[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The basic structure of a bearing consists of four parts: an inner ring, an outer ring, a rolling element, and a cage.

[0030] See also Figure 3 and Figure 4 A cylindrical pin 609 is fixedly embedded at the center of the lower end of the arc-shaped clamping plate 607, and the cylindrical pin 609 is located in the limiting straight groove 605 and the arc-shaped driving groove 606. The cylindrical pin 609 is slidingly connected to the limiting disk 603 and the adjusting disk 604 through the limiting straight groove 605 and the arc-shaped driving groove 606 respectively. The lower end of the cylindrical pin 609 is located at the lower side of the limiting disk 603 and is fixedly connected with the limiting plate 610. A positioning shaft 611 passes through the center of the adjusting disk 604, and the connection between the positioning shaft 611 and the adjusting disk 604 is a fixed connection. The positioning shaft 611 is rotatably connected to the limiting disk 603 through a first bearing 612.

[0031] See also Figure 1 and Figure 4 The lower end of the positioning shaft 611 is located inside the hollow base 601 and a driving structure 7 is installed therein. The driving structure 7 includes a turbine 701 fixedly sleeved on the outside of the positioning shaft 611. A worm 702 is installed on the outside of the turbine 701. Both ends of the worm 702 are located on the outside of the hollow base 601 and gears 703 are installed thereon. Two symmetrically distributed first racks 704 and two symmetrically distributed second racks 705 are fixedly installed on the upper end of the machine base 1.

[0032] See also Figure 1 and Figure 4 The second rack 705 is located on the left side of the first rack 704, the first rack 704 is located on the upper side of the gear 703, and the connection between the first rack 704 and the gear 703 is a meshing connection.

The worm 702 is rotatably connected to the hollow base 601 through the second bearing 706.

[0033] The working principle that can improve the bearing processing efficiency: the user first places the assembled bearing body 10 between several groups of arc-shaped clamping plates 607 on the limiting plate 603, and then the transmission mechanism 2 moves the clamping structure 6 and the bearing body 10 to the left. When the gear 703 moves to the first rack 704 and meshes with the first rack 704, the first rack 704 can drive the gear 703 and the worm 702 to rotate clockwise during the movement of the gear 703. The clockwise rotation of the worm 702 drives the turbine 701 and the adjusting plate 604 to rotate. During the rotation, the adjusting plate 604 drives the cylindrical pin 609 and the arc-shaped clamping plate 607 to approach the bearing body 10 through the arc-shaped driving groove 606 until the rubber pad 608 on the arc-shaped clamping plate 607 fits with the outer wall of the bearing body 10, which is conducive to positioning the bearing body 10 to the center on the limiting plate 603. The center is located at the center, which is conducive to the accurate positioning of the oil injection structure 9 between the inner ring and the outer ring of the bearing body 10. After the bearing body 10 moves to the bottom of the oil injection structure 9 and the oil injection is completed, the transmission mechanism 2 transmits the clamping structure 6 and the bearing body 10 to the second rack 705. After the gear 703 and the second rack 705 are meshed with each other, the second rack 705 can drive the gear 703 and the worm 702 to rotate counterclockwise during the movement of the gear 703. The counterclockwise rotation of the worm 702 drives the turbine 701 to rotate in the opposite direction. At this time, several groups of arc clamping plates 607 are gradually moved away from the bearing body 10 under the drive of the adjusting disk 604, which makes it convenient for the staff to pick up the bearing body 10. Through the arrangement of the clamping structure 6 and the driving structure 7, the staff only needs to pick up and place the bearing body 10, which reduces the workload of the staff and improves the efficiency of bearing processing.

[0034] Embodiment 2

[0035] See also Figure 6 This embodiment further explains Example 1. A connecting assembly 8 is installed between the gear 703 and the worm 702. The connecting assembly 8 includes a connecting shaft 801 fixedly installed at both ends of the worm 702. The outer side of the connecting shaft 801 is fixedly sleeved with limit rings 802 near its two ends. The outer side of the connecting shaft 801 is located between the two limit rings 802 and is movably sleeved with a ring 803, and the gear 703 is fixedly sleeved on the outer side of the ring 803. The interior of the ring 803 is movably embedded with a plurality of groups of top beads 804 distributed equidistantly around the circumference.

[0036] See also Figure 7 The top ball 804 can move inside the ring 803. The top ball 804 is located inside the ring 803 and one end thereof is fixedly installed with a spring 805. The end of the spring 805 away from the top ball 804 is fixedly connected to the ring 803. The outer side of the connecting shaft 801 is located between the two limit rings 802 and is provided with spherical grooves 806 equal to the number of the top balls 804. The top ball 804 is movably connected to the connecting shaft 801 through the spherical grooves 806.

[0037] In this embodiment: when the bearing body 10 that needs to be oiled is large in volume, during the process of the first rack 704 driving the gear 703 to rotate and causing the plurality of arc-shaped clamping plates 607 to clamp the bearing body 10, the plurality of arc-shaped clamping plates 607 will clamp the outer wall of the bearing body 10 in advance, while the gear 703 is still meshed with the first rack 704. At this time, the gear 703 and the collar 803 will rotate on the connecting shaft 801 under the action of the inner ring until the gear 703 is separated from the first rack 704. When the gear 703 moves to the second rack 705, the second rack 705 will rotate while driving the gear 703 to rotate, and the top ball 804 will be re-engaged under the drive of the spring 805. Embedded in the spherical groove 806 on the connecting shaft 801, when the second rack 705 drives the gear 703 to rotate in the opposite direction, the worm 702 can rotate together with the gear 703 under the action of several groups of top balls 804. Similarly, when the worm 702 quickly drives several groups of arc clamping plates 607 to move to the maximum distance from the center of the limit plate 603, the second rack 705 will drive the gear 703 and the ring 803 to rotate on the connecting shaft 801. By arranging the gear 703 to be connected to the worm 702 through the connecting assembly 8, the clamping structure 6 can clamp bearing bodies 10 of different sizes, thereby effectively expanding the scope of use of the device.

[0038] Embodiment 3

[0039] See also Figure 8This embodiment further explains other embodiments, the oil injection structure 9 includes a disc 901 installed on the lower side of the first interface 5, a second interface 902 is fixedly installed at the center of the upper end of the disc 901, and the connection between the second interface 902 and the first interface 5 is a threaded connection, a plurality of groups of oil injection nozzles 903 equidistantly distributed in a circle are fixedly installed at the lower end of the disc 901, a ball 904 is movably embedded at the center of the lower end of the oil injection nozzle 903, a cavity 905 is provided inside the disc 901, and cylindrical through grooves 906 are provided inside the oil injection nozzle 903 on both sides of the ball 904, and the cylindrical through grooves 906 and the cavity 905 are communicated with each other.

[0040] In this embodiment: since the second interface 902 is threadedly connected to the first interface 5, when oiling bearing bodies 10 of different models, the user can replace different oiling structures 9 according to the model of the bearing body 10. When the cylinder 4 drives the oiling structure 9 to move downward to inject oil between the inner ring and the outer ring of the bearing body 10, the ball 904 at the lower end of the oiling nozzle 903 will contact the roller in the bearing body 10, and when continuing to move downward, it can drive the roller to revolve between the inner ring and the outer ring of the bearing body 10, so that the oiling nozzle 903 is located at the retaining frame between the rollers, so that the grease can be distributed between the rollers and the retaining frame, and since the oiling nozzle 903 contacts the rollers through the ball 904, it can effectively avoid the oiling nozzle 903 causing wear to the rollers. When the oiling nozzle 903 is inserted between the inner ring and the outer ring of the bearing body 10, the pumping mechanism sends a certain amount of relatively thick grease into the oiling structure 9 through the conduit 11, and the grease is ejected through the cylindrical through groove 906 on the oiling nozzle 903.
