Description

Technical Field

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

[0002] Automotive wiring harnesses are the main network of automotive circuits; without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly consisting of copper stamped contact terminals crimped to wires and cables, then covered with plastic insulation or an outer metal shell, and bundled together to form a connected circuit.

[0003] Existing wire harness cutting devices have the drawback of not being able to stably support and fix the wire harness when cutting it. This design flaw makes it difficult to keep the position of the wire harness stable during the cutting process, which in turn forces the operator to frequently adjust the position of the wire harness to ensure the accuracy of the cut. Utility Model Content

[0004] The purpose of this utility model is to provide a wire harness cutting device for automotive wiring harnesses. By setting a cutting mechanism, it not only improves the cutting accuracy but also greatly improves the work efficiency, avoiding the problem of multiple adjustments and wasted time caused by unstable wire harness position. It also solves the problem that existing wire harness cutting devices are not convenient for stable support and fixation of wire harnesses when cutting them.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a wire harness cutting device for automotive wire harnesses, including a processing table and a wire harness, wherein the processing table is provided with a cutting mechanism and a wire pulling mechanism;

[0007] The cutting mechanism includes a fixed platform fixedly connected to the top surface of the processing table. Two fixed frames are fixedly connected to the top surface of the processing table. A motor is fixedly connected to the top surface of the front fixed frame. The output end of the motor is fixedly connected to a bidirectional threaded rod through a coupling. The bottom end of the bidirectional threaded rod extends to the top surface of the processing table and is rotatably connected to the top surface of the processing table. A slide rod is fixedly connected to the inner top wall of the rear fixed frame. A movable plate and a movable plate are threadedly connected to the outer wall of the bidirectional threaded rod. The slide rod passes through the movable plate and the movable plate. The slide rod is slidably connected to both the movable plate and the movable plate, which can drive the motor to rotate the bidirectional threaded rod, so that the movable plate and the movable plate can move closer to each other.

[0008] The wire pulling mechanism includes a fixed plate fixedly connected to the top surface of the processing table, and an electric push rod is fixedly connected to the fixed plate. The fixed plate is used to fix and support the electric push rod.

[0009] Furthermore, a plurality of sliding rods 2 are passed through the movable plate 1, and the plurality of sliding rods 2 are slidably connected to the movable plate 1. A pressure plate is fixedly connected to the bottom end of the plurality of sliding rods 2. The bottom surface of the pressure plate and the top surface of the fixed platform are respectively in contact with the outer wall of the wire harness. The pressure plate and the fixed platform cooperate with each other to fix the multi-strand wire harness.

[0010] Furthermore, spring 1 is wound around the outer wall of several of the slide rods 2. One end of each of the spring 1 is fixedly connected to the top surface of the pressure plate, and the other end of each of the spring 1 is fixedly connected to the bottom surface of the moving plate 1. The multiple spring 1s cooperate with the slide rods 2 to provide movement stroke and clamping force for fixing the wire harness.

[0011] Furthermore, both the bottom surface of the first movable plate and the top surface of the second movable plate are fixedly connected with cutting blades. Both cutting blades are in contact with the wire harness, and the two cutting blades can cut the wire harness when they are close to each other.

[0012] Furthermore, the output end of the electric push rod is fixedly connected to a connecting plate, and the top surface of the processing table is fixedly connected to two upright plates, each of which has a sliding groove on one side that is close to the other.

[0013] Furthermore, two sliding rods (3) extend through the connecting plate, and both sliding rods (3) are fixedly connected to the connecting plate.

[0014] Furthermore, two clamping plates are slidably connected to the outer walls of the two slide rods three. The two clamping plates are symmetrically arranged with the connecting plate as the central axis, so that the two clamping plates can only slide up and down on the outer walls of the slide rods three, thus limiting the movement of the clamping plates.

[0015] Furthermore, two springs are wound around the outer walls of both slide rods three. One end of each of the four springs two is fixedly connected to the clamping plate, and the other end of each of the four springs two is fixedly connected to the connecting plate. Rollers are rotatably connected to the opposite sides of the two clamping plates. Several rollers are slidably connected to the inner wall of the slide groove. Through the mutual restraint between the rollers and the slide groove, the clamping plate can be limited to move according to the inner wall structure of the slide groove.

[0016] This utility model has the following beneficial effects:

[0017] 1. By incorporating a cutting mechanism, the positioned wire harness is cut as the moving plate 1 and moving plate 2 continuously approach each other, preventing the wire harness from loosening or shifting during the cutting process. This not only improves the cutting accuracy but also greatly increases work efficiency, avoiding the problems of multiple adjustments and wasted time caused by unstable wire harness positions. It achieves stable fixation of the wire harness, ensuring that each cut is performed in the optimal position, thus guaranteeing neat and smooth cut edges.

[0018] 2. By setting up a wire pulling mechanism, not only can the cut wire bundle be pulled and stretched again, but wire bundles of different lengths can also be cut according to needs, which greatly improves the overall production efficiency and flexibility of the device, significantly shortens the production cycle, and improves resource utilization.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Please see Figure 1-5 As shown, this utility model is a wire harness cutting device for automotive wire harnesses, including a processing table 1 and a wire harness 4. The processing table 1 is provided with a cutting mechanism 2 and a wire pulling mechanism 3.

[0030] The cutting mechanism 2 includes a fixed platform 21 fixedly connected to the top surface of the processing table 1. Two fixed frames 22 are fixedly connected to the top surface of the processing table 1. A motor 23 is fixedly connected to the top surface of the front fixed frame 22. The output end of the motor 23 is fixedly connected to a bidirectional threaded rod 24 via a coupling. The bottom end of the bidirectional threaded rod 24 extends to the top surface of the processing table 1 and is rotatably connected to the top surface of the processing table 1. A slide rod 25 is fixedly connected to the inner top wall of the rear fixed frame 22. A movable plate 26 and a movable plate 27 are threadedly connected to the outer wall of the bidirectional threaded rod 24. The slide rod 25 passes through the movable plate 26 and the movable plate 27, and is slidably connected to both the movable plate 26 and the movable plate 27. Several slide rods 28 pass through the movable plate 26, and are slidably connected to the movable plate 26. The bottom ends of the slide rods 28 are fixedly connected to... A pressure plate 29 is attached, with its bottom surface and the top surface of the fixed platform 21 respectively contacting the outer wall of the wire harness 4. Several sliding rods 28 have springs 291 wound around their outer walls. One end of each spring 291 is fixedly connected to the top surface of the pressure plate 29, and the other end is fixedly connected to the bottom surface of the moving plate 26. Cutters 292 are fixedly connected to the bottom surface of the moving plate 26 and the top surface of the moving plate 27, with both cutters 292 contacting the wire harness 4. The cutting mechanism 2 prevents the wire harness 4 from loosening or shifting during the cutting process, improving cutting accuracy and significantly increasing work efficiency. It avoids the problems of multiple adjustments and wasted time caused by unstable wire harness positions, making the entire cutting process smoother. Operators can focus on other important aspects, reducing fatigue caused by frequent adjustments. Simultaneously, the precise cutting effect provides a more reliable foundation for subsequent assembly and processing, ensuring product quality stability.

[0031] The wire pulling mechanism 3 includes a fixed plate 31 fixedly connected to the top surface of the processing table 1. An electric push rod 32 is fixedly connected to the fixed plate 31. A connecting plate 33 is fixedly connected to the output end of the electric push rod 32. Two upright plates 34 are fixedly connected to the top surface of the processing table 1. Slide grooves 35 are opened on the side of the two upright plates 34 that are close to each other. Two sliding rods 36 pass through the connecting plate 33. The two sliding rods 36 are fixedly connected to the connecting plate 33. Two clamping plates 37 are slidably connected to the outer walls of the two sliding rods 36. The two clamping plates 37 are symmetrically arranged about the connecting plate 33 as the central axis. Two springs 38 are wound around the outer walls of the two sliding rods 36. One end of the four springs 38 All are fixedly connected to the clamping plate 37, and the other ends of the four springs 38 are fixedly connected to the connecting plate 33. Rollers 39 are rotatably connected to the opposite sides of the two clamping plates 37. Several rollers 39 are slidably connected to the inner wall of the slide groove 35. By setting the wire pulling mechanism 3, not only can the cut wire bundle 4 be pulled and stretched again, but wire bundles 4 of different lengths can also be cut according to needs, which greatly improves the production efficiency and flexibility of the overall device. This design concept fully considers the diverse needs in the production process, so that each component can be adjusted according to the specific production plan, thereby minimizing material waste and production cycle.

[0032] A specific application of this embodiment is as follows: By setting a cutting mechanism 2, the bidirectional threaded rod 24 is rotated by the drive motor 23. With the cooperation of the slide bar 25, the moving plate 26 and the moving plate 27 on the bidirectional threaded rod 24 move relative to each other. At this time, multiple springs 291 are compressed under the action of the slide bar 28, so that the pressure plate 29 on the moving plate 26 presses down on multiple wire harnesses 4 to position the wire harnesses 4. As the moving plate 26 and the moving plate 27 continue to approach each other, the positioned wire harnesses 4 will be cut, avoiding the loosening and displacement of the wire harnesses 4 during the cutting process. This not only improves the cutting accuracy but also greatly improves the work efficiency, avoiding the problem of multiple adjustments and wasted time caused by unstable wire harness positions.

[0033] By setting up the wire pulling mechanism 3, before cutting multiple wire harnesses 4, the electric push rod 32 can be driven to move the connecting plate 33. The two slide rods 36 on the connecting plate 33 will also move accordingly. The two slide rods 36 will move the clamping plate 37. Under the action of the roller 39 and the slide groove 35, when the two clamping plates 37 move towards the fixed platform 21, the two clamping plates 37 move away from each other and then move towards each other, so that the two clamping plates 37 can clamp and fix multiple wire harnesses 4. The multiple springs 38 are compressed after rebounding, and the electric push rod 32 drives the connecting plate 33 to move away from the fixed platform 21. At this time, multiple wire harnesses 4 will move synchronously, and the second spring 38 will always be in a compressed state. After moving to a certain distance, the wire harness 4 can be cut according to the length requirements of the wire harness 4. After the multiple wire harnesses 4 are cut, the electric push rod 32 can drive the connecting plate 33 to move towards the fixed platform 21 again. At this time, the multiple compressed springs 38 are released, which makes the two connecting plates 33 move away from each other. Not only can the cut wire harness 4 be pulled and stretched again, but it can also be cut into wire harnesses 4 of different lengths according to the requirements, which greatly improves the production efficiency and flexibility of the overall device.
