Description

Technical Field

[0001] The utility model relates to the field of needle roller bearings, and particularly relates to a curling device for needle roller bearings. Background Art

[0002] As a key component, the performance and stability of a needle roller bearing are directly related to the operating efficiency and lifespan of the entire system. In fields such as aerospace and precision instruments, the curling device for needle roller bearings also plays an indispensable role. And the curling device for needle roller bearings, as an important technology in the bearing manufacturing process, has a decisive impact on the bearing quality. The device is a special equipment used for precisely curling the edges of the inner and outer rings of the needle roller bearing. This process not only enhances the sealing performance of the bearing, preventing the leakage of lubricating oil, but also improves the bearing's load-bearing capacity and service life. Through the precise design and optimization of each component of the curling device, its technical principle is mainly based on high-precision mechanical transmission and precise die design. By precisely controlling the curling force and angle, uniform curling of the bearing edge is achieved.

[0003] The outer ring curling device of the needle roller bearing in CN202020310760.3 includes a workbench. A support table is fixedly connected to the workbench. A turntable is rotatably connected to the support table. A plurality of placement grooves are provided on the turntable. A support frame is fixedly connected to the workbench. A moving plate is slidably connected to the support frame. Two coaxial curling wheels are rotatably connected to the moving plate. The running track of the placement groove is located below the curling wheels. When the utility model curls the bearing, the bearing is placed in the placement groove, and the turntable drives the bearing to rotate. When the bearing rotates to below the curling wheels, the moving plate moves downward to drive the curling wheels to move downward. The curling wheels abut against the outer ring of the bearing, realizing the curling of the outer ring of the bearing. Since the outer side of the curling wheel is provided with a curved surface, the force applied when the curling wheel abuts against the outer ring of the bearing is relatively uniform, so the curling quality of the bearing is higher.

[0004] However, there are certain defects in the use of the above patent. A support table is fixedly connected to the workbench. A turntable is rotatably connected to the support table.

Under the thrust of the first cylinder 10, the push rod 13 moves forward, and the push block 14 pushes the bearing 9 onto the operation panel 3. At this time, the material conveying device starts to work. First, the first movable block 103 is driven by the second piston rod 102 to move the material conveying device to a designated position. At the same time, the first telescopic rod 104 pushes the support frame 105 forward. At this time, the first support plate 106 will lock the bearing 9. At the same time, the first push plate 108 locks the processed bearing 9 on the rotating shaft 16 at this time. Then, the first movable block 103 moves longitudinally to transport the bearing 9 to be processed and the processed bearing 9 to the designated position. Subsequently, in the material conveying device, the first telescopic rod 104 retracts the support frame 105, moves the first movable block 103 to the designated position again, and the first telescopic rod 104 pushes the support frame 105 forward.

The first movable block 103 moves longitudinally again driven by the second piston rod 102. When the second support plate 107 reaches the rotating shaft 16 at the top of the turntable, the pressing device starts. Under the movement of the third cylinder 112 and the third piston rod 113, the pressing block 115 presses down tightly on the bearing 9 to ensure that it is firmly fixed on the rotating shaft 16. At this time, the second push plate 109 pushes the processed bearing 9 away from the operation panel 3, and the bearing 9 smoothly slides into the collection box 20 with the movement of the second push plate 109. When the material conveying device is working, the positioning device will follow the movement state of the material conveying device to position the bearing 9, facilitating the next processing by the hemming machine 205.

In addition, the setting of the third connecting plate 208 and the second sliding rod 209 enables the hemming machine 205 to be finely adjusted according to the size of the bearing 9 during the processing to meet the processing requirements of different specifications of bearings 9.

[0044] Specifically, a plurality of threaded holes 110 are provided through the first support plate 106, the second support plate 107, the first push plate 108, and the second push plate 109.

The first support plate 106, the second support plate 107, the first push plate 108, and the second push plate 109 are fixed to the support frame 105 by positioning screws 111. When bearings 9 of different sizes need to be processed, it is convenient to replace different accessories on the material conveying device to meet the processing requirements of bearings 9 of different specifications.

[0046] Specifically, a feeding machine 17 is provided on one side of the operating table 1, and a rotating storage hopper 18 is installed on the top of the feeding machine 17.

[0047] In this embodiment, the rotating storage hopper 18 at the top of the feeding machine 17 is used to adjust the supply of bearings 9 to ensure the continuity of the production process. During processing, workers only need to introduce the bearings 9 to be processed into the rotating storage hopper 18, and the rotating storage hopper 18 will automatically rotate to sequentially transport the scattered bearings 9 into the bending slide 23.

[0048] Specifically, a bending slide 23 is installed in the rotating storage hopper 18, and the other side of the bending slide 23 is connected to the slide 7.

[0049] In this embodiment, the bending slide 23 is used to transport the bearings 9. The bending slide 23 sequentially transports the bearings 9 to be processed into the slide 7. When the bearings 9 are transported into the slide 7, the bearings 9 will be automatically positioned under the action of the stop block 8 to ensure the correct posture of the bearings 9 before entering the flanging machine 205.

[0050] Specifically, four third support columns 19 are provided on the side of the operating table 1 away from the feeding machine 17, and a collection box 20 is installed and connected to the tops of the four third support columns 19.

[0051] In this embodiment, the collection box 20 is used to conveniently collect the processed products, reduce the downtime, and improve the production efficiency.

After continuous pushing, they will fall into the collection box 20 in sequence. The function of installing the inclined plate 22 is to make the processed bearings 9 fall into the collection box 20 from the operation plate 3 in sequence, facilitating the subsequent sorting and packaging by workers.

[0054] The principle of the present utility model is as follows: Firstly, under the action of the rotating storage hopper 18 at the top of the feeding machine 17, the scattered bearings 9 are successively conveyed into the bending slide 23. The bending slide 23 transports the bearings 9 to be processed into the slide 7 in sequence. When the bearing 9 is transported into the slide 7, the bearing 9 will be automatically positioned under the action of the stop block 8. Subsequently, under the thrust of the first cylinder 10, the push rod 13 advances forward, and the push block 14 pushes the bearing 9 onto the operation plate 3. At this time, the material conveying device starts to work. Firstly, driven by the second piston rod 102, the first movable block 103 moves the material conveying device to the designated position. At the same time, the first telescopic rod 104 pushes the support frame 105 forward. At this time, the first support plate 106 will lock the bearing 9. At the same time, the first push plate 108 locks the processed bearing 9 on the rotating shaft 16 at this position. Then, the first movable block 103 moves longitudinally to transport the bearing 9 to be processed and the processed bearing 9 to the designated position. Subsequently, in the material conveying device, the first telescopic rod 104 retracts the support frame 105, moves the first movable block 103 to the designated position again, and the first telescopic rod 104 pushes the support frame 105 forward. At this time, the second support plate 107 fixes the bearing 9 just about to be processed. At this time, the second push plate 109 is on one side of the processed bearing 9. The first movable block 103 moves longitudinally again driven by the second piston rod 102. When the second support plate 107 reaches the rotating shaft 16 at the top of the turntable, the pressing device starts. Under the movement of the third cylinder 112 and the third piston rod 113, the pressing block 115 presses down tightly on the bearing 9 to ensure its firm fixation on the rotating shaft 16. At this time, the second push plate 109 pushes the processed bearing 9 away from the end of the operation plate 3, and the bearing 9 smoothly slides into the collection box 20 with the movement of the second push plate 109. After the pressing device on the top of the second support plate 107 presses the bearing 9 into the turntable, the first telescopic rod 104 retracts. In the positioning device, the second telescopic rod 203 pushes the positioning block 204 to completely position the bearing 9. Subsequently, the curling machine 205 starts to work. The first slide bar 206 drives the third movable block 207. A second slide bar 209 is provided on one side of the third movable block 207, and a fourth movable block 210 is installed in the second slide bar 209.
