Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, in particular to a bearing assembly tool. Background Art

[0002] A bearing is a mechanical element that supports a rotating shaft and reduces friction between the shaft and the housing. It plays a vital role in many mechanical systems, such as automobiles, motors, wind turbines, industrial machinery, and household appliances. Bearing assembly refers to the process of assembling the various components of a bearing together during the production of the bearing. The bearing assembly tool is a tooling equipment that assists in assembling the bearing. However, the existing bearing assembly tool usually has a clamp on one side to clamp the outer ring and inner ring of the bearing. At this time, the inner ring is at the center of the outer ring, so that the interlayer spacing between the outer ring and the inner ring is consistent and slightly smaller than the ball. The staff then puts the ball between the inner ring and the outer ring. However, it requires more skilled technicians to quickly complete the operation of putting in the ball.

[0003] The implementation of the utility model aims to provide a bearing assembly tool to solve the problems raised in the above background technology. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4A bearing assembly tool comprises a bottom base 1, an outer ring base 2 and an inner ring base 3, and the bottom base 1 is rectangular as a whole, and the interior of the bottom base 1 is hollow. The upper surface of the bottom base 1 is embedded with the outer ring base 2, and the inner side of the outer ring base 2 is provided with an inner ring base 3, and the inner ring base 3 is fixedly connected to the bottom base 1. A clamping plate 6 is provided on the side of the outer ring base 2, and a spring 5 is fixedly connected to one side of the clamping plate 6, and a fixing block 4 is fixedly connected to the other end of the spring 5. A transmission shaft 10 is fixedly connected to the bottom of the outer ring base 2, and a motor 9 is embedded with the bottom of the transmission shaft 10. When the staff uses the device, the staff can place the device on the operating table, and then place the inner ring of the bearing on the surface of the inner ring base 3. After the inner ring is placed, the staff can open the bottom The clamps 6 on both sides of the upper surface of the base 1 are then used to place the outer ring of the bearing on the surface of the outer ring base 2. After placement is completed, the staff can clamp the outer ring of the bearing through the clamps 6 on both sides, and then move the inner ring placed on the surface of the inner ring base 3 to one side of the outer ring, so that the inner ring is attached to the inner side of the outer ring. Through this operation, a relatively large space is formed on the other side of the inner ring away from the inner wall of the outer ring, so that the staff can directly place the ball between the inner ring and the outer ring. After placement is completed, the staff can reset the inner ring and then loosen the clamps 6 on both sides. After the clamps 6 are loosened, the staff can start the motor 9 to make the motor 9 drive the outer ring base 2 to rotate through the transmission shaft 10, so that the balls between the outer ring and the inner ring can be evenly distributed between the outer ring and the inner ring from one side of the interlayer, thereby completing the installation of the balls.

[0027] A button 7 is embedded and connected to the upper surface of the bottom base 1, and a clamping rod 8 is provided on one side of the button 7, and the clamping rod 8 is embedded and connected to the bottom base 1, a connecting frame 13 is fixedly connected to the bottom of the button 7, and a second spring 14 is fixedly connected to the bottom of the connecting frame 13, and a supporting block 12 is fixedly connected to the bottom of the second spring 14, and a supporting rod 11 is fixedly connected to the bottom of the supporting block 12, and a supporting rod 11 is fixedly connected to the bottom of the bottom base 1, so that when the device is actually used, splints 6 are provided on the left and right sides of the outer ring base 2, and the two splints 6 are symmetrically arranged with the outer ring base 2 as the center, and a clamping rod 8 is provided at the bottom of the two splints 6, and the clamping rod 8 is located at the center of the splint 6 as a whole. When the spring 5 is in an extended state, the splint 6 is located at the upper end of the clamping rod 8, and the clamping rod 8 abuts against the bottom of the splint 6. When the staff needs to place an outer ring or start the outer ring on the surface of the outer ring base 2 When the motor 9 rotates the outer ring base 2, the staff can directly move the clamp plate 6 outward to remove the clamp plate 6 from the upper end of the clamp rod 8. After the clamp plate 6 is removed, the clamp rod 8 can rebound upward through the second spring 14 at the bottom, so that the clamp rod 8 rises and presses against the inner side of the clamp plate 6. Through this design, the clamp rod 8 can limit the clamp plate 6 to prevent the clamp plate 6 from rebounding to the outside of the outer ring base 2. Subsequently, when the clamp plate 6 is required to clamp the outer ring on the surface of the outer ring base 2, the staff can press the button 7 to make the button 7 drive the clamp rod 8 to retract downward through the connecting frame 13. At this time, the clamp plate 6 loses the limit of the clamp rod 8, so that the clamp plate 6 can rebound to the outside of the outer ring base 2 through the spring 5. In this process, pressing down the button 7 will drive the connecting frame 13 to press down and squeeze the second spring 14 at the bottom, so that the connecting frame 13 drives the clamp rod 8 to retract to the inner side of the bottom base 1.

[0028] The connecting frame 13 is divided into two parts as a whole, and one part is rectangular and fixedly connected to the button 7, and the other part is L-shaped and fixedly connected to the clamping rod 8. A limit plate is provided at the connection between the bottom of the clamping rod 8 and the connecting frame 13. The limit plate is located inside the bottom base 1 as a whole, and the button 7 is located at the center of the upper surface of the rectangular part. Through this design, the button 7 can evenly transfer the pressing force to the rectangular part of the connecting frame 13 during the pressing process, thereby avoiding the situation where the connecting frame 13 cannot press down the two second springs 14 at the bottom at the same time due to unbalanced force.

[0029] The upper surfaces of the outer ring base 2 and the inner ring base 3 are both provided with rubber friction pads, so that the outer ring base 2 and the inner ring base 3 can enhance the friction between the outer ring and the inner ring on the surface.

[0030] Working principle: When the staff uses this device, the staff can place the device on the operating table, and then place the inner ring of the bearing on the surface of the inner ring base 3. After the inner ring is placed, the staff can open the clamps 6 on both sides of the upper surface of the bottom base 1, and then place the outer ring of the bearing on the surface of the outer ring base 2. After the placement is completed, the staff can clamp the outer ring of the bearing through the clamps 6 on both sides, and then move the inner ring placed on the surface of the inner ring base 3 to one side of the outer ring so that the inner ring is attached to the inner side of the outer ring. Through this operation, the other side of the inner ring is away from the inner wall of the outer ring to form a relatively large space, so that the staff can directly put the ball between the inner ring and the outer ring. After the placement is completed, the staff can reset the inner ring and then loosen the clamps 6 on both sides. After the clamps 6 are loosened, the staff can start the motor 9, so that the motor 9 drives the outer ring base 2 to rotate through the transmission shaft 10, so that the balls between the outer ring and the inner ring can be evenly distributed between the outer ring and the inner ring from one side of the interlayer, thereby completing the installation of the balls.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0032] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
