[0043] As Figures 1 to 4 shown, it is a wire harness cutting device of the present utility model for cutting wire harnesses, including a connection seat 100, a cutting mechanism 200 assembled on the connection seat 100, and a pressing mechanism 300 assembled on the connection seat 100.

[0044] Among them, the cutting mechanism includes a support plate 21 fixed to the front end face of the connection seat 100 and a cutting module 22 arranged above the support plate 21; the cutting module 22 moves downward to cut the wire harness. The pressing mechanism 300 includes a support component 32 and a pressing component 31 fixed to the front end face of the connection seat 100. The support component 32 and the pressing component 31 are arranged vertically aligned and cooperate with each other; the pressing component 31 includes a guide rail 311 vertically arranged on the front end face of the connection seat 100, a slider 312 slidably connected to the guide rail 311, and a first roller 313 rotatably connected to the front end face of the slider 312. A counterweight 314 is connected to the slider 312; the support component 32 includes a connection block 321 fixed to the front end face of the connection seat 100 and a second roller 322 rotatably connected to the front end face of the connection block 321. The first roller 313 and the second roller 322 are arranged in alignment. During the actual processing, the wire harness passes through the gap between the first roller 313 and the second roller 322; under the action of gravity, the first roller 313 moves downward along the guide rail 311 to press the wire harness. At the same time, a counterweight 314 is arranged on the slider 312, which can ensure the downward pressure of the first roller 313, press the wire harness to improve the stability during the transmission of the wire harness, and avoid jitter affecting the cutting quality of the wire harness.

[0045] Specifically, a plurality of pressing mechanisms 300 are provided and arranged horizontally and transversely along the transmission direction of the wire harness; in this embodiment, pressing mechanisms 300 are provided on both sides of the cutting mechanism 200, which can press both ends of the wire harness to be cut and avoid the position error of the cutting caused by the deviation of the wire harness during the cutting process.

[0046] Specifically, two counterweights 314 are provided and symmetrically fixed on both sides of the slider 312 to ensure the balanced force and vertical downward pressure of the slider 312.

[0047] Specifically, a first rotating bearing 315 is fixedly provided on the front end face of the slider 312. The rear side of the first roller 313 extends out a first rotating shaft 316, and the first rotating shaft 316 is connected with the first rotating bearing 315 in a matching manner; a second rotating bearing 323 is fixedly provided on the front end face of the connecting block 321. The rear side of the second roller 322 extends out a second rotating shaft 324, and the second rotating shaft 324 is connected with the second rotating bearing 323 in a matching manner; the cooperation of the first rotating shaft 316 and the first rotating bearing 315, and the cooperation of the second rotating shaft 324 and the second rotating bearing 323 can reduce the rotation resistance of the first roller 313 and the second roller 322 and ensure the passage of the wire harness.

[0048] Specifically, guide grooves 317 are provided on the outer walls of both the first roller 313 and the second roller 322. In this embodiment, the cross-sectional shape of the guide groove 317 is triangular. When the wire harness passes between the first roller 313 and the second roller 322, the wire harness abuts against the side wall of the guide groove 317, thereby playing a role in limiting the wire harness. During the transmission process of the wire harness, it is always located in the guide groove 317 to avoid detachment.

[0049] Specifically, as Figure 2 shown, the cutting module 22 includes a driving cylinder 221 fixed on the front end face of the connecting seat 100 and a cutter 222 connected to the transmission end of the driving cylinder 221; the driving cylinder 221 drives the cutter 222 to move downward to cut the wire harness. The cutting module 22 further includes a knife clamping head 223. Specifically, an installation groove 224 is provided on the knife clamping head 223, the upper end of the cutter 222 is installed in the installation groove 224, and the knife clamping head 223 and the cutter 222 are provided with aligned hole positions, and bolts are locked into the hole positions to realize the locking of the cutter 222 and the knife clamping head 223; the driving cylinder 221 drives the upper end connected to the knife clamping head 223.

[0050] Specifically, as Figure 1 and Figure 4 shown, limiting seats 400 are symmetrically distributed on both sides of the support plate 21, and wire passing holes 41 are provided through the limiting seats 400; the wire harness is transmitted through the wire passing holes 41 to ensure that the wire harness passes horizontally through the cutting mechanism and ensure the cutting quality.

[0051] Specifically, the wire harness cutting device of the present utility model further includes a guiding mechanism 500. The guiding mechanism 500 includes a plurality of guiding wheels 51 rotatably connected to the front end face of the connecting seat 100. The plurality of guiding wheels 51 are distributed vertically and staggeredly. The wire harness passes between the guiding wheels 51, and thus the guiding wheels 51 play a guiding role for the wire harness to avoid deviation.

[0052] Specifically, the wire harness cutting device of the present utility model further includes a winding mechanism 600. The winding mechanism 600 includes a rotating motor 61, a rotating disc 62, and a wire winding disc 63. The rotating motor 61 is arranged at the rear side of the connecting seat 100, the rotating disc 62 is arranged at the front end of the connecting seat 100, the rotating motor 61 is drivingly connected to the rotating disc 62, and the wire winding disc 63 is assembled and connected to the rotating disc 62. The rotating motor 61 drives the rotating disc 62 to rotate, driving the wire winding disc 63 to rotate. Before processing, one end of the wire harness is fixed on the wire winding disc 63, the rotating motor 61 is started, and the rotating motor 61 drives the rotating disc 62 and the wire winding disc 63 to rotate, driving the wire harness to be transmitted towards the winding mechanism 600.

[0053] The working principle of the wire harness cutting device related to the present utility model is as follows:

[0054] One end of the wire harness is fixed in the winding mechanism 600, and the rotating motor 61 drives the wire winding disc 63 to rotate. When it is wound to a preset length, the rotating motor 61 stops working, and the cutting mechanism 200 cuts the wire harness. Thus, the winding and cutting of the wire harness with a preset length are completed.

[0055] Compared with the prior art, the wire harness cutting device related to the present utility model is used for cutting wire harnesses, and is provided with a cutting mechanism 200 and a pressing mechanism 300. The cutting mechanism 200 includes a support plate 21 and a cutting module 22. The cutting module 22 moves downward to mechanically cut the wire harness on the support plate 21 to ensure the cutting quality. The pressing mechanism 300 includes a support assembly 32 and a pressing assembly 31. The pressing assembly 31 includes a guide rail 311, a slider 312, and a first roller 313, and a counterweight 314 is arranged on the slider 312. The first roller 313 presses the wire harness under the action of gravity, improving the conveying smoothness of the wire harness and avoiding the influence of jitter on the cutting quality. At the same time, the first roller 313 can move up and down along the guide rail 311 to adapt to wire harnesses of different sizes.

[0056] The above only expresses the preferred technical solutions of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and deformations.
