[0002] Air conditioning aluminum pipes refer to a type of pipe used in air conditioning systems to transport refrigerant. They are made of aluminum and are valued for their good thermal conductivity, corrosion resistance, light weight, and relatively low cost.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-5As shown in this embodiment, a four-station reaming machine for processing air conditioner aluminum tubes includes a worktable 1. Two material feeding boxes 10 are fixedly connected to both sides of the worktable 1. Feeding blocks 12 are slidably connected between the inner walls of the four material feeding boxes 10. A sliding groove 24 is provided on the inner side of the worktable 1. Two displacement plates 20 are slidably connected between the inner walls of the sliding groove 24. A vertical plate 21 is fixedly connected to the top of each of the two displacement plates 20. Two reaming cutters 23 are rotatably connected to one side of each of the two vertical plates 21. A first support column 4 and a second support column 7 are fixedly connected to the top of the worktable 1. A connecting plate 13 is slidably connected between the first support column 4 and the second support column 7. A lifting assembly is provided between the first support column 4 and the second support column 7 to move the connecting plate 13. Four fixing blocks 27 are slidably connected to the bottom of the connecting plate 13. An adjusting assembly is provided on the top of the connecting plate 13 to move the four fixing blocks 27. A clamp is slidably connected to one side of each of the four fixing blocks 27. Block 28, a waste bin 2 is fixedly connected to the bottom of the workbench 1. A collection trough 34 is opened on one side of the waste bin 2. The collection trough 34 is connected to the interior of the waste bin 2. A collection frame 3 is slidably connected between the inner walls of the collection trough 34. A feeding telescopic electric cylinder 11 is fixedly installed at the bottom of each of the four feeding bins 10. The output ends of the four feeding telescopic electric cylinders 11 extend into the interior of the four feeding bins 10 and are fixedly connected to the four feeding blocks 12. A displacement telescopic electric cylinder 19 is fixedly installed on both sides of the workbench 1. The output ends of the two displacement telescopic electric cylinders 19 extend into the interior of the workbench 1 and are fixedly connected to the two displacement plates 20 respectively. Two drive motors 22 are fixedly installed on one side of each of the two upright plates 21. The output ends of the four drive motors 22 pass through the two upright plates 21 and are fixedly connected to the four reaming cutters 23 respectively. A cylinder 29 is fixedly installed on one side of each of the four fixed blocks 27. The output ends of the four cylinders 29 pass through the four fixed blocks 27 and are fixedly connected to the four clamping blocks 28 respectively.

[0025] When expanding the holes of aluminum tubes on a four-station reamer, the reamer is first connected to an external power source. Then, the controller activates four feeding telescopic cylinders 11. These cylinders push four feeding blocks 12 between the inner walls of four discharge boxes 10, lifting the four aluminum tubes and aligning them with the four reamer blades 23. Next, the lifting assembly moves the connecting plate 13 between the first support column 4 and the second support column 7. Four cylinders 29 then push four clamping blocks 28 to move on one side of four fixing blocks 27, thus securing the four aluminum tubes. At the same time, the adjusting component drives the four fixed blocks 27 to move at the bottom of the connecting plate 13, thereby aligning the openings of the four aluminum tubes with the four reaming cutters 23 respectively. Then, the two displacement telescopic electric cylinders 19 push the two displacement plates 20 to move between the inner walls of the slide 24. Meanwhile, the four drive motors 22 drive the four reaming cutters 23 to rotate on one side of the two vertical plates 21 respectively, thereby reaming the four aluminum tubes according to the reaming requirements. The debris after reaming passes through the inside of the workbench 1 and falls into the inside of the waste bin 2, and is finally recycled through the collection frame 3 inside the collection tank 34.

[0026] After the four aluminum tubes have completed the reaming process, the four cylinders 29 push the four clamping blocks 28 to move again, thereby releasing the four aluminum tubes from their fixation and facilitating the collection of the reamed aluminum tubes, thus improving the efficiency of the four-station reaming machine.

[0027] like Figures 1-5 As shown, the lifting assembly includes a lifting groove 5 and a guide groove 8. The lifting groove 5 and the guide groove 8 are respectively opened on one side of the first pillar 4 and the second pillar 7. The lifting groove 5 and the guide groove 8 pass through the first pillar 4 and the second pillar 7 respectively. A threaded rod 6 is rotatably connected between the inner walls of the lifting groove 5. A lifting block 31 is threadedly connected to the outer side of the threaded rod 6. One side of the lifting block 31 is fixedly connected to the connecting plate 13. A guide rod 9 is fixedly connected between the inner walls of the guide groove 8. A guide block 32 is slidably connected to the outer side of the guide rod 9. One side of the guide block 32 is fixedly connected to the connecting plate 13. A lifting motor 25 is fixedly installed on the top of the first pillar 4. The output end of the lifting motor 25 extends into the interior of the lifting groove 5 and is fixedly connected to the threaded rod 6.

[0028] The threaded rod 6 is driven by the lifting motor 25 to rotate between the inner walls of the lifting groove 5. At the same time, the guide block 32 is guided by the guide rod 9 inside the guide groove 8, so that the lifting block 31 and the guide block 32 drive the connecting plate 13 to move between the first support 4 and the second support 7, thereby improving the efficiency of the four-station reaming machine.

[0029] like Figures 1-5As shown, the adjustment assembly includes a first adjustment groove 14 and a second adjustment groove 16. Both the first adjustment groove 14 and the second adjustment groove 16 are located on the top of the connecting plate 13 and penetrate the connecting plate 13. A first bidirectional lead screw 15 and a second bidirectional lead screw 17 are rotatably connected between the inner walls of the first adjustment groove 14 and the second adjustment groove 16, respectively. Two adjustment blocks 30 are threadedly connected to the outer sides of the first bidirectional lead screw 15 and the second bidirectional lead screw 17, respectively. The bottoms of the four adjustment blocks 30 are fixedly connected to four fixed blocks 27, respectively. One end of the first bidirectional lead screw 15 and the second bidirectional lead screw 17 extends to the outer side of the connecting plate 13 and is fixedly connected to a pulley 33. A transmission belt 18 is rotatably connected to the outer side of the two pulleys 33. An adjustment motor 26 is fixedly installed on one side of the connecting plate 13. The output end of the adjustment motor 26 extends into the interior of the first adjustment groove 14 and is fixedly connected to the first bidirectional lead screw 15.

[0030] By adjusting the motor 26 to drive the first bidirectional lead screw 15 to rotate between the inner walls of the first adjusting groove 14, and then through the transmission cooperation between the transmission belt 18 and the two pulleys 33, the second bidirectional lead screw 17 is simultaneously driven to rotate between the inner walls of the second adjusting groove 16, thereby driving the four adjusting blocks 30 to drive the four fixed blocks 27 to move at the bottom of the connecting plate 13, thereby improving the processing quality of the four-station reaming machine.

[0031] This utility model provides a four-station reaming machine for processing aluminum tubes for air conditioners. The specific working principle is as follows: When reaming aluminum tubes with the four-station reaming machine, first, the reaming machine is connected to an external power source. Then, the controller activates four feeding telescopic cylinders 11. These cylinders push four feeding blocks 12 between the inner walls of four feeding boxes 10, thereby lifting the four aluminum tubes and aligning them with the four reaming cutters 23. Next, the lifting motor 25 drives the threaded rod 6 to rotate between the inner walls of the lifting groove 5. Simultaneously, the guide rod 9 inside the guide groove 8 guides the guide block 32, causing the lifting block 31 and guide block 32 to move the connecting plate 13 between the first support column 4 and the second support column 7. Then, four cylinders 29 push four clamping blocks 28 to move on one side of four fixing blocks 27, thus fixing the four aluminum tubes. Meanwhile, the first bidirectional lead screw 15 is driven to rotate between the inner walls of the first adjusting groove 14 by the adjusting motor 26. Then, through the transmission cooperation between the transmission belt 18 and the two pulleys 33, the second bidirectional lead screw 17 is driven to rotate between the inner walls of the second adjusting groove 16. This causes the four adjusting blocks 30 to drive the four fixed blocks 27 to move at the bottom of the connecting plate 13, thereby aligning the openings of the four aluminum tubes with the four reaming cutters 23. Subsequently, the two displacement telescopic electric cylinders 19 push the two displacement plates 20 to move between the inner walls of the slide groove 24. At the same time, the four transmission motors 22 drive the four reaming cutters 23 to rotate on one side of the two vertical plates 21, thereby reaming the four aluminum tubes according to the reaming requirements. The debris after reaming passes through the inside of the workbench 1 and falls into the inside of the waste bin 2. Finally, it is recycled and processed by the collection frame 3 inside the collection groove 34.

[0032] After the four aluminum tubes have completed the reaming process, the four cylinders 29 push the four clamping blocks 28 to move again, thereby releasing the four aluminum tubes from the fixation and making it easier to collect the reamed aluminum tubes. This completes the use of the four-station reaming machine.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
