The push rod 37 pushes the inclined surface pushing part to move the side fixing seat 35, and the side fixing seat 35 tightly fixes the circumferential surface of the processing turntable 28.

[0028] The working principle is as follows: The workpiece is fixed through the positioning mechanism. It should be noted that both ends of the workpiece are fixed through the positioning mechanism. On the circumference of the workpiece, there may be a communicating pipe. The communicating pipe and the main pipe may be perpendicular to each other or form an angle. During installation, the angular position of the pipe can be positioned, that is, the position detector extends into the inside of the pipe to detect the wall position, and then the angular orientation of the workpiece can be adjusted through the positioning structure.

[0029] When fixing the workpiece, the motor two 4 works, the lead screw two 5 rotates, and the positioning slide 6 can be moved. The angle motor 7 can drive the turntable 8 to rotate to drive the workpiece to rotate. By controlling the motor 13 to work, the gear disk 12 rotates, causing the connecting gear 11 and the clamping lead screw 10 to rotate, and then driving the clamping rod 9 to move radially. The inner side of the workpiece is supported and fixed by the clamping rod 9 to complete the fixed installation.

[0030] Further, during machining, the motor one 2 controls the belt one 3 to work, causing the machining slide 19 to move. At the machining position, the lifting motor 20 works, and the lifting guide rod 21, the lifting lead screw 22, and the machining slide 19 move, that is, the height is adjusted. When machining the inner wall of the connecting pipe, the machining oil cylinder 32 controls the machining part 33 to extend into the pipe. The position motor 30 works, the position lead screw 29 rotates, and the position slide 31 moves, that is, the radial position is adjusted to make the machining part 33 contact the inner or outer side of the pipe. At this time, the workpiece is in a fixed state. The machining motor 26 works, and the machining turntable 28 rotates for thread machining. When machining the inclined pipe, the flipping motor 24 controls the flipping frame 25 to flip the angle so that the feeding direction of the machining part 33 is parallel to the axis of the inclined pipe, and then the machining is completed.

[0031] Further, the end of the workpiece can be machined. Specifically, one of the positioning mechanisms releases the clamping of the end of the workpiece. The motor three 14 works, and the belt three 15 drives the support slide 16 to move, that is, to support the area of the end of the workpiece where the fixation is released. That is, the support roller 18 is controlled by the support oil cylinder 17 for support. The machining mechanism is controlled to move to the end of the workpiece, and then the flipping frame 25 is controlled to flip so that the machining part 33 faces the end of the workpiece. At this time, the other positioning mechanism drives the workpiece to rotate while the machining part 33 is fixed to machine the inner or outer side of the end of the workpiece. Further, during end machining, the end fixing seat 38 and the push rod 37 are controlled to move by the fixed oil cylinder 34. The end fixing seat 38 presses and fixes the end of the machining turntable 28. The push rod 37 pushes the side fixing seat 35 so that the side fixing seat 35 presses and fixes the circumferential surface of the machining turntable 28, and then the machining turntable 28 is fixed. When the workpiece rotates, the machining turntable 28 is fixed, and the machining oil cylinder 32 controls the machining part 33 to feed to complete the machining. When machining the other end of the workpiece, the above process is adopted, and the clamping end of the workpiece by the positioning mechanism is changed.
