Under the action of the thread, the clamping seat 205 on the first slider 204 can be driven to move toward the placement plate 400 to achieve left and right limit of the bearing. The upper clamping assembly 300 includes a fixed block 301 symmetrically arranged at the upper end of the detection table 100, and a second motor 302 is provided at the upper end of the two fixed blocks 301. A second slide groove 303 is opened on the relative inner side surfaces of the two fixed blocks 301, and a second slider 305 is slidably connected in the second slide groove 303. A threaded rod 304 is fixedly connected to the output shaft of the second motor 302, and the threaded rod 304 is threadedly connected to the second slider 305. The staff can start the second motor 302 to rotate the threaded rod 304. Under the action of the thread, the electric push rod 306 can be driven up and down by the second slider 305 to adjust the clamping height according to the size of the bearing.
[0023] According to another embodiment of the present invention, Figure 1-3As shown, a clamping surface 206 is provided in the clamping seat 205, and bolts 207 are provided on the front and rear sides of the two clamping seats 205. A clamping plate 208 is provided on the bolt 207, so that the clamping surface 206 contacts the left and right sides of the bearing to limit the bearing. After that, the staff can rotate the bolt 207 to make the clamping plate 208 continuously move toward the inside of the clamping seat 205 until it contacts the bearing, and clamp the front and rear sides of the bottom of the bearing. The bolt 207 is threadedly connected to the clamping seat 205, and the bolt 207 is rotatably connected to the clamping plate 208.
