In modern industrial production, the demand for bearings is enormous, and there are extremely high requirements for production efficiency and quality control.

[0003] Traditional manual inspection methods for bearing outer ring dimensions are not only inefficient and unable to meet the demands of mass production, but also highly susceptible to human error, leading to large errors and frequent missed or false positives. While some existing automated inspection equipment has improved efficiency to some extent, it suffers from complex structures, high costs, and poor adaptability, making it unable to accurately and efficiently perform batch inspections of bearing outer rings of different specifications. Furthermore, the lack of effective positioning measures during the transport of bearing outer rings causes positional deviations, affecting inspection accuracy and efficiency. Therefore, improvements are needed. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a batch inspection device for bearing outer ring dimensions, including a base frame 1 and a conveyor frame 2. A driven roller 3 is rotatably connected to the inner side of the conveyor frame 2. A motor 4 is fixedly installed on one side of the conveyor frame 2. A drive roller 5 is fixedly installed at the output end of the motor 4. A conveyor belt 6 is sleeved around the drive roller 5 and the driven roller 3. A gantry frame 7 is fixedly installed on the top of the conveyor frame 2. A telescopic cylinder 8 is fixedly installed on the top of the gantry frame 7. A frame 9 is fixedly installed at the output end of the telescopic cylinder 8. A motor 10 is fixedly installed on the inner surface of the frame 9. A disc 11 is fixedly installed at the output end of the motor 10. A groove 12 is opened at the bottom of the disc 11. A motor 13 is fixedly installed on the outer wall of the disc 11. A bidirectional lead screw 14 is fixedly installed at the output end of the motor 13. The outer wall of 14 is symmetrically threaded with a slider 15. An inner support block 16 is fixedly installed at the bottom of the slider 15. An electric telescopic rod 17 is fixedly installed on one side of the gantry 7. A U-shaped frame 18 is fixedly installed at the output end of the electric telescopic rod 17. A sliding hole 19 is opened through the side of the U-shaped frame 18 away from the electric telescopic rod 17. A detection rod 20 is slidably connected inside the sliding hole 19. A round block 21 is fixedly installed at the end of the detection rod 20 near the U-shaped frame 18. A spring 22 is fixedly installed at the side of the round block 21 away from the detection rod 20. The driving roller 5 and the driven roller 3 are rotatably connected to the conveyor belt 6. The bottom frame 1 is located at the bottom of the conveyor frame 2. The bottom frame 1 is fixedly connected to the conveyor frame 2. The slider 15 is slidably connected to the chute 12. The end of the spring 22 away from the round block 21 is fixedly connected to the U-shaped frame 18.

[0023] In this embodiment, the bearing outer ring is conveyed by the conveyor belt 6 driven by motor 4, realizing automated feeding. Compared with manual operation, the detection efficiency is greatly improved. The telescopic cylinder 8 and motor 13 work together to first bring the disc 11 close to the bearing outer ring, and then fix it by the inner support block 16. The operation process is compact and the fixing effect is good, avoiding errors caused by the displacement of the bearing outer ring during detection. By precisely controlling the telescopic cylinder 8, the bearing outer ring is moved to be horizontally aligned with the detection rod 20. Combined with the electric telescopic rod 17 pushing the detection rod 20 to fit against the bearing outer ring, and the motor 10 driving the bearing outer ring to rotate for detection, the compression of the spring 22 is used to determine whether the size is qualified. The detection accuracy is high and effectively solves the problems of large error, missed detection and false detection in traditional detection.

[0024] Example 2: As Figure 1 and Figure 5As shown, a rectangular frame 23 is fixedly installed at the bottom of the conveyor frame 2. A motor 24 is fixedly installed at one end of the rectangular frame 23. A two-way lead screw 25 is fixedly installed at the output end of the motor 24. A slide plate 26 is symmetrically threaded to the outer wall of the two-way lead screw 25. A connecting rod 27 is fixedly installed on the inner side of the slide plate 26. A limit rod 28 is fixedly installed at the end of the connecting rod 27 away from the slide plate 26. The slide plate 26 is slidably connected to the rectangular frame 23, the connecting rod 27 is slidably connected to the conveyor frame 2, and the limit rod 28 is slidably connected to the conveyor belt 6.

[0025] In this embodiment, by starting the motor 24, it drives the bidirectional lead screw 25 to rotate. The bidirectional lead screw 25 drives the slide plate 26 to slide within the rectangular frame 23. The slide plate 26 drives the limiting rod 28 to move through the connecting rod 27. The two limiting rods 28 can adjust the spacing according to the specifications of the bearing outer ring to limit the bearing outer ring and prevent it from deviating on the conveyor belt 6. This ensures that the bearing outer ring can accurately reach the detection position and guarantees the accuracy and stability of the detection.

[0026] The working principle of this embodiment is as follows: When the bearing outer ring size batch inspection device is running, motor 4 first drives the active roller 5 to rotate. The active roller 5, through the cooperation of the conveyor belt 6 and the driven roller 3, drives the conveyor belt 6 to rotate, thereby conveying the bearing outer ring to the designated inspection area. When the bearing outer ring is in place, the telescopic cylinder 8 is activated, pushing the frame 9 downward, so that the disc 11 at the bottom of the frame 9 approaches the bearing outer ring. At this time, motor 3 is activated, causing it to drive the bidirectional lead screw 14 to rotate. Since the bidirectional lead screw 14 is threadedly connected to the slider 15, and the slider 15 is slidably engaged with the slide groove 12, when the bidirectional lead screw 14 rotates, the two sliders 15 will slide symmetrically along the slide groove 12, causing the inner support block 16 at the bottom to open to both sides, stably supporting and fixing the bearing outer ring, ensuring that the bearing outer ring will not be displaced during the inspection process. After the bearing outer ring is fixed, the telescopic cylinder 8 is activated, driving the frame 9 to move upward. The frame 9 then moves the fixed bearing outer ring upward together. By precisely controlling the telescopic amount of the telescopic cylinder 8, the bearing outer ring is moved to a position horizontally aligned with the detection rod 20. At this time, the electric telescopic rod 17 is activated, pushing the U-shaped frame 18 and the detection rod 20 closer to the bearing outer ring until the detection rod 20 is tightly fitted with the bearing outer ring. After the detection rod 20 and the bearing outer ring are stably fitted, the motor 10 starts to run, and its output end drives the disc 11 to rotate. The disc 11 drives the fixed bearing outer ring to rotate. During the rotation of the bearing outer ring, the detection rod 20 is displaced due to the influence of the surface shape of the bearing outer ring, causing the circular block 21 to compress the spring 22. The compression of the spring 22 reflects the dimensional changes of the bearing outer ring at different positions in real time. When the spring 22 is not compressed, it means that the bearing outer ring size is qualified. When the spring 22 is compressed, it means that the bearing outer ring size is unqualified. To ensure the bearing outer ring is in the correct position during transport, motor 4 24 can be started to drive the double-acting lead screw 25 to rotate. The double-acting lead screw 25 drives the slide plate 26 to slide within the rectangular frame 23. The slide plate 26 drives the limiting rod 28 to move through the connecting rod 27. The spacing between the two limiting rods 28 can be adjusted according to the specifications of the bearing outer ring to limit the bearing outer ring and prevent it from deviating on the conveyor belt 6. This ensures that the bearing outer ring can accurately reach the detection position and guarantees the accuracy and stability of the detection.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
