Description

Technical Field

[0001] This utility model relates to the field of vehicle roof assembly technology, and in particular to the composition and manufacturing tooling of vehicle roofs for rail vehicles. Background Technology

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Because the roofs of rail vehicles have different curvatures, tooling is needed to assemble and weld the side beams and roof panels when welding the roof. Due to the differences in various vehicle models, the length, width, and side beam outlines of the roofs are different, which will inevitably lead to the variability of their tooling requirements.

[0004] The assembly and manufacturing of 25G and 25T rail vehicles require corresponding tooling. The roof is characterized by its large size and complex shape. During assembly and welding, accurate positioning and reliable clamping of the skin and internal frame are prerequisites for ensuring product quality. Existing technologies mostly use general-purpose clamps (such as jacks, pressure plates, bolts, etc.) for fixing, which relies on the experience of operators. It is difficult to ensure that the frame and skin fit completely, which can easily lead to assembly gaps and result in large internal stress or welding deformation after welding. Utility Model Content

[0005] The purpose of this utility model is to provide a roof assembly and manufacturing tooling for rail vehicles. The top surface of the roof support mold is provided with an arc-shaped groove for inserting a matching shape of the rail vehicle roof to ensure that the rail vehicle roof is positioned correctly. The shape of the protrusion on the bottom surface of the roof protrusion pressure beam matches the shape of the arc-shaped groove. Under this premise, the lower end of the roof clamping components evenly arranged on the bottom surface of the roof protrusion pressure beam can evenly clamp and position the rail vehicle roof. This solves the technical problem that existing technologies mostly use general-purpose clamps for fixing, rely on the experience of operators, and are difficult to ensure a complete fit between the frame and the skin, which easily leads to assembly gaps and causes large internal stress or welding deformation after welding.

The top of the roof support mold is provided with an arc-shaped groove; A roof support concave mold is provided directly above a roof protrusion pressure beam, and a roof clamping assembly is uniformly assembled on its bottom surface. Support connection components are mounted on the left and right sides of the bottom surface of the roof protrusion pressure beam, on the same side as the top surface of the tooling support seat.

[0007] As a further optimization, in order to provide a platform for installing the roof clamping assembly, the roof protrusion beam includes: A horizontal pressure beam, with an arched pressure beam fixedly assembled in the middle of its bottom surface; The roof clamping assembly is uniformly assembled along the length of the bottom surface of the arched pressure beam; The roof of a rail vehicle is inserted into the arc-shaped groove, and the lower end of the roof clamping assembly abuts against the upper surface of the rail vehicle roof.
