Description

Technical Field

[0001] This utility model mainly relates to the field of stranding equipment technology, specifically to a stranding machine for automotive wiring harness production. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there would be no automotive electrical system. They consist of copper terminals crimped to wires and cables, then encapsulated in insulating material or a metal casing and bundled together to form a circuit network. They are the physical carrier of the automotive electrical system and are often referred to as the "bridge" of the vehicle's electrical system.

[0003] In the manufacturing process of automotive wiring harnesses, stranding equipment is inevitably used to twist multiple wires into a single strand to meet usage requirements. As a core piece of equipment for laying cables, optical fibers, and steel wire ropes, stranding equipment is widely used in power construction, communication engineering, and building infrastructure for stranding various soft / hard conductor wires. However, traditional stranding equipment is relatively complex in design, generally only able to strand one group of wires at a time, resulting in low work efficiency and inconvenience. Furthermore, workers may accidentally touch the rotating clamping end during stranding, posing a safety hazard. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a stranding machine for automotive wiring harness production, which solves the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a stranding machine for automotive wiring harness production, comprising a stranding machine frame, a supporting base frame corresponding to the bottom of the stranding machine frame, a control box corresponding to one side of the top of the stranding machine frame, and a position-adjustable tailstock corresponding to the other side of the top of the stranding machine frame. A clamping seat is provided between the tailstock and the control box in a telescopically movable manner. Multiple two-finger electric grippers for clamping the wiring harness are respectively installed on the opposite side of the clamping seat and the control box. The two-finger electric grippers on the clamping seat and the two-finger electric grippers on the control box are symmetrically arranged and at the same height. The two-finger electric grippers on the control box are driven to rotate. A protective rod that is driven to extend and retract is also provided at the top front of the side of the control box where the two-finger electric grippers are located. When the stranding machine is performing stranding work, the protective rod extends; when the stranding machine is not performing stranding work, the protective rod retracts.

[0009] Furthermore, the top front and rear sides of the stranding machine frame are provided with corresponding slide rails, and the bottom front and rear sides of the tailstock and clamping seat are respectively equipped with pulleys. The pulleys are respectively equipped with brakes. The tailstock and clamping seat are slidably installed on the slide rails through the pulleys, and the pulleys are fixed on the slide rails by the brakes.

[0010] Furthermore, a first telescopic element is installed on the side of the tailstock near the clamping seat, and the clamping seat is connected to the telescopic rod end of the first telescopic element.

[0011] Furthermore, a second telescopic element is installed in a corresponding position inside the control box, and the protective rod is connected to the telescopic rod end of the second telescopic element.

[0012] Furthermore, multiple drive motors are installed in corresponding positions inside the control box, and the two-finger electric grippers on the control box are respectively installed on the output shafts of the drive motors.

[0013] Furthermore, a partition is provided at the top center of the stranding machine frame to separate the top of the stranding machine frame from front to back. A first placement groove is formed between the partition and the rear slide rail, and a second placement groove is formed between the partition and the front slide rail. The first placement groove can be used to place stranded wire bundles, and the second placement groove can be used to place unstretched wire bundles.

[0014] Furthermore, a control panel is provided on the front side of the control box, and a PLC control system is provided inside the control box. The two-finger electric gripper, the first telescopic element, the second telescopic element, and the drive motor are all electrically connected to the PLC control system inside the control box.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This utility model is reasonably designed and can perform multiple wire harness twisting operations simultaneously. During twisting, the two ends of two, three, or more wire harnesses are clamped onto the two-finger electric grippers on the control box and clamping base, respectively. Then, the two-finger electric grippers on the control box are driven to rotate, which effectively improves work efficiency. It can also twist wire harnesses of different lengths. Its overall operation is very flexible and convenient. The protective rod can also effectively prevent workers from accidentally touching the rotating two-finger electric grippers during twisting, thus improving its safety. Its overall design is simple and ingenious, flexible and convenient to use, and highly practical, making it worthy of promotion.
