Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically to an integrated machine for cutting and stripping automotive wire harness terminals. Background Technology

[0002] Automotive wiring harnesses are core components of a vehicle's electrical system, assembled from multiple wires, cables, connectors, terminals, and protective materials (such as tape and corrugated tubing), essentially functioning as the car's "neural network." Their function is to efficiently transmit electrical energy, signals, and data to various electronic devices such as the engine, lights, sensors, and entertainment systems, ensuring the coordinated operation of all vehicle electrical components. Wiring harness design must strictly adhere to circuit layout, using grouping, bundling, and insulation protection to prevent short circuits, wear, or electromagnetic interference, while also withstanding complex operating conditions such as high temperatures and vibrations. Automotive wiring harnesses require processing using integrated cutting and stripping machines during production.

[0003] For example, authorization announcement number CN212462329U discloses a wire harness cutting and stripping machine with an anti-breakage structure, specifically relating to the technical field of wire harness processing equipment. It includes a worktable, a first servo motor, a first rotary wheel, and a second rotary wheel. A second servo motor is fixedly connected to one side of the top of the worktable, and a first servo motor is fixedly connected to the other side of the top of the worktable. An auxiliary structure is fixedly connected to one side of the top of the worktable, a cutting mechanism is fixedly connected to the middle position of the top of the worktable, and a cleaning mechanism is fixedly connected to the other side of the top of the worktable. This invention utilizes a cutting mechanism fixedly connected to the middle position of the top of the worktable. When the wire harness is transferred from the auxiliary structure to the cutting mechanism, a hydraulic cylinder drives a hydraulic telescopic rod and blades to cut and strip it. A protective cover around the machine prevents the operator's hands from contacting the blades, and any falling insulating strips fall into a collection box for easy collection and reuse.

[0004] However, the cutting mechanism of the above-mentioned integrated cutting and stripping machine does not have a wire harness support structure, which makes the wire harness prone to bending in the cutting mechanism, thus affecting the processing of the wire harness; therefore, the market urgently needs to develop an integrated cutting and stripping machine for automotive wire harness terminals to help people solve the existing problems.

[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.

[0023] Please see Figures 1-4 This utility model provides an embodiment of an integrated machine for cutting and stripping automotive wiring harness terminals, comprising a support frame plate 1. Vertical strip openings 102 are provided at both the upper and lower ends of the front face of the support frame plate 1. Cutting plates 3 are provided at the front ends of both strip openings 102. Semicircular grooves 301 are provided at adjacent ends of the two cutting plates 3. Semicircular annular cutters 302 are fixedly installed inside the semicircular grooves 301, and semicircular notches 303 are provided on the semicircular annular cutters 302. Second linkage blocks 4 are fixedly connected to the rear ends of both cutting plates 3. The two second linkage blocks 4 extend through the two strip openings 102 and out of the rear face of the support frame plate 1. Second electrically controlled telescopic rods 1 are fixedly connected to the rear face of the support frame plate 1 at the upper end of the upper strip opening 102 and the lower end of the lower strip opening 102. 05. The telescopic ends of the two second electrically controlled telescopic rods 105 are fixedly connected to the two second linkage blocks 4 respectively. A support block 5 is fixedly connected to the front end face of the support frame plate 1 on one side between the two cutting plates 3. A circular through hole 501 is provided in the middle of the support block 5. By inserting the wire harness into the circular through hole 501 along one side of the support block 5, the wire harness moves to the space between the two cutting plates 3 through the circular through hole 501. The two second electrically controlled telescopic rods 105 synchronously drive the two cutting plates 3 to move relative to each other, so that the two semi-circular annular cutters 302 can accurately cut the wire harness in the circumferential direction. At the same time, the semi-circular notch 303 is designed to avoid completely cutting the wire core. When cutting is required again, the two cutting plates 3 continue to move relative to each other through the second electrically controlled telescopic rods 105, so that the two semi-circular annular cutters 302 can completely cut the wire harness.

[0024] Please see Figure 2 The support frame plate 1 has two second guide rods 106 fixedly connected to the middle of the rear end of the support frame plate 1. The two rear ends of the two second linkage blocks 4 are fixedly connected to guide blocks 401. The upper and lower ends of the middle of the two second guide rods 106 pass through the middle of the guide blocks 401 on both sides of the two second linkage blocks 4. When the second linkage block 4 is raised and lowered, the two guide blocks 401 are moved synchronously to slide along the two second guide rods 106 to ensure the stability of the second linkage block 4 in raising and lowering.

[0025] Please see Figure 1 and Figure 2The support frame plate 1 has rectangular openings 101 on both sides of the middle of the front section. Clamping mechanism side plates 2 are located at the upper and lower ends of the middle of the front ends of the two rectangular openings 101. Rotating rollers 201 are rotatably connected to both sides of the front ends of the clamping mechanism side plates 2. A conveyor belt 202 is connected to both rotating rollers 201. A first linkage block 205 is fixedly connected to the middle of the rear end face of the clamping mechanism side plates 2. The first linkage blocks 205 at the rear ends of both clamping mechanism side plates 2 extend through the rectangular openings 101 and out of the rear end face of the support frame plate 1. First electrically controlled telescopic rods 103 are fixedly connected to the rear end face of the support frame plate 1 at the middle of the upper and lower ends of the rear ends of the two rectangular openings 101. The telescopic ends of the first electrically controlled telescopic rods 103 at both ends are fixedly connected to the two first linkage blocks 205 respectively. The two first electrically controlled telescopic rods 103 synchronously drive the two first linkage blocks 205 to move in a mirror image, thereby causing the two first linkage blocks 205 to synchronously drive the upper and lower clamping mechanism side plates 2 to move in a mirror image, realizing the mirror image movement of the upper and lower conveyor belts 202. The upper and lower ends on both sides of the wire harness cutting position are clamped by the conveyor belts 202 set on the upper and lower clamping mechanism side plates 2 at the front end of the two rectangular openings 101. At the same time, the wire harness is mirrored after being clamped by the upper and lower conveyor belts 202, thereby realizing the conveying and support of the parts of the wire harness located on both sides of the cutting plate 3.

[0026] Please see Figure 2 Each rotating roller 201 is rotatably connected to the clamping mechanism side plate 2 via a rotating shaft 203. A drive motor 204 is fixedly connected to one side of the rear end face of the clamping mechanism side plate 2. The rear end of the rotating roller 201 on one side passes through the clamping mechanism side plate 2 and is fixedly connected to the output shaft of the drive motor 204. The drive motor 204 drives the rotating roller 201 to rotate, thereby causing the rotating roller 201 to drive the conveyor belt 202 to rotate.

[0027] Please see Figure 2 On the rear end face of the support frame plate 1, vertical parallel first guide rods 104 are fixedly connected to both sides of the middle of the rear end of the two rectangular openings 101. The upper and lower ends of the middle of the two first guide rods 104 at the rear end of the rectangular openings 101 pass through the middle sides of the interior of the two first linkage blocks 205 respectively. When the first linkage block 205 is raised and lowered, the middle sides of its interior slide along the two first guide rods 104 respectively, ensuring the stability of the raising and lowering of the first linkage block 205.

[0028] Working Principle: During operation, the automotive wiring harness to be processed is inserted into the circular through-hole 501 from one side of the support block 5, allowing the harness to pass through the support block 5 and extend between the upper and lower cutting plates 3. The two first electrically controlled telescopic rods 103 are activated, synchronously driving the upper and lower clamping mechanism side plates 2 to move towards each other, ensuring that the two sets of conveyor belts 202 firmly clamp both sides of the wiring harness cutting position. The drive motor 204 drives the rotating roller 201 to rotate via the rotating shaft 203, causing the conveyor belts 202 to rotate synchronously, thus achieving stable conveying and support of the wiring harness and preventing bending during processing. When the wiring harness cutting position moves between the two cutting plates 3, the conveyor belts 202 stop rotating, and the two second electrically controlled telescopic rods 105 push the cutting plates 3 towards each other, allowing the semi-circular annular cutter 302 to cut the insulation layer in the circumferential direction of the wiring harness. At this time, the semi-circular notch 303 design avoids cutting the internal wire core. When it is necessary to completely cut the wiring harness, the second electrically controlled telescopic rods 105 continue to advance, causing the semi-circular annular cutter 302 to completely close.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
