[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] During the implementation of this embodiment, the outer ring of the bearing is placed on the rotating vibration component 5. At this time, by operating the control box 2, the rotating vibration component 5 drives the outer ring of the bearing to move backward and rotates 180 degrees during the movement. The outer ring of the bearing is then clamped and fixed. Before the bearing is ground, the cleaning component 6 cooperates with the rotating vibration component 5 to clean the outer surface of the bearing to be ground. Finally, the rotating vibration component 5 preheats the outer ring of the bearing, and then ultrasonic vibration is performed while driving the outer ring of the bearing to rotate, and the grinding component 4 cooperates to grind its outer surface.

[0035] The grinding assembly 4 mentioned above is composed of a motor and a grinding wheel, which is a mature grinding technology means and equipment in the prior art. In this scheme, its function of grinding the outer surface of the bearing is utilized, and its internal structure, connection method and principle are not further explained.

[0036] The control box 2 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its internal structure, connection method and principle are not further explained.

[0037] Specifically, in order to achieve the rotational vibration of the bearing outer ring, refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the rotary vibration component 5 includes a dual-axis motor 51 fixedly connected to the rear end of the shell 1, a feeding mechanism 52 is commonly provided at the front and rear parts of the inner surface of the shell 1, a rotary vibration mechanism 53 is provided at the rear part of the inner surface of the shell 1 above the feeding mechanism 52, a hydraulic mechanism 54 is commonly provided at the lower side of the front and rear parts of the inner surface of the shell 1, and a blower mechanism 55 is provided at the left end of the shell 1.

[0038] For further information, see Figure 4 and Figure 5 In this embodiment, the feeding mechanism 52 includes a rectangular frame 521 fixedly connected to the inner surface of the shell 1, the inner surface of the rectangular frame 521 is rotatably connected to a threaded rod 522 fixedly connected to the front end output end of the dual-axis motor 51 through a coupling, the outer surface of the threaded rod 522 is threadedly connected to a slider rod 523 slidably connected to the inner surface of the rectangular frame 521, the outer surface of the slider rod 523 is rotatably connected to a slide plate 524, the inner surface of the slide plate 524 is annularly and equidistantly distributed and fixedly connected to four spring telescopic rods 525, the ends of the four spring telescopic rods 525 away from each other are fixedly connected to an arc block 526, the front left end of the rectangular frame 521 is fixedly connected to a rack 527, and the lower part of the outer surface of the slide plate 524 is fixedly connected to a gear 528 meshing with the rack 527.

[0039] During the implementation process, the outer ring of the bearing is placed in the middle of the four arc blocks 526. Under the action of the spring telescopic rod 525, the outer ring of the bearing is fixed. Then, the front output end of the dual-axis motor 51 is started to drive the threaded rod 522 to rotate through the coupling. Since the slider rod 523 and the threaded rod 522 are threadedly connected, the threaded rod 522 will drive the slider rod 523 to slide backward on the inner surface of the rectangular frame 521 during the rotation. When the gear 528 is meshed with the rack 527, the gear 528 will drive the slide plate 524 to rotate 180 degrees, so that the outer ring of the bearing can rotate 180 degrees, and then continue to drive the outer ring of the bearing to continue to move backward, thereby realizing automatic loading and reducing manual intervention. The continuous and smooth movement of the outer ring of the bearing avoids grinding defects caused by position offset or uneven heating, thereby improving the grinding effect and the service life of the bearing.

[0040] The gear 528 and the rack 527 mentioned above can rotate 180 degrees after being engaged, and in this solution, there is a certain resistance to the rotation between the slider rod 523 and the slide plate 524, so that when the gear 528 and the rack 527 are engaged, the slide plate 524 can rotate.

[0041] For further information, see Figure 4 and Figure 6 In this embodiment, the rotary vibration mechanism 53 includes a rotating rod 531 fixedly connected to the rear end output end of the dual-axis motor 51 through a coupling, a circular plate rod 532 is rotatably connected to the inner surface of the shell 1, a fixed plate 533 is fixedly connected to the inner surface of the circular plate rod 532, an ultrasonic transducer 534 is fixedly installed at the rear end of the fixed plate 533, four waveguide rods 535 are fixedly connected to the front end of the fixed plate 533 in an annular manner with equal distances, a disc 536 is commonly fixedly connected to the front ends of the four waveguide rods 535, and a pulley group 537 is commonly fixedly connected to the outer surface of the rotating rod 531 and the outer surface of the circular plate rod 532.

[0042] For further information, see Figure 4 , Figure 7 and Figure 8 In this embodiment, the hydraulic mechanism 54 includes an oil tank 541 fixedly connected to the rear part of the inner surface of the shell 1, an electric cylinder 542 is fixedly installed on the front part of the inner surface of the shell 1, and a push plate 543 slidably connected to the inner surface of the oil tank 541 is fixedly connected to the rear end of the electric cylinder 542. A connecting pipe 1 544 rotatably connected to the inner surface of the circular plate rod 532 is fixedly connected to the rear end of the inner surface of the oil tank 541, and the inner surface of the circular plate rod 532 passes through and extends to the inner surface of the disc 536, and a connecting pipe 2 545 is fixedly connected thereto. Four piston rods 546 are slidably connected to the inner surface of the disc 536 in an annular manner and equidistantly distributed, and a clamping block 547 is fixedly connected to the front end of the four piston rods 546.

[0043] During the implementation process, after the outer ring of the bearing on the slide plate 524 moves to the set position, the inner surface of the outer ring of the bearing will be sleeved on the four clamping blocks 547. At this time, the electric cylinder 542 is started to push the push plate 543 to slide on the inner surface of the oil tank 541, thereby pushing the pressurized oil in the oil tank 541 into the inner cavity of the circular plate rod 532 through the connecting pipe 1 544, and enters the inner cavity of the disc 536 through the connecting pipe 2 545 to push the four piston rods 546 to slide away from each other on the inner surface of the disc 536, thereby driving the four clamping blocks 547 to support and fix the inner surface of the outer ring of the bearing, ensuring that the outer ring of the bearing remains stable during the grinding process and will not deform or loosen, thereby improving the grinding accuracy and surface quality, reducing the grinding error caused by unstable fixation, and ensuring uniform grinding and longer service life of the outer ring of the bearing.

[0044] Secondly, when grinding the outer ring of the bearing, the rear end output end of the dual-axis motor 51 is started to drive the rotating rod 531 to rotate through the coupling, and under the transmission action of the pulley group 537, the slider rod 523 is driven to rotate, so that the disc 536 rotates to cooperate with the grinding component 4 to grind the outer surface of the outer ring of the bearing. At the same time, the ultrasonic transducer 534 is started, and the outer ring of the bearing is driven to vibrate ultrasonically under the transmission action of the waveguide rod 535. The transmission of ultrasonic vibration through the waveguide rod 535 can effectively reduce the heat accumulation caused by friction during the grinding process, avoid the influence of overheating on the outer ring of the bearing, and at the same time improve the material removal efficiency during the grinding process, reduce the roughness of the processed surface, and ultimately improve the grinding quality and the performance stability of the outer ring of the bearing.

[0045] The dual-axis motor 51 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, the couplings on both sides thereof can rotate independently and can stop after rotating to a set number of circles. Its internal structure, connection method and principle will not be elaborated any more.

[0046] The ultrasonic transducer 534 and waveguide rod 535 mentioned above are both mature ultrasonic vibration technical means and equipment in the prior art. This solution utilizes their ability to generate and transmit ultrasonic waves, and their internal structure, connection method and principle are no longer elaborated.

[0047] The pulley assembly 537 mentioned above is composed of two pulleys and a belt in the prior art.

[0048] For further information, see Figure 4 and Fig. 9In this embodiment, the blowing mechanism 55 includes an air pump 551 fixedly connected to the lower rear side of the inner surface of the shell 1, and a hot air box 552 is fixedly installed at the left end of the shell 1. The air pump 551 is connected to the hot air box 552 through a pipeline, and the upper end of the hot air box 552 penetrates and extends to the inner surface of the shell 1 and is fixedly connected with a blowing pipe 553.

[0049] From the above, it can be seen that before grinding the outer ring of the bearing, the air pump 551 can be started, and air can be sucked in through the circular hole at the rear end of the shell 1 and then enter the hot air box 552 through the pipe. The air temperature is heated by the hot air box 552 and then blown out through the blow pipe 553. The bearing is preheated in conjunction with the rotation of the bearing, which can effectively increase the temperature of the outer ring of the bearing, reduce the internal stress of the metal material, make its surface more uniform and stable, and help reduce the risk of deformation or cracks caused by temperature changes during the grinding process, ensuring that the material of the outer ring of the bearing has better processing performance during grinding, thereby improving the grinding accuracy and surface quality.

[0050] The hot air box 552 mentioned above is a mature technical means and equipment for heating air in the prior art. In this solution, its function of heating air is utilized, and its internal structure, principle and connection method are not further explained.

[0051] Embodiment 2: Based on Embodiment 1, this embodiment adds a cleaning component 6 for cleaning the outer surface of the bearing outer ring before grinding, so as to achieve the purpose of cleaning the outer surface of the bearing outer ring before grinding.

[0052] Specifically, in order to clean the outer surface of the bearing outer ring before grinding, refer to Figure 4 , Fig.10 and Fig.11 In this embodiment, the cleaning component 6 includes a water tank 61 fixedly connected to the lower part of the inner surface of the shell 1, a cleaning mechanism 62 is provided at the rear of the inner surface of the shell 1, a cleaning mechanism 63 is provided at the lower end of the cleaning mechanism 62, and a collecting mechanism 64 is provided on the inner surface of the shell 1.

[0053] For further information, see Figure 4 and Fig.10 In this embodiment, the cleaning mechanism 62 includes a fixing frame 621 fixedly connected to the rear portion of the inner surface of the outer shell 1, a U-shaped tube 623 is fixedly connected to the upper portion of the inner surface of the water tank 61 and extends to the rear end of the outer shell 1, the right portion of the upper end of the U-shaped tube 623 penetrates and extends to one end of the fixing frame 621 and is fixedly connected to a connecting tube 1 624, the left portion of the upper end of the U-shaped tube 623 penetrates and extends to the rear portion of the inner surface of the outer shell 1 and is fixedly connected to a connecting tube 2 625 fixedly connected to the inner surface of the blowing pipe 553, and the lower end of the U-shaped tube 623 is located in the inner cavity of the water tank 61 and is fixedly connected to a water pump 622.

[0054] For further information, see Figure 4 and Fig.11 In this embodiment, the cleaning mechanism 63 includes two spring telescopic rods 631 fixedly connected to the lower end of the fixing frame 621, and the lower ends of the two spring telescopic rods 631 are commonly fixedly connected with a curved scraper 632.

[0055] During the implementation process, before the outer ring of the bearing is ground, the rotating vibration mechanism 53 can be used. When the outer ring of the bearing is rotating, the water pump 622 is started so that the water pump 622 draws the coolant in the water tank 61 into the U-shaped tube 623. Under the action of the U-shaped tube 623, the coolant can evenly flow into the connecting tube 1 624 and the connecting tube 2 625. The coolant in the connecting tube 1 624 can clean the debris on the outer ring of the bearing, and can also flush the grinding debris during the grinding process. The outer surface of the flushed outer ring of the bearing can be scraped under the action of the spring telescopic rod 2 631 and the arc scraper 632 to further remove fine impurities. The debris on the surface of the outer ring of the bearing can be effectively cleaned during the grinding process, and the debris generated by the grinding can be flushed to ensure the smoothness of the surface of the outer ring of the bearing. Keeping it clean can reduce the resistance and heat accumulation during the grinding process, improve the grinding accuracy, reduce wear, and ultimately improve the processing quality and service life of the outer ring of the bearing.

[0056] Secondly, the coolant in the connecting pipe 625 can be combined with the wind in the blowing pipe 553. At this time, the hot air box 552 is not started, and the outer ring of the bearing is cooled during the grinding process. The mixed spray can provide an effective cooling effect for the outer ring of the bearing. The combination of coolant and airflow helps to quickly take away the heat generated during the grinding process, preventing the outer ring of the bearing from being deformed or damaged due to overheating. It can maintain a stable processing temperature and avoid surface quality problems caused by temperature fluctuations. At the same time, it promotes the removal of grinding debris and keeps the processing area clean, thereby improving the grinding accuracy, reducing wear, and effectively improving the surface quality of the outer ring of the bearing.

[0057] For further information, see Figure 4 and Fig.10 In this embodiment, the collecting mechanism 64 includes two circular hole plates 641 which are fixedly connected to the inner surface of the outer shell 1 symmetrically on the left and right sides. The ends of the two circular hole plates 641 close to each other are fixedly connected to the rectangular frame 521. A collecting frame 642 is fixedly connected to the inner surface of the outer shell 1 below the two circular hole plates 641. The inner surface of the collecting frame 642 penetrates and extends to the upper inner surface of the water tank 61 and is fixedly connected to a return pipe 643.

[0058] During the implementation process, the coolant and debris in the bearing grinding process will fall on the two circular hole plates 641 under the action of gravity, and the debris will be retained at the upper end of the circular hole plates 641 under the action of the two circular hole plates 641, and the coolant will return to the water tank 61 through the collection frame 642 and the return pipe 643, ensuring the recycling of the coolant and reducing resource waste. It not only maintains the cleanliness and stability of the coolant, but also ensures the continuous cooling effect of the grinding area, which helps to improve the machining accuracy of the bearing outer ring, reduce thermal deformation, and improve the grinding effect and the service life of the bearing.

[0059] Working process: When in use, the outer ring of the bearing is loaded by the loading mechanism 52, and the outer ring of the bearing is supported internally by the cooperation of the rotating vibration mechanism 53 and the hydraulic mechanism 54, and the outer ring of the bearing can be driven to rotate and vibrate. Before the outer ring of the bearing is ground, the outer surface of the outer ring of the bearing can be cleaned by the cleaning mechanism 62 and the cleaning mechanism 63, and the outer ring of the bearing can be preheated by the hair dryer mechanism 55. During the grinding process, the cleaning mechanism 62 and the cleaning mechanism 63 can still clean the outer ring of the bearing, and the hair dryer mechanism 55 and the cleaning mechanism 62 cooperate with each other to perform mixed spraying on the outer ring of the bearing for cooling.
