[0041] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0042] like Figures 1 to 5 As shown, a pipe cut end cleaning device comprises a frame 1, a trustee mechanism 2, a clamping mechanism 3, a cutting mechanism 4, a blowing mechanism 5 and a moving driving mechanism 6;

[0043] The trustee mechanism 2 is connected to the frame 1 and is used to hold the pipe 7 to be cut;

[0044] The clamping mechanism 3 is connected to the frame 1 and is used to clamp and fix the pipe 7 on the trustee mechanism 2;

[0045] The cutting mechanism 4 is used to cut the head of the tube 7 after the tube 7 is clamped;

[0046] The purge mechanism 5 is slidably connected to the frame 1 along the axial direction of the tube 7. During the sliding process, the purge mechanism 5 has an initial position separated from the tube 7 and a purge position covering the outside of the cutout on the tube 7 and purges the chips on the tube 7.

[0047] The mobile driving mechanism 6 is connected to the purging mechanism 5 and is used to drive the purging mechanism 5 to move between the purging position and the initial position. Specifically, firstly, the pipe 7 is placed on the trustee mechanism 2, and the pipe 7 on the trustee mechanism 2 is clamped and fixed by the clamping mechanism 3, and then the cutting mechanism 4 cuts off the head of the pipe 7. After the cutting is completed, the cutting mechanism 4 returns to its original position. At this time, there are many chips scattered on the inner and outer walls around the cut of the pipe 7. Then the mobile driving mechanism 6 drives the purging mechanism 5 to move to the purging position, and the purging mechanism 5 covers the outer side of the cut on the pipe 7 and purges the chips in the pipe 7, thereby blowing away the chips on the inner and outer walls, and then the mobile driving mechanism 6 drives the purging mechanism 5 to move to the initial position, and the clamping mechanism 3 releases the pipe 7 so that the pipe 7 can be taken away. The pipe head cleaning device of the embodiment of the present application can not only cut off the head of the pipe 7, but also blow away the chips on the inner and outer walls of the pipe 7, thereby improving the efficiency of cleaning the chips, eliminating the need for manual cleaning of the chips, and making it more convenient to use.

[0048] like Figures 1 to 4 As shown, the purge mechanism 5 may include an outer cover 8, at least one inner air pipe 9 and at least one outer air pipe 10;

[0049] The outer cover 8 is slidably connected to the frame 1 along the axial direction of the tube 7, and the moving drive mechanism 6 is connected to the outer cover 8 and is used to drive the outer cover 8 to move between the purge position and the initial position;

[0050] The inner air pipe 9 and the outer air pipe 10 are respectively connected to the outer cover 8 and are located on the inner side of the outer cover 8. When the outer cover 8 moves to the purge position, the outer cover 8 covers the outer side of the pipe 7 and the inner air pipe 9 extends to the inner side of the pipe 7 while the outer air pipe 10 extends to the outer side of the pipe 7. When the outer cover 8 moves to the initial position, the outer cover 8, the inner air pipe 9 and the outer air pipe 10 are respectively separated from the pipe 7.

[0051] The inner air pipe 9 and the outer air pipe 10 are connected to an external air source respectively; specifically, when purging is required, the mobile drive mechanism 6 drives the outer cover 8 to move toward the pipe 7 to the purging position, at which time the inner air pipe 9 extends into the inner side of the pipe 7, the outer air pipe 10 extends to the outer side of the pipe 7, and the outer cover 8 covers the outer side of the pipe 7. The inner air pipe 9 is connected to an external air source and purges the chips on the inner wall of the pipe 7, and the outer air pipe 10 is connected to an external air source and purges the chips on the outer wall of the pipe 7, thereby clearing the chips on the inner and outer walls of the pipe 7. After the purging is completed, the mobile drive mechanism 6 drives the outer cover 8 to move back to the initial position, so that the outer cover 8, the inner air pipe 9 and the outer air pipe 10 are separated from the pipe 7.

[0052] More specifically, the mobile driving mechanism 6 includes a mobile hydraulic cylinder, which is connected to the frame 1 and to the outer cover 8. The mobile hydraulic cylinder is used to drive the outer cover 8 to move between the purge position and the initial position. The outer cover 8 is provided to prevent chips from splashing. In this embodiment, the inner air pipe 9 and the outer air pipe 10 are respectively evenly distributed in the circumferential direction with 3.

[0053] like Figures 1 to 4 As shown, a chip discharge port 11 is provided at the lower end of the outer cover 8, a collecting port 12 is provided on the frame 1 below the cutting mechanism 4, and a chip collecting box 13 is provided below the collecting port 12. When the outer cover 8 moves to the purging position, the chip discharge port 11 is aligned with the collecting port 12; specifically, when the pipe 7 is cut, the pipe head waste and a part of the chips will directly pass through the collecting port 12 and fall into the chip collecting box 13, and the other part of the chips will be scattered on the inner and outer walls of the pipe 7. After the inner air pipe 9 and the outer air pipe 10 purge the chips on the inner and outer walls, the chips fall into the outer cover 8 and then are discharged from the chip discharge port 11 and pass through the collecting port 12 and fall into the chip collecting box 13.

[0054] like Figures 1 to 3 As shown, the cutting mechanism 4 may include a cutting execution component and a cutting drive component, wherein the cutting execution component is connected to the cutting drive component, and the cutting drive component is connected to the frame 1, and the cutting drive component is used to drive the cutting execution component to move toward the pipe 7 so that the cutting execution component cuts the head of the pipe 7.

[0055] like Figures 1 to 3 As shown, the frame 1 may include a cutting cantilever 14, the cutting execution assembly may include a cutting motor 15 and a cutting saw blade 16, and the cutting drive assembly may include a cutting hydraulic cylinder 17;

[0056] The cutting saw blade 16 is connected to the cutting motor 15;

[0057] The cutting motor 15 is connected to the cutting hydraulic cylinder 17;

[0058] The cutting hydraulic cylinder 17 is connected to the cutting cantilever 14, and is used to drive the cutting motor 15 to move toward and away from the pipe 7; in this embodiment, a cutting displacement sensor is also connected to the cutting motor 15, and the cutting displacement sensor is used to detect the cutting distance between the cutting motor 15 and the top of the cutting cantilever 14. Specifically, during the cutting process, the cutting hydraulic cylinder 17 drives the cutting motor 15 to move downward, and the cutting motor 15 drives the cutting saw blade 16 to rotate and cut the pipe 7. When the cutting distance measured by the cutting displacement sensor reaches the set value, it means that the cutting is completed. At this time, the cutting hydraulic cylinder 17 retracts and drives the cutting motor 15 to move upward.

[0059] like Figure 1 , 2 As shown in , 3 and 5, the clamping mechanism 3 may include an upper clamping assembly 18 located above the pipe 7 and a lower clamping assembly 19 located below the pipe 7, and the upper clamping assembly 18 and the lower clamping assembly 19 may include a clamping hydraulic cylinder 20, a pressure sensor 21 and a pressing component 22 respectively;

[0060] The pressing component 22 is connected to the pressure sensing device 21;

[0061] The pressure sensing device 21 is connected to the clamping hydraulic cylinder 20;

[0062] The clamping hydraulic cylinder 20 is connected to the frame 1, and is used to drive the pressure sensing device 21 and the clamping component 22 to move toward the pipe 7 in the up and down directions so that the clamping component 22 presses against the pipe 7; specifically, the clamping hydraulic cylinder 20 in the upper clamping assembly 18 drives the clamping component 22 to press against the upper end of the pipe 7, and the clamping hydraulic cylinder 20 in the lower clamping assembly 19 drives the clamping component 22 to press against the lower end of the pipe 7, thereby clamping and fixing the pipe 7, and the pressure sensing device 21 can detect the magnitude of the clamping force.

[0063] like Figure 5 As shown, the pressure sensing device 21 may include a first connecting plate 23, a second connecting plate 24, at least two guide pillars 25 and a force sensor 26;

[0064] The first connecting plate 23 is connected to the corresponding clamping hydraulic cylinder 20, and the second connecting plate 24 is connected to the corresponding pressing component 22, and the first connecting plate 23 and the second connecting plate 24 are arranged up and down;

[0065] The guide column 25 is connected to any one of the first connecting plate 23 and the second connecting plate 24;

[0066] The other of the first connecting plate 23 and the second connecting plate 24 is slidably connected to the guide post 25 in the up-down direction;

[0067] The force sensor 26 is connected to any one of the first connecting plate 23 and the second connecting plate 24 and is located between the first connecting plate 23 and the second connecting plate 24 .

[0068] In this embodiment, the guide post 25 is connected to the first connecting plate 23, the second connecting plate 24 is slidably connected to the guide post 25 along the up-down direction, and the force sensor 26 is connected to the second connecting plate 24. Specifically, when the clamping hydraulic cylinder 20 drives the first connecting plate 23 to move away from the pipe 7, the first connecting plate 23 drives the second connecting plate 24 to move away from the pipe 7 through the guide post 25, and then drives the pressing component 22 to move away from the pipe 7, so that the pipe 7 can be released. When the clamping hydraulic cylinder 20 drives the first connecting plate 23 to move toward the pipe 7, the first connecting plate 23 drives the second connecting plate 24 to move toward the pipe 7 through the guide column 25, and then drives the clamping component 22 to move toward the pipe 7 until the clamping component 22 is against the pipe 7, and then the clamping hydraulic cylinder 20 continues to drive the first connecting plate 23 to move toward the pipe 7, and the second connecting plate 24 slides relative to the guide column 25 to make the first connecting plate 23 and the second connecting plate 24 approach each other and finally press the force sensor 26. The force sensor 26 can detect the pressure between the first connecting plate 23 and the second connecting plate 24, and then can measure the clamping force of clamping the pipe 7.

[0069] like Figure 5 As shown, the pressing component 22 includes a seat 27 and at least one pair of pressing rollers 28;

[0070] The seat body 27 is connected to the second connecting plate 24;

[0071] The pressure roller 28 is connected to the seat body 27 and is used to abut against the pipe 7 . In the present embodiment, the supporting mechanism 2 includes at least two supporting blocks connected to the frame 1 and used to support the pipe 7 .

[0072] like Figure 1, 2 As shown in , 3 and 5, the frame 1 may include a clamping cantilever 29, and the clamping hydraulic cylinder 20 in the upper clamping assembly 18 is connected to the clamping cantilever 29;

[0073] The clamping component 22 in the upper clamping assembly 18 is connected with a clamping displacement sensor 30, and the clamping displacement sensor 30 is used to detect the reference distance between the clamping component 22 in the upper clamping assembly 18 and the clamping cantilever 29, and the clamping hydraulic cylinder 20 is used to drive the clamping component 22 to press against the pipe 7 according to the measured reference distance. Specifically, first, the clamping hydraulic cylinder 20 in the lower clamping assembly 19 drives the corresponding clamping component 22 to move upward to press against the lower end of the pipe 7, and when the pressure sensing device 21 in the lower clamping assembly 19 detects pressure, the clamping hydraulic cylinder 20 in the lower clamping assembly 19 stops moving. Then the clamping hydraulic cylinder 20 in the upper clamping assembly 18 drives the corresponding clamping component 22 to move downward to against the upper end of the pipe 7. When the pressure sensing device 21 in the upper clamping assembly 18 detects pressure, the clamping hydraulic cylinder 20 in the upper clamping assembly 18 stops moving. At this time, the output forces of the clamping hydraulic cylinders 20 in the upper clamping assembly 18 and the lower clamping assembly 19 are very small. At this time, the clamping displacement sensor 30 sends the measured reference distance to the external controller, and then under the control of the external controller, the clamping hydraulic cylinder 20 outputs a clamping force of appropriate size to clamp the pipe 7. Specifically, when the measured reference distance is larger, it means that the diameter of the pipe 7 is smaller, and the clamping force output by the clamping hydraulic cylinder 20 is controlled to be smaller; conversely, when the measured reference distance is smaller, it means that the diameter of the pipe 7 is larger, and the clamping force output by the clamping hydraulic cylinder 20 is controlled to be larger. Different clamping forces can be applied to pipes 7 of different diameters, so that the pipe 7 can be effectively clamped without being damaged.

[0074] In summary, firstly, the pipe 7 is placed on the trustee mechanism 2, and the pipe 7 on the trustee mechanism 2 is clamped and fixed by the clamping mechanism 3, and then the cutting mechanism 4 cuts off the head of the pipe 7. After the cutting is completed, the cutting mechanism 4 returns to its original position, and at this time, there are many chips scattered on the inner and outer walls around the cut of the pipe 7. Then the mobile drive mechanism 6 drives the purge mechanism 5 to move to the purge position, and the purge mechanism 5 covers the outer side of the cut on the pipe 7 and purges the chips in the pipe 7, thereby blowing away the chips on the inner and outer walls, and then the mobile drive mechanism 6 drives the purge mechanism 5 to move to the initial position, and the clamping mechanism 3 releases the pipe 7 so that the pipe 7 can be taken away. The pipe head cleaning device of the embodiment of the present application can not only cut off the head of the pipe 7, but also blow away the chips on the inner and outer walls of the pipe 7, thereby improving the efficiency of cleaning the chips, and does not need to manually clean the chips, which is more convenient to use.
