Detailed Implementation

[0022] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0023] Example: A rapid grinding device for bearing steel balls, such as... Figures 1-5As shown, the assembly includes a protective frame 1, a first grinding disc 2, a second grinding disc 4, an output shaft 5, a drive motor 6, and a feeding assembly. The first grinding disc 2 is installed on the rear wall inside the protective frame 1. An annular grinding groove 3 is formed inside the first grinding disc 2 to accommodate the steel balls to be ground, providing a specific space for grinding the steel balls. The drive motor 6 is bolted to the front side of the protective frame 1. The output shaft 5 is connected to the drive motor 6 and extends into the interior of the protective frame 1. The second grinding disc 4 is installed on the output shaft 5. The second grinding disc 4 and the output shaft 5 are connected... The output shaft 5 is connected by a sliding snap-fit ​​mechanism, which allows the output shaft 5 to drive the second grinding disc 4 to rotate. At the same time, the second grinding disc 4 can move along the axial direction of the output shaft 5. The second grinding disc 4 is precisely fitted with the first grinding disc 2, and an annular grinding groove 3 is also provided in the second grinding disc 4. The two grinding grooves 3 are aligned with each other and their sizes match, forming the grinding space for the steel ball. The top of both the first grinding disc 2 and the second grinding disc 4 is provided with a semi-circular groove that communicates with the grinding groove 3 for feeding the steel ball. The protective frame 1 is provided with a feeding component to realize the automatic feeding function of the steel ball.

[0024] like Figures 1-5 As shown, the feeding assembly includes a cylinder 7, a protective ring 8, a feeding pipe 9, a first baffle 10, a second baffle 11, and a storage frame 12. The cylinder 7 is bolted to the upper front of the protective frame 1. The telescopic rod of the cylinder 7 extends into the protective frame 1 and is connected to the protective ring 8. The lower end of the protective ring 8 is slidably connected to the lower side of the protective frame 1 via a guide rod, providing additional support for the movement of the protective ring 8 and ensuring its stability. The protective ring 8 is fitted outside the first grinding disc 2 and the second grinding disc 4, and rotates independently with the second grinding disc 4, enabling synchronous movement of both. The feeding pipe 9 is connected to the middle of the top of the protective ring 8, and the feeding pipe 9 is connected to a semi-circular groove. The feed tube 9 is used for feeding steel balls. It can hold at least two steel balls to ensure that a single feeding can meet certain grinding requirements. A first baffle 10 is welded to the upper front side of the inner part of the protective frame 1. The first baffle 10 slides with the feed tube 9. A slot matching the size of the feed tube 9 and communicating with it is opened on the rear side of the first baffle 10. A second baffle 11 is welded to the upper side of the feed tube 9. The second baffle 11 does not block the upper port of the feed tube 9, ensuring that the steel balls can be fed normally through the feed tube 9. A storage frame 12 for storing steel balls is connected to the top of the protective frame 1. The bottom port of the storage frame 12 is initially blocked by the second baffle 11 to ensure that the steel balls inside do not fall out.

[0025] When using this device to grind bearing steel balls, first add the steel balls into the storage box 12. Then, cylinder 7 is activated, controlling its telescopic rod to shorten, causing the protective ring 8 to move forward, which in turn causes the second grinding disc 4 to move forward along the output shaft 5, separating the first grinding disc 2 from the second grinding disc 4. At the same time, the feeding pipe 9 and the second baffle 11 move forward. When the slot on the first baffle 10 is disconnected from the feeding pipe 9 and the upper end of the feeding pipe 9 is aligned with the storage frame 12, the steel balls in the storage frame 12 will fall into the feeding pipe 9. Since the feeding pipe 9 can hold three steel balls, the steel balls in the feeding pipe 9 will not fall into the protective ring 8 due to the obstruction of the first baffle 10. After feeding is completed, the telescopic rod of cylinder 7 is extended, causing the protective ring 8 and the second grinding disc 4 to move backward and reset, which in turn causes the feeding pipe 9 and the second baffle 11 to move backward. When the second baffle 11 moves to block the lower end of the storage frame 12, it can prevent the steel balls in the storage frame 12 from falling further. When the feed tube 9 moves backward and aligns with the slot of the first baffle 10, the two steel balls inside the feed tube 9 will fall downward into the protective ring 8, and then through the semi-circular groove into the grinding groove 3. At this time, the cylinder 7 automatically shuts off, and the drive motor 6 is started. Its output shaft 5 rotates, driving the second grinding disc 4 to rotate. Through the friction between the grinding groove 3 and the steel balls, the steel balls are driven to roll in the groove, thereby achieving uniform grinding of the steel balls. After grinding is completed, the drive motor 6 is turned off, and then the above operation is repeated to drive the second grinding disc 4 to move forward and separate from the first grinding disc 2. The ground steel balls in the grinding groove 3 will then fall downward for subsequent collection. Then, new steel balls are fed in, and the grinding work of steel balls can be carried out continuously by following the above operation.

[0026] like Figures 1-2 As shown, it also includes a filter screen 13 and a feeding frame 14. The filter screen 13 is connected to the lower side of the inner side of the protective frame 1 and is arranged at an angle. The filter screen 13 is located below the first grinding disc 2 and the second grinding disc 4. A discharge chute is opened on the right side wall of the protective frame 1 at the right end of the filter screen 13. The feeding frame 14 located at the discharge chute is connected to the right side of the filter screen 13. After the steel balls are ground, they fall down onto the filter screen 13 and slide down the inclined surface of the filter screen 13 into the feeding frame 14, and are then discharged through the feeding frame 14 for easy collection by the operator.

[0027] like Figures 2-3 As shown, it also includes a spray pipe 15 and a delivery pump 16. The delivery pump 16 is installed at the bottom of the protective frame 1 by bolts. The top of the delivery pump 16 is connected to the spray pipe 15. The spray pipe 15 passes through the filter screen 13. Its upper end is bent at 90 degrees and aligned with the slot of the second baffle 11 and the upper port of the feed pipe 9. The port of the spray pipe 15 and the second baffle 11 are on the same horizontal plane. When the second baffle 11 moves, it can block the port of the spray pipe 15.

[0028] Grinding fluid is stored in the space below the filter screen 13 at the bottom of the protective frame 1. During the grinding of the steel balls, the delivery pump 16 is activated to pump the grinding fluid into the spray pipe 15. The grinding fluid flows through the slot of the second baffle 11 into the feed pipe 9, and then flows into the grinding tank 3 to assist in the grinding of the steel balls. Excess grinding fluid during the grinding process flows directly downward back into the space below the protective frame 1. During this process, the filter screen 13 can filter impurities. When the steel balls are finished grinding, the protective ring 8 moves the second grinding disc 4 forward and separates it from the first grinding disc 2. The ground steel balls fall downward for subsequent collection. At the same time, the forward movement of the protective ring 8 moves the feed pipe 9 and the second baffle 11 forward, causing the slot on the second baffle 11 to disengage from the alignment with the port of the spray pipe 15. At this time, the second baffle 11 will block the port of the spray pipe 15, which can prevent the grinding fluid from continuing to flow out and causing splashing.

They should not be construed as limiting the scope of protection of this utility model.
