Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention, and to clearly and unequivocally define the scope of the present invention.

The invention relates to an automatic motor stator lifting device, which is arranged corresponding to a roller shaft 1 as shown in a figure 1 and a figure 2, and comprises a power mechanism, a lifting mechanism and a driving mechanism, wherein the roller shaft 1 is used for conveying a stator.

The power mechanism comprises a driving base 2, a driving motor 3, a driving chain 4 and a driving shaft 5, wherein 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 main driving force.

Elevating system includes jacking seat 6, transmission shaft 7, linear bearing 8, guide post 9 and elevating platform 10, the both ends of drive shaft 5 set up respectively on drive base 2 and jacking seat 6 through bearing frame 11, the both sides of transmission shaft 7 set up on jacking seat 6 through bearing frame 11 equally, transmission shaft 7 corresponds with drive shaft 5 through driving chain 12 and is connected the realization driven power of driving. The guide post 9 is provided with a plurality of and distributes and set up on jacking seat 6, elevating platform 10 slides through linear bearing 8 and sets up on guide post 9, realizes elevating platform 10 at fore-and-aft directional removal. The two ends of the transmission shaft 7 are symmetrically provided with cams 13, the convex parts of the cams 13 are provided with supporting wheels 14, when the transmission shaft drives the cams to rotate, the supporting wheels 14 positioned on the convex parts of the cams 13 are in contact with the lower surface of the lifting platform 10 and jack up the lifting platform 10 along with the rotation of the cams 13, and the supporting wheels 14 play a role in reducing friction and simultaneously facilitating the jacking up of the lifting platform 10.

Actuating mechanism includes support frame 15, servo motor 16, gear 17, rack 18, mount pad 19, linear guide 20 and slider 21, servo motor 16 transversely sets up and is provided with gear 17 in support frame 15 top and drive end, mount pad 19 sets up and is provided with slider 21 in support frame 15 top and upper surface through linear guide 20, linear guide 20 sets up with the direction of motion mutually perpendicular of roller 1, the border side of slider 21 is provided with rack 18 parallel with linear guide 20 and with gear 17 meshing transmission, drives gear 17 through servo motor 16 and rotates, gear 17 transmission rack 18 and drives slider 21 lateral shifting.

In addition, the installation seat 19 is provided with a guide plate 22 positioned below the sliding block 21 on one side of the roller shaft 1, so that the limiting and guiding of the stator on the roller shaft 1 are facilitated, and the jacking function failure caused by the deviation of the stator is prevented.

The working process is as follows:

1. the initial jacking state is shown in fig. 3, the sliders on two sides are located at the original points, and the lifting platform is located at the low position. After the state is confirmed, the stator is pushed into the roller, and the stator is placed at the center of the lifting platform, as shown in fig. 4. The stretching button is pressed first, the servo motor can rotate for a certain number of turns in a set program, and the servo motor drives the rack to stretch out for a certain distance towards the stator direction through the gear. And then the lifting button is pressed, the driving motor drives the driving shaft to rotate through the driving chain, and the driving shaft drives the driving shaft to finally drive the cam to rotate. Because the cam makes circular motion around the transmission shaft, the highest point of the cam can rise along with the rotation, and at the moment, the lifting platform supported by the riding wheel of the cam convex part can correspondingly rise to the same height.

2. After the above steps are completed, the jacking state is as shown in fig. 5. At this point the worker can take the tray below out and place a new tray. After the replacement is finished, the descending button is pressed down, the driving motor drives the driving shaft to rotate through the driving chain, and the driving shaft drives the driving shaft to finally drive the cam to rotate. Because the cam makes circular motion around the transmission shaft, the highest point of the cam can be lowered along with the rotation, and the lifting platform supported by the riding wheel can be lowered to the original height under the action of gravity due to the loss of the support of the riding wheel.

3. After the above steps are completed, the jacking state is as shown in fig. 6. And pressing a return-to-original-point button, and retracting the sliding block by the servo motor under the control of a program. At the moment, the height of the stator is reduced, and a worker can push the stator to the next station.

The invention relates to an automatic motor stator lifting and jacking device, which reduces risks brought by manual operation of a stator, ensures safe production, reduces the influence of manual operation on the quality of the stator, realizes the lifting function and the conveying function of extremely heavy objects in a shorter time by using a smaller space, ensures the quality of products, improves the production efficiency and ensures the safety of production personnel.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be made by those skilled in the art without inventive work within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
