Description

Technical Field

[0001] This utility model relates to the field of silicon core beam processing technology, specifically a clamping fixture with correction and positioning function. Background Technology

[0002] Silicon core beams are mainly used in polysilicon production equipment (such as reduction furnaces) and are key components that support the silicon cores and ensure their verticality. The silicon core beams are typically mounted on a graphite base in the reduction furnace, and are assembled with the silicon cores, electrode disks, and other components using robotic arms and clamping devices. During processing, the silicon core beams require drilling holes using a drilling device.

[0003] Current drilling equipment is prone to drilling position deviations due to the positioning problem of the fixture during the drilling process. This is mainly because the clamping fixture can only clamp and fix the silicon core beam, but cannot correct misaligned silicon core beams, resulting in inaccurate positioning during drilling.

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.

[0015] This utility model provides a technical solution: like Figures 1-5 The clamping fixture shown includes a base 1, with punching components 2 installed on both sides of the top outer wall of the base 1, and a clamping mechanism 3 installed in the middle of the top of the base 1. A feeding conveyor belt 6 and a discharging conveyor belt 7 are symmetrically arranged on both sides of the base 1. The same mounting frame 4 is installed on the outer walls of both sides of the base 1, and a robot arm 5 is slidably installed on the inner wall of the mounting frame 4. The clamping mechanism 3 includes a protective box 8 fixedly connected to the base 1, and a clamping component 9 is installed on the bottom inner wall of the protective box 8.

[0016] In this embodiment, the silicon core beam to be drilled is transported to the clamping mechanism 3 by the feeding conveyor belt 6. The robot arm 5 on the mounting frame 4 is activated and simultaneously clamps the silicon core beam to be processed on the feeding conveyor belt 6 and the processed silicon core beam on the clamping mechanism 3. The robot arm 5 moves the silicon core beam to be processed from the feeding conveyor belt 6 to the clamping mechanism 3, and at the same time moves the processed silicon core beam to the unloading conveyor belt 7. The drilling assembly 2 is activated to drill holes in the silicon core beam on the clamping assembly 9. The protective box 8 is used to collect the coolant and chips generated during the drilling process to keep the working environment clean.

[0017] like Figure 3-5The clamping assembly 9 shown includes a clamping seat 14 fixedly connected to the inner wall of the bottom of the protective box 8. The clamping seat 14 has a T-shaped structure. A fixed clamp 19 is fixedly connected to one side of the top of the clamping seat 14, and a movable clamp 20 is slidably connected to the other side of the top of the clamping seat 14. Two symmetrically arranged rectangular openings 23 are opened on one side of the outer wall of the movable clamp 20 and the fixed clamp 19. A cylinder 21 is fixedly connected to the inner wall of the clamping seat 14, and a connecting frame 22 is fixedly connected to the piston rod of the cylinder 21. The connecting frame 22 is fixedly connected to the movable clamp 20. An adjusting box 15 is fixedly connected to the inner wall of the clamping seat 14, and two symmetrically arranged sliding frames 16 are slidably connected to the outer wall of the adjusting box 15. A positioning assembly 18 is installed on the outer wall of each of the two sliding frames 16. A servo motor 17 is fixedly connected to one side of the outer wall of the adjusting box 15. The inner walls of both sides of the regulating box 15 are rotatably connected to the same bidirectional screw 28, and the outer wall of the bidirectional screw 28 is screwed with two symmetrically arranged drive seats 29. The bottom outer wall of the regulating box 15 has two strip-shaped openings 24. The two drive seats 29 pass through the strip-shaped openings 24 and are fixedly connected to the two sliding frames 16. The midpoint of the bidirectional screw 28 is fixedly connected to a worm gear 30. The inner walls of both sides of the regulating box 15 are rotatably connected to a worm gear 31 that meshes with the worm gear 30. The output shaft of the servo motor 17 is fixedly connected to the worm gear 31. The positioning assembly 18 includes an adjusting seat 25 fixedly connected to the sliding frame 16. The adjusting seat 25 has an L-shaped structure. One side of the outer wall of the adjusting seat 25 has an installation opening, and the inner wall of the installation opening is fixedly connected to a fixing rod 26. One end of the fixing rod 26 is fixedly connected to a positioning post 27.

[0018] In this embodiment, the robotic arm 5 places the silicon core beam on the clamping seat 14. The cylinder 21 is started, first pushing the movable clamp 20 through the connecting frame 22, which moves the silicon core beam closer to the fixed clamp 19. At the same time, the servo motor 17 is started, which drives the worm wheel 30 through the worm gear 31 to drive the bidirectional screw 28 to rotate. When the bidirectional screw 28 rotates, it drives the two drive seats 29 to move towards or away from each other. When the two drive seats 29 move towards each other, the sliding frame 16 drives the two adjusting seats 25 to move towards each other. Then, the positioning pins 27 on the two fixed rods 26 are used to position the silicon core beam. After positioning, the cylinder 21 is started, which drives the movable clamp 20 to clamp and fix the silicon core beam, waiting for the hole to be opened. The bidirectional screw 28 has threads with opposite directions of rotation on both sides of the midpoint.

[0019] like Figures 1-2The drilling assembly 2 shown includes a support box 10 fixedly connected to the base 1, and a sliding seat 12 slidably connected to the top outer wall of the support box 10. Two symmetrically arranged center-outlet electric spindles 13 are fixedly connected to the outer wall of the sliding seat 12, and the two center-outlet electric spindles 13 slide through the protective box 8. The same lead screw is rotatably connected to the inner walls of both sides of the support box 10, and the sliding seat 12 is screwed to the outer wall of the lead screw. A servo motor 11 is fixedly connected to one outer wall of the support box 10, and the output shaft of the servo motor 11 is fixedly connected to the lead screw.

[0020] In this embodiment, when drilling, the servo motor 11 is started first to drive the lead screw to rotate. When the lead screw rotates, it directly drives the sliding seat 12 to move. When the sliding seat 12 moves towards the protective box 8, the central water-outlet electric spindle 13 is started, which drives the drill bit to pass through the rectangular opening 23 to drill a hole in the silicon core beam. The simultaneous start of multiple central water-outlet electric spindles 13 improves the efficiency of drilling.
