Description

TECHNICAL FIELD

[0001] The present application relates to the field of alumina ceramic ring clamping mechanical claws, in particular to an alumina ceramic ring clamping mechanical claw. BACKGROUND

[0002] The alumina ceramic ring is a ceramic sealing ring mainly composed of alumina. It is also called a ceramic sealing ring, a ceramic sealing gasket, etc. The ceramic sealing ring has excellent sealing and lubricating performance and can withstand high temperatures above 1000 DEG C. It has small deformation at high and low temperatures; the production process of the ceramic sealing ring is formed by molding and sintering, and the production cost is low, and the qualified rate of finished products is high. The alumina ceramic ring has low dielectric constant, small dielectric loss, high insulation strength, high volume resistivity, good bending strength, high stability, high pressure resistance, and good cold and hot impact resistance. It is widely used in temperature controllers, insulation parts of various small household appliances, various thermal equipment, electric heating equipment, iron structure buildings, shipbuilding, etc.

[0003] The alumina ceramic ring has the advantages of high hardness, excellent wear resistance, corrosion resistance, high temperature resistance, good self-lubricating property, and is not easy to scale. The alumina ceramic fitting has high hardness, high strength, low expansion coefficient, and is insulating, wear-resistant and corrosion-resistant, and is widely used in mechanical manufacturing, aerospace, precision instruments, petrochemical industry, new light source, textile machinery, electrical appliances, refrigeration equipment, electric heating instruments, instruments, chemical industry, communication, communication and other industries. The alumina ceramic ring has the following disadvantages: the elastic modulus is relatively large, the hardness is high, the brittleness is large, and the crack sensitivity is strong, so the main difficulty in machining the alumina ceramic ring is the hardness and brittleness. The microstructure of the alumina ceramic is equiaxed grain, which is a polycrystalline structure composed of ionic bonds or covalent bonds, so the fracture toughness is low. Under the action of external load, stress will cause fine cracks on the surface of the ceramic, and the cracks will rapidly expand to cause brittle fracture, so the alumina ceramic ring often appears the phenomenon of collapse during machining and cutting, that is, small cracks appear on the surface of the ceramic.

[0004] Due to the brittleness of the alumina ceramic ring, the existing mechanical claws usually adopt external clamping to clamp the alumina film during clamping and transportation, and then when the clamping force acts on the ring-shaped alumina ceramic ring, it is easy to cause deformation of the alumina ceramic ring, and then cause the alumina ceramic ring to crack under stress, so a alumina ceramic ring clamping mechanical claw solving the above problems is needed.
