[0002] A Chinese patent with announcement number CN116929285B discloses a corrugation detection mechanism for ring parts, wherein a detection unit is used to detect the corrugation of the ring workpiece, a first sensor is used to detect the connection horizontality of the ring workpiece, a transport unit is used to transport and move the ring workpiece, the transport unit includes a four-axis robot arm, a transport plate seat and a clamping cylinder, a discharge unit is arranged on one side of the transport unit, the discharge unit is used to discharge the pile of unqualified ring workpieces, the discharge unit includes a discharge box, a stacking plate, a pushing cylinder and a second sensor, the detection mechanism adopts a mechanical structure to replace manual movement of the ring workpiece, has a high degree of automation, and detects the placement horizontality of the ring workpiece through the first sensor.

[0003] The above-mentioned ring-type parts corrugation detection mechanism can detect the corrugation of annular workpieces, but there are still some defects in actual use: for example, when it is necessary to detect the bearing ring, because the outer wall (inner ring of the bearing) or the inner wall (outer ring of the bearing) of the bearing ring has a groove, the distance between the inner wall and the outer wall of the bearing ring (non-vertical surface) has a gradual value, and the outer ring corrugation probe and the inner ring corrugation probe in the above-mentioned ring-type parts corrugation detection mechanism are both fixed to the probe connection seat, so that the distance between the outer ring corrugation probe and the inner ring corrugation probe is a fixed value. Therefore, when the above-mentioned ring-type parts corrugation detection mechanism detects the groove of the bearing ring, when one of the corrugation probes contacts the groove, the other corrugation probe will collide with the workpiece. Therefore, the above-mentioned ring-type parts corrugation detection mechanism can only detect the vertical surface of the bearing ring, but cannot perform corrugation detection on the groove of the bearing ring, and the detection effect is not good;

[0004] Furthermore, when the ring-like workpiece is fixed by the above-mentioned ring-like parts waviness detection mechanism, the air film clamp is used to fix the ring-like workpiece, thereby making it impossible to perform waviness detection on the surface of the ring-like workpiece in contact with the air film clamp.

[0071] The clamping and rotating mechanism 204 includes a vertical seat 2041, which is fixedly installed on the second mounting frame 201. At the upper end of the vertical seat 2041, a U-shaped seat 2043 is fixedly installed. On one side of the U-shaped seat 2043, a second motor 2044 is fixedly installed. Inside the U-shaped seat 2043, a second lead screw 2045 is rotatably connected. The rotating shaft of the second motor 2044 is fixedly connected to one end of the second lead screw 2045.

[0080] By adopting the above technical solution, when a defective bearing ring 4 is detected, the conveying mechanism 1 moves the defective bearing ring 4 to the storage rod 304. When the material sensing sensor 307 detects that the defective bearing ring 4 on the storage rod 304 is full, the piston rod of the second electric push rod 305 is extended to move the storage rod 304 storing the defective bearing ring 4 to the material removal point, and the defective bearing ring 4 is manually removed from the storage rod 304.
