[0017] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] The present invention is an automatic lifting device for a motor stator. Figure 1 Combination Figure 2As shown, it is arranged corresponding to the roller shaft 1, including a power mechanism, a lifting mechanism and a driving mechanism, and the roller shaft 1 is used to transport the stator.

[0019] The power mechanism includes a driving base 2, a driving motor 3, a driving chain 4 and a driving shaft 5. The driving motor 3 is transversely arranged on the driving base 2 and the driving end drives the driving shaft 5 through the driving chain 4 to provide a main driving force.

[0020] The lifting mechanism includes a lifting seat 6, a transmission shaft 7, a linear bearing 8, a guide column 9 and a lifting platform 10. The two ends of the driving shaft 5 are respectively arranged on the driving base 2 and the lifting seat 6 through a bearing seat 11. The two sides of the transmission shaft 7 are also arranged on the lifting seat 6 through a bearing seat 11. The transmission shaft 7 is correspondingly connected to the driving shaft 5 through a transmission chain 12 to realize a driven driving force. There are multiple guide columns 9 and they are distributed on the lifting seat 6. The lifting platform 10 is slidably arranged on the guide columns 9 through linear bearings 8 to realize the directional movement of the lifting platform 10 in the longitudinal direction. Cams 13 are symmetrically arranged at both ends of the transmission shaft 7 and a supporting wheel 14 is arranged on the convex part of the cam 13. When the transmission shaft drives the cam to rotate, the supporting wheel 14 located on the convex part of the cam 13 contacts the lower surface of the lifting platform 10, and the lifting platform 10 is lifted up as the cam 13 rotates. The supporting wheel 14 plays a role in reducing friction and facilitating the lifting of the lifting platform 10.

[0021] The driving mechanism includes a support frame 15, a servo motor 16, a gear 17, a rack 18, a mounting seat 19, a linear guide 20 and a slider 21. The servo motor 16 is horizontally arranged on the top of the support frame 15 and a gear 17 is arranged on the driving end. The mounting seat 19 is arranged on the top of the support frame 15 and a slider 21 is arranged on the upper surface through the linear guide 20. The linear guide 20 and the movement direction of the roller shaft 1 are arranged perpendicular to each other. The edge side of the slider 21 is provided with a rack 18 parallel to the linear guide 20 and meshing with the gear 17 for transmission. The gear 17 is driven to rotate by the servo motor 16, and the gear 17 drives the rack 18 and drives the slider 21 to move laterally.

[0022] In addition, the mounting seat 19 is provided with a guide plate 22 located below the slider 21 on one side of the roller shaft 1 to facilitate the limiting guidance of the stator on the roller shaft 1 and prevent the stator from deviating and causing the lifting function to fail.

[0023] Working process:

[0024] 1. The initial state of lifting is as follows Figure 3 As shown in the figure, the sliders on both sides are at the origin and the lifting platform is at the low position. Figure 4As shown, after confirming the status, push the stator into the roller and place the stator in the center of the lifting platform. Press the extend button first, the servo motor will rotate a certain number of times in the set program, and the servo motor will extend a certain distance toward the stator through the gear drive rack. Then press the rise button, the drive motor drives the drive shaft to rotate through the drive chain, and the drive shaft drives the transmission shaft to finally drive the cam to rotate. Since the cam moves in a circle around the transmission shaft, the highest point of the cam will rise with the rotation, and the lifting platform supported by the support wheel of the cam convex part will also rise to the same height accordingly.

[0025] 2. After completing the above steps, the lifting status is as follows: Figure 5 As shown. At this time, the staff can take out the lower tray and place a new tray. After the replacement is completed, press the descending button, the drive motor drives the drive shaft to rotate through the drive chain, the drive shaft drives the transmission shaft and finally drives the cam to rotate. Since the cam moves in a circle around the transmission shaft, the highest point of the cam will decrease with the rotation. At this time, the lifting platform supported by the supporting roller will drop to the original height under the action of gravity due to the loss of the support of the supporting roller.

[0026] 3. After completing the above steps, the lifting status is as follows Figure 6 As shown. Press the return to origin button, and the servo motor retracts the slider under program control. At this time, the stator height is lowered, and the staff can push the stator to the next station.

[0027] The present invention is an automatic lifting device for a motor stator. The present invention reduces the risks brought by manual operation of the stator, reduces the influence of manual operation on the quality of the stator while ensuring safe production, and realizes the lifting and conveying functions of extremely heavy objects in a shorter time by utilizing a smaller space, thereby ensuring product quality, improving production efficiency, and ensuring the safety of production personnel.

[0028] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of by a person skilled in the art within the technical scope disclosed by the present invention without creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
