[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

The clamping mechanism 1 in the above design is used to clamp the pipe 2 during cutting to prevent the pipe from moving during beveling processing and ensure the accuracy of processing.

[0026] See also Figure 2 , Figure 2 for Figure 1 A schematic diagram of a structure of an embodiment of a clamping mechanism. The clamping mechanism 1 also includes a frame 12 and a height adjustment assembly 13, and the height adjustment assembly 13 is located below the frame 12; the frame 12 is hollow and has a slide rail 14 at the upper and lower ends of the same side, a fixed block 15 and a sliding block 16 are provided between the slide rails 14, and a V-shaped clamp block 11 is provided on the opposite side of the sliding block 16 and the fixed block 15; a first cylinder 17 connected to the sliding block 16 is provided on one side of the slide rail 14; wherein the top end of the telescopic rod of the first cylinder 17 is connected to one of the sliding blocks 16, and the end of the extension cylinder body of the first cylinder 17 is connected to the other sliding block 16. The telescopic movement of the first cylinder 17 in the above design can control the opening and closing of the V-shaped clamp blocks 11 on both sides, thereby completing the clamping and loosening of the pipe 2. In other embodiments, the V-shaped clamp block 11 can be designed to be convenient for clamping, such as a rotating arc clamp block. Different cylinders are also provided on both sides of the slide rail 14 to control the opening and closing of the clamp block.

[0027] See also Figure 3 , Figure 3 for Figure 2The height adjustment assembly 13 comprises a base frame 131 and a second cylinder 132. Slide holes 133 are provided on both sides of the base frame 131. Two pillars 121 and a lifting column 122 are arranged in parallel at the bottom of the frame 12. The pillars 121 are slidably sleeved in the slide holes 133. A support plate 134 is arranged in the middle of the base frame 131. The second cylinder 132 is arranged below the support plate 134 to abut against the support plate 134. A frame plate 135 is arranged inside one side of the base frame 131. A first motor 136 is passed through the frame plate 135. A bevel gear 137 is sleeved on the rotating shaft of the first motor 136. The bevel gear 137 is meshed with a lifting rack 138 fixed to the side of the lifting column 122. The rotation of the first motor 136 in the above design can drive the bevel gear 137 to rotate, thereby driving the lifting column 122 with the lifting rack 138 to move up and down. When the preset height is reached, the second cylinder 132 can be used to support the entire frame 12, and then the clamping operation of the pipe is completed to prevent the clamping mechanism 1 from sinking during the pipe cutting operation. Alternatively, the second cylinder 132 can be used to control the rise and fall of the entire frame 12, while the drive motor rotates the gear and calculates the lifting distance. When the preset distance is reached, the drive motor stops, and the cylinder also stops moving, so that the frame 12 is maintained at the preset height.

[0028] See also Figure 4 , Figure 4 for Figure 1 A schematic diagram of the structure of an embodiment of a driving frame. The cutting mechanism includes a knife-edge cylinder 5 and a driving frame 4. A base 42 is provided at the bottom of the driving frame 4.

The driving frame 4 is sleeved with a rotating sleeve 41 for driving the knife-edge cylinder 5 to rotate. The rotating sleeve 41 is connected to the knife-edge cylinder 5 and is concentrically arranged. The extension and retraction of the third cylinder 43 in the above design can control the height of the driving frame 4 and the knife-edge cylinder 5, so that the pipe 2 can pass through the center of the knife-edge cylinder 5 and the driving frame 4, ensuring the accuracy of the groove processing.

[0029] See also Figure 5 , Figure 5 for Figure 4 The structure diagram of an embodiment of a rotating sleeve in the middle. A plurality of sleeve rods 45 are arranged in parallel on the outside of the rotating sleeve 41 in the driving frame 4. A plurality of sets of rolling wheels 46 are sleeved on the outside of the sleeve rods 45. The outside of the rolling wheels 46 is engaged with the annular track 47 located on the outside of the rotating sleeve 41, so that the rotating sleeve 41 rotates through the annular track 47. The rotating sleeve 41 in the above design is assumed to be between the rolling wheels 46. The rolling wheels 46 can rotate freely on the sleeve rods 45, so that the rotating sleeve 41 can also rotate freely through the outer annular track 47, thereby driving the knife-edge cylinder 5 to rotate.

[0030] An annular rack wheel 48 is provided on the outer wall of the rotating sleeve 41 which is close to the knife edge cylinder 5. The annular rack wheel 48 in the above design is convenient for driving the rotating sleeve 41 to rotate from the outside.

[0031] A motor port 49 is provided on one side of the drive frame 4 near the knife-edge cylinder 5, and a second motor 6 is provided in the motor port 49. The rotating shaft sleeve of the second motor 6 is provided with a driving gear 61 meshed with the annular rack wheel 48. The second motor 6 in the above design can drive the driving gear 61 to rotate, thereby driving the entire rotating sleeve 41 and the knife-edge cylinder 5 to rotate through the annular rack wheel 48 meshed therewith, so as to facilitate the groove processing.

[0032] See also Figure 6 , Figure 6 for Figure 1 A schematic diagram of the cross-sectional structure of an embodiment of a middle blade tube. The blade tube 5 is provided with four groups of evenly distributed strip openings 51 on the side away from the driving frame 4. The strip openings 51 are provided with a telescopic cutter assembly 3 that moves along the strip openings 51. The telescopic cutter assembly 3 includes a knife seat 31 extending out of the inner wall of the blade tube 5. The end of the knife seat 31 is fixedly connected with a cutter 32 for cutting the coffin pipe. The cutter 32 in the above design extends out of the inner wall of the blade tube 5. When the blade tube 5 rotates, the cutter 32 performs groove processing on the pipe along the outer diameter. At the same time, the telescopic cutter assembly 3 can control the telescopic distance of the blade, which is convenient for adjustment according to the size of the pipe and the cutting requirements, and is flexible and convenient.

[0033] See also Figure 7 , Figure 7 for Figure 1 A schematic cross-sectional structure diagram of an embodiment of a telescopic cutter assembly. The inner side of the blade barrel 5 is provided with an inner groove 52 corresponding to the cutter 32 frame and a third motor 53. The inner groove 52 is provided with corresponding shaft plates 54 on opposite sides of the inner and outer diameters. The shaft plate 54 is provided with a bearing 55. The inner diameter of the bearing 55 is sleeved with a screw 56. One end of the screw 56 is fixedly connected with a first bevel gear 57. The third motor 53 is arranged vertically with the screw 56. The rotating shaft of the third motor 53 is sleeved with a second bevel gear 58 meshing with the first bevel gear 57. The positions of the bearings 55 of the two side shaft plates 54 in the above design correspond to each other. The two ends of the screw 56 are sleeved in the bearings 55 of the two side shaft plates 54, so that the screw 56 can rotate freely. The third motor 53 drives the first bevel gear 57 to rotate through the second bevel gear 58, thereby driving the screw 56 to rotate.

[0034] The telescopic cutter assembly 3 includes a T-shaped track 33 and an outer plate 34 that penetrates the strip-shaped opening 51. The knife holder 31 is fixed to the end of the outer plate 34. A sliding plate 35 connected to the T-shaped track 33 is provided in the inner groove 52. A threaded plate 36 is vertically fixed to the back of the sliding plate 35. A threaded hole for sleeve-connecting the screw 56 is provided in the middle of the threaded plate 36. The threaded plate 36 in the above design is sleeved on the screw 56 through the threaded hole. The screw 56 is parallel to the strip-shaped opening 51. The rotation of the screw 56 can drive the threaded plate 36 to move back and forth, thereby adjusting the overall position of the telescopic cutter assembly 3. At the same time, the T-shaped track 33 can move along the strip-shaped opening 51 to adjust the specific positions of the knife holder 31 and the cutter 32. The sliding plate 35 can slide relatively on the T-shaped track 33 to further adjust the position of the knife holder 31. Then, the specific position of the sliding plate 35 can be fixed by setting a fixing bolt or the like to prevent the sliding plate 35 from moving.

[0035] The specific working method is to transport the required pipe 2 to the middle of the clamping mechanism 1 and the cutting mechanism through the external conveying assembly, and then adjust the height of the clamping mechanism 1 and the driving frame 4 according to the size and specification of the pipe, so that the pipe is located between the V-shaped clamping blocks 11, and the pipe is located at the center of the rotating sleeve 41 and the knife edge cylinder 5, so that the distance between the cutting knives 32 and the pipe is the same. Then open the first cylinder 17, so that the V-shaped clamping blocks 11 on both sides clamp the pipe to ensure that the pipe will not move during processing. Then, the third motor 53 adjusts the position of the cutter 32 according to the bevel requirement so that the cutter 32 can cut around the pipe. At the same time, the second motor 6 is turned on to drive the entire rotating sleeve 41 and the knife-edge cylinder 5 to rotate through the annular rack wheel 48. The cutter 32 cuts and bevels the pipe along the outer wall of the pipe according to the set program. After completion, the cutter 32 retracts and stops the second motor 6, thereby stopping the rotation of the rotating sleeve 41, and removing one end of the pipe 2 that has completed the bevel processing. Then, a new pipe is continuously fed in and the above steps are repeated.

[0036] The present application can not only complete various common forms of beveling processing covered by traditional beveling machines by precisely controlling radial and axial precise feeding, but also can process any shape of curved beveling processing required by the user. The present application can dynamically adjust the position and feed speed of the tool in the telescopic cutter assembly 3 to adapt to different processing requirements, greatly expanding the form and application scope of pipe beveling processing. At the same time, the telescopic cutter assembly 3 does not need to replace the tool. Through the modular device and the multifunctional tool holder, the common blade can be used to realize the rapid switching of beveling angles and sizes of different specifications, saving the tool replacement time.
