The vertical plate 2 is also provided with a limit component 5 for the bearing to be detected and a cleaning component 4 for cleaning the detected bearing.

[0029] Drive component 3: Figure 5 As shown, the roughness detector 6 is driven to move in the vertical direction to detect bearings of different diameters; the driving component 3 includes a mounting seat 31 and a slider 32, the mounting seat 31 is arranged on the workbench 1, the mounting seat 31 is provided with a mounting groove, a one-way screw 33 is rotatably connected in the mounting groove, the slider 32 is meshed on the one-way screw 33, the slider 32 is a rectangular block, and is slidably connected to the mounting seat 31 under the drive of the one-way screw 33, and does not rotate with the one-way screw 33. Under the drive of the one-way screw 33, the slider 32 slides up and down in the mounting groove, the one-way screw 33 is driven by a lifting motor 34, and the roughness detector 6 is mounted on the slider 32 by bolts.

[0030] Limiting component 5: Figure 3 As shown, it is used for supporting and limiting the bearing to be tested. The limit assembly 5 includes a bidirectional screw 53 and a limit plate 55. The back side of the vertical plate 2 is rotatably connected to the bidirectional screw 53 through a hinge seat 51. The bidirectional screw 53 is driven by a limit motor 52. The limit plate 55 is meshed on the bidirectional screw 53. The limit plates 55 are provided with two groups. Under the drive of the bidirectional screw 53, the limit plates 55 can move toward or away from each other and can be adapted to bearings of different diameters. A slide groove 22 is also provided on the vertical plate 2 for the limit plate 55 to slide. The limit plate 55 protrudes from the slide groove 22. The setting of the slide groove 22 can prevent the limit plate 55 from rotating along with the bidirectional screw 53 under the drive of the bidirectional screw 53.

[0031] One end of the limit plate 55 is located on the back of the vertical plate 2 and meshes with the bidirectional screw 53. The other end of the limit plate 55 protrudes from the slide groove 22 and is located in front of the vertical plate 2. The limit plate 55 and the facing surface of the bearing to be tested are also rotatably connected with a round roller 54. The setting of the round roller 54 facilitates the support of the bearing by the limit plate 55, and is used in conjunction with the cleaning component 4 to facilitate the driving roller 44 to drive the bearing to rotate and clean it.

[0032] Cleaning component 4: Figure 4 As shown, it is used to wipe and clean the bearing to prevent debris from adhering to the bearing and affecting the roughness detection; the cleaning component 4 includes a driving roller 44 and a wiping piece 45, and the vertical plate 2 is also provided with a cleaning groove 23, and a mounting plate 42 is provided in the cleaning groove 23. The workbench 1 is provided with a cylinder 41 that drives the mounting plate 42 to slide in the cleaning groove 23, and the mounting plate 42 is rotatably connected with a driving roller 44 that drives the bearing to be detected to rotate. The driving roller 44 is driven by a cleaning motor 43, and the mounting plate 42 is also provided with a wiping piece 45 for cleaning the bearing to be detected.

[0034] The bearing to be tested is mounted on two sets of limit plates 55, and the limit motor 53 is controlled to work and rotate, which drives the bidirectional screw 53 to rotate. Through the meshing relationship between the bidirectional screw 53 and the two sets of limit plates 55, the two sets of limit plates 55 are driven to move in opposite directions to support and limit the bearing. The cylinder 41 is controlled to work and extend, which drives the mounting plate 42 to slide upward in the cleaning tank 23, so that the driving roller 44 contacts the bearing. Since the wiping member 45 is higher than the driving roller 44 in the horizontal position, the wiping member 45 also contacts the bearing. The cleaning motor 43 is controlled to work and rotate, which drives the driving roller 44 to rotate, thereby driving the bearing to rotate. The friction between the bearing and the limit plate 55 can be reduced through the round roller 54, and the wiping block cleans the bearing.

[0035] After cleaning is completed, the lifting motor 34 is controlled to rotate, driving the one-way screw 33 to rotate. Through the meshing relationship between the one-way screw 33 and the slider 32, the slider 32 is driven to slide in the installation groove, thereby driving the roughness detector 6 to move in the vertical direction, corresponding to the position of the bearing to be tested, and controlling the roughness detector 6 to work and detect the roughness of the bearing.
