Description

Technical Field

[0002] A material rotation mechanism is a device or structure that rotates materials on a plane. This rotation can be horizontal or vertical, or in other directions. It can be a simple object, such as a carousel, or a complex architectural structure, such as a spiral staircase. The design and application scope of the material rotation mechanism are extensive, and its application value in different fields is reflected from non-standard mechanical design to the spiral staircase of architectural structures.

[0003] To make the control of the rotation mechanism convenient and simple, a planar rotation mechanism for an automobile welding fixture (specifically refer to the patent number: 201810459021.8) appears, which includes a welding platform, a universal ball assembly, a bearing rotation mechanism, and a braking mechanism. The bearing rotation mechanism includes a connecting seat, a support disk, a bushing, and a single-direction thrust ball bearing. The connecting seat is fixedly installed on the welding platform. The support disk is installed at the top opening of the connecting seat, and the support disk rotates independently relative to the connecting seat. The bottom of the support disk is a rod-shaped structure and is embedded in the connecting seat. A bushing and a single-direction thrust ball bearing are installed between the rod-shaped structure and the connecting seat. The beneficial effect of the present invention is: simple structure. By setting the universal ball assembly, the rotating weight that the bearing rotation mechanism can bear can be increased, so that the maximum rotating weight can reach 600 kg, it can bear a certain eccentric force, and the service life of the bearing rotation mechanism is extended.

[0004] However, the rotation range of the existing rotation mechanism has certain limitations. It cannot appropriately adjust the rotation range according to the size of the material and the coverage range of the material, and it is easy for the material located at the rotation end to be affected by the surrounding environment (the rotation end rotates under force, the surrounding environment does not move, and one side of the material just contacts the surrounding environment), resulting in the rotation of the material being offset, causing the material to be unable to move along the predetermined trajectory, thereby reducing the utilization rate to a certain extent and increasing the difficulty of subsequent operations.

At the outer sides of the bottoms of the first rotating ring 2, the second rotating ring 3 and the third rotating ring 4, there are first toothed rings 402. On the side of the tops of the first rotating ring 2, the second rotating ring 3 and the third rotating ring 4 away from the first toothed ring 402, there are first annular chutes 403. The rotating assembly 5 includes a rotating disk 501. At the middle position of the bottom of the rotating disk 501, there is a rotating shaft 504.

On the side of the bottom of the rotating disk 501 close to the second toothed ring 503, there is a second annular chute 502. The first gear 106 is meshed with the second toothed ring 503. The second gears 107 are respectively meshed with the first toothed rings 402. At the bottom end of the outer side of the rotating disk 501, there is a second raised ring 505.

[0037] Please refer specifically to Figure 1 and 5 . At both sides of the tops of the three groups of pressing frames 109, there are pressing rods. Every two groups of pressing rods are respectively located at the bottom ends on both sides of the second gears 107 and are in contact with the second gears 107. At the bottom ends of the pressing frames 109 close to the motor 104 on one side, there are support rods, and the lengths of the support rods decrease sequentially from top to bottom.

[0038] Please refer specifically to Figure 1 、 2 、3, 4 and 5. The sliders 103 are matched with the first annular chutes 403 and the second annular chutes 502. The rotating disk 501, the first rotating ring 2, the second rotating ring 3 and the third rotating ring 4 are all slidably connected to the support columns 102 through the mutual cooperation of the sliders 103, the first annular chutes 403 and the second annular chutes 502, for the stable support of the sliding object, that is, it can make it slide normally and ensure the stability of its support.

The second gear 107 is movably connected to the rotating rod 105 through the activity hole. With the activity hole with an irregular structure and the section being the rotating rod 105 with an irregular structure, the second gear 107 can move better along the rotating rod 105. However, when the rotating rod 105 rotates, it can directly drive the second gear 107 to rotate synchronously, improving the utilization rate.

[0042] The working principle of the present utility model is as follows: When in use, the output end of the motor 104 rotates under the action of electricity, driving the rotating rod 105 and the first gear 106 to rotate. Since the first gear 106 is meshed and connected with the second toothed ring 503 on the rotating disk 501, the rotating disk 501 can be forced to rotate. Moreover, the second annular sliding groove 502 at the bottom of the rotating disk 501 slides along the top of the sliding groove, thereby realizing a stable parallel rotation operation. And when a large-range parallel rotation is required, the output end of the lowermost electric telescopic rod 108 can extend under the action of electricity, pushing the leftmost pressing frame 109 to move towards one side of the rotating disk 501, and making the pressing frame 109 drive the pressed first gear 106 to move leftward until the leftmost first gear 106 is meshed and connected with the corresponding first toothed ring 402, and driving the corresponding third rotating ring 4 to rotate simultaneously with the rotating rotating disk 501. Then, according to the size of the item to be rotated in parallel, the remaining two groups of second gears 107 are successively meshed and connected with the first toothed rings 402 on the first rotating ring 2 and the second rotating ring 3, directly driving the first rotating ring 2 and the second rotating ring 3 to rotate. Thus, the rotation range can be appropriately adjusted according to the size of the item, avoiding the phenomenon that the materials at the rotating end are affected by the surrounding environment and their rotation is offset, enabling the materials to move along the predetermined trajectory, thereby improving the utilization rate to a certain extent and reducing the difficulty of subsequent operations.

[0043] The above-mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
