[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1-Figure 2 As shown, the clamping device for welding metal pipe fittings comprises a frame 1, on which a rotating cylinder 3 is mounted, on which a mounting plate 4 is fixed, on which a rotating table the rotating cylinder 3 is mounted, on which a bracket 5 is mounted at one end, and on which a bracket 2 11 is mounted at the other end of the mounting plate 4, on which a clamping assembly for clamping transverse pipe fittings is provided, and on which a L-shaped piece 14 for limiting support of the transverse pipe fittings is detachably mounted. With this structure, the transverse pipe fittings are first placed on two supporting wheels 6 so that one end of the transverse pipe fittings abuts against the L-shaped piece 14, and at the same time, the L-shaped piece 14 can play an auxiliary supporting role for one end of the transverse pipe fittings; on the bracket 2 11, a cylinder 10 is mounted, and on the end of the piston rod of the cylinder 10, a pressing block 9 for pressing the vertical pipe fittings onto the transverse pipe fittings is mounted.

With this structure, when placing the vertical pipe, the movable limit block 12 is extended by the cylinder 2 13, and the vertical pipe is placed on the horizontal pipe and abutted against the movable limit block 12. Then, the pressing block 9 is driven downward by the cylinder 10 to press the vertical pipe onto the horizontal pipe. Finally, the movable limit block 12 is reset outward by the cylinder 2 13.
[0017] The clamping assembly includes two support seats 18, an adjusting seat 16 and a cylinder three 8. The support seats 18 are installed at the lower part of the bracket 5.
