[0030] refer to Figures 1 to 7 A grooving device for aluminum tubes includes a base platform 1 and a processing table 2. The processing table 2 is installed on the base platform 1, and the aluminum tube is placed on the processing table 2. A booster and a grooving assembly are also provided on the processing table 2. The booster pushes the aluminum tube toward the grooving assembly. At this time, the aluminum tube moves along the length of the processing table. When the aluminum tube comes into contact with the grooving assembly, the pusher continues to push the aluminum tube. The aluminum tube rotates during the movement. At this time, the grooving assembly forms a spiral groove on the outer surface of the aluminum tube.

[0031] The booster includes a push shaft 3, which is placed horizontally. A blind hole extending horizontally towards the slotting assembly is provided on the right side of the machining table 2. The push shaft 3 is threaded, and a push rod 3 is screwed into the blind hole, allowing the push shaft 3 to move along the length of the machining table 2. An extension plate 25 is connected to the push shaft 3, and a flat push plate 4 is fixedly connected above the extension plate 25. A through hole is provided in the center of the extension plate 25, through which the push shaft 3 passes. A washer 26 is provided between the extension plate 25 and the push shaft 3, and the washer 26 is fixedly connected to the push shaft 3. The 26 has outer edges at both ends, which are located on both sides of the extension plate 25. The diameter of the outer edge is larger than the diameter of the through hole on the extension plate 25, so that the washer 26 can rotate in the through hole. The washer 26 can make the extension plate 25 move simultaneously with the push shaft 3. The flat push plate 4 is located above the push shaft 3 and parallel to the push shaft 3. The end of the push shaft 3 is provided with a handle 24 that is fixedly connected. When the push shaft 3 rotates, it can drive the flat push plate 4 to move closer to the slotting assembly or further away from the slotting assembly. At this time, the flat push plate 4 applies a horizontal thrust to the aluminum tube.

[0032] The grooving assembly includes a support arm 5 fixed to the left side of the processing table 2. A positioning shaft 6 is fixed to the end of the support arm 5, with an angle of 100-115° between the positioning shaft 6 and the support arm 5. The support arm 5 is horizontal, while the positioning shaft 6 is inclined. A support arm 23 is located below the support arm 5 to keep it horizontal. A bushing 7 is mounted on the positioning shaft 6, rotating around the central axis of the positioning shaft 6. A positioning arm 8 is fixed on the bushing 7. Rotation of the bushing 7 causes the positioning arm 8 to rotate. When the positioning arm 8 is directly above the support arm 5, it is parallel to the support arm 5. At this point, an aluminum tube can be pushed onto the positioning arm 8 using a pusher. Due to the angle between the positioning shaft 6 and the support arm 5, rotating the bushing 7 causes the positioning arm 8 to rotate with the bushing 7, changing from a horizontal to a downward-inclined position, facilitating the removal of the aluminum tube from the positioning arm 8 by the worker.

[0033] A spiral groove 9 is provided on the positioning arm 8, and a guide disk 10 is connected through the spiral groove 9. The guide disk 10 is provided with a central hole, through which the positioning arm 8 passes. A protrusion is provided at the central hole of the guide disk 10, which is located inside the spiral groove 10, allowing the guide disk 10 to move along the spiral groove 9. When the guide disk 10 is subjected to a thrust, the guide disk 10 can move along the length direction of the positioning arm 8 toward the positioning shaft 6. Due to the spiral groove 9, the guide disk 10 will rotate during the movement.

[0034] To ensure the aluminum tube rotates simultaneously with the guide plate 10 during processing, a spiral groove is machined on the surface of the aluminum tube. When the end of the aluminum tube contacts the guide plate 10, the guide plate 10 can lock and position the end of the aluminum tube. For this purpose, a fixed sleeve 16 and an annular groove 11 are provided on the guide plate 10. The diameter of the annular groove 11 is smaller than the diameter of the fixed sleeve 16. The annular groove 11 and the fixed sleeve 16 are coaxially arranged with the center hole. An inner support sleeve 12 is screwed through the annular groove 11. The end of the aluminum tube extends into the fixed sleeve 16 and is simultaneously fitted onto the inner support sleeve 12. The fixed sleeve 16 is provided with a radially extending threaded through hole. A locking rod 13 is provided in the through hole. A pad is provided at the lower end of the locking rod 13. When the locking rod 13 is screwed, it can lock the end of the aluminum tube, so that the aluminum tube and the guide plate 10 rotate together.

[0035] The grooving assembly also includes a grooving cutter located at the right end of the support arm 5. The cutter includes a cutter head 14 and a cutter body 18. The cutter head 14 is located at the upper end of the cutter body 18. The right end of the support arm 5 has a radially extending through hole, and the cutter body 18 is located inside the through hole. The cutter body 18 can slide up and down inside the through hole. The cutting edge of the cutter head 14 is located above the support arm 5. A connecting assembly is fixedly connected below the cutter body 18. The connecting assembly includes a connecting rod 19 and a connecting block 20. The diameter of the connecting block 20 is larger than the through hole on the support arm 5, which can limit the movement of the cutter body 18. A lead screw 21 is located below the connecting block 20. A support plate 22 is located below the cutter body 18. The right end of the support plate 22 is fixedly connected to the processing table 2. A fixing rod is provided between the support plate 22 and the support arm 5. The support plate 22 has a threaded hole, and the lead screw 21 passes through the threaded hole. By rotating the lead screw 21, the cutter body 18 can be moved up and down, thereby adjusting the distance between the cutting edge of the cutter head 14 and the surface of the aluminum tube.

[0036] To prevent deformation of the aluminum tube due to stress at the grooving position during the grooving process, an internal support component is provided above the grooving cutter at the tail end of the positioning arm 8. This component can provide internal support for the inner wall of the aluminum tube at the grooving position. The internal support component includes a spring and an arc-shaped support plate 15. The spring is fixedly connected between the positioning arm 8 and the arc-shaped support plate 15. During installation, the aluminum tube is fitted onto the positioning arm 8. When the spring is compressed, it will generate a restoring force, causing the arc-shaped support plate 15 to contact the inner wall of the aluminum tube, thereby preventing deformation of the aluminum tube.

[0037] Depending on the processing requirements, different positioning arms 8 of the spiral groove 9 can be replaced to process spiral grooves with different spacings on the surface of the aluminum tube.

[0038] During processing, the flat push plate 4 provides a pushing force to the aluminum tube towards the slotting assembly, and the guide plate 10 provides resistance to the aluminum tube towards the flat push plate 4. Therefore, to prevent the aluminum tube from bending under force, a protective cover 17 is provided on the processing table 2. The protective cover 17 can cover the aluminum tube, thereby preventing the aluminum tube from being bent. One side of the protective cover 17 is hinged to the processing table 2 and can be flipped on the processing table 2. A limiting rail 27 is provided inside the protective cover 17. When the protective cover 17 is above the aluminum tube, the aluminum tube is located inside the limiting rail 27, which can prevent the aluminum tube from bending to both sides. The flat push plate 4 can pass through the limiting rail 27 to push the aluminum tube.

[0039] During operation, the worker first passes the end of the aluminum tube through the inner support component on the positioning arm 8, then rotates the bushing 7 to align the positioning arm 8 with the support arm 5. The aluminum tube is then fixed to the guide plate 10 by the locking rod 13. The protective cover 17 is flipped over to position the aluminum tube within the limiting track 27. The lead screw 21 is rotated to adjust the position of the grooving cutter so that the blade contacts the surface of the aluminum tube. The push shaft 3 is rotated to push the flat push plate 4 towards the grooving cutter. The guide plate 10 rotates along the spiral groove 9, and the aluminum tube rotates together with the guide plate 10. The cutter head 14 processes a spiral groove on the surface of the aluminum tube. After processing, the protective cover 17 is opened, the locking rod 13 is released, the bushing 7 is rotated to tilt the positioning arm 8 downwards for easy disassembly, and the push rod 3 is rotated to return the flat push plate 4 to its original position.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this invention. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
