Description

Technical Field

[0001] The invention relates to the technical field of water pump core shaft grinding, in particular to a water pump rotor core shaft outer cylindrical grinding processing device. Background Art

[0002] The rotor in a water pump drives the impeller, and its coils are fixed to the core shaft. The rotor's output efficiency is closely related to the smoothness of the core shaft's outer surface. A smooth core shaft outer surface can reduce friction loss, improve rotor rotation efficiency, and thus enhance the overall performance of the water pump. Therefore, in actual production, the outer surface of the water pump rotor core shaft requires high-precision grinding to achieve the required surface quality and dimensional accuracy.

[0003] Cylindrical grinding typically involves mounting a workpiece on a spindle chuck and rotating it against a high-speed grinding wheel. During the grinding process, the grinding wheel's side contacts the workpiece, continuously cutting material and gradually wearing out. This causes the abrasive grains on the wheel's side to become blunt, reducing cutting capacity and impacting grinding efficiency and quality. Because the degree of wear may vary across different parts of the wheel's side, the shape of the wheel's side changes after extended periods of grinding, no longer retaining its initial regular shape. This affects the contact between the wheel and the workpiece, leading to a decrease in grinding accuracy. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A water pump rotor core shaft cylindrical grinding device, comprising:

[0005] A workbench, wherein a clamping component is fixedly connected to the top of the workbench, a transmission component is fixedly connected to the side of the workbench, and a cooling component is fixedly connected to the side of the workbench away from the transmission component;

[0006] A grinding component, which is used to grind the water pump rotor core shaft, and the grinding component is installed on the transmission component;

[0007] The grinding component includes a fixed housing, the bottom of the fixed housing is connected to the output end of the transmission component, both sides of the fixed housing are fixedly connected to a fixed frame, the inner side of the fixed frame is rotatably connected to the grinding wheel, the side of the fixed frame is fixedly connected to the motor, the output end of the motor is fixedly connected to the side of the grinding wheel, and the inner side of the fixed housing is fixedly connected to a connecting mechanism;

[0008] By turning on the motor, the output end of the motor drives the grinding wheel to rotate on the fixed frame, so that the grinding wheel grinds the core shaft. At the same time, when the grinding wheel rotates, it contacts and moves with the connecting mechanism, so that the connecting mechanism performs a slight grinding work on the side of the grinding wheel.

[0009] The connecting mechanism includes a connecting shell, a side surface of the connecting shell is fixedly connected to the inner side of the fixed shell, a collecting box is fixedly connected to the side of the connecting shell, a side of the collecting box away from the connecting shell is fixedly connected to an air suction machine, a mesh plate 1 is fixedly connected to the inner side of the collecting box, a side surface of the collecting box away from the air suction machine is fixedly connected to a mesh plate 2, a rotating roller is rotatably connected to the middle part of the inner side of the connecting shell, a side protrusion of the rotating roller contacts the side surface of the grinding wheel, and both sides of the inner side of the connecting shell close to the rotating roller are rotatably connected to the roughening assembly;

[0010] When the output end of the motor drives the grinding wheel to rotate on the fixed frame, the rotating roller rotates against the grinding wheel through the convex blocks on the surface, so that the rotating roller drives the roughening components on both sides to rotate in the opposite direction of the grinding wheel, so that the roughening components grind the side of the grinding wheel. At the same time, the suction machine is turned on, and the suction force generated by the suction machine when it is working will collect the debris and impurities generated during the grinding of the grinding wheel into the collection box through the second screen plate for collection.

[0011] Preferably, the connecting assembly includes a contact shaft, both ends of which are rotatably connected to the inner side of the connecting shell, a contact roller is fixedly connected to the side of the contact shaft, and the side of the contact roller is evenly provided with a clearance groove, the inner side of the clearance groove contacts the protrusion on the side of the rotating roller, and the side of the contact roller away from the clearance groove is fixedly connected to the extrusion sleeve;

[0012] When the rotating roller rotates along with the grinding wheel, the protrusion on the rotating roller comes into contact with the give way groove on the contact roller, so that when the rotating roller and the grinding wheel rotate against each other, the rotating roller drives the contact roller and the grinding wheel to rotate in the opposite direction, so that when the grinding wheel grinds the mandrel, the contact roller drives the extrusion kit to rotate in the opposite direction to the side of the grinding wheel, thereby grinding and dressing the side of the grinding wheel;

[0013] The extrusion kit includes an extrusion plate, a side surface of the extrusion plate is fixedly connected to the inner side of the contact roller, a connecting block is slidably connected to the side surface of the extrusion plate, a side of the connecting block away from the extrusion plate is fixedly connected to the side surface of the grinding block, both sides of the extrusion plate close to the connecting block are slidably connected to a connecting shaft, the other end of the connecting shaft is fixedly connected to the grinding block, a first spring is sleeved on the connecting shaft, one end of the first spring is fixedly connected to the grinding block, and the other end of the first spring is fixedly connected to the extrusion plate;

[0014] When the contact roller is driven by the rotating roller, it rotates in the connecting housing, so that the contact roller drives the grinding block and the side of the grinding wheel to grind and trim through the connecting block and the connecting shaft;

[0015] At the same time, when the extrusion force between the grinding block and the grinding wheel surface is greater than the tensile force of the first spring, the first spring pulls the grinding block to move through the connected axial extrusion plate, thereby avoiding excessive extrusion force between the grinding block and the grinding wheel, which would cause friction damage to the grinding wheel and the grinding block;

[0016] Preferably, the cooling component includes a collection tank, the collection tank is opened on the top of the workbench, the top of the inner side of the collection tank is fixedly connected to a filter screen, the inner side of the collection tank is fixedly connected to a water pump, the output end of the water pump is fixedly connected to a connecting pipe, the top of the workbench is fixedly connected to a spray rack, both sides of the inner cavity of the spray rack are fixedly connected to mounting racks, the inner side of the mounting rack is fixedly connected to a filtering mechanism, and the bottom of the filtering mechanism is fixedly connected to an end of the connecting pipe away from the water pump;

[0017] When the grinding wheel is grinding the mandrel on the clamping component, the water pump is turned on, and the output end of the water pump sends the coolant stored in the collection tank into the connecting pipe through the output end of the water pump. At the same time, the coolant is sprayed out through the spray rack through the filtering mechanism, thereby cooling the mandrel during the grinding work. At the same time, the sprayed coolant enters the collection tank through the filter screen for storage, so as to facilitate subsequent use.

[0018] Preferably, the filter mechanism includes a filter tube, the side surface of the filter tube is fixedly connected to the inner side of the mounting frame, the bottom of the filter tube is fixedly connected to the top of the connecting tube, the top of the filter tube is fixedly connected to the inner side of the spray frame, the inner side of the filter tube is evenly provided with sliding grooves, the inner side of the filter tube is fixedly connected to a baffle, the bottom of the baffle is fixedly connected to a support rod, the bottom of the support rod is fixedly connected to a support block, the bottom of the support block is fixedly connected to a telescopic rod, the bottom of the telescopic rod is fixedly connected to a moving assembly, a second spring is sleeved on the telescopic rod, the top of the second spring is fixedly connected to the bottom of the support block, and the bottom of the second spring is fixedly connected to the top of the moving plate;

[0019] When the coolant in the collection tank is fed into the spray rack by the water pump, the coolant enters the filter tube through the connecting pipe. At the same time, the coolant is driven by the water pump to move, so that the baffle filters the coolant that passes through. Driven by the coolant, the moving component moves upward in the sliding groove, and then the moving component contacts and moves with the inner wall of the filter tube.

[0020] Preferably, the moving assembly includes a moving plate, the sides of the moving plate are fixedly connected to sliders, the side of the slider away from the moving plate is slidably connected to the inner side of the sliding groove, and the upper and lower sides of the moving plate are fixedly connected to scrapers, and the sides of the scrapers are in contact with the inner wall of the filter tube;

[0021] When the cooling work is completed, by turning off the water pump, the second spring drives the telescopic rod to reset, so that the telescopic rod drives the movable plate to move downward, so that the movable plate moves downward in the sliding groove through the slider, so that the scraper cleans the inner wall of the filter tube and the impurities scraped off fall out of the filter tube, thereby preventing the impurities from remaining inside the filter tube.

[0022] The present invention provides a device for grinding the outer cylindrical surface of a water pump rotor core shaft. It has the following beneficial effects:

[0023] 1. The water pump rotor core shaft cylindrical grinding processing device is provided with a connecting mechanism.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 3 The present invention provides a technical solution: a water pump rotor core shaft cylindrical grinding device, comprising:

[0043] A workbench 1, a clamping component 2 is fixedly connected to the top of the workbench 1, a transmission component 3 is fixedly connected to the side of the workbench 1, and a cooling component 5 is fixedly connected to the side of the workbench 1 away from the transmission component 3;

[0044] A grinding component 4 is used to grind the rotor core shaft of the water pump 54. The grinding component 4 is installed on the transmission component 3;

[0045] See also Figure 1-Figure 4 The grinding component 4 includes a fixed housing 41, the bottom of the fixed housing 41 is connected to the output end of the transmission component 3, and fixed frames 42 are fixedly connected to both sides of the fixed housing 41. A grinding wheel 44 is rotatably connected to the inner side of the fixed frame 42. A motor 43 is fixedly connected to the side of the fixed frame 42. The output end of the motor 43 is fixedly connected to the side of the grinding wheel 44. A connecting mechanism 45 is fixedly connected to the inner side of the fixed housing 41;

[0046] By turning on the motor 43, the output end of the motor 43 drives the grinding wheel 44 to rotate on the fixed frame 42, so that the grinding wheel 44 grinds the core shaft. At the same time, when the grinding wheel 44 rotates, it contacts and moves with the connecting mechanism 45, so that the connecting mechanism 45 performs a slight grinding work on the side of the grinding wheel 44.

[0047] See also Figures 1-6 The connecting mechanism 45 includes a connecting shell 451, the side of the connecting shell 451 is fixedly connected to the inner side of the fixed shell 41, the side of the connecting shell 451 is fixedly connected to a collecting box 452, the side of the collecting box 452 away from the connecting shell 451 is fixedly connected to an aspirator 453, the inner side of the collecting box 452 is fixedly connected to a mesh plate 1 454, the side of the collecting box 452 away from the aspirator 453 is fixedly connected to a mesh plate 2 455, the middle part of the inner side of the connecting shell 451 is rotatably connected to a rotating roller 456, the side protrusions of the rotating roller 456 are in contact with the side of the grinding wheel 44, and the inner side of the connecting shell 451 near the rotating roller 456 is rotatably connected to both sides of the roughening assembly 457;

[0048] When the output end of the motor 43 drives the grinding wheel 44 to rotate on the fixed frame 42, the rotating roller 456 rotates against the grinding wheel 44 through the protrusions on the surface, so that the rotating roller 456 drives the roughening components 457 on both sides to rotate in the opposite direction of the grinding wheel 44, so that the roughening components 457 grind the side surfaces of the grinding wheel 44. At the same time, by turning on the suction machine 453, the suction force generated by the suction machine 453 when it is working will cause the debris and impurities generated during the grinding work of the grinding wheel 44 to enter the collection box 452 through the second screen plate 455 for collection.

[0049] See also Figure 1-Figure 7 The connecting assembly 457 includes a contact shaft 4571, both ends of which are rotatably connected to the inner side of the connecting shell 451. A contact roller 4572 is fixedly connected to the side of the contact shaft 4571. The side of the contact roller 4572 is evenly provided with a clearance groove 4573. The inner side of the clearance groove 4573 contacts the protrusion on the side of the rotating roller 456. The side of the contact roller 4572 away from the clearance groove 4573 is fixedly connected to the extrusion sleeve 4574.

[0050] When the rotating roller 456 rotates along with the grinding wheel 44, the protrusion on the rotating roller 456 comes into contact with the yield groove 4573 on the contact roller 4572. As a result, when the rotating roller 456 and the grinding wheel 44 rotate relative to each other, the rotating roller 456 drives the contact roller 4572 and the grinding wheel 44 to rotate in the opposite direction. As a result, when the grinding wheel 44 grinds the mandrel, the contact roller 4572 drives the extrusion kit 4574 to rotate in the opposite direction to the side surface of the grinding wheel 44, thereby grinding and trimming the side surface of the grinding wheel 44.

[0051] See also Figures 1-8 The extrusion kit 4574 includes an extrusion plate 45741, the side of the extrusion plate 45741 is fixedly connected to the inner side of the contact roller 4572, the side of the extrusion plate 45741 is slidably connected to the connecting block 45742, the side of the connecting block 45742 away from the extrusion plate 45741 is fixedly connected to the side of the grinding block 45744, the two sides of the extrusion plate 45741 close to the connecting block 45742 are slidably connected to the connecting shaft 45743, the other end of the connecting shaft 45743 is fixedly connected to the grinding block 45744, and a first spring 45745 is sleeved on the connecting shaft 45743, one end of the first spring 45745 is fixedly connected to the grinding block 45744, and the other end of the first spring 45745 is fixedly connected to the extrusion plate 45741;

[0052] When the contact roller 4572 is driven by the rotating roller 456 to rotate in the connecting housing 451, the contact roller 4572 drives the grinding block 45744 and the side of the grinding wheel 44 to grind and trim through the connecting block 45742 and the connecting shaft 45743;

[0053] At the same time, when the extrusion force between the grinding block 45744 and the surface of the grinding wheel 44 is greater than the tensile force of the first spring 45745, the first spring 45745 pulls the grinding block 45744 to move toward the extrusion plate 45741 through the connecting shaft 45743, thereby preventing the extrusion force between the grinding block 45744 and the grinding wheel 44 from being too large, which would cause friction damage to the grinding wheel 44 and the grinding block 45744.

[0054] When the grinding wheel 44 is grinding the mandrel, the side of the grinding wheel 44 can be trimmed by the grinding block 45744. This real-time trimming method can promptly remove the worn parts or clogged grinding chips on the side of the grinding wheel 44, maintain the sharpness and shape accuracy of the side of the grinding wheel 44, help improve the grinding performance and processing quality of the grinding wheel 44, and make the grinding accuracy of the mandrel higher.

[0055] See also Figures 1-11 The present invention provides a technical solution: the cooling component 5 includes a collection tank 57, which is opened on the top of the workbench 1, and a filter 51 is fixedly connected to the top of the inner side of the collection tank 57. A water pump 54 is fixedly connected to the inner side of the collection tank 57, and the output end of the water pump 54 is fixedly connected to a connecting pipe 53. A spray rack 52 is fixedly connected to the top of the workbench 1, and mounting racks 55 are fixedly connected to both sides of the inner cavity of the spray rack 52. A filter mechanism 56 is fixedly connected to the inner side of the mounting rack 55, and the bottom of the filter mechanism 56 is fixedly connected to the end of the connecting pipe 53 away from the water pump 54.

[0056] When the grinding wheel 44 is grinding the mandrel on the clamping member 2, the water pump 54 is turned on, and the output end of the water pump 54 delivers the coolant stored in the collection tank 57 to the connecting pipe 53 through the output end of the water pump 54. At the same time, the coolant is sprayed out through the spray rack 52 by the filtering mechanism 56, thereby cooling the mandrel during the grinding operation. At the same time, the sprayed coolant passes through the filter 51 and enters the collection tank 57 for storage, so as to facilitate subsequent use.

[0057] See also Figures 1-12The filtering mechanism 56 includes a filter tube 561, the side of the filter tube 561 is fixedly connected to the inner side of the mounting frame 55, the bottom of the filter tube 561 is fixedly connected to the top of the connecting tube 53, the top of the filter tube 561 is fixedly connected to the inner side of the spray frame 52, and sliding grooves 567 are evenly opened on the inner side of the filter tube 561. A baffle 562 is fixedly connected to the inner side of the filter tube 561, and the bottom of the baffle 562 is fixedly connected to the support rod 563, and the bottom of the support rod 563 is fixedly connected to the support block 564. The bottom of the support block 564 is fixedly connected to the telescopic rod 565, and the bottom of the telescopic rod 565 is fixedly connected to the moving assembly 568. A second spring 566 is sleeved on the telescopic rod 565, and the top of the second spring 566 is fixedly connected to the bottom of the support block 564, and the bottom of the second spring 566 is fixedly connected to the top of the moving plate 5681;

[0058] When the coolant in the collection tank 57 is fed into the spray rack 52 by the water pump 54, the coolant enters the filter tube 561 through the connecting pipe 53. At the same time, the coolant is driven by the water pump 54 to move, so that the baffle 562 filters the coolant that has passed through. Driven by the coolant, the moving assembly 568 moves upward in the sliding groove 567, and then the moving assembly 568 contacts and moves with the inner wall of the filter tube 561.

[0059] See also Figures 1-13 The moving assembly 568 includes a moving plate 5681, and the sides of the moving plate 5681 are fixedly connected to sliders 5682. The side of the slider 5682 away from the moving plate 5681 is slidably connected to the inner side of the sliding groove 567. The upper and lower sides of the moving plate 5681 are fixedly connected to scrapers 5683. The sides of the scrapers 5683 are in contact with the inner wall of the filter tube 561.

[0060] The coolant in the collection tank 57 is continuously transported to the filter tube 561 through the connecting pipe 53 by the water pump 54. The movement of the coolant causes the movable plate 5681 to move upward in the sliding groove 567 via the slider 5682, and at the same time, the telescopic rod 565 and the second spring 566 are squeezed. The coolant entering the filter tube 561 is filtered by the movable plate 5681. At the same time, scrapers 5683 are provided on the upper and lower sides of the movable plate 5681. When the movable plate 5681 moves upward, the scrapers 5683 can be driven by the movable plate 5681 to contact and move with the inner wall of the filter tube 561.

[0061] When the cooling work is completed, by turning off the water pump 54, the second spring 566 drives the telescopic rod 565 to reset, so that the telescopic rod 565 drives the movable plate 5681 to move downward, so that the movable plate 5681 moves downward in the sliding groove 567 through the slider 5682, so that the scraper 5683 cleans the impurities scraped off the inner wall of the filter tube 561 and drops them out of the filter tube 561, thereby preventing the impurities from remaining inside the filter tube 561.

[0062] Specific workflow:

[0063] The water pump rotor core shaft is installed on the clamping component 2 of the workbench 1. According to the size of the core shaft and processing requirements, the stroke and feed rate of the transmission component 3 and the speed of the grinding component 4 are adjusted;

[0064] Start the grinding component 4 and make it rotate at the set speed. The workbench 1 drives the mandrel to make longitudinal feed motion. At the same time, the grinding wheel 44 is driven by the transmission component 3 to make transverse feed motion to perform rough grinding on the outer circle of the mandrel. At the same time, the cooling component 5 is turned on to cool the mandrel during the grinding operation.

[0065] After rough grinding close to the final size of the mandrel, fine grinding is performed. During fine grinding, the transverse feed of the grinding wheel 44 and the longitudinal feed of the workbench 1 are appropriately reduced, and the grinding speed is increased to obtain higher dimensional accuracy and surface quality;

[0066] After the grinding process is completed, close the workbench 1, wait until the grinding component 4 stops working completely, disassemble the mandrel, carefully remove it and properly place it to avoid damaging the processed surface.

[0067] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
