[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a device for turning the end of a welded pipe into a full circle. After the welded pipe body is placed inside the front clamp assembly and the rear clamp assembly, the welded pipe body is continuously pushed so that one end of the welded pipe body abuts against the inner wall of the welded pipe groove. At this time, the pressed pressure cover will move the thin plate, thereby extending the water spray pipe, allowing the horizontal water spray pipe to move out from the inside of the L pipe groove. Then, coolant can be sprayed onto the inner wall of the welded pipe body. At this time, the threaded rod will bring the movable connecting rod to the right end of the welded pipe body, and the electric telescopic rod B will gradually extend and bring the inner full circle assembly to the right end of the welded pipe body. Then, the motor and the motor B are started at the same time to rotate the active roller and the disc. When the sliding rod inside the disc starts to move, each group of slide plates will be fully extended and fit to the inner wall of the welded pipe body. Then, the rotation speed of the driving rod is increased to start turning the inner wall of the welded pipe body. The outer diameter of the welded pipe body is driven by the turning tool clamped inside the lathe tool holder and the rotation of the active roller to drive the welded pipe body itself to rotate. During turning, the right side of the welded pipe body is beginning to turn a full circle. During turning, the coolant in the reservoir tank will be respectively infused into the long pipe and the water spray pipe, thereby cooling the turning part. Finally, when turning the other end, move the other end of the welded pipe body out of the welded pipe groove. At this time, as the electric telescopic rod B and the movable connecting rod move to the other end of the welded pipe body, turning a full circle can begin. At this time, coolant is still retained on the inner wall of the welded pipe body, so the inner full circle component can also scrape up the coolant during grinding. The external long pipe is still spraying coolant on the other side of the welded pipe body, so the turning position can still be cooled when turning the inner and outer diameters. Finally, when the electric telescopic rod B is fully retracted, the fixed plate and the magnetic block B will push the L slider to move, allowing the L plate B to move upward along the inclined T-slot, thereby causing the welded pipe body to tilt and discharge the internal debris and coolant, thereby improving the processing efficiency of the welded pipe body.

A gear 36 is arranged between the L plate A37 and the thin plate 38, and the gear 36 is rotatably connected to the bottom of the empty groove 1933. The gear 36 is meshed with the rack 381, and a thick plate 39 is slidingly arranged on the outer surface of the thin plate 38. The pressure cover 383 is squeezed by the movement of the welding pipe main body 2, so that the thin plate 38 moves along with it. As the thin plate 38 moves, the gear 36 rotates, so that the water spray pipe 34 also moves along, so that one group of the water spray pipes 34 is extended, and when the welding pipe main body 2 is separated from the welding pipe groove 19, the tension spring 382 will release the tension, thereby driving the thin plate 38 and the water spray pipe 34 to reset.

[0045] A through groove 391 is opened on one side of the thick plate 39, and an inclined plate A392 is fixedly installed at the bottom of the through groove 391. The inclined plate A392 and the inclined groove 384 are slidably arranged, and the thick plate 39 and the short groove 1932 are slidably arranged. The inclined plate A392 can make the thin plate 38 move horizontally while driving the thick plate 39, so that the thick plate 39 can block one group of water spray pipes 34 inside the L pipe groove 1935, thereby protecting the entire water spray pipe 34.

[0046] Working principle: when the welding pipe body 2 needs to be turned into a full circle, after the arc-shaped clamping plates 4215 of the front clamping assembly 41 and the rear clamping assembly 42 are separated, the welding pipe body 2 is placed on the surface of the driven roller 4218, and then the electric telescopic rod C4212 is started to make the center of the welding pipe body 2 and the center of the inner full circle assembly 5 on the same horizontal line, and then the welding pipe body 2 is pushed to make the left end of the welding pipe body 2 inserted into the welding pipe groove 19. With the entry of the left end of the welding pipe body 2, the spring rod 1941 and the outer clamping block 1942 can further align the center of the welding pipe body 2 with the center of the inner full circle assembly 5. After the welding pipe body 2 is fixed by the clamping component 4 and the outer clamping block 1942, the electric telescopic rod B16 is brought to the welding pipe main body with the inner full circle assembly 5. The right end of the welding pipe body 2 is moved to the right end of the welding pipe body 2, and the motor A11 is started at the same time to make the threaded rod 13 bring the movable connecting rod 14 to the right end of the welding pipe body 2, and then the motor B51 is started to make the disc 512 rotate. As the disc 512 rotates, the slide bar 565 in the expansion groove 513 will move, so that the slide plate 562 moves and extends until the honing bar 564 reaches the inner wall of the welding pipe body 2, and the speed of the motor B51 can be increased, so that the honing bar 564 can turn the inner diameter of the welding pipe body 2, and the movable connecting rod 14 clamps the turning tool into the lathe tool holder 145, and then the motor 423 is started to make the active roller 4216 rotate with the welding pipe body 2, so that the lathe tool holder 145 with the turning tool can turn the outer diameter of the welding pipe body 2. When the left end of the body 2 is fixedly connected to the inner wall of the welding pipe groove 19, the pressure cover 383 will be squeezed and pushed by the left end of the welding pipe body 2, so that the thin plate 38 moves. As the thin plate 38 moves, the rack 381 on one side of the thin plate 38 will rotate the gear 36, and the rotation of the gear 36 will drive the L plate A37 to move, and the L plate A37 will drive the horizontal water spray pipe 34 to move. The moving belt of the thin plate 38 can drive the thick plate 39 to move vertically, opening one end of the L pipe groove 1935, so that the horizontal water spray pipe 34 can be extended. As the water spray pipe 34 is extended to the right position, the liquid storage tank 3 begins to inject coolant into the long tube 32 and the water spray pipe 34. The coolant sprayed from the long tube 32 is directly sprayed to the turning position, while the water spray pipe 34 sprays The coolant that comes out flows to the turning position to cool it. When the left end of the pipe mouth of the welding pipe body 2 is turned, the left end of the welding pipe body 2 can be separated from the welding pipe groove 19. At this time, the liquid storage tank 3 also stops infusing, and the pressure cover 383 is no longer squeezed by the welding pipe body 2. The tension spring 382 will bring the thick plate 39, the water spray pipe 34, and the thin plate 38 to reset, so that the horizontal state The water spray pipe 34 is retracted into the L pipe groove 1935, thereby protecting the water spray pipe 34. At this time, the electric telescopic rod B16 and the movable connecting rod 14 can be moved to the right end of the welding pipe body 2 respectively, and the right end pipe mouth is turned. At this time, the inner diameter of the welding pipe body 2 still has coolant remaining, and the long tube 32 is equipped to continuously spray coolant. When the right end port of the welding pipe body 2 is turned,The turning position can still be cooled down. After the turning of the pipe ends is completed, the electric telescopic rod B16 can be fully retracted, and the fixed plate 54 and the magnetic block B55 can pass through the rectangular groove 197 and the magnetic block A4224 in detail, driving the L slider 4222 to move. As the L slider 4222 moves, the inclined plate B4221 will move along the inclined T groove 4226, allowing the L plate B422 to rise with the outer frame 421. As the outer frame 421 rises, the welded pipe body 2 will be in an inclined state. At this time, the welded pipe body 2 in an inclined state will pour all the internal debris and coolant into the discharge trough A15 for discharge, thereby improving the processing efficiency of the welded pipe body 2.
