[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] In the manufacturing process of refrigeration equipment such as air conditioners and refrigerators, the production of evaporators and condensers is one of the key links. Especially in the expansion process of U-shaped tubes, the receiving seat system of the traditional horizontal tube expander plays an important role. However, the existing horizontal tube expander receiving seat has the following technical problems and limitations:

[0045] In the prior art, traditional receiving seats usually use clamps to fix copper tubes. This method easily leaves scratches on the surface of the copper tube, which not only affects the appearance of the product, but also may reduce the service life of the pipeline fittings and increase the potential failure rate in subsequent use. At the same time, since it is difficult to accurately control the clamping force in the traditional clamping method, the copper tube may be deformed or not fixed firmly due to clamping too tightly or too loosely, affecting production efficiency and product quality.

[0046] The main purpose of the present invention is to provide a receiving seat and a tube expander having the same, so as to solve the problem in the prior art that the U-shaped tube is damaged and deformed during the receiving process.

[0047] In order to achieve the above object, according to one aspect of the present invention, a receiving seat is provided, comprising:

[0048] A fixing component 1, on which an adsorption structure 2 for generating negative pressure is provided;

[0049] The adsorption member 3 is arranged on the adsorption structure 2;

[0050] Among them, the adsorption part 3 includes at least two adsorption plates 301, and at least two adsorption plates 301 are provided with multiple adsorption ports 302 arranged along their extension direction. The multiple adsorption ports 302 are all connected with at least part of the adsorption structure so that when the adsorption structure 2 generates negative pressure, the workpiece can be adsorbed through the multiple adsorption ports 302.

[0051] Specifically, Figures 1 to 3 As shown, the receiving seat provided in the present application includes a fixing component 1, on which an adsorption structure 2 is provided, the adsorption structure 2 can generate negative pressure, and an adsorption member 3 is provided on the adsorption structure 2, and the adsorption member 3 includes at least two adsorption plates 301 arranged in parallel, and the number of adsorption plates 301 can be 2 or more, and the stacking form of the two adsorption plates 301 can refer to Figure 3 On each adsorption plate 301, a plurality of adsorption ports 302 are arranged along the extension direction thereof. One end of the plurality of adsorption ports 302 is connected to the outside, and the other end is connected to at least part of the adsorption structure. When the adsorption structure 2 generates negative pressure, the workpiece is adsorbed to the adsorption port 302 through the plurality of adsorption ports 302. The shape of each adsorption port 302 is adapted to the shape of the workpiece. A flexible part is provided on the inner wall of each adsorption port 302, which may be made of rubber or other materials, so as to prevent the workpiece from being damaged when being adsorbed to the adsorption port 302.

[0052] The adsorption structure 2 has a suction space inside, and the vacuum negative pressure generated by the adsorption structure 2 can form a stable adsorption force on the adsorption member 3, thereby effectively fixing the workpiece. The design of the adsorption structure 2 fully considers the uniform distribution and air tightness of the airflow to ensure that the adsorption force is strong enough without causing damage to the workpiece. At the same time, the compactness of its structure also helps to reduce the overall size and weight of the equipment.

[0053] The adsorption member 3 is the part that directly contacts the workpiece, and includes two or more adsorption plates 301 arranged in parallel. Figure 3As shown, the number of adsorption plates 301 can be flexibly adjusted according to the number of workpieces, and each adsorption plate 301 is provided with a plurality of adsorption ports 302 arranged along its extension direction. One end of these adsorption ports 302 is connected to the outside world, and the other end is connected to the negative pressure area of ​​the adsorption structure 2 through an internal channel. When the adsorption structure 2 generates negative pressure, the workpiece (such as a U-shaped copper tube) can be stably adsorbed onto the adsorption plate 301 through the adsorption port 302. In order to prevent damage to the workpiece during the adsorption process, the present invention sets a flexible part on the inner wall of each adsorption port 302. The setting of the flexible part can effectively buffer the pressure when the workpiece contacts the adsorption structure, avoid scratches or deformation, and protect the surface quality and mechanical properties of the workpiece.

[0054] By using the above-mentioned fixing component 1, adsorption structure 2 and adsorption member 3 in combination, the receiving seat of the present invention can achieve non-destructive adsorption of the workpiece. At the same time, its lightweight design and high-efficiency vacuum adsorption system also help to reduce the manufacturing cost and operating energy consumption of the equipment, and improve production efficiency and product quality. In addition, the present invention can flexibly adapt to workpieces of different specifications and shapes by replacing adsorption members 3 of different numbers and sizes, which greatly enhances the versatility and production flexibility of the equipment.

[0055] Furthermore, the adsorption structure 2 includes: a fixing plate 201, one side of the fixing plate 201 is used to connect with the fixing component 1;

[0056] The vacuum plate body 202 is disposed on a side of the fixed plate 201 away from the fixed component 1. The vacuum plate body 202 has an adsorption space therein, and a plurality of adsorption ports 302 are connected to the adsorption space;

[0057] The vacuum component 203, at least part of which is disposed on the fixed plate 201, and the vacuum end of the vacuum component 203 is communicated with the adsorption space so that the adsorption space is in a negative pressure state.

[0058] Specifically, Figure 1 and Figure 2 As shown, the adsorption structure 2 includes a fixed plate 201, which has a rectangular structure. One side of the fixed plate 201 is used to connect with the fixed component 1. A vacuum plate body 202 is provided on the side of the fixed plate 201 away from the fixed component 1. The vacuum plate body 202 has an adsorption space. One end of a plurality of adsorption ports 302 is connected to the adsorption space. A vacuum component 203 is also provided on the fixed plate 201. The vacuum component 203 can be a vacuum machine in this embodiment. One end of the vacuum component 203 extends into the adsorption space and is connected to the adsorption space. When the vacuum machine starts working, the adsorption space can be evacuated into a negative pressure state, so the workpiece can be adsorbed to the adsorption port 302.

[0059] like Figure 1 and Figure 2As shown, the vacuum component 203 (i.e., the vacuum machine) is connected to the adsorption space in the vacuum plate 202 in the adsorption structure 2. When the vacuum machine starts working, the adsorption space can be quickly evacuated into a negative pressure state. This highly efficient vacuum adsorption method ensures that the workpiece (such as a U-shaped copper tube) can be quickly and firmly adsorbed to multiple adsorption ports 302, greatly improving the workpiece positioning speed and stability during the production process.

[0060] Since a flexible member (such as a rubber sealing sheet) is used as the contact material of the inner wall of the adsorption port 302, the receiving seat of the present invention can effectively avoid scratches, indentations and other damages when adsorbing the workpiece, thereby protecting the integrity of the workpiece surface, thereby ensuring the high quality and long life of the two devices in the refrigeration equipment.

[0061] The fixing plate 201 is made of a light and high-strength material, which not only reduces the overall weight of the receiving seat and reduces the energy consumption of the equipment, but also reduces the wear on the motor during long-term operation and extends the service life of the equipment.

[0062] The technical solution of the present invention avoids the problem of workpiece fixing caused by uneven control force in the traditional clamping method. The operator can quickly fix and release the workpiece by simply controlling the start and stop of the vacuum machine, thereby improving the automation level of the production line and the safety of operation.

[0063] In summary, the receiving seat of the present invention not only solves the problems of the traditional receiving seat system in fixing and protecting the U-tube, but also achieves improved production efficiency, reduced energy consumption and simplified operation through lightweight, flexible and precisely controlled design.

[0064] Furthermore, the vacuum plate body 202 includes: a mounting shell 2021, and mounting openings 2022 are provided at both ends of the mounting shell 2021;

[0065] The sealing component 2023 is disposed at the installation opening 2022 and is sealedly connected to the edge of the installation opening 2022 to form an adsorption space with the installation shell 2021 .

[0066] Specifically, the vacuum plate body 202 includes an installation shell 2021, which is a rectangular shell with a hollow interior. The installation openings 2022 are openings at both ends of the rectangular shell. It also includes a sealing component 2023 used in conjunction with the installation shell 2021. The sealing component 2023 can seal the two installation openings 2022 to form a sealed adsorption space.

[0067] The hollow rectangular design of the mounting housing 2021, in conjunction with the tight sealing of the openings at both ends by the sealing component 2023, ensures that a completely sealed environment is formed inside the adsorption space. This high-performance sealing structure is the key to achieving stable and efficient vacuum adsorption, which can prevent leakage of external air and ensure the vacuum degree at the adsorption port 302, thereby enhancing the adsorption force and fixing effect of the workpiece.

[0068] A uniform and stable negative pressure environment is formed inside the sealed adsorption space under the action of the vacuum component 203. This stable negative pressure state enables the workpiece to obtain a consistent adsorption force at the adsorption port 302, ensuring that the workpiece is firmly fixed even in a high-speed production environment, thereby improving the stability and safety of the production process.

[0069] Furthermore, the adsorption structure 2 further includes: a connecting component 4, the connecting component 4 includes a first connecting portion 401 and a second connecting portion 402;

[0070] A first locking member, which cooperates with the first connecting portion 401 to connect the first connecting portion 401 to the vacuum plate body 202; and / or,

[0071] The second locking member is used in conjunction with the second connecting portion 402 to connect the second connecting portion 402 to the vacuum plate body 202 .

[0072] Specifically, the adsorption structure 2 also includes a connecting component 4, which is L-shaped. The connecting component 4 includes a first connecting part 401 and a second connecting part 402, and the first connecting part 401 is perpendicular to the second connecting part 402. It also includes a first locking member, and a first locking hole is opened on the first connecting part 401. The first locking member can be inserted into the first locking hole and fix the first connecting part 401 on the vacuum plate body 202. It also includes a second locking member, and a second locking hole is opened on the second connecting part 402. The second locking member can be inserted into the second locking hole and fix the second connecting part 402 on the vacuum plate body 202, wherein the first locking member and the second locking member can be bolts, and threads are provided on the inner walls of the first locking hole and the second locking hole.

[0073] The first connection part 401 and the second connection part 402 of the L-shaped connection part 4 are vertically connected, which increases the geometric stability of the entire adsorption structure 2. The locking effect of the first locking member and the second locking member further ensures the firm connection between the connection part 4 and the vacuum plate body 202, and improves the structural stability and safety of the receiving seat in a high-speed production environment.

[0074] Bolts are used as the first locking member and the second locking member, combined with the thread design of the inner wall of the first locking hole and the second locking hole, to achieve rapid assembly and disassembly of the connecting component 4. This standardized connection method not only simplifies the initial assembly process of the equipment, but also facilitates maintenance and overhaul during the production process, reduces downtime caused by equipment failure, and improves the continuity and production efficiency of the production line. The design of the L-shaped connecting component 4 allows accurate positioning between the fixing component 1 and the vacuum plate body 202.

[0075] The design of the L-shaped connecting part 4 takes into account the optimized path of the airflow, ensuring that the vacuum system can stably and evenly draw air during the adsorption process, forming an efficient vacuum adsorption environment. The combination of the first connecting part 401 and the second connecting part 402 provides better structural support for guiding and controlling the airflow, further enhancing the adsorption effect, especially when processing complex workpieces with multiple rows of U-shaped tubes.

[0076] Further, any one of the plurality of adsorption ports 302 includes a first adsorption port 3021 and a second adsorption port 3022 ;

[0077] The adsorption member 3 further includes: a plurality of connection holes 303 provided on at least two adsorption plates 301 and located between the first adsorption port 3021 and the second adsorption port 3022;

[0078] The locking component is used in conjunction with the plurality of connecting holes 303 to fix the adsorption member 3 on the adsorption structure 2 .

[0079] Specifically, Figure 3 As shown, each adsorption port 302 includes a first adsorption port 3021 and a second adsorption port 3022. The first adsorption port 3021 and the second adsorption port 3022 are arranged side by side. A connecting hole 303 is opened in the part between the first adsorption port 3021 and the second adsorption port 3022, and also includes a locking component used in conjunction with the connecting hole 303. The locking component can be a bolt, etc., and the adsorption component 3 can be fixed on the adsorption structure 2 through the locking component.

[0080] The connection hole 303 is used in conjunction with a locking component (such as a bolt) so that the adsorption component 3 can be quickly and accurately fixed on the adsorption structure 2, and also facilitates the disassembly of the adsorption component.

[0081] The side-by-side suction port design, combined with the precise installation of the connection hole 303 and the locking component, optimizes the airflow distribution in the suction space, ensures the same vacuum degree at each suction port, and avoids the problem of insufficient suction force or damage to the workpiece due to uneven airflow. This uniform airflow distribution improves the stability and reliability of workpiece suction.

[0082] Furthermore, the adsorption member 3 further includes: a positioning pin 3023;

[0083] The positioning shaft holes are respectively arranged on at least two adsorption plates 301 , and the positioning pins 3023 are used in conjunction with the positioning shaft holes to fix and connect at least two adsorption plates 301 .

[0084] Specifically, the adsorption component 3 also includes a positioning pin 3023 , and a positioning shaft hole is opened on the two adsorption plates 301 . The positioning pin can be used in conjunction with the positioning shaft hole to fix the two adsorption plates 301 together.

[0085] The precise fit between the positioning pin 3023 and the positioning shaft hole ensures that the relative positions of the two adsorption plates 301 are accurate during the installation process. This high-precision positioning method avoids uneven distribution of adsorption force due to inaccurate component positions, improves the stability and consistency of workpiece adsorption, and ensures processing quality during the production process.

[0086] The use of the positioning pins 3023 not only provides accurate positioning, but also enhances the connection strength between the two adsorption plates 301, avoiding vibration and deformation in a high-speed production environment.

[0087] The cooperation between the positioning pin 3023 and the positioning shaft hole simplifies the installation process of the adsorption plate 301. No complicated alignment and adjustment steps are required. The installation can be completed by simply inserting the positioning pin into the shaft hole.

[0088] Furthermore, the fixing component 1 includes: a fixing base 101, a transmission structure is provided on the fixing base 101, a lifting frame body 106 is provided on the side of the transmission structure away from the fixing base 101, and the lifting frame body 106 is used to connect with the adsorption structure 2 to drive the adsorption structure 2 to move in a direction perpendicular to the fixing base 101.

[0089] Furthermore, the fixing component 1 includes a fixing seat 101, on which a transmission structure is provided, and the transmission structure is connected to a lifting frame body 106, wherein the lifting frame body 106 is used to connect with the adsorption structure 2, thereby driving the adsorption structure 2 to move in a direction vertical to the fixing seat 101.

[0090] The linkage between the lifting frame 106 and the transmission structure can accurately control the movement of the adsorption structure 2 in the vertical direction, ensuring that the adsorption member 3 can be accurately aligned with the workpiece during operation, thereby improving the positioning accuracy during the adsorption and release of the workpiece.

[0091] The combination of the transmission structure and the lifting frame 106 enables the adsorption structure 2 to flexibly adjust the relative height between it and the workpiece to meet the needs of different processing stages. For example, in the workpiece pre-processing stage, the adsorption structure 2 can be adjusted to a lower position to improve the adsorption efficiency; and in the processing or transfer stage, the adsorption structure 2 can be raised to a safe height to avoid collision with other components of the production equipment, ensuring the smooth progress of the production process.

[0092] Furthermore, the transmission structure includes: a driving component 102, the driving component 102 is arranged on the fixing seat 101, and the driving end of the driving component 102 is connected to the first gear structure;

[0093] The lead screw 104 extends in a direction perpendicular to the fixing seat 101 . A second gear structure is disposed on the lead screw 104 . The first gear structure and the second gear structure are connected via a transmission belt. One end of the lead screw 104 away from the second gear structure is connected to the lifting frame 106 .

[0094] Specifically, the transmission structure includes a driving component 102 arranged on the fixed base 101. The driving component 102 can be a driving motor. The driving end of the driving component 102 is connected to the first gear structure. One end of the lifting frame 106 is connected to the screw 104. The end of the screw 104 away from the lifting frame 106 is provided with a second gear structure. The first gear structure and the second gear structure are connected by a transmission belt. When the driving end of the driving component 102 rotates, the first gear structure rotates synchronously with it, and the second gear structure also rotates synchronously with it. Because the positions of the first gear structure and the second gear structure are relatively fixed, the screw 104 will move in a direction perpendicular to the fixed base 101, so it can drive the lifting frame 106 to move.

[0095] The driving component 102 can achieve high-precision control of the vertical movement of the lifting frame 106 through precise synchronization of the first gear structure and the second gear structure on the lead screw 104. This transmission method through the gear and the lead screw 104 ensures that the position adjustment of the lifting frame 106 in the vertical direction has extremely high accuracy, which is conducive to improving the processing quality and production efficiency of the workpiece.

[0096] The first gear structure is connected to the second gear structure through a transmission belt. This design can ensure that the torque of the driving component 102 is smoothly transmitted to the screw 104, avoiding the impact and vibration during the movement of the lifting frame 106, ensuring the stability of the adsorption structure 2 during vertical movement, reducing the risk of damage to the workpiece during the lifting process, and improving the stability and reliability of the production process.

[0097] The combination of gear transmission and lead screw 104 can achieve more efficient energy conversion compared to other transmission methods. The rotational kinetic energy of the drive motor is amplified by the gear structure and converted into the linear motion of the lead screw 104. This energy conversion method reduces energy loss, improves the energy efficiency of the equipment, and reduces production costs.

[0098] Furthermore, the fixing component 1 further comprises:

[0099] A first support plate 107, the first support plate 107 is disposed on the fixed base 101, the extension direction of the first support plate 107 is perpendicular to the extension direction of the fixed base 101, and the transmission structure is disposed on the first support plate 107;

[0100] At least two second support plates 108, the at least two second support plates 108 are disposed on one side of the first support plate 107 and arranged along the extension direction of the fixing base 101;

[0101] A sliding track, which is arranged on a side of at least two second support plates 108 away from the first support plate 107;

[0102] The sliding block 109 is disposed on the lifting frame 106 , and the sliding block 109 is slidably connected to the sliding track.

[0103] Specifically, the fixing component 1 also includes a first support plate 107 arranged on the fixing seat 101, and the extension direction of the first support plate 107 is perpendicular to the extension direction of the fixing seat 101, wherein the transmission structure is arranged on the first support plate 107, and at least two second support plates 108 are arranged on the side of the first support plate 107 close to the lifting frame body 106, and the two second support plates 108 are arranged along the extension direction of the fixing seat 101, and a sliding track is provided on the side of the second support plate 108 away from the first support plate 107, and a sliding block 109 is slidably connected in the sliding track, and the end of the sliding block 109 away from the sliding track is connected to the lifting frame body 106, wherein the driving component 102 is arranged on the side of the first support plate 107 away from the lifting frame body 106.

[0104] The first support plate 107 extends vertically from the fixing seat 101, providing a stable installation platform for the transmission structure, ensuring the stability and reliability of the driving component 102 during operation. The second support plate 108 is provided to further strengthen the lateral support of the structure, so that the entire fixing component 1 has higher rigidity when subjected to vertical force, reduces structural deformation and vibration, and improves the long-term operation stability of the equipment.

[0105] The movement of the sliding block 109 in the sliding track and the connection with the lifting frame 106 realize the precise linear movement of the adsorption structure 2 in the vertical direction. This design avoids the lateral shaking that may occur in the traditional mechanical structure, ensures the smooth movement of the lifting frame 106 in the vertical direction, and improves the accuracy of workpiece adsorption and release.

[0106] The driving component 102 is disposed on a side of the first support plate 107 away from the lifting frame body 106 , thereby preventing the driving component 102 from directly bearing a vertical load and reducing energy loss during power transmission.

[0107] The modular design of the first support plate 107 and the second support plate 108 makes maintenance and adjustment easier. When the transmission structure or the sliding track needs to be maintained, the first support plate 107 and the second support plate 108 can be operated independently without disassembling the entire device, reducing maintenance time and cost. In addition, the adjustable design of the sliding track and the sliding block 109 allows the vertical movement path of the adsorption structure 2 to be fine-tuned during the operation of the device, enhancing the adaptability and flexibility of the device.

[0108] According to another aspect of the present invention, a tube expander is provided, on which the above-mentioned receiving seat is provided.

[0109] The present application also provides a tube expander having the above-mentioned receiving seat.
