[0032] Example:

[0033] A wire harness 920 cutting device for automotive wire harness production includes a base plate 10 and a wire harness component 90. The top surface of the base plate 10 is provided with a clamping component 20, a pushing component 30, and a cutting component 60. The clamping component 20 and the cutting component 60 are detachably connected to the top surfaces of the two sides of the base plate 10, respectively. The pushing component 30 is fixedly installed on the top surface of the base plate 10 near the cutting component 60. The end face of the pushing component 30 facing the cutting component 60 is provided with a connecting plate 40, and the top surface of the connecting plate 40 is provided with a tensioning component 50.

[0034] The wire harness 90 includes a connector 910 and a wire harness 920. Two connectors 910 are provided and are respectively connected to both ends of the wire harness 920. The two connectors 910 are snapped into the inside of the clamping member 20. The wire harness 920 is wound around the inside of the tensioning member 50, and part of the wire harness 920 is located below the cutting member 60.

[0035] The top surface of the base plate 10 is also provided with a control box 70, which is electrically connected to the push-tightening component 30 and the cut-off component 60 respectively.

[0036] The base plate 10 has a clamping component 20, a pushing component 30, and a cutting component 60 on its top surface. The clamping component 20 primarily secures the wire harness 920. The pushing component 30 maintains the stable position of the wire harness 920 by pushing it towards the cutting component. This ensures that the wire harness 920 maintains proper tension during cutting, thereby improving cutting accuracy. The tensioning component 50 further tensions the wire harness 920, ensuring it remains in the correct position during cutting. The cutting component 60 cuts the wire harness 920. The control box 70 connects the pushing component 30 and the cutting component 60, enabling automated operation. The control box 70 allows for the electrical operation of the pushing component 30 and the cutting component 60, ensuring precise control of the equipment.

[0037] Refer to the attached diagrams in the instruction manual. Figures 1-5 As shown, the clamping component 20 includes a clamping seat 210, which is screwed onto the top surface of the base plate 10. The clamping seat 210 also has two clamping grooves 220 inside its top end. The wire harness 920 is connected inside the clamping groove 220, and the connector 910 is clamped outside the clamping groove 220.

[0038] As explained, the clamping seat 210 is installed on the top surface of the base plate 10 by screwing, thereby ensuring that the clamping seat 210 will not loosen or shift during operation. The top of the clamping seat 210 has two clamping grooves 220 respectively, which are used to fix the wire harness 920. One end of the wire harness 920 is inserted into the clamping groove 220, and the other end of the wire harness 920 is clamped and fixed to the outside of the clamping groove 220 by its external connector 910, preventing the wire harness 920 connector 910 from falling out of the clamping groove 220. This structural design not only improves the stability of the equipment, but also ensures the high-precision positioning of the wire harness 920 and the connector 910 during the entire operation.

[0039] Specifically, the material chosen for the clamping seat 210 possesses excellent mechanical strength and durability to withstand wear and pressure during long-term use. The clamping groove 220 is designed to accommodate the size and shape of the wire harness 920, ensuring it is securely fixed within the clamping seat 210 while facilitating quick replacement by operators. The screw-in connection of the clamping seat 210 allows for fine-tuning on the top surface of the base plate 10 to accommodate wire harnesses 920 of different lengths and specifications. Furthermore, the surface treatment of the clamping seat 210 prevents corrosion, ensuring stable operation of the device even in harsh environments.

[0040] Refer to the attached diagrams in the instruction manual. Figures 1-5As shown, the tensioning component 30 includes a fixing plate 310 and a cylinder assembly 320. The fixing plate 310 is fixedly installed on the top surface of the base plate 10, and the cylinder assembly 320 is fixedly installed on the end face of the fixing plate 310 facing the cutting component 60. The piston top of the cylinder assembly 320 is also connected to a push plate 330, and the push plate 330 is fixedly connected to the connecting plate 40. The tensioning component 50 includes a bearing plate 510 and an adjusting seat 530. At least two bearing plates 510 and two adjusting seats 530 are provided. The two bearing plates 510 are respectively screwed to both ends of the top surface of the connecting plate 40, and the two adjusting seats 530 are respectively screwed to the top surface of the base plate 10 and located on both sides of the cutting component 60.

[0041] Each of the support plates 510 has a limit post 520 on its top surface for tightening the wire harness 920. The adjustment seat 530 is connected to the support plate 510 by an adjustment slide rod 540. One end of the adjustment slide rod 540 is fixed to the support plate 510, and the other end of the adjustment slide rod 540 passes through a snap-fit ​​hole on the top of the adjustment seat 530 and is slidably connected to the adjustment seat 530.

[0042] It is worth noting that the fixing plate 310 is fastened to the top surface of the base plate 10 by a fixing method (such as screws or welding). The cylinder assembly 320 is fixed to the end face of the fixing plate 310 facing the cutting component 60. The piston in the cylinder assembly 320 moves up and down according to the change of air pressure. The top of the piston is connected to the push plate 330. The push plate 330 is pushed by the action of the cylinder, thereby generating thrust. The push plate 330 is fixedly connected to the connecting plate 40. The function of the push plate 330 is to effectively transmit the thrust of the cylinder assembly 320 to the required position to push or press other components. The connecting plate 40 can transmit the thrust to the tensioning component 50, and then the tensioning component 50 can tighten the wire harness 920 to ensure that the wire harness 920 maintains appropriate tension.

[0043] It is further worth noting that there are at least two support plates 510, which are respectively installed at both ends of the top surface of the connecting plate 40 and are securely fixed by screws. There are also at least two adjusting seats 530, which are respectively installed on the top surface of the base plate 10 and located on both sides of the cutting component 60. The adjusting seats 530 are connected to the support plates 510 through adjusting slide rods 540. One end of the adjusting slide rod 540 is fixed to the support plate 510, and the other end passes through the snap-fit ​​hole opened on the top of the adjusting seat 530 and is slidably connected to the adjusting seat 530. During operation, the distance between the adjusting seat 530 and the support plate 510 is changed by the thrust applied by the pushing component 30, thereby adjusting the tension of the wire harness 920. The limiting post 520 provided on the top surface of the support plate 510 can ensure that the wire harness 920 will not shift during the tensioning process and can maintain appropriate tension. The limiting post 520 helps to accurately position the wire harness 920 and prevent them from loosening or shifting due to vibration or external force.

[0044] Refer to the attached diagrams in the instruction manual. Figures 1-5 As shown, the cutting component 60 includes a mounting plate 610, an electric cylinder 620, a first cutter holder 630, a fixed base 640, and a cutter handle 660. The mounting plate 610 is fixedly connected to the top surface of the base plate 10. The electric cylinder 620 is fixedly mounted on the top surface of the mounting plate 610. The first cutter holder 630 is connected to the output shaft of the electric cylinder 620. The fixed base 640 is fixedly connected to the top surface of the electric cylinder 620, and a second cutter holder 650 is connected to the top surface of the fixed base 640.

[0045] One end of the handle 660 is hinged to the top of the first cutter holder 630, and the middle part of the handle 660 is hinged to the top of the second cutter holder 650. The other end of the handle 660 has a slot, and a cutting blade 670 for cutting the wire harness 920 is connected inside the slot. The cutting component 60 also includes a blade limiting seat 680 and a protective cover 690. The blade limiting seat 680 is screwed to the top surface of the base plate 10 and is located directly below the cutting blade 670. A limiting groove is also provided inside the blade limiting seat 680 corresponding to the falling position of the cutting blade 670. The protective cover 690 is disposed outside the electric cylinder 620 and the blade limiting seat 680.

[0046] As explained, the mounting plate 610 is fixedly connected to the top surface of the base plate 10, and the electric cylinder 620 is fixedly installed on the top surface of the mounting plate 610. It mainly achieves the up-and-down reciprocating mechanical action through electric drive. The first cutter holder 630 is connected to the output shaft of the electric cylinder 620, and the second cutter holder 650 is fixedly connected to the top surface of the fixed seat 640 set on the top surface of the electric cylinder 620. The electric cylinder 620 drives the first cutter holder 630 through its output shaft to generate sufficient force to complete the cutting task. The cooperation between the first cutter holder 630, the second cutter holder 650 and the cutter handle 660 adopts the working principle of a seesaw. The output shaft of the electric cylinder 620 drives the first cutter holder 630 to move upward. The first cutter holder 630 lifts one end of the cutter handle 660 connected to it, thereby causing the cutter handle 660, on the other end of which is equipped with the cutting blade 670, to move downward, thus completing the cutting action.

[0047] Specifically, the second tool holder 650 is fixedly connected to the top surface of the electric cylinder 620. One end of the tool holder 660 is hinged to the top of the first tool holder 630, and the other end is hinged to the top of the second tool holder 650. Through the hinge, the tool holder 660 can swing or rotate within a certain range to flexibly complete the cutting action. The blade limiting seat 680 is installed on the top surface of the base plate 10 and is located directly below the cutting blade 670. A limiting groove is formed inside the blade limiting seat 680, corresponding to the falling position of the cutting blade 670. Through the limitation of the groove, the blade can be prevented from accidentally displacing during the cutting process, thereby ensuring cutting accuracy. The protective cover 690 is installed on the outside of the electric cylinder 620 and the blade limiting seat 680 to provide protection.

[0048] Refer to the attached diagrams in the instruction manual. Figures 1-5 As shown, the base plate 10 is also provided with support seats 80, and at least four support seats 80 are provided and are respectively fixedly installed at the four corners of the bottom surface of the base plate 10.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
