An indirect torque application device

Abstract

The invention discloses an indirect torque applying device, and used for applying a tightening torque between a head cover and a barrel body. The indirect torque applying device comprises a base, a center boss, a side boss and a connecting rod, wherein the center boss sleeves an exhaust pipe; the side boss is in contact with the inner wall of the head cover through an igniter mounting hole in the head cover; the connecting rod is used for realizing torque transmission; three work stations are designed on the base; the mounting station is positioned at a middle notch in the base; the locking work station or disassembling station is formed by clockwise rotation; or the disassembling station or locking work station is formed by counterclockwise rotation. According to the indirect torque applying device, through the design of the torque device, the problem that the torque cannot be directly applied due to that a hexagonal structure is not designed on the barrel body and the head cover in the axial direction is solved.

Description

technical field [0001] The invention relates to a torque applying device, especially an indirect torque applying device. Background technique [0002] The gas generator is mainly composed of a head cover and a cylinder body. The head cover and the cylinder body are connected by threads, and there is a requirement for tightening torque between the head cover and the cylinder body. [0003] However, the head cover and cylinder axis of many gas generators are not designed with a hexagonal structure for easy clamping and force application. Although there are igniter joints and pressure measuring nozzles on the side, both structures are welded to the head cover body. Suitable for heavy loads. [0004] Therefore, there is an urgent need for a torque applying device to solve the problem that the cylinder is fixed and there is no hexagon on the axis so that the torque cannot be directly applied. Contents of the invention [0005] The object of the present invention is to provide...
