[0152] Step 12: A chuck 170 for disassembling the piston rod assembly and the dust cover of the shock absorber is arranged on the shock absorber, and the second vertical drive assembly 143 is driven to start, so as to drive the positioning mounting platform 141 and the positioning clamping tooling 142 to move upward until the chuck 170 above the shock absorber is engaged with the arc-shaped tooth extraction hook 162 of the auxiliary disassembly chuck 160;

[0153] Step 13: Drive the first vertical drive assembly 133 to move, drive the clamping plate 131 and the clamping clamp 132 to move downward, and automatically clamp the dust cover, that is, the left clamping jaw 1321 moves toward each other along the first slide rail 1323 and the right clamping jaw 1322 moves along the second slide rail 1324, and the shock absorber rotation drive device 120 drives the chuck 170 and the upper node lifting ear to rotate. Since the dust cover is clamped, the dust cover is loosened.

[0154] Further, after step 11, the process of stretching the shock absorber and disassembling the threaded ring is as follows: after the dust cover is disassembled, the second vertical drive assembly 143 is driven to start, driving the positioning mounting platform 141 and the positioning clamping fixture 142 to move downward, and at the same time driving the lower node of the shock absorber to move downward and stretch; a threaded ring disassembly chuck with carbide pins is placed on the two pin holes on the upper end face of the threaded ring, and the first vertical drive assembly 133 is driven to move, and the clamping plate 131 and the clamping fixture 132 are driven to move upward again, and the threaded ring disassembly chuck is engaged with the tooth extraction hook of the auxiliary disassembly chuck 160; the shock absorber rotation drive device 120 is driven to drive the threaded ring disassembly chuck to rotate, and the threaded ring is loosened;

[0155] The first vertical drive assembly 133 is actuated to drive the clamping plate 131 and the clamping fixture 132 to move downward, remove the threaded ring disassembly chuck, loosen the positioning fixture tooling, and use the auxiliary lifting device to move the shock absorber to the next station for oil drainage and sub-component disassembly.

[0156] The present application realizes one-stop efficient disassembly of node hanging ear rotation drive, dust cover automatic clamping, double-node positioning stretching and thread ring rotation disassembly, saving 50% of manpower and improving efficiency by 75%.
