Abstract
The invention discloses a separated type match-welding ring for butt welding of thin walled cylinders and solves the problem that a match-welding ring cannot be taken down after butt joint circular welding of two existing thin walled cylinders. The separated type match-welding ring comprises four crescent plates and two sliding trapezoidal blocks, wherein an upper left crescent plate (1), an upper sliding trapezoidal block (6), an upper right crescent plate (2), a lower right crescent plate (4), a lower sliding trapezoidal block (7) and a lower left crescent plate (3) form a circular match-welding ring, guide long holes (11) are formed in all crescent plates, sliding locating pins on the sliding trapezoidal blocks and moving blocks formed by fan-shaped push plates are arranged in the guide long holes (11), and a scissor jack pushes the upper and lower sliding trapezoidal blocks to unfold the four crescent plates to form the circular match-welding ring. The separated type match-welding ring is assembled into the two thin walled cylinders and can be conveniently disassembled from the two thin walled cylinders; not only can roundness correction be performed to openings of casings, but also the butt joint concentricity of the casings of the two butt joint thin walled cylinders is directly guaranteed.
