[0002] With the continuous development of modern industrial technology, alumina ceramics have been widely used in many fields such as aerospace, electronic communications, and medical equipment due to their high hardness, high wear resistance, high corrosion resistance, good insulation and thermal conductivity. However, the hard and brittle characteristics of alumina ceramic materials make it easy to crack, collapse and other problems during processing. Especially when processing thin-walled alumina ceramic structural parts, in order to avoid cracks and other situations, corresponding special types of clamps are usually used for clamping operations.
[0003] However, when most of the clamps for thin-walled alumina ceramic production are in use, the orientation of the clamping head is constant, and they can generally only be set horizontally or vertically. Although the clamping operation can be completed, it can only be clamped along the corresponding plane. There is a defect that the angle cannot be adjusted and the orientation cannot be changed for clamping, which affects the clamping and use effects and brings inconvenience to the user. In view of this, we propose a clamp for thin-walled alumina ceramic production. Utility Model Content
