side walls and part of the top area of ​​the housing, effectively solving the problem of dead corners in the bottom cleaning of traditional equipment.

[0016] 2. In this invention, the positioning frame inside the placement cavity is adjustable in spacing through the adjustment of the servo electric cylinder drive. Combined with the opening and closing action of the positioning caliper, it can adapt to compressor housings of various outer diameters and lengths. The pressure sensor set inside the positioning caliper can monitor the clamping force in real time to avoid excessive clamping and deformation of the housing. The protective silicone pad effectively prevents the housing surface from being scratched. At the same time, the rotary servo motor drives the housing to slowly rotate. Combined with the left and right sliding of the cleaning frame and the swing adjustment of the swing spray frame, 360° coverage cleaning of the housing without dead angles is achieved, ensuring uniform cleaning of different areas. There is no need to change tooling for different housing specifications, which improves the applicability and work efficiency of the equipment.

[0017] 3. In this invention, the frame and cleaning rack achieve precise sliding cooperation through the control of servo electric cylinders, slide grooves, and sliding balls. The swing spray rack achieves flexible adjustment of its lateral position and swing angle through a servo linear slide table and a swing servo motor. The linkage actions of each moving part are precisely coordinated through the control system, ensuring the orderly progress of the cleaning process. The equipment adopts an automated operation process of loading, cleaning, and unloading. The entry and exit of the placement rack, the clamping and flipping of the shell, and the start and stop of each cleaning module do not require manual intervention. This not only reduces the labor intensity of operators but also avoids the inconsistencies in cleaning caused by human operation, significantly improving the stability and repeatability of the cleaning operation.

[0020] 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.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1

[0022] Please see Figures 1 to 7 As shown, a surface cleaning treatment device for compressor housing processing includes: a frame 1, a placement rack 2, and a cleaning rack 3. The placement rack 2 is slidably arranged inside the frame 1, and the cleaning rack 3 is slidably arranged on the top of the placement rack 2. The placement rack 2 is located inside the frame 1 and slides back and forth, and the front of the placement rack 2 extends to the outside of the frame 1. The cleaning rack 3 is located on the top of the frame 1 and slides left and right. The top of the cleaning rack 3 is also fixed with a disassembly top plate 29 by a bolt group.

[0023] Specifically, a mounting frame 24 is fixedly installed at the top inside the cleaning rack 3. A plasma chamber is located on the left side of the mounting frame 24, and an ultrasonic chamber is located on the right side. The plasma chamber is connected to an ozone adsorption device via a negative pressure pipeline. The ozone adsorption device employs a combined activated carbon adsorption and catalytic decomposition process to ensure that the ozone generated by the plasma is recovered immediately, preventing damage to operators and equipment circuitry. A plasma generator 25 is installed inside the plasma chamber, and an ultrasonic transducer 26 is installed inside the ultrasonic chamber. The bottom of the plasma chamber and the ultrasonic chamber are separated by a horizontally placed ceramic heat insulation plate. Two plasma jet ports 27 and two ultrasonic outlets 28 are respectively located at the bottom inside the cleaning rack 3, and these ports are alternately distributed on the same plane. The alternating arrangement of the two plasma jet ports 27 and two ultrasonic outlets 28... At the bottom of the cleaning frame 3, a continuous synergistic effect of plasma decomposition → ultrasonic ablation → plasma decomposition → ultrasonic ablation is formed. The plasma jet port 27 adopts a fan-shaped structure design. The airflow channel at the top of the plasma jet port 27 is connected to an external low-pressure air source, and the top of the airflow channel is connected to the plasma generation area. The plasma discharge structure composed of high-voltage electrode + dielectric layer + ground electrode generates active ions such as ozone in the plasma generation area. Then, the active plasma particles are blown to the plasma jet port 27 by compressed air to form an active particle jet beam. The ultrasonic outlet 28 adopts a trumpet-shaped structure design. An amplitude transformer is set at the top of the ultrasonic outlet 28. The amplitude transformer amplifies and focuses the vibration energy converted by the ultrasonic transducer 26 and transmits it to the surface of the compressor housing through the ultrasonic outlet 28 to form a high-intensity ultrasonic cavitation field. The ultrasonic outlet 28 and the amplitude transformer are integrated to ensure lossless transmission of vibration energy.

[0024] Furthermore, servo linear slides 30 are fixedly installed on the front and rear sides of the bottom of the cleaning frame 3, and sliding connecting frames 31 are slidably installed on the opposite side of the two servo linear slides 30. Oscillating spray frames 32 are rotatably installed inside the two sliding connecting frames 31, and a liquid delivery pipe is rotatably connected to one end of the two oscillating spray frames 32. Oscillating servo motors 33 are fixedly installed on one side of the two sliding connecting frames 31, and one end of the output shaft of the two oscillating servo motors 33 is fixedly connected to one side of the two oscillating spray frames 32 respectively. High-pressure nozzles are installed on the opposite side of the two oscillating spray frames 32.

[0025] Furthermore, both sides of the top of the frame 1 are provided with sliding grooves 23, and both sides of the bottom of the cleaning frame 3 are provided with sliding balls, and the surfaces of the sliding balls on both sides are slidably connected to the inside of the sliding grooves 23 on both sides respectively; both sides of the top of the frame 1 are fixedly provided with control servo cylinders 22, and the drive ends of the control servo cylinders 22 on both sides are fixedly connected to the two sides of the cleaning frame 3 respectively.

[0026] It should be noted that during the surface cleaning of the compressor housing, the cleaning frame 3 is controlled to slide left and right on the top of the frame 1 by using the control servo cylinders 22 on both sides. This allows the two plasma jet ports 27 and two ultrasonic outlets 28 at the bottom of the cleaning frame 3 to slide on the top of the compressor housing. First, the inorganic matter on the surface of the compressor housing is peeled off by the ultrasonic outlets 28. Then, the plasma jet is used to decompose the oil stains on the surface of the compressor housing. At this time, the housing is controlled to rotate synchronously to achieve 360-degree coverage cleaning of the housing. Finally, the ultrasonic outlets 28 are used to ultrasonically rinse the surface of the housing to remove surface residues.

[0027] Specifically, servo linear slides 16 are fixedly installed on both sides of the lower part of the rack 1, and the tops of the two servo linear slides 16 are slidably connected to the rear side of the bottom of the placement rack 2; the placement rack 2 is provided with a placement cavity 4, and fixed frames 5 are fixedly installed on both sides of the placement cavity 4. A rotary servo motor 8 is fixedly installed on one side of each of the two fixed frames 5, and a rotary connecting block 9 is fixedly installed at one end of the output shaft of each of the two rotary servo motors 8. A telescopic connecting rod 10 is slidably installed inside the rotary connecting block 9, and a positioning frame 6 is fixedly installed at one end of the telescopic connecting rod 10. The positioning frame 6 is located on the other side of the fixed frame 5, and three positioning clamps 7 are slidably installed on one side of the positioning frame 6 through a built-in electric cylinder. Pressure sensors and protective silicone pads are provided on the inner side of each of the three positioning clamps 7.

[0028] Furthermore, both fixed frames 5 are equipped with adjustable servo cylinders 11, and both adjustable servo cylinders 11 are equipped with connecting sliders 12. The positioning frame 6 is provided with a connecting groove 13 on the side near the adjustable servo cylinder 11, and the connecting slider 12 is slidably positioned inside the connecting groove 13.

[0029] It should be noted that during the cleaning of the compressor housing, the servo linear slide 16 controls the placement rack 2 to slide out from inside the frame 1, placing the compressor housing into the placement cavity 4. According to the size specifications of the compressor housing, the driving ends of the adjusting servo cylinders 11 on both sides are used to push the positioning racks 6 on both sides to move to both sides of the compressor housing. The positioning clamps 7 on one side of the two positioning racks 6 are used to clamp and limit the surface of the compressor housing. During the surface cleaning of the compressor housing, the output shaft of the rotary servo motor 8 controls the rotary connecting block 9 to rotate, thereby realizing the rotation control of the compressor housing and achieving a 360-degree cleaning effect on the surface of the compressor housing. Example 2

[0030] Furthermore, a sliding frame 17 is slidably installed below the interior of the placement cavity 4. Both sides of the sliding frame 17 are equipped with transmission gears 20 that rotate via built-in motors. Both sides of the bottom of the placement cavity 4 are equipped with transmission tooth grooves 21, and the surfaces of the transmission gears 20 on both sides mesh with the interior of the transmission tooth grooves 21 on both sides respectively. A lifting frame 18 is movably installed on the top of the sliding frame 17 via a built-in electric push rod, and a liquid tank 19 is installed on the top of the lifting frame 18. Four sets of miniature ultrasonic generators and transducers are installed inside the lifting frame 18. The transducers protrude from the bottom inner wall of the liquid tank 19 to ensure that the ultrasonic energy is directly transmitted to the cleaning fluid inside the liquid tank 19. A liquid outlet frame 15 is fixedly installed below the interior of the frame 1, and a liquid outlet opening is provided on the top of the liquid outlet frame 15. A liquid outlet pipe is provided on the bottom of the liquid outlet frame 15, and one end of the liquid outlet pipe is connected to the interior of the liquid outlet frame 15.

[0031] It should be noted that when cleaning the surface of the compressor housing, the sliding frame 17 is controlled to slide directly below the compressor housing through the meshing transmission between the transmission gear 20 and the transmission tooth groove 21. Then, the lifting frame 18 is controlled to move upward through the electric push rod inside the sliding frame 17, leaving a certain cleaning gap between the top of the lifting frame 18 and the bottom of the compressor housing. The cleaning liquid is then sprayed onto the surface of the compressor housing by the swinging spray frame 32, while the compressor housing is controlled to rotate, achieving all-round cleaning of the compressor housing. In conjunction with the plasma generator 25 and the ultrasonic transducer 26, the surface of the compressor housing is subjected to plasma treatment and ultrasonic treatment. At the same time, the micro ultrasonic generator and transducer installed inside the lifting frame 18 transmit ultrasonic energy through the cleaning liquid in the liquid tank 19. Meanwhile, the sprayed liquid film forms an ultrasonic conduction medium, allowing the cavitation effect to cover the bottom, side walls and part of the top area of ​​the compressor housing, forming a synergistic effect of mechanical impact and ultrasonic stripping with the spray. Example 3

[0032] Specifically, this embodiment discloses a method for operating a surface cleaning treatment device for compressor housing processing, including the following steps: Step 1: Drive the placement rack 2 to slide back and forth inside the frame 1 using the servo linear slide 16, so that the front of the placement rack 2 extends to the outside of the frame 1, exposing the placement cavity 4. According to the size and specifications of the compressor housing to be cleaned, the drive ends of the servo electric cylinders 11 on both sides push the connecting slider 12 to slide along the connecting groove 13 of the positioning frame 6, causing the positioning frames 6 on both sides to move closer to the housing. At the same time, the built-in electric cylinder on one side of the positioning frame 6 drives the three positioning clamps 7 to open, placing the compressor housing between the two positioning frames 6 in the placement cavity 4. The three positioning clamps 7 close to clamp and limit the surface of the housing. The pressure sensor inside the positioning clamps 7 monitors the clamping force in real time to ensure that the force is controlled within a safe range. The protective silicone pad prevents scratching the surface of the housing. After clamping, the servo linear slide 16 drives the placement rack 2 to retract into the frame 1, completing the loading. Step 2: Drive the transmission gears 20 driven by the built-in motors on both sides of the sliding frame 17 to rotate. Utilize the meshing transmission gears 20 and the transmission tooth grooves 21 at the bottom of the placement cavity 4 to move the sliding frame 17 directly below the compressor housing. The electric push rod inside the sliding frame 17 pushes the lifting frame 18 upward, leaving a preset cleaning gap between the top liquid tank 19 of the lifting frame 18 and the bottom of the compressor housing. Inject an appropriate amount of cleaning fluid into the liquid tank 19 to ensure that the cleaning fluid can form an effective conductive medium. At the same time, the sliding balls on both sides of the bottom of the cleaning frame 3 are in contact with the sliding grooves 23 at the top of the frame 1. The servo electric cylinders 22 on both sides are initially positioned, moving the cleaning frame 3 to the initial cleaning position at one end of the housing. The servo linear slides 30 on the front and rear sides of the bottom of the cleaning frame 3 drive the sliding connecting frame 31 to move, adjusting the lateral position of the swing spray frame 32. The swing servo motor 33 drives the swing spray frame 32 to swing, aligning the high-pressure nozzle with the housing surface. The liquid delivery pipe is connected to the cleaning fluid source, preparing for spraying. Step 3: Start the control servo cylinder 22 to drive the cleaning frame 3 to slide left and right along the top of the frame 1. At the same time, start the rotary servo motor 8, whose output shaft drives the rotary connecting block 9 and the telescopic connecting rod 10 to rotate, thereby driving the compressor housing to slowly rotate at a preset speed to achieve 360° coverage. During the movement of the cleaning frame 3, the ultrasonic transducer 26 inside the ultrasonic cavity first works to convert electrical energy into high-frequency vibration. After being amplified and focused by the amplitude transformer, it is transmitted to the cleaning fluid on the surface of the housing through the horn-shaped ultrasonic outlet 28, forming a high-intensity ultrasonic cavitation field to peel off the metal debris, rust and other inorganic matter on the surface of the housing. Subsequently, the plasma generator 25 inside the plasma cavity is started, driven by the high-voltage electrode The discharge structure, consisting of a dielectric layer and a grounding electrode, generates active particles such as ozone. An external low-pressure gas source introduces compressed air into the plasma generation area through an airflow channel, blowing the active particles to the fan-shaped plasma jet nozzle 27 to form an active particle jet beam, which decomposes oil and organic residues on the shell surface. Since the two plasma jet nozzles 27 and the two ultrasonic outlets 28 are alternately distributed on the same plane, the sliding of the cleaning frame 3 and the flipping of the shell are synchronized, realizing the continuous synergistic effect of plasma decomposition → ultrasonic stripping → plasma decomposition → ultrasonic stripping. The ozone adsorption device connected to the plasma chamber through the negative pressure pipeline works synchronously, and the ozone is recovered by a composite process of activated carbon adsorption + catalytic decomposition to avoid leakage hazards. Step 4: After the collaborative cleaning is completed, the plasma generator 25 stops working, the ultrasonic transducer 26 continues to work, and the ultrasonic outlet 28 performs ultrasonic rinsing on the shell surface to remove residual small molecule decomposition products and tiny impurities. At the same time, the high-pressure nozzles of the swing spray frame 32 spray high-pressure cleaning fluid, which, together with the ultrasonic rinsing, washes the shell surface. The swing servo motor 33 drives the swing spray frame 32 to swing continuously, and the servo linear slide 30 drives the sliding connecting frame 31 to move laterally, ensuring that the high-pressure water flow covers the entire surface of the shell and washes the impurities into the liquid tank 19 below. The four sets of miniature ultrasonic generators and transducers inside the lifting frame 18 work synchronously. The ultrasonic energy is transmitted through the cleaning fluid in the liquid tank 19. Combined with the liquid film formed by the spray as the ultrasonic transmission medium, the cavitation effect covers the bottom, side walls and part of the top area of ​​the shell, realizing a secondary enhanced cleaning of mechanical impact + ultrasonic peeling. Step 5: After the cleaning process is completed, the ultrasonic transducer 26, high-pressure nozzle, and miniature ultrasonic generator stop working. The lifting frame 18 is lowered and reset via the electric push rod, and the sliding frame 17 returns to its initial position through the meshing of the transmission gear 20 and the transmission tooth groove 21. The rotary servo motor 8 stops working, the positioning clamp 7 of the positioning frame 6 opens, and the servo linear slide 16 drives the placement frame 2 to slide outward from the frame 1. The operator removes the cleaned compressor housing to complete the unloading. Finally, the waste liquid in the liquid tank 19 flows into the liquid outlet pipe through the liquid outlet opening of the liquid outlet frame 15 and is discharged. The equipment automatically resets and prepares for the next cleaning operation.
