| description | The invention relates to a special vehicle hydraulic system hollow bolt fastening device and method. The device comprises a sleeve, a probe coil, a transmission cable, a stress application rod and a wrench. Wherein the cylindrical part at the lower end of the sleeve is matched with the hollow bolt in specification and can be conveniently sleeved on the head of the hollow bolt for screwing, the distance between the sleeve and the base body is always kept unchanged, and meanwhile a threaded through hole is machined in the top of the sleeve; the probe coil is integrated by an eddy current sensor and a measuring head, and the head of the probe coil is processed into a screw structure and is screwed into a threaded through hole in the top of the sleeve to measure the descending distance of the top of the hollow bolt. The method comprises the following steps: firstly, selecting a proper compression amount required by copper gasket sealing; the fastening device is used for detecting the change of the compression amo |
