Abstract

The invention relates to the technical field of photoelectric detection, and especially relates to a device and method for measuring the geometric parameters of a long and thin hole. The device comprises a positioning mechanism, a traveling mechanism and a measurement mechanism. The positioning mechanism is used for the automatic centering of a to-be-detected workpiece. The measurement mechanism comprises an automatic centering head, a toughness measuring rod, a laser, a pneumatic sensor, and a CCD processor. An optical fiber of the laser passes through an internal channel of the toughness measuring rod to be connected with a laser sight, and the laser sight is in signal connection with the CCD processor. An air source of the pneumatic sensor is communicated with a pneumatic centering measuring head through an air inlet of the toughness measuring rod. The traveling mechanism is used for carrying the toughness measuring rod to move, and enabling an automatic centering measuring head atthe second end to move to the inlet of the long and thin hole of the to-be-detected workpiece. The device can achieve the detection of the linearity of the axis and roundness of the long and thin holeconveniently, and is not limited by the rigidity and length of the measuring rod.

Description

technical field [0001] The present invention relates to the technical field of photoelectric detection, in particular to a device and method for measuring geometric parameters of elongated holes, and in particular to a device and method for measuring the straightness and roundness of the axes of elongated holes. Background technique [0002] The straightness and roundness detection of the slender hole axis is an important part in the processing of slender hole parts, an important means of quality control and management of slender hole parts, and a technical guarantee for implementing quality standards. The measurement of the straightness and roundness of the axis of the slender hole is of great significance to the rational use of industrial production and products, especially for the aerospace and weapon industries, the straightness of the axis and the roundness of the inner hole are very important indicators, which directly affect Performance and weapon accuracy of slender ...
