Abstract

The invention relates to a folding force-limiting wrench switching mechanism for a deep cavity, which comprises a head folding part, a long arm part and a positioning part, wherein the head folding part comprises an adapter, a switching piece and a zipper assembly; the side surfaces of the adapter and the switching piece are provided with grooves, and a torsion spring is arranged in the grooves; the other end of the switching piece is connected with a long arm of the long arm part; the top end of the long arm is connected with a positioning plate; the positioning part comprises a positioning disc, a cushion block and a tightening head; the positioning disc is provided with installation holes which are the same as screws to be screwed on a unit body to be assembled in number and coaxial with the screws to be screwed on the unit body to be assembled, bushings are arranged in the installation holes; the cushion block is provided with a straight through hole and can be placed on the positioning disc to adjust the height difference between the adapter and the positioning disc; the tightening head is inserted into the installation holes of the positioning disc through the positioning plate and the cushion block; and the zipper assembly comprises a handle and a steel wire connected with the handle, and the steel wire penetrates through the long arm, the switching piece and the torsionspring to be connected with the adapter. The mechanism is not limited by using space, and is simple to operate and accurate in torque conduction.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, in particular to a folding force limiting wrench transfer mechanism for a deep cavity. Background technique [0002] During the assembly process of the core components of the aero-engine, the installation of the rotor units at all levels needs to be carried out in a narrow inner cavity, and the torque is limited. Therefore, the traditional limit wrench or ordinary adapter cannot meet the actual use requirements. Therefore, there is an urgent need for a deep cavity torque wrench transfer mechanism to solve the above problems. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a folding force limiting wrench transfer mechanism for deep cavity, which is not limited by the use space, and has simple operation and accurate torque transmission. [0004] The present invention adopts following technical scheme to realize: [0005] A fold...
