[0029] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a crystal rod clamping and rotating device, including a support platform 1, a clamping device, and a rotating drive mechanism. A first sleeve 2 and a second sleeve 3 are respectively provided at both ends of the support platform 1. The first sleeve 2 and the second sleeve 3 have the same diameter, are horizontally coaxially arranged, and are rotatably connected to the support platform 1, respectively, for placing a crystal rod 17. The crystal rod 17 passes horizontally through the first sleeve 2 and the second sleeve 3, and is clearance-fitted with the first sleeve 2 and the second sleeve 3, with the cut end of the crystal rod 17 close to the second sleeve 3. To enable the first sleeve 2 and the second sleeve 3 to rotate synchronously, a horizontal connecting rod 4 is fixed between the first sleeve 2 and the second sleeve 3. The specific number of connecting rods 4 is not limited. Preferably, two horizontal connecting rods 4 are fixed between the first sleeve 2 and the second sleeve 3, symmetrically arranged on both sides of the crystal rod 17. The clamping device is provided on the connecting rods 4, for engaging the crystal rod 17 and fixing the crystal rod 17 to the first sleeve 2 and the second sleeve 3. A rotary drive mechanism is mounted on the support platform 1 to drive the first sleeve 2 and the second sleeve 3 to rotate simultaneously, thereby rotating the crystal rod 17. The entire device can both clamp and fix the crystal rod 17, making it easy to cut, and drive the crystal rod 17 to rotate, preventing the crystal rod 17 from chipping.

[0030] Specifically, to facilitate the installation of the first sleeve 2 and the second sleeve 3, a vertical first support frame 5 and a second support frame 6 are fixed on the support platform 1 at positions relative to the first sleeve 2 and the second sleeve 3, respectively. The first support frame 5 is provided with the first sleeve 2 and is rotatably connected to it, and the second support frame 6 is provided with the second sleeve 3 and is rotatably connected to it. Through holes are opened at the relative positions of the first support frame 5 and the second support frame 6. The first sleeve 2 is rotatably connected to the through hole of the first support frame 5 by a bearing, and the second sleeve 3 is rotatably connected to the through hole of the second support frame 6 by a bearing.

[0031] Specifically, to facilitate the installation of the connecting rod 4, the first sleeve 2 has a first protrusion 7 at one end near the connecting rod 4, and the second sleeve 3 has a second protrusion 8 at one end near the connecting rod 4. The two ends of the connecting rod 4 are respectively fixed to the first protrusion 7 and the second protrusion 8. The first protrusion 7 is integrally or separately fixedly connected to the first sleeve 2. The second protrusion 8 is integrally or separately fixedly connected to the second sleeve 3. The shapes of the first protrusion 7 and the second protrusion 8 are not limited; preferably, they are annular.

[0032] Specifically, the clamping device includes an opening and closing pressure plate 9, which is arranged circumferentially along the crystal rod 17. One end is rotatably connected to the connecting rod 4, and the other end is engaged with the connecting rod 4 on the opposite side. The shape of the opening and closing pressure plate 9 is not specifically limited; it can be set to an arc shape to fit the crystal rod 17, or it can be set to a semi-hexagonal shape, engaging the crystal rod 17 through three edges. The opening and closing pressure plate 9 has a certain degree of elasticity and can be made of PVC or PTFE material. The engaging end of the opening and closing pressure plate 9 and the connecting rod 4 is engaged by a buckle 10, which is convenient for disassembly and facilitates the handling of the crystal rod 17. The specific form of the buckle 10 is not limited, as long as it does not affect the rotation of the crystal rod 17. The specific number of clamping devices is not limited. Preferably, two clamping devices are provided between the first sleeve 2 and the second sleeve 3, one of which is located near the first sleeve 2 and the other near the second sleeve 3.

[0033] Preferably, the second sleeve 3 is provided with a holding device for holding the crystal rod 17. In some embodiments, the length of the crystal rod 17 is short enough to pass through both the first sleeve 2 and the second sleeve 3 simultaneously. When cutting the shorter crystal rod 17, the crystal rod 17 is passed through the second sleeve 3, and the holding device is used to hold and fix the crystal rod 17. The specific number of holding devices is not limited. Preferably, multiple holding devices are provided, and the multiple holding devices are evenly arranged along the circumference of the second sleeve 3.

[0034] Specifically, the supporting device includes a fixing block 11 and a supporting pin 12 threadedly connected to the fixing block 11. The fixing block 11 is fixed to the second sleeve 3. Preferably, the supporting pin 12 is configured as a supporting bolt. The fixing block 11 is fixedly connected to the second sleeve 3, and the supporting bolt is threadedly connected to the fixing block 11, passing through the fixing block 11 to support the crystal rod 17. The specific shape of the fixing block 11 is not limited, as long as it does not affect the rotation of the second sleeve 3 and the crystal rod 17.

[0035] Specifically, the rotation drive mechanism includes a drive motor 13, which is fixed on the side of the first support frame 5 away from the second support frame 6. The drive motor 13 can drive the first sleeve 2 to rotate, thereby driving the second sleeve 3 to rotate synchronously, causing the crystal rod 17 to rotate.

[0036] Specifically, a horizontal worm gear 14 is connected to the output shaft of the drive motor 13, and the worm gear 14 is positioned perpendicular to the axial direction of the first sleeve 2. A worm wheel 15 is fixed to the first sleeve 2 relative to the worm gear 14, and the worm gear 14 meshes with the worm wheel 15. The drive motor 13 drives the worm gear 14 to rotate, which in turn drives the worm wheel 15 to rotate, thereby causing the first sleeve 2 to rotate.

[0037] Preferably, the support platform 1 is equipped with rollers 16, which are positioned between the first support frame 5 and the second support frame 6. During cutting and loading, a trolley horizontally transports the crystal ingot 17 to the support platform 1, pushes the crystal ingot 17 onto the support platform 1, and passes it through the first sleeve 2 and the second sleeve 3. To facilitate the movement of the crystal ingot 17 between the first support frame 5 and the second support frame 6, rollers 16 are installed between the first support frame 5 and the second support frame 6. The specific form of the rollers 16 is not limited. When the crystal ingot 17 is placed on the first sleeve 2 and the second sleeve 3, there should be a small gap between the crystal ingot 17 and the rollers 16 to prevent the crystal ingot 17 from contacting the rollers 16 and affecting the rotation of the crystal ingot 17. The gap between the rollers 16 prevents interference with the clamping device when the crystal ingot 17 rotates.

[0038] Working process: Place the crystal rod 17 horizontally on the trolley, push the trolley to the end of the support platform 1 where the first sleeve 2 is located, and push the crystal rod 17 so that it passes through the first sleeve 2 and the second sleeve 3. The cutting end of the crystal rod 17 is positioned close to the second sleeve 3 and extends out of the second sleeve 3. The cutting equipment is positioned close to the second sleeve 3. After the cutting equipment completes the alignment, a clamping device is used to lock the crystal rod 17 into the first sleeve 2 and the second sleeve 3. Start the cutting equipment to begin cutting. After cutting to the middle position of the crystal rod 17, start the drive motor 13. The drive motor 13 drives the worm gear 14 and the worm wheel 15 to rotate, causing the first sleeve 2 and the second sleeve 3 to synchronously rotate the crystal rod 17 180°. The cutting end is manually supported with wood, and the cutting equipment is started again to cut the crystal rod 17 until the cutting is complete. If the crystal rod 17 is short, it is fitted inside the second sleeve 3 and fixed using a holding device.
