Problems solved by technology

However, because the tooling equipment and the fixed guide rail platform cannot be closely bonded, there will be a certain gap. In large-scale equipment with large mass and large inertia, if only relying on the pin to limit the position, there will be higher requirements for the size of the pin. Therefore, the traditional positioning The pin will be subjected to shear force brought by external force and bending moment due to excessive clearance, and eventually the pin will bend and cause positioning failure

Abstract

The invention discloses a fast positioning bolt locking device, which comprises a flange seat provided with an internal thread inside, a pressing nut provided with an external thread on the outside, a positioning pin embedded in the pressing nut, and a fixing pin for fixing the positioning pin. Pin seat, the middle part of the fixed pin seat is provided with a fixing hole, the end is provided with a flange; The flange plate of the pressing nut matches the flange plate at the end of the fixed pin seat, and the other end of the pressing nut placed in the flange seat is provided with a tooth cover; the middle part of the positioning pin is provided with a tooth plate matching the tooth cover. The invention makes up the gap between the tooling equipment and the fixed guide rail platform through the staged engagement and separation of the tooth cover and the tooth plate, and generates a great locking force, which can effectively solve the disadvantages of the traditional positioning method, and achieve fast and convenient locking. Tight positioning action; to avoid bending damage caused by the bolt, resulting in positioning failure, suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of assembling, positioning and locking equipment for aircraft components, in particular to a fast positioning bolt locking device. Background technique [0002] Due to the large dimensions and complex structure of the parts of the aircraft fuselage, in order to adapt to the aircraft structure and ensure the openness of aircraft assembly and processing, the volume and weight of aircraft assembly tooling equipment also increase accordingly. And with the popularization of digital manufacturing and processing, large-scale assembly tooling equipment needs to have the characteristics of production lines, which can be transferred along the fixed guide rails. After the transfer process, the tooling equipment needs to rely on stable and reliable positioning and locking devices to achieve its own positioning. However, because the tooling equipment and the fixed rail platform cannot be closely fitted, resulting in a ce...
