[0002] Bearings are very important components in mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during the transmission process.

[0003] Bearings operate by replacing sliding friction with rolling friction. They are highly versatile, standardized, and serialized mechanical components, typically consisting of two rings, a set of rolling elements, and a cage. Sealed bearings also incorporate lubricants and sealing rings, forming the basic structure of a bearing.

[0004] During the quality control stage of bearing processing, the processing accuracy of the bearing is tested through means such as dimensional measurement, hardness testing, ultrasonic testing, and magnetic testing. A fixing device is required during the testing process. Traditional fixing devices cannot allow the bearing to rotate for dynamic testing. While not being very flexible, it is very easy to cause the problem of low accuracy of the test data. Therefore, a bearing processing accuracy detection device is proposed. Utility Model Content

[0009] Furthermore, a fixing cylinder is provided at the bottom of the base plate, the bottom of the driving motor is fixedly installed to the inner bottom wall of the fixing cylinder, and the outer surface of the fixing cylinder is provided with threaded patterns.

[0010] Furthermore, the bottom of the rotating disk and the top of the bottom plate are rotatably connected, and the inner ring fixing frame transversely penetrates the side wall of the triangular tube and is slidably connected to the triangular tube.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 5 In this embodiment, a bearing processing accuracy detection device includes a base plate 1, an adjustment plate 2 provided at the bottom of the base plate 1, and a plurality of support legs 3 fixedly installed at the bottom of the base plate 1. An inner ring fixing assembly 4 is provided at the top of the base plate 1, and an outer ring fixing assembly 5 is provided on the outer side of the adjustment plate 2.

[0028] The inner ring fixing assembly 4 includes a driving motor 401 arranged below the base plate 1, a rotating disk 402 fixedly mounted on the top of the driving motor 401, a triangular cylinder 403 plugged and fixed to the top of the rotating disk 402, a plurality of inner ring fixing frames 404 movably connected to the sides of the triangular cylinder 403, a plurality of elliptical disks 405 rotatably connected to the inner bottom wall of the triangular cylinder 403, an adjusting pin 406 rotatably connected to the top of the triangular cylinder 403, and an adjusting gear 407 movably connected to the outer side of the adjusting pin 406;

[0029] The outer ring fixing assembly 5 includes a sliding seat 501 movably connected to the top of the base plate 1, a limiting plate 502 fixedly installed on the top of the sliding seat 501, an adjusting nut 503 threadedly connected to the side of the limiting plate 502, an outer ring fixing frame 504 rotatably connected to the side of the adjusting nut 503, and a rotating cylinder 505 rotatably connected to the bottom of the adjusting plate 2.

[0030] In this example, a fixing cylinder 408 is provided at the bottom of the base plate 1 , the bottom of the driving motor 401 is fixedly mounted to the inner bottom wall of the fixing cylinder 408 , and the outer surface of the fixing cylinder 408 is provided with threaded patterns.

[0031] In this embodiment, the bottom of the rotating disk 402 is rotatably connected to the top of the bottom plate 1 , and the inner ring fixing frame 404 transversely penetrates the side wall of the triangular tube 403 and is slidably connected to the triangular tube 403 .

[0032] In this example, a toothed disc 409 is provided in the middle of the elliptical disc 405 for use with the adjusting gear 407 , and the upper and lower inner walls of the elliptical disc 405 are slidably connected to the upper and lower side walls of the toothed disc 409 .

[0033] By setting a toothed disc 409 in the middle of the elliptical disc 405 and engaging with the adjusting gear 407, the elliptical disc 405 can rotate under the drive of the adjusting gear 407. The rotating elliptical disc 405 squeezes the inner ring fixing frame 404 during the rotation process, thereby fixing the inner ring of the bearing.

[0034] In this example, the bottom of the adjusting pin 406 vertically passes through the top wall of the triangular cylinder 403 and is rotatably connected to the triangular cylinder 403 via a thread. A cross pin 410 is provided at the bottom of the adjusting pin 406 .

[0035] A cross-shaped through-hole is formed on the top of the adjusting gear 407 , and a cross pin 410 at the bottom of the adjusting pin 406 vertically passes through the cross-shaped through-hole and is slidably connected to the adjusting gear 407 .

[0036] By setting a cross pin 410 at the bottom of the adjusting pin 406 to match the cross-shaped through-hole of the adjusting gear 407, the adjusting gear 407 can slide relative to the adjusting pin 406 in the vertical direction, and the rotation of the adjusting pin 406 can drive the adjusting gear 407 to rotate in the horizontal direction.

[0037] In this embodiment, the sliding seat 501 vertically penetrates the bottom plate 1 and is slidably connected to the bottom plate 1 , and the bottom of the sliding seat 501 and the top of the adjustment plate 2 are fixedly installed.

[0038] In this embodiment, the bottom of the fixed cylinder 408 is embedded in the interior of the rotating cylinder 505 and is rotatably connected to the rotating cylinder 505 via threads.

[0039] By setting up a sliding connection between the fixed cylinder 408 and the rotating cylinder 505, the rotating cylinder 505 can move up and down on the outside of the fixed cylinder 408, thereby driving the adjustment plate 2 to move up and down. The up and down movement of the adjustment plate 2 can push the sliding seat 501 to move up and down, thereby driving the outer ring fixing frame 504 to push the outer ring and inner ring of the bearing to cause relative displacement, thereby better detecting the processing accuracy of the bearing.

[0040] In this example, opposite sides of the inner ring fixing frame 404 and the outer ring fixing frame 504 are both provided with a locking slot for fixing and limiting.

[0041] The working principle of the above embodiment is:

[0042] By inserting the bearing into the locking slot of the outer ring fixing frame 504, rotating the adjusting nut 503 makes the adjusting nut 503 move inside the limit plate 502, and the movement of the adjusting nut 503 pushes the outer ring fixing frame 504 toward the center of the device to stably clamp the outer ring of the bearing, and rotating the adjusting pin 406 makes the adjusting pin 406 move up and down on the top wall of the triangular cylinder 403. While the adjusting gear 407 slides on the outside of the cross pin 410, it rotates with the adjusting pin 406, thereby driving the elliptical disk 405 to rotate, and the elliptical disk 405 rotates to squeeze the inner ring fixing frame 404 to fix the inner ring of the bearing.

[0043] In addition, by starting the drive motor 401, the rotation of the drive motor 401 drives the rotating disk 402 to rotate, the rotation of the rotating disk 402 drives the triangular cylinder 403 to rotate, and the rotation of the triangular cylinder 403 drives the inner ring fixing frame 404 to clamp the inner ring of the bearing for rotation. The rotation of the inner ring of the bearing causes the bearing balls to continuously rotate between the inner ring and the outer ring of the bearing. Then, the detection tool is used to detect the processing accuracy of the bearing and obtain average data, thereby improving the accuracy of the detection, and thus solving the problem of poor flexibility and relatively single function of the fixing device during the bearing processing accuracy detection process.

[0044] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
