Description

Technical Field

[0001] This utility model relates to the field of wire cutting device technology, specifically a high-precision wire harness wire cutting device. Background Technology

[0002] Wire harnesses are used to facilitate installation and maintenance, ensuring that electrical equipment can operate under the harshest conditions. They organize wires of different specifications and colors used in various electrical devices into a single bundle, which is then bound together with insulating material. This ensures both integrity and reliability. Currently, during wire harness manufacturing, multiple cables within the same bundle are typically cut to different lengths as needed.

[0003] For example, patent application number 202121752233.9 discloses a high-precision wire harness cutting device. This utility model can straighten the wire harness during cutting, improve the cutting accuracy, and can complete the cutting of multiple cables of different lengths at one time, greatly improving cutting efficiency and cutting stability. However, the structure that fixes the wire harness on both sides of the wire harness cutting device cannot be moved or adjusted, i.e., it is in a fixed state. Excessively long wire harnesses can naturally pass through the fixing mechanism on both sides and be fixed in the middle for cutting, but excessively short wire harnesses cannot be effectively tightened and fixed. In use, it is difficult to meet the fixing needs of various different wire harnesses, and there are certain limitations.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a high-precision wire harness cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision wire harness cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision wire harness cutting device, comprising a base, a groove formed in the middle of the upper surface of the base, a bidirectional lead screw rotatably connected to the inner surface of the groove, adjusting seats threadedly connected to the left and right sides of the surface of the bidirectional lead screw, a movable plate fixedly connected to the upper surface of the adjusting seats, a side plate fixedly connected to the rear side of the base surface, a guide groove formed on the upper surface of the side plate, a screw rotatably connected to the inner surface of the guide groove, and a bracket threadedly connected to the surface of the screw.

[0007] Preferably, the surface of the adjusting seat is slidably fitted to the inner surface of the groove, and the bottom surface of the bracket is slidably fitted to the inner surface of the guide groove.

[0008] Preferably, a drive motor is fixedly connected to the right side of the base, and the output end of the drive motor passes through the base and is connected to a bidirectional lead screw. A rotary motor is fixedly connected to the right side of the side plate, and the output end of the rotary motor passes through the side plate and is connected to a screw.

[0009] Preferably, a cylinder is fixedly connected to the upper end of the bracket, and a cutting blade is fixedly connected to the bottom end of the cylinder through the bracket.

[0010] Preferably, a support frame is fixedly connected to the upper surface of the base, and a through cavity is opened on the surface of the movable plate, and the movable plate is slidably sleeved on the surface of the support frame through the through cavity.

[0011] Preferably, the surface of the movable plate is provided with placement grooves evenly distributed on the upper side of the cavity, and a pressure plate is provided on the upper side of the inner surface of the placement groove.

[0012] Preferably, a threaded handle is rotatably connected to the upper surface of the pressure plate, and the upper end of the threaded handle penetrates the moving plate, with the penetration portion threadedly connected to the moving plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of grooves, bidirectional lead screws, adjusting seats, side plates, guide grooves, screws, brackets, and moving plates, allows the bidirectional lead screw to rotate. With the groove limiting the adjusting seats, the adjusting seats do not rotate synchronously with the lead screw, but are only subjected to threaded force, causing the two adjusting seats to move in opposite directions. This, in turn, moves the two moving plates, adjusting the distance between them. This allows the moving plates to fix and tighten wire harnesses of different lengths. Simultaneously, with the screw rotating and the guide groove limiting the bracket, the bracket is subjected to the threaded force of the screw rotation and moves left and right. This causes the bracket to move the cutting blade left and right, cutting the wire harness at different positions. The entire device can be flexibly adjusted according to the wire harness length and cutting point, allowing it to adapt to the tightening and cutting of wire harnesses of different lengths. After tightening, the wire harness will not bend or become excessively long, thus improving cutting accuracy. No manual adjustment of the wire harness is required, greatly enhancing the flexibility and practicality of the device.

[0015] 2. This utility model, through the arrangement of a support frame, a through cavity, a placement groove, a pressure plate, and a threaded lever, allows the two ends of the wire harness to be inserted into the placement groove. Rotating the threaded lever pushes the pressure plate downwards, enabling the pressure plate to firmly press and fix the two ends of the wire harness within the placement groove. This prevents the wire harness from falling off when the moving plate adjusts and tightens the wire harness, ensuring stable tension. The through cavity allows the moving plate to move freely left and right on the surface of the support frame. The support frame raises the overall support height of the base for the wire harness, reducing the redundant space under the wire harness. This allows the cutting blade to apply force more effectively for cutting. The reduced redundant space prevents the wire harness from contacting the pressure of the cutting blade, which could cause the wire harness to bend and become uncut. It also prevents the wire harness from bending and slipping at the cutting point, resulting in inaccurate cutting. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3As shown, a high-precision wire harness cutting device includes a base 1. A groove 2 is formed in the middle of the upper surface of the base 1. A bidirectional lead screw 3 is rotatably connected to the inner surface of the groove 2. Adjustment seats 5 are threadedly connected to both sides of the surface of the bidirectional lead screw 3. A movable plate 14 is fixedly connected to the upper surface of the adjustment seat 5. A side plate 6 is fixedly connected to the rear side of the surface of the base 1. A guide groove 7 is formed in the upper surface of the side plate 6. A screw 8 is rotatably connected to the inner surface of the guide groove 7. A bracket 10 is threadedly connected to the surface of the screw 8. The surface of the adjustment seat 5 slides and fits against the inner surface of the groove 2, and the bottom surface of the bracket 10 slides and fits against the inner surface of the guide groove 7.

[0022] By adopting the above technical solution, the bidirectional lead screw 3 rotates, and under the limitation of the groove 2 on the adjusting seat 5, the adjusting seat 5 will not rotate synchronously with the bidirectional lead screw 3, but will only be subjected to the thread force, so that the two adjusting seats 5 on both sides move in opposite directions or in the opposite direction.

[0023] The movement of the adjusting seat 5 will drive the movement of the two moving plates 14 on both sides to adjust the distance between the two moving plates 14 so that the moving plates 14 can fix and tighten wire harnesses of different lengths.

[0024] When the screw 8 rotates, the bracket 10 is limited by the guide groove 7. The bracket 10 will move left and right due to the thread force of the screw 8, which will cause the bracket 10 to drive the cutting blade 12 to move left and right to cut the wire harness at different positions.

[0025] Furthermore, a drive motor 4 is fixedly connected to the right side of the base 1, and the output end of the drive motor 4 passes through the base 1 and is connected to the bidirectional lead screw 3. A rotary motor 9 is fixedly connected to the right side of the side plate 6, and the output end of the rotary motor 9 passes through the side plate 6 and is connected to the screw 8.

[0026] By adopting the above technical solution, the drive motor 4 and the rotary motor 9 provide rotational power to the bidirectional lead screw 3 and the screw 8, respectively.

[0027] Furthermore, a cylinder 11 is fixedly connected to the upper end of the bracket 10, and a cutting blade 12 is fixedly connected to the bottom end of the cylinder 11 through the bracket 10.

[0028] By adopting the above technical solution, the cylinder 11 can push the cutting blade 12 downward to cut the wire harness.

[0029] Furthermore, a support frame 13 is fixedly connected to the upper surface of the base 1, and a through cavity 15 is opened on the surface of the movable plate 14, and the movable plate 14 is slidably sleeved on the surface of the support frame 13 through the through cavity 15.

[0030] By adopting the above technical solution, the cavity 15 allows the movable plate 14 to move freely left and right on the surface of the support frame 13;

[0031] The support frame 13 raises the support height of the entire base 1 for the wire harness, reducing the space redundancy on the lower side of the wire harness, thereby allowing the cutting blade 12 to apply force for cutting better. The reduced space redundancy avoids the wire harness from contacting the pressure of the cutting blade 12, which could cause the wire harness to bend and become uncut. It also avoids the wire harness bending, which could cause the cutting point to slip and result in inaccurate cutting.

[0032] Furthermore, the surface of the movable plate 14 is provided with evenly distributed placement grooves 16 on the upper side of the cavity 15, and a pressure plate 17 is provided on the upper side of the inner surface of the placement groove 16; a threaded lever 18 is rotatably connected to the upper surface of the pressure plate 17, and the upper end of the threaded lever 18 passes through the movable plate 14, and the passing part is threadedly connected to the movable plate 14.

[0033] By adopting the above technical solution, the two ends of the wire harness are inserted into the placement groove 16. Rotating the threaded lever 18 can push the pressure plate 17 downward, so that the pressure plate 17 can firmly press down and fix the two ends of the wire harness in the placement groove 16. This prevents the wire harness from falling off when the moving plate 14 adjusts and tightens the wire harness, and ensures the stability of the wire harness tension.

[0034] Working principle: When using this high-precision wire harness cutting device, firstly, both ends of the wire harness are inserted into the placement groove 16. Rotating the threaded lever 18 pushes the pressure plate 17 downward, allowing the pressure plate 17 to firmly press and fix the two ends of the wire harness within the placement groove 16. Then, the drive motor 4 rotates the bidirectional lead screw 3. Under the limitation of the groove 2 on the adjusting seat 5, the adjusting seat 5 will not rotate synchronously with the bidirectional lead screw 3, but will only be subjected to the thread force, causing the two adjusting seats 5 to move in opposite directions, thereby driving the two moving plates 14 to move. Adjusting the distance between the two moving plates 14 allows the moving plates 14 to pull and fix and tighten wire harnesses of different lengths. After the wire harness is tightened, the screw 8 rotates, and the guide groove 7 presses against the bracket 1. When the limit is 0, the bracket 10 will move left and right due to the thread force of the screw 8 rotating, thereby causing the bracket 10 to drive the cutting blade 12 to move left and right. The cutting blade 12 is adjusted to the part of the wire harness that needs to be cut, and the cylinder 11 can push the cutting blade 12 down to cut the wire harness. The support frame 13 raises the support height of the entire base 1 for the wire harness, reducing the redundancy of the space under the wire harness, so that the cutting blade 12 can better apply force to cut. The reduced space redundancy avoids the pressure of the wire harness contacting the cutting blade 12, which may cause the wire harness to bend and become uncut. It also avoids the wire harness bending and causing the cutting point to slip, resulting in inaccurate cutting. This is the working principle of this high-precision wire harness cutting device.
