Portable internal thread detection device and detection method thereof

Abstract

The invention provides a portable internal thread detection device and a detection method thereof. The detection device comprises a handle part, a main body measurement part and a control part, the handle part is arranged below the rear portion of the main body measurement part, and the control part is arranged on the side opposite to the handle part; the main body measuring part comprises a driving assembly, a planetary gear train deceleration assembly, a torque sensor and a measuring head replacement assembly, a measuring head is installed on the measuring head replacement assembly, and thedriving assembly drives the measuring head to rotate. According to the portable internal thread detection device provided by the invention, through the L-shaped integral design, handheld online threaddetection is facilitated, and the labor intensity of workers is reduced; go / no-go gauge detection can be carried out on internal threads, the detection efficiency of threaded holes is improved, and the detection time is saved.

Description

technical field [0001] The invention belongs to the technical field of engineering technology measurement, and in particular relates to a portable internal thread detection device and a detection method thereof. Background technique [0002] Products with screw connection form are widely used in aviation, aerospace, shipbuilding, construction, medical treatment and other fields due to their convenient installation and high reliability. Factors that affect thread quality are generally the base material, surface treatment process, and thread comprehensive parameters, among which the detection of thread geometry comprehensive parameters is widely used as an important basis for evaluating the quality of thread products. [0003] At present, the method of detecting thread geometric parameters mainly adopts contact and non-contact measurement methods. Among them, contact measurement mainly includes three-needle method, thread comprehensive scanning measurement method, and working ...
