Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage wire harness processing, in particular to a device for breaking up a shielding layer of a high-voltage wire harness. Background Art

[0002] High-voltage wiring harness is one of the indispensable components inside new energy vehicles. It is mainly used to stably transmit electrical energy, shield external signal interference, and ensure the safe and stable driving of new energy vehicles.

[0003] High-voltage wiring harnesses are usually composed of multiple insulated wires, shielding layers, and cable sheaths. In actual applications, the ends of high-voltage wiring harnesses generally need to have their cable sheaths cut off and their shielding layers turned over to expose the insulated wires, making it easier to connect the subsequent installation interface to other automotive parts.

[0004] The shielding layer can be divided into an aluminum foil shielding layer and a metal wire braided shielding layer. The aluminum foil can be directly cut off, but due to its special structure, if the metal wire braided shielding layer is not cut properly, its overall structure will be destroyed, which will affect the transmission effect of the overall signal transmission. Therefore, it is generally broken up and flipped. In the prior art, manual breaking is generally adopted. This method is not only inefficient, but also the metal wire can easily stab the staff, which poses a great safety risk. Utility Model Content

[0005] In view of this, the utility model provides a high-voltage wire harness shielding layer breaking up device, which aims to mechanically break up the braided shielding layer, improve the breaking up efficiency, reduce the processing safety risk, and ensure the consistency of the product.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A device for breaking up the shielding layer of a high-voltage wire harness comprises a mounting base and a breaking up assembly arranged on the mounting base, characterized in that: the breaking up assembly comprises a tool base plate, a tool cover plate and tools distributed in a circular array between the tool base plate and the tool cover plate; a first positioning hole is opened in the middle of the tool base plate, the tool cover plate is provided with a second positioning hole directly opposite to the first positioning hole, the first positioning hole and the second positioning hole are both used for passing the high-voltage wire harness, the tool cover plate is provided with strip drive grooves, the tool base plate is provided with guide grooves, a support shaft is passed through the tool, and both ends of the support shaft are respectively installed in the strip drive groove and the guide groove, the A guide column located in a guide groove is installed on the tool. Under the joint constraints of the guide column and the support shaft, the tool can slide linearly relative to the guide groove, and the tool is provided with a cutting edge at a position close to the circumferential edge of the first positioning hole; the guide groove is inclined relative to the tangential direction of the first positioning hole, and the strip drive groove is inclined relative to the tangential direction of the second positioning hole; the tool cover is rotatably assembled on the mounting base, and a driving motor for driving the tool cover to rotate is provided on the mounting base; a clamping mechanism is provided on the mounting base, and after the high-voltage wiring harness is passed through the first positioning hole and the second positioning hole, the clamping mechanism is used to fix and clamp the high-voltage wiring harness.

[0008] By adopting the above structure, the high-voltage wire harness can be fixed by the clamping mechanism, and then the drive motor is used to drive the tool cover to rotate. Under the joint constraints of the guide column and the support shaft, the tool can be moved linearly inside the guide groove. Since the guide groove and the strip drive groove are both inclined, the purpose of breaking up the shielding layer of the high-voltage wire harness is achieved by opening and closing the tool obliquely. Compared with traditional manual breaking up, it has a high degree of mechanization and high efficiency, and mechanical processing ensures product consistency.

[0009] As a preferred embodiment, a mounting seat is provided on the tool bottom plate, and the drive motor is fixedly mounted on the mounting seat. The above structure ensures that the drive motor can be fixedly mounted.

[0010] As a preferred embodiment, a synchronous gear is fixedly arranged on the outside of the tool cover, an output gear is mounted on the output end of the drive motor, and the synchronous gear and the output gear are connected via a synchronous belt. The above structure can provide rotational kinetic energy for the tool cover.

[0011] Preferably, the strip-shaped driving groove is an arc-shaped groove. With the above structure, an arc-shaped rotational force can be provided to the tool, ensuring that the tool can move linearly better inside the guide groove.

[0012] Preferably, the clamping mechanism is a symmetrically distributed clamping cylinder fixedly mounted on the mounting base, a limit block is provided at the end of the cylinder rod of the clamping cylinder, the end of the limit block is configured as a semicircular structure, and a sliding groove is provided on the mounting base, and the limit block can slide in the sliding groove. With the above structure, the high-voltage wire harness can be stably clamped by the two symmetrically distributed semicircular structures, and the sliding groove makes the overall structure of the clamping mechanism more compact.

[0013] Preferably, a telescopic cylinder is fixedly arranged on the tool bottom plate, and the cylinder rod of the telescopic cylinder is fixedly connected to the mounting base, and the operation of the telescopic cylinder can drive the breaking assembly to move relative to the mounting base. With the above structure, the shielding layer can be broken up progressively, thereby ensuring that the shielding layer is broken up more completely.

[0014] As a preference, the tool is in the form of an oblique triangular prism structure, and the tools can be stacked on top of each other to form a regular polygonal closed structure. The above structure can make the tool layout more compact.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The high-voltage wire harness shielding layer breaking device provided by the utility model is adopted to clamp the high-voltage wire harness through the clamping mechanism, and then the drive motor is used to drive the tool cover to rotate, and the tool cover drives the tool to move inside the movable groove, so that the tool is opened and closed as a whole, thereby breaking up the high-voltage wire harness shielding layer. Compared with the traditional manual breaking up, the mechanization degree is high, the breaking up efficiency is faster, and the harm to personnel is avoided. In addition, the mechanized processing also ensures the uniformity of the product.

[0017] 2. Through the design of the telescopic cylinder, the tool can move relative to the high-voltage wire harness when the high-voltage wire harness shielding layer is being scattered, ensuring that the high-voltage wire harness shielding layer has sufficient scattered length.

[0025] The utility model is further described below in conjunction with embodiments and drawings.

[0026] like Figures 1 to 3 As shown, a high-voltage wire harness shielding layer breaking device includes a mounting base 1 and a breaking component A mounted on the mounting base 1. The breaking component A includes a tool base plate 2, a tool cover plate 3, and a tool 4 disposed between the tool base plate 2 and the tool cover plate 3. In this embodiment, a total of ten tools 4 are installed, and the ten tools 4 are distributed between the tool base plate 2 and the tool cover plate 3 in a circular array.

[0027] like Figures 3 to 5 As shown, a first positioning hole 2a is provided in the middle of the tool base plate 2, and a second positioning hole 3a is provided on the tool cover plate 3, which is directly opposite to the first positioning hole 2a. Both the first positioning hole 2a and the second positioning hole 3a are used to pass through the high-voltage wiring harness, and the tool 4 is arranged in an array around the first positioning hole 2a. Strip drive grooves 3b are distributed on the tool cover plate 3, guide grooves 2b are distributed on the tool base plate 2, and a support shaft 4a is passed through the tool 4. The two ends of the support shaft 4a are respectively installed inside the strip drive grooves 3b and the guide grooves 2b. In this embodiment, the support shaft 4a is fixedly passed through the tool 4 by integral molding or welding. A guide column 4b is also formed on the side of the tool 4 close to the guide tool base plate 2. Under the joint constraints of the guide column 4b and the support shaft 4a, the tool 4 can slide linearly relative to the guide groove 2b, and a cutting edge 4c is formed on the tool 4 near the circumferential edge of the first positioning hole 2a. In this embodiment, the guide groove 2b is arranged obliquely relative to the tangential direction of the first positioning hole 2a, and the strip-shaped driving groove 3b is arranged obliquely relative to the tangential direction of the second positioning hole 3a.

[0028] like Figure 1 and Figure 2 As shown, the tool cover plate 3 is rotatably mounted on the mounting base 1, and the mounting base 1 is provided with a driving motor 5 for driving the tool cover plate 3 to rotate. The mounting base 1 is also provided with a clamping mechanism 6, and after the high-voltage wire harness is passed through the first positioning hole 2a and the second positioning hole 3a, the clamping mechanism 6 can fix and clamp the high-voltage wire harness.

[0029] Combined with the above structure, the working principle of the high-voltage wire harness shielding layer loosening device is as follows: after the high-voltage wire harness is passed through the first positioning hole 2a and the second positioning hole 3a, the driving motor 5 drives the tool cover 3 to rotate, and under the guidance of the support shaft 4a and the strip drive groove 3b, the inner side of the tool 4 slides linearly relative to the guide groove 2b. When the cutting edge 4c of the tool 4 acts on the surface of the high-voltage wire harness shielding net, the tool 4 slides further downward relative to the guide groove 2b, and the high-voltage wire harness shielding net can be loosened through the cutting edge 4c.

[0030] With this design, the high-voltage wire harness shielding net is scattered by driving the tool 4 to slide in the guide groove 2b by the driving motor 5. Compared with the traditional manual operation, the mechanization degree is high and the efficiency is fast. The mechanized processing avoids injuries to personnel and ensures the consistency of the product.

[0031] In this embodiment, the tool 4 is in the form of an oblique triangular prism structure, and each tool 4 can be stacked on top of each other to eventually form a closed regular polygonal cutting surface. By sliding each tool 4 obliquely in the guide groove 2b, it can be ensured that the outer surface of the shielding layer can be acted on by the tool 4. The oblique triangular prism structure makes the overall structure more compact after the tools 4 are stacked.

[0032] like Figure 6 As shown, a synchronous gear 7 is fixedly installed on the outside of the tool cover plate 3 by bolts, an output gear 8 is sleeved on the output end of the drive motor 5, and the synchronous gear 7 and the output gear 8 are connected by a synchronous belt 9, so as to ensure the rotation power of the tool cover plate 3. In this embodiment, a mounting seat 2c is formed on the tool base plate 2, and the drive motor 5 is fixedly installed on the mounting seat 2c by bolts.

[0033] like Figure 7 As shown, in this embodiment, the clamping mechanism 6 is a symmetrically distributed clamping cylinder, and the clamping mechanism 6 is fixedly installed on the mounting base 1 by bolts. A limit block 10 is fixedly installed at the end of the cylinder rod of the clamping cylinder by bolts. The end of the limit block 10 away from the cylinder rod is constructed into a semicircular structure. Through the two symmetrical semicircular structures, the high-voltage wire harness can be firmly clamped, which can effectively prevent the high-voltage wire harness itself from being offset when the shielding layer of the high-voltage wire harness is scattered, thereby affecting the scattered effect. A movable groove 1a is also provided on the mounting base 1, and the limit block 10 can slide in the movable groove 1a. The design of the movable groove 1a makes the overall structure of the clamping mechanism 6 more compact.

[0034] In this embodiment, the drive motor 5 adopts a forward and reverse switching motion, so that the tool 4 can continuously slide back and forth inside the guide groove 2b, and the high-voltage wire harness shielding layer is scattered back and forth by the tool 4, ensuring that the high-voltage wire harness shielding layer is scattered more thoroughly. In this embodiment, the strip drive groove 3b is an arc groove. In addition to providing a circumferential force to the tool 4, so that the tool 4 can slide better in the guide groove 2b, the strip drive groove 3b also provides a buffer formation for the tool 4, which can ensure that when the rotation direction of the drive motor 5 changes, the sliding direction of the tool 4 will not change immediately, which can effectively prevent the uninterrupted back and forth movement of the tool 4 from causing the support shaft 4a to break.

[0035] like Figure 1 and Figure 2 As shown, a telescopic cylinder 11 is fixedly installed on the tool base plate 2 by bolts, an "L"-shaped support plate 12 is fixedly installed on the mounting base 1 by bolts, and the cylinder rod end of the telescopic cylinder 11 is fixedly installed on the support plate 12 by bolts. By driving the telescopic cylinder 11 to operate, the breaking component A can be moved relative to the mounting base 1, thereby realizing the progressive breaking of the high-voltage wire harness shielding layer. In this embodiment, a guide rod 13 is also provided between the mounting base 1 and the breaking component A, and a linear bearing 14 is also fixedly installed on the breaking component A by bolts, so as to facilitate smoother sliding of the breaking component A relative to the mounting base 1.

[0036] Structure The above structure, the workflow of the utility model is as follows:

[0037] The high-voltage wire harness is passed through the first positioning hole 2a and the second positioning hole 3a, and fixed by the clamping mechanism 6. The driving motor 5 continuously performs forward and reverse motions to drive the tool 4 to move back and forth inside the guide groove 2b, so that the cutting edge 4c of the circumferentially distributed tool 4 rubs the shielding layer of the high-voltage wire harness back and forth, and then cooperates with the telescopic cylinder 11 to progressively control the movement of the scattering component A relative to the mounting base 1 to ensure that the shielding layer of the high-voltage wire harness has sufficient rubbing length.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
