That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic adjustment device for an aluminum tube of the utility model comprises an aluminum tube 2 and a base plate 1, wherein the aluminum tube 2 is arranged at the upper end of the base plate 1, and both ends of the aluminum tube 2 are provided with positioning rings 3 for pressing the aluminum tube 2 inwardly, and a positioning frame 4 is provided inside the positioning ring 3, and an adjustment block 17 is provided in the positioning frame 4, and an arc-shaped socket is provided on the adjustment block 17, and a load-bearing plate 5 is inserted into the opposite socket, and the outer side surface of the load-bearing plate 5 contacts the inner wall surface of the aluminum tube 2, and an electric push rod 16 is installed on the bottom surface inside the positioning frame 4, and the piston rod of the electric push rod 16 is installed on the bottom surface of the adjustment block 17, and a driving mechanism for driving the aluminum tube 2 to rotate and a limiting mechanism for driving the positioning ring 3 to move inward are installed on the base plate 1.

[0020] In this embodiment, the driving mechanism includes a reduction motor 15, a plurality of fixed plates 14 and a plurality of driving rollers 13. The driving rollers 13 are arranged in parallel above the base plate 1. The aluminum tube 2 is placed between the driving rollers 13. Fixed plates 14 are provided at both ends of the driving roller 13. The lower ends of the fixed plates 14 are installed on the bottom surface of the base plate 1. Bearings are embedded on the opposite surfaces of the fixed plates 14. The roller shafts at both ends of the driving roller 13 are installed in the inner rings of the bearings. The reduction motor 15 is installed on one of the reduction motors 15. The rotating shaft of the reduction motor 15 passes through the fixed plate 14 and is fixedly connected to the roller shaft at one end of the driving roller 13.

[0021] In this embodiment, the limiting mechanism includes a bidirectional linear slide 9, which is axially installed in the middle of the surface of the base plate 1. A fixed seat 11 is installed on the moving platform of the bidirectional linear slide 9. The upper end of the fixed seat 11 is installed on the bottom surface of the positioning ring 3. A support column 12 is also installed on the fixed seat 11. A servo motor 8 is installed on the upper end of the support column 12. A fixed table 7 is installed on the rotating shaft of the servo motor 8, and the fixed table 7 is installed on the outer surface of the positioning frame 4.

[0022] In this embodiment, the load-bearing plate 5 is covered with screw holes 18, and the screw holes 18 of the load-bearing plate 5 located on the outside of the positioning ring 3 are all threadedly connected with fixing bolts 6. The fixing bolts on both sides can restrict the load-bearing plate to the outside of the positioning ring, thereby preventing the load-bearing plate from falling due to axial movement and increasing stability after installation.

[0023] In this embodiment, the load-bearing plate 5 is made of steel material, which increases the firmness and bearing capacity of the aluminum tube and can provide better support for the aluminum tube.

[0024] During processing, the aluminum tube is placed between the driving rollers and the bidirectional linear slide is started, so that the moving platform on the bidirectional linear slide moves inward synchronously. The movement of the moving platform drives the fixed seat and the positioning ring until the positioning ring contacts the two ends of the aluminum tube, thereby effectively limiting the axial position of the aluminum tube.

[0025] After the above is completed, the reduction motor can be started. The start of the reduction motor drives the driving roller, and the friction between the driving roller and the aluminum tube can drive the aluminum tube to rotate, thereby adjusting the opening position of the aluminum tube. After the position drive, the bidirectional linear slide is started again, so that the positioning ring can press the two ends of the aluminum tube, thereby clamping the aluminum tube in place and avoiding affecting the stability of the drilling.

[0026] In order to avoid the concave situation during the drilling process, a bearing plate can be inserted into the socket, and the position of the bearing plate can be adjusted according to the position of the drilling hole. During the adjustment, the servo motor is started, and the start of the servo motor drives the positioning frame to rotate inside the positioning ring. The rotation of the positioning frame drives the bearing plate until the bearing plate is moved to the drilling position, and the bearing plate can provide support for the drilling position;

[0027] Among them, since the height of the load-bearing plate can be adjusted, it can adapt to aluminum tubes with different inner diameters. During adjustment, the electric push rod can be started to extend or retract the piston rod of the electric push rod. The movement of the piston rod drives the adjustment block and the load-bearing plate until the outer side surface of the load-bearing plate contacts the inner wall surface of the aluminum tube to adapt to aluminum tubes with different diameters.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
