[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0023] Please see Figures 1-4 A wire cutting device for automotive wiring harness production includes a cutting chamber 100, an electric telescopic rod 200 mounted on the top of the cutting chamber 100, and a cutting blade 300 connected to the bottom of the electric telescopic rod 200.

[0024] The cutting chamber 100 is internally equipped with a cleaning component 400, which includes a fixing frame 401 located inside the cutting chamber 100 and fixedly connected to it. A servo motor 402 is mounted on the side of the cutting chamber 100, and a power rod 403 is driven to the side of the servo motor 402. Activating the electric telescopic rod 200 drives the cutting blade 300, which is connected to it, to perform a corresponding cutting operation on the fed wire harness. Simultaneously activating the servo motor 402 drives the power rod 403, which is connected to it, to rotate. The fixing frame 401 has a through-hole fixing slot 404, and a reciprocating lead screw 405 is fixedly connected to the side of the power rod 403. When the power rod 403 rotates, it drives the reciprocating lead screw 405, which is fixedly connected to it, to rotate. A sliding block 406 is mounted on the outer side of the reciprocating lead screw 405. The sliding block 406 is located inside the fixed groove 404 and is slidably connected to the fixed groove 404. A transmission rod 407 is fixedly connected to the side of the sliding block 406, and a cleaning brush 408 is fixedly connected to the side of the transmission rod 407. When the reciprocating lead screw 405 rotates, because the sliding block 406 is mounted on the outer side of the reciprocating lead screw 405 and is slidably connected to the fixed groove 404, it is restricted by the fixed frame 401 through the fixed groove 404. This causes the sliding block 406 to move back and forth on the reciprocating lead screw 405. The sliding block 406 drives the transmission rod 407 fixedly connected to it to move, which in turn drives the cleaning brush 408 fixedly connected to it to move back and forth, thus cleaning the cutting blade 300 that has moved to this position. Furthermore, by using the electric telescopic rod 200 to change the moving speed of the cutting blade 300, different parts of the cutting blade 300 can be cleaned, improving the subsequent cutting effect of the device.

[0025] In use, starting the electric telescopic rod 200 drives the cutting blade 300, which is connected to it, to cut the wire harness. Simultaneously starting the servo motor 402 drives the power rod 403, which is connected to it, to rotate. The power rod 403 then drives the reciprocating screw 405, which is fixedly connected to it, to rotate. Because the sliding block 406 is mounted on the outside of the reciprocating screw 405 and is slidably connected to the fixed groove 404, it is restricted by the fixed frame 401 through the fixed groove 404. This causes the sliding block 406 to move back and forth on the reciprocating screw 405. The sliding block 406 drives the transmission rod 407, which is fixedly connected to it, to move. The transmission rod 407 then drives the cleaning brush 408, which is fixedly connected to it, to move back and forth, thus cleaning the cutting blade 300. By changing the moving speed of the cutting blade 300 using the electric telescopic rod 200, different parts of the cutting blade 300 can be cleaned. Example

[0026] Please see Figures 1-4Based on Embodiment 1, an auxiliary component 500 is provided inside the cutting chamber 100. The auxiliary component 500 includes a hydraulic chamber 501, which penetrates the cutting chamber 100 and is fixedly connected to it. One end of the hydraulic chamber 501 is slidably connected to a force-bearing rod 502 via a spring. When the sliding block 406 moves to the rear end of the inner wall of the cutting chamber 100, it compresses the force-bearing rod 502, causing the force-bearing rod 502 to compress the spring and move into the hydraulic chamber 501. The other end of the hydraulic chamber 501 is slidably connected to a toothed rod 503. When the force-bearing rod 502 compresses the spring and moves into the hydraulic chamber 501, the pressure inside the hydraulic chamber 501 slidably connected to the force-bearing rod 502 increases, driving the toothed rod 503 slidably connected to the hydraulic chamber 501 to move. A fixing member 504 is fixedly connected to the inner wall of the cutting chamber 100. A gear 505 is rotatably connected to the side of the fixing member 504. The gear 505 is located at the top of the rack 503, and the gear 505 and the rack 503 are in a meshing state. An elastic cam 506 is fixedly connected to the side of the gear 505. When the rack 503 moves, it drives the meshing gear 505 to rotate. The gear 505 drives the elastic cam 506 fixedly connected to it to rotate, striking the bottom of the sliding block 406 located there, causing the cleaning brush 408 to vibrate, thereby improving the performance of the cleaning assembly 400.

[0027] In use, based on Embodiment 1, when the sliding block 406 moves to the rear end of the inner wall of the cutting chamber 100, it can squeeze the force rod 502, causing the force rod 502 to squeeze the spring and move into the hydraulic chamber 501. This increases the pressure in the hydraulic chamber 501, which is slidably connected to the force rod 502, and drives the toothed rod 503, which is slidably connected to the hydraulic chamber 501, to move. This causes the toothed rod 503 to drive the gear 505 meshing with it to rotate, and the gear 505 to drive the elastic cam 506 fixedly connected to it to rotate, striking the bottom of the sliding block 406 located there, causing the cleaning brush 408 to vibrate to a certain extent.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
