DETAILED DESCRIPTION

[0021] Example

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] A wire harness cutting device, wherein a hinged platform 2 is fixedly connected to the surface of a base 1, a mounting shaft 3 is inserted above the hinged platform 2, a winding roller 4 is fixedly connected to the surface of the mounting shaft 3, and the winding roller 4 is used to wind and reel the wire harness, so as to facilitate length control of the wire harness when cutting. A traction mechanism 5 is installed on the surface of the base 1 on one side of the winding roller 4, and a fixing mechanism 6 is fixedly connected to the surface of the traction mechanism 5. After the wire harness is wound and fixed on the surface of the winding roller 4, by fixing one end of the wire harness to the fixing mechanism 6, the traction mechanism 5 is further turned on to operate and drive the fixing mechanism 6 to move, so that the fixing mechanism 6 pulls the wire harness. A cutting mechanism 7 is fixedly connected to the surface of the base 1, and the cutting mechanism 7 is located between the winding roller 4 and the fixing mechanism 6. Further, after the fixing mechanism 6 pulls the wire harness to a specified length, the cutting mechanism 7 is operated to cut the wire harness to a specified length, thereby achieving accurate cutting of the wire harness. The surface of the base 1 is fixedly connected with a cut length control mechanism 8 and a scale 9. The scale 9 is located below the cut length control mechanism 8, and the cut length control mechanism 8 is located on one side of the traction mechanism 5. When the traction mechanism 5 drives the fixing mechanism 6 to move, the specified cut length of the wire harness can be set through the cut length control mechanism 8 and the scale 9. Further, when the fixing mechanism 6 pulls the wire harness to the specified length, the cut length control mechanism 8 automatically controls the winding roller 4 to pause the lengthening of the wire harness, thereby realizing automatic cutoff of the wire harness at the precise length.

[0024] The traction mechanism 5 includes two sets of mounting seats 501 mounted on the surface of the base 1. Two sets of position-limiting support rods 502 are inserted between the two sets of mounting seats 501. A slide 503 is mounted on the surface of the two sets of position-limiting support rods 502. The fixing mechanism 6 is mounted on the surface of the slide 503. A screw 504 is inserted between the two sets of mounting seats 501 and is adapted to be mounted inside the slide 503. A motor 505 is fixedly connected to the surface of the mounting seats 501. The output shaft of the motor 505 is in driving connection with the screw 504. When the motor 505 is turned on, it drives the slide 503 to slide linearly on the surface of the screw 504, further adjusting the spacing between the fixing mechanism 6 and the winding roller 4, so that the fixing mechanism 6 can pull the length of the wire harness.

[0025] The surface of the slide 503 is fixedly connected to a mounting bracket A506. The surface of the mounting bracket A506 is provided with a threaded hole, and a threaded rod A507 is inserted into the threaded hole. The upper end surface of the threaded rod A507 is sleeved and connected to the lifting platform 508. The fixing mechanism 6 includes an M-type platform 601 mounted on the surface of the lifting platform 508. The upper surface of the M-type platform 601 is provided with a slot 602, and a clamping plate 603 is inserted into the interior of the slot 602. The upper end surface of the clamping plate 603 is fixedly connected to a T-shaped rod 604. At the same time, the upper end surface of the M-type platform 601 is provided with a threaded hole. The upper end surface of the T-shaped rod 604 is provided with two sets of through holes, and fixing bolts 605 are inserted into each of the two sets of through holes. The lower ends of the two sets of fixing bolts 605 are inserted into the two sets of threaded holes on the surface of the M-type platform 601. Furthermore, after placing wire harnesses of different radii on the surface of the M stage 601, the insertion depth of the clamp 603 in the slot 602 can be controlled by tightening the fixing bolt 605 in the threaded hole on the surface of the M stage 601, thereby further enabling the M stage 601 and the slot 602 to clamp and fix wire harnesses of different radii, thereby improving the applicability of the device. Furthermore, after the fixing mechanism 6 clamps and fixes wire harnesses of different radii, the height of the lifting platform 508 can be adjusted by rotating the threaded rod A507 on the mounting frame A506, thereby further achieving the height of the fixing mechanism 6, so that the wire harness clamped and fixed on the fixing mechanism 6 always remains flush with the winding roller 4. The surface wire harness is greatly bent during the pulling process, resulting in an uneven cut surface during the cutting process.

[0026] The cutting mechanism 7 includes a mounting frame B701 connected to the surface of the base 1. The mounting frame B701 has a threaded hole on its surface, into which a threaded rod B702 is inserted. A support platform 703 is sleeved on the upper surface of the threaded rod B702. After the fixing mechanism 6 clamps and secures wire bundles of varying radius and adjusts their height, the threaded rod B702 rotates to adjust the height of the support platform 703, bringing the upper surface of the support platform 703 into contact with the wire bundle. This provides effective support during cutting, allowing for quick cutting and maintaining a smooth cut surface. A top frame 704 is fixedly connected to the surface of the mounting frame B701. An electric telescopic rod 705 is fixedly connected to the lower surface of the top frame 704. A cutting blade 706 is fixedly connected to the lower end of the piston rod of the electric telescopic rod 705. When the electric telescopic rod 705 is activated, it drives the cutting blade 706 downward, pressing the wire bundle against the support platform 703 and quickly cutting the wire bundle. Two sets of fixing rods 707 are fixedly connected to the surface of the mounting frame B701. Both sets of fixing rods 707 are hingedly mounted with rollers 708 on their surfaces. The two sets of rollers 708 are symmetrically distributed. Furthermore, when the fixing mechanism 6 pulls the wire harness, the wire harness is positioned between the two sets of rollers 708, preventing the wire harness from significantly bending left and right during the pulling process, which would result in an uneven cross-section.

[0027] The truncation length control mechanism 8 includes a fixed table A801 ​​and a fixed table B802 installed on the surface of the base 1. The surface of the fixed table A801 ​​is fixedly connected to a fixed tube 803, which is set in a "T" shape and is located on one side of the hinged table 2. An insertion rod A804 is inserted into the vertical end of the fixed tube 803, and a piston block A805 is fixedly connected to the lower end surface of the insertion rod A804. The piston block A805 is inserted into the interior of the fixed tube 803. The upper end surface of the insertion rod A804 is fixedly connected to a pressure block 812, which is located at the lower end of the mounting shaft 3, and the pressure block 812 is set in a "V" shape and has a texture on the surface. The horizontal end surface of the fixed tube 803 is sheathed with a movable sleeve 807, which is also configured as a "T" structure. A blocking rod 806 is fixedly connected to the surface of the fixed platform B802 and inserted into the horizontal end of the movable sleeve 807. A plug rod B808 is inserted into the vertical end of the movable sleeve 807. A trapezoidal block 809 is fixedly connected to the upper end surface of the plug rod B808, and a piston block B810 is fixedly connected to the lower end surface of the plug rod B808. The piston block B810 is inserted into the interior of the movable sleeve 807. A spring 811 is sheathed on the surface of the plug rod B808, one end of which is connected to the inner wall of the movable sleeve 807, and the other end of the spring 811 is connected to the surface of the piston block B810. A trigger rod 509 is fixedly connected to the surface of the mounting bracket A506. When the traction mechanism 5 pulls the fixing mechanism 6, the trigger rod 509 is controlled to slide horizontally. The side surface of the trapezoidal block 809 facing the trigger rod 509 is configured as an inclined surface, so that the trigger rod 509 contacts the surface of the trapezoidal block 809 during the sliding process, pushing the trapezoidal block 809 downward, further controlling the insertion rod B808 to insert into the movable sleeve 807 and squeeze the piston block B810. The interior of the movable sleeve 807 is filled with compressed air, further causing the insertion rod B808 to squeeze the compressed air inside the movable sleeve 807. One end of the movable sleeve 807 is connected to the interior of the fixed tube 803, and the other end of the movable sleeve 807 is blocked by the blocking rod 806, so that the compressed air in the movable sleeve 807 pushes the piston block A805 to slide within the fixed tube 803, further controlling the insertion rod A804 to push the pressure block 812 to slide upward and contact the surface of the articulated platform 2. The pressure block 812 applies pressure to the articulated platform 2, so that the articulated platform 2 cannot be pulled and rotated, and the winding roller 4 further prevents the lengthening of the wire harness. After the fixing mechanism 6 pulls the wire harness to the specified length, the cutting mechanism 7 operates to cut the wire harness to the specified length, thereby achieving accurate cutting of the wire harness.

[0028] By sliding the movable sleeve 807 on the surfaces of the fixed tube 803 and the blocking rod 806, and controlling the vertical end of the movable sleeve 807 to slide to a specified length above the scale 9, the cut length of the wire harness can be precisely controlled. Simultaneously, as the movable sleeve 807 slides, the volume between the insertion rod A804 and the movable sleeve 807 increases, but the blocking rod 806 simultaneously reduces the volume inside the movable sleeve 807, further maintaining the volume inside the movable sleeve 807 constant. This, in turn, maintains the pressure of the compressed air inside the movable sleeve 807 on the piston block A805, allowing the pressure block 812 to effectively limit the articulation platform 2.
