Technical scheme: for solving the problems of the technologies described above, of the present invention a kind of be applicable to pressure vessel shell ring be welded and fixed fixture, comprise stiff end outer shroud, stiff end inner ring, movable end outer shroud and movable end inner ring, stiff end wheel plate is equipped with for support fixed end inner ring in described stiff end, movable end wheel plate is equipped with for support movable end inner ring in described movable end, described stiff end inner ring is fixed with axial adjusting lever, described movable end inner ring center be provided with adjusting lever movement vertically can be spacing guide cylinder, at stiff end outer shroud, stiff end inner ring, movable end outer shroud and movable end inner ring are respectively equipped with several stiff end outer shroud adjusting bolts, stiff end inner ring adjusting bolt, movable end outer shroud adjusting bolt and movable end inner ring adjusting bolt, the corresponding contrary distribution of head of stiff end outer shroud adjusting bolt and stiff end inner ring adjusting bolt, the corresponding contrary distribution of head of movable end outer shroud adjusting bolt and movable end inner ring adjusting bolt.
As preferably, described stiff end wheel plate and movable end wheel plate are all uniformly distributed several scalloped recess, and stiff end inner ring adjusting bolt and movable end inner ring adjusting bolt are positioned at scalloped recess.
As preferably, described axial adjusting lever is screw rod, and guide cylinder inwall is provided with screw thread.
As preferably, described axial adjusting lever is smooth shaft, and guide cylinder is provided with the locking device of locking smooth shaft.
As preferably, described locking device is clamping screw, and in clamping screw precession guide cylinder, compression axis is to adjusting lever.
Beneficial effect: of the present invention be applicable to pressure vessel shell ring be welded and fixed fixture, pressure vessel cylinder is positioned between inner ring and outer shroud, adjustment in use bolt is fixed pressure vessel cylinder, for different-diameter, the pressure vessel of different-thickness laterally docks with circular weld and welds, replace before traditional spot welding method carries out weldering and fix, accurately weld gap can be controlled by reversely rotating shell ring, shell ring is prevented to be subjected to displacement in welding process and the problems such as post welding distortion, structure is simple, rapidly and efficiently, effectively can prevent the welding deformation of pressure vessel transverse direction and circular weld in welding process, and improve welding efficiency and the welding quality of pressure vessel.
