The operator will turn the taken out bearing over and reinsert it into the inner side of the work seat 35. If the bearing has completed the assembly of the sealing rings on both sides, the new bearing will be placed on the inner side of the work seat 35. At the next workstation, the sealing ring is placed on the bearing, and finally enters the assembly station to realize automatic assembly and testing. The above process is repeated to realize continuous processing of the bearing, which greatly improves the assembly efficiency.

[0041] The bearing press-fit assembly device for mechanical motor processing places the bearing inside the tooling seat 35. The bearing is surrounded by the clamping plate 42. The spring set between the clamping plate 42 and the connecting seat 41 drives the clamping plate 42 to fix the bearing. At the next station, the sealing ring is placed on the bearing, and finally enters the assembly station.

[0042] The telescopic controller 12 drives the lifting column 10 to move downward, and the lifting column 10 drives the pressing plate 11 to move downward. During the downward movement of the pressing plate 11, the bottom rod 16 first inserts into the inner ring of the bearing, and the bottom end abuts against the tooling seat 35. As the pressing plate 11 continues to move downward, the connecting rod 13 drives the gear seat 15 to move downward, and the gear seat 15 cooperates with the transmission gear 18 to drive the rotating rods 17 on both sides to rotate. The rotating rod 17 drives the locking frame 19 to expand outward, and the locking frames 19 on both sides cooperate with each other to complete the locking of the inner ring of the bearing. At this time, the pressing plate 11 has not yet performed the pressing operation, and the pressing plate 11 continues to move downward. The gear seat 15 no longer moves, and the connecting rod 13 is inserted downward into the inner side of the bottom rod 16. The pressing plate 11 is evenly in contact with the bearing, completing the assembly of the bearing and the sealing ring;

[0043] When the lifting column 10 moves downward, it will drive the cooperative plate 21 to move synchronously. The cooperative plate 21 cooperates with the fixed rod 22 to drive the energy transmission member 23 to move inside the energy transmission tube 24, driving the sensing member 26 inside the other end of the energy transmission tube 24 to move accordingly. The sensing member 26 drives the transmission control plate 25 to move. The transmission control plate 25 drives the lifting plate 27 to move upward along the guide rod 30 through the push-pull rod 28. The lifting plate 27 drives the piston member 29 to insert into the inner side of the opposite drive control tube 37. The third piston can control the air inside the drive control tube 37 to enter the inner side of the connecting chamber 36. The air inside the connecting chamber 36 enters the inner side of the retractable tube 38, driving the retractable member 39 to move inside the retractable tube 38. The retractable member 39 drives the connecting seat 41 to move toward the side close to the clamping plate 42, so that the clamping plate 42 can fully fix the outer ring of the bearing.

[0044] After the pressing is completed, the pressing plate 11 is lifted and separated from the bearing, and the test motor 8 drives the driving rod 9 to rotate. The driving rod 9 cooperates with the telescopic controller 12 to drive the lifting column 10 to rotate synchronously. The lifting column 10 cooperates with the pressing plate 11 and the locking frame 19 to drive the inner ring of the bearing to rotate, thereby testing the assembled bearing. Subsequently, the pressing plate 11 continues to move upward, and the locking frame 19 releases the fixation on the inner ring of the bearing and is withdrawn from the bearing.

[0045] The switching motor 31 cooperates with the pulley and belt to realize the rotation of the control column 32. The control column 32 drives the support plate 34 to rotate, and switches the position of the tooling seat 35 on the support plate 34. The lifting controller 44 drives the ejection plate 43 to move upward. The ejection plate 43 ejects the bearing slightly and then resets it. When entering the next workstation, it is convenient for the operator to take it out. The operator will turn the taken out bearing over and reinsert it into the inner side of the tooling seat 35. If the bearing has been assembled with sealing rings on both sides, the new bearing will be placed on the inner side of the tooling seat 35. At the next workstation, the sealing ring is placed on the bearing, and finally enters the assembly station and repeats the above process to achieve continuous processing of the bearing.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
