DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below 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.

[0016] As shown by Figures 1 to 4 the present utility model includes a device base 1. On one side of the top of the device base 1, a first vertical plate 2 is fixedly installed. On the top of the first vertical plate 2, a top plate 3 is fixedly installed. On one side of the bottom of the top plate 3, an electric telescopic cylinder 4 is installed. At the end of the telescopic end of the electric telescopic cylinder 4, a mounting plate 5 is fixedly installed. On one side of the bottom of the mounting plate 5, a pressing module 6 is fixedly installed. On the other side of the top of the device base 1, four movable and adjustable cross-centering adjustment blocks 7 are annularly and equidistantly installed. There is a bearing 8 between the four cross-centering adjustment blocks 7. The bearing 8 is located directly below the pressing module 6. Inside the upper part of the device base 1, a circular groove 9 is opened. Inside the circular groove 9, a disc 10 is rotatably connected. On the top of the disc 10, four adjustment inclined grooves 11 are opened. On the top of the device base 1, four sliding grooves 12 are annularly and equidistantly opened. All four cross-centering adjustment blocks 7 are located inside the circular groove 9, and the lower parts of the four cross-centering adjustment blocks 7 are respectively located inside the four adjustment inclined grooves 11. The upper parts of the four cross-centering adjustment blocks 7 are respectively located inside the four sliding grooves 12 and are in contact with the surface of the bearing 8, so as to effectively center and align the bearing 8 and fix it.

[0017] When the disc 10 rotates, it will drive the four adjustment inclined grooves 11 to rotate. The rotation of the four adjustment inclined grooves 11 will drive the four cross-centering adjustment blocks 7 to move towards the bearing 8 through the four sliding grooves 12, so that the four cross-centering adjustment blocks 7 push and move the bearing 8 and clamp and fix it, so that the bearing 8 moves directly below the pressing module 6. ;

[0018] Inside the middle part of the device base 1, a transmission cavity 13 is opened directly below the circular groove 9. The connecting shaft at the center of the disc 10 extends to directly below the transmission cavity 13 and is fixedly connected with a worm gear 14. Inside the transmission cavity 13, a worm 15 that meshes with the worm gear 14 is rotatably connected. On the top of the device base 1, a vertical groove 16 is opened. One end of the worm 15 extends into the vertical groove 16 and is fixedly connected with a gear 17, so as to effectively perform transmission. On one side of the first vertical plate 2, a vertical sliding groove 18 is opened. Inside the vertical sliding groove 18, a sliding rod 19 is fixedly installed. On the surface of the sliding rod 19, a slider 20 is installed. One end of the mounting plate 5 is fixedly connected with the slider 20. On the bottom of the mounting plate 5, a second vertical plate 21 located inside the vertical groove 16 is fixedly installed. At the lower part of the second vertical plate 21, a transmission rack 22 is fixedly installed. The transmission rack 22 is in transmission connection with the gear 17, so as to effectively perform adjustment.

[0019] During processing, place the bearing on the top of the device base 1 and between the four cross-centering adjustment blocks 7. Then place the sealing ring between the inner ring and the outer ring of the bearing. Then start the electric telescopic cylinder 4, so that the electric telescopic cylinder 4 extends and moves downward to push the mounting plate 5 and the press-fitting module 6 to move downward. The downward movement of the mounting plate 5 will drive the vertical plate two 21 and the transmission rack 22 to move downward, so that the transmission rack 22 drives the gear 17 to rotate. The rotation of the gear 17 will drive the worm 15 to rotate. The rotation of the worm 15 will drive the worm gear 14 to rotate. The rotation of the worm gear 14 will drive the disc 10 to rotate. Finally, the four cross-centering adjustment blocks 7 will push and move the bearing 8 and clamp and fix it, so that the bearing 8 moves to directly below the press-fitting module 6. After that, the transmission rack 22 is separated from the gear 17;

[0020] As the electric telescopic cylinder 4 continues to move downward, the press-fitting module 6 will press-fit the sealing ring between the inner ring and the outer ring of the bearing for sealing; then change the direction of the bearing and perform the press-fitting operation of the sealing ring on the other end again.

[0021] The press-fitting device for the bearing sealing ring can automatically perform the centering alignment operation and the sealing ring press-fitting operation on the bearing, thereby effectively improving the efficiency and speed of bearing processing and being conducive to the batch processing and production of bearings.

[0022] The structure of this press-fitting device is simply designed, easy to use and operate, stable and reliable in processing and adjustment, and its performance can meet the usage requirements of bearing sealing ring processing.
