Abstract

A deep hole straightness detection device disclosed by the present invention comprises a photoelectric auto-collimator, a positioning shaft sleeve, a reflective lens and a mandrel assembly, one end of the photoelectric auto-collimator is inserted into one end of the positioning shaft sleeve, and the other end of the positioning shaft sleeve is inserted into a detected hole. The reflective lens is detachably connected to the side face of one end of the mandrel assembly, and the surface of the reflective lens is perpendicular to the axis of the mandrel assembly. The deep hole straightness detection device has the technical effects that the problem existing in deep hole straightness detection in actual production is solved, the detection precision is improved, the detection difficulty is reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a deep hole straightness detection equipment. Background technique [0002] With the development and progress of the society, the mechanical manufacturing industry has increasing requirements for product quality. In the corresponding standards, the shape and position tolerances of each part in mechanical products are clearly stipulated. Among them, deep hole parts are more and more widely used in the machinery industry, but the straightness detection of deep holes has always been difficult to detect. At present, micrometer collimation telescopes are mainly used for measurement in actual production. [0003] However, the above detection method has the following disadvantages: the accuracy of the instrument itself can only reach 0.05mm, which does not include the positioning error of the differentiation plate in the hole and the error caused by the increase of the measu...
