Boring cutter for processing inner bore of nozzle of circuit breaker

一种加工断路器喷口内孔的镗刀

Abstract

本实用新型提供了一种加工断路器喷口内孔的镗刀,包括刀体、刀杆,所述刀体连接在所述刀杆一端,其中,所述刀体上仞口与水平线的夹角α成95°,由于刀体1上仞面与水平线的夹角α为95°,可根据喷口的外形,对喷口的内孔进行精确加工,对于喷口细微的形状变化,都可以完成,因此,本实用新型加工喷口内孔精确度高,且结构简单。
The utility model provides a boring cutter for processing an inner pore of a nozzle of a circuit breaker, which comprises a cutter body and a cutter rod, wherein the cutter body is connected with one end of the cutter rod, and an included angle alpha between the cutting edge on the cutter body and the horizontal line is 95 degrees. Because the included angle alpha between the cutting edge on the cutter body and the horizontal line is 95 degrees, the inner pore of the nozzle can be precisely processed according to the size of the nozzle, and the fine shape change on the nozzle can be completed. Thereby, the utility model ensures the high precision of the inner pore of the nozzle and has simple structure.
