Regarding other technical contents, features and effects of this creation, it will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

Regarding the bolt height detection method of this creation, the steps of the method include: installation configuration, a body with a perforation is installed in a pneumatic device, and a detection element for detection is installed in the perforation, and the body is erected on A processing lock bolt and a nut on a conveying path; conveying positioning, after the nut is processed and locked on the bolt, following the conveying path to move below the perforation; performing a test, which is controlled by the pneumatic device The main body is lowered, the perforation is inserted into the bolt, and the detection element is retracted by the abutment of the bolt; the height is calculated, and the amount of the retracted distance of the detection element is obtained through a computing device, and the measured The protruding length of the bolt after locking the nut to determine whether the nut has reached the correct locking position.

The above bolt height detection method can be performed in conjunction with a bolt height detection device. For the bolt height detection device, please refer to Figs. 1 to 3, which are three-dimensional and cross-sectional schematic diagrams of this creation. As shown in the figure, at least The control unit 1 includes a control unit 1, a detection unit 2 and an outer frame body 3. The control unit 1 has a lifting element 11 which is connected to an air pressure. The control element 12 and a carrier 13 are provided with at least one perforation 14, and the outer diameter of each of the perforations 14 is slightly larger than the outer diameter of a bolt 4 to be detected; wherein the detection unit 2 has a A detection element 21 installed in each of the perforations 14 is connected to a processing element 22, and the processing element 22 is connected to a computing element 23.
