Description

Technical Field

[0001] The present invention relates to the technical field of clean pipelines for nuclear power, semiconductors, military industry, and aerospace, and specifically to an automatic pipe cutting and chamfering device for clean pipelines used in nuclear power, semiconductors, military industry, and aerospace. Background Art

[0002] The clean pipelines used in fields such as nuclear power, semiconductors, military industry, and aerospace are a pipeline system with extremely strict requirements for cleanliness, material, processing technology, and installation. Due to strict size requirements and limitations in pipeline installation space, etc., for the bent pipelines, it is necessary to cut off their excess length, so an automatic pipe cutting and chamfering device is required. The automatic pipe cutting and chamfering device cuts off the excess allowance through laser distance measurement and chamfers the pipe cutting part to eliminate burrs.

[0003] Due to the limitation of the installation space, the existing clean pipelines often produce bent pipelines with different bending degrees. When cutting pipes with different bending degrees, it is difficult to have a unified clamping method due to different bending degrees of each pipeline, and it is necessary to frequently adjust the position and angle of the clamping parts.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic pipe cutting and chamfering device for clean pipelines used in nuclear power, semiconductors, military industry, and aerospace is proposed.

[0007] Further, one end of the flexible pipe away from the insertion pipe is connected with a first inner support box, and the first inner support box is communicated with the insertion pipe through the flexible pipe.

[0008] Further, the insertion pipe is communicated with the second inner support box, and the corrugated pipe is communicated with the second inner support box and the first inner support box.

[0009] Further, a second electric trolley is arranged on one side of the guide rail, and a lifting push rod is arranged on the top of the second electric trolley. A first push rod is arranged on the top of the lifting push rod.

[0010] Further, a saw is connected to the end of the first push rod, and the saw is located above the pipe body.

[0011] Further, a chamfering assembly is arranged on the side of the second electric trolley. The chamfering assembly includes a second push rod, and the central axis of the second push rod is on the same horizontal straight line as the central axis of the pipe body.

[0014] Further, the chamfering assembly further includes a second motor, and the second motor is arranged at the end of the third push rod.

[0015] Further, the flat mouth component further includes a grinding disc and a roller. The end of the second motor is connected with the grinding disc, and the middle part of the surface of the grinding disc is rotatably connected with the roller.

[0016] The present invention provides an automatic pipe cutting and flat mouth device for clean pipes used in nuclear power, semiconductors, military industry, and aerospace, which has the following beneficial effects:

[0017] 1. When clamping the pipe body, the automatic pipe cutting and flat mouth device for clean pipes used in nuclear power, semiconductors, military industry, and aerospace does not clamp it from the outside, but inserts the first inner support box, the second inner support box, the adjusting rotating rod, and the inserting pipe into the pipe body.

Thus, the pipe body with different radian inner diameters can be clamped to improve the stability during the pipe cutting operation of the pipe body, and at the same time, it is not necessary to frequently adjust the position and angle of the clamping parts to adapt to the pipe body with different bending degrees.

[0018] 2. The automatic pipe cutting and flat mouth device for clean pipes used in nuclear power, semiconductors, military industry, and aerospace makes the first inner support box located at the pipe cutting part of the pipe body through the telescopic movement of the telescopic push rod, thereby providing an outward support from the inside at the cutting part to avoid the inner collapse of the pipe cutting part of the pipe body when cutting the pipe.

Thus, the burrs on the cut surface are removed when the grinding disc rotates circumferentially. Description of the Drawings

[0027] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0028] Such as Figures 1 - 6As shown in the figure, the present invention provides a technical solution: an automatic pipe cutting and chamfering device for clean pipes used in nuclear power, semiconductors, military industry, and aerospace, including a pipe clamping assembly 1 and a pipe body 2. The pipe clamping assembly 1 includes a guide rail 101, a first electric trolley 102, an adjustment motor 103, a carrier plate 104, a pump body 105, an extension pipe 106, an adjustment 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 corrugated pipe 113, and a flexible inner support piece 114. A first electric trolley 102 is slidably connected to the surface of the guide rail 101, and an adjustment motor 103 is fixed to the surface of the first electric trolley 102. The top of the adjustment motor 103 is connected to a carrier plate 104, and a pump body 105 is connected to the side of the carrier plate 104. The end of the pump body 105 is connected to an extension pipe 106, and an adjustment rotating rod 107 is rotatably connected to the end of the extension pipe 106. The end of the adjustment 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. A second inner support box 110 is connected to the outer wall of the extension pipe 106, and a flexible pipe 111 is connected to the end of the extension pipe 106. Transmission telescopic rods 112 are passed through the outer walls of the first inner support box 109 and the second inner support box 110, and flexible inner support pieces 114 are connected to the ends of the transmission telescopic rods 112. Corrugated pipes 113 are connected to both sides of the inner side surface of the flexible inner support pieces 114. The pipe body 2 is sleeved on the outer walls of the first inner support box 109 and the second inner support box 110. One end of the flexible pipe 111 away from the extension pipe 106 is connected to the first inner support box 109, and the first inner support box 109 is communicated with the extension pipe 106 through the flexible pipe 111. The extension pipe 106 is communicated with the second inner support box 110, and the corrugated pipes 113 are communicated with the second inner support box 110 and the first inner support box 109;

[0029] The specific operation is as follows. The pipe body 2 with a curvature is sleeved on the outer walls of the first inner support box 109 and the second inner support box 110. During the sleeving process, the first inner support box 109 and the second inner support box 110 change from a linear distribution to form an included angle with the curvature of the pipe body 2 through the adjustment rotating rod 107 to 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 bent part of the pipe body 2, and the position of the first inner support box 109 is adjusted by the telescopic movement of the telescopic push rod 108 so that the first inner support box 109 is located at the pipe cutting part of the pipe body 2;

[0030] 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;

[0031] 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.

[0032] like Figures 1 - 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;

[0033] The specific operation is as follows. After the pipe body 2 with different bends and different inner diameters is stably clamped by being expanded outward by the flexible inner support piece 114, the motor 103 is adjusted to drive the carrier plate 104 to rotate, so that the end face of the pipe body 2 faces the side of the electric saw 6. After the cutting position of the pipe is determined by the laser rangefinder, the position of the electric saw 6 is adjusted by the sliding of the second electric pulley 3 and the telescoping 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 electric saw 6 is driven to descend by the lifting push rod 4 to perform pipe cutting operation on the pipe body 2;

[0034] After the pipe cutting operation, the electric saw 6 is lifted, and the second push rod 701 extends, and the third push rod 703 telescopes, so that the surface of the grinding disc 705 abuts against the cut surface of the pipe body 2, and the roller 706 abuts against the surface of the pipe body 2. The grinding disc 705 is driven to rotate against the cut surface by the first motor 702, and the roller 706 rolls circumferentially on the surface of the pipe body 2. At the same time, the grinding disc 705 is driven to rotate by itself by the second motor 704. Thus, the grinding disc 705 eliminates the burrs on the cut surface while making a circular motion, thereby realizing the flat-mouth treatment of the cut surface;

[0035] Based on the above description, in the present invention, through the telescoping of the second push rod 701 and the third push rod 703, the grinding disc 705 rotates circumferentially and rotates by itself against the cut surface under the driving action of the first motor 702 and the second motor 704, while the roller 706 rolls circumferentially on the surface of the pipe body 2. Thus, the burrs on the cut surface are eliminated when the grinding disc 705 makes a circular self-rotation motion.

[0036] In summary, for the automatic pipe cutting and flat-mouth equipment for the clean pipe used in nuclear power, semiconductors, military industry, and aerospace, during use, first, the pipe body 2 with a curvature is sleeved on the outer walls of the first inner support box 109 and the second inner support box 110. During the sleeving process, the first inner support box 109 and the second inner support box 110 change from a linear distribution to form an included angle and adapt to the curvature of the pipe body 2 by adjusting the rotating rod 107 according 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 bent part of the pipe body 2, and the position of the first inner support box 109 is adjusted by the telescoping of the telescoping push rod 108, so that the first inner support box 109 is located at the pipe cutting position of the pipe body 2;

[0037] Then, a transmission medium such as hydraulic oil is injected into the extension pipe 106 through the pump body 105. The hydraulic oil enters the interior of the second inner support box 110 and then enters the interior of the first inner support box 109 through the flexible pipe 111. Thereby, the transmission telescopic rods 112 inside the first inner support box 109 and the second inner support box 110 are pushed out, causing the flexible inner support pieces 114 to expand outward so that their middle parts first abut against the inner wall of the pipe body 2. And during the subsequent injection of hydraulic oil, it enters the interior of the corrugated pipe 113. Thereby, the corrugated pipe 113 extends to apply a thrust force to both ends of the flexible inner support piece 114. The two ends of the flexible inner support piece 114 are deformed by the force, causing its entire outer wall to adhere to the inner wall of the pipe body 2, thereby supporting it from the inner wall of the pipe body 2;

[0038] After the pipe body 2 with different bends and different inner diameters is stably clamped by the outward expansion of the flexible inner support piece 114, the motor 103 is adjusted to drive the carrier plate 104 to rotate, so that the end straight surface of the pipe body 2 faces the side surface of the electric saw 6. After the electric saw 6 determines the pipe cutting position through laser ranging, the position is adjusted by the sliding of the second electric trolley 3 and the telescoping 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 electric saw 6 is driven to descend by the lifting push rod 4 to perform pipe cutting operation on the pipe body 2;

[0039] After the pipe cutting operation, the electric saw 6 is lifted, and the second push rod 701 extends, and the third push rod 703 telescopes, so that the surface of the grinding disc 705 abuts against the cut surface of the pipe body 2, and the roller 706 adheres to the surface of the pipe body 2. The grinding disc 705 is driven to rotate against the cut surface by the first motor 702, and the roller 706 rolls circumferentially on the surface of the pipe body 2. At the same time, the grinding disc 705 is driven to rotate by itself by the second motor 704. Thereby, the grinding disc 705 eliminates the burrs on the cut surface while performing circular motion, thereby realizing the flat mouth treatment of the cut surface.
