The invention discloses an end part adjustable clamping device for the large-component assembly welding of the aluminum alloy vehicle body, and relates to the technical field of auxiliary tools for rail passenger car aluminum alloy vehicle body assembly welding. The end part adjustable clamping device comprises an end clamping module, an inclination angle adjustable base and an inclination angle locking module. The included angle of the end part adjustable clamping device and the horizontal plane is continuously adjustable, the end part adjustable clamping device can better adapt to the inclination angle types of different end structures of various vehicle body large parts, therefore, the matching types and styles of upper clamping blocks, lower clamping blocks and lateral jacking blocks matched with different end part structures of various types vehicle body large parts are remarkably reduced, the selecting matching efficiency during replacement of the clamping blocks is improved, thedesign type and the face type machining precision of the clamping blocks are reduced, the manufacturing difficulty and the occupied storage space of the clamping blocks are reduced, and the production benefit is improved.
Description
technical field [0001] The invention relates to the technical field of auxiliary tooling for assembly and welding of aluminum alloy car bodies of rail passenger cars, in particular to an adjustable end clamping device for assembly and welding of large parts of aluminum alloy car bodies. Background technique [0002] In the field of rail vehicle manufacturing, the accurate positioning of fixtures in the product manufacturing process ensures product quality, facilitates the assembly of workpieces, and improves labor efficiency. Therefore, fixtures have been widely used in the manufacturing industry. However, there are many types of rail vehicles, and there are large differences in vehicle types and dimensions, such as figure 1 As shown, the middle section of the large car body part 12 is a planar structure with a small curvature, but the end structures on both sides are arc-shaped, and the dimensional parameters of the arc are different. Therefore, the large car body parts of ...
