[0002] In the field of modern mechanical manufacturing, bearings are one of the core components, and their performance directly affects the operating efficiency and life of mechanical equipment. It is crucial to ensure the precise fit of the inner and outer rings of the bearings, because any slight deviation may lead to increased operating noise, increased vibration, and even early failure of the entire system. Traditional bearing inspection methods mainly rely on manual visual inspection and simple measuring tools, which are not only inefficient, but also difficult to achieve high-precision requirements.

[0003] The Chinese utility model patent publication number CN216348490U discloses an automatic detection device for bearing rings, which can effectively reduce the operation steps of manual detection, improve the detection efficiency of the detection device, and reduce the labor intensity of operators.

[0004] However, when the bearing is in use, the fit of the inner and outer rings is extremely important. The fit of the inner and outer rings is an important test data to ensure the smooth operation and service life of the equipment and improve the overall performance. However, the above patent cannot detect the fit of the inner and outer rings of the bearing. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a device for automatically detecting the fit between the inner and outer rings of a bearing, which can automatically and accurately detect the fit between the inner and outer rings of a bearing.

[0008] A first driving assembly is installed inside the rotating disk, and the first driving assembly is used to drive two first clamping blocks to clamp the inner ring of the bearing;

[0009] A second driving assembly is installed inside the moving block, and the second driving assembly is used to drive the second clamping block to clamp the outer ring of the bearing.

[0010] Furthermore, the first driving assembly includes a movable groove opened inside the turntable, a first screw rod movably installed inside the movable groove, a driving block movably installed on the outer wall of the first screw rod, a first sliding block fixedly connected to the bottom of the first clamping block, a driving rod movably installed on both sides of the driving block, and a first sliding groove opened on the top of the turntable, and one end of the driving rod away from the driving block is movably installed on the outer wall of the first sliding block, and the first sliding block and the first sliding groove correspond to each other.

[0011] Furthermore, a driving motor is fixedly mounted on the top of the base plate, and the bottom of the turntable is fixedly mounted on the output end of the driving motor.

[0012] Furthermore, the second driving assembly includes a second screw rod movably mounted inside the moving block and a fixed ear plate fixedly connected to the outer wall of the second clamping block, and the second screw rod is slidably mounted on the fixed ear plate.

[0013] Furthermore, a first cross groove is formed on the outer wall of the first screw rod, and a second cross groove is formed on the top of the second screw rod.

[0014] Furthermore, a second sliding block is fixedly connected to the bottom of the moving block, a second sliding groove is provided inside the supporting block, and the second sliding block corresponds to the second sliding groove.

The inner and outer rings of the bearing can be clamped and fixed separately to prevent errors during detection.

[0018] Secondly, during the inspection, the turntable is driven by the driving motor to rotate on the top of the support plate. If there is a problem with the fit between the inner and outer rings of the bearing, the position of the outer ring will move and be detected by the infrared rangefinder, so that the accuracy of the fit between the inner and outer rings can be achieved.

[0019] Furthermore, when the turntable rotates on the top of the support plate, the roller can support the turntable on the top of the support plate, and at the same time reduce the friction between the support plate and the turntable when the turntable rotates, thereby preventing errors during detection.

[0045] The working principle of the utility model is:

[0046] When in use, place the bearing on the top of the turntable 3, and place the first clamping block 4 on the inner ring of the bearing. Then insert a cross screwdriver into the first cross slot 504, and drive the first screw rod 501 to rotate by turning the cross screwdriver. When the first screw rod 501 rotates, the two first sliding blocks 401 are simultaneously expanded to both sides through the cooperation of the driving block 502 and the driving rod 503.
