[0002] Aviation pipe fittings are connecting structures between complex pipeline structures in the aerospace field, or between pipelines and components. Commonly used three-way fittings are all "T"-shaped structures. When turning aviation pipe fittings with "T"-shaped structures, fixtures are required for alignment and positioning.

[0003] Existing fixtures for machining aviation pipe joints, such as the authorized utility model patent with publication number CN218800529U, entitled A fixture for machining aviation pipe joints, only use two sets of locking components similar to bolts to squeeze and fix the pipe joint to be machined and the mandrel, which is not only insufficient in stability, but also unable to quickly center the pipe joint to be machined, requiring repeated measurement and debugging. In view of the above problems, an innovative design is made based on the original fixture for machining aviation pipe joints. Utility Model Content

[0030] See also Figure 1-5 The utility model provides a technical solution: a fixture for machining aviation pipe joints, including a base plate 1, a base 2, a through hole 3, a side locking hole 4, a track groove 5, an adjustment threaded rod 6, a side movable plate 7, a positioning hole 8, a locking rod 9, a locking nut 10, a horizontal threaded rod 11, a positioning nut 12, a stabilizing hole 13, a back movable plate 14 and a core rod 15, a base 2 is fixedly mounted on one end of the top surface of the base plate 1, a through hole 3 is opened in the middle of the base 2, and side locking holes 4 are opened in the middle and top of the side wall of the through hole 3;

[0031] A track groove 5 is provided at one end edge of the top surface of the base plate 1, and an adjusting threaded rod 6 is installed in the track groove 5 through the bearing seat, and the adjusting threaded rod 6 is threadedly connected with the bottom end of the side movable plate 7, and a positioning hole 8 is provided at the top of the side movable plate 7, and a locking rod 9 is installed in the positioning hole 8, and a locking nut 10 is installed at one end of the locking rod 9, and the other end of the locking rod 9 is in contact with the inner wall of the side locking hole 4;

[0032] A horizontal threaded rod 11 is fixed to the other end of the top surface of the base plate 1 . The horizontal threaded rod 11 passes through a stabilizing hole 13 . The stabilizing hole 13 is opened at the bottom end of a back movable plate 14 . A core rod 15 is fixedly installed on the top of the back movable plate 14 .

[0033] In this example, the spiral directions of the threads on both sides of the center of the adjusting threaded rod 6 are opposite, and side movable plates 7 are symmetrically installed at both ends of the adjusting threaded rod 6. The above-mentioned structural design enables the adjusting threaded rod 6 to use the threads with opposite spiral directions on both sides of the center to drive the side movable plates 7 symmetrically distributed at both ends to move in different directions at the same speed when rotating.

[0034] The adjusting threaded rod 6 in this example is symmetrically distributed about the center of the side movable plate 7, and the bottom end of the side movable plate 7 is slidably connected to the track groove 5. The above structural design enables the adjusting threaded rod 6 to drive the side movable plate 7 to perform stable linear sliding displacement along the track groove 5.

[0035] In this example, the locking rod 9 is slidably connected to the positioning hole 8 and the side locking hole 4. The locking rod 9 is provided with threads only at the connecting part with the locking nut 10. The locking nuts 10 are symmetrically distributed with respect to the positioning hole 8. The above structural design enables the locking rod 9 to move stably along the positioning hole 8 and the side locking hole 4. The locking nut 10 can quickly fix the locking rod 9 by squeezing the side surfaces of the side movable plates 7 at both ends of the positioning hole 8, which is convenient for the debugging of the locking rod 9.

[0036] In this example, the horizontal threaded rod 11 is slidably connected to the stable hole 13. The horizontal threaded rod 11 and the stable hole 13 are both symmetrically distributed about the center of the back movable plate 14. The above structural design enables the back movable plate 14 to move horizontally in a straight line along the horizontal threaded rod 11 with the stable hole 13.

[0037] A positioning nut 12 is installed at the end of the horizontal threaded rod 11 in this example. The positioning nut 12 is in contact with the bottom surface of the side of the back movable plate 14 away from the base 2. The bottom surface of the back movable plate 14 is in contact with the top surface of the substrate 1. The above structural design ensures that the back movable plate 14 can move stably along the substrate 1, and the positioning nut 12 can stably squeeze the back movable plate 14, so that the mandrel 15 at the top of the back movable plate 14 is in stable contact with the base 2.

[0038] Working principle: Before using this device, first Figure 4 Rotate the symmetrically distributed locking nuts 10 away from both sides of the side movable plate 7, and push the locking rod 9 to slide horizontally along the positioning hole 8 and the side locking hole 4 until the distances from the ends of the symmetrically distributed locking rods 9 to the center of the base 2 are the same. Then rotate the symmetrically distributed locking nuts 10 to reset and squeeze both sides of the side movable plate 7 to fix them;

[0039] Subsequently, insert the pipe joint to be processed horizontally into the through hole 3 in a "丄" posture. At the same time, rotate the symmetrically distributed adjusting threaded rods 6 in the same direction. The adjusting threaded rods 6 use the thread connection relationship to drive Figure 3 the symmetrically distributed side movable plates 7 in the [description] to drive the locking rod 9 to slide horizontally along the track groove 5. The symmetrically distributed locking rods 9 slide into the side locking holes 4 to horizontally squeeze the pipe joint to be processed in the through hole 3. When the pipe joint to be processed is fixed, stop rotating the adjusting threaded rod 6, and use the thread self-locking to fix the positions of the side movable plate 7 and the locking rod 9; Figure 4 Then push

[0040] Then push Figure 5The back movable plate 14 with the stabilizing hole 13 slides horizontally to the left along the horizontal threaded rod 11 until the end of the mandrel 15 installed on the top of the back movable plate 14 is inserted into the through hole 3 and connected with the pipe joint to be processed. The shaft shoulder of the mandrel 15 fits tightly with the right side of the base 2. The positioning nut 12 is rotated to move left to squeeze the bottom side of the back movable plate 14, and the mandrel 15 is connected and fixed to the base 2, and the fixed pipe joint can be machined;

[0041] After the processing is completed, it is only necessary to rotate the positioning nut 12 away from the back movable plate 14, move the back movable plate 14 with the core rod 15 horizontally away from the base 2, and rotate the adjusting threaded rod 6 in the opposite direction to make the symmetrically distributed side movable plates 7 with the locking rod 9 away from the pipe joint in the through hole 3, and the processed pipe joint can be taken out.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
