Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a positioning structure for CNC machining of precision wire harness support components. Background Technology

[0002] Precision wire harnesses are high-precision, high-reliability electronic components widely used in automotive, aviation, aerospace, medical, and communications industries. A precision wire harness consists of multiple wires or cables arranged in a specific order and connected by specialized connectors to transmit power, signals, and data. It typically comprises contact terminals, wires and cables, insulators, and a metal housing, and is formed into a circuit assembly through molding or bundling. Precision wire harnesses are characterized by high precision and high reliability, requiring strict process and quality control in their design and manufacturing. With technological advancements, precision wire harnesses are increasingly trending towards lightweight materials, automated production, and high-voltage applications in new energy sources.

[0003] Existing positioning equipment cannot adjust the distance between two sets of wire harnesses after fixing them. The positioning and fixing of wire harnesses has certain limitations, and different positioning equipment is required for different wire harnesses. The applicable range of positioning equipment is relatively small.

[0004] To address this issue, we propose a positioning structure for CNC machining of precision wire harness support components. Utility Model Content

[0005] The purpose of this invention is to provide a positioning structure for CNC machining of precision wire harness support components, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A positioning structure for CNC machining of a precision wire harness support component, comprising,

[0008] The base plate has a U-shaped plate fixedly installed at each of the four upper corners, and a limit block is provided on the outside of the U-shaped plate accordingly;

[0009] A fixing mechanism is used to fix the wire harness. The fixing mechanism includes a slider that is slidably connected to the inner wall of a U-shaped plate. A threaded rod is rotatably connected inside the U-shaped plate. The threaded rod is threaded through the slider. The upper ends of the four threaded rods are rotatably connected through the U-shaped plate and are connected by a first transmission mechanism. A first motor is fixedly connected to the upper end of one of the U-shaped plates. The drive shaft of the first motor is coaxially fixedly connected to the threaded rod. A connecting rod is fixedly connected between two sliders on the same side. The connecting rod is slidably connected through two limiting blocks.

[0010] An adjustment mechanism is used to adjust the distance between the fixed wire harnesses. The adjustment mechanism includes two bidirectional threaded rods, which are threaded through four limiting blocks respectively. The two ends of the two bidirectional threaded rods are rotatably connected to four sliders respectively. One end of each of the two bidirectional threaded rods rotatably passes through a slider and is connected to it through a second transmission mechanism. A second motor is fixedly connected to the side wall of one of the sliders. The drive shaft of the second motor is coaxially fixedly connected to the bidirectional threaded rod.

[0011] Furthermore, the first transmission mechanism includes four first pulleys, which are coaxially and fixedly connected to four threaded rods, and are connected to each other by a synchronous belt drive.

[0012] Furthermore, the second transmission mechanism includes two second pulleys, which are coaxially and fixedly connected to two threaded rods respectively, and are connected to each other by a synchronous belt drive.

[0013] Furthermore, both limiting blocks located outside the same bidirectional threaded rod are provided with threaded holes that match the bidirectional threaded rod, and the threads in the two threaded holes have opposite directions.

[0014] Furthermore, the lower end of the limiting block is arc-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0016] 1. By setting up a fixing mechanism, the first motor drives four threaded rods to rotate, the four threaded rods drive four sliders to rise and fall, and the four sliders drive four limit blocks to rise and fall synchronously through four connecting rods, which can fix wire harnesses of different sizes and has a wide range of applications for positioning and fixing wire harnesses.

[0017] 2. By setting an adjustment mechanism, the second motor drives two bidirectional threaded rods to rotate, and the two bidirectional threaded rods drive four limit blocks to move relative to each other until the appropriate position is reached. This allows the distance between the two fixed precision wire harnesses to be adjusted. After the position is fixed, the position of the precision wire harnesses can also be adjusted.

[0018] This invention has a wide range of applications for positioning and fixing precision wire harnesses, and the position of the precision wire harness can also be adjusted after positioning. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0025] The base plate 1 has a U-shaped plate 2 fixedly installed at each of the four corners of the upper end of the base plate 1. A limit block 3 is set on the outside of the U-shaped plate 2. It should be noted that the lower end of the limit block 3 is arc-shaped.

[0026] To fix the two precision wire harnesses, a fixing mechanism 4 is provided for fixing the wire harnesses. The fixing mechanism 4 includes a slider 5 that is slidably connected to the inner wall of the molded plate 2. A threaded rod 6 is rotatably connected inside the molded plate 2. The threaded rod 6 is threaded through the slider 5. The upper ends of the four threaded rods 6 are rotatably connected through the molded plate 2 and are connected by a first transmission mechanism 7. Specifically, the first transmission mechanism 7 includes four first pulleys 14. The four first pulleys 14 are coaxially fixedly connected to the four threaded rods 6 respectively. The four first pulleys 14 are connected by a synchronous belt. The upper end of one molded plate 2 is fixedly connected to a first motor 8. The drive shaft of the first motor 8 is coaxially fixedly connected to the threaded rod 6. A connecting rod 9 is fixedly connected between the two sliders 5 on the same side. The connecting rod 9 is slidably connected through the two limiting blocks 3.

[0027] Through the above technical features, the first motor 8 drives four threaded rods 6 to rotate, the four threaded rods 6 drive four sliders 5 to rise and fall, and the four sliders 5 drive four limit blocks 3 to rise and fall synchronously through four connecting rods 9, so that wire harnesses of different sizes can be fixed.

[0028] After the precision wire harness is fixed, the distance between the precision wire harnesses needs to be adjusted. Therefore, an adjustment mechanism 10 is set up to adjust the distance between the fixed wire harnesses. The adjustment mechanism 10 includes two bidirectional threaded rods 11. The two bidirectional threaded rods 11 are respectively threaded through four limiting blocks 3. The two ends of the two bidirectional threaded rods 11 are respectively rotatably connected to four sliders 5. It should be noted that the two limiting blocks 3 located outside the same bidirectional threaded rod 11 are provided with threaded holes that match the bidirectional threaded rod 11. The threads in the two threaded holes have opposite directions. One end of the two bidirectional threaded rods 11 rotatably passes through the sliders 5 and is connected by a second transmission mechanism 12. It is worth mentioning that the second transmission mechanism 12 includes two second pulleys 15. The two second pulleys 15 are respectively coaxially fixedly connected to the two threaded rods 6. The two second pulleys 15 are connected by a synchronous belt. A second motor 13 is fixedly connected to the side wall of one of the sliders 5. The drive shaft of the second motor 13 is coaxially fixedly connected to the bidirectional threaded rod 11.

[0029] By setting the row number technical features, the second motor 13 drives the two bidirectional threaded rods 11 to rotate, and the two bidirectional threaded rods 11 drive the four limit blocks 3 to move relative to each other until they reach the appropriate position, so that the distance between the two fixed precision wire harnesses can be adjusted.

[0030] Working principle:

[0031] 1) Positioning and fixing of precision wire harnesses: The first motor 8 drives four threaded rods 6 to rotate, the four threaded rods 6 drive four sliders 5 to rise and fall, and the four sliders 5 drive four limit blocks 3 to rise and fall synchronously through four connecting rods 9, so that wire harnesses of different sizes can be fixed.

[0032] 2) Adjusting the position of the fixed precision wire harness: The second motor 13 drives the two bidirectional threaded rods 11 to rotate, and the two bidirectional threaded rods 11 drive the four limit blocks 3 to move relative to each other until the appropriate position is reached, so that the distance between the two fixed precision wire harnesses can be adjusted.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
