[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a bearing diameter measuring device with high accuracy, including a base 2, which has a right-angled "U" shape. A groove 4 is provided inside the base 2, and a slider 9 is inserted into the groove 4, forming a sliding connection between the slider 9 and the groove 4. This structure, by setting the groove 4, makes the movement of the slider 9 more stable. A first hydraulic cylinder 1 and a second hydraulic cylinder 7 are fixedly connected to both sides of the base 2, respectively. A clamping plate 8 is connected to one end of the first hydraulic cylinder 1, and a groove is provided on the side of the clamping plate 8. A rotating shaft 13 is rotatably connected inside the groove. The rotating shaft 13... A torsion spring 12 is fitted on the outer wall, and a measuring scale 3 is wound around the outer wall of the torsion spring 12. The right side of the measuring scale 3 is the starting point of the graduation line. The torsion spring 12 enables the automatic retraction and extension of the measuring scale 3. The measuring scale 3 and the clamping plate 8 form a sliding connection, with the measuring scale 3 located at one end of the bearing body 5. In this structure, the measuring scale 3 retracts and extends in coordination with the movement of the clamping plate 8. When the clamping plate 8 holds the bearing body 5, the measuring scale 3 retracts; when the clamping plate 8 opens, the measuring scale 3 unfolds. The graduation line of the measuring scale 3 after the clamping plate 8 holds the bearing body 5 is the diameter of the bearing body 5. A bearing body 5 is clamped between the inner side of the support block 8 and the base 2. A slider 9 is provided on the inner side of the base 2, and a drive motor 10 is installed inside the slider 9. One end of the shaft of the drive motor 10 is connected to the bottom of the support block 6. This structure can drive the support block 6 to rotate automatically through the drive motor 10, which facilitates the adjustment of the detection angle of the bearing body 5 on the support block 6. The accuracy of the detection measurement can be improved by multiple measurements. The top and bottom of the support block 6 are both mesh structures, and a negative pressure fan 11 is installed inside the support block 6. When the negative pressure fan 11 is turned on, this structure can generate negative pressure on the top of the support block 6 to prevent the bearing body 5 from being placed on the support block. The bearing body 5 on the top of block 6 is adsorbed, thus ensuring the stability of the bearing body 5 during the rotation of block 6; one end of slider 9 is connected to the second hydraulic cylinder 7, and block 6 is rotatably connected to the top of slider 9. The top of block 6 is in close contact with the bearing body 5. A measuring ruler 3 is provided on the end side of clamp 8, and one end of the measuring ruler 3 is fixedly connected to the inner side of base 2; the second hydraulic cylinder 7 can push block 6 and slider 9 to move laterally, so that the outer wall of bearing body 5 on block 6 is away from base 2, which facilitates the adjustment of the detection angle of bearing body 5 and avoids friction between the outer wall of bearing body 5 and base 2 during the rotation of bearing body 5.

[0023] Working principle: When using this highly accurate bearing diameter measuring device, first place the bearing body 5 to be measured on the top of the support block 6, so that one side of the bearing body 5 is in contact with the inner wall of the base 2. The negative pressure fan 11 is turned on, and the bearing body 5 is attracted and fixed on the top of the support block 6. Then, the first hydraulic cylinder 1 pushes the clamping plate 8 to clamp the bearing body 5. At the same time as the clamping plate 8 moves, the measuring ruler 3 on the inner side of the clamping plate 8 is also unfolded. At this time, the length of the measuring ruler 3 is the diameter of the bearing body 5. After completing the measurement of one angle, the clamping plate 8 is released. Then, the second hydraulic cylinder 7 is started. The second hydraulic cylinder 7 drives the slider 9 and the support block 6 to slide, so that the bearing body 5 on the support block 6 is away from the base 2. Then, the drive motor 10 drives the support block 6 and the bearing body 5 to rotate. After the bearing body 5 is in a suitable angle, the slider 9 and the support block 6 slide back to their original position. Then, the clamping plate 8 clamps the bearing body 5 again to measure the bearing body 5. This process is repeated until the measurement number is reached and the measurement data is recorded.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
