Description

Technical Field

[0001] The utility model relates to the technical field of ceramic vacuum arc extinguishing chambers, in particular to a guide block for preventing ceramic vacuum arc extinguishing chambers from being misaligned during machining. Background Art

[0002] Ceramic vacuum interrupter, also known as vacuum switch tube, is a new type of core component of high-performance medium and high voltage power switch. During the process of sealing assembly and brazing, a clamp is needed to clamp and fix the material for operation.

[0003] After searching, it was found that the publication number is CN212257227U, and the name is a brazing fixture for the primary sealing assembly of a ceramic vacuum arc chamber. The application proposes a fixture for the processing of ceramic vacuum arc chambers, in which a clamp is used as the main clamping component. However, the length of the clamp is greater than the diameter of the ceramic vacuum arc chamber. Within the length range of the clamp, the ceramic vacuum arc chamber can move left and right, which makes it difficult to accurately position it when clamping, and easily leads to processing misalignment problems. At the same time, it is difficult to stably clamp the cylindrical ceramic vacuum arc chamber by only clamping the two side surfaces of the ceramic vacuum arc chamber. During the processing, the ceramic vacuum arc chamber is also prone to shifting, resulting in misalignment problems. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
