Embodiment 2

[0024] Figures 1-4This invention illustrates a quartz crucible inner wall grinding positioning device according to an embodiment of the present invention. It includes: a bottom support plate 1; a middle support plate 2 is bolted to the top of the bottom support plate 1; a hollow disc 3 is bolted to the top of the middle support plate 2; four limiting support members 4 are welded to the surface of the hollow disc 3; support rods 5 are rotatably connected to the surfaces of the four limiting support members 4; a threaded rod 6 is rotatably connected to the inner cavity of the hollow disc 3; a four-headed sliding member 7 is threadedly connected to the surface of the threaded rod 6; a connecting rod 8 is rotatably connected between the four-headed sliding member 7 and the support rod 5; and a connecting rod 8 is rotatably connected to the top of the support rod 5. The top of the triangular clamping head 9 and the middle support plate 2 are fixedly connected to the top support plate 12 by bolts. The surface of the top support plate 12 has four limiting grooves. Four reinforcing rods 14 are welded between the top of the bottom support plate 1 and the bottom of the middle support plate 2. The bottom of the bottom support plate 1 is fixedly connected to the bottom of the rubber trapezoidal expansion plate 15. With the setting of the reinforcing rods 14, when the bottom support plate 1 supports the middle support plate 2, the bottom of the middle support plate 2 and the top of the bottom support plate 1 can get auxiliary support force, which can make the middle support plate 2 more stable when supporting the triangular clamping head 9.

[0025] Working Principle: When using this invention, the user places the quartz crucible on top of the top support plate 12, then starts the motor 11 to drive the threaded rod 6 to rotate. This causes the threaded rod 6 to drive the four sliding parts 7 to slide downwards. Simultaneously, the four sliding parts 7 drive the connecting rod 8 to deflect, which in turn causes the connecting rod 8 to pull the support rod 5 and the triangular clamping head 9 to slide. At this time, the auxiliary support of the driven support rod 10 can keep the triangular clamping head 9 sliding stably. Then, the four triangular clamping heads 9 slide in opposite directions, thereby clamping and fixing the crucible body. This ensures that the crucible body is fixed and limited, ensuring that the crucible body remains stable during grinding. This allows the operator to accurately control the position and force of the grinding tool, thereby improving the grinding accuracy.

[0026] In summary, this quartz crucible inner wall grinding positioning device uses a starting motor 11 to drive the threaded rod 6 to rotate. This, in turn, causes the four-headed sliding member 7 and connecting rod 8 to pull the support rod 5 and the triangular clamping head 9 to slide, thereby clamping and fixing the crucible body with the triangular clamping head 9. This achieves the goal of fixing and limiting the crucible body, ensuring stability during grinding. This allows the operator to precisely control the position and force of the grinding tools, thus improving grinding accuracy.
