Problems solved by technology

[0003]However, in the actual installation process, it often requires multiple manual attempts: the bolt head is difficult to locate, and this depends entirely on the operator's experience, resulting in double interlocking The installation efficiency of the double interlocking ring is low, and it is often necessary to find the position of the bolt head and complete the installation of the double interlocking ring after many manual attempts; in addition, it is very easy to make the tightening torque of the bolt lower than Or higher than the specified torque range, leaving a safety hazard for the subsequent operation of the aero-engine

Abstract

The invention relates to a multi-linkage locking ring mounting tool which is used for sleeving multi-linkage locking rings on at least two bolts on an aero-engine casing. The multi-linkage locking ring mounting tool comprises a mounting seat, at least two mounting heads, at least two force limiting wrenches and an indicator, wherein the at least two mounting heads are rotatably arranged on the mounting seat respectively; one end of each mounting head is provided with an internal spline hole matched with a bolt spline; an external spline corresponding to the internal spline hole is formed in the peripheral surface of each mounting head; the force limiting wrenches are detachably mounted at one end, away from the internal spline hole, of each mounting head; rotating axes of the force limiting wrenches coincide with the center line of the internal spline hole; and the indicator comprises an indicating rod arranged on the mounting seat; and the indicating rod can be clamped into key grooves of the external splines so as to indicate the circumferential position of the bolt spline. According to the multi-linkage locking ring mounting tool of the embodiment, the multi-linkage locking rings can be assembled in place in one time; the attempt time is shortened; and the mounting efficiency of the multi-linkage locking rings is improved.

Description

technical field [0001] The present disclosure relates to the field of aero-engine assembly, in particular to a multi-interlock ring installation tool and an installation method. Background technique [0002] Threaded connection is the main connection form between aero-engine casings. In order to prevent the threaded connection from failing, mechanical anti-loosening measures are usually adopted. Taking the double interlocking ring in the multi-interlocking ring as an example, the double interlocking ring is set on two The head of the adjacent bolt, by using the double interlocking ring with the opening shape consistent with the spline shape of the bolt head, so that once the double interlocking ring is installed on the heads of the two adjacent bolts, the two adjacent bolts will It realizes interlocking and cannot rotate, so as to realize the common anti-loosening of two bolts. [0003] However, in the actual installation process, it is often necessary to manually try many ...
