Ceramic knife edge sharpening machine

Abstract

The invention discloses a ceramic knife edge sharpening machine. The machine comprises a grinding wheel and a bearing arm, and the axis of the grinding wheel is perpendicular to a YZ plane; a tool rest used for installing a tool is arranged at the front end of the bearing arm, and the bearing arm is driven by a first driving mechanism to move away from or close to the grinding wheel in the X-axisdirection, so that when the front end of the bearing arm penetrates through the grinding wheel, the grinding wheel conducts grinding operation on a cutting edge of the tool on the tool rest; and the bottom of the bearing arm is provided with at least one profiling groove in the same shape as the cutting edge of the tool, the profiling groove is connected to an eccentric shaft in a sliding manner,and the eccentric shaft is driven by a second driving mechanism to rotate and drive the bearing arm to move away from or close to the grinding wheel in the Z-axis direction. The machine is simple in structure, high in machining precision and convenient to use.

Description

Technical field[0001]The invention relates to the field of ceramic knife processing equipment, in particular to a ceramic knife sharp edge machine.Background technique[0002]Ceramic cutters are made of high-purity ultra-fine zirconia as raw materials, and are manufactured through various processes such as spray granulation, isostatic pressing, and precision machining. It has the characteristics of high hardness, strong corrosion resistance, good chemical stability, and high wear resistance. , The appearance is beautiful and exquisite, and the cutting edge is extremely sharp. It is a real knife that will never wear and never corrode.[0003]At present, most of the cutting operations of ceramic knives use manual or machine processing methods, and the efficiency and productivity of manual processing are low; although the automatic processing of machines can improve the production efficiency; the shape of the ceramic knives to be processed is subtle The difference is that the depth of the ...

Problems solved by technology

[0003] At present, most of the sharpening operations of ceramic knives are done manually or by machine, and the efficiency and production capacity of manual processing are low; although the automatic machining of machines can improve production efficiency; but there are subtle differences in the shape of the ceramic knives to be processed. The difference is that the depth of the cutting edge and the feeding process of the knife are fixed in the current sharpening machine, which leads to uneven grinding effect of the ceramic knife edge and inconsistent sharpness of the finished product.

[0004] Chinese document CN1895845A discloses a ceramic knife sharpening device, which installs the knife on the tooling grinding disc, and then uses a sharpening wheel that can move in the XY plane to perform sharpening operations on the tool on the rotating tooling grinding disc; the application The above-mentioned defects exist in the scheme, that is, the movable space of the grinding wheel or the tool is limited. When facing each tool with a small difference in shape, there are differences in the cutting results, resulting in that the cutting results of no tools are not good. same, affect the quality of the product
