[0003] In the related art, for products with arc-shaped surfaces, the grinding uniformity and grinding effect of the grinding equipment are poor. Summary of the invention

[0004] Based on this, it is necessary to provide a grinding device to address the problems of poor grinding uniformity and grinding effect in the grinding equipment in the related art.

[0005] An embodiment of the utility model provides a grinding device, including a supporting mechanism, a grinding mechanism and a position adjustment mechanism; the supporting mechanism includes a first driving member and a roller assembly, the first driving member is connected to the roller assembly, the roller assembly has a grinding position for supporting the product to be ground, and the first driving member is used to drive the roller assembly to rotate; the grinding mechanism has a grinding member facing the grinding position and rotatable relative to the product to be ground; the grinding mechanism is connected to the position adjustment mechanism, and the position adjustment mechanism is used to adjust the relative position between the grinding mechanism and the supporting mechanism.

[0006] In one embodiment, the roller assembly includes two rollers, the axes of the two rollers are parallel and spaced apart, and the grinding position is formed between the two rollers.

[0007] Specifically, the product to be polished is supported by two rollers, that is, the product to be polished is equivalent to being mounted between the two rollers, and the outer surface of the product to be polished is in contact with the outer surface of the roller. Accordingly, the spacing between the two rollers is smaller than the diameter of the product to be polished, so that the product to be polished can fully contact the two rollers and will not fall from between the two rollers. When the rollers rotate, the rollers drive the product to be polished to rotate synchronously through friction.

[0008] In one embodiment, the first driving member is connected to at least one of the two rollers.

[0009] Specifically, the first driving member can be connected to both rollers at the same time, or can be connected to one of the rollers; when the first driving member is connected to both rollers at the same time, both rollers act as active rollers to drive the product to be polished to rotate; when the first driving member is connected to one of the rollers, the roller connected to the first driving member acts as an active roller to drive the product to be polished to rotate, and the other roller acts as a driven roller to rotate along with the product to be polished.

[0010] In one embodiment, the grinding mechanism further includes a second driving member; the second driving member is connected to the grinding member.

[0011] Specifically, the second driving member drives the polishing member to rotate. According to the actual product to be polished, a transmission shaft can be additionally provided. The second driving member is connected to the polishing member through the transmission shaft so that the polishing member can fully extend into the interior of the product to be polished, thereby meeting the polishing requirements of the product to be polished with a deeper polishing area.

For example, when the crucible rotates, the polishing piece polishes the inner surface of the crucible.

[0015] In one embodiment, the position adjustment mechanism includes a first guide structure, a second guide structure and a base; the first guide structure is extended along a first direction, and the second guide structure is extended along a second direction; the base is movably provided on the first guide structure along the first direction, the second guide structure is provided on the base, and the grinding mechanism is movably provided on the second guide structure along the second direction; wherein the first direction is perpendicular to the second direction.

[0016] The first direction is the direction of the X-axis in the horizontal plane, and the second direction is the vertical direction, that is, the direction of the Z-axis; by moving the base on the first guide structure, the grinding mechanism is moved toward the side close to the product to be grinded or the side away from the product to be grinded, and by moving the grinding mechanism on the second guide structure, the relative height between the grinding piece and the product to be grinded is adjusted to adjust the grinding piece to a suitable grinding position, and multiple positions on the product to be grinded can be ground.

[0017] Wherein, both the first guide structure and the second guide structure can be guide rails.

[0018] In one of the embodiments, the grinding device further includes a dust collection mechanism; the dust collection mechanism has a receiving cavity for receiving the product to be grinded at the grinding position, and a dust suction port facing the grinding position and connected to the receiving cavity.

[0019] Specifically, during the grinding process, the product to be grinded is located in the accommodating chamber to gather the dust into the accommodating chamber, thereby reducing the leakage of dust. Finally, the dust generated during the grinding process is sucked and collected through the dust suction port, thereby protecting the environment. In addition, the dust of some special materials can be recycled, thereby improving the utilization rate of the materials.

[0020] In one embodiment, the dust collection mechanism has a first position and a second position. In the first position, the grinding position is located inside the accommodating chamber; in the second position, the grinding position is located outside the accommodating chamber.

[0021] Specifically, during the process of placing the product to be polished on the polishing position, the dust collecting mechanism is adjusted to the second position to expose the polishing position, so that the operator can place the product to be polished on the polishing position; then the dust collecting mechanism is adjusted to the first position so that the dust collecting mechanism can cover the product to be polished, thereby gathering the dust generated during the polishing process in the containing chamber to achieve dust isolation; at the same time, since the polishing process is located in the containing chamber, it can also reduce the flying of foreign matter, thereby improving the safety of production.

[0022] In one of the embodiments, the grinding device further includes a third guide structure; the dust collecting mechanism is movably disposed on the third guide structure to switch between the first position and the second position.

[0023] Specifically, by providing the third guide structure, a stable guiding effect is provided for the position switching of the dust collecting mechanism.

[0024] The third guide structure may be a guide rail, and the extension direction of the guide rail is parallel to the rotation axis of the roller assembly.

[0025] In one embodiment, the dust collection mechanism includes a cover body and a connecting plate; the connecting plate is located in the cover body, the inner surface of the cover body and the surface of the connecting plate define the accommodating cavity, the cover body is movably disposed on the third guide structure, and the dust suction port is located on the connecting plate.

[0026] Specifically, the relative position between the connecting plate and the grinding position remains unchanged, and the switching of the position of the dust collection mechanism is actually the switching of the position of the cover body. The cover body is moved toward the side close to the grinding position, so that the product to be grinded is covered in the cover body, and the cover body is moved toward the side away from the grinding position to facilitate the placement and removal of the product to be grinded.

[0027] The above-mentioned grinding device drives the product to be grinded to rotate through the supporting mechanism, and the grinding piece rotates relative to the product to be grinded to grind the product to be grinded. At the same time, the position of the grinding mechanism is adjusted by the position adjustment mechanism, so that multiple positions on the product to be grinded can be evenly grinded. In actual use, the product to be grinded is placed on the grinding position, and the relative position between the grinding mechanism and the product to be grinded is adjusted by the position adjustment mechanism, so that the grinding piece is moved to the position of the product to be grinded that needs to be polished, and the grinding mechanism and the first driving member are turned on, so that the grinding piece and the product to be polished both start Rotation, the rotation of the two improves the grinding efficiency of the product to be polished. Compared with the grinding method in the related art in which one is fixed and the other is rotated, it reduces the excessive grinding of a certain part on the product to be polished by the grinding piece, and improves the uniformity of grinding. After the grinding of one part on the product to be polished is completed, the position of the grinding piece is adjusted by the position adjustment mechanism, so that another part on the product to be polished is polished, thereby achieving uniform grinding of multiple positions.
