Description

Technical Field

[0001] This utility model relates to the field of wire stripping and terminal crimping machines, and in particular to a wire harness processing wire stripping and terminal crimping machine. Background Technology

[0002] Wire harness processing refers to a series of processes such as cutting, stripping, and crimping terminals on wires and cables to produce wire harness products that meet specific requirements. This process usually uses a stripping and crimping machine, which can perform stripping and crimping operations quickly and continuously. Using a stripping and crimping machine can ensure that the wire harness connection quality of each product is stable and reliable.

[0003] In traditional wire stripping and terminal crimping machines, wire harnesses enter the machine via an automatic wire feeding device. This feeding device typically consists of a motor, rollers, and a conveyor belt, smoothly transporting the wire harness to the processing position. A sliding plate, mounted on a sliding base, can also slide along the X-axis, driving the stripping blades to perform the stripping operation. There are generally two opposing stripping blades; their relative movement cuts the wire sheath. The crimping mechanism, located above the stamping mechanism, is the main component for the crimping operation. As it moves downwards, it applies pressure to the terminals, crimping them together with the wire. The shape and size of the upper cutter must match the type and specifications of the terminals to ensure the quality and effectiveness of the crimping.

[0004] However, the blades of traditional wire stripping machines are usually fixed in one position on the equipment, and can only perform linear or rotary cutting in one direction. This structure limits the cutting angle and method of the blades on the wire. For some irregularly shaped or special materials, it is impossible to achieve all-round and uniform stripping operation, which can easily lead to incomplete stripping or damage to the internal conductors. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wire harness stripping and terminal cutting machine, which aims to improve the problem that traditional stripping machines cannot achieve all-round and uniform stripping operations, which easily leads to incomplete stripping or damage to internal wires.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire harness stripping and terminal crimping machine, comprising a machine body, a wire feeder fixedly connected to the side wall of the machine body, a cutting component provided on the side wall of the machine body, and a terminal crimping component provided on the side wall of the machine body, wherein the terminal crimping component crimps the terminals to the wires of the wire harness.

[0007] The cutting assembly includes a connecting platform, multiple connecting platforms are fixedly connected to the side wall of the machine body, a motor is fixedly connected to the side wall of the connecting platform, a rotating wheel is fixedly connected to the output end of the motor, a collision platform is fixedly connected to the top of each connecting platform, a wire groove is opened inside the rotating wheel, multiple rotating shafts are rotatably connected to the side wall of the rotating wheel, a connecting plate is fixedly connected to the top of the rotating shaft, and a wire stripping head is fixedly connected to the top of the connecting plate.

[0008] Furthermore, the end-cutting assembly includes an end-cutting device, which is fixedly connected to the side wall of the machine body.

[0009] Furthermore, a support platform is fixedly connected to the side wall of the machine body, and multiple turntables are fixedly connected to the top of the support platform.

[0010] Furthermore, the turntables are rotatably connected by a connecting shaft, and a pressure plate is fixedly connected to the side wall of the connecting shaft.

[0011] Furthermore, a rotating plate is fixedly connected to one end of the connecting shaft, and a sliding groove is provided inside the rotating plate.

[0012] Furthermore, an electric push rod is fixedly connected to the top of the support platform, and a slider is fixedly connected to the output end of the electric push rod.

[0013] Furthermore, a slide rail is fixedly connected to the upper surface of the support platform, and the slider is slidably connected inside the slide rail.

[0014] Furthermore, a connecting frame is rotatably connected to the top of the slider, and a sliding shaft is fixedly connected to both ends of the connecting frame, with the sliding shaft slidably connected inside the slide groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor first outputs power to the rotating wheel, which then rotates between the connecting platforms. Finally, the connecting plates rotate synchronously and change their tilt angle. The movement of multiple connecting plates drives the wire stripping head to strip the wire bundle inside the wire groove. This allows the blade to cut the wire from different angles, resulting in a more uniform and thorough stripping effect. In particular, it can better adapt to the shape characteristics of round or elliptical wires, thus improving the stripping quality.

[0017] 2. In this utility model, the electric push rod pushes the slider at its output end, causing the slider to slide inside the slide rail. Finally, the connecting frame rotates inside the slider and changes its tilt angle. Then, the sliding shaft at one end of the connecting frame slides further in the slide groove inside the rotating plate. At this time, the rotating plate can be rotated under force and drive the connecting shaft to rotate between the turntables. The rotation of the connecting shaft further drives the angle of the wire pressing plate to change, effectively fixing the wire harness, and then entering the end-cutting device for end-cutting work.

[0023] 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.

[0024] Reference Figures 1-2 The present invention provides an embodiment of a wire harness stripping and terminal crimping machine, comprising a machine body 1, a wire feeder 2 fixedly connected to the side wall of the machine body 1, the wire feeder 2 being composed of a roller motor capable of automatically feeding wires, a cutting component provided on the side wall of the machine body 1, and a terminal crimping component provided on the side wall of the machine body 1, the terminal crimping component being used to crimp the terminals to the wires of the wire harness.

[0025] The cutting assembly includes a connecting platform 4, which supports the top impact platform 6. Multiple connecting platforms 4 are fixedly connected to the side wall of the machine body 1. A motor 5 is fixedly connected to the side wall of the connecting platform 4. A rotating wheel 3 is fixedly connected to the output end of the motor 5. The rotation of the rotating wheel 3 strips the wire harness. Each connecting platform 4 has an impact platform 6 fixedly connected to its top. The impact platform 6 can squeeze the wire stripping head 9 when it touches it. A wire groove 10 is opened inside the rotating wheel 3. The wire groove 10 keeps the wire harness in a stable position. Multiple rotating shafts 7 are rotatably connected to the side wall of the rotating wheel 3. The rotating shafts 7 can drive the wire stripping head 9 to rotate when it is squeezed. A connecting plate 8 is fixedly connected to the top of the rotating shaft 7. The wire stripping head 9 is fixedly connected to the top of the connecting plate 8.

[0026] Specifically, firstly, when stripping the wire is required, the wire is fed through the wire feeder 2 into the wire groove 10 inside the rotating wheel 3. Then, the motor 5 is started, which outputs power to the rotating wheel 3, causing it to rotate between the connecting platforms 4. During the rotation of the rotating wheel 3, the stripping blade 9 touches the impact platforms 6 on both sides. At this time, the stripping blade 9 is squeezed by the impact platforms 6 and forced towards the center. Meanwhile, the rotating shaft 7 rotates on the side wall of the rotating wheel 3, thereby causing the connecting plate 8 on top to rotate synchronously and change its tilt angle. The movement of multiple connecting plates 8 can drive the stripping blade 9 to strip the wire bundle inside the wire groove 10, allowing the blade to cut the wire from different angles, resulting in a more uniform and thorough stripping effect. This is especially beneficial for round or elliptical wires, as it better adapts to their shape characteristics, thereby improving the quality of stripping.

[0027] Reference Figure 3 The termination assembly includes a termination tool 11, which has crimping terminals inside to terminate the wire harness. The termination tool 11 is fixedly connected to the side wall of the body 1. A support platform 12 is fixedly connected to the side wall of the body 1. Multiple turntables 13 are fixedly connected to the top of the support platform 12, and the turntables 13 provide rotational support for the connecting shaft 14. The connecting shaft 14 is rotatably connected between the turntables 13. A wire clamping plate 22 is fixedly connected to the side wall of the connecting shaft 14 to ensure the stability of the wire harness during termination. A rotating plate 15 is fixedly connected to one end of the connecting shaft 14, and the rotating plate 15 has an internal opening... The slide groove 16 provides a sliding track for the slide shaft 21. An electric push rod 17 is fixedly connected to the top of the support platform 12. A slider 19 is fixedly connected to the output end of the electric push rod 17. A slide rail 18 is fixedly connected to the upper surface of the support platform 12. The slide rail 18 keeps the slider 19 sliding in a straight line. The slider 19 is slidably connected inside the slide rail 18. A connecting frame 20 is rotatably connected to the top of the slider 19. Slide shafts 21 are fixedly connected to both ends of the connecting frame 20. When the connecting frame 20 rotates, the slide shafts 21 push the rotating plate 15. The slide shafts 21 are slidably connected inside the slide groove 16.

[0028] Specifically, after the wire harness stripping operation is completed, the electric push rod 17 is activated. The electric push rod 17 pushes the slider 19 at its output end, causing the slider 19 to slide inside the slide rail 18. While the slider 19 slides inside the slide rail 18, it causes the connecting frame 20 at its top to move accordingly. The connecting frame 20 rotates inside the slider 19 and changes its tilt angle. Subsequently, the sliding shaft 21 at one end of the connecting frame 20 slides further in the sliding groove 16 inside the rotating plate 15. At this time, the rotating plate 15 can be rotated under force, causing the connecting shaft 14 to rotate between the turntables 13. The rotation of the connecting shaft 14 will further change the angle of the wire clamping plate 22, thereby effectively fixing the wire harness. Then, the fixed wire harness can enter the terminal breaker 11 for terminal breaking.

[0029] Working principle: When stripping the wire, the wire is fed into the wire groove 10 inside the rotating wheel 3 by the wire feeder 2. The motor 5 is started, and the motor 5 outputs power to the rotating wheel 3, causing the rotating wheel 3 to rotate between the connecting platforms 4. During the rotation of the rotating wheel 3, the stripping head 9 will touch the impact platforms 6 on both sides. At this time, the stripping head 9 will be squeezed inward by the impact platforms 6. At this time, the rotating shaft 7 will rotate on the side wall of the rotating wheel 3, thereby driving the connecting plate 8 on top to rotate synchronously and change the tilt angle. The movement of multiple connecting plates 8 drives the stripping head 9 to strip the wire bundle inside the wire groove 10, so that the blade can cut the wire from different angles, and the stripping effect is more uniform and thorough, especially for round or oval-shaped wires. To better adapt to its shape and improve stripping quality, after the wire harness is stripped, the electric push rod 17 is activated. The electric push rod 17 pushes the slider 19 at its output end, causing the slider 19 to slide inside the slide rail 18. As the slider 19 slides inside the slide rail 18, it drives the connecting frame 20 at its top to follow the displacement. The connecting frame 20 rotates inside the slider 19 and changes its tilt angle. Then, the sliding shaft 21 at one end of the connecting frame 20 further slides in the sliding groove 16 inside the rotating plate 15. At this time, the rotating plate 15 can be rotated under force and drive the connecting shaft 14 to rotate between the turntables 13. The rotation of the connecting shaft 14 further drives the angle of the wire clamping plate 22 to change, effectively fixing the wire harness, and then entering the terminal breaker 11 for terminal breaking work.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
