DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] Example 1: A heavy-duty workpiece indexing and rotating mechanism, such as Figures 1-5 As shown, it includes a scale base 1, a rotating ring 2, a pointer 21, a supporting plate 3, a worm gear 4, a driving motor 5, a worm 6, a lifting assembly and an auxiliary assembly. The scale base 1 is rotatably connected to the rotating ring 2, the pointer 21 is fixedly connected to the right side of the rotating ring 2, the upper side of the rotating ring 2 is fixedly connected to the supporting plate 3, the lower center position of the supporting plate 3 is fixedly connected to the worm gear 4, the scale base 1 is fixedly connected to the driving motor 5, the output shaft of the driving motor 5 is fixedly connected to the worm 6, the worm 6 is engaged with the worm gear 4, the supporting plate 3 is provided with a lifting assembly for controlling the lifting of heavy workpieces, and the lifting assembly is provided with an auxiliary assembly for assisting the loading and unloading of heavy workpieces.

[0022] When using this device, the staff uses the auxiliary component to assist the heavy workpiece to move to the lifting component. The lifting component can control the lifting and adjusting height of the heavy workpiece, and the rotation of the output shaft of the drive motor 5 can drive the worm 6 to rotate, the rotation of the worm 6 drives the worm wheel 4 to rotate, and the rotation of the worm wheel 4 drives the support plate 3 to rotate. The rotation of the support plate 3 drives the heavy workpiece to rotate and adjust the angle through the lifting component. When the support plate 3 rotates, the rotating ring 2 will also rotate. The pointer 21 cooperates with the scale base 1 to facilitate the staff to accurately adjust the angle of the heavy workpiece. In this way, the heavy workpiece can be controlled to perform precise rotation adjustment at any angle for processing.

[0023] Example 2: Based on example 1, as shown in Figure 1 and Figure 4 The lifting assembly includes support frames 7, rotating rods 8, winding wheels 9, speed reduction motors 10, steel wires 11 and lifting plates 12. The support frames 7 are fixedly connected to the left and right sides of the supporting plate 3. The rotating rods 8 are rotatably connected between the upper parts of the left and right support frames 7. The winding wheels 9 are fixedly connected to the left and right parts of the rotating rods 8. The speed reduction motors 10 are fixedly connected to the upper parts of the right support frames 7. The output shafts of the speed reduction motors 10 are fixedly connected to the rotating rods 8. The steel wires 11 are wound around the left and right winding wheels 9. The lifting plates 12 are fixedly connected between the ends of the left and right steel wires 11. The lifting plates 12 are placed on the supporting plate 3. The central parts of the lifting plates 12 are hollow structures.

[0024] As shown in Figure 1 and Figure 5 The auxiliary assembly includes first extension plates 13 and second extension plates 14. The first extension plates 13 are rotatably connected to the front and rear sides of the lifting plates 12. The second extension plates 14 are rotatably connected to the sides of the first extension plates 13 away from the lifting plates 12. Three equidistantly distributed rollers are rotatably connected to the second extension plates 14 and the first extension plates 13. Arc-shaped grooves are formed in the sides of the second extension plates 14 away from the first extension plates 13.

[0025] When the device is used, the workers pull the second extension plates 14 outward through the arc-shaped grooves, and the first extension plates 13 also rotate outward. At this time, the first extension plates 13 and the second extension plates 14 are connected to the ground and the lifting plates 12. The workers can push the heavy large workpieces onto the second extension plates 14. The second extension plates 14 and the first extension plates 13 cooperate to assist the loading and unloading operations of the heavy large workpieces. The rollers can reduce the friction between the heavy large workpieces and the second extension plates 14 and the first extension plates 13, so that the workers can more easily push the heavy large workpieces. After the heavy large workpieces are pushed onto the lifting plates 12, the workers can process the heavy large workpieces. Since the lifting plates 12 are hollow structures, the debris generated during processing can leak downward for cleaning. When processing, the speed reduction motors 10 operate to drive the rotating rods 8 to rotate. The rotating rods 8 drive the winding wheels 9 to rotate. The winding wheels 9 wind the steel wires 11, thereby pulling the lifting plates 12 upward. Conversely, the winding wheels 9 can unwind the steel wires 11, thereby driving the lifting plates 12 and the heavy large workpieces to move downward. In this way, the height of the heavy large workpieces can be adjusted for processing.
