Technical Field

[0001] The utility model relates to the technical field of bearing production, and particularly relates to a precision bearing assembly device. Background Technique

[0002] With the continuous development of China's industry, in mechanical manufacturing, precision bearings are indispensable mechanical equipment parts. Precision bearings are assembled by pressing an outer ring body, terminals, and an inner ring body together, and are suitable for supporting mechanical rotating bodies and reducing the friction coefficient in mechanical motion. The assembly of bearings is to place steel balls between the outer ring and the inner ring of the bearing, and then use a limiting component to fix the relative positions of each steel ball.

[0003] When the traditional bearing assembly equipment puts steel balls between the inner ring and the outer ring of the bearing, it directly opens the control valve below the device to make the steel balls flow out. The steel balls cannot flow out quantitatively, and the operator still needs to check the number of steel balls between the inner ring and the outer ring of the bearing, which affects the assembly efficiency of the bearing. Therefore, a precision bearing assembly device is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a precision bearing assembly device, including a workbench 1, an adjustment tank 2 and a bead storage tank 3. A blanking pipe 4 is fixedly communicated with the outer surface of the bottom of the bead storage tank 3. A connecting pipe 5 is arranged on the outer surface of the bottom of the blanking pipe 4. A motor 6 is fixedly installed on the outer surface of the bottom of the adjustment tank 2. The output end of the motor 6 is fixedly connected with a push rod 7. A fixed pad 13 is fixedly connected with the inner surface of the bottom of the adjustment tank 2. An infrared counter 8 is fixedly installed on the outer surface of the top of the fixed pad 13. A controller is fixedly installed on the outer surface of the top of the workbench 1. Both the infrared counter 8 and the motor 6 are electrically connected to the controller. An outlet pipe 12 is fixedly communicated with the outer surface of the bottom of the adjustment tank 2. In this embodiment, the balls are stored inside the bead storage tank 3, and the balls enter the connecting pipe 5 through the blanking pipe 4. When assembling the steel balls, the motor 6 works. The motor 6 drives the push rod 7 to rotate. Under the action of the push rod 7, the push rod 7 pushes the bottommost ball, so that the bottommost ball is pushed out. Then the ball above the bottommost ball falls to the bottommost. As the push rod 7 rotates, the balls are pushed into the outlet pipe 12 and thus enter the inner and outer rings of the bearing. When the push rod 7 rotates, the infrared counter 8 counts. After reaching a certain value, the infrared counter 8 sends a signal to the controller. The controller receives the signal and makes the motor 6 stop working, so that a specified number of balls can be loaded.

[0023] A telescopic pipe 16 is fixedly communicated with the outer surface of the bottom of the outlet pipe 12. A second electric telescopic rod 15 is fixedly installed on the outer surface of the bottom of the adjustment tank 2. The output end of the second electric telescopic rod 15 is fixedly connected with a fixing plate. The telescopic pipe 16 fixedly penetrates through the outer surface of the fixing plate. In this embodiment, the second electric telescopic rod 15 works. The second electric telescopic rod 15 drives the telescopic pipe 16 to adjust the distance between the bottom of the telescopic pipe 16 and the bearing to an appropriate distance, so as to prevent the balls from popping out due to too high a height when falling.

[0024] A mounting bracket 9 is fixedly connected to the outer surface at the rear side of the workbench 1. A first electric telescopic rod 10 is fixedly installed on the outer surface of the mounting bracket 9. The output end of the first electric telescopic rod 10 is fixedly connected to a push plate 11. In this embodiment, when the first electric telescopic rod 10 is turned on, the first electric telescopic rod 10 drives the push plate 11 to move the inner ring and the outer ring. At this time, the inner ring of the bearing is located at the rear side of the outer ring. After the first electric telescopic rod 10 is pushed to a certain position, it stops working, so that the inner ring and the outer ring of the bearing are located below the telescopic tube 16. After the assembly is completed, the first electric telescopic rod 10 continues to work to push the bearing away from the bottom of the telescopic tube 16.

[0025] A guiding groove 14 is formed on the outer surface of the fixing pad 13. The guiding groove 14 communicates with the discharge pipe 12. In this embodiment, the movement of the balls is limited by setting the guiding groove 14.

[0026] Internal thread teeth are formed on the inner surface of the blanking pipe 4, and external thread teeth are formed on the outer surface of the connecting pipe 5. The blanking pipe 4 is threadedly connected to the connecting pipe 5. In this embodiment, according to the sizes of different balls, the position between the bottom of the connecting pipe 5 and the fixing pad 13 is adjusted so that only one ball can be completely exposed, and two balls cannot be exposed simultaneously.

[0027] The blanking pipe 4 is bent. An elastic member is fixedly connected to the inside of the bent end of the blanking pipe 4. In this embodiment, by setting the elastic member, when the push rod 7 presses the balls, the balls above the bottommost one move upward, and then the balls in contact with the elastic member can cause the elastic member to deform, providing a certain moving space.

[0028] Two support feet are fixedly connected to the outer surface at the bottom of the adjustment tank 2. The other ends of the two support feet are fixedly connected to the outer surface at the top of the workbench 1. In this embodiment, the adjustment tank 2 is supported by the support feet.

[0029] An opening is provided on the outer surface at the left side of the adjustment tank 2. In this embodiment, the position between the connecting pipe 5 and the blanking pipe 4 is adjusted through the opening.

[0030] Working principle: When the utility model is in use, the inner ring of the bearing is placed inside the outer ring and placed on the workbench 1. The first electric telescopic rod 10 is turned on. The first electric telescopic rod 10 drives the push plate 11 to move the inner ring and the outer ring. At this time, the inner ring of the bearing is located behind the outer ring. After the first electric telescopic rod 10 is pushed to a certain position, it stops working, so that the inner ring and the outer ring of the bearing are located below the telescopic tube 16. The second electric telescopic rod 15 works. The second electric telescopic rod 15 drives the telescopic tube 16 to adjust the distance between the bottom of the telescopic tube 16 and the bearing to a suitable distance to prevent the balls from popping out due to too high a height when they fall. The balls are stored inside the ball storage tank 3, and the balls enter the connecting tube 5 through the feeding tube 4. When assembling the steel balls, the motor 6 works. The motor 6 drives the push rod 7 to rotate. Under the action of the push rod 7, the push rod 7 pushes the bottommost ball, so that the bottommost ball is pushed out and enters the guide groove 14. Then the ball above the bottommost ball falls to the bottommost. As the push rod 7 rotates, the balls are pushed into the discharge tube 12 and thus enter the inner ring and the outer ring of the bearing. When the push rod 7 rotates, the infrared counter 8 counts. After reaching a certain value, the infrared counter 8 sends a signal to the controller. The controller receives the signal and makes the motor 6 stop working, so that a specified number of balls can be loaded. After the assembly is completed, the first electric telescopic rod 10 continues to work to push the bearing away from the bottom of the telescopic tube 16.

[0031] The controller is of an existing structure, and the control circuit can be realized by simple programming of those skilled in the art, which belongs to the common knowledge in the field. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
