[0026] Working principle:

[0027] Auxiliary fixing process of the anti-drop elastic retaining ring:

[0028] The operator puts the anti-drop elastic retaining ring on the surfaces of the two arc-shaped blocks 306, connects the external power supply of the hydraulic cylinder 301, and starts the telescopic end of the hydraulic cylinder 301 to extend, driving the push block 303 to move. The push block 303 pushes the two clamping arms 304 to move to both sides. The clamping arms 304 drive the two arc-shaped blocks 306 to move synchronously. The arc-shaped blocks 306 move outward and expand inside the anti-drop elastic retaining ring, pressing against the inner surface of the anti-drop elastic retaining ring for fixation, which is convenient for subsequent chamfer cutting on the surface of the anti-drop elastic retaining ring. According to the above operation, after the chamfer cutting is completed, start the telescopic end of the hydraulic cylinder 301 to shorten again, driving the surface of the arc-shaped block 306 to move away from the inner surface of the anti-drop elastic retaining ring, which is convenient for the operator to take it out, and the auxiliary fixing process of the anti-drop elastic retaining ring is completed.

[0029] Chamfer cutting process of the anti-drop elastic retaining ring:

[0030] The operator connects the external power supplies of the third motor 10 and the second motor 5, starts the output shaft of the third motor 10 to rotate, driving the auxiliary fixing device 3 and the anti-drop elastic retaining ring to rotate at high speed, starts the output shaft of the second motor 5 to rotate, driving the second threaded rod 6 to rotate. The second threaded rod 6 rotates to drive the threaded block 7 and the support plate 8 to move horizontally to the right. The support plate 8 drives the cutting tool 207 to move to the right. After the surface of the cutting tool 207 contacts the surface of the anti-drop elastic retaining ring, it cuts the anti-drop elastic retaining ring.

[0031] Auxiliary adjustment process of the cutting tool angle for processing the anti-drop elastic retaining ring:

[0032] When it is necessary to adjust the angle of the cutting tool, connect the external power supply of the first motor 201, start the output shaft of the first motor 201 to rotate, drive the first threaded rod 203 to rotate, the first threaded rod 203 rotates to drive the slider 204 to move upward, the slider 204 drives the rotating cylinder 205 to rotate, the rotating cylinder 205 drives the tool holder 206 and the cutting tool to rotate. When it rotates to the appropriate angle, stop the output shaft of the first motor 201 from rotating. According to the above operation, when it is necessary to adjust the angle of the cutting tool 207 in the reverse direction, start the output shaft of the first motor 201 to reverse again to drive the rotating cylinder 205 to rotate in the reverse direction. After the rotating cylinder 205 drives the cutting tool 207 to rotate to the appropriate angle, stop the output shaft of the first motor 201 from rotating, and complete the process of auxiliary adjustment of the cutting tool angle for the processing of the anti-detachment elastic retaining ring.
