The cone sleeve fixing plate 205 is fixed to the front end of the bracket 201 by screws, and a through hole is opened on the cone sleeve fixing plate 205. The cone sleeve 203 is arranged at the lower part of the cone sleeve fixing plate 205, and the major diameter of the cone sleeve 203 is the same as the diameter of the through hole. The guide block 204 is arranged on the cone sleeve fixing plate 205, and the guide block 204 cooperates with the guide groove on the pressure head. A plurality of fixed blocks 206 are equidistantly arranged on the cone sleeve fixing plate 205, and the rotating support block 210 is fixed on the fixed block 206 through a pin 212, and a torsion spring 211 is arranged between the rotating support block 210 and the pin 212.

[0038] Furthermore, a relief space 213 is provided on the cone sleeve 203 to facilitate the assembly of the snap ring. When the pressure head moves downward for press-fitting, the rotating support block 210 can rotate downward, so that the snap ring leaves the rotating support block 210 and shrinks inward under the action of the cone sleeve 203. The cone sleeve 203 has a high concentricity with the dual clutch, thereby ensuring the concentricity of the snap ring and the snap ring groove when the snap ring is assembled.

[0039] Furthermore, when the cylinder 208 drives the guide mechanism to move downward, the lower edge of the cone sleeve 203 is flush with the upper edge of the snap ring groove.

[0042] S1, placing the snap ring on three rotating support blocks 210;

[0043] S2, operate the cylinder 208 to move the guide device downward until the position switch 209 detects a position signal, indicating that the lower edge of the taper sleeve 203 is flush with the upper edge of the snap ring groove;

[0044] S3, driving the pressure head to move downward so that it contacts the retaining ring first;

[0045] S4, continue to push the snap ring downward, so that the rotating support block 210 rotates under the action of the torsion spring 211;

[0046] S5. The clamping ring leaves the rotating support block 210 under the guidance of the tapered sleeve 203 and shrinks inwards;

[0047] S6, the snap ring continues to move until it completely leaves the lower end of the cone sleeve 203 and enters the snap ring groove on the gearbox;
