[0023] Refer to Figures 1-4, a two-axis slicing machine with multi-specification compatibility, including a frame body 1. The inner wall of the bottom of the frame body 1 is fixed with a frame 20 by bolts. The top of the frame 20 is fixed with a fixing frame 15 by bolts. A sliding frame 16 is slidably connected in the fixing frame 15. A plurality of uniformly and symmetrically distributed clamping pieces 18 are welded to the bottom of the sliding frame 16 and the inner wall of the bottom of the fixing frame 15. There are gaps between adjacent clamping pieces 18. The upper and lower opposite clamping pieces 18 are in contact and misaligned. An arc-shaped groove for clamping silicon rods of different specifications is formed on one side of each of the plurality of clamping pieces 18. A threaded hole is formed at the top of the fixing frame 15. A lead screw 17 is threadedly connected in the threaded hole, and the lead screw 17 is rotatably connected to the sliding frame 16. A cutting assembly for slicing the silicon rod is provided in the frame body 1. Place the silicon rod in the arc-shaped grooves on the plurality of clamping pieces 18 located below, and then rotate the lead screw 17. The lead screw 17 will move downward through the threaded engagement with the threaded hole, and the lead screw 17 will push the sliding frame 16 to move vertically downward on the fixing frame 15, so that the clamping pieces 18 on the sliding frame 16 clamp and fix the silicon rod. The arc-shaped groove can be used to place silicon rods of different specifications. And because the upper and lower opposite clamping pieces 18 are distributed in a contact and misaligned manner, the upper and lower opposite clamping pieces 18 can be overlapped in contact, so as to clamp and fix silicon rods of different specifications, improving the use effect of the slicing machine.

[0024] In the present utility model, the cutting assembly includes two connecting rods 6. Both of the two connecting rods 6 are arranged inside the frame body 1 and are respectively located on both sides of the frame body 1. Two guiding grooves are respectively formed on the inner walls of both sides of the frame body 1. The two connecting rods 6 move along the groove direction of the guiding grooves. An electric push rod 2 is fixed to the top of the frame body 1 by bolts. One end of the telescopic part of the electric push rod 2 passes through the frame body 1 and is fixed to a fixed frame 3 by bolts. Two U-shaped rods 4 are fixed to the bottom of the fixed frame 3 by bolts, and the U-shaped rods 4 are fixed to the connecting rods 6. Two L-shaped frames 5 are welded to the bottom of both of the two connecting rods 6. A shaft roller 11 is rotatably connected between two adjacent L-shaped frames 5. A plurality of diamond wires 14 for cutting silicon rods are wound between the two shaft rollers 11, and the diamond wires 14 pass through the gaps between a plurality of clamping pieces 18 located below. An adjusting assembly for changing the tightness of the diamond wires 14 is arranged at the top of the two connecting rods 6. A power assembly for driving the shaft roller 11 to rotate is arranged on one side of one of the L-shaped frames 5. The power assembly includes a motor. The motor is fixed to one side of one of the L-shaped frames 5 by bolts. One end of the output shaft of the motor passes through the L-shaped frame 5 and rotates with one of the shaft rollers 11. One end of both of the two shaft rollers 11 passes through the L-shaped frame 5 and is respectively key-connected with a driving pulley 12 and a driven pulley 13. A belt is wound between the driving pulley 12 and the driven pulley 13. By driving one of the shaft rollers 11 to rotate through the motor, one of the shaft rollers 11 drives the driving pulley 12 to rotate. The driving pulley 12 drives the driven pulley 13 to rotate through the belt, and the driven pulley 13 drives the other shaft roller 11 to rotate, so that the diamond wires 14 move around the shaft rollers 11. At the same time, by contracting the electric push rod 2, the fixed frame 3 is driven to move upward. The fixed frame 3 drives the U-shaped rods 4 to move upward. The U-shaped rods 4 drive the connecting rods 6 to move upward along the guiding grooves. The connecting rods 6 drive the shaft rollers 11 to move upward through the L-shaped frames 5, so that the diamond wires 14 move upward to cut the silicon rods. At the same time, since the upper and lower opposing clamping pieces 18 are fitted and misaligned, the clamping pieces 18 do not block the diamond wires 14;

[0025] The adjusting assembly includes two sliding grooves 7. The two sliding grooves 7 are respectively formed on one side of the two connecting rods 6. Two sliding blocks 8 are respectively slidably connected in the two sliding grooves 7. A tensioning roller 10 is rotatably connected between two opposing sliding blocks 8. A plurality of diamond wires 14 all bypass the two tensioning rollers 10. A bidirectional threaded rod 9 is rotatably connected in one of the sliding grooves 7, and the bidirectional threaded rod 9 passes through the two sliding blocks 8 and is threadedly connected with the two sliding blocks 8. By rotating the bidirectional threaded rod 9, the bidirectional threaded rod 9 drives the two sliding blocks 8 engaged with its thread to move in opposite or same directions along the sliding grooves 7. The two sliding blocks 8 respectively drive the two tensioning rollers 10 to move. Since the diamond wires 14 bypass the two tensioning rollers 10, the tightness of the diamond wires 14 is adjusted;

[0026] A plurality of tooth grooves 19 are formed in the circumferential outer walls of the two tension rollers 10 and the two shaft rollers 11. A plurality of diamond wires 14 are respectively located in the plurality of tooth grooves 19, so that the diamond wires 14 are located in the tooth grooves 19, thereby avoiding the deviation of the diamond wires 14 during the cutting of the silicon rod, so that the diamond wires 14 cut the silicon rod evenly and avoid uneven cutting thickness of the silicon rod. Wear-resistant coatings 21 are provided in the plurality of tooth grooves 19. Coating the wear-resistant coatings 21 in the tooth grooves 19 can increase the wear resistance of the shaft rollers 11, thereby reducing the wear of the diamond wires 14 on the shaft rollers 11. Knobs for rotating the bidirectional threaded rod 9 are welded to both ends of the bidirectional threaded rod 9 through the U-shaped rod 4.

[0027] Working principle: When in use, place the silicon rod in the arc-shaped grooves on the plurality of clamping pieces 18 located below, and then rotate the lead screw 17. The lead screw 17 will move downward through the thread engagement with the threaded hole, and the lead screw 17 will push the carriage 16 to move vertically downward on the fixed frame 15, so that the clamping pieces 18 on the carriage 16 clamp and fix the silicon rod. The arc-shaped grooves can be used to place silicon rods of different specifications, and since the upper and lower opposing clamping pieces 18 are arranged in a misaligned and overlapping manner, the upper and lower opposing clamping pieces 18 can be overlapped to clamp and fix silicon rods of different specifications, improving the use effect of the slicing machine. Then, drive one of the shaft rollers 11 to rotate through the motor. One of the shaft rollers 11 will drive the driving pulley 12 to rotate. The driving pulley 12 drives the driven pulley 13 to rotate through the belt, and the driven pulley 13 drives the other shaft roller 11 to rotate, so that the diamond wire 14 moves around the shaft roller 11. At the same time, the electric push rod 2 contracts to drive the fixed frame 3 to move upward. The fixed frame 3 drives the U-shaped rod 4 to move upward. The U-shaped rod 4 drives the connecting rod 6 to move upward along the guide groove. The connecting rod 6 drives the shaft roller 11 to move upward through the L-shaped frame 5, so that the diamond wire 14 moves upward to cut the silicon rod. At the same time, since the upper and lower opposing clamping pieces 18 are misaligned, the clamping pieces 18 will not block the diamond wire 14.

[0028] In addition, the terms "installation", "setting", "connection", and "socket connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
