[0006] Preferably, the sleeve is wrapped at the inner side position by arc frame when single crystal silicon rod is inserted into the inner position.
[0007] Preferably, the arc-shaped frame encloses the monocrystalline silicon rod at its internal position, and the contact between the arc-shaped frame and the monocrystalline silicon rod causes compression on the stainless steel spring A.
[0008] Preferably, the stainless steel spring A causes the arc-shaped frame to fit tightly against the outer wall of the monocrystalline silicon rod, and the monocrystalline silicon rod inside the arc-shaped frame causes the ball to rotate inside the arc-shaped frame when it moves.
[0009] Preferably, adjusting handles are fixed at both ends of the connecting rod, and the connecting rod can be moved by pulling the two adjusting handles.

[0014] Compared with the prior art, this utility model provides a fixture for positioning and cutting single-crystal silicon rods, which has the following beneficial effects:
[0015] 1. When adjusting the height of the sleeve, the connecting rod pulls two adjusting handles to move the insert post from the inside of the insertion hole to the outside. At the same time, the movement of the insert post causes the circular plate to compress the stainless steel spring B. In this way, the sleeve post can move up and down in the inside position of the fixed post. When the sleeve is adjusted to the appropriate height, the connecting rod is released to release the elastic force of the stainless steel spring B, and the insert post is re-inserted into the inside position of the insertion hole, so that the sleeve is maintained at the current height. By adjusting the height of the sleeve, the monocrystalline silicon rod is brought closer to the cutting tool, thus maintaining the cutting accuracy.
[0016] 2. The monocrystalline silicon rod is inserted into the inner position of the sleeve. An arc-shaped frame is set inside the sleeve. When the monocrystalline silicon rod enters the inner position of the sleeve, it comes into contact with the arc-shaped frame. The arc-shaped frame compresses the stainless steel spring A, thus making it tightly fit with the monocrystalline silicon rod. In this way, the arc-shaped frame can limit the movement of monocrystalline silicon rods of different sizes. At the same time, there are ball bearings inside the arc-shaped frame. The ball bearings ensure that when the arc-shaped frame limits the movement of the monocrystalline silicon rod, it does not affect the movement of the monocrystalline silicon rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] The utility model provides, for example Figures 1-4The fixture shown is for positioning and cutting monocrystalline silicon rods. It includes a support base plate 1, with fixing posts 2 fixed to the upper end of the support base plate 1 at positions on the left and right sides. A connecting post 3 is sleeved inside the fixing post 2. Multiple insertion holes 4 are distributed at the front end of the connecting post 3. A sleeve 7 for inserting the monocrystalline silicon rod is fixed to the upper end of the connecting post 3. Multiple stainless steel springs A10 are fixed to the inner wall of the sleeve 7. The other end of each stainless steel spring A10 is fixedly connected to an arc-shaped frame 6. Multiple integral... The ball bearings 5 are arranged in a straight line. A fixing cylinder 11 is fixed at the front end of the fixing column 2. An adjusting handle 8 is sleeved on the outside of the fixing cylinder 11. A connecting rod 9 is fixed on the inside of the adjusting handle 8. The adjusting handle 8 can pull the insertion column 14 fixed on the inside to move. A circular plate 13 is fixed on the outer wall of the insertion column 14. The movement of the circular plate 13 causes the insertion column 14 to compress the stainless steel spring B12 located at one end of the circular plate 13. A circular hole 15 is provided at the front end of the fixing column 2 at the upper position.
[0024] Insert the monocrystalline silicon rod into the inner position of the sleeve 7, and at the same time pull the connecting rod 9 outward to adjust the height of the sleeve 7. Send the monocrystalline silicon rod into the cutting platform of the cutting device, start the cutting device, and start cutting the monocrystalline silicon rod. After the cutting is completed, remove the monocrystalline silicon rod.
[0025] like Figure 2 and Figure 3 As shown, when the sleeve 7 is inserted into the inner position of the single crystal silicon rod, it is wrapped inside the sleeve 7 by the arc-shaped frame 6. The arc-shaped frame 6 wraps the single crystal silicon rod inside the sleeve, and the contact between the arc-shaped frame 6 and the single crystal silicon rod compresses the stainless steel spring A10. The stainless steel spring A10 makes the arc-shaped frame 6 fit tightly against the outer wall of the single crystal silicon rod. When the single crystal silicon rod inside the arc-shaped frame 6 moves, the ball bearing 5 rotates inside the arc-shaped frame 6.
[0026] The monocrystalline silicon rod is inserted into the inner position of the sleeve 7. An arc-shaped frame 6 is provided inside the sleeve 7. When the monocrystalline silicon rod enters the inner position of the sleeve 7, it comes into contact with the arc-shaped frame 6. The arc-shaped frame 6 compresses the stainless steel spring A10, thus making it tightly fit with the monocrystalline silicon rod. In this way, the arc-shaped frame 6 can limit the movement of monocrystalline silicon rods of different sizes. At the same time, a ball bearing 5 is provided inside the arc-shaped frame 6. The ball bearing 5 ensures that when the arc-shaped frame 6 limits the movement of the monocrystalline silicon rod, it does not affect the movement of the monocrystalline silicon rod.
[0027] like Figure 1 and Figure 4As shown, adjusting handles 8 are fixed at both ends of the connecting rod 9. The connecting rod 9 can be pulled to move the two adjusting handles 8. When the adjusting handles 8 are moved outward, the insertion post 14 moves from the inside position of the insertion hole 4 to the outside position. The movement of the insertion post 14 drives the circular plate 13 to move. The movement of the circular plate 13 compresses the stainless steel spring B12 located inside the fixed cylinder 11. When the insertion post 14 moves to the outside position of the insertion hole 4, the sleeve post 3 moves up and down inside the fixed post 2. The movement of the sleeve post 3 can change the height of the sleeve 7. The release of the elastic force of the stainless steel spring B12 allows the insertion post 14 to be inserted into the inside position of the insertion hole 4.
[0028] The two adjusting handles 8 are moved by pulling the connecting rod 9. The movement of the adjusting handles 8 causes the insertion post 14 to move from the inside position of the insertion hole 4 to the outside. At the same time, the movement of the insertion post 14 causes the circular plate 13 to compress the stainless steel spring B12. In this way, the sleeve post 3 can move up and down in the inside position of the fixed post 2. When the sleeve 7 is adjusted to the appropriate height, the connecting rod 9 is released to release the elastic force of the stainless steel spring B12. The insertion post 14 is re-inserted into the inside position of the insertion hole 4, so that the sleeve 7 is maintained at the current height.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
