[0021] Refer toFigures 1-3 The utility model provides a pipe fitting machining clamp, including main seat 1, a plurality of screws are threadedly connected on main seat 1, and the setting of the plurality of screws ensures that the overall structure is firm and reliable. A circular mouth 2 is formed in the main seat 1 for the pipe to pass through. The design of the circular mouth 2 takes into account the actual machining requirements, so that the pipe can be easily positioned and fixed in the clamp. A pair of arc-shaped plates 3 is arranged on the main seat 1, and the arc-shaped plates 3 are arranged correspondingly to the circular mouth 2. The arc-shaped plates 3 are arranged to closely fit the outer wall of the pipe, thereby effectively clamping the pipe.

[0022] A driving structure is arranged on the main seat 1 for driving the two arc-shaped plates 3 to move synchronously.

[0023] The driving structure includes two pairs of L-shaped plates 4 fixedly connected to the main seat 1. Two bidirectional lead screws 5 are rotatably connected to the opposite side walls of the two L-shaped plates 4 in the same pair. A sliding rod 6 is fixedly connected to the other pair of L-shaped plates 4. A moving plate 8 is threadedly connected to the bidirectional lead screw 5. The moving plate 8 is vertically slidably connected to the sliding rod 6. A motor 7 is fixed to the L-shaped plate 4 for driving the bidirectional lead screw 5 to rotate. Under the action of the motor 7, the two moving plates 8 can move synchronously relative to or away from each other, thereby clamping or feeding the pipe.

[0024] A mounting piece is arranged on the moving plate 8 for mounting the arc-shaped plate 3.

[0025] The mounting piece includes an insertion plate 9 fixedly connected to the opposite side walls of the two arc-shaped plates 3. A plurality of insertion holes 10 are equidistantly formed in the moving plate 8 for the vertical sliding of the insertion plate 9. The plurality of insertion holes 10 ensure that the insertion plate 9 can stably vertically slide through the moving plate 8 when different arc-shaped plates 3 are replaced. The design of the insertion plate 9 not only ensures the stable connection between the arc-shaped plate 3 and the moving plate 8, but also makes the movement of the arc-shaped plate 3 more smooth. A fixed plate 11 is fixedly connected to the moving plate 8. A rectangular rod 12 is fixedly connected to the fixed plate 11. A limiting plate 13 is slidably connected to the rectangular rod 12.
