[0026] The control mechanism includes a first motor 2 and a first lead screw 3 arranged on the base 1. The first motor 2 is used to drive the first lead screw 3. A sliding seat 5 is slidably mounted on the base 1. The sliding seat 5 and the first lead screw 3 form a screw pair. A supporting electric cylinder 6 is arranged on the sliding seat 5. A supporting roller 7 is arranged on the telescopic rod of the supporting electric cylinder 6 and is used to support the workpiece. A second motor 9 is arranged at the top end of the sliding seat 5, and a rotating electric cylinder 8 is rotatably mounted. A belt structure is arranged on the output shaft of the second motor 9 and is used to drive the rotating electric cylinder 8. A control shaft 10 is arranged on the telescopic rod of the rotating electric cylinder 8. A contact part 11 is arranged on the control shaft 10 and is used to contact the end face of the workpiece. A first signal transmitter 12 is arranged at one end of the control shaft 10, and a first signal receiver 14 is arranged on the end face of the mounting table 13. The first signal receiver 14 is opposite to the first signal transmitter 12. The first signal transmitter 12 is used to transmit position signals, and the first signal receiver 14 is used to receive position signals.

[0027] The first detection and contact mechanism includes a first electric cylinder 26 arranged on the mounting table 13. A first detection seat 27 is arranged on the telescopic rod of the first electric cylinder 26. A first contact part 28 is telescopically arranged on the first detection seat 27. A first displacement sensor 29 is arranged between the first contact part 28 and the telescopic rod of the first electric cylinder 26 and is used to output and feedback the telescopic signal of the first contact part 28. A contact ball 30 is arranged at the bottom end of the first contact part 28. A hole is arranged in the contact ball 30, and a second signal transmitter 32 is arranged inside the hole. A contact ball bearing 31 is arranged outside the hole. A second signal receiver 4 is arranged on the base 1. Signals are transmitted and received between the second signal receiver 4 and the second signal transmitter 32 to detect the hole position on the workpiece. The second detection and contact mechanism includes a second electric cylinder 22 arranged on the mounting table 13. A second detection seat 23 is arranged on the telescopic rod of the second electric cylinder 22. A second contact part 24 is telescopically arranged on the second detection seat 23.

Contact ball bearings 31 are also arranged at the bottom end of the second contact part 24 and are used to contact the surface of the workpiece.

[0028] Working principle: Place the bearing workpiece on the positioning mechanism, that is, the workpiece is located between the two positioning rods 16, and the push rod 21 is controlled to move by pushing the electric cylinder 20. The push rod 21 supports and positions the end face of the bearing; the drive disk 17 is controlled to rotate by controlling the motor 15, so that the radial screw 18 rotates, and then the positioning rod 16 moves, that is, the bearing is positioned.

[0029] When motor 2 works, screw rod 3 rotates, and then slide 5 moves. When motor 2 9 works, the electric cylinder 8 can be controlled to rotate, the control shaft 10 can be controlled to deflect, and the signal transmitter 12 transmits the position signal, which is received by signal receiver 14. When the signal transmitter 12 and the signal receiver 14 are relative to each other, the angle of the control shaft 10 can be determined, and then the control shaft 10 is controlled to move so that the control shaft 10 is located at the two circumferential sections of the bearing shell, the contact portion 11 contacts one end face of the bearing shell, and the push rod 21 contacts the other end face of the bearing shell.

[0030] The control shaft 10 is controlled to rotate, which drives the bearing to rotate. The bearing moves on the positioning mechanism, that is, the bearing moves between the two positioning rods 16. The contact part 28 is controlled by the electric cylinder 26 to contact the inner circumference of the bearing. As the workpiece rotates, the displacement sensor 29 can output a telescopic signal of the feedback contact part 28 to detect the size information of the inner side of the bearing, that is, the roundness and radial size; the electric cylinder 22 controls the movement of the contact part 24 and contacts the outer circumference of the workpiece. The displacement sensor 25 can output a telescopic signal of the feedback contact part 24 to detect the size information of the outer side of the bearing, that is, the roundness and radial size.

[0031] Furthermore, the signal transmitter 2 32 and the signal receiver 2 4 transmit and receive signals to detect the hole size information on the circumference of the bearing, that is, the signal transmitter 2 32 transmits the position signal and the signal receiver 2 4 receives the position signal. When the area where the position signal is transmitted is offset from the hole position, the signal cannot be transmitted between the signal transmitter 2 32 and the signal receiver 2 4. When the area where the position signal is transmitted corresponds to the hole position, the position signal can be transmitted and received, and from the signal being received to the signal being unacceptable, the hole size can be detected. After the detection is completed, the bearing is pushed out and positioned on the support roller 7 to achieve transfer.
