[0020] By mounting the bearing on the outside of the positioning support plate 201, and then starting the drive motor 2031 to drive the drive shaft 2032 to rotate, the drive shaft 2032 drives the rotating belt disc 204 to rotate. Under the action of the limiting arc groove 2041, the rotating belt disc 204 causes the connecting protrusion 2022 to drive the movable slider 202 to move in the movable slide groove 2011.

[0024] A fixed support block 304 is provided at the bottom of the connecting right angle plate 303. A connecting support plate 3041 is fixedly connected to one end of the fixed support block 304, and a detection pressure plate 3042 is fixedly installed at the bottom of the connecting support plate 3041.
[0025] One end of the stabilizing bracket 3011 is fixedly connected to a fixed hinge 305. The fixed hinge 305 has a second shaft pin 3051 inside, and one end of the second shaft pin 3051 is fixedly connected to a limit protrusion 3052.
[0026] The second shaft pin 3051 has a lever sleeve 306 on its outer side, and a fixing protrusion 3061 is fixedly connected to the inner side of the lever sleeve 306. The second shaft pin 3051 has a sliding groove 3062, and the lever sleeve 306 is slidably installed in the sliding groove 3062 through the fixing protrusion 3061.
[0027] One end of the lever bushing 306 is fixedly connected to a pressure rod 307. A connecting outer ring 3071 is fixedly connected to the outside of the pressure rod 307. A connecting protrusion 3072 is fixedly connected to the top of the connecting outer ring 3071. A second through hole 3073 is provided on the connecting protrusion 3072. A steel wire rope 4 is provided between the second through hole 3073 and the first through hole 3024. A rubber sleeve 3074 is provided on the outside of the pressure rod 307.
[0028] A fixed bracket 308 is fixedly connected to one side of the stabilizing bracket 3011, and a clamping U-shaped bracket 3081 is fixedly connected to the fixed bracket 308.
[0029] A fixed vertical plate 309 is fixedly connected to one side of the fixed support 301. A connecting protrusion 3091 is fixedly connected to the middle of the fixed vertical plate 309. A connecting vertical rod 3092 is fixedly connected to the top of the connecting protrusion 3091. A first support block 3093 is provided on the outer side of the connecting vertical rod 3092. A first knob 3094 is provided on the first support block 3093. A connecting horizontal rod 3095 is provided on one side of the first support block 3093.

[0030] By pressing down on the pressure rod 307, the pressure rod 307 drags the steel wire rope 4 through the connecting protrusion 3072. The other end of the steel wire rope 4 pulls the fixing protrusion 3023, which in turn drives the moving belt plate 302 to move upward on the dovetail block 3015. At the same time, the moving belt plate 302 drives the detection pressure plate 3042 to move. Then, the weight of the moving belt plate 302 allows the detection pressure plate 3042 to fall freely, making it contact the top surface of the bearing. At the same time, the contact screw 3032 contacts the contact detection head 3097, and the height of the bearing can be directly read from the value on the detection instrument 3098. When the detection pressure plate 3042 is not to be lowered, the lever bushing 306 is moved to the innermost side of the second shaft pin 3051, which allows the pressure rod 307 to be locked in the mounting U-shaped frame 3081, preventing the detection pressure plate 3042 from falling.
[0031] The specific usage and function of this embodiment: In this invention, the bearing is mounted on the outside of the positioning support plate 201, and then the drive motor 2031 is started to drive the drive shaft 2032 to rotate. The drive shaft 2032 drives the rotating belt disc 204 to rotate. Under the action of the limiting arc groove 2041, the rotating belt disc 204 causes the connecting protrusion 2022 to move the movable slider 202 in the movable slide groove 2011. The movable slider 202 drives the inner support arc plate 2023 to internally support and position the bearing. On the one hand, this effectively avoids measurement errors caused by bearing displacement, ensuring the stability of bearing production quality from the source. On the other hand, by adjusting, it can quickly adapt to thrust self-aligning bearings of different diameters, greatly expanding the application range of the device. While improving detection accuracy, it significantly enhances the equipment's ability to meet diverse production needs. The system adapts to different bearing conditions. The weight of the movable belt plate 302 allows it to lower the testing pressure plate 3042, bringing it into contact with the top surface of the bearing. Simultaneously, the contact screw 3032 contacts the testing head 3097, allowing direct reading of the bearing height from the testing instrument 3098. When testing the next batch, the pressure rod 307 is pressed down, causing it to drag the steel wire rope 4 via the connecting protrusion 3072. The other end of the steel wire rope 4 pulls the fixing protrusion 3023, which in turn moves the movable belt plate 302 upwards on the dovetail block 3015. Simultaneously, the movable belt plate 302 raises the testing pressure plate 3042, allowing the tested bearing to be removed and a new bearing to be placed. Repeating this process completes the testing of a large batch of bearings.
