Description

Technical Field

[0001] This utility model relates to the field of eye tube processing technology, and in particular to a continuous operation device for connecting tube flaring mouth clamping eye tube. Background Technology

[0002] An air conditioner consists of four main parts: a refrigeration (heating) cycle system, an air circulation and ventilation system, an electrical control system, and a housing. It is a small air conditioning unit that maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space. Among these components, the air conditioner filter is a very important part of the air conditioner.

[0003] Specifically, depending on the type and function of the air conditioner, there are various types of air conditioner filters. One type is the copper air conditioner filter, which consists of a small copper connecting pipe (referred to as the connecting pipe). To allow the connecting pipe to connect properly to other components of the air conditioner, one end of the connecting pipe needs to be machined into an eyelet shape. Simultaneously, the eyelet needs to be flared. Although existing processing equipment can complete the aforementioned process, it requires multiple different pieces of equipment in separate steps, making the process relatively complex and inefficient. Utility Model Content

[0004] In view of the technical problems of the prior art, this utility model provides a continuous operation device for connecting tube flare mouth clamping eye tube.

[0007] In practical applications, the end of the connecting tube to be processed is placed between two clamping blocks. Driving the two clamping blocks causes the extrusion plates to move closer together, thus extruding the end of the connecting tube and shaping it into an eyelet. Subsequently, a mandrel is driven, extending into the eyelet, causing the flared bevel to abut against the end of the eyelet, thereby completing the outward expansion of the eyelet end. In summary, this invention allows for the continuous processing of the eyelet and flared ends of the connecting tube without the need for other processing equipment. This effectively simplifies the processing steps and improves processing efficiency.

[0010] Furthermore, the transmission structure includes a power rod, a transmission rod, and a connecting rod; the power rod is connected to the output end of the clamping cylinder; one end of the transmission rod is oscillatingly connected to the power rod, and the other end is oscillatingly connected to the connecting rod; the connecting rod is oscillatingly connected to the clamping block; a swing shaft is provided on the connecting rod; the swing shaft is located between the transmission rod and the clamping block.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A continuous operation device for flaring and clamping eye tubes with connecting pipes includes: a clamping device 1, a flaring device 2, and an assembly frame 3. The assembly frame 3 is connected to the clamping device 1 and the flaring device 2. Specifically, the clamping device 1 includes clamping blocks 11, a clamping cylinder 12, a transmission structure 13, and limiting rods 14. The limiting rods 14 are fixedly mounted on the assembly frame 3. There are two limiting rods 14, which are arranged parallel to each other. There are two clamping blocks 11. The clamping blocks 11 are slidably sleeved on the limiting rods 14. The clamping blocks 11 are arranged opposite to each other. The clamping blocks 11 are provided with a pressing plate 111 and dotting protrusions 112. The dotting protrusions 112 are respectively provided on both sides of the pressing plate 111. The clamping cylinder 12 is fixedly mounted on the assembly frame 3. The transmission structure 13 includes a power rod 131, a transmission rod 132, and a connecting rod 133. The power rod 131 is connected to the output end of the clamping cylinder 12. Correspondingly, a support plate corresponding to the power rod 131 is provided on the assembly frame 3. The power rod 131 slidably passes through the support plate. There are two transmission rods 132, respectively located on both sides of the power rod 131. One end of each transmission rod 132 is oscillatingly connected to the power rod 131, and the other end is oscillatingly connected to the connecting rod 133. The connecting rod 133 is oscillatingly connected to the clamping block 11. That is, one clamping block 11 corresponds to one transmission rod 132 and one connecting rod 133. A swing shaft 1331 is also provided on the connecting rod 133. The swing shaft 1331 is fixedly connected to the assembly frame 3. The swing shaft 1331 is located between the transmission rod 132 and the clamping block 11.

[0020] The flaring device 2 includes a mandrel 21 and a flaring cylinder 22. There are two mandrels 21, positioned between clamping blocks 11. The two mandrels 21 are arranged vertically. The mandrels 21 are slidably connected to the assembly frame 3. One end of each mandrel 21 has a flaring bevel 211 surrounding it. A clearance groove 212 is also provided on the mandrel 21, located at the end of the mandrel 21 furthest from the flaring bevel 211. The clearance groove 212 corresponds to the dotting protrusion 112. The flaring cylinder 22 is positioned between two connecting rods 133 and is fixedly connected to the assembly frame 3. The output end of the flaring cylinder 22 is connected to the mandrel 21 to push it to extend or retract.

[0021] In the default state, the two clamping blocks 11 are separated from each other. The mandrel 21 is in a retracted state. When processing of the connecting tube is required, the end of the connecting tube to be processed is placed between the two clamping blocks 11. At this time, the clamping cylinder 12 is activated. The output end of the clamping cylinder 12 extends, thereby pushing the power rod 131 to extend. Driven by the power rod 131, the transmission rod 132 pushes the connecting rod 133 to swing about the swing shaft 1331. As a result, the end of the connecting rod 133 connected to the clamping block 11 pushes the clamping block 11 to slide along the limiting rod 14, thereby bringing the two clamping blocks 11 closer to each other. On the other hand, during the process of the connecting rod 133 pushing the clamping block 11, one end of the transmission rod 132 swings relative to the power rod 131, and the other end swings relative to the connecting rod 133. The end of the connecting rod 133 swings relative to the clamping block 11. In this way, the aforementioned process can be carried out normally.

[0022] When the clamping blocks 11 approach each other, the pressing plate 111 presses the end of the connecting tube, causing it to deform accordingly. When the two clamping blocks 11 move to the designated position, the end of the connecting tube is compressed into an eye tube. At the same time, the dotting protrusions 112 press against the outer wall of the eye tube, forming depressions on the outer wall of the eye tube corresponding to the dotting protrusions 112. Thus, the dotting of the eye tube is completed.

[0023] At this time, the flaring cylinder 22 is activated. Driven by the flaring cylinder 22, the mandrel 21 extends. Thus, the mandrel 21 extends into the eye tube. When the flaring bevel 211 on the mandrel 21 abuts against the end of the eye tube, the flaring bevel 211 squeezes the end of the eye tube, causing the end of the eye tube to deform accordingly, resulting in the end of the eye tube expanding outwards. This completes the flaring of the eye tube. Simultaneously, as the mandrel 21 flares the eye tube, the retaining groove 212 moves to a position corresponding to the marking protrusion 112. Therefore, through the retaining groove 212, during the extension of the mandrel 21, the mandrel 21 will not abut against the recessed points on the eye tube, thus affecting the marking of the marking protrusion 112.

[0024] Preferably, a feeding cylinder can also be provided, which is connected to the other end of the connecting pipe. Thus, when the output end of the feeding cylinder extends, it pushes the end of the connecting pipe to be processed into the space between the two clamping blocks 11. This allows the feeding cylinder to position the connecting pipe, thereby preventing uncontrollable tilting of the connecting pipe during processing.

[0025] In summary, this utility model can complete the processing of the eye tube, flaring, and dotting on the connecting tube in one go, without the need to change other equipment during the processing, thus effectively simplifying the processing steps and improving processing efficiency.
