Description
Technical Field
The utility model relates to a narrow space interference fit high lock bolt mounting tool, belongs to the technical field of aviation structure assembly, and is used for mounting narrow space interference fit bolts.
Background
The structure of a certain aircraft body mainly adopts a riveting and screwing connection mode. And nearly 90% of the screw joints are connected by adopting interference fit high-lock bolts. The interference fit high lock bolt installation process is as follows: drawing lines, making primary holes, reaming holes, making chamfer angles, installing high-lock bolts and installing high-lock nuts.
The interference fit high lock bolt polish rod and the mounting hole on the part have a certain interference quantity, so the process specification PS D2112 'high lock bolt mounting' prescribes that the interference fit high lock bolt is driven into the part by a riveter and a smooth steel punch until the nail head is in place before the high lock nut or the nut is mounted. For the space open part, the bolt can be installed according to the method of the technological specification, and for the small space part, because the construction space is too small, a riveter and a steel punch cannot be placed, and an interference fit high-lock bolt cannot be driven into the bolt hole; the process specification PS D2112 "installation of high lock bolts" also specifies: for a particular high lock bolt diameter, the high lock bolt is allowed to be pulled in by tightening the nut to a specified torque value, but this method does not allow the use of a single hex break high lock nut. The most widely used high lock bolts are single hexagonal screw-off high lock nuts, so that the high lock bolts cannot be pulled into the bolt holes by using a method of tightening the nuts. The bolt can be installed in place only by adopting a knocking mode, and the bolt is inconvenient to apply force due to narrow space, high in installation difficulty and low in bolt installation efficiency, and the head and parts of the bolt are easy to damage in the knocking process. The prior art and tools cannot ensure the requirements of high quality and high efficiency of aircraft assembly.
