Description

Technical Field

[0001] The present invention relates to the technical field of flaring of two heat exchangers of air conditioners, and in particular, to a flaring mechanism. Background Art

[0002] In the traditional flaring process of two heat exchangers, usually when the entire flaring crossbeam descends to the position of the pipe orifices of the two heat exchangers, the pipe orifices of the two heat exchangers push the flaring cup up to a suitable position. Then, the servo motor drives through a synchronous belt to achieve horizontal movement. During the movement, the rising flaring cup is pressed down to the initial position. During this process, the end of the flaring cup expands the copper pipe, and the port of the copper pipe is formed into a flared shape to meet the requirements of the heat exchange tube expanding and flaring process for the insertion of small U-bend elbows process.

Detailed implementation mode

[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] Please refer to Figures 1 to 6 , the present invention provides a flaring mechanism, including: a support body 1, a flaring component 10 is arranged on the support body 1, and the flaring component 10 is arranged movably relative to the support body 1 in the vertical direction; a lifting assembly 2 is arranged on the support body 1, at least part of the lifting assembly 2 is opposite to the flaring component 10, and the lifting assembly 2 is arranged movably in the vertical direction, and the flaring component 10 is pushed into the target pipe fitting by the lifting assembly 2; a measuring assembly 3 is arranged on the support body 1 and connected to the lifting assembly 2, and the measuring assembly 3 is opposite to the flaring component 10, so as to measure the moving distance of the flaring component 10 in the vertical direction after the target pipe fitting pushes the flaring component 10 to move upward; wherein, the lifting assembly 2 is communicatively connected to the measuring assembly 3 to control the displacement of the flaring component 10 extending into the target pipe fitting according to the distance measured by the measuring assembly 3.

[0027] According to the flaring mechanism provided by the present invention, it includes a support body 1, a lifting assembly 2, and a measuring assembly 3. A flaring component 10 is arranged on the support body 1. The flaring component 10 is arranged to be vertically movable relative to the support body 1. The lifting assembly 2 is arranged on the support body 1. At least part of the lifting assembly 2 faces the flaring component 10. The lifting assembly 2 is arranged to be vertically movable. The flaring component 10 is pushed by the lifting assembly 2 to extend into the target pipe fitting. The measuring assembly 3 is arranged on the support body 1 and connected to the lifting assembly 2. The measuring assembly 3 faces the flaring component 10. After the target pipe fitting pushes the flaring component 10 to move upward, the vertical moving distance of the flaring component 10 is measured by the measuring assembly 3. Among them, the lifting assembly 2 is communicatively connected to the measuring assembly 3 to control the displacement of the flaring component 10 extending into the target pipe fitting according to the distance measured by the measuring assembly 3. In the flaring mechanism of the present invention, by arranging the measuring assembly 3 and communicatively connecting the measuring assembly 3 with the lifting assembly 2, after the target pipe fitting pushes the flaring component 10 to move correspondingly, since the materials and specifications of the target pipe fittings are different, therefore, the vertical moving distance of the flaring component 10 is first measured by the measuring assembly 3. After receiving the distance information, the lifting assembly 2 can accurately control the downward pushing distance of the flaring component 10 to ensure that the flaring depth of the target pipe fitting is consistent, so as to improve the accuracy and quality of flaring the target pipe fitting.

[0028] Taking the production of air conditioner heat exchangers as an example in the present invention, the flaring mechanism is used to flare the copper pipes on the air conditioner heat exchangers. Since the copper pipes need to be bent into a U shape before flaring, and the two pipe orifices of the copper pipe are flared simultaneously during flaring. During the bending process, the heights of the two pipe orifices of the copper pipe may be inconsistent. Therefore, when the copper pipe is aligned with the flaring component 10, the lifted height of each flaring component 10 is also different. At this time, since the initial distance between the measuring assembly 3 and the flaring component 10 is fixed after the flaring mechanism is assembled, the lifted height of the flaring component 10 can be directly measured by the measuring assembly 3. In this way, the control system of the flaring mechanism calculates the distance to obtain the actual downward moving distance of each flaring component 10, and then controls the lifting assembly 2 to push the flaring component 10 to move downward to extend into the pipe orifice for flaring treatment, which ensures that the flaring depth of each copper pipe is consistent and improves the production quality of the air conditioner heat exchangers in the subsequent processing.

[0029] Specifically, there are multiple flaring components 10, and the multiple flaring components 10 are sequentially arranged along the length direction of the support body 1; the flaring mechanism further includes: a mounting plate 4 arranged on the support body 1, the mounting plate 4 is movably arranged along the extending direction of the support body 1, and both the lifting assembly 2 and the measuring assembly 3 are mounted on the mounting plate 4. In this way, by using the mounting plate 4, the lifting assembly 2 and the measuring assembly 3 are integrated, enabling the lifting assembly 2 and the measuring assembly 3 to move simultaneously, achieving the purpose of changing the measurement and pushing the flaring component 10 to move, and improving the processing efficiency.

[0030] In the present invention, the measuring assembly 3 includes a laser displacement sensor, and the laser displacement sensor is connected to the lifting assembly 2; a light-transmitting hole is provided on the mounting plate 4, and the laser displacement sensor is opposite to the light-transmitting hole. The laser displacement sensor includes a laser emitting part 30 and a receiving part 31. The laser emitting part 30 emits laser to the top of the flaring component 10, and then it returns to the receiving part 31, thereby detecting the rising height of each flaring component 10 and recording the rising height of each flaring component 10 on the programmable logic controller system.

[0031] During the specific implementation process, as Figure 1 and Figure 3 shown, the flaring mechanism further includes: a horizontal driving component 5 arranged on the support body 1, at least part of the horizontal driving component 5 is movably arranged along the extending direction of the support body 1, and the mounting plate 4 is connected to the horizontal driving component 5; a sliding track 6 is arranged on the support body 1, the sliding track 6 extends along the extending direction of the support body 1, and the mounting plate 4 is connected to the sliding track 6. Specifically, the horizontal driving component 5 includes a slide bar 50, the slide bar 50 is fixed on the support body 1, the slide bar 50 is a threaded rod, the mounting plate 4 is threadedly connected to the slide bar 50 through a connecting block, and the slide bar 50 is driven to rotate by a motor. Using a lead screw structure, the structure is simpler. During the movement of the mounting plate 4, the lifting assembly 2 can simultaneously receive the distance information on the programmable logic controller system to push down the flaring component 10.

[0032] Among them, as Figure 2As shown in the figure, an avoidance space 11 is provided on the support body 1. A plurality of flaring members 10 are opposite to the avoidance space 11, and the avoidance space 11 extends along the extension direction of the support body 1. There are two groups of horizontal driving members 5, and the two groups of horizontal driving members 5 are respectively arranged on both sides of the avoidance space 11. The lifting assembly 2 drives the flaring members 10 to move through the avoidance space 11. Among them, a support beam is provided on the support body 1. The support beam is opposite to the avoidance space 11. Through holes are provided on the support beam. The flaring members 10 are inserted into the through holes. There are a plurality of through holes, and the plurality of through holes are arranged in one-to-one correspondence with the plurality of flaring members 10. The flaring member 10 includes a flaring body and a limiting block. The limiting block is arranged at the end of the flaring body. The flaring body is inserted into the through hole, and the limiting block contacts the main body of the through hole formed by the support beam to prevent the flaring body from falling out of the through hole in the vertical direction. The flaring body is in clearance fit with the through hole, so that the target pipe fitting can push the flaring member 10 upward. In a specific implementation, limiting blocks 7 are provided on the support body 1. There are two limiting blocks 7, and the two limiting blocks 7 are respectively arranged on both sides of the avoidance space 11 along the length direction of the support body 1. The mounting plate 4 is limited by the limiting blocks 7 to prevent the mounting plate 4 from being stuck with the sliding rod 50.

[0033] During the specific implementation process, as Figure 4 shown, the lifting assembly 2 includes: a flaring top block 20, which is movably arranged in the vertical direction. The flaring top block 20 is opposite to the flaring member 10, and the flaring top block 20 contacts and pushes the flaring member 10 to move. Among them, the flaring top block 20 has a first contact end face, and the flaring member 10 has a second contact end face. The area of the first contact end face is larger than the area of the second contact end face, so as to ensure that the force on the flaring member 10 is uniform during the downward push of the flaring top block 20.

[0034] Furthermore, in order to drive the flaring top block 20 to lift and lower, the lifting assembly 2 further includes: a connecting rod 21, which is rotatably arranged around its own axis; the flaring top block 20 is sleeved on the connecting rod 21, and the flaring top block 20 is threadedly connected with the connecting rod 21. Such a structure is simple and easy to implement.

[0035] In the embodiment provided by the present invention, the lifting assembly 2 further includes: a guide rod 23, which is arranged on the side of the connecting rod 21. The guide rod 23 extends in the vertical direction. A limiting channel is provided on the flaring top block 20, and the flaring top block 20 is sleeved on the guide rod 23 through the limiting channel. The guide rod 23 is in clearance fit with the limiting channel. In this way, during the lifting and lowering process of the flaring top block 20, the guide rod 23 is used to guide and limit the flaring top block 20 to prevent the flaring top block 20 from shifting during the lifting and lowering process.

[0036] The lifting assembly 2 further includes: a vertical driving member 24 having a driving shaft rotatable about its own axis, the driving shaft being connected to the connecting rod 21; and a support plate 25, where the vertical driving member 24 and the guide rod 23 are both disposed on the support plate 25. Such an arrangement facilitates the installation of the vertical driving member 24. Preferably, the support plate 25 is disposed at a relative interval with respect to the mounting plate 4, and the guide rod 23 passes through the mounting plate 4 and is connected to the support plate 25.

[0037] In the specific implementation process, in order to improve the processing efficiency, the measuring assembly 3 is one group or multiple groups. When the measuring assembly 3 is multiple groups, the multiple groups of measuring assemblies 3 are disposed at intervals along the extending direction of the support body 1; the lifting assembly 2 is one group or multiple groups. When the lifting assembly 2 is multiple groups, the multiple groups of lifting assemblies 2 are disposed in one-to-one correspondence with the multiple groups of measuring assemblies 3.

[0038] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0039] According to the flaring mechanism provided by the present invention, it includes a support body 1, a lifting assembly 2, and a measuring assembly 3. A flaring member 10 is disposed on the support body 1, and the flaring member 10 is disposed movably relative to the support body 1 in the vertical direction. The lifting assembly 2 is disposed on the support body 1, at least a part of the lifting assembly 2 is opposite to the flaring member 10, and the lifting assembly 2 is disposed movably in the vertical direction. The flaring member 10 is pushed by the lifting assembly 2 to extend into the target pipe fitting; the measuring assembly 3 is disposed on the support body 1 and connected to the lifting assembly 2, and the measuring assembly 3 is opposite to the flaring member 10, so as to measure the moving distance of the flaring member 10 in the vertical direction through the measuring assembly 3 after the target pipe fitting pushes the flaring member 10 to move upward; wherein, the lifting assembly 2 is communicatively connected to the measuring assembly 3 to control the displacement of the flaring member 10 extending into the target pipe fitting according to the distance measured by the measuring assembly 3. In the flaring mechanism of the present invention, by providing the measuring assembly 3 and communicatively connecting the measuring assembly 3 with the lifting assembly 2, after the target pipe fitting pushes the flaring member 10 to move, since the materials and specifications of the target pipe fittings are different, therefore, the measuring assembly 3 is used to first measure the moving distance of the flaring member 10 in the vertical direction. After the lifting assembly 2 receives the distance information, it can accurately control the distance that the flaring member 10 is pushed downward to ensure that the flaring depth of the target pipe fitting is consistent, so as to improve the accuracy and quality of the flaring of the target pipe fitting.
