[0021] like Figures 1-4 As shown, a tooling fixture suitable for a JWZ-1 viscous damper includes a base 1, a vertical fixing bolt 2, a horizontal fixing bolt 3, and a connecting column 4. A fixing block 5 is vertically mounted on the base 1, and the horizontal fixing bolt 3 is threaded onto the fixing block 5. The horizontal fixing bolt 3 is used to cooperate with the fixing block 5 to fix the inclined opening end of the damper. The connecting column 4 is threaded onto the base 1, and the top of the connecting column 4 is threaded onto the vertical fixing bolt 2. The vertical fixing bolt 2 is used to clamp and fix the horizontal opening end of the damper onto the connecting column 4. The side of the fixing block 5 facing the horizontal fixing bolt 3 is an inclined surface that matches the shape of the damper end face. The inclined surface has a first limiting groove 6 for accommodating the inclined opening end of the damper. By adjusting the length of the threaded connection between the lower end of the connecting column 4 and the base 1, the height of the upper end of the connecting column 4 can be adjusted, thereby adjusting the installation height of the inclined opening end of the damper.

[0022] In one embodiment, the threaded rod of the horizontal fixing bolt 3 passes through the first limiting groove 6 and is threadedly connected to the fixing block 5. The horizontal fixing bolt 3 has a second limiting groove 7 on the side facing the fixing block. The second limiting groove 7 is used to cooperate with the first limiting groove 6 to fix the inclined opening end of the damper.

[0023] In one embodiment, the vertical fixing bolt 2 and the connecting column 4 are each provided with a third limiting groove 8 on their opposite sides for fitting and fixing the horizontal opening end of the damper. The threaded rods of the horizontal fixing bolt 3 and the vertical fixing bolt 2 are used to pass through the inclined opening end and the horizontal opening end of the damper respectively to fix the damper.

[0024] In one embodiment, the base 1 is a C-shaped bent plate.

Next, pass the threaded rod of the horizontal fixing bolt 3 through the connecting hole of the inclined opening end. Connect the fixing block 5 and rotate the horizontal fixing bolt 3 so that the second limiting groove 7 fits against the other surface of the inclined opening end, clamping and fixing the inclined opening end on the fixing block 5. Then, place the horizontal opening end on the third limiting groove 8 on the top of the connecting column 4. Pass the threaded rod of the vertical fixing bolt 2 through the connecting hole of the horizontal opening end and connect it to the connecting column 4, and rotate the vertical fixing bolt 2 to fix the horizontal opening end. Confirm that both ends of the damper are firmly fixed without loosening or displacement. Check whether the entire fixture is stable, ensuring that it will not deform or shift during measurement. Then, using the reference point indicated on reference point indicator 9 as the reference point, measure the fixed damper using appropriate measuring tools to obtain the required data. Based on the measurement data, perform service condition inspection or maintenance assessment of the helicopter components.
