[0015] 1. This utility model provides a cutting device for directional wire harness production. It employs a base, a limiting plate, a scale plate, a fixing component, a moving positioning mechanism, a mounting plate, a cutting mechanism, a connecting plate, a moving block, a first stepper motor, a first lead screw, a control panel, and a combination of a second stepper motor and a second lead screw. The fixing component secures the surface of the wire harness. The wire harness passes through the cutting mechanism, and the output shaft of the second stepper motor drives the second lead screw to rotate, causing the moving positioning mechanism to slide along the scale plate, clamping and positioning the tail end of the wire harness. Finally, the first stepper motor drives the first lead screw to rotate, causing the moving block to move the cutting mechanism to the cutting position via the mounting plate.

During the cutting process, a hydraulic cylinder drives the cutting plate downwards, causing the pressing and positioning components on both sides to press and position the two ends of the wire harness. As the cutting plate continues to move downwards, the cutting blades cut the wire harness. This solves the problem of the wire harness easily shifting and causing cutting errors when the two ends cannot be pressed down during cutting. It achieves the beneficial effect of pressing and cutting the two ends of the wire harness, preventing shifting, and ensuring cutting accuracy. Attached Figure Description

[0026] like Figure 2As shown, this utility model provides a cutting device for directional wire harness production: the fixing component 4 includes a T-shaped base 41, two concave fixed plates 42, two movable plates 43, a screw 44, a limiting rod 45, a nut 46, and two anti-slip pads 47. The outer surfaces of the two concave fixed plates 42 are mirror images of each other on the upper and lower sides of the top of the horizontal surface of the T-shaped base 41. The bottom of the lower concave fixed plate 42 is fixedly connected to the top of the horizontal surface of the T-shaped base 41.

The outer wall of the scale plate 3 is slidably connected to the inside of the moving groove 520, which limits the movement trajectory of the fixed plate 52.

[0028] like Figure 4 As shown, this utility model provides a technical solution for a cutting device for directional wire harness production: the cutting mechanism 7 includes a hydraulic cylinder 71, an L-shaped support plate 72, a cutting plate 73, cutting shears 74, a slider 75, and a pointer 76. The output end of the hydraulic cylinder 71 extends through to the bottom of the mounting plate 6 and is fixedly connected to the top of the cutting plate 73. The top of the cutting shears 74 is fixedly connected to the bottom of the cutting plate 73. A groove 720 is provided on the vertical inner wall of the L-shaped support plate 72. One end of the slider 75 is fixedly connected to the left end of the cutting plate 73, and the outer wall of the slider 75 is slidably connected to the inner wall of the groove 720. The cutting plate 73 slides along the slide groove 720 via the slider 75, which improves the stability of the cutting plate 73's movement. The top of the horizontal surface of the L-shaped support plate 72 has a cutting groove 721 that is perpendicular to the cutting scissors 74. The bottom of the cutting scissors 74 cuts into the cutting groove 721 to prevent the cutting scissors 74 from damaging the surface of the L-shaped support plate 72. One end of the pointer 76 is fixedly connected to the right end of the horizontal surface of the L-shaped support plate 72, and the top of the vertical direction of the L-shaped support plate 72 is fixedly connected to the bottom of the mounting plate 6. Two pressing and positioning components 8 are respectively set on the middle side of the front and rear ends of the cutting plate 73.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a cutting device for directional wire harness production: the pressing and positioning component 8 includes a clamping plate 81, a movable rod 82, a high-strength spring 83, a pressure plate 84, and several rubber strips 85. One end of the clamping plate 81 is fixedly connected to the outer wall of the cutting plate 73. The outer surface of the movable rod 82 passes through the upper and lower ends of the clamping plate 81 and is slidably connected between them. The bottom of the movable rod 82 is fixedly connected to the top of the pressure plate 84. The inner part of the high-strength spring 83 is sleeved on the outer wall of the movable rod 82. The upper end of the high-strength spring 83 is fixedly connected to the lower surface of the clamping plate 81, and the lower end of the high-strength spring 83 is fixedly connected to the upper surface of the rubber strips 85. The high-strength spring 83 is provided to fix the tops of the several rubber strips 85 in an equidistant array to the lower end of the pressure plate 84. The rubber strips 85 are pressed tightly against the surface of the wire harness, increasing the stability of the wire harness cutting and preventing displacement.

[0030] The working principle of this type of cutting device for directional wire harness production will be explained in detail below.

[0031] like Figure 1-5As shown, when using this device to cut directional wire harnesses, first, connect the device to an external power source. First, move the upper concave plate 42 upwards along the screw 44 and limit rod 45 through the insertion hole 430. Place the part of the wire harness to be cut on the lower concave plate 42. The upper concave plate 42 presses against the upper surface of the wire harness. Then, rotate the nut 46 to press it against the upper surface of the movable plate 43, thus pressing and fixing the end of the wire harness. Next, pass the wire harness along the upper surface of the L-shaped support plate 72 and place it on the fixed plate 52. Open the electric telescopic rod 54 to begin operation. The output ends of the electric telescopic rods 54 on both sides drive the two clamping plates 55 to move inwards, causing the rollers 56 on both sides to clamp and adhere to the surface of the wire harness. Then, control the output shaft of the stepper motor 15 to drive the lead screw 16 to rotate, causing the movable block... 51 drives the fixed plate 52 to move backward along the surface of the scale plate 3. According to the length range of the wire harness cutting, the two rollers 56 clamp and fix the tail end of the wire harness. Then, according to the cutting length, the stepper motor 12 is driven to work, so that the output shaft of the stepper motor 12 drives the lead screw 13 to rotate. The moving blocks 10 on both sides drive the mounting plate 6 to move forward or backward through the connecting plate 9. Combined with the pointer 76 pointing to the specific cutting length on the scale plate 3, the stepper motor 12 stops working. Then, the hydraulic cylinder 71 is operated. The output end of the hydraulic cylinder 71 drives the cutting plate 73 to move downward, which drives the pressure plates 84 on both sides to press the two ends of the wire harness. As the cutting plate 73 continues to move downward, the high-strength spring 83 is squeezed inward and deformed. The movable rod 82 extends upward along the clamping plate 81 until the cutting scissors 74 completes the cutting of the wire harness.

[0032] The specific types and structures of the electric telescopic poles, hydraulic cylinders, and stepper motors used above are all existing products, as are the specific circuit connection structures and control relationships, which are all existing technologies and will not be elaborated further here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
