Description

Technical Field

[0001] This application belongs to the technical field of wire harness cutting equipment, specifically a high-precision wire harness cutting equipment. Background Technology

[0002] In fields such as electronics, automotive manufacturing, and aerospace, wire harnesses are key components for transmitting power and signals, and their processing precision directly affects equipment performance and reliability. With the widespread adoption of intelligent devices, the market demand for high-precision, customized wire harnesses continues to rise. As a fundamental and crucial process, wire harness cutting has garnered significant attention for its processing efficiency and precision.

[0003] Traditional wire harness cutting relies heavily on manual operation. Workers must manually measure, mark, and cut the wire harnesses, which is not only inefficient and unable to meet the needs of large-scale production, but also prone to significant accuracy errors. For example, in automotive wire harness production, different car models require significantly different wire harness specifications. Manual cutting is susceptible to fatigue and measurement deviations, leading to inconsistent lengths and affecting the overall vehicle assembly quality. Even when some companies use semi-automatic cutting equipment, manual assistance is still required for wire feeding and positioning. This results in low automation levels, making it difficult to achieve precise cutting of complex wire harnesses, and offering limited improvements in production efficiency.

[0004] To address the aforementioned issues, a high-precision wire harness cutting device is proposed. Utility Model Content

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

[0006] The technical solution adopted in this application is as follows: A high-precision wire harness cutting device includes a base. A cutting mechanism and a wire pulling mechanism are fixedly installed on the left and right sides of the upper surface of the base, respectively. A support plate is fixedly installed in the middle of the upper surface of the cutting mechanism. Multiple connecting holes are opened on the upper surface of the support plate. A lower cutting blade is fixedly installed on one side of the upper surface of the cutting mechanism. Connecting rods are fixedly installed on both sides of the upper surface of the cutting mechanism. A top plate is fixedly installed on the top of the connecting rod. A movable plate is slidably connected to the outer wall of the connecting rod. A pressure plate and an upper cutting blade are fixedly installed at the bottom of the movable plate. A slide rail is fixedly installed on the upper surface of the wire pulling mechanism. An electric slider is slidably connected to the outer wall of the slide rail. A moving plate is fixedly installed on the top of the electric slider. A lower clamping plate is fixedly installed on one side of the moving plate. A second cylinder is fixedly installed on the other side of the upper surface of the moving plate. An upper clamping plate is fixedly installed on one side of the output shaft of the second cylinder.

[0007] By adopting the above technical solution, the cable to be cut is placed inside the connecting hole on the upper surface of the support plate. After placement, the electric slider drives the moving plate to move along the slide rail, thereby moving the lower clamping plate to below the cable. The second cylinder retracts, driving the upper clamping plate downward, thereby clamping the cable through the upper and lower clamping plates. After clamping, the electric slider drives the moving plate to move and reset along the slide rail, thereby pulling the cable outward. When the cable is pulled up to the required length, the movable plate moves downward along the connecting rod. During the movement of the movable plate, the pressure plate first presses the cable, and at the same time, the upper and lower cutters contact to cut the cable. After the cable is cut, the above operation is repeated to automatically cut the cable.

[0008] In a preferred embodiment, a guide rod is fixedly installed on one side of the upper surface of the base, a slider is slidably connected to the outer wall of the guide rod, a stop rod is fixedly installed on one side of the slider, and a pressure sensor is fixedly installed on the side of the moving plate near the stop rod. The pressure sensor is electrically connected to the electric slider.

[0009] By adopting the above technical solution, during the cable cutting process, the position of the stop bar is adjusted by pulling the slider along the guide rod. During the cable cutting process, when the pressure sensor on the rear side of the moving plate contacts the stop bar, the pressure sensor transmits an electrical signal to the electric slider. After receiving the electrical signal, the electric slider stops working, thereby accurately controlling the cutting length.

[0010] In a preferred embodiment, a scale is provided on the upper surface of the guide rod.

[0011] By adopting the above technical solution, the position of the slider can be precisely adjusted using a scale.

[0012] In a preferred embodiment, a first cylinder is fixedly installed on the top of the top plate, and the output shaft of the first cylinder is fixedly connected to the upper wall of the movable plate.

[0013] By adopting the above technical solution, the first cylinder drives the movable plate to move up and down.

[0014] In a preferred embodiment, the upper end of the slider is threaded with a locking bolt.

[0015] By adopting the above technical solution, after the slider moves, the position of the slider is fixed by locking bolts.

[0016] In a preferred embodiment, anti-slip pads are fixedly installed at all four corners of the bottom of the base.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0018] 1. In this application, the cable to be cut is placed inside the connecting hole on the upper surface of the support plate. After placement, the electric slider drives the moving plate to move along the slide rail, thereby moving the lower clamping plate below the cable. The second cylinder retracts, driving the upper clamping plate downward, thereby clamping the cable through the upper and lower clamping plates. After clamping, the electric slider drives the moving plate to move and reset along the slide rail, thereby pulling the cable outward. When the cable is pulled up to the required length, the movable plate moves downward along the connecting rod. During the movement of the movable plate, the pressure plate first presses the cable, and at the same time, the upper and lower cutters contact to cut the cable. After the cable is cut, the above operation is repeated to automatically cut the cable.

[0019] 2. In this application, during the cable cutting process, the position of the stop bar is adjusted by pulling the slider to move it along the guide rod. During the cable cutting process, when the pressure sensor on the rear side of the moving plate contacts the stop bar, the pressure sensor transmits an electrical signal to the electric slider. After receiving the electrical signal, the electric slider stops working, thereby accurately controlling the cutting length. Attached Figure Description

A pressure sensor 37 is fixedly installed on the side of the moving plate 33 near the stop bar 14. The pressure sensor 37 is electrically connected to the electric slider 32. During the cable cutting process, the slider 12 is pulled to move along the guide rod 11, thereby adjusting the position of the stop bar 14. During the cable cutting process, when the pressure sensor 37 on the rear side of the moving plate 33 contacts the stop bar 14, the pressure sensor 37 transmits an electrical signal to the electric slider 32.

After clamping, the electric slider 32 drives the moving plate 33 to move and reset along the slide rail 31, thereby pulling the cable outward. When the cable is pulled up to the required length, the movable plate 27 moves downward along the connecting rod 24. During the movement of the movable plate 27, the pressure plate 23 first presses the cable, and at the same time, the upper cutter 28 and the lower cutter 22 contact to cut the cable.
