Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] like Figure 1-7 As shown, a communication solid wall pipe body circular cutting equipment includes an annular cutting frame 1 sleeved on the pipe body 3, a retaining frame 14 is slidably connected to the annular cutting frame 1, a guide rail groove 113 is provided on the annular cutting frame 1, a push block 16 is slidably connected in a recessed groove provided in the guide rail groove 113, a cutting blade 15 is movably provided on the retaining frame 14, the push block 16 is driven to push the cutting blade 15 to slide into the guide rail groove 113, so that the cutting blade 15 is driven to approach the pipe body 3 and rotate to cut, and the retaining frame 14 is driven to slide along the annular cutting frame 1 to perform circular cutting on the pipe body 3.

[0022] Specifically, the annular cutting frame 1 is arranged on a profile (which may be an aluminum alloy profile) so that the tube body 3 passes through the annular cutting frame 1. A retaining frame 14 is slidably connected to the annular cutting frame 1. The retaining frame 14 can move in a circle along the inner wall of the annular cutting frame 1 along the central axis of the annular cutting frame 1. The guide groove 113 faces the cutting blade 15. A movable groove 141 is provided on the retaining frame 14. The push block 16 is slidably connected to the movable groove 141. A blade groove 142 is provided on the movable groove 141. The blade groove 142 is used to guide the cutting blade 15. Move, when cutting is required, and then push the pushing block 16 through the driving source (telescopic motor or telescopic cylinder), so that the pushing block 16 slides along the recessed groove and the movable groove 141, and finally the pushing block 16 slides into the guide groove 113, so that the cutting blade 15 approaches the tube body 3 and starts to rotate for cutting. At this time, the retaining frame 14 will move along the guide groove 113 with the rotation of the cutting blade 15, so as to realize the annular cutting of the tube body 3. The pressure of the annular cutting is relatively small, and no pressure is generated during cutting. At the same time, the cut surface is flat, which is convenient for subsequent docking operations.

[0023] In the above technical solution, when it is necessary to cut the tube body 3, the pushing block 16 is first driven to push the cutting blade 15 toward the tube body 3 and rotate to cut the tube body 3. At this time, the retaining frame 14 is driven by the moving cutting blade 15 to move along the annular cutting frame 1 to perform an annular cutting on the tube body 3. During the annular cutting process, the tube body 3 will not be suppressed, is not easy to deform, and has a smooth cut surface, which is convenient for subsequent docking and grinding operations.

[0024] As an embodiment provided by the present invention, a coupling wheel 22 flexibly connected to the cutting blade 15 is movably provided on the retaining frame 14, a rotating ring 13 is rotatably connected to the annular cutting frame 1, and the coupling wheel 22 is driven to couple with the rotating ring 13; The annular cutting frame 1 comprises a fixed ring 11 and an extension frame 111 , a limiting frame 112 is arranged on the extension frame 111 , a rotating ring 13 is rotatably connected to the limiting frame 112 , and the rotating ring 13 is coupled to a power unit.

[0025] Specifically, the cutting blade 15 and the coupling wheel 22 are flexibly connected by a first spring 151. When the coupling wheel 22 rotates, the first spring 151 is driven to rotate and the cutting blade 15 is driven to rotate. The annular cutting frame 1 is rotatably connected to a rotating ring 13. The extension frame 111 is arranged on the fixed ring 11. The power unit can be a servo motor or a motor. When the cutting blade 15 moves due to the push of the push block 16, the coupling wheel 22 will also move accordingly, so that the coupling wheel 22 is coupled to the rotating ring 13, driving the cutting blade 15 to rotate.

[0026] When cutting is required, the driving source pushes the push block 16 so that the push block 16 slides along the recessed groove and the movable groove 141, and finally slides into the guide groove 113, which drives the coupling wheel 22 to couple the rotating ring 13, so that the cutting blade 15 starts to rotate, approaches the tube body 3 and starts to rotate for cutting. At this time, the retaining frame 14 moves along the guide groove 113 with the rotation of the cutting blade 15 to achieve annular cutting of the tube body 3.

[0027] As an embodiment provided by the present invention, a telescopic plate 17 is provided between the cutting blade 15, the coupling wheel 22 and the guide groove 113, and the telescopic plate 17 is assembled at the following two stations: First station: the telescopic plate 17 is driven to move and compress along the guide groove 113 to drive the cutting blade 15 and the coupling wheel 22 to rotate; Second station: the telescopic plate 17 extends to drive the cutting blade 15 to move.

[0028] Specifically, a spring plate 171 is provided on the telescopic plate 17. When the push block 16 is pushed and slides into the guide groove 113, the coupling wheel 22 and the rotating ring 13 are driven to couple, and as the cutting blade 15 continues to move, it will contact the tube body 3. At this time, the cutting blade 15 will press against the tube body 3 for rotational cutting, so that the spring plate 171 will be compressed along the telescopic plate 17 and switch to the first station. Then the cutting blade 15 rotates and moves with the retaining frame 14. When gradually cutting, it will switch to the second station. The telescopic plate 17 extends to drive the cutting blade 15 to move and continue to cut the tube body 3.

[0029] When cutting is required, the driving source pushes the pushing block 16 so that the pushing block 16 slides along the recessed groove and the movable groove 141, and finally slides into the guide groove 113, which drives the coupling wheel 22 to couple the rotating ring 13, so that the cutting blade 15 starts to rotate, approaches the tube body 3 and starts to rotate for cutting, so that the spring plate 171 is compressed along the telescopic plate 17. At this time, the retaining frame 14 moves along the guide groove 113 with the rotation of the cutting blade 15 to achieve annular cutting of the tube body 3. During cutting, the telescopic plate 17 extends to drive the cutting blade 15 to move and continuously cut the tube body 3.

A torsion spring is provided between the connecting base plate 23 and the telescopic plate 17. When the telescopic plate 17 moves with the push of the push block 16, the telescopic plate 17 pushes the connecting base plate 23 to move. At this time, the elastic member will first push the coupling wheel 22, and rotate with the connecting base plate 23 coupled to the rotating ring 13 to drive the cutting blade 15 to rotate, and then with the continued movement of the telescopic plate 17, the connecting base plate 23 will flip and drive the vertical plate so that the cutting blade 15 is close to the tube body 3 for cutting, which can ensure that the cutting blade 15 starts to rotate when it is not in contact with the tube body 3, so that the burrs on the cutting edge of the tube body 3 are reduced and the cutting surface is smoother. After the cutting is completed, the torsion spring cooperates with the push of the elastic member to flip and reset the connecting base plate 23 along the telescopic plate 17, so that the coupling wheel 22 finally disengages from the rotating ring 13.

[0032] When cutting is required, the driving source is used to push the pushing block 16 so that the pushing block 16 slides along the recessed groove and the movable groove 141, and finally slides into the guide groove 113. At this time, the elastic member will first push the coupling wheel 22, and then rotate with the base plate 23 coupled to the rotating ring 13 to drive the cutting blade 15 to rotate, so as to approach the tube body 3 and start to rotate for cutting, so that the spring plate 171 will be compressed along the telescopic plate 17. At this time, the retaining frame 14 will move along the guide groove 113 with the rotation of the cutting blade 15, and the telescopic plate 17 extends to drive the cutting blade 15 to move and continuously cut the tube body 3, thereby realizing annular cutting of the tube body 3.

[0034] Specifically, a bracket 144 is provided on the retaining frame 14, and the pressure rod 31 is rotatably connected to the bracket 144. A rotating ball is provided at the other end of the pressure rod 31. When the retaining frame 14 rotates along the annular cutting frame 1, the counterweight ball 32 is swung through centrifugal force to drive the pressure rod 31 to flip and make the rotating ball fit the outer wall of the tube body 3, thereby achieving a fixing effect. A second spring 311 is provided between the other end of the pressure rod 31 and the retaining frame 14, and the second spring 311 is used to pull the pressure rod 31 away from the tube body 3 for reset.

[0035] When cutting is required, the driving source is used to push the pushing block 16 so that the pushing block 16 slides along the recessed groove and the movable groove 141, and finally the pushing block 16 slides into the guide groove 113. At this time, the elastic member will first push the coupling wheel 22, and then rotate along with the base plate 23 coupled to the rotating ring 13 to drive the cutting blade 15 to rotate, so as to approach the tube body 3 and start to rotate for cutting, so that the spring plate 171 will be compressed along the telescopic plate 17. At this time, the retaining frame 14 will move along the guide groove 113 with the rotation of the cutting blade 15. At this time, the counterweight ball 32 will be swung by centrifugal force to drive the pressing rod 31 to flip and make the rotating ball fit the outer wall of the tube body 3. The telescopic plate 17 extends to drive the cutting blade 15 to move and continuously cut the tube body 3, thereby realizing annular cutting of the tube body 3.

[0036] As an embodiment provided by the present invention, it also includes a rotation mechanism 2, which includes a driving wheel 21 rotatably connected to the retaining frame 14, the driving wheel 21 is coupled to the inner wall of the annular cutting frame 1, and the driving wheel 21 is transmission-connected to the cutting blade 15; A guide plate 20 is provided on the retaining frame 14 , a synchronous roller 12 slidably connected to the guide plate 20 is provided on the cutting blade 15 , a tensioning wheel 202 is provided on the guide plate 20 , and a synchronous belt 211 is sleeved between the synchronous roller 12 , the tensioning wheel 202 and the driving wheel 21 .

[0037] Specifically, a rotating groove 143 is opened on the retaining frame 14, and the driving wheel 21 is rotatably connected to the rotating groove 143. A tensioning wheel 202 is arranged on the guide plate 20. A synchronous belt 211 is sleeved between the synchronous roller 12, the tensioning wheel 202 and the driving wheel 21. When the cutting blade 15 starts to rotate, it will drive the synchronous roller 12 to rotate, thereby driving the driving wheel 21 to rotate and couple the inner wall of the annular cutting frame 1, thereby driving the retaining frame 14 to rotate along the annular cutting frame 1, and the cutting blade 15 and the retaining frame 14 rotate in opposite directions.

[0038] When cutting is required, the driving source is used to push the pushing block 16 so that the pushing block 16 slides along the recessed groove and the movable groove 141, and finally the pushing block 16 slides into the guide groove 113. At this time, the elastic member will first push the coupling wheel 22, and then rotate along with the base plate 23 coupled to the rotating ring 13 to drive the cutting blade 15 to rotate, so as to approach the tube body 3 and start to rotate for cutting, so that the spring plate 171 will be compressed along the telescopic plate 17. At this time, the rotating cutting blade 15 will drive the synchronous roller 12 and the driving wheel 21 to rotate, so as to drive the driving wheel 21 to rotate and couple the inner wall of the annular cutting frame 1, and drive the retaining frame 14 to move along the guide groove 113 with the rotation of the cutting blade 15. At this time, the counterweight ball 32 will be swung by centrifugal force to drive the pressing rod 31 to flip and make the rotating ball fit the outer wall of the tube body 3. The telescopic plate 17 extends to drive the cutting blade 15 to move and continuously cut the tube body 3, thereby realizing annular cutting of the tube body 3.

[0039] As an embodiment provided by the present invention, a guide groove 201 is provided on the guide plate 20 , a frosting column 52 is slidably connected to the guide groove 201 , and the synchronous roller 12 is driven to slide along the guide groove 201 to drive the frosting column 52 to extend out of the guide groove 201 and fit the tube body 3 .

[0040] Specifically, a guide groove 201 is provided on the guide plate 20, and the guide groove 201 is inclined. When the cutting blade 15 continuously cuts the tube body 3 and continues to move, the synchronous roller 12 slides along the guide groove 201 and pushes the grinding column 52 obliquely against the guide groove 201 to contact the cut tube body 3, thereby removing burrs on the tube body 3 and reducing subsequent deburring steps.

[0041] When cutting is required, the driving source pushes the push block 16 to make the push block 16 slide along the recessed groove and the movable groove 141, and finally make the push block 16 slide into the guide groove 113. At this time, the elastic member will first push the coupling wheel 22, and then the base plate 23 will be coupled with the rotating ring 13 to rotate, so as to drive the cutting blade 15 to rotate, so as to approach the tube body 3 and start to rotate for cutting, so that the spring plate 171 will be compressed along the telescopic plate 17. At this time, the rotating cutting blade 15 will drive the synchronous roller 12 and the driving wheel 21 to rotate, so as to drive the driving wheel 21 The inner wall of the rotating coupled annular cutting frame 1 drives the retaining frame 14 to move along the guide groove 113 as the cutting blade 15 rotates. At this time, the counterweight ball 32 is swung by centrifugal force to drive the pressing rod 31 to flip and make the rotating ball fit the outer wall of the tube body 3. The telescopic plate 17 extends to drive the cutting blade 15 to move and continuously cut the tube body 3, thereby realizing annular cutting of the tube body 3. As the cutting blade 15 continuously cuts the tube body 3 and continues to move, the synchronous roller 12 tilts the grinding column 52 to contact the guide groove 201 to contact the cut tube body 3 to perform a deburring step.

[0042] As the best embodiment provided by the present invention, a vibration protrusion 121 is provided on the synchronous roller 12, and a flexible sliding column 51 slidably connected to the guide groove 201 is provided on the frosting column 52.

When the synchronous roller 12 rotates, the vibration protrusion 121 will push the flexible slide column 51 so that the flexible slide column 51 extends an additional distance from the guide groove 201. Then, when the vibration protrusion 121 passes over the flexible slide column 51, the elastic member will pull back the flexible slide column 51 to realize the reciprocating sliding of the flexible slide column 51, thereby increasing the reciprocating motion step of the frosting column 52 when the retaining frame 14 rotates, thereby enhancing the deburring effect.

[0044] When cutting is required, the driving source pushes the push block 16 to make the push block 16 slide along the recessed groove and the movable groove 141, and finally make the push block 16 slide into the guide groove 113.

At this time, the rotating cutting blade 15 will drive the synchronous roller 12 and the driving wheel 21 to rotate, so as to drive the driving wheel 21 to rotate and couple the inner wall of the annular cutting frame 1, and drive the retaining frame 1 4 will move along the guide groove 113 with the rotation of the cutting blade 15, and at this time, the counterweight ball 32 will be thrown by the centrifugal force to drive the pressing rod 31 to flip and make the rotating ball fit the outer wall of the tube body 3, and the telescopic plate 17 will extend to drive the cutting blade 15 to move and continuously cut the tube body 3, so as to achieve annular cutting of the tube body 3. As the cutting blade 15 continuously cuts the tube body 3 and continues to move, the grinding column 52 is tilted and pushed against the guide groove 201 to contact the cut tube body 3 for deburring. At the same time, the vibration protrusion 121 intermittently pushes the grinding column 52 to reciprocate with the rotation of the synchronous roller 12, so as to enhance the deburring effect.
