[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a hollow rotary platform, including a support 1 and an adjustable mounting mechanism 4;

[0022] Support 1: A guide cylinder 2 is fixedly connected to its upper end, and a turntable 5 is rotatably connected inside the guide cylinder 2. A controller 12 is set on the right side of the support 1, and the input end of the controller 12 is electrically connected to an external power source.

[0023] Adjustable mounting mechanism 4 includes an adjustment chamber 41, a rotating shaft 42, and an arc-shaped mounting plate 46. The adjustment chamber 41 is fixedly connected to the upper end of the turntable 5. The interior of the adjustment chamber 41 is rotatably connected to evenly distributed rotating shafts 42. The upper ends of each rotating shaft 42 are fixedly connected to arc-shaped mounting plates 46, which have evenly distributed mounting holes. The adjustable mounting mechanism 4 also includes a first pulley 43, an auxiliary shaft 44, and a second pulley 45. The first pulley 43 is fixedly connected to the middle of the rotating shaft 42. The auxiliary shaft 44 is rotatably connected to the interior of the adjustment chamber 41. The upper ends of each auxiliary shaft 44 are fixedly connected to the second pulley 45. The second pulley 45 and the first pulley 43 are connected by the same transmission belt. The adjustable mounting mechanism 4 also includes a drive shaft 47 and a drive knob 48. The drive shaft 47 is rotatably connected to the left end of the adjustment chamber 41, and the lower end of the drive shaft 47 is fixedly connected to a drive gear. Wheel 2, the lower end of the leftmost rotating shaft 42 is fixedly connected to the driven gear 2, the driving gear 2 and the driven gear 2 are meshed together, and the upper end of the driving shaft 47 is fixedly connected to the driving button 48. According to the diameter of the crucible support, the driving shaft 47 is rotated by the driving button 48. The rotation of the driving shaft 47 drives the driving gear 2 to rotate, which in turn drives the left rotating shaft 42 to rotate. The rotation of the left rotating shaft 42 drives the vertically adjacent pulley 1 43 to rotate. Under the transmission action of the transmission belt, the pulley 1 43 and pulley 2 45 rotate synchronously, which in turn makes the four rotating shafts 42 rotate synchronously. The rotation of the rotating shafts 42 drives the vertically adjacent arc-shaped mounting plate 46 to rotate. When the arc-shaped mounting plate 46 reaches the required position, the rotation of the driving shaft 47 stops. Then, the threaded hole of the crucible support is stably connected to the mounting hole inside the arc-shaped mounting plate 46 by screws, thereby realizing the stable installation of the crucible.

[0024] Wherein: a drive chamber 3 is provided at the right end of the upper surface of the support 1, the guide cylinder 2 is connected to the drive chamber 3, a driven gear 1 is fixedly connected to the lower end of the outer surface of the turntable 5, a drive shaft 6 is rotatably connected to the right end of the drive chamber 3, a drive gear 7 is fixedly connected to the upper end of the drive shaft 6, the drive gear 7 and the driven gear 1 are meshed, a motor 11 is provided at the right end of the lower surface of the support 1, the upper end of the output shaft of the motor 11 is fixedly connected to the lower end of the drive shaft 6, the input end of the motor 11 is electrically connected to the output end of the controller 12, the controller 12 realizes the operation of the motor 11, the output shaft of the motor 11 rotates to drive shaft 6 rotates, drive shaft 6 rotates to drive gear 7 rotates, and then drives driven gear 1 to rotate, thus realizing the turntable 5 to rotate under the guidance of the guide cylinder 2, the rotation of the turntable 5 drives the adjustment chamber 41 to rotate, and the rotation of the adjustment chamber 41 drives the crucible to rotate through the arc-shaped mounting 46;

[0025] The drive chamber 3 is rotatably connected to a driven shaft 8 at its left end. A measuring gear 9 is fixedly connected to the upper end of the driven shaft 8. The measuring gear 9 meshes with the driven gear 1. An angle sensor 10 is installed at the front end of the lower surface of the bracket 1. The upper end of the input shaft of the angle sensor 10 is fixedly connected to the lower end of the driven shaft 8. The angle sensor 10 is bidirectionally electrically connected to the controller 12. The rotation of the driven gear 1 drives the measuring gear 9 to rotate. The rotation of the measuring gear 9 drives the driven shaft 8 to rotate. The rotation of the driven shaft 8 drives the input shaft of the angle sensor 10 to rotate. The angle sensor 10 monitors the rotation angle information of the turntable 5 in real time and sends the angle information to the signal receiving end of the controller 12 in real time.

[0026] The working principle of the hollow rotary platform provided by this utility model is as follows: During operation, the operator first stably installs the bracket 1 and guide cylinder 2 into the working area. After stable installation, the operator rotates the drive shaft 47 through the drive button 48 according to the diameter of the crucible bracket. The rotation of the drive shaft 47 drives the drive gear 2 to rotate, which in turn drives the driven gear 2 to rotate, thereby driving the left rotating shaft 42 to rotate. The rotation of the left rotating shaft 42 drives the vertically adjacent pulley 43 to rotate. Under the transmission action of the transmission belt, the pulley 43 and pulley 45 rotate synchronously (the pulley 43 and the four pulleys 45 are distributed at four points to achieve transmission through the transmission belt), thereby causing the four rotating shafts 42 to rotate synchronously. The rotation of the rotating shafts 42 drives the vertically adjacent arc-shaped mounting plate 46 to rotate. When the arc-shaped mounting plate 46 reaches the desired position, the operator stops rotating the drive shaft 47 and then screws the threaded holes of the crucible bracket into place. The crucible is stably connected to the mounting holes inside the arc-shaped mounting plate 46, thereby achieving stable installation (after the four arc-shaped mounting plates 46 are connected to the crucible support, they mutually restrict each other to prevent the four rotating shafts 42 from rotating). During operation, the operator controls the motor 11 through the controller 12. The output shaft of the motor 11 rotates, driving the second drive shaft 6 to rotate. The second drive shaft 6 rotates, driving the drive gear 7 to rotate, which in turn drives the driven gear 1 to rotate. This causes the turntable 5 to rotate under the guidance of the guide cylinder 2. The rotation of the turntable 5 drives the adjustment chamber 41 to rotate. The rotation of the adjustment chamber 41 drives the crucible to rotate through the arc-shaped mounting plate 46. At the same time, the rotation of the driven gear 1 drives the measuring gear 9 to rotate. The rotation of the measuring gear 9 drives the driven shaft 8 to rotate. The rotation of the driven shaft 8 drives the input shaft of the angle sensor 10 to rotate. The angle sensor 10 monitors the rotation angle information of the turntable 5 in real time and sends the angle information to the signal receiving end of the controller 12 in real time.

[0027] It is worth noting that the angle sensor 10 disclosed in the above embodiments can be a WDD-320°-1K angle sensor, and the controller 12 controls the operation of the angle sensor 10 and the motor 11 using methods commonly used in the prior art.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
