Abstract

The invention relates to a sealing element mounting and dismounting tool. The tool comprises a clamping jaw (50), an adapter rod (60), a first driving mechanism (70) and a second driving mechanism (80). The clamping jaw (50) is used for being inserted into a sealing element (10) and is used in cooperation with a cooperative part arranged on the inner wall of the sealing element (10) to enable theclamping jaw (50) to be fixed relative to the sealing element (10). The adapter rod (60) is connected with the clamping jaw (50). The first driving mechanism (70) is arranged between the clamping jaw(50) and the adapter rod (60) and used for driving the clamping jaw (50) to get close to or get away from the adapter rod (60) in the direction perpendicular to the axis of the adapter rod (60). The second driving mechanism (80) is used for driving the adapter rod (60) to move along the axis of the adapter rod (60) so as to drive the clamping jaw (50) and the sealing piece (10) to move. With the sealing element mounting and dismounting tool, damage caused to a sealing element can be reduced in the dismounting process, it is avoided that other parts also need to be dismounted, the dismounting cost is obviously reduced, and meanwhile the tool can also be used for assembling the sealing element.

Description

technical field [0001] The invention relates to the technical field of dismounting tooling, in particular to a seal assembly and disassembly tool. Background technique [0002] There are multiple rotating parts in an aero-engine. In order to reduce the friction between the rotating parts and the fixed parts, lubricating oil is usually injected into the space between the rotating parts and the fixed parts. In order to achieve a better lubrication effect, it is necessary to The oil filling space is sealed. [0003] The oil channel seal of lubricating oil in aero-engines is generally sealed by a sealed runway. There is an apron between the sealed runway and the parts to be sealed. Although the apron can improve the sealing effect, it requires a large force when disassembling or assembling the sealed runway. External force, to overcome the friction between the rubber ring and the parts to be sealed, the sealing runway can be pulled out or loaded, and it is difficult to assemble...
