Description

Technical Field

[0001] This utility model relates to the technical field of burr removal devices, specifically a burr removal device for pipe cutting machine. Background Technology

[0002] The pipe cutting burr removal device of the pipe cutting machine is a device or component specifically used to remove burrs from the cut edge of the pipe after cutting. Its main function is to quickly and efficiently remove excess metal residue from the cut edge after the pipe is cut by mechanical, chemical or physical methods, thereby improving the processing quality of the pipe, ensuring that the cut surface is smooth and flat, and avoiding subsequent processing problems or safety hazards caused by burrs.

[0003] During machining, the cutting tool applies significant pressure when it comes into contact with the tube, causing plastic deformation of the material. Especially when the tool is withdrawn, the local compression and tearing of the material can cause burrs to form on the inner wall of the tube. These burrs usually appear as discontinuous tear marks, and their height can reach several hundred micrometers.

[0004] While existing external wall grinding technology has certain advantages in efficiency and uniformity, it often neglects the treatment requirements of the inner wall of the pipe. If the inner wall of the pipe is not treated after the outer wall of the pipe is ground, this uneven treatment of the inner and outer walls will not only affect the overall processing quality of the pipe, but may also lead to safety hazards in subsequent use. Therefore, in order to address the above problems, a pipe cutting machine burr removal device is proposed. Utility Model Content

[0030] Please see Figure 1-6 This utility model provides a technical solution:

[0031] A burr removal device for pipe cutting machines includes a machine base 1. A drive mechanism 4 is fixedly connected to the top of the machine base 1. An inner wall grinding assembly 5 is installed on the left side of the drive mechanism 4. An outer wall grinding assembly 6 is slidably connected to the inner side of the inner wall grinding assembly 5. The inner wall grinding assembly 5 includes a limiting shell 51. A guide rail groove 52 is formed on the inner side of the limiting shell 51. A first built-in slider 53 is slidably connected to the inner side of the guide rail groove 52. An extension rod 54 is rotatably connected to the inner side of the first built-in slider 53. A first bevel gear 55 and a first... The grinding rod 56 and the outer grinding assembly 6 include a second built-in slider 61. A second drive motor 62 is fixedly connected to the right side of the second built-in slider 61. An active rotating roller 63 is fixedly connected to the end of the main shaft of the second drive motor 62. Guide grooves 67 are opened at the upper and lower ends of the active rotating roller 63. A second bevel gear 65 is slidably connected to the inner side of the guide groove 67. A spring 64 is fixedly connected to the right side of the second bevel gear 65. A second grinding rod 66 is fixedly connected to the outer side of the active rotating roller 63. The second built-in slider 61 is slidably connected to the inner side of the guide rail groove 52.

[0032] As a further implementation of this solution, the drive mechanism 4 includes a vertical plate 41. The right side of the vertical plate 41 is fixedly connected to the housing of the first drive motor 42. A connecting rotating plate 43 is fixedly connected to the end of the main shaft of the first drive motor 42. The left side of the connecting rotating plate 43 is fixedly connected to the right side of the limiting shell 51. A shaft hole is opened on the inner side of the vertical plate 41. The main shaft of the first drive motor 42 extends out of the outer side of the shaft hole of the vertical plate 41. The axis of the main shaft of the first drive motor 42 is on the same horizontal line as the axis of the pipe body 7. The middle end of the connecting rotating plate 43 is fixed to the axis of the main shaft of the first drive motor 42. With the above settings, the inner wall grinding component 5 and the outer wall grinding component 6 can be controlled to rotate around the axis of the fixed frame 3, thereby achieving uniform and rapid grinding of the inner wall and outer side of the pipe body 7.

[0033] As a further implementation of this solution, a fixed frame 3 and a pipe cutting machine mechanism 2 are fixedly connected to the top of the machine base 1, and the bottom of the upright plate 41 is fixedly connected to the machine base 1 by bolts. A controller is fixedly connected to the front of the machine base 1. The controller, the first drive motor 42 and the second drive motor 62 of the machine base 1 are electrically connected. With the above settings, the pipe body 7 can be fixed to prevent the pipe body 7 from moving or rotating when grinding the pipe body 7, thereby improving the grinding quality.

[0034] As a further implementation of this solution, a threaded rod 57 is rotatably connected to the inner side of the limiting shell 51, and a threaded hole is opened on the inner side of the first built-in slider 53. A gap is set between the threaded hole of the first built-in slider 53 and the extension rod 54. The outer side of the threaded rod 57 is spirally connected to the inner side of the threaded hole of the first built-in slider 53. Through the above settings, the position of the grinding component can be flexibly adjusted, and it can be accurately adapted according to the diameter and wall thickness of the pipe, thereby enhancing the versatility and adaptability of the device.

[0035] As a further implementation of this solution, the outer side of the second grinding rod 66 is attached to the outer side of the tube body 7, the outer side of the first grinding rod 56 is attached to the inner side of the tube body 7, and the outer side of the first bevel gear 55 meshes with the outer side of the second bevel gear 65. Through the above arrangement, this attachment and meshing design ensures close contact between the grinding components and the tube, realizes simultaneous grinding of burrs on the inner and outer walls, improves grinding efficiency and quality, and reduces subsequent processing problems and safety hazards caused by burrs.

[0036] As a further implementation of this solution, the active rotating roller 63 is rotatably connected to the inner side of the second built-in slider 61 via a bearing. The slider is fixedly connected to the inner side of the second bevel gear 65, and the second bevel gear 65 is sleeved on the outer side of the active rotating roller 63. A limiting circular plate is fixedly connected to the outer side of the active rotating roller 63. The right end of the spring 64 is fixedly connected to the left side of the limiting circular plate of the active rotating roller 63. With the above configuration, the second grinding rod 66 can be driven to rotate by the second drive motor 62 to grind the outer side of the pipe body 7. The meshing of the second bevel gear 65 with the first bevel gear 55 drives the first grinding rod 56 to rotate, thereby grinding the inner wall of the pipe body 7. The cooperation of the inner wall grinding component 5 and the outer wall grinding component 6 can grind pipe bodies 7 with various inner wall sizes, improving the practicality of the device.

[0037] Workflow: When simultaneously grinding the outer and inner walls of the pipe body 7, the pipe body 7 is placed on the upper end of the fixing frame 3, with the grinding position of the pipe body 7 between the second grinding rod 66 and the first grinding rod 56. The pipe body 7 is then fixed by the fixing frame 3. According to the diameter and wall thickness of the fixing frame 3, the inner wall grinding assembly 5 and the outer wall grinding assembly 6 are adjusted. Rotating the threaded rod 57 drives the first built-in slider 53 to move. The first built-in slider 53 slides on the inner side of the guide rail groove 52. The first built-in slider 53 drives the extension rod 54, the first bevel gear 55, and the first grinding rod 56 to move simultaneously. When the outer side of the first grinding rod 56 is in contact with the inner wall of the tube body 7, it pushes the second bevel gear 65 to move to the right, causing the second bevel gear 65 to move away from the first bevel gear 55. The second bevel gear 65 compresses the spring 64, rotating the threaded rod 57 screwed on the outer grinding assembly 6, causing the second grinding rod 66 to move closer to the outer wall of the tube body 7. When the second grinding rod 66 is in contact with the outer side of the tube body 7, the second bevel gear 65 is released. Under the action of the spring force of the spring 64, the second bevel gear 65 meshes with the first bevel gear 55. The size of the first bevel gear 55 is the size of the second bevel gear 65. The first bevel gear 55 and the second bevel gear 65 have the same cross-sectional area on both sides. By configuring the first bevel gear 55 and the second bevel gear 65, the rotation of the second grinding rod 66, through mechanical linkage, can also drive the first grinding rod 56 to rotate, depending on the wall thickness of the pipe. When grinding burrs on the pipe body 7, the second drive motor 62 is activated, driving the drive roller 63, the second bevel gear 65, the spring 64, and the second grinding rod 66 to rotate simultaneously. The rotation of the second bevel gear 65 drives the first bevel gear 55 to rotate, and the first bevel gear 55 drives the first grinding rod 56 through the extension rod 54. The rotation achieves the effect of simultaneously polishing the burrs on the inside and outside of the pipe body 7. When the first drive motor 42 is started, it drives the first drive motor 42 and the limiting shell 51 to rotate, thereby causing the first polishing rod 56 and the second polishing rod 66 to rotate, achieving the effect of uniformly polishing the burrs on the pipe body 7. Through the above setting principle, the device can adjust the second polishing rod 66 and the first polishing rod 56 according to the diameter and wall thickness of the pipe body 7, thereby achieving the effect of simultaneously and uniformly polishing the inner and outer walls of the pipe body 7. This polishing method can improve the polishing quality of the pipe body 7 and ensure safety in later use.
