Abstract
The invention discloses a device for measuring the diameter size of an orifice chamfering. The device comprises a measuring sleeve and a measuring body. The measuring body is composed of a guiding cylindrical section, a matching cylindrical section, and a measuring conical section between the guiding cylindrical section and the matching cylindrical section, wherein the guiding cylindrical section, the matching cylindrical section and the measuring conical section are coaxial and match a cylindrical hole of which the orifice chamfering diameter is to be measured. The diameter of the matching cylindrical section is greater than the maximum design diameter of the orifice chamfering. The conical angle of the measuring conical section is the same with that of the orifice chamfering. The upper end face of the measuring body is perpendicular to the axis of the measuring body. The measuring sleeve is provided with a guiding cylindrical hole matching the matching cylindrical section of the measuring body. The axis of the guiding cylindrical hole is perpendicular to the upper and lower end planes of the measuring sleeve. The upper end face is a step end plane divided into two parts, and the step height is a value converted from the diameter tolerance of the orifice chamfering. The length of the measuring sleeve matches that of the guiding cylindrical section of the measuring body. By using the device to measure the diameter size of an orifice chamfering, measurement operation is simplified, and the accuracy and efficiency of measurement are improved.
