Description

Technical Field

[0001] This utility model relates to the field of wire harness stripping technology, specifically to a stripping device for coaxial wire harness processing. Background Technology

[0002] Wire harnesses are wiring components that connect various electrical devices in a circuit, consisting of core wires and an outer casing. The quality of the wire harness directly affects whether the entire electrical equipment can operate normally and safely. This is especially true in the automotive manufacturing process, where the outer protective layer of wire harnesses used in automobiles is relatively thick, making stripping them quite difficult. Traditional stripping methods mostly involve manually cutting the insulation with a knife, or using wire strippers. However, because the surface of the insulation is relatively smooth, the knife may slip, potentially causing injury to the worker's hands. When using traditional wire strippers, one hand needs to control the pliers to clamp the wire harness while pulling it backward. For automotive wire harnesses, due to the hardness of the protective layer, wire strippers lack a force-applying device, making them quite laborious and inconvenient to use. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology in which wire harness stripping is relatively laborious during the automotive process, and to provide a stripping device for coaxial wire harness processing.

[0004] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a stripping device for coaxial cable processing, comprising a stripping pliers body, the stripping pliers body comprising a first handle and a second handle, a support head hinged to the upper part of the first handle and the second handle, a bent portion hinged to the top of the first handle and the second handle via a connecting shaft, a support frame provided above the support head, a cutting module for cutting the cable sheath provided above the connecting shaft, a stripping device for separating the cable sheath provided behind the cutting module, and a force-applying device for pulling backwards provided outside the stripping device.

[0005] Furthermore, the bottom of the support frame is connected to the support head, a limit plate is provided on the outer side of the support frame, and a limit groove is provided in the middle of the limit plate to limit the movement range of the connecting shaft.

[0006] Furthermore, the cutting module includes a lower mold, which is hinged to the connecting shaft. The side of the lower mold is slidably disposed along the length direction of the support frame. An upper mold that cooperates with the lower mold is disposed on the upper part of the support frame. The sides of the upper mold and the lower mold are provided with cutting grooves for cutting wire harnesses.

[0007] Furthermore, the rear end face of the lower mold is provided with a slide table, the slide table is provided with a sliding groove along the length direction, the peeling device includes a lower pressing block slidably disposed inside the sliding groove, the rear end face of the upper mold is provided with a slide rod, and an upper pressing block that cooperates with the lower pressing block is disposed on the slide rod.

[0008] Furthermore, the upper and lower pressure blocks are provided with snap-fit ​​grooves on the side away from the support frame, and the snap-fit ​​grooves and the cutting grooves are on the same vertical plane.

[0009] Furthermore, the force-applying device is a pull rod hinged to the side of the slide table, and the lower part of the pull rod is hinged to the lower pressure block.

[0010] Furthermore, the upper part of the pressing block is provided with a protrusion, and the lower part of the pressing block is provided with a groove that mates with the protrusion.

[0011] The beneficial effects of this utility model embodiment are as follows: The upper part of the lower pressing block is provided with a protrusion, and the lower part of the lower pressing block is provided with a groove that cooperates with the protrusion. When in use, the lower mold drives the slide table and the lower pressing block to move upward, so that the protrusion engages with the groove. Then, the pull rod is pulled backward, which can drive the upper pressing block and the lower pressing block to move backward, thereby pulling the cut wire sheath backward to complete the stripping operation. By using the upper pressing block and the lower pressing block to perform the stripping operation through the pull rod, the operation difficulty is reduced and the operation steps are simplified.

[0019] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] See Figures 1 to 6 This utility model discloses a peeling device for coaxial cable processing, mainly including a peeling pliers body. The peeling pliers body is composed of a first handle 101 and a second handle 102. A support head 1 is hinged to the upper part of the first handle 101 and the second handle 102 to provide a stable support foundation for the entire device. The top of the first handle 101 and the second handle 102 is provided with an inward bending part and is hinged to a connecting shaft 104, so that the handle can move flexibly during operation. A support frame 2 is provided on the upper part of the support head 1. The bottom of the support frame 2 is connected to the support head 1. A limit plate 103 is provided on the outer side of the support frame 2. A limit groove is provided in the middle position of the limit plate 103. The limit groove is used to limit the movement range of the connecting shaft 104 to ensure the stability and accuracy of the device during operation.

[0021] A cutting module for cutting wire sheaths is provided above the connecting shaft 104. The cutting module includes a lower die 201, which is hinged to the connecting shaft 104. The side of the lower die 201 slides along the length of the support frame 2, allowing the lower die 201 to be adjusted in position according to operational requirements. During use, clamping the first handle 101 and the second handle 102 causes the connecting shaft 104 to move the lower die 201 upward under the action of the limiting groove, providing force for cutting the wire harness. The support frame 2 consists of two plates, with a guide groove in the middle for the movement of the lower die 201. The lower mold 201 can only move up and down to ensure stability and accuracy. The upper part of the support frame 2 is provided with an upper mold 202 that cooperates with the lower mold 201. The upper mold 202 is fixedly set on the support frame 2. The sides of the upper mold 202 and the lower mold 201 are provided with cutting grooves 203 for cutting wire harnesses. When the wire harness is inserted into the cutting groove 203, the upper mold 202 is made to cooperate with the lower mold 201 by operating the handle. The lower mold 201 moves upward, so that the cutting groove 203 directly acts on the outer sheath of the wire harness. Under the action of pressure, the insulation of the wire harness can be cut. It is convenient to use and simple to control.

[0022] A stripping device for separating the wire insulation is provided at the rear of the cutting module. The stripping device includes a slide 3 fixedly mounted on the rear end face of the lower mold 201. The slide 3 can move up and down together with the lower mold 201. The slide 3 has a sliding groove along its length. The stripping device includes a lower pressing block 301 slidably disposed inside the sliding groove. The lower pressing block 301 is limited by a limiting rod and can only move inside the sliding groove. A slide rod is provided on the rear end face of the upper mold 202. An upper pressing block 302 that cooperates with the lower pressing block 301 is provided on the slide rod. The upper pressure block 302 and the lower pressure block 301 are provided with a snap-fit ​​groove 305 on the side away from the support frame 2. The snap-fit ​​groove 305 and the cutting groove 203 are on the same vertical plane, and there is no gap between the snap-fit ​​groove 305 and the cutting groove 203, which reduces the amount of protective layer retained when cutting the wire harness. This design ensures that after the cutting is completed, the wire harness can be accurately pressed by the stripping device, and the snap-fit ​​groove 305 is snapped into the inside of the wire harness protective layer, forming a cutting point at the cutting point, which prepares for the subsequent stripping operation and improves the operation effect.

[0023] The outer side of the peeling device is equipped with a force-applying device for pulling backward. The force-applying device is a pull rod 4 hinged to the side of the slide table 3. The pull rod 4 is U-shaped, and the lower part of the pull rod 4 is hinged to the lower pressure block 301. The upper part of the lower pressure block 301 is provided with a protrusion 303, and the lower part of the lower pressure block 301 is provided with a groove 304 that cooperates with the protrusion 303. In use, the lower mold 201 drives the slide table 3 and the lower pressure block 301 to move upward, so that the protrusion 303 engages with the groove 304. Then, pulling the pull rod 4 backward can drive the upper pressure block 302 and the lower pressure block 301 to move backward, thereby pulling the cut wire skin backward to complete the peeling operation.

[0024] During use, the wire harness is first inserted into the cutting groove 203 from the front, and then the first handle 101 and the second handle 102 are clamped. The cutting groove 203 cuts the wire harness. At this time, the protrusion 303 on the lower pressure block 301 engages with the groove 304 to ensure the stability of the lower pressure block 301 in subsequent operations. Then, the pull rod 4 is pulled backward. The pull rod 4 drives the lower pressure block 301 to slide in the sliding groove. At the same time, the upper pressure block 302 moves on the sliding rod to pull the cut wire sheath backward, thus completing the wire harness stripping operation. This improves the efficiency and safety of the stripping operation. Furthermore, during use, one hand can hold the stripped wire in its original state, and the other hand can pull the pull rod 4 backward to complete the stripping operation with both hands, reducing the difficulty of operation and simplifying the operation steps.
