[0058] Working principle of the present application:

[0059] The worker puts a plurality of wire harnesses into the guide grooves 13 of the wire harness shelf 2, and then pushes the wire harnesses to move towards the conveying belts 3, so that the ends of the wire harnesses are correspondingly clamped into the wire harness clamping grooves 12 of the conveying belts 3; the two conveying belts 3 synchronously and reversely rotate, and then the wire harnesses can be pulled towards the positioning seat 9 by the friction between the conveying belts 3 and the surface of the wire harnesses, so that the wire harnesses can be straightened by the wire harness clamping grooves 12; after the wire harnesses are straightened, the wire harnesses enter the gathering bin 4, and the wire harnesses are guided by the inner wall of the gathering bin 4 and enter the bundle pipe 20;

[0060] The servo motor 19 is started, the servo motor 19 drives the driving pulley to rotate, and then drives the driven pulley to rotate through the V-belt, so that the rotating sleeve 17 rotates, when the rotating sleeve 17 rotates, the swing pressing block 35 is driven to rotate, the swing pressing block 35 generates extrusion force on the wire harness located in the rotating sleeve 17, and the volute spring 33 has elastic force on the pivot 37, so that the extrusion force of the swing pressing block 35 on the wire harness is not too large;

[0061] The corrugated pipe is placed in the storage bin 6, under the action of gravity, the corrugated pipe enters the falling bin 5, the two motors 23 synchronously drive the two shafts 27 to rotate reversely, so that the rotating discs 7 on the two shafts 27 rotate, and then the clamping grooves 15 on the four rotating discs 7 clamp the lowermost corrugated pipe in the falling bin 5, and then the corrugated pipe is pushed to the lower end of the falling bin 5 with the rotation of the shaft 27, so that the corrugated pipe falls into the positioning groove 21 of the positioning seat 9, and then the shaft 27 stops rotating, at this time, another clamping groove 15 on the rotating disc 7 clamps another corrugated pipe, and the corrugated pipe does not fall down;

[0062] After the corrugated pipe falls into the positioning groove 21, the four clamping cylinders 10 are started synchronously, so that the clamping cylinder 10 drives the clamping plate 22 to move towards the corrugated pipe, so that the clamping plate 22 can clamp the end of the corrugated pipe, and then the translation cylinder 25 is started, the cylinder rod of the translation cylinder 25 is shortened, and then the guide rod 8 is driven to move, and the guide rod 8 penetrates into the corrugated pipe, when the guide rod 8 penetrates out of the corrugated pipe, the folding and unfolding cylinder 24 drives the sliding rod 30 to move, so that the sliding rod 30 drives the hinge rod 32 to swing, and then the hinge rod 32 drives the rotating arm 31 to swing, so that the clamping plates 29 are unfolded, then the translation cylinder 25 drives the guide rod 8 to continue to move, so that the wire harness end enters between the clamping plates 29, then the folding and unfolding cylinder 24 drives the sliding rod 30 to move reversely, so that the clamping plates 29 can be folded and clamp the wire harness end, then the translation cylinder 25 drives the guide rod 8 to move away from the bundle tube 20, so that the clamping plates 29 can pull the wire harness to move away from the bundle tube 20, since the guide rod 8 is coaxial with the corrugated pipe, the wire harness can penetrate out of the corrugated pipe, and does not contact the inner wall of the corrugated pipe, it should be noted that the moving speed of the guide rod 8 matches the conveying speed of the conveying belt 3 at this time, and in the process of pulling the wire harness to penetrate out of the corrugated pipe, the rotating sleeve 17 continuously rotates;

[0063] When the end of the wire harness is threaded through the corrugated tube, the conveying belt 3 stops running, then the clamping jaw cylinder 26 drives the two cutting parts 11 to move relatively close, and then the two cutting parts 11 cut the wire harness, so that the length of the wire harness can be kept consistent. After the end of the wire harness is threaded through the corrugated tube, the retracting and extending cylinder 24 drives the sliding rod 30 to move again, so that the clamping plate 29 is unfolded, and the end of the wire harness is released from the clamping force of the clamping plate 29. Then the worker or the mechanical hand takes out the corrugated tube threaded through the wire harness from the positioning groove 21, and then performs the next cutting and threading operation. In the embodiment, the side end face of the rotating sleeve 17 towards the positioning seat 9 is substantially flush with the surface of the cutting part 11, so that after the cutting part 11 cuts the wire harness, the length of the wire harness exposed from the corrugated tube 20 in the corrugated tube 20 is shorter, and the scattering phenomenon is avoided.

The wire harness auto-potting-cutting device of claim 8, wherein, The end of the harness pipe (20) towards the positioning seat (9) is coaxially connected with a rotating sleeve (17), the peripheral edge of the rotating sleeve (17) is fixedly connected with an ear block (36), the ear block (36) is horizontally connected with a pivot shaft (37), the peripheral edge of the pivot shaft (37) is fixedly sleeved with an oscillating pressing block (35), the peripheral edge of the rotating sleeve (17) is provided with a through slot (34) for the free passing of the oscillating pressing block (35), the wall surface of the ear block (36) is provided with a recessed mounting cavity, the peripheral edge of the pivot shaft (37) is fixedly sleeved with a volute spring (33), the volute spring (33) is arranged in the mounting cavity, and the outer ring end is fixedly connected to the inner wall of the mounting cavity.

10. A harness auto-piping cutting method applied to the piping cutting device of any one of claims 1 to 9, characterized by, Comprise: The corrugated pipe is arranged in the positioning groove (21) of the positioning seat (9) and is limited by the positioning groove (21), the wire harness feeding mechanism feeds the wire harness to the wire harness gathering mechanism, the wire harness gathering mechanism gathers the wire harness into a bundle, the guide rod (8) is driven by the translation air cylinder (25) to move towards the wire harness gathering mechanism, the guide rod (8) coaxially penetrates the corrugated pipe, and the clamping plate (29) is exposed from the corrugated pipe; The expansion and contraction mechanism drives a plurality of clamping plates (29) to expand, the translation air cylinder (25) continues to drive the guide rod (8) to move, so that the end of the wire harness enters between the plurality of clamping plates (29), the expansion and contraction mechanism drives the clamping plates (29) to rotate, so that the plurality of clamping plates (29) gather and clamp the end of the wire harness; The translation air cylinder (25) drives the guide rod (8) to move reversely, so that the guide rod (8) pulls the wire harness to penetrate the corrugated pipe, after the end of the wire harness penetrates the corrugated pipe, the expansion and contraction mechanism drives the clamping plates (29) to expand, so that the end of the wire harness is separated from the clamping state of the clamping plates (29).
