[0006] Preferably, the rotating assembly includes a rotating column, a worm gear, a fixed plate, a worm, and a reduction motor. The rotating column is rotatably mounted on the top of the base, and the top of the rotating column is connected to the mounting frame. The worm gear is fixedly sleeved on the outside of the rotating column. Two fixed plates are fixedly disposed on the top of the base, and a worm is rotatably mounted between the two fixed plates. The worm meshes with the worm gear. The reduction motor is disposed outside the fixed plate, and the output shaft of the reduction motor passes through the fixed plate and is connected to the worm.

[0007] Preferably, the base has a first annular groove at the top, and the mounting frame has support columns on both sides at the bottom, with the bottoms of the two support columns slidably disposed within the first annular groove.

[0008] Preferably, the base has connecting ears at each of its four bottom corners.

[0017] In this embodiment, based on the length of the worm to be processed, the drive motor 5 is started to drive the bidirectional screw 4 to rotate, which in turn drives the two moving plates 6 to move closer to each other, thus accommodating worms of different lengths. The two ends of the worm to be processed are clamped and fixed by the three-jaw chuck 7, which is used to accommodate worms of different diameters. The servo motor 8 is started to drive the adjacent three-jaw chuck 7 to rotate, thereby driving the worm to rotate. The rotation of the worm facilitates the grinding and polishing process of the worm.

[0018] The rotating assembly 2 includes a rotating column 21, a worm gear 22, a fixed plate 23, a worm 24, and a geared motor 25. The rotating column 21 is rotatably mounted on the top of the base 1, and the top of the rotating column 21 is connected to the mounting frame 3. The worm gear 22 is fixedly sleeved on the outside of the rotating column 21. Two fixed plates 23 are fixedly installed on the top of the base 1, and the worm 24 is rotatably mounted between the two fixed plates 23. The worm 24 is meshed with the worm gear 22. The geared motor 25 is located outside the fixed plate 23, and the output shaft of the geared motor 25 passes through the fixed plate 23 and is connected to the worm 24.

[0019] In this embodiment, the starting geared motor 25 drives the worm gear 24 to rotate, which in turn drives the rotating column 21 to rotate through the worm wheel 22, and finally drives the mounting frame 3 to rotate. The rotation of the mounting frame 3 allows the entire worm gear to be processed to rotate, thereby improving the flexibility of the positioning device and eliminating the need for frequent movement of the processing equipment for processing.

[0020] The base 1 has a first circular groove 12 on the top, and the mounting frame 3 has support columns 11 on both sides of the bottom. The bottom of the two support columns 11 is slidably set in the first circular groove 12.

[0021] In this embodiment, when the mounting frame 3 rotates, the two support columns 11 rotate within the first annular groove 12 to improve the stability of the rotation of the mounting frame 3.

[0022] The base 1 has connecting ears 10 at each of the four corners at the bottom.

[0023] In this embodiment, the connecting ears 10 at the four corners of the base 1 facilitate the installation of the device on a suitable position on the processing equipment by bolts.

[0024] The mounting frame 3 is equipped with a limit rod 9, and the movable plate 6 is slidably sleeved on the limit rod 9.

[0028] Working principle: The four connecting ears 10 at the four corners of the base 1 facilitate the installation of this device on a suitable position on the processing equipment using bolts. The worm gear 24 to be processed is placed between two three-jaw chucks 7. Depending on the length of the worm gear to be processed, the drive motor 5 is started to drive the bidirectional screw 4 to rotate, which in turn drives the two moving plates 6 to move closer to each other, thus accommodating worm gears of different lengths. The two ends of the worm gear to be processed are clamped and fixed by the three-jaw chucks 7 respectively. The three-jaw chucks 7 are used to accommodate worm gears of different diameters. The servo motor 8 is started to drive the adjacent three-jaw chucks 7 to rotate, thereby driving the worm gear to rotate. The rotation of the worm gear facilitates the grinding and polishing process of the worm gear.

[0029] The rotating component 2 can drive the mounting frame 3 and the worm gear inside it to rotate. Specifically, the geared motor 25 is started to drive the worm gear 24 to rotate, which in turn drives the rotating column 21 to rotate through the worm wheel 22, and finally drives the mounting frame 3 to rotate. The rotation of the mounting frame 3 allows the entire worm gear to be processed to rotate, thereby improving the flexibility of the positioning device and eliminating the need for frequent movement of the processing equipment to process it, thus improving the processing efficiency of the worm gear.
