Description

Technical Field

[0001] The utility model relates to the technical field of bearing ball processing, in particular to a rolling bearing ball polishing device. Background Art

[0002] With the development of society, my country's industrial level has gradually improved. Bearings are used in the mechanical field as a common component, generally in low-load mechanical transmission equipment. However, ball bearings have a small load area. If there are microscopic burrs and other defects on the surface of the ball, it is very easy to cause serious mechanical damage or carbon deposits in the pits under high-speed operation.

[0003] The prior art discloses a bearing ball grinding and polishing device with application number CN202020757722.2. Although the device can grind multiple balls at the same time and achieve good positioning of the balls during use, so it has good practicality, the inner volume of the spherical groove of the device is fixed, which is not convenient for polishing balls of different sizes. After the smaller balls are placed in the spherical groove, only the bottom of the balls are in contact with the polishing pad, and most of the balls are not in contact with the polishing pad. During grinding, the polishing purpose can only be achieved by relying on the rolling of the balls themselves, which will cause low polishing efficiency and uneven polishing. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a rolling bearing ball polishing device to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rolling bearing ball polishing device, comprising a base, a polishing table is provided on the top of the base, a rotating shaft passes through the bottom of the polishing table, a ball groove and a gear are respectively provided at the top and bottom ends of the rotating shaft, a rotating cylinder is installed in the middle of the top of the polishing table through a bearing, and a gear ring is provided on the outer surface of the rotating cylinder, a connecting shaft is provided inside the rotating cylinder, a connecting disk is connected to the top of the connecting shaft, and a rotating ring is connected to the bottom of the connecting disk through a connecting rod, the inner wall of the ball groove is connected to a connecting plate through a telescopic rod and a second spring, and a polishing pad is connected to the connecting plate.

[0006] Furthermore, the inner wall of the rotating drum is provided with a fitting strip, and the outer wall of the connecting shaft is provided with a fitting groove.

[0007] By adopting the above technical solution, under the limiting effect of the fitting strip and the fitting groove, the rotation of the drum can cause the connecting shaft to rotate without affecting the up and down displacement of the connecting shaft.

[0008] Furthermore, the middle of the top and the edge of the polishing table are inclined toward the ball groove.

[0009] By adopting the above technical solution, the inclined setting makes it easier for workers to place the balls, that is, the balls are placed on the inclined part, and the balls roll toward the ball grooves by themselves, making it convenient to discharge the materials.

[0010] Furthermore, a driven rotating wheel is provided below the outer surface of the rotating drum, a motor is installed on one side of the polishing table, the output end of the motor is connected to the driving rotating wheel, and the driving rotating wheel and the driven rotating wheel are matched through a transmission belt.

[0011] By adopting the above technical solution, the motor rotates to rotate the driving wheel, and the driving wheel drives the driven wheel to rotate through the transmission belt, and the driven wheel causes the drum to rotate.

[0012] Furthermore, a first spring is provided on the outer surface of the connecting rod, and the top and bottom of the first spring are respectively connected to the connecting disk and the rotating ring.

[0013] By adopting the above technical solution, under the action of the first spring, the rotating ring can elastically press the ball, so that the rotating ring is always in contact with the ball.

[0014] Furthermore, a mounting plate is connected to the middle of the top of the base via a hydraulic rod, and the bottom end of the connecting shaft is movably connected to the mounting plate.

[0015] By adopting the above technical solution, the hydraulic rod can drive the mounting plate to move up and down, thereby causing the connecting shaft to drive the connecting disk to move up and down, making it easier to take and place the balls.

[0016] Furthermore, an arc-shaped groove is provided at the bottom of the rotating ring, and a rubber pad is provided in the arc-shaped groove.

[0017] By adopting the above technical solution, the arc groove design can fit with the arc surface of the ball, and the rubber pad can increase the friction between the ball and the rubber pad. Therefore, when the rotating ring rotates, multiple balls can rotate at the same time, so that the polishing pad can be used to fully polish the outer surface of the ball.

[0018] Furthermore, the gears are provided in multiple groups, and the multiple groups of gears are all meshed with the gear ring.

[0019] By adopting the above technical solution, the rotation of the gear ring can cause multiple sets of gears to rotate synchronously, thereby causing the rotating shaft to drive the ball groove to rotate in the horizontal direction.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. When placing the ball, the utility model can squeeze the polishing pad due to its certain flexibility under the cooperation of the second spring, the telescopic rod and the connecting plate, so that the polishing pad can be in close contact with the ball, thereby improving the polishing effect and the scope of application, making it easier to polish more balls of different sizes, and having strong practicality.

[0022] 2. During grinding, the utility model drives the mounting plate to move downward by the hydraulic rod, so that the connecting shaft drives the connecting disk to drive the rotating ring to move downward, thereby pressing the rotating ring on the ball, and then starting the motor to rotate the drum. The rotation of the drum drives the connecting shaft to drive the connecting disk and the rotating ring to rotate, thereby driving multiple balls to rotate at the same time, so that the balls rub against the polishing pad. At the same time, the rotation of the drum causes the gear ring to rotate, and the gear ring causes the rotating shaft to rotate through the gear. The rotation of the rotating shaft causes the ball groove to rotate, thereby rotating the polishing pad to polish the balls. The technical solution improves the efficiency of ball polishing through the axial rotation of the balls combined with the horizontal rotation of the polishing pad, makes the ball polishing more uniform, and improves the quality of the balls.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1: A rolling bearing ball polishing device, such as Figure 1-Figure 7 As shown, it includes a base 1, a polishing table 4 is provided on the top of the base 1, a rotating shaft 10 is passed through the bottom of the polishing table 4, a ball groove 11 and a gear 12 are respectively provided at the top and bottom ends of the rotating shaft 10, a rotating cylinder 13 is installed in the middle of the top of the polishing table 4 through a bearing, and a gear ring 18 is provided on the outer surface of the rotating cylinder 13, a connecting shaft 5 is provided inside the rotating cylinder 13, a fitting strip 23 is provided on the inner wall of the rotating cylinder 13, and a fitting groove 24 is provided on the outer wall of the connecting shaft 5. Under the limiting action of the fitting strip 23 and the fitting groove 24, the rotating cylinder 13 can be rotated without affecting the up and down displacement of the connecting shaft 5. 13 rotation can make the connecting shaft 5 rotate, the top of the connecting shaft 5 is connected with the connecting disk 6, the bottom of the connecting disk 6 is connected with the rotating ring 9 through the connecting rod 7, the inner wall of the ball groove 11 is connected with the connecting plate 22 through the telescopic rod 20 and the second spring 21 respectively, and the connecting plate 22 is connected with the polishing pad 19, the top middle of the base 1 is connected with the mounting plate 3 through the hydraulic rod 2, and the bottom end of the connecting shaft 5 is movably connected with the mounting plate 3, the hydraulic rod 2 can drive the mounting plate 3 to move up and down, and then the connecting shaft 5 drives the connecting disk 6 to move up and down, which is convenient for taking and placing the balls.

[0034] See also Figure 1-Figure 2 In the above embodiment, a driven rotating wheel 16 is provided below the outer surface of the rotating drum 13, a motor 14 is installed on one side of the polishing table 4, the output end of the motor 14 is connected to the driving rotating wheel 15, and the driving rotating wheel 15 and the driven rotating wheel 16 are matched through a transmission belt 17. The rotation of the motor 14 causes the driving rotating wheel 15 to rotate, and the driving rotating wheel 15 drives the driven rotating wheel 16 to rotate through the transmission belt, and the driven rotating wheel 16 causes the rotating drum 13 to rotate.

[0035] See also Figure 2 and Figure 4 In the above embodiment, there are multiple groups of gears 12, and the multiple groups of gears 12 are all meshed with the gear ring 18. After the gear ring 18 rotates, the multiple groups of gears 12 can rotate synchronously, thereby causing the rotating shaft 10 to drive the ball groove 11 to rotate horizontally.

[0036] Example 2: See Figure 2The top middle and edge of the polishing table 4 are inclined toward the ball groove 11. The inclined setting is convenient for the staff to place the balls, that is, the balls are placed on the inclined part, and the balls roll toward the ball groove 11 by themselves, making the discharge convenient.

[0037] Example 3: See Figure 1 , Figure 2 and Figure 4 A first spring 8 is provided on the outer surface of the connecting rod 7, and the top and bottom of the first spring 8 are respectively connected to the connecting disk 6 and the rotating ring 9. Under the action of the first spring 8, the rotating ring 9 can elastically press the ball so that the rotating ring 9 is always in contact with the ball.

[0038] Example 4: See Figure 2 An arc groove is provided at the bottom of the rotating ring 9, and a rubber pad is provided in the arc groove. The arc groove is designed to fit the arc surface of the ball, and the rubber pad can increase the friction between the ball and the rubber pad. Therefore, when the rotating ring rotates, multiple balls can rotate at the same time, so that the polishing pad 19 can be used to fully polish the outer surface of the ball.

[0039] The implementation principle of this embodiment is as follows: first, the staff places the ball in the ball groove 11. Under the action of the second spring 21, the polishing pad 19 is in close contact with the ball. Then, the hydraulic rod 2 is started. After the hydraulic rod 2 moves downward, the connecting shaft 5 drives the connecting plate 6 to move downward. After the rotating ring 9 contacts the ball, the connecting plate 6 continues to move downward, thereby making the first spring 8 in a compressed state, so that the ball is in an elastically compressed state. Then, the motor 14 is started to rotate the drum 13. The rotation of the drum 13 drives the connecting shaft 5 to drive the connecting plate 6 to rotate. The rotating ring 9 rotates, and the rotating ring 9 can drive multiple balls to rotate at the same time through the friction force of the rubber pad, so that the balls rub against the polishing pad 19 to achieve the polishing purpose. At the same time, the rotation of the drum 13 causes the gear ring 18 to rotate, and the gear ring 18 rotates the rotating shaft 10 through the gear 12. The rotation of the rotating shaft 10 causes the ball groove 11 to rotate, so that the polishing pad 19 rotates, and the polishing pad 19 rotates to polish the balls synchronously. After polishing is completed, the hydraulic rod 2 causes the connecting plate 6 to move upward. At this time, the staff can absorb the balls from the ball groove 11 through the magnet tool.
