Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a tooling for painting fiberglass head covers for rail vehicles. Background Technology

[0002] Currently in the rail vehicle industry, when painting fiberglass head covers of rail vehicles, without tooling or vehicle body support, the fiberglass head covers may deform due to uneven pressure, especially near openings such as windows and vehicle body joints. For fiberglass head covers that are painted and then bonded and installed, using integrated painting and transport tooling allows the head covers to be transferred from the fiberglass production workshop to the final assembly workshop without changing tooling, ensuring that the fiberglass head covers are supported by tooling throughout the entire process from production to final assembly.

[0003] The fiberglass helmet has a volume of approximately 18m. 3 Weighing approximately 450kg, this integrated painting and transport tooling must consider both the safety of the transportation process, such as reducing the height of the tooling to avoid a high center of gravity, and the feasibility of the painting process, such as requiring protective work inside the headgear before painting, ensuring that the tooling does not obstruct the painting surface, and limiting the painting operation space.

[0076] In this embodiment of the community, the support frame and supporting structure are used to effectively avoid deformation when transferring the fiberglass headgear, while also ensuring that the tooling does not obstruct the working space for grinding and painting, thus meeting the actual work requirements.

[0077] Furthermore, the connecting bracket 4 also includes reinforcing ribs 44;

[0078] The reinforcing ribs 44 are arranged along the length of the first vertical plate 40, the first horizontal plate 41, and the second horizontal plate 42 on the inner side of the first vertical plate 40, the first horizontal plate 41, and the second horizontal plate 42.

[0079] Furthermore, the painting fixture also includes:

[0080] Elevated spraying fixture base 5 is installed at the bottom of the spraying fixture base 3;

[0081] The bottom of the height-adjustable paint spraying fixture base 5 is symmetrically provided with multiple second universal wheels 50.

[0082] Furthermore, the tooling support frame 1 includes:

[0083] The main frame 10, the paint protection floor 2 and the paint tooling base 3 are arranged at intervals from top to bottom at the bottom of the main frame 10;

[0084] Structural reinforcement support plate 11 is disposed inside the main frame 10;

[0085] Multiple connecting brackets 4 are disposed on the main frame 10.

[0086] As shown in the attached diagram of the instruction manual. Figure 1 As shown, this fixture mainly consists of four parts. The fixture support frame 1 measures 3.3m * 2.5m * 3m (length * width * height) and is made of welded carbon steel square tubing to ensure sufficient structural strength. Two forklift slots are provided at the bottom of the fixture support frame 1. The forklift forks are inserted into these slots, allowing for easy transport of the fixture support frame 1 and easy assembly / disassembly of the fixture support frame 1, the painting fixture base 3, and the extended painting fixture base 5.

[0087] The bottom of the spray painting fixture base 3 and the height-adjustable spray painting fixture base 5 is equipped with four feet and four casters with built-in brakes, which can achieve stable placement and flexible movement of this fixture.

[0088] Paint-spraying protective floor 2 is a composite material made of aluminum plates and plywood bonded together. This material is strong, slip-resistant, and not easily deformed. Before painting, workers can stand on the protective floor to protect the unpainted areas inside the hood.

[0089] The spray painting fixture base 3 measures 3.3m x 2.5m x 0.3m (length x width x height) and is constructed from welded carbon steel square tubing. The upper part is bolted to the main frame's feet, while the lower part is fitted with four self-braking casters. Once the fixture is transported to the spray painting station, locking the braking mechanism ensures stable placement and simultaneously raises the headgear by 30mm, creating more space for spraying the lower beam of the headgear.

[0090] The structural reinforcement support plate 11 is specifically a trapezoidal front connecting bracket for painting, which is bolted to the front adhesive bracket of the hood, and is relatively close to the painting surface in the area of ​​the front adhesive bracket. To ensure painting quality, the connecting bracket needs to be designed to be at least 150mm away from the surface to be painted, so as to ensure that the painting angle and distance meet the construction requirements. To prevent the hood from tilting forward, the support strength of the connecting bracket also needs to be ensured. For this purpose, a trapezoidal front connecting bracket with reinforcing ribs is designed to support the hood at the front to prevent it from tilting forward, and together with the rear connecting bracket 4, they maintain the center of gravity of the fiberglass hood.

[0091] In summary, the easily detachable raised base for painting can elevate the fiberglass hood during installation, creating space for painting the lower beam; after removal, it can lower the center of gravity of the hood, ensuring its safety during transportation; the trapezoidal front connecting bracket for painting ensures support strength while creating space for painting the area of ​​the front support frame of the hood.
