[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. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A graphite boat grinding device includes a frame 1, a grinding head 8, and an industrial vacuum cleaner 17, model DL750-30. The top of the frame 1 is provided with a lifting assembly for moving the grinding head 8 up and down. The lifting assembly includes multiple round rods 2, which are all bolted to the top of the frame 1 at the four corners. The top of the multiple round rods 2 is bolted to a top plate 4. A self-locking hydraulic cylinder 5 is bolted to the center of the top of the top plate 4. A first slide 3 is slidably connected to the outside of the multiple round rods 2, and the telescopic part of the self-locking hydraulic cylinder 5 passes through the top plate 4 and is fixed to the first slide 3. A second motor is bolted to one side of the first slide 3. When the self-locking hydraulic cylinder 5 is activated, its telescopic part pushes the first slide 3 down along the round rods 2 to the required height of the grinding head 8. The grinding depth is controlled by the height of the grinding head 8.

[0024] In this utility model, the bottom of the first slide 3 is provided with a translation component for horizontally moving the grinding head 8. The translation component includes a second lead screw 12, which is rotatably connected to the inner walls of both sides of the first slide 3 via bearings. The output shaft of the second motor passes through the first slide 3 and is fixed to the second lead screw 12 via a coupling. The outer side of the second lead screw 12 is threadedly connected to the second slide 10. The first slide 3 is provided with a guide component for horizontally moving the second slide 10. The guide component consists of two limiting rods 11, both of which are fixed to the inner walls of both sides of the first slide 3 by bolts. The limiting rods 11 are slidably connected to the second slide 10, allowing the second slide 10 to move horizontally and stably along the limiting rods 11. The bottom of the second slide 10 is provided with a groove 7, and the first lead screw 6 is rotatably connected to the groove 7 via bearings. One side of the second slide 10 is fixed with a first motor by bolts. The output shaft of the motor passes through the second slide 10 and is fixed to the first lead screw 6 via bearings. The outer side of the first lead screw 6 is threaded with a slide block 9 that moves along the slide groove 7. The bottom of the slide block 9 is fixed with a drive motor that rotates the grinding head 8 by bolts. By starting the second motor, the second lead screw 12 is rotated. The forward and reverse rotation of the second lead screw 12 drives the second slide 10 to move vertically and horizontally along the axis of the limit rod 11. At the same time, the first motor can be started to drive the first lead screw 6. The forward and reverse rotation of the first lead screw 6 drives the slide block 9 to move laterally along the slide groove 7. While moving, the drive motor is started to rotate the grinding head 8, so that the grinding head 8 moves horizontally. This allows the grinding head 8 to move horizontally, thereby changing the position of the grinding head 8 and grinding different positions on the upper surface of the graphite boat. This not only significantly improves the grinding efficiency but also ensures the consistency of grinding quality and uniformity.

[0025] In particular, the top of the frame 1 is provided with a through groove, in which a dust collection box 15 is provided and fixed to the frame 1. The top of the dust collection box 15 is fixed with a strainer plate 13 by bolts. At the center of the top of the strainer plate 13, a placement plate 18 is fixed with bolts. The top of the placement plate 18 is fixed with two L-shaped frames 20 by bolts. Both sides of the two L-shaped frames 20 are threaded with threaded rods 19. One end of each threaded rod 19 is rotatably connected to a clamping block 22. One side of each clamping block 22 is fixed with two guide rods 21 that pass through the L-shaped frame 20 by bolts. First, the graphite boat blank is placed on the placement plate 18. Then, the multiple threaded rods 19 on the L-shaped frame 20 are rotated, so that the clamping block 22 moves along the axial direction of the L-guide rod 21, so that the multiple clamping blocks 22 clamp the graphite boat blank. This allows for precise clamping and positioning of graphite boat blanks of different sizes. This design simplifies the operation process, reduces production costs, and can efficiently achieve precise clamping and positioning of graphite boat blanks of different sizes.

[0026] In particular, the bottom of the dust collection box 15 is fixed with a corrugated pipe 16 by bolts, and the corrugated pipe 16 is fixed with the industrial vacuum cleaner 17. After the grinding starts, the industrial vacuum cleaner 17 is started, and the grinding debris will fall onto the sluice plate 13. The suction of the industrial vacuum cleaner 17 is transmitted to the holes of the dust collection box 15 and the sluice plate 13 through the corrugated pipe 16. The dust will be drawn into the industrial vacuum cleaner 17 with the suction. The two L-shaped frames 20 are located at the opposite corners of the placement plate 18, which facilitates the multi-directional clamping of the graphite boat blank. Rubber pads are glued to the side of the multiple clamping blocks 22 adjacent to the graphite boat, and the rubber pads are the same size as the clamping blocks 22, which protects the graphite boat blank when clamping.

[0027] Working principle: First, the graphite boat blank is placed on the placement plate 18. Multiple threaded rods 19 on the rotating L-shaped frame 20 cause the clamping blocks 22 to move axially along the L-guide rod 21, clamping the graphite boat blank. This allows for precise clamping and positioning of graphite boat blanks of different sizes. This design simplifies the operation process, reduces production costs, and efficiently achieves precise clamping and positioning of graphite boat blanks of different sizes. At this time, the self-locking hydraulic cylinder 5 is activated, causing its telescopic part to push the first slide 3 down along the round rod 2 to the required height of the grinding head 8. The grinding depth is controlled by the height of the grinding head 8. The second motor is activated to electrically rotate the second lead screw 12. The forward and reverse rotation of 12 drives the second slide 10 to move vertically and horizontally along the axis of the limiting rod 11. At the same time, the first motor can be started to drive the first lead screw 6. The forward and reverse rotation of the first lead screw 6 drives the slide 9 to move laterally along the slide groove 7. While moving, the drive motor is started to make the grinding head 8 rotate, so that the grinding head 8 moves horizontally. This design not only significantly improves the grinding efficiency, but also ensures the consistency of grinding quality and uniformity. After the grinding starts, the industrial vacuum cleaner 17 is started. The grinding debris will fall onto the sluice plate 13. The suction of the industrial vacuum cleaner 17 is transmitted through the corrugated pipe 16 to the dust collection box 15 and the sluice plate 13. The dust will be drawn into the industrial vacuum cleaner 17 with the suction.

[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
