2. the wire harness to be cut penetrates through the transverse correction guide rail 22, the guide conveying limiting strip 6 and the vertical correction guide rail 23, then the wire harness penetrates through the auxiliary guide frame 8 and the first wire splitter 82, and the wire harness is pulled to the right side of the machine base 1 by means of the wire clamp 7 (the direction opposite to the machine base 1 is taken as a reference);

3. the telescopic arm 32 drives the two shearing knives 31 to move oppositely, and meanwhile, the two wire stripping knives 41 also move oppositely to shear the left end of the wire harness and cut the wire skin at the left end;

4. the wire clamping device 7 pulls the right end of the wire harness to move right continuously, the wire skin is stripped from the outside of the wire core under the blocking action of the wire stripping knife 41, and wire stripping operation is finished;

5. the operator sleeves the wire size at the two ends of the sheared wire harness, places the wire harness near the collecting head 51 for identifying the wire size, the collecting head 51 transmits the wire size parameters to the controller, and the controller transmits the parameters to the wire size display screen 91 for displaying.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
