Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing steel ball processing technology, and in particular to a circulating grinding device for bearing steel ball processing. Background Technology
[0002] Bearing steel balls are the core component of bearings, typically made of high-carbon chromium steel (such as GCr15) or stainless steel, possessing high hardness, wear resistance, and fatigue resistance. Their manufacturing process includes precision techniques such as cold heading, heat treatment, grinding, and polishing to ensure dimensional accuracy, roundness, and surface finish reach micron-level standards. Steel balls are widely used in machinery, automotive, and aerospace industries, supporting rotational motion and reducing friction. High-quality bearing steel balls significantly improve bearing performance and extend service life, making them a key component for the efficient operation of mechanical equipment.
[0003] Traditional grinding equipment is only compatible with steel balls of a fixed size and cannot be used with bearing steel balls of different diameters. When it is necessary to change to steel balls of different specifications, the machine must be stopped and the clamps, grinding disc spacing and pressure parameters must be recalibrated, which is time-consuming and inefficient.
[0004] Therefore, it is necessary to design a circulating grinding device for machining bearing steel balls to solve the above-mentioned technical problems. Utility Model Content
[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a circulating grinding device for processing bearing steel balls.
[0006] The technical solution is as follows: A circulating grinding device for processing bearing steel balls includes a housing, a motor, and a grinding disc. The housing is placed on the ground, and the motor is fixedly connected to the bottom of the housing. The output shaft of the motor passes through the housing and is fixedly connected to the grinding disc. The grinding disc is rotatably connected to the housing. The device also includes a screw, a handwheel, an extrusion disc, a feed pipe, limit rods, a scale, and a collection frame. The upper part of the housing is threadedly connected to the screw, and the top of the screw is fixedly connected to the handwheel. The lower part of the screw passes through the housing and is rotatably connected to the extrusion disc located above the grinding disc. The top of the extrusion disc is connected to and communicates with the feed pipe that exits the housing. Limit rods are fixedly connected to both sides of the top of the extrusion disc, and scales are fixedly connected to the two limit rods in a symmetrical arrangement. A discharge port is opened on the left side of the housing, and a collection frame is placed on the left side of the housing.
[0007] As an improvement to the above solution, it also includes a push plate, a connecting rod, a push rod, and an elastic element. The push plate is slidably connected to one side of the inside of the housing. The right side of the push plate is symmetrically and fixedly connected to a connecting rod that extends out of the housing. The right side of the two connecting rods is fixedly connected to a push rod. The housing and the push rod are symmetrically connected to an elastic element that is wound around the corresponding connecting rod.
[0008] As an improvement to the above solution, the bottom surface of the push plate is flush with the top surface of the grinding disc.
[0009] As an improvement to the above solution, it also includes a blocking block, a pull rod, and a snap-fit rod. A blocking block is slidably placed at the discharge port on one side of the machine housing. Snap-fit holes are symmetrically opened on both sides of the blocking block. A pull rod is fixedly connected to the left side of the blocking block. Snap-fit rods are symmetrically placed on the left side of the machine housing. Both snap-fit rods can be snapped into the corresponding two snap-fit holes.
[0010] As an improvement to the above solution, it also includes a liquid storage tank, a sealing cap, a liquid pump, a telescopic tube, a drain frame, and a drain pipe. The liquid storage tank is fixedly connected to one side of the top of the machine housing. The top of the liquid storage tank is connected to and connected to a water inlet pipe. One end of the water inlet pipe at the top of the liquid storage tank is threadedly connected to a sealing cap. Liquid pumps are symmetrically fixedly connected inside the liquid storage tank. The bottoms of the two liquid pumps are connected to and connected to telescopic tubes that extend out of the liquid storage tank and into the machine housing. The bottoms of the two telescopic tubes are connected to and connected to the extrusion plate. A slot is opened on the left side inside the machine housing. A drain frame is fixedly connected to the slot of the machine housing. A drain pipe is connected to and connected to the front of the drain frame.
[0011] As an improvement to the above solution, a baffle is also included, with a baffle slidably connected to one side of the top of the housing.
[0012] Beneficial effects: 1. This utility model starts the motor, which drives the grinding disc to rotate at high speed, thereby grinding the steel balls. If grinding is required according to different sizes of steel balls, the handwheel is rotated to make the screw rotate and drive the extrusion disc to move up and down. The distance between the extrusion disc and the grinding disc can be adjusted by observing the scale. It can quickly and accurately adapt to the grinding needs of steel balls of different sizes, reduce downtime, and avoid the problem of product quality being affected by excessive or insufficient pressure, thereby improving the quality and consistency of the final product.
[0013] 2. This utility model adds grinding fluid to the storage tank and then pumps the grinding fluid between the extrusion plate and the grinding plate through a liquid pump. The grinding fluid can provide lubrication during the grinding process, reduce the frictional resistance between the steel ball and the grinding plate, thereby reducing energy consumption, accelerating the grinding speed, improving the overall work efficiency, and effectively absorbing and removing the heat, maintaining the temperature of the working area and preventing quality problems caused by overheating.
[0014] 3. By pushing the push rod, the push plate pushes the steel balls on the grinding disc into the collection frame through the connecting rod. This allows the ground steel balls to be moved from the grinding disc to the collection frame quickly and accurately, which can significantly reduce downtime, speed up the entire production process, and improve work efficiency.

[0021] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0022] Example: A circulating grinding device for machining bearing steel balls, such as... Figures 1-5As shown, the assembly includes a housing 1, a motor 2, a grinding disc 3, a screw 4, a handwheel 5, an extrusion disc 6, a feed pipe 7, a limit rod 8, a scale 9, a collection frame 10, and a baffle 22. The housing 1 is placed on the ground. The motor 2 is screwed to the bottom of the housing 1. The output shaft of the motor 2 passes through the housing 1 and is welded to the grinding disc 3. The grinding disc 3 is rotatably connected to the housing 1. When the motor 2 is started, the output shaft of the motor 2 drives the grinding disc 3 to rotate at high speed. Steel balls can be poured onto the grinding disc 3 for grinding. The upper part of the housing 1 is threadedly connected to the screw 4. The top of the screw 4 is welded to the handwheel 5. The lower part of the screw 4 passes through the housing 1 and is rotatably connected to the extrusion disc 6 located directly above the grinding disc 3. The top left side of the extrusion disc 6 is connected to and communicates with the feed pipe 7 that exits the housing 1. Limit rods 8 are welded to the front and rear sides of the top of the extrusion disc 6 to restrict the extrusion disc 6 from sliding up and down in the housing 1. Both limit rods 8 are glued with symmetrically distributed front and back. The scale 9, when the handwheel 5 is rotated, drives the screw 4 to rotate clockwise or counterclockwise, which in turn moves the extrusion plate 6 up or down. During the movement, the height of the extrusion plate 6 can be determined by observing the scale 9. After determining the height, the handwheel 5 is stopped, the screw 4 stops rotating, and the steel balls are poured into the feed pipe 7. The steel balls can flow into the space between the extrusion plate 6 and the grinding plate 3 for grinding. The distance between the extrusion plate 6 and the grinding plate 3 can be adjusted according to the required size of the steel balls to be ground. The left side of the machine housing 1 has a discharge port, and a collection frame 10 is placed on the lower left side of the machine housing 1. The ground steel balls flow out from the discharge port into the collection frame 10. When the collection frame 10 is full, it can be pulled out, the steel balls in the collection frame 10 are cleaned out, and then the collection frame 10 can be placed back in its original position. The top rear side of the machine housing 1 is slidably connected to a baffle 22 to prevent steel balls from falling into the machine housing 1 from the gap between the feed pipe 7 and the machine housing 1.
[0023] like Figure 1 and Figure 4 As shown, it also includes a push plate 11, a connecting rod 12, a push rod 14, and an elastic element 13. The push plate 11 is slidably connected to the right side of the machine housing 1. The bottom surface of the push plate 11 is flush with the top surface of the grinding disc 3. The connecting rods 12, which protrude from the machine housing 1, are symmetrically welded to the front and back of the right side of the push plate 11. The push rod 14 is welded between the right sides of the two connecting rods 12. The elastic element 13, which is a compression spring, is symmetrically connected between the right side of the machine housing 1 and the left side of the push rod 14 and is wound around the corresponding connecting rod 12. The elastic element 13 can be pushed to the left by the operator, and the push plate 11 will also move to the left to push the ground steel ball on the grinding disc 3 into the collection frame 10. At the same time, the elastic element 13 will be squeezed and deformed. When the operator releases the push rod 14, the push plate 11 will slide to the right to its original position under the action of the elastic element 13. If it is necessary to push the ground steel ball into the collection frame 10 again, the above operation can be repeated.
[0024] like Figure 1 and Figure 4 As shown, it also includes a blocking block 15, a pull rod 16, and a locking rod 17. The blocking block 15 is slidably placed at the discharge port on the left side inside the housing 1. The blocking block 15 has locking holes symmetrically opened on both the front and rear sides and the top and bottom. The pull rod 16 is welded to the left side of the blocking block 15. The locking rods 17 are symmetrically placed on the left side of the housing 1. Both locking rods 17 can be locked into the corresponding locking holes. In order to prevent the steel balls from falling off the grinding disc 3 and flowing into the collection frame 10 to the left during grinding, the blocking block 15 can be used to block the steel balls. After the steel balls are ground, the locking rods 17 can be pulled out of the locking holes, and then the pull rod 16 can be pulled to the left to pull the blocking block 15 out of the housing 1. The discharge port is now open and the steel balls can be pushed into the collection frame 10. If the steel balls need to be ground again, the blocking block 15 can be pushed to the right into the housing 1, and then the locking rods 17 can be inserted into the locking holes.
[0025] like Figure 5 As shown, it also includes a liquid storage tank 18, a sealing cap 19, a liquid pump 20, a telescopic pipe 21, a drain frame 2101, and a drain pipe 2102. The liquid storage tank 18 is installed on the top right side of the housing 1 by screws. A water inlet pipe is connected and connected to the middle of the top of the liquid storage tank 18. The top of the water inlet pipe of the liquid storage tank 18 is threadedly connected to the sealing cap 19. The liquid pumps 20 are symmetrically installed inside the liquid storage tank 18 by screws. The bottoms of the two liquid pumps 20 are connected and connected to the telescopic pipes 21 that extend out of the liquid storage tank 18 and into the housing 1. The telescopic pipes 21 can be compressed or stretched at will when the extrusion plate 6 moves up and down. The bottoms of the two telescopic pipes 21 are connected and connected to the extrusion plate 6. The operator first turns clockwise... Open the sealing cap 19 and pour the grinding liquid into the storage tank 18 through the water inlet pipe. When the grinding liquid is full, rotate the sealing cap 19 counterclockwise to close the water inlet pipe of the storage tank 18. Then start the liquid pump 20 to draw the grinding liquid in the storage tank 18 into the telescopic pipe 21 between the extrusion plate 6 and the grinding plate 3, and then inject the grinding medium when grinding the steel ball. A slot is opened on the left side of the inside of the machine housing 1. A drain frame 2101 is installed in the slot of the machine housing 1 by screws. The drain frame 2101 is connected to and connected to the drain pipe 2102. After the steel ball is ground, the grinding liquid is discharged into the drain frame 2101. The external water pipe is connected to the drain pipe 2102 to remove the used grinding liquid in the drain frame 2101.
