An automatic feeding device for expanding the holes of air conditioning aluminum tubes Technical Field

[0001] This utility model relates to the field of air conditioner aluminum tube processing technology, specifically an automatic feeding device for expanding the hole of air conditioner aluminum tubes. Background Technology

[0002] With the continuous improvement of people's living standards, air conditioners have become an indispensable electrical appliance in modern homes and offices, and the market demand for air conditioners continues to grow. In the manufacturing process of air conditioners, aluminum tubes, as an important component of the refrigeration system, have their processing quality directly affecting the cooling performance and service life of the air conditioner. Hole enlargement of aluminum tubes is one of the key processes in the processing of air conditioner aluminum tubes. Hole enlargement allows the aluminum tubes to be tightly connected to other components (such as joints and valves), ensuring the sealing and stability of the refrigeration system and preventing refrigerant leakage.

[0003] For example, Chinese utility model patent application number 201822187282.7 discloses an automatic feeding device for a new type of air conditioning pipe bending machine, which can realize automatic continuous feeding, avoid the accumulation of multiple copper pipes, and is simple to operate and highly practical. However, the device still has certain defects;

[0004] When feeding air conditioning pipes, manual labor is required to place the pipes from the material platform onto the conveyor belt for transport, which increases labor costs and the probability of accidents.

[0005] Therefore, we propose an automatic feeding device for expanding the holes of air conditioning aluminum tubes to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide an automatic feeding device for expanding the hole of air conditioning aluminum tubes, so as to solve the problem mentioned in the background art that the current market requires manual placement of air conditioning tubes from the material table to the conveyor belt for transportation, which increases labor costs and the probability of accidents.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for expanding the hole of an air conditioning aluminum tube, comprising a workbench and a receiving assembly, wherein an mounting plate is installed on the right side of the upper surface of the workbench, an inclined block is installed on the upper surface of the workbench, and limit plates are installed on both the front and rear sides of the inclined block, and limit grooves are provided on the limit plates, and a movable plate is installed on the left side of the mounting plate via a first hydraulic rod;

[0008] The lower left side surface of the movable plate is provided with a sloping groove and a recess, and a connecting rod passes through the interior of the recess. A rotating block is sleeved on the connecting rod, and a receiving component is installed below the rotating block. The receiving component is connected to the sloping groove by a telescopic spring.

[0009] A storage box is installed above the workbench via a fixing strip;

[0010] The upper surface of the workbench is equipped with a hole-expanding clamp and a connecting frame, and a push block is installed on the side of the connecting frame near the receiving component via a second hydraulic rod.

[0011] Preferably, the movable plate is located above the inclined block, the movable plate abuts against the inclined block, and the movable plate is slidably connected to the limiting plate.

[0012] The above structural design ensures that the movable plate remains stable during movement, thereby guaranteeing that the receiving component can accurately move to the receiving and feeding position, improving the stability and reliability of the feeding process, and helping to achieve precise feeding.

[0013] Preferably, limit blocks are installed on both the front and rear sides of the movable plate, and the limit blocks pass through the limit grooves on the limit plate, with the limit blocks and limit grooves being slidably connected.

[0014] The above structural design can precisely limit the movement path of the movable plate, thereby accurately controlling the position of the receiving component.

[0015] Preferably, the groove is located above the inclined groove, the connecting rod is fixedly connected to the movable plate, the rotating block is rotatably connected to the connecting rod, and the receiving assembly is rotatably connected to the movable plate.

[0016] By adopting the above structural design, the automatic material receiving action of the receiving component is realized by the inclined plane block during the movement of the movable plate. The ingenious structural design simplifies the material receiving process and improves the automation and efficiency of material receiving.

[0017] Preferably, the left side of the receiving component has an arc-shaped structure design, and the right side of the receiving component is provided with an arc-shaped block. When the receiving component moves to the right, the arc-shaped block on its right side abuts against the inclined surface of the inclined block, and the elastic force of the telescopic spring is greater than the weight of the air conditioner aluminum pipe.

[0018] The above structural design facilitates material receiving and feeding, better adapts to the shape of the aluminum tube, and prevents the aluminum tube from slipping during transportation. On the other hand, the telescopic spring ensures the stability of the receiving assembly during material receiving and feeding, ensuring that the aluminum tube can be smoothly pushed to the hole-expanding clamp, thus achieving continuous automatic feeding.

[0019] Preferably, the storage box has openings on both the top and bottom sides, and the lower surface of the storage box abuts against the movable plate.

[0020] The above structural design integrates material storage and feeding. The storage box can store a certain number of aluminum tubes, ensuring the continuity of the feeding process, reducing the trouble of frequent feeding, improving overall production efficiency, and facilitating the placement and retrieval of aluminum tubes.

[0021] Preferably, the hole enlarging clamp is located on the rear side of the receiving assembly, and the center line of the arc-shaped structure on the left side of the receiving assembly coincides with the center line of the push block.

[0022] The above structural design enables the pusher to accurately push the aluminum tube on the receiving assembly into the reaming holder, ensuring precise positioning of the aluminum tube before reaming, improving the accuracy and stability of the reaming process, and thus enhancing the processing quality of the aluminum tube reaming.

Limiting plates 3 are installed on both the front and rear sides of the inclined block 2, and limiting grooves 4 are opened on the limiting plates 3.

Plate 7, movable plate 7 is located above inclined block 2, movable plate 7 abuts against inclined block 2, movable plate 7 is slidably connected to limiting plate 3, the first hydraulic rod 6 is activated, the first hydraulic rod 6 pushes movable plate 7 to move to the left along the limiting groove 4 on the limiting plate 3, the limiting blocks 8 on the front and rear sides of movable plate 7 slide in the limiting groove 4 to ensure the smooth movement of movable plate 7, limiting blocks 8 are installed on the front and rear sides of movable plate 7, and the limiting blocks 8 pass through the limiting groove 4 on the limiting plate 3, the limiting blocks 8 are slidably connected to the limiting groove 4, the limiting groove 4 facilitates the left and right movement of the limiting blocks 8, thereby limiting the movable plate 7 on the limiting block 8 and the receiving component 13 connected to the movable plate 7, so that the receiving component 13 can move accurately to the receiving position and the feeding position.

[0036] The lower left surface of the movable plate 7 is provided with a sloping groove 9 and a recess 10. The recess 10 is located above the sloping groove 9. The connecting rod 11 is fixedly connected to the movable plate 7, the rotating block 12 is rotatably connected to the connecting rod 11, and the receiving assembly 13 is rotatably connected to the movable plate 7. After the air conditioner aluminum tube is fed, the first hydraulic rod 6 is activated to move the movable plate 7 to the right. The first hydraulic rod 6 pushes the movable plate 7 to move the receiving assembly 13 to the right. When the arc-shaped block on the right side of the receiving assembly 13 abuts against the sloping surface of the sloping block 2, the receiving assembly 13 rotates counterclockwise along the connecting rod 11 under the action of the sloping surface. The arc-shaped structure on its left side gradually descends. At this time, the receiving assembly 13 just catches the aluminum tube falling from the storage box 16, realizing the receiving. The connecting rod 11 passes through the inside of the recess 10. The rotating block 12 is sleeved on the connecting rod 11, and the rotating block 12 is installed below the rotating block 12. There is a receiving component 13. The left side of the receiving component 13 has an arc-shaped structure design, and the right side of the receiving component 13 has an arc-shaped block. When the receiving component 13 moves to the right, the arc-shaped block on its right side abuts against the inclined surface of the inclined block 2. The elastic force of the telescopic spring 14 is greater than the weight of the air conditioner aluminum tube. The movable plate 7 drives the receiving component 13 to move to the left, so that the limiting block 8 on the movable plate 7 abuts against the left side of the limiting groove 4. At this time, the receiving component 13 corresponds to the hole expander clamp 17 and the push block 20. Then, the second hydraulic rod 19 is activated. The second hydraulic rod 19 drives the push block 20 to push the air conditioner aluminum tube on the receiving component 13 to the hole expander clamp 17 for fixation. Then, the hole expander is used to expand the hole of the air conditioner aluminum tube. This cycle is repeated to realize the continuous automatic feeding of the air conditioner aluminum tube. The receiving component 13 and the inclined groove 9 are connected by the telescopic spring 14.

[0037] A storage box 16 is installed above the workbench 1 via a fixing strip 15.

A push block 20 is installed on the side of the connecting frame 18 near the receiving assembly 13 via a second hydraulic rod 19. The hole expander clamp 17 is located on the rear side of the receiving assembly 13. The center line of the arc-shaped structure on the left side of the receiving assembly 13 coincides with the center line of the push block 20.

[0039] The hole-expanding clamp 17 and hole expander in this application are commonly used technical means in the field of aluminum tube hole expansion, and their structural principles will not be described in detail here.

[0040] Working principle: When using the automatic feeding device for expanding the hole of air conditioning aluminum tubes, firstly, the first hydraulic rod 6 is activated. The first hydraulic rod 6 pushes the movable plate 7 to move to the left along the limiting groove 4 on the limiting plate 3. The limiting blocks 8 on the front and rear sides of the movable plate 7 slide in the limiting groove 4 to ensure the smooth movement of the movable plate 7. The movable plate 7 drives the receiving component 13 to move to the left, so that the limiting block 8 on the movable plate 7 abuts against the left side of the limiting groove 4. At this time, the receiving component 13 corresponds to the expanding clamp 17 and the push block 20. Then, the second hydraulic rod 19 is activated. The second hydraulic rod 19 drives the push block 20 to push the air conditioning aluminum tube on the receiving component 13 to the expanding clamp 17 for fixation. Then, the expanding device is used to expand the hole of the air conditioning aluminum tube. By repeating this operation, the continuous automatic feeding of air conditioning aluminum tubes can be achieved.

[0041] After the aluminum tube for air conditioning is loaded, the first hydraulic rod 6 is activated to move the movable plate 7 to the right. The first hydraulic rod 6 pushes the movable plate 7 to move the receiving assembly 13 to the right. When the arc-shaped block on the right side of the receiving assembly 13 abuts against the inclined surface of the inclined block 2, the receiving assembly 13 rotates counterclockwise along the connecting rod 11 under the action of the inclined surface. The arc-shaped structure on its left side gradually descends. At this time, the receiving assembly 13 catches the aluminum tube falling from the storage box 16, realizing the receiving of the tube. This reciprocating operation completes a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
