[0002] The automobile part thread perpendicularity detection device is a key equipment for ensuring the precision of automobile part thread connection. Its core detection method is laser measurement. Before the automobile part is assembled, the device detects the thread hole and stud by means of laser measurement. Specifically, the laser profile measuring instrument is used to emit a laser beam, which is projected onto the inner wall of the thread hole. The reflected laser line image is received, and data is calculated according to the laser triangulation principle to obtain the perpendicularity of the thread hole. For the stud, point cloud data is first obtained by laser measurement, and then the vector is fitted by algorithm processing to judge the perpendicularity of the stud. With the non-contact characteristics and high precision advantage of laser measurement, the effectiveness of the thread hole and stud connection can be accurately determined, and the reliability and assembly precision of the automobile part thread connection can be greatly improved.
