Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically to an electric vehicle cable cutting device. Background Technology

[0002] In the field of electric vehicle manufacturing, cables are key components for power transmission and signal control, and their processing quality directly affects the performance and safety of the entire vehicle.

[0003] Existing cutting devices mostly employ a fixed traction mode, lacking a dynamic tension adjustment mechanism. When conveying elastic cables (such as rubber-insulated wires), the traction speed does not match the cable's tensile characteristics, easily causing deviations in the actual cutting length, and even leading to internal core wire breakage due to overstretching. Simultaneously, non-linearly conveyed cables are prone to friction with the conveying mechanism, resulting in sheath wear or deformation. Furthermore, traditional cutting devices often control the cutting length through manual measurement markings or fixed limit blocks, requiring frequent stops for adjustments and failing to adapt to rapid production changes for multiple cable specifications. Existing devices commonly use bolt tightening or bushing interference fits for cable reel installation, requiring operators to use wrenches and other tools for disassembly and reel changing, resulting in time-consuming reel changes and increased equipment costs and management complexity.

[0015] This utility model relates to an electric vehicle cable cutting device, which has significant technical advantages and positive effects compared with the prior art, as detailed below:

[0016] 1. By incorporating a movable stabilizing clamp supported by an electric telescopic rod and equipped with servo motor-driven rollers, this device can automatically adjust the traction speed to maintain constant cable tension. This effectively avoids cable stretching or slack caused by uneven tension, ensuring the cable maintains a stable shape throughout the cutting process. The evenly arranged rollers on the inner side of the movable stabilizing clamp allow the cable to be transported in a straight line between the two clamps. This straight-line transport method not only improves cable transport efficiency but also reduces friction and wear during transport, extending the cable's service life.

[0017] 2. A rotating wheel is mounted on one side of the cutting frame using a movable bracket, and an encoder connected to the wheel's shaft enables real-time monitoring of the cable feed length. This allows operators to precisely control the cable cutting length, avoiding material waste caused by inaccurate length control in traditional cutting methods. The spring design connecting the movable bracket and the cutting frame ensures that the rotating wheel always contacts the cable, further improving measurement accuracy and reliability. This precise length control not only improves production efficiency but also significantly enhances product quality.

[0018] 3. The movable pressing blocks on both sides of the drum can flexibly unfold or close under the action of the lead screw and connecting rod. This greatly simplifies the cable reel assembly and disassembly process, allowing operators to quickly and easily replace and secure the cable reel, reducing downtime and improving production efficiency. The threaded rods with opposite thread directions at both ends of the lead screw, along with the handwheel extending to the outside of the drum, allow operators to easily control the unfolding and closing of the movable pressing blocks by manually adjusting the handwheel, further enhancing the ease of operation of the device.

[0019] 4. The hydraulic lifting rod installed on the top of the cutting frame, through which the cutting blade is mounted on the blade holder, enables rapid raising and lowering of the cutting blade, improving cutting efficiency. The sliding grooves on both sides of the cutting frame, and the design of the blade holder extending into the sliding grooves at both ends, ensure smooth movement of the cutting blade during cutting, further enhancing cutting accuracy and safety.

[0042] A cable reel 3 is detachably fitted on the outside of the drum 16. The cable reel 3 is fitted on the outside of the drum 16 for easy installation and removal.

[0043] Inside the processing table 1 on the other side of the movable stabilizing clamp 5, there is also a cutting frame 11. A movable frame 9 is provided on one side of the cutting frame 11. A rotating wheel 8 is provided at the bottom of the movable frame 9. An encoder 18 connected to the rotating shaft of the rotating wheel 8 is provided on one side of the movable frame 9.

[0044] The encoder 18 is used to monitor the rotation angle and speed of the wheel 8 in real time, thereby precisely controlling the moving position and speed of the movable frame 9.

[0045] One side of the cutting frame 11 is also provided with bait blocks 19 for mounting the movable frame 9. The inner side of the two bait blocks 19 is also provided with movable shafts 23 connected to the movable frame 9. A spring 10 is also connected between the movable frame 9 and the cutting frame 11.

[0046] The function of spring 10 is to provide a certain elastic force so that the movable frame 9 can remain stable during movement and can automatically reset when needed.

[0047] The processing table 1 below the movable frame 9 is provided with a bracket 14 on top, and the top of the bracket 14 is equipped with a support roller 15 that matches the rotary wheel 8.

[0048] The support roller 15 contacts the rotating wheel 8 to form a rolling support, which improves the stability and accuracy of monitoring.

[0049] A hydraulic lifting rod 12 is installed on the top of the cutting frame 11. The output end of the hydraulic lifting rod 12 extends to the inside of the cutting frame 11 and a cutting blade 28 is installed through the blade holder 24. The inner walls on both sides of the cutting frame 11 are provided with grooves 25, and the two ends of the blade holder 24 extend into the interior of the two grooves 25 respectively.

[0050] A support pad 27 is installed inside the cutting frame 11 below the cutting blade 28, and the top of the support pad 27 is provided with a groove 26 that matches the cutting blade 28.

[0051] The top of the cutting frame 11 has a pre-drilled mounting hole for fixing the hydraulic lifting rod 12.

[0052] The hydraulic lifting rod 12 is hydraulically driven and can move up and down, thereby driving the cutting blade 28 to rise and fall.

[0053] The cutter holder 24 is fixed to the output end of the hydraulic lifting rod 12 and is used to install the cutting blade 28.

[0054] Both ends of the blade holder 24 extend into the grooves 25 on the inner walls of both sides of the cutting frame 11 to ensure that the cutting blade 28 remains horizontal and stable during the lifting and lowering process.

[0055] The slide groove 25 is provided on the inner wall of both sides of the cutting frame 11. The inner wall of the slide groove 25 is smooth to reduce the frictional resistance of the tool holder 24 during the sliding process.

[0056] The cutting blade 28 is mounted on the blade holder 24 and is made of high-hardness alloy material to ensure cutting efficiency and durability.

[0057] The cutting edge 28 is sharp and suitable for cutting a variety of materials.

[0058] The support pad 27 is installed at the bottom inside the cutting frame 11 to support the object being cut.

[0059] The top of the support pad 27 is provided with a groove 26 that matches the cutting blade 28 to ensure complete cutting.

[0060] The groove 26 is located on top of the support pad 27, and its shape matches the cutting edge of the cutting blade 28.

[0061] The function of the groove 26 is to guide the cutting blade 28 to accurately cut into the object being cut, thereby improving the cutting accuracy.

[0062] A material unloading conveyor belt 22 is also installed on the processing table 1 on one side of the cutting frame 11.

[0063] One end of the processing table 1 is provided with a slot 21 for accommodating the unloading conveyor belt 22, so that the unloading conveyor belt 22 can be smoothly embedded into the slot 21.

[0064] An unloading motor 20 is installed on one side of the processing table 1 at the position corresponding to the unloading conveyor belt 22. The unloading motor 20 is connected to the controller 13 set on one side of the cutting frame 11 through a wire.

[0065] When the cut material falls, the unloading motor 20 is started. The unloading motor 20 drives the unloading conveyor belt 22 to transport the cut material from the processing table 1 to the next process or collection area.

[0066] When this application embodiment is used,

[0067] The cable reel 3 is placed on the outside of the roller 16. Rotating the handwheel 33 drives the lead screw 30 to rotate. Because the threads at both ends of the lead screw are in opposite directions, adjusting sleeve 1 34 and adjusting sleeve 2 36 move in opposite directions along the lead screw. This, through the connecting rod 35, causes the movable extrusion block 31 to open to both sides, clamping the inner wall of the cable reel to ensure stable feeding. One end of the cable is pulled out and inserted between the movable stabilizing clamps 5. The electric telescopic rod 17 is activated, pushing the movable stabilizing clamps 5 towards the center of the processing table. The rollers 6 in the grooves 7 of the two clamps contact the cable, forming a clamp. The servo motor 4 drives the rollers 6 to rotate, transporting the cable to the cutting area. The encoder 18 monitors the rotation angle and speed of the rotating wheel 8 in real time, precisely controlling the cable transport length.

[0068] Servo motor 4 drives roller 6 at a set speed, and the cable moves along the processing table towards the cutting frame 11 under the friction of the roller. The rotating wheel 8 at the bottom of the movable frame 9 contacts the support roller 15 on the bracket 14, forming a rolling support to ensure smooth cable delivery. Encoder 18 synchronously records the rotation data of the rotating wheel and calculates the actual cable delivery length. When encoder 18 detects that the cable delivery length has reached the preset value, servo motor 4 stops rotating, roller 6 stops delivering, and the cable position is fixed at this time.

[0069] The controller 13 triggers the hydraulic lifting rod 12, driving the blade holder 24 to descend vertically along the groove 25 on the inner wall of the cutting frame 11, and the cutting blade 28 contacts the cable. The groove 26 on the top of the support pad 27 is aligned with the cutting edge of the cutting blade, guiding the blade to fully cut into the cable and ensuring a flat cut surface.

[0070] After the hydraulic lifting rod 12 reaches the preset stroke, the cutting blade 28 cuts the cable and then rises to reset. The encoder 18 synchronously resets the data to prepare for the next cutting length count.

[0071] The cut cable segment falls onto the unloading conveyor belt 22. The controller 13 starts the unloading motor 20, which drives the unloading conveyor belt 22 to transport the material from the slot 21 to the next process or collection area.
