[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.

[0023] Example

[0024] Please refer to Figures 1 to 5. The present invention provides a technical solution: a quick positioning fixture for a single crystal silicon rod, including a worktable 1. An electric telescopic rod 3 is fixedly connected to the center of the upper surface of the worktable 1. A connecting column 4 is fixedly connected above the electric telescopic rod 3. Y-shaped placement frames 5 are fixedly connected to both sides above the connecting column 4. The worktable 1 has a sliding groove 101 inside. There are several sliding grooves 101, which are evenly distributed symmetrically at both ends of the worktable 1. A clamping plate movable frame 18 is slidably connected in the left sliding groove 101, and a fixed plate movable frame 6 is slidably connected in the right sliding groove 101. A fixing block 20 is fixedly connected to the bottom of the worktable 1. A bidirectional lead screw 19 is rotatably connected inside the fixing block 20. The lower end of the fixed plate movable frame 6 and the lower end of the clamping plate movable frame 18 are threaded to the outer surface of the bidirectional lead screw 19. A support column 2 is fixedly connected to the bottom of the worktable 1. There are several support columns 2, which are evenly distributed in a linear array at the bottom of the worktable 1.

[0025] Specifically, the sliding groove 101 enables the single-crystal silicon rod quick positioning fixture to achieve greater stability during the movement of the two movable frames. Through the coordinated arrangement of the electric telescopic rod 3 and the Y-shaped placement frame 5, the electric telescopic rod 3 can lift the Y-shaped placement frame 5 and then lift the single-crystal silicon rod during use, thereby completing clamping, inspection, and unloading operations. This makes clamping and unloading more convenient and faster, achieving the goal of making the device structure simpler and easier to use.

[0026] Please refer to Figures 1 to 5. A clamping disc rotating shaft 16 is rotatably connected above the movable frame 18 of the clamping disc. A handle 17 is fixedly connected to one side of the clamping disc rotating shaft 16, and a clamping disc 11 is fixedly connected to the other side of the clamping disc rotating shaft 16. Sleeves 10 are fixedly connected to both sides of the clamping disc 11. The cross-sectional shape of the sleeves 10 is semi-circular. A fixing plate 12 is fixedly connected inside the clamping disc 11. There are several fixing plates 12, which are evenly distributed in a circular array inside the clamping disc 11. A rotating shaft 14 is rotatably connected inside the fixing plate 12. An L-shaped clamping plate 13 is rotatably connected to the outer surface of the rotating shaft 14. A contact point 15 is fixedly connected to one end of the L-shaped clamping plate 13.

[0027] Specifically, through the cooperation of the clamping plate 11 and the L-shaped clamping plate 13, during use, the L-shaped clamping plate 13 can make the other end rotate around the fixed plate 12 as the rotation center after contacting the single crystal silicon rod, until the three contact points 15 contact the outer surface of the single crystal silicon rod for clamping. This makes clamping more convenient and facilitates subsequent removal and unloading, achieving the purpose of quick positioning, clamping, removal and unloading, while keeping the structure simple.

[0028] Please refer to Figures 1 to 5. A fixed plate 7 is fixedly connected to one side of the upper part of the fixed plate movable frame 6. A triangular chuck 8 is rotatably connected inside the fixed plate 7. Slide rods 9 are fixedly connected to both sides of the triangular chuck 8. The radial cross-sectional shape of the slide rods 9 corresponds to the radial cross-sectional shape of the sleeve 10. The slide rods 9 are slidably connected inside the sleeve 10.

[0029] Specifically, through the coordinated arrangement of the sleeve 10 and the slide bar 9, the single crystal silicon rod quick positioning fixture is equipped with the ability to connect the clamping plate 11 and the triangular chuck 8, and can also retract and extend during the clamping process, thereby completing the rotation inspection and polishing of the single crystal silicon rod after clamping, resulting in a simple structure.

[0030] In use, the monocrystalline silicon rod is first placed on the Y-shaped support frame. Then, the electric telescopic rod 3 is activated to lift the monocrystalline silicon rod. After lifting, one end of the monocrystalline silicon rod is clamped by the triangular chuck 8. After clamping, the bidirectional lead screw is rotated to bring the triangular chuck 8 and the clamping plate 11 closer together through the displacement of the fixed plate movable frame 6 and the clamping plate movable frame 18. This causes the other end of the monocrystalline silicon rod to contact the L-shaped clamping plate 13 inside the clamping plate 11. When the monocrystalline silicon rod contacts the L-shaped clamping plate 13, the L-shaped clamping plate 13 will rotate around the fixed plate 12 as the rotation center until the contact point 15 contacts the monocrystalline silicon rod. When the outer surface is exposed, the slide bar 9 will retract into the sleeve 10 due to the displacement of the two movable frames. After clamping, control the electric telescopic rod 3 to move downward. At this time, the clamping disc 11 can be rotated by rotating the clamping disc shaft 16 through the handle 17. The rotation of the clamping disc 11 drives the sleeve 10 to rotate, the rotation of the sleeve 10 drives the slide bar 9 to rotate, and the rotation of the slide bar 9 drives the triangular chuck 8 to rotate, thereby driving the clamped monocrystalline silicon rod to rotate. During the rotation, inspection and surface polishing can be performed. After inspection, the electric telescopic rod 3 is raised, the two movable frames are separated, and the monocrystalline silicon rod is removed from the triangular chuck 8.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
