Description

Technical Field

[0001] This invention belongs to the field of water pump processing technology, and in particular relates to a grinding device for water pump inlet rings. Background Technology

[0002] The pump inlet ring (also known as a sealing ring or wear-resistant ring) is a ring-shaped metal component installed between the pump impeller and the pump body. Its core function is to control the gap between the impeller and the pump body, prevent the pump outlet medium from flowing back to the inlet end, and at the same time play a wear-resistant protection role, avoiding direct contact and wear between the impeller and the pump casing. Its precision directly affects the pump's flow rate, pressure and overall efficiency.

[0003] A search revealed Chinese Patent Publication No. CN118493168A, which discloses a water pump impeller grinding device. The device includes a fixed outer shell, a water pump impeller placement box, and a rotating grinding box. Multiple grinding columns within the rotating grinding box are elastically displaced vertically by deformable springs, allowing it to adapt to water pump impellers of different shapes and sizes. This effectively conforms to the curved surface of the impeller, ensuring uniform and consistent grinding. The elastic snap-fit ​​connection between the connecting rod and the interface, along with the combined use of a limiting block and elastic spring, ensures the stability of the rotating grinding box during rotation and makes the device easy to use. The rotating grinding box flexibly follows the rotation of the water pump impeller placement box. Simultaneously, the movement of rollers on an annular wave guide rail creates a speed difference between the rotating grinding box and the water pump impeller placement box, thereby achieving efficient grinding of the water pump impeller.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing grinding devices cannot be adapted to different specifications of inlet rings, resulting in poor overall versatility of the grinding devices. Furthermore, during the grinding process, positioning deviations of the water pump inlet ring are prone to occur, leading to insufficient grinding precision and consequently affecting the grinding quality of the grinding devices.

Under the action of the connecting spring, the limiting rod drives the inner grinding block to be in contact with the inner surface of the water pump inlet ring. Under the action of the second motor, the rotating disc rotates, thereby driving the inner grinding block to grind the inner surface of the water pump inlet ring.

[0029] 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.

[0030] In specific implementation, such as Figures 1-8 As shown, the present invention provides a technical solution: a grinding device for a water pump inlet ring, including a base 1, a cover 2 fixedly installed on the upper surface of the base 1, an operation box 3 fixedly installed on the side wall of the base 1, a debris collection mechanism 4 and a peripheral positioning mechanism 6 provided on the upper surface of the base 1, an inner positioning mechanism 7 provided on the inner wall of the peripheral positioning mechanism 6, and sliding grooves 8 symmetrically arranged on the upper surface of the base 1, with a grinding mechanism 5 provided on the inner wall of the sliding grooves 8; wherein, the peripheral positioning mechanism 6 includes a mounting base 601, the lower surface of the mounting base 601 is fixedly connected to the upper surface of the base 1, a groove 602 is provided on the side wall of the mounting base 601, a reciprocating motor 603 is rotatably installed on the inner side wall of the groove 602, and a movable disk 604 is fixedly installed on the output end of the reciprocating motor 603 through a drive shaft, with a drive groove 605 provided on the side wall of the movable disk 604.

[0031] A fixed plate 606 is fixedly installed on the inner surface of the groove 602. The side wall of the fixed plate 606 fits against the side wall of the movable plate 604. A positioning groove 607 is provided on the inner wall of the fixed plate 606, and the positioning groove 607 passes through the interior of the fixed plate 606.

[0032] A fixing post 608 is fixedly installed on the inner surface of the groove 602. The side wall of the fixing post 608 fits against the side wall of the fixing plate 606. Several moving grooves 609 are evenly arranged inside the fixing post 608. The moving grooves 609 penetrate through the interior of the fixing post 608. A placement groove is provided at the center of the fixing post 608.

[0033] The peripheral positioning mechanism 6 also includes a clamping rod 6010. The outer surface of the clamping rod 6010 is slidably connected to the inner wall of the moving groove 609. A slide rod 6011 is fixedly installed at one end of the clamping rod 6010. One end of the slide rod 6011 passes through the positioning groove 607 and extends into the interior of the driving groove 605. The other end of the clamping rod 6010 extends to the outside of the other side wall of the fixed column 608. A sliding groove 6012 is provided on the side wall of the clamping rod 6010. A positioning spring 6014 is fixedly installed on the inner side wall of the sliding groove 6012. A slider 6015 is fixedly installed at one end of the positioning spring 6014. The outer surface of the slider 6015 is slidably connected to the inner wall of the sliding groove 6012. A moving clamping block 6016 is fixedly installed on the upper surface of the slider 6015. A fixing clamping block 6013 is fixedly installed on the side wall of the clamping rod 6010. The fixing clamping block 6013 is close to the end of the clamping rod 6010.

[0034] Specifically, by setting the peripheral positioning mechanism 6, the reciprocating motor 603 drives the movable disk 604 to rotate. At this time, under the action of the drive groove 605, the slide rod 6011 will be displaced in the positioning groove 607 of the fixed disk 606. At this time, the slide rod 6011 drives the clamping rod 6010 to move in the moving groove 609, thereby causing several clamping rods 6010 to retract towards the center of the fixed column 608 or expand towards the periphery of the fixed column 608, so that the distance between the clamping rods 6010 is the same as the outer diameter of the water pump inlet ring. Then the moving clamping block 60 16 moves within the slide groove 6012 under the action of slider 6015, so that the distance between the movable clamping block 6016 and the fixed clamping block 6013 is the same as the thickness of the water pump port ring. Then, the water pump port ring is placed between the movable clamping block 6016 and the fixed clamping block 6013. Under the action of positioning spring 6014, slider 6015 drives movable clamping block 6016 to fix the water pump port ring, thereby exposing the inner surface of the water pump port ring by fixing the outer periphery of the water pump port ring. Then, the inner surface of the water pump port ring is polished under the action of polishing mechanism 5.

[0035] The inner positioning mechanism 7 includes a horizontal adjustment cylinder 701. One end of the horizontal adjustment cylinder 701 is fixedly connected to the inner side wall of the placement groove. The other end of the horizontal adjustment cylinder 701 is fixedly installed with a threaded cylinder 702. A positioning plate 703 is fixedly installed on the outer surface of the threaded cylinder 702. Several through slots 704 are evenly arranged on the side wall of the positioning plate 703.

[0036] A slide cylinder 705 is fitted onto the outer surface of the threaded cylinder 702. A threaded rod 706 is rotatably mounted on the inner wall of the cavity of the slide cylinder 705. The outer surface of the threaded rod 706 is threadedly connected to the inner wall of the threaded cylinder 702. Several fixing strips 707 are fixedly mounted at equal intervals on the outer surface of the slide cylinder 705. A connecting rod 708 is rotatably mounted on both sides of the fixing strip 707 via a rotating shaft. An installation strip 709 is rotatably mounted on one end of the connecting rod 708 via a rotating shaft. An expansion plate 7010 is fixedly mounted on the side wall of the installation strip 709. A limiting slider 7011 is fixedly mounted on the side wall of the expansion plate 7010. The limiting slider 7011 is slidably connected to the inner wall of the through groove 704.

[0037] Specifically, by setting the inner circumference positioning mechanism 7, the horizontal adjustment cylinder 701 drives the threaded cylinder 702 to move to one side of the mounting base 601. Then, by rotating the threaded rod 706, under the action of the threaded cylinder 702, the threaded rod 706 will drive the sliding cylinder 705 to move on the surface of the threaded cylinder 702. As the sliding cylinder 705 moves, under the action of the fixing strip 707, the connecting rod 708 and the mounting strip 709, the expansion plate 7010 expands or contracts under the limitation of the limiting slider 7011 and the through groove 704, thereby fixing the inner surface of the water pump port ring and exposing the outer surface of the water pump port ring. Then, the grinding mechanism 5 grinds the outer surface of the water pump port ring.

[0038] The grinding mechanism 5 includes two threaded posts 501, which are rotatably connected to the inner sidewalls of two sliding grooves 8 respectively. One end of the threaded post 501 extends to the outside of the sidewall of the base 1. A servo motor 502 is symmetrically fixedly mounted on the sidewall of the base 1 through a fixed seat. One end of the threaded post 501 is fixedly connected to the output end of the servo motor 502.

[0039] A threaded sliding sleeve 503 is threadedly installed on the outer surface of the threaded column 501. The outer surface of the threaded sliding sleeve 503 is slidably connected to the inner wall of the sliding groove 8. An mounting plate 504 is fixedly installed on the upper surface of the threaded sliding sleeve 503. A support column 505 is fixedly installed on the upper surface of the mounting plate 504. A fixing cylinder 506 is fixedly installed on the upper surface of the support column 505. A transverse adjusting cylinder 507 is fixedly installed on the inner side wall of the fixing cylinder 506. One end of the transverse adjusting cylinder 507 extends to the outside of the fixing cylinder 506 and is fixedly installed with an mounting sleeve 508.

[0040] A first motor 509 is fixedly installed on the side wall of the mounting sleeve 508. The output end of the first motor 509 is fixedly installed with a peripheral grinding disc 5010 via a rotating shaft. A second motor 5011 is fixedly installed on the side wall of another mounting sleeve 508. The output end of the second motor 5011 is fixedly installed with a rotating disc 5012 via a rotating shaft. Several limiting grooves 5013 are evenly spaced on the outer surface of the rotating disc 5012. A connecting spring 5014 is fixedly installed on the inner side wall of the limiting groove 5013. A limiting rod 5015 is fixedly installed on one end of the connecting spring 5014. One end of the limiting rod 5015 extends to the outside of the limiting groove 5013 and is fixedly installed with an inner grinding block 5016.

[0041] Specifically, by setting up the grinding mechanism 5, when grinding the outer surface of the water pump inlet ring, the servo motor 502 drives the threaded column 501 to rotate in the sliding groove 8. Under the action of the thread, the threaded sleeve 503 moves in the sliding groove 8, thereby driving the mounting plate 504 to move above the base 1. The support column 505 drives the fixed cylinder 506 to move synchronously. The fixed cylinder 506 adjusts the outer grinding disc 5010 to a position horizontal with the water pump inlet ring through the horizontal adjustment cylinder 507 and the mounting sleeve 508. Then, the horizontal adjustment cylinder 507 moves the grinding disc through the mounting sleeve 508, so that the outer surface of the outer grinding disc 5010 fits against the outer periphery of the water pump inlet ring. Under the action of the first motor 509, the outer grinding disc 5010 grinds the outer periphery of the water pump inlet ring. When grinding the inner surface of the water pump inlet ring, the outer grinding disc 5010 is moved to the position of the mounting base 601 so that the outer grinding disc 5010 does not obstruct the work of the inner grinding block 5016. Another horizontal adjustment cylinder 507 drives the rotating disc 5012 to move through the mounting sleeve 508 so that the center of the mounting disc is aligned with the center of the water pump inlet ring. Then, another servo motor 502 moves the rotating disc 5012 to the inside of the water pump inlet ring in the same way. Under the action of the connecting spring 5014, the limiting rod 5015 drives the inner grinding block 5016 to fit against the inner surface of the water pump inlet ring. Under the action of the second motor 5011, the rotating disc 5012 rotates, thereby driving the inner grinding block 5016 to grind the inner surface of the water pump inlet ring.

[0042] The debris collection mechanism 4 includes a collection trough 401, which is disposed on the upper surface of the base 1. A collection cover 402 is fixedly installed on the lower surface of the base 1. The collection cover 402 corresponds to the collection trough 401. A dust extraction pipe 403 is installed on the lower surface of the collection cover 402. One end of the dust extraction pipe 403 is fixedly connected to the input end of the dust extraction fan.

[0043] Specifically, by setting up a debris collection mechanism 4, the input end of the dust extraction fan is connected to the dust extraction pipe 403 through a flange. Then, during the grinding process of the water pump inlet ring, the suction force generated by the dust extraction fan causes the dust extraction pipe 403 to absorb the debris and dust inside the machine cover 2 through the collection cover 402, and then the collected debris is cleaned uniformly.

[0044] Working principle: Fix the base 1 on a stable ground, then open the cover 2, and fix the water pump inlet ring to be polished onto the outer positioning mechanism 6. After it is fixed, the inner grinding block 5016 in the polishing mechanism 5 polishes the inner surface of the water pump inlet ring. Then, the inner positioning mechanism 7 moves to the outside of the outer positioning mechanism 6 to remove the water pump inlet ring from the outer positioning mechanism 6. The inner surface of the water pump inlet ring is then fixed by the inner positioning mechanism 7. Then, under the action of the outer grinding disc 5010 in the polishing mechanism 5, the outer surface of the water pump inlet ring is polished, thereby polishing the inner and outer surfaces of the water pump inlet ring. During the polishing process, the debris collection mechanism 4 absorbs the debris generated by the polishing under the action of the dust extraction fan, and then cleans the debris uniformly.
