Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipe processing, and in particular to a pipe end finishing device. Background Technology
[0002] During pipe cutting, burrs and bumps are easily formed on the sidewalls of the pipe opening. If these are not removed, they will affect the sealing of the pipe connection and disrupt the flow of materials inside the pipe. For granular or powdery materials, these bumps can become dead zones where materials can stagnate.
[0003] Patent application number CN202320072639.5 discloses an integrated device for pipe end trimming and deburring, which uses a trimming disc and a grinding disc to grind burrs on the pipe surface and the inside of the pipe opening. However, this grinding device has requirements for the inner and outer diameters of the pipe and can only be used for pipes of one size; moreover, the trimming disc and the grinding disc are difficult to replace, resulting in poor applicability and inconvenience in the use of the entire device. Utility Model Content
[0004] To address the problems of poor applicability and inconvenience in using existing pipe end finishing devices, this application provides a pipe end finishing device.
[0005] This application provides a pipe end finishing device, which adopts the following technical solution: The device includes a work platform with a processing table and a support frame. A clamping assembly is mounted on the processing table, and a pipe to be processed is vertically positioned on the processing table. The bottom of the pipe is detachably fixed by the clamping assembly. A rotating seat is rotatably mounted on the support frame, positioned above the pipe. A cutting blade is mounted at the bottom of the rotating seat, with its tip fitting against the sidewall of the pipe. A through-slot is radially formed at the bottom of the rotating seat, and the cutting blade is detachably fixed to the bottom of the rotating seat by a capped bolt passing through the through-slot. The support frame also includes a lifting assembly and a rotating assembly. The lifting assembly drives the rotating seat to rise and fall, and the rotating assembly drives the rotating seat to rotate.
[0006] By adopting the above technical solution, the cutting blade is fixed to the bottom of the rotating base by the tightening force of the cap bolt. When the rotating base drives the entire cutting blade to rotate and cut, the side wall of the cap bolt is in close contact with the inner side of the through groove. The cap bolt provides support force in the rotation direction for the cutting blade. The rotation of the cutting blade cuts the outer wall of the pipe opening, thus performing fine finishing on the pipe to be processed. The cutting blade can move along the through groove, thereby adjusting the distance between the cutting blade and the center position of the rotating base, so that the blade tip can always be in contact with the outer wall of the pipe to be processed. The entire device can cut pipes of various sizes, and the movement and disassembly of the cutting blade are more convenient.
[0007] Preferably, the lifting assembly includes a mounting plate and a lead screw module, the support frame is disposed on the side of the processing table, the mounting plate is slidably connected to the support frame, and the lead screw module drives the mounting plate to move vertically on the support frame; the rotating assembly includes a bearing rotatably disposed on the mounting plate and a rotating motor that drives the bearing to rotate, and the rotating seat is disposed at the bottom of the bearing and rotates with the bearing.
[0008] By adopting the above technical solution, the entire rotating seat can not only rotate but also move up and down, making it suitable for pipes of different heights. Furthermore, it can be raised and lowered during rotation. If the burrs and protrusions are large, conventional cutting tools may be obstructed by the protrusions inside the pipe, preventing adjustment to the appropriate cutting size. However, with the above solution, the cutting tool position is first adjusted above the pipe to be processed, and then the cutting tool is slowly lowered into the pipe. This method is suitable for fine finishing of pipe openings with large burrs and protrusions.
[0009] Preferably, it also includes an outer shell, which covers the processing table and the rotating seat. The top surface and three sides of the outer shell are closed, and a window is opened on the remaining side. A baffle is provided between the processing table and the window. The baffle is provided on the side of the processing table and can be moved vertically to cover or open the window.
[0010] By adopting the above technical solution, the outer shell can cover the finishing space of the pipe to be processed, preventing debris generated during the finishing process from splashing out. The baffle can cover the window during the finishing process to prevent debris from flying out of the window. When it is necessary to change the material to be processed or the cutting blade, the baffle can be moved down to open the window, making it convenient to change the cutting blade or the material to be processed.
[0011] Preferably, the baffle is provided with a vertical sliding rod, and the processing table has a sliding groove on the side near the baffle. The sliding rod can slide up and down in the sliding groove, and the sliding rod drives the baffle to move up and down on the side of the processing table. There is a gap between the sliding rod and the sliding groove, and the sliding rod can move horizontally in the sliding groove. The baffle is provided with a protrusion on the side near the processing table. When the baffle moves upward and the protrusion is higher than the top surface of the processing table, the baffle moves horizontally, and the protrusion rests on the upper surface of the processing table to fix the baffle.
[0012] By adopting the above technical solution, the baffle structure is simpler and more durable.
[0013] Preferably, the cross-section of the through groove near the bottom of the rotating seat is enlarged to form a mounting groove, and the cutting blade is engaged in the mounting groove, which provides the cutting blade with a supporting force in the rotation direction.
[0014] Without a mounting slot, when the rotating seat drives the entire cutting blade to rotate and cut, the sidewall of the capped bolt is tightly against the inner side of the through slot, and the capped bolt provides support for the cutting blade in the direction of rotation. By adopting the above technical solution, the mounting slot can hold the cutting blade in place, drive the cutting blade to rotate, reduce the tangential force on the capped bolt installed on the cutting blade, prevent the capped bolt from loosening, and enhance the overall structural stability.
[0015] Preferably, the mounting groove is square, and the upper part of the cutting blade matches the shape of the mounting groove. After unscrewing the nut on the top of the cutting blade, the cutting blade can be pulled downwards directly to complete the quick disassembly of the cutting blade.
[0016] By adopting the above technical solution, after removing the capped bolt, the cutting blade can be pulled directly downwards from the mounting groove, making the disassembly process more convenient and faster.
[0017] Preferably, a handle is provided on the outer side of the baffle.
[0018] By adopting the above technical solution, it is convenient to pull the baffle.
[0019] Preferably, the clamping assembly includes a support plate disposed on the upper surface of the processing table and a plurality of clamping blocks disposed on the support plate. The installation position of the clamping blocks on the support plate is adjustable. The pipe to be processed is placed on the support plate, and the plurality of clamping blocks clamp and fix the pipe to be processed from the side.
[0020] By adopting the above technical solution, the clamping block can be adjusted to fix pipes of different sizes.
[0021] Preferably, a chip collection box is provided at the bottom of the processing table, and multiple chip discharge holes are provided through the processing table along its thickness direction. The chip discharge holes correspond to the internal space of the chip collection box, and the chips fall into the chip collection box through the chip discharge holes.
[0022] By adopting the above technical solutions, debris can be collected, improving the cleanliness of the processing environment and reducing the interference of debris on equipment operation.
[0023] Preferably, the processing table is also provided with an air blowing pipe, the air outlet of which faces the finishing area of the pipe to be processed, for blowing away debris generated during the finishing process.
[0024] By adopting the above technical solutions, the interference of debris on equipment operation during the finishing process can be reduced.
[0025] Preferably, the upper surface of the rotating seat is provided with scale lines along the direction of the through groove, and the scale lines indicate the distance from the corresponding position to the center of the rotating seat.
[0026] By adopting the above technical solution, the position of the cutting blade can be displayed intuitively, making it convenient to adjust the position of the cutting blade according to the preset size.
[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustable cutting blade enables fine finishing of pipe openings with different inner diameters. Furthermore, the cutting blade position can be quickly adjusted via the through groove and cap bolt on the rotating seat, making it more convenient to use. 2.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.
[0031] This application discloses a device for precision repair of pipe openings.
[0032] Reference Figure 1 and 2 A pipe end finishing device includes a work platform 1, on which a processing table 11 and a support frame 12 are mounted. A clamping assembly 7 is mounted on the processing table 11. A pipe 8 to be finished is vertically mounted on the processing table 11, and the bottom of the pipe 8 is detachably fixed by the clamping assembly 7. A rotating seat 6 is rotatably mounted on the support frame 12, positioned above the pipe 8. A cutting blade 63 is mounted on the bottom of the rotating seat 6. The cutting blade 63 cuts the pipe end of the pipe 8 to eliminate burrs and bumps on the sidewall of the pipe end, thus finishing the pipe. A through groove 61 is radially formed at the bottom of the rotating seat 6. A threaded hole is formed at the upper part of the cutting blade 63, and a capped bolt 64 is threaded into the threaded hole. The capped bolt 64 extends from the upper end of the through groove 61 into the through groove 61 and is threadedly connected to the upper part of the cutting blade 63. The upper part of the cutting blade 63 is wider than the width of the through groove 61. When the cap bolt 64 is tightened, the bolt head of the cap bolt 64 rests against the upper part of the through groove 61, and the upper part of the cutting blade 63 rests against the lower part of the through groove 61. The tightening force of the cap bolt 64 and the cutting blade 63 fixes the cutting blade 63 in place under the through groove 61. The cutting blade 63 can move along the through groove 61, thus making it suitable for pipes of different sizes, and the entire device has greater applicability.
[0033] Reference Figure 1 and 2The processing table 11 is detachably mounted on the work platform 1 via a support structure. The bottom of the processing table 11 is suspended, and a chip collection box 113 is provided at the bottom of the processing table 11. Multiple chip removal holes 111 are formed through the processing table 11 along its thickness direction. The chip removal holes 111 are connected to the internal space of the chip collection box 113, and the chips fall into the chip collection box 113 through the chip removal holes 111. An air blowing pipe 112 is also provided on the processing table 11. The air outlet of the air blowing pipe 112 faces the finishing area of the pipe 8 to be processed, and is used to blow away the chips generated during the finishing process.
[0034] Reference Figure 2 and 3 A support frame 12 is disposed on the side of the processing table 11. The support frame 12 also includes a lifting assembly 2 and a rotating assembly 3 for driving the rotating seat 6. The lifting assembly 2 drives the rotating seat 6 to rise and fall, and the rotating assembly 3 drives the rotating seat 6 to rotate. The lifting assembly 2 includes a mounting plate 121 and a lead screw module 23. The mounting plate 121 is slidably connected to the support frame 12. The lifting assembly 2 also includes two guide rails 21 and a slide block 22 mounted on the guide rails 21. The guide rails 21 are vertically fixed to the support frame 12, and the slide block 22 is fixed to the mounting plate 121. The lead screw module 23 drives the mounting plate 121 to move vertically on the support frame 12. The rotating assembly 3 includes a bearing 31 rotatably disposed on the mounting plate 121 and a rotating motor 32 for driving the bearing 31 to rotate. The rotating seat 6 is disposed at the bottom of the bearing 31 and rotates with the bearing 31. In some embodiments, the rotating seat 6 is detachably disposed at the bottom of the bearing 31, and different rotating seats 6 can be replaced according to different processing requirements.
[0035] Reference Figure 2 and 3 The work platform 1 is covered by an outer shell 4, and the processing table 11 and the support frame 12 are both covered inside the outer shell 4. The top surface and three sides of the outer shell 4 are closed. A window is opened on the side of the outer shell 4 away from the support frame 12 for replacing the pipe 8 to be processed and the cutting blade 63. A baffle 41 is provided between the processing table 11 and the window. The baffle 41 can be moved in the vertical direction to cover or open the window.
[0036] Reference Figure 3A vertical sliding rod 42 is provided on the baffle 41. A sliding groove 43 is provided on the side of the processing table 11 near the baffle 41. The sliding groove 43 is located on the processing table 11, and the sliding rod 42 can slide up and down within the sliding groove 43, causing the baffle 41 to move up and down on the side of the processing table 11. A gap 45 is left between the sliding rod 42 and the sliding groove 43. The sliding rod 42 can move horizontally within the sliding groove 43. Unlike conventional up-and-down sliding, in this embodiment, the gap 45 between the sliding rod 42 and the sliding groove 43 is relatively large, allowing the sliding rod 42 to not only slide up and down but also move horizontally within the sliding groove 43, enabling the baffle 41 to move closer to or further away from the processing table 11 within a certain range. A protrusion 44 is provided on the side of the baffle 41 near the processing table 11. The protrusion 44 is located at the lower part of the baffle 41, allowing it to move closer to or further away from the processing table 11. When it is necessary to raise the baffle 41 to block the window, the baffle 41 moves upward until the protrusion 44 is higher than the upper surface of the processing table 11. Then, the lower end of the baffle 41 is pushed forward so that the protrusion 44 rests on the upper surface of the processing table 11. The processing table 11 can then support the baffle 41, thus fixing the baffle 41 in place. When it is necessary to lower the baffle 41, simply pull the lower part of the baffle 41 to disengage the protrusion 44 from the processing table 11. The protrusion 44 on the baffle 41 loses the support of the processing table 11, and the baffle 41 can be lowered smoothly. When the protrusion 44 rests on the upper surface of the processing table 11, because the center of gravity of the baffle 41 is higher, the baffle 41 is tilted as a whole. The lower end of the baffle 41 is closer to the processing table 11, and the upper end is farther away from the processing table 11, allowing the protrusion 44 to rest more stably on the processing table 11.
[0037] Reference Figure 4 and 5 The cross-section of the through groove 61 near the bottom of the rotating seat 6 widens to form a mounting groove 62. The cutting blade 63 is engaged in the mounting groove 62, which provides lateral force to the cutting blade 63. The mounting groove 62 is square, and the upper shape of the cutting blade 63 matches the mounting groove 62. After unscrewing the cap bolt 64 on the top of the cutting blade 63, the cutting blade 63 can be pulled downwards, completing the quick disassembly of the cutting blade 63. In some other embodiments, unlike this embodiment, the mounting groove 62 is T-shaped, and the upper shape of the cutting blade 63 matches the mounting groove 62. The special shape of the mounting groove 62 supports the cutting blade 63, preventing it from falling downwards after being engaged in the mounting groove 62. In this embodiment, the cap bolt 64 does not need to bear the weight of the cutting blade 63, and the cap bolt 64 is less likely to loosen. The upper surface of the rotating seat 6 has scale lines along the direction of the through groove 61, and the scale lines indicate the distance from the corresponding position to the center of the rotating seat 6.
[0038] Reference Figure 4 and 5When performing fine finishing on the pipe opening, the lower part of the cutting blade 63 extends into the inner wall of the pipe 8 to be processed, and the cutting tip of the cutting blade 63 is in contact with the inner wall of the pipe 8 to be processed. The pipe opening is then rotated to cut. Alternatively, a cutting blade 63 with its cutting tip pointing inward can be installed on the rotating base 6. By adjusting the position of the cutting blade 63 on the support plate 71, the cutting tip is made to contact the outer wall of the pipe 8 to be processed. The outer wall of the pipe opening is then cut by rotating to perform fine finishing on the pipe opening of the pipe 8 to be processed. A washer is provided between the bolt head of the cap bolt 64 and the rotating base 6 to increase friction.
[0039] Reference Figure 6 and 7 The clamping assembly 7 includes a support plate 71 disposed on the upper surface of the processing table 11 and a plurality of clamping blocks 73 disposed on the support plate 71. The pipe to be processed 8 is placed on the support plate 71, and the plurality of clamping blocks 73 clamp and fix the pipe to be processed 8 from the side. The bottom of the support plate 71 has three fixing grooves 72 arranged in a circular array, and the length direction of the three fixing grooves 72 is arranged radially along the support plate 71. The cross-section of the fixing groove 72 is an I-shaped groove that is wider at the top and bottom and narrower in the middle. The clamping block 73 is clamped on the upper side of the fixing groove 72, and the threaded fixing block 74 is clamped on the lower side of the fixing groove 72. Both the clamping block 73 and the threaded fixing block 74 can slide along the fixing groove 72, and both the clamping block 73 and the threaded fixing block 74 have threaded holes. The clamping assembly 7 also includes a bolt 75, which passes through the upper end of the clamping block 73 and enters the fixing groove 72, and is threadedly connected to the threaded fixing block 74 on the lower side of the fixing groove 72. The tightening force of the bolt 75 clamps the support plate 71 between the clamping block 73 and the threaded fixing block 74. By adjusting the position of the clamping block 73 within the fixing groove 72, the three clamping blocks 73 can clamp the pipe 8 to be processed from different directions. Furthermore, the fixed position of the clamping block 73 within the fixing groove 72 is adjustable, allowing the clamping block 73 to clamp pipes 8 of different sizes to be processed.
[0040] The implementation principle of this embodiment is as follows: The bottom of the pipe 8 to be processed is fixed on the processing table 11, and the side wall of the pipe opening at the top of the pipe 8 is cut by the rotating cutting blade 63 to perform fine finishing on the pipe opening. The cutting blade 63 is fixed to the rotating seat 6 by a cap bolt 64 and a through groove 61. When processing pipes with different inner diameters, the cap bolt 64 can be loosened, and the distance between the cutting blade 63 and the center of the rotating seat 6 can be adjusted along the through groove 61. The rotating seat 6 is rotatably mounted on the mounting plate 121, and the entire mounting plate 121 is slidably mounted on the support frame 12. The screw module 23 drives the mounting plate 121 to slide up and down along the guide rail 21, while simultaneously driving the rotating seat 6 to cut the side wall of the pipe opening from top to bottom. The cutting blade 63 can continuously descend while rotating and cutting the pipe 8 to be processed, making it suitable for pipes of different heights. During the finishing process of the pipe 8 to be processed, debris is generated. Therefore, the finishing process is carried out in the outer casing 4. A window is provided on the side of the outer casing 4. A baffle 41 that can be quickly opened and closed is provided in the window. When the pipe needs to be finished, the baffle 41 is raised so that the protrusion 44 on the back of the baffle 41 is locked on the processing table 11 to fix the baffle 41 and prevent the debris generated during the finishing process of the pipe 8 to be processed from flying out. When the cutting blade 63 needs to be adjusted, the baffle 41 can be moved down to open the window.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
