[0059] Preferably, the tooling bracket 1 of this embodiment includes a quadrilateral bottom frame; a square tube 104 connected to the quadrilateral bottom frame, wherein the upper ends of two square tubes 104 located on the same side of the quadrilateral bottom frame are connected to each other to form a triangular side bracket; and a round tube 103 connected between the triangular side brackets on both sides;

[0060] A wiring protection tube 101 is sleeved on the circular tube 103 ; and a quadrilateral bottom frame is used to place a material collection box 102 .

[0062] This embodiment further defines the structure of the tooling bracket 1. Its bottom is a quadrilateral frame, with two triangular side brackets on either side, each supported by two square tubes 104. These square tubes 104 are primarily used to connect to the aforementioned thermal cutter bracket assembly 2, hot air gun bracket assembly 3, and document display assembly 4. The upper portion of the tooling bracket 1 in this embodiment comprises a detachable circular tube 103, on which is mounted a wiring protection tube 101. This tube 103 can rotate around the tube to facilitate wiring harness retraction. Furthermore, a material collection box 102 is provided at the bottom of the tooling bracket 1 to store materials from the vehicle.

[0063] Preferably, the thermal cutting machine support assembly 2 of this embodiment includes:

[0064] A thermal cutter support base 201 connected to the square tube 104 has a thermal cutter support base groove at the bottom thereof that can accommodate the square tube 104.

[0072] The hot air gun pressing structure 302 is assembled at the long hole with the hot air gun support base 301 through locking bolts and locking nuts on both sides.

[0073] This embodiment further defines the structures of the thermal cutter support assembly 2 and the hot air gun support assembly 3. Since conventional thermal cutters and hot air guns have similar structures, the thermal cutter support assembly 2 and the hot air gun support assembly 3 of this embodiment are substantially identical. This embodiment uses the thermal cutter support assembly 2 as an example for further explanation and description.

[0074] The thermal cutter support assembly 2 of this embodiment primarily comprises a thermal cutter support base 201 and a thermal cutter clamping structure 202. The bottom of the thermal cutter support base 201 of this embodiment has a thermal cutter support base recess that accommodates a square tube 104. Once inserted into the recess, the square tube 104 is secured to the square tube 104 via four thermal cutter support base mounting bolts 203. The thermal cutter is placed within a groove on the front side of the thermal cutter support base 201 and secured to the thermal cutter support base 201 by the thermal cutter clamping structure 202. The thermal cutter clamping structure 202 of this embodiment is adjustable via a slot provided in the thermal cutter support base 201. This facilitates operator control of the thermal cutter's handle and allows the thermal cutter to be secured to the thermal cutter support base 201, preventing it from being too close to the wiring harness and the risk of damaging it. Similarly, the principles of the hot air gun support assembly 3 are similar to those of the thermal cutter support assembly 2 and will not be further described.

[0075] Preferably, the file board folder assembly 4 of this embodiment includes:

[0076] Kanban holder base 401; and

[0077] The kanban clamp connecting plate 403 is provided on the back of the kanban clamp base 401. The space between the two kanban clamp connecting plates 403 is the embedding space of the square tube 104.

[0078] The square tube 104 is connected to the kanban clamp connecting plate 403 via the kanban clamp base mounting bolts 402;

[0079] Support parts are provided at the upper and lower ends of the front side of the signboard holder base 401, and there is a space between the two support parts for placing the protection standard card.

[0080] In order to facilitate operators to check the protection standard card when cutting materials, this embodiment integrates a file kanban clip assembly 4 in the tooling bracket 1, which includes a kanban clip base 401 and a kanban clip connecting plate 403, wherein the two kanban clip connecting plates 403 are connected to the square tube 104 through the kanban clip base mounting bolts 402, and the upper and lower ends of the front side of the kanban clip base 401 form a protruding support part, and the protection standard card can be placed on the kanban clip base 401 using the support part.

[0081] During operation, first insert the wiring protection tube 101 onto the round tube 103, place the materials on the vehicle into the material collection box 102, then fasten the thermal cutter support base 201 to the square tube 104 using four M8*70mm bolts. Use two M6*30mm bolts to assemble the thermal cutter clamping structure 202 onto the support base and pre-tighten it. Place the thermal cutter into the slot of the thermal cutter support base 201. When in use, press down on the clamping structure. The clamping structure of this embodiment can be designed to be linked to the switch, or it can simply constrain the thermal cutter and manually operate the switch. Regardless of the design, the thermal cutter can be kept away from the wiring protection tube 101 to avoid damaging the wires. Similarly, the above-mentioned hot air gun bracket assembly 3 is set on the other side, and finally the kanban clamp base is installed.

[0082] In the above technical solution, the utility model provides a high-speed train in-car wiring auxiliary device, which has the following beneficial effects:

[0083] The auxiliary device of this utility model integrates the wiring protection tube 101, which was originally stacked on the ground, onto the tooling bracket 1. This allows multiple people to work simultaneously during protection, eliminating waiting and improving work efficiency. The thermal cutter bracket assembly 2 and the hot air gun bracket assembly 3 are used to store the thermal cutter and hot air gun respectively, away from the wiring harness to avoid wire damage.

[0084] When the auxiliary device of the present invention is used to protect various parts, the protection can be measured and cut directly on the tooling bracket 1. The produced protection length table is plastic-sealed and fixed on the tooling bracket 1. When cutting, the material can be cut while looking at the table to avoid waste of materials.

[0085] When ordinary mesh pipe protection is prepared under the auxiliary device of the present invention, materials are loaded and unloaded on the tooling bracket 1 to avoid hot knife damage to the wire. The original protection is separated from the material, and the material is placed in the material collection box 102 on the tooling for easy access, thereby standardizing the work site.

[0086] After using the device of the utility model, the time is shortened from the original 8 hours to 5 hours. Now the wiring protection efficiency of this kind of wiring harness protection tooling for each vehicle is increased by more than 60%. According to the daily output of 4 vehicles, the wiring protection link in the vehicle can save 12 hours of time every day, standardize the work site, reduce the hidden dangers of wire damage, improve work efficiency, reduce the labor intensity of operators, and reduce material loss according to the protection of the board.

[0087] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
