[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-6 As shown, this utility model is an aluminum tube interface inner wall trimming device, comprising:

[0026] The trimming mechanism includes a trimming rod 21. The trimming rod 21 has a first slot 22 and a second slot 24 on its upper and lower opposite sides on its outer surface. A movable block 23 is slidably connected in the first slot 22, and the upper end face of the movable block 23 is arc-shaped. A threaded rod 25 is threadedly connected to one end of the second slot 24, and a movable rod 26 is fixed to one side of the surface of the threaded rod 25. The inner wall of the first slot 22 has grooves 27 on opposite sides, and the movable block 23 has protrusions 28 on both sides, with the protrusions 28 extending into the grooves 27 and the two slidably connected.

[0027] The trimming rod 21 provides an overall structural installation environment and, together with the movable block 23, forms a complete cylindrical structure for trimming the arc of the aluminum tube interface. The first slot 22 receives the movable block 23 and allows it to move. With the help of the forward movement, the movable block 23 can trim the concavity of the inner wall of the aluminum tube interface. The second slot 24 receives and installs the movable rod 26 with the help of the threaded rod 25. The movable rod 26 unfolds and abuts against the contact surface to provide the support force required for the operation of the movable block 23. The position adjustment and guidance of the movable block 23 are achieved by the sliding of the protrusion 28 in the groove 27.

[0028] Working principle: During the adjustment of the aluminum tube interface, the movable block 23 is moved forward in advance. The part of the first slot 22 that is moved outward can be used to move the inner wall recess of the aluminum tube interface outward. At this time, the above-mentioned directional operation steps are applied to restore the movable block 23 to its original position. When applying the above operation steps, the movable rod 26 needs to be applied and unfolded under the screw rotation. The structural support force is provided by the abutment between the movable rod 26 and the contact surface. Then, the entire cylindrical adjustment rod 21 is extended into the aluminum tube interface, and the rotation force is applied to adjust the arc of the aluminum tube interface.

[0029] This solution integrates multiple repair methods for aluminum tube interfaces, eliminating the need to change multiple tools, saving time and effort, and significantly improving the effectiveness and efficiency of the operation.

[0030] Please see Figure 1-6 As shown, this embodiment is based on the above embodiment:

[0031] It also includes a positioning mechanism, which includes a fixed positioning frame 31 and a movable positioning frame 32; a guide frame 33 is fixed in the middle of both sides of the fixed positioning frame 31, and a guide block 35 is slidably connected in the middle of the upper end of the guide frame 33. There are two guide blocks 35, and the inner sides of the two guide blocks 35 are fixed to one end of both sides of the movable positioning frame 32.

[0032] The fixed positioning frame 31 and the movable positioning frame 32 work together to position the aluminum tube to be repaired, while the guide block 35 achieves multi-position movement and adjustment of the movable positioning frame 32 by sliding on the guide frame 33.

[0033] A rubber block 37 is fixed to one end inside the guide frame 33, and the rubber block 37 is in contact with one side of the guide block 35.

[0034] The rubber block 37 contacts the sliding guide block 35 to provide anti-collision protection.

[0035] The bottom end of the guide frame 33 is fixed with a hole block 310, and the middle of the hole block 310 is internally threaded with a locking pin 311;

[0036] The hole block 310 uses the locking pin 311 to abut against the upper end of the support base 11 to ensure the stability of the fixed positioning frame 31 structure after the position is adjusted by rotation.

[0037] One end of the guide frame 33 is connected to a movable spring 34, and one end of the movable spring 34 is a protruding post. The upper end of the guide frame 33 is fixed with a positioning block 38 above the movable spring 34, and a cross hole is passed through the middle of the positioning block 38. The other side of the guide block 35 is fixed with horizontal posts 36 at the top and bottom. The upper horizontal post 36 extends into the cross hole, and a positioning post 39 is fitted in the cross hole and extends into the upper horizontal post 36. The lower horizontal post 36 is in contact with the other end of the movable spring 34.

[0038] The protruding column connects the movable spring 34 to the guide frame 33. With the help of the elastic force of the movable spring 34, the sliding guide block 35 can be protected against collision again. After the deformation is restored, a reverse force can be applied to complete the sliding displacement of the guide block 35 with little effort. The horizontal column 36 achieves the above-mentioned protective collision effect by contacting the movable spring 34. On the other hand, it works with the positioning block 38 and the positioning column 39 to fix the movable positioning frame 32 after the cover is closed.

[0039] It also includes a support mechanism, which includes a support base 11; the upper middle part of the support base 11 is provided with a bearing 12, and the middle part of the bearing 12 is fitted with a support column 13, the upper end of the support column 13 is fixed to the middle part of the bottom end of the fixed positioning frame 31.

[0040] The support base 11 provides structural installation and support capabilities. The fixed positioning frame 31 is installed via the support column 13 through the bearing base 12, and the bearing base 12 is used to meet multi-angle adjustment.

[0041] A positioning ring 14 is fixed to the lower part of the outer surface of the bearing seat 12, and the positioning ring 14 is fixed to the upper end of the support seat 11 by positioning bolts that pass through the middle at equal intervals.

[0042] The positioning bolts fix the positioning ring 14, and the fixed positioning ring 14 satisfies the installation of the shaft seat 12 structure.

[0043] Working principle: During the positioning and adjustment of the aluminum tube interface, the movable positioning frame 32 is pre-acted. With the help of the guide block 35 sliding in the guide frame 33, the fixed positioning frame 31 and the movable positioning frame 32, which are in the closed state, are separated. After the corrected aluminum tube is placed into the fixed positioning frame 31, the above-mentioned directional operation steps are applied to close the two again. The structure of the fixed positioning frame 31 and the movable positioning frame 32 in the closed state is limited by the interlocking of the cross hole and the positioning post 39.

[0044] This solution allows for simple and convenient loading and unloading of aluminum tubes before and after trimming. Furthermore, the unloading process can be completed effortlessly with the help of the elastic force of the movable spring 34, further improving the performance.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
