Problems solved by technology

This method has low measurement efficiency, few measurement parameters, poor measurement repeatability, low stability, and is easily affected by the environment and operators
Non-contact measurements such as the Doppler effect method, laser interferometer, and laser lever method have high accuracy, but due to the on-site environment, they are not suitable for on-site measurement of large workpieces
Moreover, the above methods are not suitable for depth measurement.

Abstract

The invention provides a laser inner diameter measuring instrument which comprises a handle, a main rod, a rotary fulcrum rod, a measuring ring and spherical hinges. According to the laser inner diameter measuring instrument, non-contact type laser measurement is adopted, the measuring ring is turned for continuous measurement, three laser heads measure the inner wall of a workpiece to obtain three-point distance sets, measured section plane inner diameter values corresponding to all the three-point distance sets are obtained, the minimum values in the obtained inner diameters are compared, and the radial plane inner diameter value of the workpiece is obtained. The measuring instrument is high in measurement precision, the operation process is easy and convenient, personal errors caused by traditional contact measurement are effectively eliminated, and a fast and precise measuring tool and method are provided for workpiece deep hole measurement.

Description

technical field [0001] The invention relates to the field of inner diameter measurement, in particular to a laser inner diameter measuring instrument. Background technique [0002] The traditional inner diameter detection uses a go gauge and a stop gauge, which cannot quantify the measured value; the vernier caliper or inner micrometer used for inner diameter measurement is also limited to the measurement of the inner diameter of the orifice; for the contact measurement of the inner diameter dial indicator or dial gauge, it is necessary to shake the axis first Measure to find the axial minimum value, and then shake in the circumferential direction to find the radial maximum value. The measurement process is cumbersome, and the measured value is not unique due to personal experience; on the other hand, these are contact measurements, which are easy to correct High-precision machining of the surface of the workpiece causes scratches and damages the workpiece. [0003] For a l...
