[0002] Currently, such as Figure 4 As shown, welding T-shaped aviation pipes requires forming an arc-shaped cut on one pipe that matches the outer contour of the other pipe. Traditional cutting methods mostly involve manual cutting with a grinding wheel. However, manual operation makes it difficult to precisely control the cutting path and force, often resulting in irregular cuts at the pipe ends, requiring further trimming and affecting the welding quality of the pipes.

[0003] In addition, the processing of the arc-shaped cut at the end of the pipeline relies on manual operation, which is time-consuming and labor-intensive, increases the workload of operators, and is prone to operational errors. Cutting accuracy is difficult to guarantee, which reduces production efficiency.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0016] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0017] This invention effectively avoids the technical problems of relying on manual operation for processing the arc-shaped cut at the end of aviation pipelines in the prior art, which is time-consuming, labor-intensive, increases the workload of operators, is prone to operational errors, makes it difficult to guarantee cutting accuracy, and reduces production efficiency. This invention provides an aviation pipeline cutting device, including a frame, a drive mechanism, and a cutting mechanism. The cutting mechanism includes a cutting base, a first cutting piece, and a second cutting piece. The cutting base is mounted on the base plate of the frame and has a positioning groove for mounting the first cutting piece.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] like Figures 1 to 3 As shown, this utility model provides an aviation pipeline 10 cutting device, including a frame 1, a drive mechanism, and a cutting mechanism. The cutting mechanism includes a cutting base 3, a first cutting piece 4, and a second cutting piece 5. The cutting base 3 is mounted on the base plate 101 of the frame 1, and a positioning groove 301 is provided on the cutting base 3 for mounting the first cutting piece 4. A cutting groove 401 is provided on the first cutting piece 4, and a placement groove 402 adapted to the outer contour of the pipeline 10 is provided on the cutting groove 401. A cutting block 504 is provided on the second cutting piece 5, and the cutting block 504 is adapted to the pipeline 10 so that the pipeline 10 can be fitted onto the cutting block 504. The drive mechanism is mounted on the top plate 102 of the frame 1 and connected to the second cutting piece 5, for driving the second cutting piece 5 to move the cutting block 504 closer to or away from the cutting groove 401.

[0038] The cutting block 504 of this invention is adapted to the pipe 10, enabling the pipe 10 to be accurately fixed on the cutting block 504, providing stable support for subsequent precise cutting. Simultaneously, the placement groove 402 of the first cutting piece 4 is adapted to the outer contour of the pipe 10. When the pipe 10 moves into the placement groove 402 along with the cutting block 504, it can be further precisely positioned, ensuring accurate positioning of the pipe 10 during the cutting process. During the cutting process, the cutting block 504 and the cutting groove 401 cooperate with each other, and under the stable drive of the driving mechanism, the cutting path can be precisely controlled, thereby forming a compliant arc-shaped cut 1001 on the pipe 10, effectively improving cutting accuracy and ensuring the processing quality of the pipe 10.

[0039] Throughout the entire cutting process, the operator only needs to install the pipe 10 onto the cutting block 504 and start the drive mechanism, which reduces the probability of operational errors caused by human factors, improves the stability and reliability of production, and eliminates the need for continuous high-intensity physical labor, thus reducing work intensity.

[0040] Furthermore, the drive mechanism includes an electric actuator 2.

[0041] The following steps constitute one cycle of setting, positioning, and cutting the pipe 10: First, set the pipe 10 to be cut onto the cutting block 504 of the second cutting piece 5. Since the cutting block 504 is compatible with the pipe 10, the pipe 10 can be accurately fixed on the cutting block 504, improving the stability of the pipe 10 during the cutting process.

[0042] Subsequently, the electric push rod 2 is activated, and it begins to work, driving the second cutting piece 5 to move the cutting block 504 downwards. As the cutting block 504 moves, the pipe 10 fitted on it also moves downwards until the pipe 10 moves into the placement groove 402 of the first cutting piece 4. The placement groove 402 is adapted to the outer contour of the pipe 10, enabling further precise positioning of the pipe 10.

[0043] Then, the electric push rod 2 continues to drive the second cutting piece 5 to move the cutting block 504 downward. At this time, the cutting block 504 cooperates with the cutting groove 401 of the first cutting piece 4, and cuts the pipe 10 located in the cutting groove 401 by the pressure of the electric push rod 2, so as to form an arc-shaped cut 1001 on the pipe 10.

[0044] Using the cutting device of this invention, only two of the above-mentioned cycles are needed to obtain a weldable pipe 10.

[0045] As an optional implementation, the first cutting member 4 is a cylindrical structure, and the cutting groove 401 is a circular groove that extends through the first cutting member 4 along its axial direction.

[0046] The cutting groove 401 provides space for the movement of the second cutting piece 5 and the cutting block 504.

[0047] As an optional implementation, the cutting base 3 is provided with a positioning screw hole 302, which is provided radially through the cutting base 3. The positioning screw passes through the positioning screw hole 302 and abuts against the outer wall surface of the first cutting piece 4.

[0048] After the positioning screw passes through the positioning screw hole 302, it abuts against the outer wall surface of the first cutting part 4, which can easily make fine adjustments and fix the first cutting part 4, improving the flexibility and adjustability of the device.

[0049] As an optional implementation, the cutting mechanism also includes a mounting base 6, which is adjustablely connected to the base plate 101 and is used to mount the cutting base 3.

[0050] As an optional implementation, the mounting base 6 has U-shaped adjustment grooves 601 on both sides, and the base plate 101 has connection holes. The adjustment screw 7 passes through the limiting nut 8, the adjustment grooves 601 and the connection holes.

[0051] As an optional implementation, the width of the adjusting groove 601 is greater than the outer diameter of the adjusting screw 7, and the outer diameter of the limiting nut 8 is greater than the width of the adjusting groove 601.

[0052] Because the width of the adjusting groove 601 is greater than the outer diameter of the adjusting screw 7, the adjusting screw 7 has a certain amount of room to move within the adjusting groove 601. Since the outer diameter of the limiting nut 8 is greater than the width of the adjusting groove 601, the adjusting screw 7 applies pressure to the limiting nut 8 so that the limiting nut 8 can press against the surface of the mounting base 6, fixing the mounting base 6 to the base plate 101 and preventing the mounting base 6 from moving freely again after adjustment.

[0053] By adjusting the position of the screw 7 in the adjustment groove 601, the position of the mounting base 6 relative to the substrate 101 can be changed, thereby achieving fine adjustment of the positions of the cutting base 3 and the first cutting piece 4.

[0054] As an optional implementation, the second cutting member 5 has a first flat surface 501, a first arc surface 502, a second flat surface and a second arc surface 503 connected in sequence, and the cutting block 504 is respectively installed on the first flat surface 501 and the second flat surface; the first arc surface 502 and the second arc surface 503 are adapted to the cutting groove 401.

[0055] Furthermore, the cutting block 504 is positioned at the midpoint between the first flat surface 501 and the second flat surface.

[0056] When the pipe 10 is fitted onto the cutting block 504, the end face of the pipe 10 abuts against the first flat surface 501 or the second flat surface, so that the installation position of the pipe 10 on the cutting block 504 is accurate and no displacement along the axial direction of the pipe 10 occurs during the cutting process.

[0057] The first arc surface 502 and the second arc surface 503 are adapted to the cutting groove 401, so that the second cutting piece 5 can improve the stability of the cutting path by sliding with the cutting groove 401 during the movement.

[0058] As an optional implementation, the cutting block 504 has a disc-shaped structure and its outer wall surface is an arc surface, which is adapted to the cutting groove 401. The outer edge of the cutting block 504 is a sharp blade 5041.

[0059] Furthermore, the outer wall surfaces of the two sets of cutting blocks 504, together with the first arc surface 502 and the second arc surface 503, form a circular structure that is compatible with the cutting groove 401.

[0060] The thickness of the upper and lower parts of the cutting block 504 gradually decreases from the outer edge to the center, so that its outer edge forms a blade 5041 and there is a gap between it and the first flat surface 501 or the second flat surface.

[0061] The disc-shaped structure and arc-shaped surface design allow the cutting block 504 to better cooperate with the cutting groove 401, improving cutting stability. During the cutting process, the blade 5041 contacts the pipe 10, and cutting is achieved by the pressure of the electric push rod 2.

[0062] As an optional implementation, the second cutting piece 5 is connected to the telescopic rod 201 of the electric push rod 2 via a threaded sleeve 9. An external thread section 2011 is provided on the outer wall of the telescopic rod 201, and an internal thread section 901 adapted to the external thread section 2011 is provided on the inner wall of the threaded sleeve 9.

[0063] The telescopic rod 201 of the electric push rod 2 is connected to the threaded sleeve 9 by the screw connection between the external thread section 2011 and the internal thread section 901.

[0064] When the electric push rod 2 is activated, the telescopic rod 201 will move in a straight line. Through the connection of the threaded sleeve 9, it will drive the second cutting piece 5 and the cutting block 504 to move up and down, thereby realizing the action of the cutting block 504 moving closer to or away from the cutting groove 401 and completing the cutting of the pipe 10.
