[0020] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a marking tool for aluminum tube processing, comprising a processing table 1, a fixed seat 2 is provided on the upper surface of the processing table 1, and at least two pipe-penetrating openings 3 are penetrated at the lower end of the fixed seat 2. Preferably, the number of the pipe-penetrating openings 3 is five, and the five pipe-penetrating openings 3 are evenly distributed at the lower end of the fixed seat 2. By providing five pipe-penetrating openings 3, five aluminum tubes can be marked at the same time, which greatly improves the marking efficiency of the aluminum tubes. A bearing ring 4 is provided on the upper surface of the fixed seat 2, and the rotating shaft 5 is rotatably connected in the bearing ring 4 and there is damping between the rotating shaft 5 and the bearing ring 4. The first and second slides 9 and 12 are slidably connected in the side slides 8. There is damping between the first and second slides 9 and 12 and the side slides 8 to ensure that the first and second slides 9 and 12 are not prone to sliding when no force is applied after the movement is completed. The first slide 9 is located at the tail end of the cross bar 6. The side slide groove 8 is provided to improve the sliding smoothness of the first slide 9 and the second slide 12. A first electric push rod 13 is provided between the second slide 12 and the cross plate 14. The lower end of the first electric push rod 13 is provided with a cross plate 14. The cross plate 14 is arranged parallel to the fixed seat 2. A bottom slide groove 19 is provided at the lower end of the cross plate 14. The lower end of the bottom slide groove 19 is slidably connected with a slider 15. A second electric push rod 18 is provided between the slider 15 and the bottom slide groove 19. A sleeve 16 is provided at the lower end of the slider 15. The marking pen 17 is sleeved in the sleeve 16 to facilitate the installation and disassembly of the marking pen 17. The fixed seat 2 A control switch 20 is provided on the upper surface, and the input end of the control switch 20 is electrically connected to the output end of the external power supply, and the output end of the control switch 20 is electrically connected to the input ends of the first electric push rod 13 and the second electric push rod 18 respectively. By providing the first electric push rod 13 and the second electric push rod 18, it is convenient to control the lateral movement and longitudinal movement of the marking pen 17, thereby improving the convenience of use. The marking tooling for aluminum tube processing has a compact structure, a reasonable design, and is easy to operate. It can effectively improve the marking efficiency and accuracy before aluminum tube processing, greatly reduce the rework rate and scrap rate, and save production costs.

[0021] During use: five aluminum tubes are passed through the tube insertion port 3, and the two ends of the aluminum tubes are adjusted to be symmetrical relative to the fixed seat according to the scale 7. The second slide seat 12 is slid to move according to the marking position of the aluminum tube, and the position of the marking pen is adjusted according to the scale 7. Then, the first electric push rod 13 is controlled to start by the control switch 20. The first electric push rod 13 is extended so that the marking pen 17 contacts the surface of the aluminum tube, and then the second electric push rod 18 is controlled to move back and forth. The marking pen 17 draws a line on the surface of the aluminum tube. After marking one end of the aluminum tube, manual force is applied to control the cross bar 6 to rotate 180°, and then the second electric push rod 18 is controlled to move back and forth to mark the other end of the aluminum tube.
