A cutting device for wire harness processing

Abstract

This utility model relates to the field of wire harness processing technology and discloses a cutting device for wire harness processing, including a mounting table. A limiting groove is formed on the upper surface of the mounting table, and a motor is fixedly connected to the upper surface of the mounting table. This utility model drives a screw to rotate through a motor, and the screw is connected to a telescopic tube by a thread, thereby realizing the limiting linear movement of the tail clamping plate. This stretches the wire harness and keeps it in a taut and straight state, effectively avoiding cutting errors caused by slack or sagging of the wire harness during the cutting process, significantly improving cutting accuracy and processing quality. At the same time, the head clamping plate and the tail clamping plate, in conjunction with a bidirectional screw and a handle, can quickly and firmly clamp the head and tail ends of the wire harness. This not only makes operation convenient but also ensures that the wire harness remains stable and fixed during processing, avoiding wire harness displacement or damage due to loose clamping, further improving processing efficiency and reliability.

Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a cutting device for wire harness processing. Background Technology

[0002] Wire harness processing is an indispensable and important part of modern electronics manufacturing, automobile manufacturing, communication equipment and other fields. As a key component connecting various electronic components and equipment, the processing quality of wire harnesses directly affects the stability and reliability of the entire system. Wire harness processing mainly includes multiple processes such as cutting, stripping, crimping and assembly. Among them, cutting is the first step in wire harness processing. The cutting accuracy directly determines the smooth progress of subsequent processes and the quality of the final product.

[0003] In traditional wire harness processing, cutting devices can only achieve simple fixation of the wire harness, and cannot effectively solve the cutting error problem caused by slack or sagging of the wire harness during the cutting process. Traditional devices are usually equipped with clamping mechanisms to fix the two ends of the wire harness. However, in actual operation, the wire harness needs to be manually stretched to a taut state before cutting and then fixed. This process is not only time-consuming and labor-intensive, but also difficult to guarantee the consistency of the stretching force and effect each time due to the instability of manual operation. This may cause the wire harness to slack or sag during the cutting process, thus affecting the cutting accuracy and processing quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cutting device for wire harness processing.

[0005] This utility model is achieved using the following technical solution: a cutting device for wire harness processing, comprising a mounting platform, a limiting groove being formed on the upper surface of the mounting platform, a motor being fixedly connected to the upper surface of the mounting platform, a lead screw being fixedly connected to the output end of the motor, a connecting sleeve being threadedly connected to the surface of the lead screw, a cutting frame being fixedly connected to the surface of the connecting sleeve, a cylinder being fixedly connected to the surface of the cutting frame, a cutting blade being fixedly connected to the surface of the cylinder, a tensioning mechanism being provided on the upper surface of the mounting platform, a head clamping plate being fixedly connected to the upper surface of the mounting platform, head clamping blocks being slidably connected to both sides of the head clamping plate, a bidirectional lead screw being threadedly connected to the inside of the head clamping block, and a handle being fixedly connected to the surface of the bidirectional lead screw.

[0006] The stretching mechanism includes a second limiting groove, a tail clamping plate is slidably connected inside the second limiting groove, tail clamping blocks are slidably connected to both sides of the tail clamping plate, a double-acting screw is threaded inside the tail clamping block, a handle is fixedly connected to the surface of the double-acting screw, a second motor is fixedly installed inside the mounting platform, a screw is fixedly connected to the output end of the second motor, and a telescopic tube is threadedly connected to the surface of the screw.

[0007] The above technical solution enables automatic stretching and clamping of wire harnesses, effectively avoiding cutting errors caused by slack or sagging during the cutting process, significantly improving cutting accuracy and processing quality, and facilitating personnel to quickly complete the clamping, stretching and cutting operations of wire harnesses, thereby improving work efficiency.

[0008] As a further improvement to the above solution, the connecting sleeve is slidably connected inside the limiting groove.

[0009] Through the above technical solution, the sliding of the pair of connecting sleeves in the limiting groove plays a guiding and limiting role, ensuring that the movement of the cutting frame is smooth and has good straightness, and further improving the cutting accuracy and stability.

[0010] As a further improvement to the above solution, a bearing seat is rotatably connected to the surface of the lead screw, and the bearing seat is fixedly connected to the upper surface of the mounting platform.

[0011] As a further improvement to the above solution, the telescopic tube is fixedly connected to the surface of the tail clamping plate.

[0012] As a further improvement to the above solution, guide slide rods are provided on both sides of the cutting frame.

[0013] Through the above technical solution, the guide slide provides additional guidance and support for the movement of the cutting frame, effectively reducing the shaking and offset of the cutting frame during movement and improving the cutting accuracy.

[0014] As a further improvement to the above solution, both ends of the guide slide are fixedly connected to support seats.

[0015] As a further improvement to the above solution, the support base is fixedly connected to the upper surface of the mounting platform.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a second motor to drive a screw to rotate. The screw is connected to a telescopic tube via a thread, which enables the tail clamping plate to move linearly and stretch the wire harness, keeping it taut and straight. This effectively avoids cutting errors caused by slack or sagging during the cutting process, significantly improving cutting accuracy and processing quality. Simultaneously, the head and tail clamping plates, in conjunction with a bidirectional lead screw and handle, can quickly and firmly clamp both ends of the wire harness. This not only makes operation convenient but also ensures the wire harness remains stable and fixed during processing, preventing displacement or damage due to insecure clamping, further enhancing processing efficiency and reliability.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4This embodiment of a wire harness processing cutting device includes a mounting platform 1. A limit groove 2 is formed on the upper surface of the mounting platform 1. A motor 3 is fixedly connected to the upper surface of the mounting platform 1. A lead screw 4 is fixedly connected to the output end of the motor 3. A connecting sleeve 5 is threadedly connected to the surface of the lead screw 4. A cutting frame 6 is fixedly connected to the surface of the connecting sleeve 5. A cylinder 7 is fixedly connected to the surface of the cutting frame 6. A cutting blade 8 is fixedly connected to the surface of the cylinder 7. A tensioning mechanism 9 is provided on the upper surface of the mounting platform 1. A head clamping plate 10 is fixedly connected to the upper surface of the mounting platform 1. Head clamping blocks 11 are slidably connected to both sides of the head clamping plate 10. A bidirectional lead screw 12 is threadedly connected to the inside of the head clamping block 11. A handle 13 is fixedly connected to the surface of the bidirectional lead screw 12.

[0027] The tensioning mechanism 9 includes a limiting groove 901, with a tail clamping plate 902 slidably connected inside the limiting groove 901. Tail clamping blocks 903 are slidably connected to both sides of the tail clamping plate 902. A bidirectional lead screw 904 is threadedly connected inside the tail clamping block 903. A handle 905 is fixedly connected to the surface of the bidirectional lead screw 904. A motor 906 is fixedly installed inside the mounting platform 1. A screw 907 is fixedly connected to the output end of the motor 906. A telescopic tube 908 is threadedly connected to the surface of the screw 907. When the operator places the wire harness end on the surface of the head clamping plate 10, rotating the handle 13 drives the bidirectional lead screw 12 to rotate, causing the two head clamping blocks 11 to move synchronously towards the center, clamping and fixing the wire harness end. Then, the tail end of the wire harness is placed... On the surface of the tail clamping plate 902, turn the handle 905 to make the two tail clamping blocks 903 move synchronously towards the center, clamping and fixing the tail end of the wire harness. Start the motor 906, and its output end drives the screw 907 to rotate. The screw 907 is threadedly connected to the telescopic tube 908, and the telescopic tube 908 is fixed on the surface of the tail clamping plate 902. The screw 907 drives the tail clamping plate 902 to move linearly along the limiting groove 901, so that the tail clamping plate 902 moves backward, thereby stretching the wire harness and avoiding cutting errors caused by the wire harness being loose or sagging during the cutting process, thus improving the cutting accuracy. At the same time, the output end of the motor 3 drives the lead screw 4 to rotate. The lead screw 4 drives the cutting frame 6 to move along the limiting groove 2 through the connecting sleeve 5. The cylinder 7 pushes the cutting blade 8 to perform the cutting operation.

[0028] The connecting sleeve 5 is slidably connected to the inside of the limiting groove 2, so that the cutting frame 6 can move stably in a straight line along the limiting groove 2 during the movement, ensuring the accurate cutting trajectory of the cutting blade 8.

[0029] The lead screw 4 is rotatably connected to a bearing seat, which is fixedly connected to the upper surface of the mounting platform 1.

[0030] The telescopic tube 908 is fixedly connected to the surface of the tail clamping plate 902. When the motor 906 drives the screw 907 to rotate, the screw 907 drives the tail clamping plate 902 to move linearly along the limiting groove 901 through the threaded connection with the telescopic tube 908, thereby realizing the precise movement of the tail clamping plate 902 and thus realizing the stretching operation of the wire harness.

[0031] Guide slide rods 14 are inserted through both sides of the cutting frame 6. The guide slide rods 14 guide the movement of the cutting frame 6, so that it can remain stable and straight during the movement, which further improves the cutting accuracy and stability of the cutting blade 8.

[0032] Both ends of the guide slide rod 14 are fixedly connected to support seats 15.

[0033] The support base 15 is fixedly connected to the upper surface of the mounting platform 1.

[0034] The implementation principle of the wire harness processing cutting device in this embodiment is as follows: The operator first places the head end of the wire harness on the surface of the head clamping plate 10. Then, by rotating the handle 13, the handle 13 drives the bidirectional lead screw 12 to rotate, causing the head clamping blocks 11 on both sides to move synchronously towards the center under the action of the threads, thereby firmly clamping and fixing the head end of the wire harness. Next, the operator places the tail end of the wire harness on the surface of the tail clamping plate 902 and rotates the handle 905. The handle 905 drives the bidirectional lead screw 904 to rotate, causing the tail clamping blocks 903 on both sides to move synchronously towards the center under the action of the threads, thereby clamping and fixing the tail end of the wire harness. After clamping the wire harness, the operator starts the motor 90. 6. Its output end drives the screw 907 to rotate. Since the screw 907 is threadedly connected to the telescopic tube 908 and the telescopic tube 908 is fixed on the surface of the tail clamping plate 902, the rotation of the screw 907 will drive the tail clamping plate 902 to move linearly along the limiting groove 901. During the backward movement of the tail clamping plate 902, it will stretch the wire harness to keep it taut and avoid cutting errors caused by the wire harness being loose or sagging during the cutting process, thereby improving the cutting accuracy. At the same time, the output end of the motor 3 drives the lead screw 4 to rotate. The lead screw 4 is threadedly connected to the connecting sleeve 5 and drives the cutting frame 6 to move along the limiting groove 2. When the cutting frame 6 moves to the predetermined position, the cylinder 7 is activated and pushes the cutting blade 8 to perform the cutting operation.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
