The invention discloses a calibration device and a calibration method of a sliding micrometer and relates to the technical field of detection instruments. The calibration device comprises a shell, a measuring tube, two measuring rings, a humidity and temperature gauge, a guide structure, a fixture and a transmission component, wherein the measuring tube is arranged in the shell and comprises a first end opening and a second end opening, the first end opening and the second end opening are both open, the edge of the first end opening is connected with the shell, the shell is provided with a first open hole corresponding to the first end opening in position, and a probe of the sliding micrometer extends into the measuring tube from the first open hole and the first end opening; the two measuring rings are both arranged on the measuring tube, and a distance value between the two measuring rings is equal to standard length of the probe; and the humidity and temperature gauge is arranged onthe shell, the fixture is used for clamping guide rods, the fixture is arranged on the guide structure and is connected with the transmission component, and the transmission component can drive the fixture and the guide rods to move along the guide structure. Through the arrangement, whether the probe is suitable for observation or not can be calibrated accurately and rapidly, and a measurement error is avoided.
Description
technical field [0001] The invention relates to the technical field of detection instruments in hydraulic safety observation engineering, and more specifically relates to a verification device and a verification method of a sliding micrometer. Background technique [0002] In engineering, the sliding micrometer is a device used to monitor the vertical or lateral deformation of underground caverns, and its measurement system has the characteristics of high precision and high resolution. Such a high-precision monitoring instrument needs to be used with great care, and the monitoring equipment should not be placed in a humid, dusty and vibration environment. At the same time, when the sliding micrometer is used on the project site, it is required that the monitoring equipment must be adapted to the temperature, humidity and other environments of the site before measurement can be performed. [0003] As we all know, the environment of underground caverns in water conservancy an...
