End part adjustable clamping device for large-component assembly welding of aluminum alloy vehicle body

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
