Description

Technical Field

[0001] The utility model relates to the technical field of wire harness cutting, in particular to an automatic cutting tool for an automotive power amplifier wire harness. Background Art

[0002] The automatic cutting tool for an automotive power amplifier wire harness is used for cutting automotive electric wires. Automotive electric wires, also known as low-voltage electric wires, are different from ordinary household electric wires. Ordinary household electric wires are copper single-core electric wires with a certain hardness, while automotive electric wires are all copper multi-core flexible wires. Some of the flexible wires are as thin as hair, and several to dozens of flexible copper wires are wrapped in a plastic insulating tube, which is soft and not easy to break. Due to the particularity of the automotive industry, the manufacturing process of automotive wire harnesses is also more special than that of other ordinary wire harnesses. Specific cutting devices are required in the processing of automotive wire harnesses.

[0003] However, there are certain drawbacks in the use of the cutting devices in the prior art. For example, in the cutting die for an automotive wire harness described in the publication number CN217451922U, it includes a conveying component, which includes a base, a motor arranged on the top of the base, a driving roller arranged at the output end of the motor, and a driven roller arranged below the driving roller; and a cutting component, which includes a fixed frame arranged on the top of the base and a cylinder arranged at the bottom of the fixed frame. The cutting device places the wire harness between the driving roller and the driven roller, drives the driving roller to rotate through the motor to convey the wire harness forward, conveys it to the lower part of the blade, and then the user cuts the wire harness according to requirements. However, the driving roller and the driven roller cannot convey wire harnesses of different sizes simultaneously. When conveying simultaneously, the large wire harness contacts the driving roller and the driven roller, resulting in the small wire harness not being clamped and thus unable to be conveyed. As a result, the cutting device can only cut wire harnesses of the same specification, affecting the cutting efficiency of the cutting device, and the blanking is carried out by gravity, resulting in the wire harness possibly getting stuck at the blanking port during blanking, affecting the use experience.

[0008] Furthermore, connection frames are fixedly connected to the lower surface of the slide seat near both side edges, connection bolts are threadedly connected to the upper surface of the connection frame, and a synchronous belt is fixedly connected to the inside of the connection frame.

[0009] Furthermore, a guiding frame is fixedly connected to the lower surface of the workbench, rotating rollers are rotatably connected to the inner surface of the guiding frame near both the front and rear edges, a conveyor belt is nested on the outer surface of the rotating roller, a one-way bearing is press-fitted to one end of the rotating roller, a synchronous pulley is fixedly connected to the outer ring part of the one-way bearing, and the synchronous belt is meshed with the synchronous pulley.

[0010] Furthermore, the clamping module further comprises a connecting column, a nut, a limiting block and a limiting plate, sliding grooves are formed on both side surfaces of the clamping frame, connecting columns are fixedly connected to both side surfaces of the sliding frame, the connecting columns penetrate through the sliding grooves, a limiting block is nested on the outer surface of the connecting column, a nut is threadedly connected to the outer surface of the connecting column, a limiting plate is fixedly connected to the inner surface of the sliding frame, the upper surface of the pressing frame abuts against the limiting plate, and a fastening bolt is threadedly connected to the bottom surface of the sliding groove.

[0015] When the extrusion column cooperates with the extrusion wheel to contact wire harnesses of different sizes, the airbag inside the sliding frame contacts the extrusion column with a height difference. As the lower pressure frame is pressed down, the airbag is compressed and downward pressure is applied to each extrusion column, so that each extrusion column and the wire harness at the corresponding position of the limiting roller are in close contact. The clamping module on the slide can clamp each wire harness. For the clamping module on the mounting seat, start the stepper motor, and the output end of the stepper motor drives the limiting roller to rotate, so that the limiting roller conveys the wire harness, thereby multiple groups of wire harnesses of different sizes can be conveyed synchronously, which is convenient for later synchronous cutting and improves the cutting efficiency of the device.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present invention, an automatic cutting tool for an automotive power line harness includes a workbench 1. A base foot 101 is fixedly connected to the upper surface of the workbench 1. A slide bar 102 is embedded in the outer surface of the base foot 101. A slide seat 2 is slidably connected to the outer surface of the slide bar 102. A mounting seat 501 is fixedly connected to the upper surface of the workbench 1. Clamping modules 4 are fixedly connected to the upper surfaces of the mounting seat 501 and the slide seat 2. The clamping module 4 includes a clamping frame 401, a sliding frame 403, and a pressing frame 408. Clamping frames 401 are fixedly connected to the upper surfaces of the mounting seat 501 and the slide seat 2. A sliding frame 403 is slidably connected to the inner surface of the clamping frame 401. An airbag 7 is placed inside the sliding frame 403. A pressing frame 408 is slidably connected to the inside of the sliding frame 403. A stepper motor 5 is fixedly connected to the side surface of the clamping frame 401 located on the upper surface of the mounting seat 501. A limit roller 502 is rotatably connected to the inner surface of the clamping frame 401. The output end of the stepper motor 5 is fixedly connected to the limit roller 502. A cutting seat 6 is fixedly connected to the upper surface of the workbench 1. A plurality of extrusion columns 702 matching the limit roller 502 are embedded in the inside of the sliding frame 403. An extrusion wheel 703 is rotatably connected to the lower end of the extrusion column 702.

[0023] Specifically, when in use, multiple groups of wire harnesses are conveyed through the clamping module 4 on the mounting base 501. The wire harnesses are clamped by the clamping module 4 on the sliding seat 2 and pulled out to a predetermined distance, and then cut by the cutting seat 6. Among them, the sliding rod 102 limits the sliding of the sliding seat 2, and the airbag 7 squeezes the extrusion column 702, so that the extrusion wheel 703 at the end of the extrusion column 702 applies a downward pressure to the wire harness in the concave part of the limiting roller 502, assisting in fixing wire harnesses of different thicknesses, facilitating the clamping and conveying of the wire harnesses, achieving the purpose of fixing multiple groups of wire harnesses, further cutting multiple groups of wire harnesses, and improving the working efficiency of the device.

[0024] Embodiment 1

[0025] As Figures 1-2 shown, threaded rods 103 are rotatably connected to the outer surface of the workbench 1 near both side edges. One end of each threaded rod 103 is fixedly connected to a first bevel gear 104. A transmission rod 105 is rotatably connected to the upper surface of the workbench 1 near the front edge. Second bevel gears 106 are fixedly connected to both ends of the transmission rod 105. The second bevel gears 106 are meshed with the first bevel gears 104. A servo motor 107 is fixedly connected to the side surface of the workbench 1. The output end of the servo motor 107 is fixedly connected to the transmission rod 105. The sliding seat 2 is threadedly connected to the threaded rod 103. Connecting frames 201 are fixedly connected to the lower surface of the sliding seat 2 near both side edges. Connecting bolts 202 are threadedly connected to the upper surfaces of the connecting frames 201. A synchronous belt 303 is fixedly connected to the inside of the connecting frames 201.

[0026] In this embodiment, when the servo motor 107 is started, the output end of the servo motor 107 drives the transmission rod 105 to rotate, so that the second bevel gears 106 cooperate with the first bevel gears 104 to drive the two threaded rods 103 to rotate synchronously. Then, under the push of the thread, the threaded rods 103 drive the sliding seat 2 to move. The movement of the sliding seat 2 drives the clamping module 4 on the sliding seat 2 to move, increasing the distance between the two clamping modules 4. With the clamping ability of the clamping module 4, the wire harness located between the two clamping modules 4 is in a straightened state, improving the accuracy during cutting. When the sliding seat 2 moves, it drives the synchronous belt 303 to move through the connecting frame 201. The connecting bolt 202 passes through the synchronous belt 303 and is threadedly connected to the connecting frame 201, further relatively fixing the connecting frame 201 and the synchronous belt 303.

[0027] As Figures 1-2 shown, a guiding frame 304 is fixedly connected to the lower surface of the workbench 1. Rotating rollers 3 are rotatably connected to the inner surface of the guiding frame 304 near the front and rear edges. A conveyor belt 305 is nested on the outer surface of the rotating rollers 3. One end of each rotating roller 3 is in interference fit with a one-way bearing 301. The outer ring part of the one-way bearing 301 is fixedly connected to a synchronous pulley 302. The synchronous belt 303 is meshed with the synchronous pulley 302.

[0028] In this embodiment, during the process of the two clamping modules 4 moving apart, the synchronous belt 303 drives the synchronous pulley 302 to rotate. In cooperation with the one-way bearing 301, at this time, the synchronous pulley 302 rotates alone without driving the rotating roller 3 to rotate. When the distance between the two clamping modules 4 is shortened, the synchronous pulley 302 drives the rotating roller 3 to rotate in cooperation with the one-way bearing 301, so that the conveyor belt 305 runs. During the process of the clamping module 4 on the sliding seat 2 resetting after the wire harness is cut, it is discharged along the guide frame 304 in cooperation with the conveyor belt 305, so that the clamping module 4 can not only straighten the wire harness and improve the accuracy of wire harness cutting, but also facilitate the blanking of the wire harness after cutting.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, in order to make up for the problem that it is inconvenient to clamp wire harnesses of different sizes in Embodiment One.

[0031] As Figures 1-4 shown, the clamping module 4 further includes a connecting column 404, a nut 405, a limiting block 406 and a limiting plate 407. Sliding grooves 402 are formed on both side surfaces of the clamping frame 401. Connecting columns 404 are fixedly connected to both side surfaces of the sliding frame 403. The connecting columns 404 penetrate through the sliding grooves 402. A limiting block 406 is nested on the outer surface of the connecting column 404. A nut 405 is threadedly connected to the outer surface of the connecting column 404. A limiting plate 407 is fixedly connected to the inner surface of the sliding frame 403. The upper surface of the lower pressing frame 408 abuts against the limiting plate 407. A fastening bolt 503 is threadedly connected to the bottom surface of the sliding groove 402. A second electric push rod 701 is fixedly connected to the upper surface of the clamping frame 401. The output end of the second electric push rod 701 is fixedly connected to the lower pressing frame 408.

[0032] In this embodiment, for the clamping module 4 on the sliding seat 2, by rotating the fastening bolt 503 so that one end of the fastening bolt 503 contacts the limiting roller 502, the limiting roller 502 can be limited, preventing the limiting roller 502 from rotating when the sliding seat 2 moves, which may lead to poor traction effect of the clamping module 4 on the sliding seat 2. When fixing, start the second electric push rod 701. The output end of the second electric push rod 701 drives the pressing frame 408 and the sliding frame 403 to move downward as a whole. The connecting column 404 cooperates with the limiting block 406 and the sliding groove 402 to limit the downward movement of the sliding frame 403, making the downward movement of the sliding frame 403 more stable. When the pressing column 702 cooperates with the pressing wheel 703 to contact wire harnesses of different sizes, the airbag 7 inside the sliding frame 403 contacts the pressing column 702 with a height difference. As the pressing frame 408 presses downward, the airbag 7 is compressed and applies a downward force to each pressing column 702, making each pressing column 702 closely contact the wire harnesses at the corresponding positions of the limiting roller 502. For the clamping module 4 on the sliding seat 2, it can clamp each wire harness. For the clamping module 4 on the mounting seat 501, start the stepping motor 5. The output end of the stepping motor 5 drives the limiting roller 502 to rotate, enabling the limiting roller 502 to convey the wire harnesses, so as to synchronously convey multiple groups of wire harnesses of different sizes, facilitating subsequent synchronous cutting.

[0033] As Figures 1-4 shown, on the inner side of the cutting seat 6, a cutting table 601 is fixedly connected to the upper surface of the workbench 1. A belt cutter 603 is embedded in the upper surface of the cutting seat 6. A guiding column 602 is fixedly connected to the upper surface of the belt cutter 603. A first electric push rod 604 is fixedly connected to the upper surface of the cutting seat 6. The output end of the first electric push rod 604 is fixedly connected to the belt cutter 603.

[0034] In this embodiment, when cutting the wire harnesses, start the first electric push rod 604. The first electric push rod 604 drives the belt cutter 603 to move downward, enabling the belt cutter 603 to cooperate with the cutting table 601 to complete the cutting of the wire harnesses. The guiding column 602 guides the downward movement of the belt cutter 603, making the downward movement of the belt cutter 603 more stable.
