In this method, the movement is disassembled by offsetting the gravity of the pendulum assembly with floating oil, thereby increasing the damping of the pendulum assembly during the disassembly process and preventing the pendulum assembly from being damaged under gravity.

The inner wall of the constraint frame 18 is provided with a convex strip 24 that is concave-convexly matched with the strip groove 23. The force nut 19 is threadedly connected to the hollow cylindrical section 21 and is used to rotate it to make it approach the hollow truncated cone section 20 along the hollow cylindrical section 21, so as to apply force or unload force on the constraint frame 18 to achieve the scaling of the hollow truncated cone section 20. The disassembly tool of the movement is used to disassemble the movement 02 in the quartz accelerometer.

[0060] This embodiment further provides a method for disassembling a quartz accelerometer, using the above-mentioned quartz accelerometer disassembly device, and comprising the following steps:

[0061] Step 1: Use the plugging piece disassembling tool to disassemble the plugging piece 07 on the servo circuit 03; the outer diameter of the plugging piece 07 is 4.5mm and the thickness is 0.5mm. The specific process of disassembling the plugging piece 07 using the plugging piece disassembling tool is as follows:

[0062] Place the plug disassembly tool on the surface of the servo circuit 03, the open end face of the U-shaped limiting bracket 14 abuts against the surface of the servo circuit 03, and the active end of the self-tapping screw 15 is located above the plug 07; rotate the self-tapping screw 15 so that the active end of the self-tapping screw 15 opens a through hole with a diameter of 2 to 3 mm on the plug 07, and then use needle-nosed pliers to tear off the remaining plug 07 at the position of the through hole, so that the soldering pad of the servo circuit 03 can be completely protected.

[0063] Step 2: Use the servo circuit disassembly tool to separate the servo circuit 03 and the housing 01; specifically, the following steps are included:

[0064] Step 2.1, the servo circuit 03 and the end of the housing 01 away from the servo circuit 03 are respectively sleeved in the annular elastic pads 26 on the inner walls of the hollow truncated cone sections 20 of the two shrinking frames 17, the two restraining frames 18 are respectively sleeved outside the two shrinking frames 17, and the two force nuts 19 are respectively threadedly connected to the hollow cylindrical sections 21 of the two shrinking frames 17;

[0065] Step 2.2, respectively rotate the two force nuts 19 to make them approach the hollow truncated cone section 20 along the corresponding hollow cylindrical section 21, thereby applying force to the two restraining frames 18, so that the two restraining frames 18 squeeze the two hollow truncated cone sections 20 respectively, and the two hollow truncated cone sections 20 respectively correspond to and fasten the servo circuit 03 and the housing 01;

[0066] Step 2.3: Rotate the two restraining frames 18 in opposite directions to separate the servo circuit 03 and the housing 01.

[0067] Step 3, remove the watch movement 02 from the housing 01, and use the above-mentioned watch movement disassembly tool to disassemble the watch movement 02; the specific disassembly steps are:

[0068] Step A1, using 3D simulation software to simulate and calculate the density ρ of the pendulum assembly 04; preparing floating oil and pouring it into the open container 8, the density of the floating oil ρ1 = 0.8ρ ~ ρ, then placing the watch movement 02 in the semi-cylindrical groove 80, and the two torquers 05 of the watch movement 02 are respectively adsorbed on the two magnetic blocks 10;

[0069] Step A2, by rotating one of the force-adding heads 90 to drive the corresponding force-adding thrust rod 91 to apply force to one of the torquers 05, until the force value displayed on the pressure display screen 13 is 0.9m-1.1m, where m is the repulsive force value between the two torquers 05 (in this embodiment, until the force value displayed on the pressure display screen 13 is equal to the repulsive force value 110N between the two torquers 05), to ensure that after the annular abdominal belt 06 is subsequently torn open, the repulsive force between the two torquers 05 is at a critical value, and the two torquers 05 will not suddenly bounce open under the repulsive force because the force-adding tooling 9 is too small, resulting in an increased risk of fracture of the pendulum assembly 04, or excessive force causing the pendulum piece of the pendulum assembly 04 to break;

[0070] Step A3: Figure 5 As shown, the annular abdominal belt 06 between the two torquers 05 is torn open, and one of the force-adding heads 90 is driven by the corresponding force-adding thrust rod 91 to unload the force to one of the torquers 05 by rotating in the opposite direction, so that the two torquers 05 are respectively moved to the two sides of the open container 8 under the adsorption effect of the corresponding magnetic blocks 10 and the repulsive force between the two torquers 05, until the pendulum assembly 04 is in a suspended state in the floating oil, and the disassembly of the quartz accelerometer is completed.

[0071] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
