Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning compressor production, in particular to a surface cleaning system before spraying of automobile air-conditioning compressor parts. Background Art

[0002] The piston ring of the automobile air-conditioning compressor is an important component in the automobile air-conditioning system. It is mainly used to seal the gas inside the compressor to prevent gas leakage and ensure the efficient operation of the compressor. In order to improve the performance of the piston ring, it is necessary to spray polytetrafluoroethylene on its surface during the manufacturing of the piston ring. The polytetrafluoroethylene material has good wear resistance and low friction properties. However, the piston ring needs to be thoroughly cleaned before spraying to ensure that the polytetrafluoroethylene has the best adhesion effect on the surface of the piston ring. If there is grease, dust or other contaminants on the surface, the adhesion of the spray layer will be reduced, thus affecting the final quality and service life.

[0003] At present, there are the following disadvantages in cleaning the piston ring: 1. Usually, multiple piston rings are directly placed in a cleaning device, cleaned by water immersion, and the piston rings are taken out one by one after cleaning. However, during the cleaning process, the piston rings are in a state of stacking on each other, and the dirt and sludge in the stacked parts are difficult to be completely removed by the cleaning agent, resulting in incomplete cleaning of the piston rings, which affects the subsequent spraying of polytetrafluoroethylene; 2. When cleaning the piston ring, grease, dust and other contaminants attached to the piston ring are precipitated by the cleaning liquid and enter the cleaning liquid. As the concentration of contaminants in the cleaning liquid increases, the cleaning efficiency of the cleaning liquid will continue to decrease. At this time, the cleaning liquid can only be continuously replaced or filtered to maintain the cleaning effect of the cleaning liquid, but frequent replacement of the cleaning liquid will increase the cleaning cost and prolong the time of the entire cleaning process, thereby reducing the cleaning efficiency of the piston ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes efficient cleaning of multiple piston ring surfaces by using the loading mechanism, brushing mechanism and cleaning mechanism in coordination with each other, and adopts an integrated operation model of loading, brushing and cleaning, and at the same time, a limiting and fixing mechanism is set to ensure that the piston ring maintains the correct position during the cleaning process, and the surface of each piston ring is accurately brushed and rinsed, and the piston ring is placed vertically and expanded and fixed to maximize the contact area between the cleaning liquid and the piston ring and reduce the risk of cross contamination and damage, and at the same time, by synchronously brushing the inner and outer ring walls and side walls of the piston ring and combining brushing and flushing, the piston ring is ensured to be fully and evenly cleaned, the cleaning efficiency and quality are improved, and a good pretreatment is provided for the spraying of polytetrafluoroethylene, thereby improving the overall work efficiency.

[0017] 2. The present invention arranges a loading mechanism to place multiple piston rings in a vertical position, thereby exposing more ring surfaces to facilitate subsequent effective cleaning, while reducing contact between piston rings to reduce the probability of cross contamination, and expanding and fixing the openings of the piston rings to reduce the possibility of collision of the piston rings during the cleaning process and reduce the risk of damage. At the same time, the fixed piston rings are easier to take out and place after cleaning, which reduces the operation time and improves work efficiency.

[0018] 3. The present invention can synchronously brush the inner ring wall, outer ring wall and side wall of the piston ring through the coordinated use of the brushing mechanism and the loading mechanism, ensuring that the inner and outer sides and side walls of each piston ring can be evenly cleaned, with a wide coverage and high cleaning quality, which provides convenience for the subsequent spraying of polytetrafluoroethylene.

The present invention uses a brushing mechanism and a cleaning mechanism in coordination with each other to simultaneously clean the surfaces of multiple piston rings by combining brushing and flushing. Brushing can physically remove stubborn dirt on the surface of the piston ring, while flushing can help remove loose dirt and detergents, thereby significantly improving the cleaning efficiency. At the same time, the combination of brushing and flushing can deeply clean the hard-to-reach areas on the piston ring, thereby improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting portion 41 includes a limiting arc plate 411, a limiting block 412 and a horizontal block 413. The limiting arc plate 411 that is symmetrical in front and back is fixedly installed between the left and right symmetrical supporting circular plates 2. The side walls of the left and right symmetrical supporting circular plates 2 that are close to each other are installed with horizontal blocks 413 that are symmetrical in front and back and extend horizontally along the radial direction of the supporting circular plates 2. The limiting arc plate 411 is located below the horizontal block 413. The side walls of the left and right symmetrical limiting arc plates 411 that are close to each other are fixedly installed with a plurality of block groups in a linear array, and each block group includes two limiting blocks 412 distributed on the left and right.

[0033] See also Figure 1 , Figure 2 and Figure 3 The deflection portion 42 includes a revolving plate 421, a first motor 422, a first shaft 423, a connecting plate 424 and a support block 425. The revolving plate 421 is installed on one side wall of the support circular plate 2 close to each other through a bearing.

[0034] See also Figure 1 , Figure 2 and Figure 3The fixing part 43 includes a bidirectional screw 431, a second motor 432, a clamping slider 433 and an extrusion plate 434. The side walls of the support blocks 425 that are close to each other are provided with a first limiting slide, and the clamping sliders 433 that are symmetrical front and rear are slidably installed in the first limiting slide.

[0035] During specific work, when the piston ring needs to be cleaned, first place the piston ring with its opening facing downward between the two limit blocks 412. At this time, the front and rear symmetrical limit arc plates 411 will support the piston ring in the front and rear directions, and the limit blocks 412 on both sides will limit the left and right movement of the piston ring, so that the piston ring is placed in a vertical state, thereby exposing more ring surface to facilitate subsequent cleaning, and then all piston rings are placed in the same operation.

[0036] At this time, the front-to-back symmetrical extrusion plate 434 is just located between the openings of the piston ring. Then the second motor 432 is started to rotate the bidirectional screw 431, thereby driving the corresponding front-to-back symmetrical clamping sliders 433 to move synchronously in opposite directions, so that the front-to-back symmetrical extrusion plates 434 expand to both sides and fix the opening of the piston ring, thereby reducing the possibility of collision of the piston ring during the cleaning process.

[0037] During the brushing process of the brushing mechanism 5, the first motor 422 is started to rotate the rotating plate 421 through the cooperation of the teeth and the first gear, thereby driving the support block 425 to rotate around the center point of the rotating plate 421, and rotating the piston ring through the fixing part 43 to expose the side wall where the piston ring contacts the limit arc plate 411 and the limit block 412, so that the brushing mechanism 5 can clean this part, avoiding the existence of cleaning dead corners, and ensuring that the piston ring can be effectively cleaned.

[0038] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The rotating part 51 includes a supporting shaft cylinder 511, a third motor 512 and a fixed cylinder 513. The supporting shaft cylinder 511 located at the axial position is installed through the bearing between the left and right symmetrical supporting circular plates 2.

The output end of the third motor 512 is connected to the supporting shaft cylinder 511 through a first transmission gear set. A plurality of fixed cylinders 513 located between the two corresponding left and right limit blocks 412 are fixedly installed in a linear array on the supporting shaft cylinder 511.

[0039] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The alignment part 52 includes a bidirectional screw sleeve 521, an alignment sleeve 522, a second shaft rod 523 and a fourth motor 524. A bidirectional screw sleeve 521 corresponding to the fixed cylinder 513 and located directly below the corresponding fixed cylinder 513 is rotatably installed on the support shaft cylinder 511 through a bearing seat. An alignment sleeve 522 symmetrically installed on the left and right sides of the corresponding fixed cylinder 513 is slidably installed on the support shaft cylinder 511. The symmetrical alignment sleeve 522 is threadedly connected with the corresponding bidirectional screw sleeve 521. A second shaft rod 523 is fixedly installed at the center of several bidirectional screw sleeves 521. A fourth motor 524 with an output end fixedly connected to the second shaft rod 523 is fixedly installed on the support shaft cylinder 511.

[0040] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 The scrubbing part 53 includes a support arm 531, a scrubbing block 532, a matching plate 533, a fixing plate 534 and a matching plug rod 535. The upper end of the alignment sleeve 522 is fixedly mounted with the support arm 531, and the upper end of the support arm 531 is fixedly mounted with the scrubbing block 532. A rotation groove is provided on the upper end surface of the scrubbing block 532, and a matching plate 533 is hingedly connected to the rotating groove through a torsion spring rod. The matching plates 533 symmetrically disposed on the upper side of the same fixed cylinder 513 are fixedly mounted with the fixing plate 534 on one side wall close to each other. 4. A long-bristled brush is provided on one side wall of the mutually adjacent fixed plates 534 which are symmetrical on the left and right above the same fixed cylinder 513. A short-bristled brush is provided on one side wall of the mutually adjacent matching plates 533 which are symmetrical on the left and right above the same fixed cylinder 513 and on the upper end surface of the scrubbing block 532. Two matching plug rods 535 which are distributed vertically are fixedly mounted on the support arm 531 which is located on the right side above the same fixed cylinder 513. A socket which matches with the matching plug rod 535 is provided on the support arm 531 which is located on the left side.

[0041] During specific operation, after the fixing part 43 completes the fixation of the piston ring opening, the external water pump is started to supply water to the cleaning mechanism 6, and at the same time, the fourth motor 524 is started to rotate the second shaft rod 523, so that the two-way screw sleeve 521 brings the positioning sleeves 522 on both sides to approach the corresponding fixed cylinder 513 synchronously, so that the support arms 531 on both sides bring their respective brush blocks 532 close to the piston ring, and stop running the fourth motor 524 when the matching plug rod 535 is inserted into the socket, and the matching plug rod 535 and the socket cooperate to combine the support arms 531 on both sides into a whole, so that it is more stable when rotating with the support shaft cylinder 511.

[0042] At this time, the matching plates 533 on both sides carry short-bristled brushes in contact with the side walls of the piston ring, and the short-bristled brushes on the upper end faces of the brushing blocks 532 contact with the inner ring walls of the piston rings. The fixed plates 534 on both sides carry corresponding long-bristled brushes in contact with each other and the outer ring walls of the piston rings. Subsequently, the third motor 512 is started to rotate the support shaft cylinder 511 through the first transmission gear group. The support shaft cylinder 511 causes the support arms 531 on both sides to reciprocate, thereby synchronously brushing the inner ring wall, outer ring wall and side walls of the piston ring to ensure that the inner and outer sides and side walls of each piston ring can be evenly cleaned.

[0043] When the support arm 531 drives the matching plate 533 to reach the limiting arc plate 411 or the extrusion plate 434, the matching plate 533 will be squeezed in the direction opposite to its rotation direction, so that the matching plate 533 rotates around its hinge point, so that the support arm 531 can continue to rotate, and when the support arm 531 reaches the other side of the limiting arc plate 411 or the extrusion plate 434, the matching plate 533 resets and rotates under the action of the torsion spring, and then cooperates with the deflection part 42 and the fixing part 43 to change the position of the piston ring to expose its surface, thereby completing the comprehensive cleaning of the piston ring surface and ensuring the subsequent polytetrafluoroethylene spraying quality.

[0044] See also Figure 1 , Figure 4 and Figure 6 The matching part 54 includes a triangular plate 541 and a pressure roller 542. The side walls of the left-right symmetrical support arms 531 above the same fixed cylinder 513 that are close to each other are fixedly installed with front-to-back symmetrical triangular plates 541. The end of the front-to-back symmetrical triangular plates 541 away from the corresponding support arms 531 is installed with a pressure roller 542 located above the corresponding fixed cylinder 513 through a bearing.

[0045] See also Figure 1 , Figure 4 and Figure 6The switching part 61 includes a central connecting pipe 611, a water distribution pipe 612, a cone cylinder 613, a blocking block 614 and a water supply pipe 615. The central connecting pipe 611 is fixedly installed through the axis of the supporting shaft cylinder 511, and the central connecting pipe 611 is fixedly installed with a water distribution pipe 612 corresponding to the fixed cylinder 513 one by one. The water distribution pipe 612 is located at the axis of the fixed cylinder 513. The fixed cylinder 513 is slidably installed with a cone cylinder 613 sleeved on the outer ring wall of the corresponding water distribution pipe 612 through a set spring. The upper end of the cone cylinder 613 is fixedly installed with a blocking block 614 for blocking the water distribution pipe 612 through a set support rod, and the right end of the central connecting pipe 611 is fixedly connected with a water supply pipe 615 connected thereto.

[0046] See also Figure 1 and Figure 2 The flushing part 62 includes an external pipe 621, a nozzle 622 and a connecting pipe 623. The front-to-back symmetrical external pipe 621 is fixedly installed between the left-right symmetrical supporting circular plates 2. The external pipe 621 is located above the corresponding limiting arc plate 411. A plurality of nozzles 622 are fixedly installed in a linear array on the side where the front-to-back symmetrical external pipes 621 are close to each other. The front-to-back symmetrical external pipes 621 are connected to the water supply pipe 615 through the arranged connecting pipe 623.

[0047] During specific operation, as the support arms 531 on both sides approach each other, the triangular plate 541 drives the pressure roller 542 to move along with the support arms 531, and the pressure rollers 542 on both sides push the conical cylinder 613 into the fixed cylinder 513, thereby blocking the water outlet of the water distribution pipe 612 with the blocking block 614. At this time, the brushing mechanism 5 brushes and cleans the piston ring to physically remove stubborn dirt on the surface of the piston ring.

[0048] After the scrubbing is completed, the fourth motor 524 is started in reverse so that the support arms 531 on both sides move away synchronously. At this time, the squeezing force of the cone cylinder 613 on the pressure roller 542 disappears, and the cone cylinder 613 moves upward under the action of the spring rebound force, thereby releasing the water outlet of the water distribution pipe 612. At this time, the external water pump supplies water to the central connecting pipe 611 through the water supply pipe 615, so that the water distribution pipe 612 sprays water to flush the piston ring. At the same time, the connecting pipe 623 supplies water to the front and rear symmetrical external through pipes 621 and sprays water from the nozzle 622, which also flushes the piston ring to remove dirt and detergent on its surface, thereby combining scrubbing and flushing to synchronously clean the surfaces of multiple piston rings, significantly improving the cleaning efficiency, and during the flushing process, the nozzle 622 will perform a certain high-pressure flushing on the long-bristle brush and the short-bristle brush to ensure the cleaning state of both.

[0049] After the piston rings are cleaned, the second motor 432 can be started in reverse to release the fixing of the piston rings, and then the piston rings can be taken out one by one.

[0050] See also Figure 1-Figure 7 Working principle: When the piston ring needs to be cleaned, first place the piston ring with its opening facing downward between the two limit blocks 412. At this time, the front and rear symmetrical extrusion plates 434 are located between the openings of the piston ring. Then, start the second motor 432 to fix the opening of the piston ring through the fixing part 43.

[0051] Then, the external water pump is started to supply water to the cleaning mechanism 6. At the same time, the fourth motor 524 is started to cooperate with the positioning part 52 and the brushing part 53 to bring their respective brushing blocks 532 close to the piston ring, and with the cooperation of the rotating part 51, the inner ring wall, outer ring wall and side wall of the piston ring are synchronously brushed. At the same time, the deflection part 42 and the fixing part 43 are cooperated to change the position of the piston ring to expose its surface, thereby completing the comprehensive cleaning of the piston ring surface.

[0052] After the scrubbing is completed, the fourth motor 524 is started in reverse so that the support arms 531 on both sides move away synchronously, and the water outlet of the water distribution pipe 612 is released. At this time, the external water pump supplies water to the central connecting pipe 611 through the water supply pipe 615, so that the water distribution pipe 612 sprays water to wash the surface of the piston ring. At the same time, the connecting pipe 623 supplies water to the front and rear symmetrical external through pipes 621, and sprays water from the nozzle 622, which also washes the surface of the piston ring to remove dirt and detergent on the surface. In the process of washing, the nozzle 622 will perform a certain high-pressure washing on the long-bristle brush and the short-bristle brush.

[0053] After the piston rings are cleaned, the second motor 432 can be started in reverse to release the fixing of the piston rings, and then the piston rings can be taken out one by one.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
