[0022] like Figure 1-Figure 6As shown, the present invention provides a technical solution: an automated pipe cutting and flattening device for clean pipes used in nuclear power, semiconductor, military and aerospace industries, comprising a pipe clamping assembly 1 and a pipe body 2, wherein the pipe clamping assembly 1 comprises a guide rail 101, a first electric pulley 102, an adjusting motor 103, a carrier plate 104, a pump body 105, an insertion pipe 106, an adjusting rotating rod 107, a telescopic push rod 108, a first inner support box 109, a second inner support box 110, a flexible pipe 111, a transmission telescopic rod 112, a bellows 113 and a flexible inner support sheet 114, the surface of the guide rail 101 is slidably connected to the first electric pulley 102, and the surface of the first electric pulley 102 is fixed with the adjusting motor 103, the top of the adjusting motor 103 is connected to the carrier plate 104, and the side of the carrier plate 104 is connected to the pump body 105, the end of the pump body 105 is connected to the insertion pipe 106, and the end of the insertion pipe 106 is rotatably connected to the adjusting rotating rod 107 The end of the adjusting rotating rod 107 is rotatably connected to a telescopic push rod 108, and the end of the telescopic push rod 108 is connected to a first inner support box 109, the outer wall of the insertion tube 106 is connected to a second inner support box 110, and the end of the insertion tube 106 is connected to a flexible tube 111, the outer walls of the first inner support box 109 and the second inner support box 110 are penetrated with a transmission telescopic rod 112, and the end of the transmission telescopic rod 112 is connected to a flexible inner support sheet 114, and the flexible inner support sheet 111 4 is connected to the inner side surfaces thereof with bellows 113, the first inner support box 109, the outer wall of the first inner support box 109 is sleeved with the pipe body 2, the end of the flexible tube 111 away from the insertion tube 106 is connected to the first inner support box 109, and the first inner support box 109 is connected to the insertion tube 106 through the flexible tube 111, the insertion tube 106 is connected to the second inner support box 110, and the bellows 113 is connected to the second inner support box 110 and the first inner support box 109; The specific operation is as follows: the pipe body 2 with an arc is sleeved on the outer walls of the first inner support box 109 and the second inner support box 110. During the sleeved process, the first inner support box 109 and the second inner support box 110 are adjusted from a straight line distribution by adjusting the rotating rod 107 to change with the arc of the pipe body 2 so that the first inner support box 109 and the second inner support box 110 generate an angle and adapt to the arc of the pipe body 2. At this time, the outer walls of the first inner support box 109 and the second inner support box 110 are respectively located on both sides of the curved part of the pipe body 2, and the first inner support box 109 is adjusted in position by the extension and retraction of the telescopic push rod 108, so that the first inner support box 109 is located at the part of the pipe body 2 to be cut; Then, a transmission medium such as oil is injected into the insertion tube 106 through the pump body 105, and the oil enters the second inner support box 110 and enters the first inner support box 109 through the flexible tube 111, thereby pushing the transmission telescopic rod 112 inside the first inner support box 109 and the second inner support box 110 to extend, so that the flexible inner support sheet 114 expands outward so that its middle part preferentially abuts against the inner wall of the pipeline body 2, and enters the bellows 113 during the subsequent oil injection process, thereby causing the bellows 113 to stretch and apply thrust to both ends of the flexible inner support sheet 114, and the two ends of the flexible inner support sheet 114 are deformed by force so that its entire outer wall is attached to the inner wall of the pipeline body 2, thereby supporting it from the inner wall of the pipeline body 2; Based on the above description, the present invention does not clamp the pipe body 2 from the outside, but extends the first inner support box 109, the second inner support box 110, the adjustment rod 107, and the insertion tube 106 into the pipe body 2. By adjusting the adjustment rod 107 as the curvature of the pipe body 2 changes, the first inner support box 109 and the second inner support box 110 are respectively located on both sides of the curved part of the pipe body 2, and oil is injected through the pump body 105 to make the flexible inner support sheet 114 expand outward and deform so that it is completely attached to the inner wall of the pipe body 2. In this way, the pipe body 2 with different curvatures and inner diameters can be clamped to improve the stability of the pipe body 2 during pipe cutting. At the same time, there is no need to frequently adjust the position and angle of the clamping member to adapt to the pipe body 2 with different curvatures. In addition, the first inner support box 109 is located at the pipe cutting part of the pipe body 2 through the extension and retraction of the telescopic push rod 108, thereby providing support from the inside to the outside at the cutting part to avoid the pipe cutting part of the pipe body 2 being stressed and collapsed inward during pipe cutting.

[0023] like Figure 1-Figure 6 As shown, a second electric pulley 3 is arranged on one side of the guide rail 101, and a lifting push rod 4 is arranged on the top of the second electric pulley 3, and a first push rod 5 is arranged on the top of the lifting push rod 4, and an electric saw 6 is connected to the end of the first push rod 5, and the electric saw 6 is located above the pipeline body 2, and a flat-mouth component 7 is arranged on the side of the second electric pulley 3, and the flat-mouth component 7 includes a second push rod 701, and the central axis of the second push rod 701 is on the same horizontal straight line as the central axis of the pipeline body 2, and the flat-mouth component 7 also includes A first motor 702, an end of the second push rod 701 is connected to the first motor 702, the flat-mouth assembly 7 further includes a third push rod 703, an end of the first motor 702 is connected to the third push rod 703, the flat-mouth assembly 7 further includes a second motor 704, an end of the third push rod 703 is provided with the second motor 704, the flat-mouth assembly 7 further includes a grinding disc 705 and a roller 706, an end of the second motor 704 is connected to the grinding disc 705, and the middle of the surface of the grinding disc 705 is rotatably connected to the roller 706; The specific operation is as follows: after the pipe body 2 with different bends and different inner diameters is expanded outwards and clamped stably by the flexible inner support sheet 114, the motor 103 is adjusted to drive the carrier plate 104 to rotate so that the end of the pipe body 2 directly faces the side of the electric saw 6. After the laser distance measurement determines the pipe cutting position, the electric saw 6 slides through the second electric pulley 3 and adjusts the position of the first push rod 5 so that the electric saw 6 is located above the pipe cutting position on the surface of the pipe body 2, and then the lifting push rod 4 drives the electric saw 6 to descend to cut the pipe body 2; After the pipe cutting operation, the electric saw 6 is lifted, the second push rod 701 is extended, and the third push rod 703 is retracted, so that the surface of the grinding disc 705 is against the cut surface of the pipe body 2, and the roller 706 is attached to the surface of the pipe body 2. The grinding disc 705 is driven by the first motor 702 to rotate on the cut surface, and the roller 706 is attached to the surface of the pipe body 2 and rolls in a circle. At the same time, the grinding disc 705 is driven by the second motor 704 to rotate, so that the grinding disc 705 removes the burrs on the cut surface while moving in a circle, thereby achieving a flat cut surface. Based on the above description, the present invention extends and retracts the second push rod 701 and the third push rod 703, so that the grinding disc 705 rotates in a circle close to the cut surface and rotates at the same time under the drive of the first motor 702 and the second motor 704, and the roller 706 rolls in a circle close to the surface of the pipe body 2, thereby eliminating burrs on the cut surface when the grinding disc 705 rotates in a circle.

[0024] In summary, when the automatic pipe cutting and flattening equipment for clean pipes used in nuclear power, semiconductor, military and aerospace industries is used, the pipe body 2 with a curvature is first sleeved on the outer walls of the first inner support box 109 and the second inner support box 110. During the sleeve insertion process, the first inner support box 109 and the second inner support box 110 are adjusted from a straight line distribution by the rotating rod 107 to change with the curvature of the pipe body 2 so that the first inner support box 109 and the second inner support box 110 generate an angle and adapt to the curvature of the pipe body 2. At this time, the outer walls of the first inner support box 109 and the second inner support box 110 are respectively located on both sides of the curved part of the pipe body 2, and the first inner support box 109 is adjusted in position by the extension and retraction of the telescopic push rod 108, so that the first inner support box 109 is located at the part of the pipe body 2 to be cut; Then, a transmission medium such as oil is injected into the insertion tube 106 through the pump body 105, and the oil enters the second inner support box 110 and enters the first inner support box 109 through the flexible tube 111, thereby pushing the transmission telescopic rod 112 inside the first inner support box 109 and the second inner support box 110 to extend, so that the flexible inner support sheet 114 expands outward so that its middle part preferentially abuts against the inner wall of the pipeline body 2, and enters the bellows 113 during the subsequent oil injection process, thereby causing the bellows 113 to stretch and apply thrust to both ends of the flexible inner support sheet 114, and the two ends of the flexible inner support sheet 114 are deformed by force so that its entire outer wall is attached to the inner wall of the pipeline body 2, thereby supporting it from the inner wall of the pipeline body 2; After the pipe bodies 2 with different bends and inner diameters are expanded outwards and clamped stably by the flexible inner support sheet 114, the motor 103 is adjusted to drive the carrier plate 104 to rotate so that the end of the pipe body 2 directly faces the side of the electric saw 6. After the laser distance measurement determines the pipe cutting position, the electric saw 6 slides through the second electric pulley 3 and adjusts the position of the first push rod 5 so that the electric saw 6 is located above the pipe cutting position on the surface of the pipe body 2. Then, the lifting push rod 4 drives the electric saw 6 to descend to cut the pipe body 2. After the pipe cutting operation, the electric saw 6 is lifted, the second push rod 701 is extended, and the third push rod 703 is retracted, so that the surface of the grinding disc 705 is against the cut surface of the pipe body 2, and the roller 706 is attached to the surface of the pipe body 2. The grinding disc 705 is driven by the first motor 702 to rotate close to the cut surface, and the roller 706 is attached to the surface of the pipe body 2 and rolls in a circle. At the same time, the grinding disc 705 is driven by the second motor 704 to rotate, so that the grinding disc 705 eliminates burrs on the cut surface while moving in a circle, thereby achieving a flat cut surface.
