DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 4 , the utility model provides an embodiment: a precision bearing assembly device, including a box body 1, an L-shaped plate 2 is fixedly connected to the top rear side of the box body 1, a cylinder 3 is fixedly connected to the bottom of the L-shaped plate 2, an extrusion plate 4 is fixedly connected to the output end of the cylinder 3, a support plate 28 is fixedly connected to the inside of the box body 1, a support plate 29 is fixedly connected to the upper side of the inside of the box body 1, a round table 27 is rotatably connected to the top of the support plate 29, a rotating disk 23 is fixedly connected to the top of the round table 27, a gear ring 25 is fixedly connected to the outside of the rotating disk 23, a motor 26 is fixedly connected to the top of the support plate 28, a connecting rod 24 is fixedly connected to the output end of the motor 26, a gear 22 is fixedly connected to the top of the connecting rod 24, and the gear 22 is meshed with the gear ring 25. , a disc 9 is fixedly connected to the top of the rotating disk 23, a plurality of assembly grooves 10 are opened inside the disc 9, a push plate 8 is slidably connected inside the assembly groove 10, a plurality of arc plates 11 are fixedly connected to the top of the disc 9, two vertical plates 30 are fixedly connected to the top of the support plate 28, a rack 6 is slidably connected inside the vertical plate 30, a protective shell 31 is fixedly connected to the outside of the vertical plate 30, a connecting rod 2 32 is rotatably connected inside the protective shell 31, a motor 2 34 is fixedly connected to one side of the protective shell 31, a connecting rod 2 32 is fixedly connected to the output end of the motor 2 34, two gears 2 33 are fixedly connected to the outside of the connecting rod 2 32, the gear 2 33 is meshed with the rack 6, and two clamping mechanisms are provided on the top of the box body 1, which are used to clamp the bearing.

[0032] Specifically, when assembling the bearing, first place the bearing to be installed in the designated assembly slot 10 and use the clamping mechanism to stabilize it. After the assembly is completed, start the cylinder 3 to drive the extrusion plate 4 downward to apply pressure to tighten the bearing to prevent it from falling apart due to its loose internal structure and needing to be reinstalled. When the tightening is completed, the cylinder 3 will lift the extrusion plate 4 again to release the clamping, and then the drive motor 1 26 will start, driving the connecting rod 1 24 to rotate, driving the gear 1 22, and further causing the gear ring 25 and the gear 1 22 to rotate, thereby driving the disc 9 to convert. At the same time, the round table 27 cooperates with the movement of the support plate 2 29, making it difficult to remove the bearing. At this time, switch to the drive motor 2 34, which drives the gear 2 33 to rotate, and then drives the rack 6 to move upward, and the push plate 8 also moves up in the assembly slot 10, thereby easily lifting the bearing. In this way, it is convenient to remove the assembled bearings without affecting the continuous assembly of other bearings, thereby improving the overall work efficiency.

[0033] Reference Figure 1 and Figure 2 The clamping mechanism includes a U-shaped plate 12, the bottom of the U-shaped plate 12 is fixedly connected to the top of the box body 1, and two connecting blocks 19 are fixedly connected to the middle side of the bottom of the U-shaped plate 12. A worm 18 is rotatably connected inside the connecting block 19, and a connecting shaft 13 is rotatably connected to the middle side of the U-shaped plate 12. One end of the connecting shaft 13 is fixedly connected to a turntable 15, and the other end of the U-shaped plate 12 is rotatably connected to a worm gear 20. The top of the turntable 15 is fixedly connected to a rotating shaft 14, and a hollow shell 17 is slidably connected to the outside of the rotating shaft 14. The outer side of the hollow shell 17 is slidably connected to the upper side of the inside of the U-shaped plate 12, and the worm gear 20 is meshed with the worm 18. A connecting rod 16 is fixedly connected to one side of the hollow shell 17, and one end of the connecting rod 16 is fixedly connected to an arc-shaped plate 21.

[0034] Specifically, by operating the worm 18, its rotation triggers the corresponding rotation of the worm wheel 20. This series of chain reactions continues to be transmitted, causing the connecting shaft 13 to rotate accordingly. As the connecting shaft 13 rotates, the turntable 15 also rotates, thereby driving the rotating shaft 14 to rotate synchronously. During this process, the rotating shaft 14 slides smoothly inside the hollow shell 17, driving the hollow shell 17 to move accordingly inside the U-shaped plate 12. This movement further prompts the connecting rod 16 to slide accordingly, and then drives the arc plate 2 21 to approach its corresponding arc plate 11. When the two are close, the bearing is firmly fixed between the arc plate 11 and the U-shaped plate 12, forming an ideal assembly position, making the entire assembly process more convenient.

[0035] Reference Figure 1 - Figure 4, a plurality of support columns 7 are fixedly connected to the bottom of the box body 1, and a non-slip pad is fixedly connected to the bottom of the support column 7. Two doors 5 are provided on the front side of the box body 1, and a handle is fixedly connected to the front side of the door 5. The bottom of the arc-shaped plate 21 is slidably connected to the top of the disc 9, the outer side of the rack 6 is slidably connected to the inside of the rotating disc 23, and the outer side of the rotating disc 23 is rotatably connected to the inside of the box body 1, the outer side of the rack 6 is slidably connected to the inside of the disc 9, and the outer side of the rack 6 is slidably connected to the inside of the box body 1.

[0036] Specifically, a plurality of support columns 7 are fixed to the bottom of the housing 1, which are equipped with anti-slip pads to provide stable support. Two doors 5 are provided on the front side of the housing 1, and handles are installed on the doors for easy opening and closing. The bottom of the second curved plate 21 is connected to the top of the disc 9, achieving flexible sliding and facilitating the positioning of the bearing. The outer side of the rack 6 is slidably connected to the inside of the rotating disc 23 and the inside of the disc 9, which makes the movement of the rack 6 smoother. At the same time, the rotating disc 23 can be rotatably connected to the inside of the housing 1 on the outside, playing a supporting role.

[0037] Working principle: When the bearing needs to be assembled, the bearing to be assembled is placed in the corresponding assembly groove 10, and the worm 18 is rotated to rotate, thereby driving the worm wheel 20 to rotate, so that the connecting shaft 13 rotates, and then driving the turntable 15 to rotate, thereby driving the rotating shaft 14 to rotate while sliding inside the hollow shell 17, and then driving the hollow shell 17 to slide inside the U-shaped plate 12, and then driving the connecting rod 16 to slide, and then driving the arc plate 2 21 to move closer to the corresponding arc plate 1 11, and fix the bearing between the arc plate 11 and the U-shaped plate 12, so as to facilitate assembly. When the assembly is completed, start the cylinder 3 to drive the extrusion plate 4 to move downward to extrude and tighten the assembled bearing to avoid directly removing the bearing after assembly, because its internal structure is relatively loose, and it is easy for some parts to fall apart. , it needs to be reassembled. After the extrusion is completed, the cylinder 3 is started to drive the extrusion plate 4 to move upward, and then the clamping mechanism releases the limit on the bearing, and the driving motor 1 26 is started to drive the connecting rod 1 24 to rotate, and then drive the gear 1 22 to rotate, thereby driving the gear ring 25 to rotate, driving the gear 1 22 to rotate, and then drive the disc 9 to convert, and at the same time the frustum 27 rotates on the support plate 2 29. At this time, it is convenient to place the assembled bearing inside the assembly groove 10, which is difficult to remove. At this time, the driving motor 2 34 is driven to drive the gear 2 33 to rotate, and then drive the rack 6 to move upward, and then push the push plate 8 to move upward inside the assembly groove 10, and then push the bearing to move upward. At this time, the assembled bearing can be easily removed. At the same time, the other two sets of bearings can still be assembled, which is beneficial to improve assembly efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
