[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] like Figure 1-5 As shown, an automatic aluminum tube punching machine includes a punching rod 51 and a first drive cylinder 52 for driving the punching rod 51 to move axially. It also includes a base 1 on which a fixed seat 2 and a drive seat 41 slidably arranged relative to the fixed seat 2 are provided. A pressure plate 42 for clamping the tube is slidably arranged on the drive seat 41. A clamping seat 3 is slidably arranged on the fixed seat 2. The fixed seat 2 and the clamping seat 3 are respectively provided with a through hole 22 and a through groove 32. The clamping seat 3 is driven to slide close to the fixed seat 2 to clamp the tube. The through groove 32 is coaxially aligned with the through hole 22 to expose the tube. The through groove 32 and the through hole 22 are aligned with the punching rod 51 arranged on the base 1.

[0027] Specifically, such as Figure 1 As shown, the fixed seat 2 is disposed on the base 1, while the drive seat 41 is slidably disposed in the horizontal groove 11 of the base 1. The clamping seat 3 is vertically slidably disposed in the fixed seat 2 and in the vertical groove 12 opened on the base 1. A second drive cylinder 91 for driving the clamping seat 3 to slide closer relative to the fixed seat 2 is also disposed in the vertical groove 12. A first drive cylinder 52 for driving the punching rod 51 to move axially is also disposed on the base 1. The pressure plate 42 can be used to press the drive seat 41 to clamp and fix one end of the aluminum tube fitting, while the other end of the aluminum tube fitting passes between the fixed seat 2 and the clamping seat 3. Then the second drive cylinder 91 can be used to... The clamping seat 3 slides closer to the fixed seat 2 to clamp and fix the other end of the aluminum tube fitting, thus completing the overall fixation of the fitting. At this time, the slot 32 and the through hole 22 are coaxially aligned to expose the fitting. The first drive cylinder 52 drives the punching rod 51 to enter along the slot 32 and the through hole 22 to perform punching operations on the aluminum tube fitting. Subsequently, the second drive cylinder 91 drives the clamping seat 3 to slide away from the fixed seat 2 to release one end of the fitting. The drive seat 41 slides horizontally to drive the fitting to move horizontally relative to the fixed seat 2, and the clamping seat 3 and the fixed seat 2 can fix the end of the fitting again to perform punching operations at different positions on the aluminum tube. Thus, by using the clamping seat 3, the fixed seat 2, the drive seat 41 and the pressure plate 42, multiple automated punching operations can be performed on a single aluminum tube. During the punching operation, repeated manual clamping is not required, thereby improving the efficiency of the punching operation.

[0028] Among them, the first drive cylinder 52 and the second drive cylinder 91 can be hydraulic cylinders.

[0029] In the above technical solution, clamping seat 3, fixing seat 2, driving seat 41 and pressure plate 42 are used to realize automated multi-quantity punching operations for a single aluminum tube. In the punching operation, there is no need for manual repeated clamping, thereby improving the efficiency of punching operation.

[0030] As a further embodiment provided in this utility model, a rotating roller 6 is rotatably disposed on the clamping seat 3 on the vertically lower side of the pipe, and the rotating roller 6 is located on the side of the clamping seat 3 opposite to the drive seat 41.

[0031] Specifically, such as Figure 3As shown, the rotating roller 6 is rotatably mounted on the side of the clamping seat 3 facing away from the drive seat 41. At this time, if the drive seat 41 and the pressure plate 42 clamp the right end of the aluminum tube, and the clamping seat 3 is away from the fixed seat 2 and does not limit the clamping of the left end of the aluminum tube, the drive seat 41 can slide horizontally to the left to drive the aluminum tube to move. However, due to the long axial length of the aluminum tube, the left end of the aluminum tube is easily bent under the influence of gravity and abuts against the rotating roller 6. The rotating roller 6 is used to support the downward tilting end of the aluminum tube, and the rotating roller 6 rotates synchronously with the horizontal movement of the aluminum tube, thereby avoiding the problem of scratching the surface of the aluminum tube by rubbing against the clamping seat 3 when the aluminum tube moves horizontally and changes position, thus improving the protection of the aluminum tube.

[0032] As a further embodiment provided in this utility model, flexible abutment rings 7 in the shape of buckets are symmetrically arranged on the rotating roller 6.

[0033] Specifically, such as Figure 5 As shown, flexible abutment rings 7 are symmetrically fixedly connected to the rotating roller 6. When the clamping seat 3 slides close to the fixed seat 2 to clamp and limit the aluminum tube, the rotating roller 6 slides synchronously with the clamping seat 3 to the fixed seat 2, thereby causing the flexible abutment rings 7 to deform and adhere to the vertically lower side of the aluminum tube, thus further reducing the vibration of the aluminum tube during the clamping and punching process and improving the quality of the formed hole. When the clamping seat 3 slides away from the fixed seat 2 to release the aluminum tube, the flexible abutment rings 7 undergo their own elastic deformation to support the lower part of the aluminum tube, thereby reducing the scratching problem on the surface of the aluminum tube caused by the rolling contact between the aluminum tube and the rotating roller 6, and further improving the protection of the aluminum tube.

[0034] As a further embodiment provided in this utility model, a sliding plate 8 and an elastic element 92 are symmetrically arranged on the clamping seat 3. The sliding plate 8 is arranged vertically and the elastic element 92 drives the sliding plate 8 to slide away from the clamping seat 3 so as to support the pipe vertically downward.

[0035] Specifically, such as Figure 5 As shown, the slide plate 8 is provided with an arc-shaped contact surface 81, and the second sliding part 83 of the slide plate 8 is slidably disposed in the second sliding groove 34 opened on the clamping seat 3. The elastic member 92 is disposed in the second sliding groove 34 to drive the slide plate 8 to slide away from the clamping seat 3. When the clamping seat 3 slides close to the fixing seat 2 to clamp and fix the aluminum tube, the second elastic member 92 drives the slide plate 8 to slide close to the aluminum tube, and the contact surface 81 of the slide plate 8 abuts against the bottom of the aluminum tube to further improve the fixing stability of the aluminum tube.

[0036] The elastic element 92 can be replaced by any elastic object known to those skilled in the art, such as a spring, an airbag, or an elastic plate.

[0037] As a further embodiment of this utility model, the slide plate 8 is provided with protrusions 82 arranged in a circumferential array, and the roller 6 is provided with abutment grooves 61 arranged in a circumferential array. The roller 6 is driven to rotate so that the protrusions 82 successively disengage and are embedded in a plurality of abutment grooves 61.

[0038] Specifically, such as Figure 5 As shown, the slide plate 8 has a circumferential array of protrusions 82, and the roller 6 has a circumferential array of contact grooves 61. When the drive seat 41 and the pressure plate 42 clamp the right end of the aluminum tube, and the clamping seat 3 is away from the fixed seat 2 and does not limit the left end of the aluminum tube, the drive seat 41 can slide horizontally to the left to drive the aluminum tube to move. The roller 6 rotates synchronously with the horizontal movement of the aluminum tube. While the roller 6 is rotating, the protrusions 82 first move away from one contact groove 61 and then move again to embed into another contact groove 61. Thus, the protrusions 82 contact several contact grooves 61 in sequence. At this time, the roller 6 drives the slide plate 8 to slide back and forth to radially strike the aluminum tube, thereby knocking off the debris or waste generated by punching on the aluminum tube, thus avoiding damage to the aluminum tube caused by the debris or waste being squeezed between the clamping seat 3 and the fixed seat 2.

[0039] As a further embodiment provided in this utility model, the clamping seat 3 is provided with a chip guide groove 33 facing away from the drive seat 41, and the rotating roller 6 is located in the chip guide groove 33.

[0040] Specifically, the clamping seat 3 has a chip guide groove 33 facing away from the drive seat 41. The rotating roller 6 is located in the chip guide groove 33. When the rotating roller 6 rotates, it drives the sliding plate 8 to slide back and forth to strike the aluminum tube radially, knocking off the chips or waste generated by punching on the aluminum tube. The chips or waste will fall along the chip guide groove 33 to the outside of the clamping seat 3, thus facilitating the discharge of chips or waste.

[0041] As a further embodiment of this utility model, the fixing seat 2 is provided with an upper abutment groove 21, and the clamping seat 3 is provided with a lower abutment groove 31. The clamping seat 3 is connected to the upper abutment groove 21 through a hole 22 and to the lower abutment groove 31 through a groove 32. The clamping seat 3 slides closer to the fixing seat 2 so that the lower abutment groove 31 and the upper abutment groove 21 clamp and fix the pipe fitting.

[0042] Specifically, such as Figure 5 As shown, it is connected to the lower abutment groove 31 through groove 32, as... Figure 2 As shown, the through hole 22 is connected to the upper abutment groove 21. When the clamping seat 3 slides closer to the fixed seat 2, the lower abutment groove 31 and the upper abutment groove 21 clamp the fixed pipe, and the through groove 32 moves to be coaxially aligned with the through hole 22.

[0043] As a further embodiment of this utility model, a first sliding part 35 is symmetrically arranged on the clamping seat 3, and the first sliding part 35 is slidably arranged in the first sliding groove 23 opened on the fixed seat 2.

[0044] Specifically, the first sliding part 35 of the clamping seat 3 is slidably arranged in the first sliding groove 23 opened on the fixed seat 2, thereby improving the vertical sliding stability of the clamping seat 3.

[0045] As a further embodiment of this utility model, it also includes a rotating rod 43 that is threadedly engaged with the drive seat 41. The rotating rod 43 is rotatably connected to the pressure plate 42. The drive seat 41 is provided with a fixed groove 411 and a third sliding groove 413. The pressure plate 42 is slidably disposed in the third sliding groove 413. The rotating rod 43 is driven to rotate so that the pressure plate 42 slides along the third sliding groove 413 relative to the fixed groove 411.

[0046] Specifically, such as Figure 4 As shown, the rotating rod 43 is threadedly engaged with the drive seat 41, and the rotating rod 43 can be manually driven to rotate. This causes the pressure plate 42 to slide along the third sliding groove 413 relative to the fixed groove 411, and the pressure plate 42 and the fixed groove 411 clamp and fix the aluminum tube relative to the drive seat 41, thus facilitating the actual clamping between the aluminum tube and the drive seat 41.

[0047] As a further embodiment of this utility model, the base 1 is provided with a threaded screw 44 and a drive motor 45. The threaded screw 44 is rotatably arranged and cooperates with the threaded hole 412 opened on the drive seat 41. The threaded screw 44 is fixedly connected to the output end of the drive motor 45.

[0048] Specifically, such as Figure 4 As shown, the threaded screw 44 is rotatably arranged on the base 1. The threaded screw 44 can be driven to rotate by the drive motor 45. The threaded screw 44 drives the drive seat 41 to slide horizontally relative to the fixed seat 2, thereby driving the aluminum tube to move horizontally and change the drilling position.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
