Description

Technical Field

[0001] The present invention relates to the technical field of water pump mandrel grinding, and particularly to an outer circle grinding processing device for a water pump rotor mandrel. Background Art

[0002] For the rotor used to drive the impeller rotation in the water pump, its coil is fixed on the mandrel. The output efficiency of the rotor rotation is closely related to the smoothness of the outer circle surface of the mandrel. The outer circle of the mandrel with high smoothness can reduce frictional losses, improve the rotation efficiency of the rotor, and thus enhance the overall performance of the water pump. Therefore, in actual production, it is necessary to perform high-precision grinding on the outer circle of the water pump rotor mandrel to achieve the required surface quality and dimensional accuracy.

[0003] The outer circle grinding processing method often uses the workpiece to be installed on the chuck of the workpiece spindle and rotate in contact with the high-speed rotating grinding wheel for grinding. During the grinding process, the side of the grinding wheel contacts the workpiece, continuously cutting the workpiece material, and the grinding wheel itself will gradually wear. This will cause the abrasive grains on the side of the grinding wheel to gradually become dull and the cutting ability to decline, thereby affecting the grinding efficiency and processing quality. Since the wear degrees of different parts on the side of the grinding wheel may not be the same, after long-term grinding, the shape of the side of the grinding wheel will change and no longer maintain the initial regular shape. This will affect the contact state between the grinding wheel and the workpiece and lead to a decrease in grinding accuracy. Summary of the Invention

[0004] To achieve the above object, the present invention is realized through the following technical solutions: An outer circle grinding processing device for a water pump rotor mandrel, comprising:

[0005] A workbench, 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 for grinding the water pump rotor mandrel, 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 with fixed frames, a grinding wheel is rotatably connected to the inner side of the fixed frames, a motor is fixedly connected to the side of the fixed frames, the output end of the motor is fixedly connected to the side of the grinding wheel, and a connection mechanism is fixedly connected to the inner side of the fixed housing;

[0008] By starting 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 mandrel. At the same time, when the grinding wheel rotates, it contacts and moves with the connection mechanism, so that the connection mechanism performs a micro-grinding operation on the side of the grinding wheel;

[0009] The connecting mechanism includes a connecting shell, the side of the connecting shell is fixedly connected to the inner side of the fixed shell, the side of the connecting shell is fixedly connected to a collecting box, the side of the collecting box away from the connecting shell is fixedly connected to an air suction machine, the inner side of the collecting box is fixedly connected to a mesh plate 1, the side of the collecting box away from the air suction machine is fixedly connected to a mesh plate 2, the middle part of the inner side of the connecting shell is rotatably connected to a rotating roller, the side protrusions of the rotating roller are in contact with the side of the grinding wheel, and both sides of the inner side of the connecting shell close to the rotating roller are rotatably connected to a roughing 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, by turning on the suction machine, the suction force generated by the suction machine when working will collect the debris and impurities generated by the grinding wheel into the collection box through the second screen plate for collection.

[0011] Preferably, the connecting assembly comprises 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 a clearance groove is evenly opened on the side of the contact roller, the inner side of the clearance groove contacts the convex block on the side of the rotating roller, and an extrusion kit is fixedly connected to the side of the contact roller away from the clearance groove;

[0012] When the rotating roller rotates along with the grinding wheel, the convex block on the rotating roller contacts the giving 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 extrusion kit can be driven by the contact roller 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 comprises 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;

[0015] Meanwhile, when the extrusion force between the grinding block and the surface of the grinding wheel is greater than the tensile force of the first spring, the first spring pulls the grinding block, and the grinding block moves axially through the connecting rod to press the extrusion plate, so as to avoid excessive extrusion force between the grinding block and the grinding wheel, which may cause frictional damage to the grinding wheel and the grinding block;

[0016] Preferably, the cooling component includes a collection tank, which is opened at the top of the workbench. A filter screen is fixedly connected to the top inside the collection tank.

A filtering mechanism is fixedly connected to the inside of the mounting rack. The bottom of the filtering mechanism is fixedly connected to the end of the connecting pipe away from the water pump;

[0017] When the grinding wheel grinds the mandrel on the clamping component, by turning on the water pump, 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, through the filtering mechanism, the coolant is sprayed out through the spraying rack, so as to cool 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 filtering mechanism includes a filtering pipe, the side of the filtering pipe is fixedly connected to the inside of the mounting rack, the bottom of the filtering pipe is fixedly connected to the top of the connecting pipe, the top of the filtering pipe is fixedly connected to the inside of the spraying rack, sliding grooves are evenly opened inside the filtering pipe, a baffle is fixedly connected to the inside of the filtering pipe, a support rod is fixedly connected to the bottom of the baffle, a support block is fixedly connected to the bottom of the support rod, a telescopic rod is fixedly connected to the bottom of the support block, a moving component is fixedly connected to the bottom of the telescopic rod, 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 spraying rack by the drive of the water pump, the coolant enters the filtering pipe through the connecting pipe. At the same time, the drive of the water pump by the coolant makes the baffle filter the passing coolant. 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 filtering pipe;

[0020] Preferably, the moving component includes a moving plate, sliders are fixedly connected to the sides of the moving plate, the sides of the sliders away from the moving plate are slidably connected to the inside of the sliding groove, scraping plates are fixedly connected to the upper and lower sides of the moving plate, and the sides of the scraping plates are in contact with the inner wall of the filtering pipe;

[0044] A grinding component 4, which is used for grinding the rotor core shaft of the water pump 54, and the grinding component 4 is installed on the transmission component 3;

[0045] Please refer to Figures 1 - 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, both sides of the fixed housing 41 are fixedly connected with fixed frames 42, a grinding wheel 44 is rotatably connected to the inside of the fixed frames 42, a motor 43 is fixedly connected to the side of the fixed frames 42, the output end of the motor 43 is fixedly connected to the side of the grinding wheel 44, and a connecting mechanism 45 is fixedly connected to the inside 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 micro grinding operation on the side of the grinding wheel 44;

[0047] Please refer to Figures 1 - 6 , the connecting mechanism 45 includes a connecting housing 451, the side of the connecting housing 451 is fixedly connected to the inside of the fixed housing 41, a collection box 452 is fixedly connected to the side of the connecting housing 451, an air suction machine 453 is fixedly connected to the side of the collection box 452 away from the connecting housing 451, a first net plate 454 is fixedly connected to the inside of the collection box 452, a second net plate 455 is fixedly connected to the side of the collection box 452 away from the air suction machine 453, a rotating roller 456 is rotatably connected to the middle of the inside of the connecting housing 451, the convex block on the side of the rotating roller 456 contacts the side of the grinding wheel 44, and two connecting components 457 are rotatably connected to both sides of the inside of the connecting housing 451 close to the rotating roller 456;

[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 by abutting against the grinding wheel 44 through the bumps on its surface, so that the rotating roller 456 drives the connecting components 457 on both sides to rotate in the opposite direction to the grinding wheel 44, so that the connecting components 457 polish the side surface of the grinding wheel 44. At the same time, by turning on the suction machine 453, the suction force generated when the suction machine 453 works is used to suck the debris and impurities generated during the grinding of the grinding wheel 44 through the second mesh plate 455 into the collection box 452 for collection;

[0049] Please refer to Figures 1 - 7 , the connecting component 457 includes a contact shaft 4571. Both ends of the contact shaft 4571 are rotatably connected to the inner side of the connecting housing 451. A contact roller 4572 is fixedly connected to the side surface of the contact shaft 4571. Yielding grooves 4573 are evenly formed on the side surface of the contact roller 4572. The inner side of the yielding groove 4573 is in contact with the bumps on the side surface of the rotating roller 456. A pressing kit 4574 is fixedly connected to the side of the contact roller 4572 away from the yielding groove 4573;

[0050] When the rotating roller 456 rotates following the grinding wheel 44, the bumps on the rotating roller 456 abut against the yielding grooves 4573 on the contact roller 4572. When the rotating roller 456 abuts against and rotates with the grinding wheel 44, the rotating roller 456 drives the contact roller 4572 to rotate in the opposite direction to the grinding wheel 44, so that when the grinding wheel 44 grinds the mandrel, the pressing kit 4574 can be driven by the contact roller 4572 to rotate in the opposite direction to the side surface of the grinding wheel 44, thereby polishing and trimming the side surface of the grinding wheel 44;

[0051] Please refer to Figures 1 - 8 , the pressing kit 4574 includes a pressing plate 45741. The side surface of the pressing plate 45741 is fixedly connected to the inner side of the contact roller 4572.

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 pressing 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 to polish and trim the side surface of the grinding wheel 44 through the connecting block 45742 and the connecting shaft 45743;

[0053] Meanwhile, 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 towards the extrusion plate 45741 through the connecting shaft 45743, thus avoiding excessive extrusion force between the grinding block 45744 and the grinding wheel 44, which may cause frictional damage to the grinding wheel 44 and the grinding block 45744;

[0054] When the grinding wheel 44 grinds the mandrel, the side surface of the grinding wheel 44 can be trimmed by the grinding block 45744.

[0055] Please refer to Figures 1 - 11 The present invention provides a technical solution: The cooling component 5 includes a collection tank 57, the collection tank 57 is opened at the top of the workbench 1, a filter screen 51 is fixedly connected to the top inside the collection tank 57, a water pump 54 is fixedly connected to the inside of the collection tank 57, 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, mounting frames 55 are fixedly connected to both sides inside the cavity of the spray rack 52, a filtering mechanism 56 is fixedly connected to the inside of the mounting frame 55, and the bottom of the filtering mechanism 56 is fixedly connected to one end of the connecting pipe 53 away from the water pump 54;

[0056] When the grinding wheel 44 grinds the mandrel on the clamping component 2, by turning on the water pump 54, the output end of the water pump 54 sends the coolant stored in the collection tank 57 into the connecting pipe 53, and at the same time, through the filtering mechanism 56, the coolant is sprayed out through the spray rack 52, so as to cool the mandrel during the grinding work. At the same time, the sprayed coolant enters the collection tank 57 through the filter screen 51 for storage, so as to facilitate subsequent use;

[0057] Please refer to Figures 1 - 12, the filtering mechanism 56 includes a filter pipe 561. The side of the filter pipe 561 is fixedly connected to the inner side of the mounting frame 55. The bottom of the filter pipe 561 is fixedly connected to the top of the connecting pipe 53. The top of the filter pipe 561 is fixedly connected to the inner side of the spraying frame 52. Sliding grooves 567 are evenly formed in the inner side of the filter pipe 561. A baffle 562 is fixedly connected to the inner side of the filter pipe 561. A support rod 563 is fixedly connected to the bottom of the baffle 562. A support block 564 is fixedly connected to the bottom of the support rod 563. A telescopic rod 565 is fixedly connected to the bottom of the support block 564. A moving assembly 568 is fixedly connected to the bottom of the telescopic rod 565.

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 spraying frame 52 by the drive of the water pump 54, the coolant enters the filter pipe 561 through the connecting pipe 53. At the same time, the movement of the coolant driven by the water pump 54 enables the baffle 562 to filter the passing coolant. Driven by the coolant, the moving assembly 568 moves upward in the sliding groove 567, and then the moving assembly 568 contacts and moves along the inner wall of the filter pipe 561;

[0059] Please refer to Figures 1 - 13 , the moving assembly 568 includes a moving plate 5681. Sliders 5682 are fixedly connected to the sides of the moving plate 5681. The side of the slider 5682 away from the moving plate 5681 is slidably connected to the inner side of the sliding groove 567. Scraping plates 5683 are fixedly connected to both the upper and lower sides of the moving plate 5681. The sides of the scraping plates 5683 are in contact with the inner wall of the filter pipe 561;

[0060] When the coolant in the collection tank 57 is continuously conveyed into the filter pipe 561 through the connecting pipe 53 by the water pump 54, driven by the movement of the coolant, the moving plate 5681 moves upward in the sliding groove 567 through the slider 5682, and at the same time, the telescopic rod 565 and the second spring 566 are squeezed. The moving plate 5681 filters the coolant entering the filter pipe 561. At the same time, since scraping plates 5683 are provided on both the upper and lower sides of the moving plate 5681, when the moving plate 5681 moves upward, it can drive the scraping plates 5683 to contact and move along the inner wall of the filter pipe 561;

[0061] After the cooling operation is completed, by turning off the water pump 54, the second spring 566 drives the telescopic rod 565 to move back, so that the telescopic rod 565 drives the moving plate 5681 to move downward, causing the moving plate 5681 to move downward through the slider 5682 in the sliding groove 567, so that the impurities scraped off the inner wall of the filter tube 561 by the scraper 5683 fall out of the filter tube 561, thus preventing impurities from remaining inside the filter tube 561.

[0062] Specific working process:

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

[0064] Start the grinding component 4 to make the grinding component 4 rotate at the set rotation speed. The workbench 1 drives the core shaft to perform a longitudinal feed movement. At the same time, the grinding wheel 44 makes a transverse feed movement through the drive of the transmission component 3 to rough grind the outer circle of the core shaft. At the same time, by turning on the cooling component 5, cool the core shaft during the grinding operation;

[0065] After the rough grinding is close to the final size of the core shaft, perform fine grinding. During fine grinding, appropriately reduce the transverse feed rate of the grinding wheel 44 and the longitudinal feed rate of the workbench 1, and increase the grinding speed to obtain higher dimensional accuracy and surface quality;

[0066] After the grinding process is completed, turn off the workbench 1. After the grinding component 4 completely stops working, disassemble the core shaft, carefully remove it and place it properly to avoid damaging the machined surface.

The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art unless otherwise specified and limited.
