Description

Flange bolt test fixture Technical Field The utility model relates to the technical field of bolt testing, in particular to a flange bolt testing tool. Background The flange bolt is an integrated bolt consisting of a hexagon head, a flange plate (a gasket below the hexagon and a hexagon are fixed integrally) and a screw rod (a cylinder with external threads), and is matched with a nut for fastening two parts of two through holes. The flange bolt tip is installed with the form of hexagon more and is connected, need use the indent hexagonal pole cover to establish in the outside of hexagon and then detect work when detecting the bolt, when detecting the flange bolt, need change assorted indent hexagonal pole to the hexagon of different width bolts, detect in the outside of hexagon with corresponding indent hexagonal pole cover later, so reduced the work efficiency who detects work, therefore put forward a flange bolt test fixture. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a flange bolt testing tool for solving the problems in the background art. In order to achieve the above purpose, the flange bolt testing tool comprises a mounting frame and a connecting disc, wherein the outer surface of the front side of the connecting disc is fixedly connected with four connecting frames in a circumferential array, the other end of the connecting frame is fixedly connected with a fixing plate, the outer surface of the connecting disc is fixedly provided with a cylinder, the output end of the cylinder is fixedly connected with a fixing cylinder, a fixing groove is formed in the fixing cylinder, a hexagonal groove is formed in the outer surface of the fixing plate, first springs are fixedly connected to the six inner walls of the hexagonal groove, the other end of each first spring is fixedly connected with a connecting plate, the rear side of the connecting plate is fixedly connected with an extrusion plate, and the other side of the connecting plate is provided with a clamping plate.
