[0002] In the bearing manufacturing process, the press-fitting of the seal ring is a crucial step. The seal ring effectively prevents impurities such as dust and moisture from entering the bearing, thereby ensuring the normal operation and service life of the bearing.
[0003] When using the above-mentioned technology, the following technical problems were found in the existing technology: Currently, existing bearing seal ring pressing mechanisms typically require the bearing to be transported to the pressing position, and then the sealing ring is pressed onto the bearing by a pressing device. However, traditional bearing transport methods often suffer from low transport accuracy, which can easily lead to positional deviation of the bearing during pressing, thus affecting the pressing quality of the sealing ring. In addition, existing pressing mechanisms are not convenient to operate and have low efficiency during the removal and pressing of the sealing ring. Therefore, we designed a bearing seal ring pressing mechanism to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A bearing seal ring pressing mechanism includes an operating table. A conveyor belt is rotatably connected to the inner side of the operating table. A bracket is fixed to one side of the top of the operating table. A pressure plate is assembled at the bottom of the inner side of the bracket. A pressure cylinder is fixed to one end of the bottom of the pressure plate. A pick-and-place cylinder is slidably connected to the inner side of the pressure cylinder. A spring is fixed to the inner side of the pressure cylinder. The bottom end of the spring is fixed to the pick-and-place cylinder. A second spacer rod and a first spacer rod are rotatably connected to the other side of the top of the operating table. A spacer mechanism is provided on the other side of the operating table for limiting the position of a pair of bearings driven by the gear and the spacer rod.
[0006] As a preferred embodiment of the bearing seal ring press-fitting mechanism provided by this utility model, the distance fixing mechanism includes a U-shaped plate, a main gear, a driven gear, a rotating rod, and a hydraulic rod. The other side of the bottom end of the operating table is fixed with a U-shaped plate. The two ends of the inner top of the U-shaped plate are rotatably connected to the main gear and the driven gear. The top ends of the main gear and the driven gear are respectively fixed to the distance fixing rod two and the distance fixing rod one. The main gear and the driven gear are meshed together.
[0007] In a preferred embodiment of the bearing seal ring press-fitting mechanism provided by this utility model, the bottom end of the main gear is fixed with a rotating rod passing through a U-shaped plate, and one end of the bottom end of the U-shaped plate is rotatably connected to a hydraulic rod, the output end of the hydraulic rod being rotatably connected to one end of the rotating rod.
[0008] In a preferred embodiment of the bearing seal ring press-fitting mechanism provided by this utility model, the bottom end of the U-shaped plate is fixed with limit rod A and limit rod B, and one end of the rotating rod is in contact with limit rod A and limit rod B respectively.
[0009] In a preferred embodiment of the bearing seal ring pressing mechanism provided by this utility model, a storage cylinder is fixed on one side of the top of the operating table, and a large number of seal rings are provided on the inner side of the storage cylinder.
[0010] In a preferred embodiment of the bearing seal ring pressing mechanism provided by this utility model, an I-shaped slide is slidably connected to the inner side of the bracket, a pressure plate is rotatably connected to the bottom end of the I-shaped slide, an electric push rod is mounted on the top end of the inner side of the I-shaped slide, the output end of the electric push rod is fixed to the bracket, and a servo motor is mounted on the bottom end of the inner side of the I-shaped slide, the output end of the servo motor passes through the I-shaped slide and is fixed to the pressure plate.
[0011] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.
[0012] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:
[0013] This utility model provides a bearing seal ring pressing mechanism. Bearings are conveyed via a conveyor belt, while one side of a spacer rod resists the conveying of the bearings. A hydraulic rod is activated, driving a rotating rod to rotate, which in turn drives a main gear and a second spacer rod to rotate. The main gear drives a driven gear and a first spacer rod to rotate synchronously. The rotation directions of the second and first spacer rods are opposite. When the first spacer rod effectively resists the bearings, several bearings are conveyed on the conveyor belt. When the first spacer rod releases the resisted bearings, it effectively resists the next bearing to be pressed. This cycle repeats, effectively conveying several bearings at a fixed distance, thereby improving the accuracy of bearing pressing.
[0014] The servo motor is started to rotate the pressure plate, pressure cylinder, and pick-and-place cylinder onto the storage cylinder. Then, the electric push rod is started to drive the I-shaped slide, pressure plate, pressure cylinder, and pick-and-place cylinder to press and remove the sealing ring inside the storage cylinder. At this time, the sealing ring is sleeved on the outside of the pick-and-place cylinder. Then, the electric push rod drives the pressure plate, pressure cylinder, and pick-and-place cylinder to move downwards, and the rotating pressure plate drives the pressure cylinder and pick-and-place cylinder to press the bearing. The pick-and-place cylinder and the bearing resist each other and contract, while the bottom end of the pressure cylinder squeezes the sealing ring onto the bearing, thereby effectively pressing the sealing ring onto the bearing.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0025] Example 1
[0026] Please refer to Figures 1-4A bearing seal ring pressing mechanism includes an operating table 1, a conveyor belt 3 rotatably connected to the inner side of the operating table 1, a bracket 2 fixed to one side of the top of the operating table 1, a pressure plate 8 assembled at the bottom of the inner side of the bracket 2, a pressure cylinder 9 fixed to one end of the bottom of the pressure plate 8, a pick-and-place cylinder 10 slidably connected to the inner side of the pressure cylinder 9, a spring 20 fixed to the inner side of the pressure cylinder 9, and the bottom end of the spring 20 fixed to the pick-and-place cylinder 10. A second spacer 15 and a first spacer 14 are rotatably connected to the other side of the top of the operating table 1, and a spacer mechanism for driving the driven gear 13 and the first spacer 14 to limit the bearing position is provided on the other side of the operating table 1.
[0027] In use, the conveyor belt 3 is started to drive the bearing to the designated position. At this time, the distance mechanism effectively drives several bearings to be transported at a distance. After the bearings are transported to the designated pressing position, the pressure plate 8 is rotated to drive the pressure cylinder 9 and the pick-and-place cylinder 10 to apply pressure to the sealing ring in the storage cylinder 6. At this time, the sealing ring is sleeved on the outside of the pick-and-place cylinder 10. Then, the pick-and-place cylinder 10 is rotated to drive the pressure cylinder 9, the pick-and-place cylinder 10 and the sealing ring to press the bearing. Therefore, the pressure plate 8 drives the pressure cylinder 9 and the pick-and-place cylinder 10 to apply pressure to the bearing, and the pick-and-place cylinder 10 retracts under the resistance of the bearing. The pressure cylinder 9 effectively squeezes the sealing ring on the outside of the pick-and-place cylinder 10 onto the bearing, which facilitates the pressing of the sealing ring onto the bearing, thereby greatly improving the practicality and convenience of bearing pressing.
[0028] The distance-fixing mechanism includes a U-shaped plate 11, a main gear 12, a driven gear 13, a rotating rod 16, and a hydraulic rod 17. A U-shaped plate 11 is fixed to the other side of the bottom of the operating platform 1. The main gear 12 and the driven gear 13 are rotatably connected to both ends of the inner top of the U-shaped plate 11. The top ends of the main gear 12 and the driven gear 13 are respectively fixed to distance-fixing rod 15 and distance-fixing rod 14. The main gear 12 and the driven gear 13 are meshed together.
[0029] The bottom end of the main gear 12 passes through the U-shaped plate 11 and is fixed with a rotating rod 16. One end of the bottom end of the U-shaped plate 11 is rotatably connected to a hydraulic rod 17, and the output end of the hydraulic rod 17 is rotatably connected to one end of the rotating rod 16.
[0030] Limiting rods A18 and B19 are fixed at the bottom of the U-shaped plate 11, and one end of the rotating rod 16 is in contact with the limiting rods A18 and B19 respectively.
[0031] Limiting rods A18 and B19 effectively limit the rotation angle of rotating rod 16, allowing rotating rod 16 to drive distance rod 2 15 and distance rod 1 14 to accurately resist the bearing, thereby ensuring the accuracy of distance conveying.
[0032] Specifically, the bearings are conveyed via conveyor belt 3, while one side of the spacer rod 14 resists the conveying of the bearings. The hydraulic rod 17 is activated to drive the rotating rod 16 to rotate, which in turn drives the main gear 12 and the spacer rod 15 to rotate. At this time, the main gear 12 drives the driven gear 13 and the spacer rod 14 to rotate synchronously. The rotation directions of the spacer rod 15 and the spacer rod 14 are opposite. When the spacer rod 14 effectively resists the bearings, several bearings are conveyed on the conveyor belt 3. When the spacer rod 14 releases the resisted bearings, it effectively resists the next bearing to be pressed. This cycle is repeated to effectively convey several bearings at a fixed distance, thereby improving the accuracy of bearing pressing.
[0033] A storage cylinder 6 is fixed to one side of the top of the operating table 1. A large number of sealing rings are provided on the inner side of the storage cylinder 6. An I-shaped slide 4 is slidably connected to the inner side of the support 2. A pressure plate 8 is rotatably connected to the bottom end of the I-shaped slide 4. An electric push rod 5 is assembled at the top of the inner side of the I-shaped slide 4. The output end of the electric push rod 5 is fixed to the support 2. A servo motor 7 is assembled at the bottom of the inner side of the I-shaped slide 4. The output end of the servo motor 7 passes through the I-shaped slide 4 and is fixed to the pressure plate 8.
[0034] Furthermore, by starting the servo motor 7, the pressure plate 8, pressure cylinder 9, and pick-up / placement cylinder 10 are rotated onto the storage cylinder 6. Then, the electric push rod 5 is started to drive the I-shaped slide 4, pressure plate 8, pressure cylinder 9, and pick-up / placement cylinder 10 to press and remove the sealing ring inside the storage cylinder 6. At this time, the sealing ring is sleeved on the outside of the pick-up / placement cylinder 10. Then, the electric push rod 5 drives the pressure plate 8, pressure cylinder 9, and pick-up / placement cylinder 10 to move downwards, and the rotating pressure plate 8 drives the pressure cylinder 9 and pick-up / placement cylinder 10 to press the bearing. The pick-up / placement cylinder 10 resists the bearing and contracts, while the bottom end of the pressure cylinder 9 squeezes the sealing ring onto the bearing, thereby effectively pressing the sealing ring onto the bearing.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
