Description

Technical Field

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

[0002] A stranding machine is a widely used mechanical device for stranding various types of soft and hard conductor wires and electronic wires, turning multiple single conductors into a single strand to meet the processing requirements of the wire. The stranding machine clamps are usually made of metal or other sturdy materials and have specific structures and shapes to firmly clamp and fix multiple wires or cables.

[0003] Existing automotive wiring harness production machines that facilitate the installation of clamps require the wire tension to be maintained within a stable and appropriate range during operation. This prevents the wire from breaking due to excessive tension or loosening due to insufficient tension. When tension fluctuates, workers need to stop the machine in time to adjust it, which not only increases the labor intensity of workers but also reduces production efficiency. Furthermore, some clamps are specially designed for easy installation, requiring specific tools for disassembly, which increases the difficulty of maintenance and reduces the convenience of clamp replacement. Utility Model Content

[0004] The purpose of this invention is to provide a stranding machine for automotive wiring harness production that facilitates the installation of clamps, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stranding machine for automotive wiring harness production that facilitates the installation of clamps, comprising a main body, a fixing frame fixedly connected to the outer side of the main body, a drive shaft disposed inside the main body, a connecting block fixedly connected to one end of the drive shaft, a clamping block disposed on one side of the connecting block, a tension sensor and a controller disposed on the outer side of the main body, and further comprising:

[0006] A drive assembly is provided on one side of the fixed frame. A moving block is provided on the outer side of the drive assembly. A rotating shaft is provided on the inner side of the fixed frame. A rotating block is provided on the outer side of the rotating shaft. A transmission rod is slidably connected to the inner side of the fixed frame. A toggle assembly is provided on the inner side of the rotating block. An adjusting wheel for adjusting the tension of the wire is provided at one end of the transmission rod. A guide assembly for improving the stability of its movement is provided on the outer side of the adjusting wheel.

[0007] A positioning component is provided on one side of the connecting block and the clamping block. A fixing block is fixedly connected to one side of the clamping block. A sliding component is provided on one side of the fixing block. An adjusting block is provided on the outside of the sliding component. A limiting component for fixing the adjusting block is provided inside the connecting block.

[0008] Preferably, the drive assembly includes a motor disposed on one side of the fixed frame, and the output end of the motor is provided with a bidirectional screw.

[0009] Preferably, the actuating assembly includes a first actuating block fixed to the outside of the moving block, a second actuating block fixedly connected to one end of the transmission rod, and vertical and horizontal grooves respectively opened on the inner side of the rotating block.

[0010] Preferably, the guide assembly includes a guide block fixed to the outside of the adjusting wheel, and the inner side of the fixing frame is provided with a guide groove.

[0011] Preferably, the positioning component includes a positioning block fixed to one side of the clamping block, and the inner side of the connecting block is provided with a positioning groove.

[0012] Preferably, the sliding assembly includes a guide rod fixed to one side of the fixed block, a first spring sleeved on the outer side of the guide rod, and a slider fixedly connected to one end of the guide rod.

[0013] Preferably, the limiting component includes a slide rod that slides inside the connecting block, a second spring is sleeved on the outside of the slide rod, and a limiting block is fixedly connected to one end of the slide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes the movement of the first toggle block to cause the rotating block to rotate clockwise around the axis of rotation. As the rotating block rotates, the horizontal groove on the rotating block changes angle. The second toggle block, following the change in the groove angle, drives the transmission rod downwards. This, along with the adjusting wheel, stretches the entire wire. When the appropriate tension range is reached, the adjusting wheel stops moving, eliminating the need to stop the machine to adjust the tension and thus improving production efficiency. By pressing the clamping block, the top of the adjusting block located on one side of the clamping block abuts against the slot inside the connecting block. The slider slides forward along the slot inside the connecting block, causing the fixing block fixed to one end of the guide rod to move forward as well. The fixing block then moves along the arc of the limiting block surface, gradually opening the limiting block and moving it to both sides until the adjusting block disengages from the locking state of the limiting block. This allows for complete disassembly, improving the convenience of clamp replacement. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4As shown, a stranding machine for automotive wire harness production, which facilitates the installation of clamps, includes a main body 1. A fixing frame 2 is fixedly connected to the outside of the main body 1. A drive shaft 3 is installed inside the main body 1. The drive shaft 3 is driven by a power system to easily rotate the clamping blocks 5, so that multiple wires are spirally wound together in a certain arrangement and pitch to form a wire harness with a larger diameter. A connecting block 4 is fixedly connected to one end of the drive shaft 3. A clamping block 5 is installed on one side of the connecting block 4. A tension sensor 6 and a controller 7 are installed on the outside of the main body 1. By installing the tension sensor 6, the tension on the surface of the wires can be monitored. When the tension is too low, to prevent the wire from tangling, the tension sensor 6 transmits a command to the controller 7 indicating that tension adjustment is needed. The controller 7, upon receiving the command from the tension sensor 6, indirectly drives the adjusting wheel 14 to move by activating the motor 81, thus adjusting the wire tension. The system also includes a drive assembly 8 located on one side of the fixed frame 2. A moving block 9 is located on the outer side of the drive assembly 8. The moving block 9 is threaded to the outer side of the bidirectional screw 82. When it moves, it slides along the inner side of the vertical groove in the rotating block 11 via the first lever 131, thereby actuating the rotating block. 11 rotates around the pivot 10; the pivot 10 is provided on the inner side of the fixing frame 2, which facilitates the rotation of the rotating block 11 around the pivot; the rotating block 11 is provided on the outer side of the pivot 10, the transmission rod 12 is slidably connected to the inner side of the fixing frame 2, the actuating component 13 is provided on the inner side of the rotating block 11, one end of the transmission rod 12 is provided with an adjusting wheel 14 for adjusting the tension of the wire, and the outer side of the adjusting wheel 14 is provided with a guide component 15 to improve its movement stability; a positioning component 16 is provided on one side of the connecting block 4 and the clamping block 5, and a fixing block 1 is fixedly connected to one side of the clamping block 5. 7. By setting the fixing block 17 and pressing the clamping block 5, when the fixing block 17 moves to one side, it slides along the surface of the limiting block 203, thereby opening the limiting block 203 and moving it to both sides until the adjusting block 19 is released from the locked state of the limiting block 203, and then the disassembly can be completed; a sliding component 18 is provided on one side of the fixing block 17, and an adjusting block 19 is provided on the outside of the sliding component 18. By setting the adjusting block 19, when the limiting block 203 limits it, the clamping block 5 and the connecting block 4 form a fixed connection; the connecting block 4 is provided with a limiting component 20 for fixing the adjusting block 19.

[0023] The drive assembly 8 includes a motor 81 disposed on one side of the fixed frame 2. When the motor 81 is started, it drives a bidirectional screw 82 to rotate. The output end of the motor 81 is provided with the bidirectional screw 82. When the bidirectional screw 82 rotates, it drives a movable block 9 disposed on the outer side to move parallel. The actuation assembly 13 includes a first actuation block 131 fixed to the outer side of the movable block 9. One end of the transmission rod 12 is fixedly connected to a second actuation block 132. The second actuation block 132 slides within the transverse groove of the rotating block 11. As the rotating shaft 10 rotates, the horizontal groove changes angle, and the second lever 132 moves with the change of the horizontal groove angle, thereby driving the adjusting wheel 14 to adjust the height through the transmission rod 12; and the inner side of the rotating block 11 is provided with vertical groove and horizontal groove respectively; the guide assembly 15 includes a guide block 151 fixed to the outside of the adjusting wheel 14, and the inner side of the fixing frame 2 is provided with a guide groove 152. By setting the guide assembly 15, when the guide block 151 moves with the adjusting wheel 14, the guide groove 152 provides guidance for the movement path of the adjusting wheel 14.

[0024] The positioning component 16 includes a positioning block 161 fixed to one side of the clamping block 5, and a positioning groove 162 is provided on the inner side of the connecting block 4. By setting the positioning component 16, the stability of the clamping block 5 and the connecting block 4 when connected is improved. The sliding component 18 includes a guide rod 181 fixed to one side of the fixing block 17. By setting the guide rod 181, the adjusting block 19 can slide on its outer side. A first spring 182 is sleeved on the outer side of the guide rod 181. By setting the first spring 182, the adjusting block 19 can be pushed back to its original position by the elastic force after it moves. A slider 183 is fixedly connected to one end of the guide rod 181. By setting the slider 183, which is located at one end of the guide rod 181, the adjusting block 19 can be kept in place. The guide rod 181 will not detach from the outside. At the same time, when the top of the adjusting block 19 abuts against the slot inside the connecting block 4, the slider 183 slides forward along the slot inside the connecting block 4. The limiting component 20 includes a slide rod 201 that slides inside the connecting block 4. A second spring 202 is sleeved on the outside of the slide rod 201. One end of the slide rod 201 is fixedly connected to a limiting block 203. By setting the limiting component 20, after the adjusting block 19 enters the connecting block 4, it moves forward along the arc of the surface of the limiting block 203. The limiting block 203 is squeezed and slides to both sides. After the adjusting block 19 reaches one side of the limiting block 203, the second spring 202 pushes the limiting block 203 to reset by inertia and locks it at the bottom of the adjusting block 19, thereby limiting it.

[0025] Working principle: During use, when the tension sensor 6 detects that the wire tension is too low during stranding, the controller 7 starts the motor 81, causing the bidirectional screw 82 to drive the outer moving block 9 forward. Simultaneously, this causes the first shifting block 131 to slide in the vertical groove of the rotating block 11. As the first shifting block 131 moves, it causes the rotating block 11 to rotate clockwise around the axis 10. While the rotating block 11 rotates along the axis 10, the horizontal groove of the rotating block 11 changes angle. The second shifting block 132, following the change in the horizontal groove angle, drives the transmission rod 12 downwards. The adjusting wheel 14 stretches the wire to a certain extent. When the wire reaches the appropriate tension range, the adjusting wheel 14 stops moving. When disassembling the clamping block 5, press the clamping block 5 so that the top of the adjusting block 19 located on one side of the clamping block 5 abuts against the slot inside the connecting block 4. The slider 183 slides forward along the slot inside the connecting block 4. The fixing block 17 fixed to one end of the guide rod 181 moves forward accordingly. Then, the fixing block 17 moves along the arc of the surface of the limiting block 203, gradually opening the limiting block 203 and moving it to both sides until the adjusting block 19 is released from the locking state of the limiting block 203. Then the disassembly can be completed.
