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 digital display laser inner diameter measuring instrument. The digital display laser inner diameter measuring instrument comprises a handle, a main control box, a connecting rod, a rotating rod and a spherical measuring head. According to the laser inner diameter measuring instrument, non-contact laser measurement is adopted; the spherical measuring head is rotated so as to carry out continuous measurement; three laser distance measuring instruments measure the inner wall of a workpiece, so that three-point distance groups can be obtained; and measured sectional plane inner diameter values corresponding to the three-point distance groups are calculated, a minimum value in the inner diameter values is obtained through comparison, the minimum value is the radial plane inner diameter value of the workpiece. The digital display laser inner diameter measuring instrument has the advantages of high accuracy and easy operation process, and can assist in effectively eliminating human-made errors brought by traditional contact type measurement. A fast and accurate measurement tool and method can be provided for the deep hole measurement of the workpiece.

Description

technical field [0001] The invention relates to the field of inner diameter measurement, in particular to a digital display 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. ...
