A kind of gas sensor head anti-burst chamfer device

Abstract

The utility model discloses a kind of chamfering devices of gas sensor head anti-burst, including chamfering grinding wheel, chamfering grinding wheel inside has the chamfering hole of through chamfering grinding wheel one end face, the chamfering hole includes the conical bore section and the circular bore section of coaxially arranged in turn and intercommunication;The conical bore section forms sample inlet by the end of through chamfering grinding wheel, and the inner diameter of conical bore section gradually decreases along the end of through chamfering grinding wheel towards inside;Chamfering grinding wheel can rotate around the axis of chamfering hole, utilize the inner wall of chamfering hole to the sensor chip of chamfering that enter chamfering hole from sample inlet is carried out.The utility model is set to have the bore structure of grinding wheel, utilize the inner wall of bore and chamfer, can chamfer 4 edges at a time, improve chamfering efficiency, can also avoid new aperture defect when chamfering, simultaneously through the conical hole and circular hole of in turn intercommunication setting, can take into account the whole chamfering or gradual chamfering of gas sensor edge.
