One end of the connecting rod 15 is rotatably connected to the radial seat 21. Two positioning seats 22 are slidably mounted on the radial seat 21. Guide wheels 26 and a guide wheel motor 23 are arranged on the positioning seats 22. The guide wheel motor 23 is used to drive the guide wheels 26; a first spring 24 is connected between the two positioning seats 22; a contact block 25 is arranged on the side of the positioning seat 22. A telescopic frame 27 is telescopically arranged on the side of the radial seat 21. A contact shaft 28 is arranged on the telescopic frame 27, and a contact wheel 29 is arranged on the telescopic frame 27. The contact wheel 29 is used to push the contact block 25. A second spring 30 is connected between the telescopic frame 27 and the radial seat 21; a bevel turntable 33 is rotatably mounted on the radial seat 21. A bevel end face is arranged on the bevel turntable 33. The bevel end face contacts the contact shaft 28; a clamping gear 34 is also rotatably connected to the radial seat 21. A rack 31 is slidably mounted on the positioning table 16. A third spring 35 is connected between the rack 31 and the positioning table 16. A contact rod 32 is arranged at one end of the rack 31. The rack 31 meshes with the clamping gear 34. An electromagnetic clamping plate is arranged inside the clamping gear 34. The electromagnetic clamping plate clamps and fixes the end shaft of the bevel turntable 33 to drive the bevel turntable 33 to rotate synchronously; a control ring 17 is rotatably mounted on the positioning table 16, and a control motor 18 is fixedly arranged. A control gear 19 is arranged on the output shaft of the control motor 18. The control gear 19 meshes with the control ring 17, and a push wheel 20 is arranged on the control ring 17.

[0028] The detection mechanism includes a detection electric cylinder 38 arranged on the positioning table 16. A surrounding ring 39 is arranged on the telescopic rod of the detection electric cylinder 38. A contact sensor 40 is arranged inside the surrounding ring 39. The contact sensor 40 contacts the annular workpiece. By controlling the rotation of the annular workpiece, the contact sensor 40 generates a telescopic displacement to output and feedback the dimensional information of the annular workpiece.

[0029] Operating principle: Place the annular workpiece on the turntable 3. Control the movement of the positioning shaft 9 through the first electric cylinder 8. The positioning shaft 9 positions the workpiece. The first motor 2 controls the turntable 3 to flip so that the workpiece faces the clamping and fitting mechanism. The third motor 6 can work, the third lead screw 7 rotates, the first sliding seat 10 moves, and the second electric cylinder 11 controls the movement of the push plate 12. The push plate 12 can push the workpiece as a whole, that is, make each workpiece lean against as a whole.

[0030] By controlling the movement of the push plate 12, the workpieces can also be pushed one by one. The second motor 4 works, the second lead screw 5 rotates, the positioning table 16 moves, the positioning electric cylinder 36 controls the movement of the second positioning shaft 37, and the workpiece can be transferred to the second positioning shaft 37 for positioning; and the workpiece is located on each positioning mechanism. Specifically, the workpiece is located between two guide wheels 26. That is, by controlling the electric rod 13 to control the movement of the connecting plate 14, under the connection action of the connecting rod 15, the radial seat 21 moves, that is, the positions of the two guide wheels 26 are adjusted. When the radial seat 21 moves, the clamping gear 34 meshes with the rack 31 to achieve self-rotation; when the workpiece is between the two guide wheels 26, by controlling the 18th motor to work and controlling the rotation of the control ring 17, the push wheel 20 pushes the contact rod 32, that is, the rack 31 moves. At this time, the electromagnetic clamp inside the clamping gear 34 clamps the rotating shaft of the inclined surface turntable 33 to drive the inclined surface turntable 33 to rotate synchronously. The inclined end surface of the inclined surface turntable 33 contacts the contact shaft 28, which can push the telescopic frame 27 to move, and then the contact wheel 29 pushes the contact block 25, and the positioning seat 22 slides, so that each guide wheel 26 limits the workpiece.

[0031] Furthermore, the guide wheel motor 23 drives the guide wheel 26 to rotate the annular workpiece. The detection electric cylinder 38 controls the movement of the surrounding ring 39. The annular workpiece is located inside the surrounding ring 39. The contact sensor 40 contacts the annular workpiece. As the annular workpiece rotates, the contact sensor 40 generates a telescopic displacement to output and feedback the dimensional information of the annular workpiece. If there are concavo-convex deformations on the annular workpiece, the contact sensor 40 generates a telescopic displacement, and the dimensional information of the workpiece surface can be output and feedback.
