Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5As shown, a wire harness cutting device for automobile wire harness production includes a base 1, a workbench 2 is installed on the top of the base 1, the workbench 2 is used to guide the wire harness, so that the device is more accurate when cutting the wire harness, a fixing mechanism 3 is arranged on the surface of the workbench 2, the fixing mechanism 3 is used to fix the wire harness, so that the fixing mechanism 3 can fix one end of the wire harness, which is convenient for collective movement of the wire harness, a mounting frame 4 is installed on the surface of the base 1, the mounting frame 4 is U-shaped, and a cutting mechanism 5 is installed in the inner cavity of the mounting frame 4, the cutting mechanism 5 is used to cut the wire harness on the surface of the workbench 2, so that the device can cut more wire harnesses at one time, connecting frames 6 are installed on both sides of the cutting mechanism 5, the connecting frame 6 is L-shaped, and a protective mechanism 7 is installed on the surface of the connecting frame 6, and the cutting mechanism 5 can be protected under the action of the protective mechanism 7, so that the cutting mechanism 5 can be cut without When cutting the wire harness, the blade can be shielded to prevent the staff from accidentally touching the cutting mechanism 5 and getting injured, thereby improving the safety of the staff at work. A magnet 12 is fixed inside the mounting frame 4, and the magnet 12 is used in conjunction with the protective mechanism 7. A fixing frame 8 is fixedly connected to one side of the base 1, and a guide wheel 9 is installed inside the fixing frame 8. The guide wheel 9 is used to guide the wire harness inside the workbench 2. A positioning plate 10 is fixed inside the fixing frame 8, and a squeezing mechanism 11 is provided on the surface of the positioning plate 10. The squeezing mechanism 11 is used in conjunction with the guide wheel 9 to squeeze the wire harness. With the cooperation of the fixing mechanism 3, the wire harness can be tighter when moving, so that the size of the wire harness is more accurate. At the same time, the squeezing mechanism 11 cooperates with the guide wheel 9 to limit the wire harness so that it will not move easily, further improving the accuracy of the wire harness when cutting.

[0025] The protection mechanism 7 includes a gear 71, which is rotatably connected to the mounting frame 4. There are four gears 71, and they cooperate with each other in pairs. A protection shell 72 is fixedly connected to one side of the gear 71. The protection shell 72 is an L-shaped structure. The protection shell 72 is used in conjunction with the cutting mechanism 5. A semi-rack plate 73 is fixedly connected to the surface of the connecting frame 6. The surface of the semi-rack plate 73 meshes with the gear 71. Under this action, when the cutting mechanism 5 moves downward, the protective shell 72 can be driven to rotate through the semi-rack plate 73, so that the protective shell 72 is not It will affect the cutting of the wire harness by the cutting mechanism 5, and when the cutting mechanism 5 returns to its original position, the protective shell 72 can return to its original position to block the cutting mechanism 5, thereby reducing the situation where the staff accidentally touches the cutting mechanism 5 and gets injured. The material of the protective shell 72 is iron, and the protective shell 72 is used in conjunction with the magnet 12. Under this action, after the half-rack plate 73 rotates the protective shell 72 ninety degrees, the half-rack plate 73 no longer meshes with the gear 71, and the magnet 12 can fix the protective shell 72 under the action of its material, so that the protective shell 72 will not move easily.

[0026] The extrusion mechanism 11 includes a connecting plate 111, the surface of which is slidably connected to the inner wall of the fixing frame 8, under which the connecting plate 111 can be more stable when moving and will not easily shift its position. The top of the connecting plate 111 is fixedly connected with an extrusion wheel 112, the number of which is the same as the number of the guide wheels 9, and the positions of the extrusion wheels 112 and the guide wheels 9 correspond to each other. The bottom of the connecting plate 111 is fixedly connected with a guide rod 113, and the other end of the guide rod 113 penetrates to the bottom of the positioning plate 10 and is slidably connected to the inner wall of the penetration point. A compression spring 114 is fixedly connected to the bottom of the plate 111, and the other end of the compression spring 114 is fixedly connected to the positioning plate 10. Under this action, the compression spring 114 can always provide thrust to the connecting plate 111, so that the extrusion wheel 112 and the guide wheel 9 can squeeze the wire harness, so that the wire harness can be tighter. The guide rod 113 is located inside the compression spring 114, and the guide rod 113 is used in conjunction with the compression spring 114. Under this action, the compression spring 114 can be guided during the compression and rebound process, so that it will not easily have a large position deviation.

[0027] It is worth noting that the technical features such as the workbench 2, mounting frame 4 and cutting mechanism 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0028] Working principle: first, the wire harness to be cut is passed through between the guide wheel 9 and the extrusion wheel 112 and then fixed with the fixing mechanism 3. After being fixed in sequence, the fixing mechanism 3 is moved to drive the wire harness to move, so as to fix the length of the wire harness. When the wire harness moves, the guide wheel 9 and the extrusion wheel 112 can squeeze the wire harness, so that the wire harness can be tighter, reducing the bending of the wire harness and causing its length to be inaccurate. After the fixing mechanism 3 moves to a suitable position, the cutting mechanism 5 is turned on to cut the wire harness. When the cutting mechanism 5 moves, it will drive the half-rack plate 73 through the connecting frame 6 to rotate the gear 71, and then the protective shell 72 can be driven to rotate under the action of the gear 71, so as to release the protection of the cutting mechanism 5, and then the cutting mechanism 5 cuts the wire harness. After cutting, the cutting mechanism 5 returns to its original position, and the protective shell 72 blocks the cutting mechanism 5 again under the cooperation of the half-rack plate 73 and the gear 71.
