The output direction of the positioning cylinder 3 points to the roller 6. When the positioning cylinder 3 works, it can drive the positioning assembly 4 to approach or move away from the roller 6, so as to realize the clamping or releasing of the workpiece by reducing or expanding the distance between the positioning assembly 4 and the roller 6.

[0022] Further, the positioning assembly 4 comprises a positioning plate 41 and two positioning wheels 42. The leading end of the positioning plate 41 is in a U-shaped structure, that is, the inner arc of the leading end of the positioning plate 41 faces the roller 6.

The trailing end of the positioning plate 41 is fixedly connected with the output end of the positioning cylinder 3. The two positioning wheels 42 are at the same horizontal height as the roller 6. The length direction of the positioning plate 41 is the same as the output direction of the positioning cylinder 3. Further, the two positioning wheels 42 are arranged along the inner arc of the leading end of the positioning plate 41.

[0023] In an embodiment, in order to avoid damage to the surface of the bearing ring, the positioning wheel 42 and the roller 6 are both made of polyurethane material.

[0028] The working principle of the detection mechanism is as follows: when the sensor detects that the bearing ring is conveyed to the position of the positioning assembly 4, the conveying belt is paused, the positioning cylinder 3 works to make the two positioning wheels 42 push the bearing ring to approach the roller 6 until the positioning is completed, then the driving motor 5 drives the roller 6, under the action of friction, the bearing ring rotates circumferentially between the roller 6 and the positioning wheel 42, at this time, the outer ring detection assembly 7 and the inner ring detection assembly 8 detect the smoothness and roughness of the outer ring and the inner ring of the bearing ring respectively and transmit to the control system for comparison, the control system automatically determines whether the bearing ring is qualified or not, after completion, the positioning cylinder 3 drives the positioning wheel 42 to return to the initial position, the conveying belt 2 starts to continue conveying the bearing ring to the rejection mechanism, the rejection mechanism will reject the unqualified workpiece from the conveying belt, while the rejection mechanism does not act on the qualified workpiece, the conveying belt 2 discharges the detected bearing ring from the mechanism.
