[0048] The implementation principle of this embodiment is:

[0049] The stainless steel pipe production and processing device is provided with an external grinding mechanism 6. When the outer surface of the stainless steel pipe needs to be ground, the staff puts one end of the stainless steel pipe on the outer surface of the pressing block 36. Then, the staff starts the motor 31. The rotation of the motor 31 can drive the threaded rod 32 to rotate. Since a connecting rod 34 is provided on the top of the threaded sleeve 33, the connecting rod 34 is rotatably connected with the rotating rod 35, thereby preventing the threaded sleeve 33 from rotating, and then the threaded sleeve 33 can be driven to move when the threaded rod 32 is turned. The movement of the threaded sleeve 33 can drive the connecting rod 34 to move, and since the internal opening of the connecting rod 34 There is a through hole 42, the rotating shaft 40 can rotate inside the through hole 42, the connecting rod 34 is rotatably connected to the mounting frame 30 through the connecting shaft 41, so that the rotating rod 35 can rotate, and because sliding blocks 39 are provided on both sides of the rotating shaft 40, the sliding blocks 39 can move inside the sliding groove 38, so that the threaded sleeve 33 can move, and the rotating rod 35 can drive the pressing block 36 to move, so that the pressing block 36 can contact the inner wall of the stainless steel pipe, so that the stainless steel pipe can be fixed, and stainless steel pipes of different sizes can be fixed, so that the application range of the equipment can be expanded. When the stainless steel pipe is fixed, the staff member screws the positioning pin 23, and the positioning pin 23 is disengaged from the positioning hole 24, so that the lifting rod 16 can be moved, and the grinding block 15 can be moved. Then, the staff member moves the lifting rod 16 to move the grinding block 15 toward each other, and screws the positioning pin 23 into another positioning hole 24. Then, the staff member rotates the turntable 12, and the rotation of the turntable 12 can drive the guide groove 18 to rotate, and the rotation of the guide groove 18 can drive the sliding rod 13 to move. Since a slider 20 is provided on one side of the sliding rod 13, and the slider 20 can move inside the slide groove 19 The movement of the sliding rod 13 can drive the fixed frame 14 to move, and the movement of the fixed frame 14 can drive the lifting rod 16 to move, which can drive the grinding block 15 to move, so that the grinding block 15 can contact the outer surface of the stainless steel pipe. At this time, since the clamping head contacts the inner wall of the stainless steel pipe, the motor 31 can drive the stainless steel pipe to rotate. Subsequently, the staff starts the first cylinder 2, and the first cylinder 2 can push the first telescopic rod 3 to extend and retract, so that the external grinding mechanism 6 can move, so that the outer surface of the stainless steel pipe can be polished.

[0050] When it is necessary to grind the inner surface of the stainless steel pipe, the staff member twists the fixing rod 44, and the fixing rod 44 is disengaged from the fixing hole 27, so that the moving rod 45 can be moved. When the position of the moving rod 45 is adjusted to the required position, the fixing rod 44 is screwed into the inside of the fixing hole 27, so that the moving rod 45 can be fixed, and then the grinding head 46 can be fixed. Then, the staff member puts the stainless steel pipe to the outside of the inner grinding mechanism 9 and rotates the turntable 12. The rotation of the turntable 12 can drive the sliding rod 13 to move, and then the fixing frame 14 can be driven to move. The movement of the fixing frame 14 can drive the clamping block 17 to move, so that the clamping block 17 can contact the outer surface of the stainless steel pipe, so that the outer surface of the stainless steel pipe can be fixed, so that stainless steel pipes of different sizes can be fixed, so that the application range of the equipment can be expanded. Then, the staff member The operator twists the fixing pin 26, and the fixing pin 26 contacts the fixing hole 27, so that the turntable 12 can be fixed, and then the stainless steel pipe can be fixed. Then, the operator starts the motor 31, and the rotation of the motor 31 can drive the threaded rod 32 to rotate, and the rotation of the threaded rod 32 can drive the connecting plate 43 to rotate, and the rotation of the connecting plate 43 can drive the fixing rod 44 to rotate, and the rotation of the fixing rod 44 can drive the moving rod 45 to rotate, and then the grinding head 46 can be driven to rotate. Since the grinding head 46 is located outside the pressing block 36, the motor 31 can be prevented from rotating the stainless steel pipe. Then, the operator starts the second cylinder 28, and the second cylinder 28 can drive the second telescopic rod 29 to retract, and then the grinding head 46 can be pushed to move, so that the inner surface of the stainless steel pipe can be polished, thereby expanding the scope of application of the equipment.

By rotating the motor 31, the threaded rod 32 can be driven to rotate, and then the rotating rod 35 can be driven to rotate, so that the inner surface of the stainless steel pipe can be fixed, so that stainless steel pipes of different sizes can be fixed, so that the application range of the equipment can be expanded;

[0053] 2. The stainless steel pipe production and processing device drives the rotating rod 35 to rotate by the motor 31, so that the pressing block 36 can contact the inner surface of the stainless steel pipe, thereby fixing the stainless steel pipe, and the outer surface of the stainless steel pipe can be polished by the polishing block 15. The clamping block 17 can be driven to move by rotating the turntable 12, so that the clamping block 17 can contact the outer surface of the stainless steel pipe, thereby fixing the stainless steel pipe, and the inner surface of the stainless steel pipe can be polished by the polishing head 46, thereby expanding the application range of the equipment.
