Description

Technical Field

[0001] The utility model relates to the technical field of zirconium oxide processing equipment, in particular to a top-to-top material clamping mechanism of a zirconium oxide block cutting device. Background Art

[0002] Zirconia can be used to make porcelain teeth or all-ceramic teeth, and can also be used to make zirconia beads. Zirconia beads can be used as polishing materials to polish gold, silver or other metal objects. Zirconia can also be mixed with other materials to make artificial gemstones. Its specific application scenarios are relatively wide.

[0003] At present, in the process of manufacturing porcelain teeth or all-ceramic teeth, it is first necessary to press the zirconium oxide into a block to form a disc-shaped zirconium oxide block, and then put the zirconium oxide block into a cutting device to cut out a specific shape, and then take it out and perform other processes such as sintering and molding to complete the production of porcelain teeth or all-ceramic teeth. Before cutting the disc-shaped zirconium oxide block, a special clamp is required to fix it. At present, the zirconium oxide block is usually placed in the clamp manually, and the fastening screws are installed with a screwdriver so that the zirconium oxide block is clamped and fixed. After the cutting action is completed, the clamp is manually loosened with a screwdriver to take out the semi-finished product to be sintered. Therefore, the entire cutting action requires manual waiting. At the same time, due to the presence of a large amount of splashes during the cutting process of the zirconium oxide block, the current cutting device usually places the cutting mechanism in the box, which makes the installation and disassembly of the zirconium oxide block more inconvenient.

[0004] In the above background, the inventors have designed a top-to-top clamping mechanism for a zirconia block cutting device to solve one or more of the above problems, and thus proposed the present application. Utility Model Content
