However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a bearing assembly extrusion device, including: a base plate 1 and a threaded rod 3, a tooling 11 is arranged at the top center of the base plate 1, a first mounting plate 2 is fixedly connected to the rear surface of the base plate 1, a threaded cylinder 5 is fixedly connected to the inner surface of the first mounting plate 2, a hand wheel 6 is fixedly connected to the outer surface of the threaded rod 3 away from the first mounting plate 2, a second mounting plate 7 is fixedly connected to the front surface of the base plate 1, a cylinder 8 is arranged on the front surface of the second mounting plate 7, and the telescopic end of the cylinder 8 slides through the front surface of the second mounting plate 7; an extrusion component 9, the extrusion component 9 includes a fixed block 901 and a mounting block 902, the fixed block 901 is fixedly connected to the top of the base plate 1 near the rear side of the second mounting plate 7, a fixed shaft 908 is fixedly connected to the top of the mounting block 902 near one side edge, a connecting block 907 is rotatably connected to the outer surface of the fixed shaft 908, and the connecting block 907 is matched with the cylinder 8. The top of the fixed block 901 is fixedly connected to a mounting block 902 at a position away from the connecting block 907, and a cover 906 is fixedly connected to the rear surface of the mounting block 902. A push rod 904 is slidably connected between the cover 906 and the inner surface wall of the mounting block 902. The push rod 904 and the connecting block 907 are matched. The inner surface of the threaded cylinder 5 is threadedly rotatably connected to the threaded rod 3. The outer surface of the threaded rod 3 is provided with a first rubber sleeve 4 away from the hand wheel 6. The outer surface of the push rod 904 is fixedly connected to a push block 909 at a position close to the connecting block 907. The push block 909 is circular. The outer surface of the push rod 904 is sleeved with a spring 903, which is located between the opposite surfaces of the push block 909 and the cover 906. The outer surface of the push rod 904 is provided with a second rubber sleeve 905 near the rear surface of the cover 906. The first rubber sleeve 4 and the second rubber sleeve 905 are on the same horizontal line.

[0023] The effect achieved by the entire embodiment 1 is that when assembling the bearing, first place the outer skin of the bearing in the top groove of the tooling 11 so that the bottom side of the outer skin of the bearing is limited in the groove, the inner core of the bearing is placed on the inner side of the outer skin, and after a proper amount of steel balls are filled between the outer skin and the inner core of the bearing, the first mounting plate 2 is fixed at the center of the rear surface of the base plate 1, and the hand wheel 6 is turned to rotate the threaded rod 3 in the threaded tube 5. The threaded rod 3 will move toward the center of the base plate 1 until the first rubber sleeve 4 arranged on its outside contacts and fixes the outer skin of the bearing. The second mounting plate 7 is fixed on the front surface of the base plate 1 near the left side, and the cylinder 8 arranged on its front surface is started. During the instantaneous extension process, the telescopic end thereof will push the side of the connecting block 907 away from the fixed shaft 908. Using the principle of lever, the connecting block 907 rotates around the fixed shaft 908 as the fulcrum, and its rear side surface is arc-shaped near the middle position. The shape will slide and rub with the front end surface of the push rod 904, forcing the push rod 904 to move backward between the cover 906 and the inner wall of the mounting block 902, and in the process of moving backward, it drives the push block 909 to squeeze the spring 903, causing it to deform and shrink. The second rubber sleeve 905 set on the surface of the push rod 904 will hammer the outer skin of the limited bearing to evenly disperse the steel balls between the outer skin and the inner core of the bearing, and the outer skin and the inner core are compounded to complete the assembly of the bearing. After the telescopic end of the cylinder 8 is reset, the spring 903 squeezes the push block 909 under the elastic reset action, driving the push rod 904 to slide and reset in the mounting block 902, and pushes the connecting block 907 to reset. The first rubber sleeve 4 set on the outer surface of the threaded rod 3 and the second rubber sleeve 905 set on the outer surface of the push rod 904 play a protective role to prevent the bearing surface from being damaged, thereby improving the production quality of the product.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the inner wall of the tooling 11 is equipped with an inner angle bolt 12, which is located at the center of the inner bottom of the tooling 11. An adjustment groove 10 is opened at the top of the base plate 1 near the first mounting plate 2, and the inner angle bolt 12 is matched with the adjustment groove 10.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, the inner angle bolt 12 is screwed to separate the screw thread from the adjusting groove 10, thereby disassembling the tooling 11, and the tooling 11 of the same size can be replaced according to the specifications of the bearing. Moreover, after the tooling 11 is moved laterally on the top of the base plate 1, the inner angle bolt 12 is screwed to fix it with the adjusting groove 10, and the threaded rod 3 moves accordingly with the rotation of the hand wheel 6, so that bearings of different specifications can be assembled, thereby improving the use effect of the bearing assembly extrusion equipment.

[0026] Working principle: When in use, first assemble the bearing according to the specifications required, select the tooling 11 of the same size, place it above the adjusting groove 10 of the bottom plate 1, and adjust the position above the adjusting groove 10 according to the distance between the assembled bearing surface and the push rod 904, then insert the inner angle bolt 12 into the tooling 11, use the tool to rotate the inner angle bolt 12 to make it threadedly connected and fixed with the adjusting groove 10, which plays the role of adjustment, place the outer skin of the bearing in the top groove of the tooling 11, so that the bottom side of the outer skin of the bearing is limited in the groove, the inner core of the bearing is placed on the inner side of the outer skin, and after filling a proper amount of steel balls between the outer skin and the inner core of the bearing, turn the handwheel 6 to rotate the threaded rod 3 in the threaded tube 5, and the threaded rod 3 will move toward the center of the bottom plate 1 until the first rubber set on its outside The sleeve 4 is used to resist and fix the outer skin of the bearing. The cylinder 8 is started. During the instantaneous extension process, the telescopic end thereof will push the side of the connecting block 907 away from the fixed shaft 908. By utilizing the lever principle, the connecting block 907 rotates around the fixed shaft 908 as the fulcrum. The arc-shaped surface on the rear side will slide and rub against the front end surface of the push rod 904, forcing the push rod 904 to slide backward between the cover 906 and the inner wall of the mounting block 902. The second rubber sleeve 905 provided on the rear end face of the push rod 904 will hammer the outer skin of the bearing that is fixed in a limited position, so that the steel balls between the outer skin and the inner core of the bearing are evenly dispersed. No manual hammering is required during the bearing assembly process, which avoids the need for manual hammering for a long time during the assembly of large quantities of bearings, thereby reducing the labor intensity of manual hammering.
