AI Technical Summary
A large amount of dust is generated during the polishing process of graphite crucibles, which leads to long-term work of the vacuum fan, resulting in high power consumption, which is neither economical nor environmentally friendly.
A graphite crucible polishing device is designed. By placing a vacuum cylinder and a fan shell on the outer sleeve of the polishing wheel, and a impeller is placed on the connecting shaft in the fan shell. When the polishing wheel is driven by the motor, the impeller rotates simultaneously at high speed to generate a strong suction force, sucking dust into the fan shell and discharged into the dust collecting device through the hose.
Through this device, power consumption is greatly reduced, and a more economical and environmentally friendly polishing process is achieved.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
[0016] like Figure 1-Figure 3As shown, a graphite crucible polishing device includes a machining center 2, which is a three-axis machining center. The machining center 2 includes an X-axis slide, a Y-axis slide, and a Z-axis slide that are connected to each other. A crucible fixture 120 is installed on the moving end of the X-axis slide of the machining center 2. The crucible fixture 120 is a three-jaw chuck.
