[0019] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a pipe fitting welding clamp includes a support 1 and an installation platform 2, which is rotatably mounted on the support. Several positioning components 3, each including a base 31 and a top 32, are disposed on the installation platform. The base has an installation groove 311 for partially inserting the pipe fitting 9, and a crossbar 312 is provided on the base. The top 312 is movably connected to the crossbar and is used to press the pipe fitting 9 when lowered. The installation platform can be rotated to adapt to different installation angles, making it more convenient to use. The positioning components are used to install workpieces; both workpieces are installed using positioning components, and the contact portion is used for welding. The figure shows one workpiece, whose left end face is used to contact another workpiece. The installation platform can be rotated through hinges or other means.

[0020] In this embodiment, as shown in the figure, the mounting groove is a V-shaped groove. This provides better positioning.

[0021] In this embodiment, as shown in the figure, the top head includes a screw 321, which is threadedly connected to the crossbar. The screw rotates to raise and lower itself, thereby clamping the pipe fitting.

[0022] In this embodiment, as shown in the figure, a clamping block 322 is provided at the tail end of the screw. The clamping block is used to contact the pipe fitting and is made of rubber. By using a rubber clamping block to contact the pipe fitting, the possibility of damaging the workpiece surface is reduced.

[0023] In this embodiment, as shown in the figure, the mounting platform includes a rotating shaft 21 and a flange 22. The rotating shaft is rotatably connected to the bracket. The flange has a plurality of indexing holes 221, and the distance from the center of each indexing hole to the axis of the rotating shaft is equal. The bracket has a pin 4, which engages with the indexing holes. After rotating a certain angle, the pin is inserted to fix the rotation and prevents further rotation; the pin can be pulled out to allow rotation.

[0024] In this embodiment, as shown in the figure, the angle between adjacent indexing holes is 30°.

[0025] In this embodiment, as shown in the figure, the bracket is provided with a mounting base 5, the mounting base is provided with a rotatably connected frame 51, the frame is provided with a handle 511, and the frame is provided with a rotatably connected connecting plate 52, the connecting plate being connected to the pin. Manually operating the handle can drive the frame to rotate, and the rotation of the frame will drive the pin. A guide tube is provided at the front end of the mounting base, and the pin portion is located inside the guide tube for easy operation.
