[0002] In the air conditioning industry, the support plate is the main supporting component for the high-efficiency heat exchange tubes in the shell and tube of the pressure vessel. At present, the assembly method of the high-efficiency heat exchange tubes is to insert the heat exchange tubes one by one from the tube plate hole, pass through the support plate tube hole inside the container, and then pass through the tube plate hole at the other end.

[0040] In the commercial air-conditioning industry, the support plate 40 is the main supporting component for the high-efficiency heat exchange tubes in the shell and tube of the pressure vessel, and its coaxiality plays a vital role in the assembly process of the heat exchange tubes. At present, the assembly of high-efficiency heat exchange tubes usually adopts the method of inserting the heat exchange tubes one by one from the tube sheet hole, passing through the tube hole of the support plate 40 inside the container, and then passing out from the tube sheet hole at the other end. However, this assembly process has extremely high requirements for the coaxiality of the support plate 40, because the accuracy of the coaxiality is directly related to whether the heat exchange tube can be smoothly inserted and work efficiently. If the coaxiality of the support plate 40 is poor, it will not only make it difficult to insert the heat exchange tube during assembly, but also may cause the heat exchange tube to bend during the assembly process. When further compressed, this bending may cause the heat exchange tube to break and break, thereby seriously affecting the normal operation and safety of the air-conditioning system. Therefore, ensuring the accurate coaxiality of the support plate 40 is a key problem that needs to be solved in the commercial air-conditioning industry. To this end, the utility model inventor has proposed the following improvement plan after research, which is explained below.

[0041] See also Figures 1 to 3 The embodiment of the utility model provides a coaxial support plate assembly device, including: a tooling frame 10, which is horizontally provided with a first slide rail 11; a positioning trolley 20, which is slidably connected to the first slide rail 11, and a support plate positioning structure 21 for positioning a support plate 40 is provided on the positioning trolley 20. The positioning trolley 20 is provided with at least two support plate positioning structures 21 on different positioning trolleys 20, and the support plates 40 on different support plate positioning structures 21 are coaxially arranged and have the same height, so that the support plates 40 located on different support plate positioning structures 21 have the same height and the central axes coincide. A bolt hole is provided on the support plate 40, and a bolt 41 is inserted into the bolt hole to fix and lock the support plate 40. The bolt 41 is a special bolt.

[0042] The present embodiment provides a support plate coaxial assembly device, whose main function is to ensure that during the manufacturing process of air conditioners or other similar equipment, the support plate 40 can be accurately and efficiently coaxially positioned. This coaxial positioning is a key step to ensure the smooth assembly of the subsequent heat exchange tubes, improve the assembly accuracy and the overall performance of the air conditioning system. Specifically, the first slide rail 11 on the tooling frame 10 provides a stable sliding track for the positioning trolley 20, ensuring that the positioning trolley 20 can move in a straight line, and can simulate the spacing of the support plates 40 during the assembly of the heat exchange tubes. The support plate positioning structures 21 on different positioning trolleys 20 are coaxially arranged and have the same height, ensuring that when the support plate 40 is placed on the support plate positioning structure 21, the support plates 40 on different positioning trolleys 20 can be coaxially positioned.

[0043] For further information, see Figure 4 and Figure 5The positioning trolley 20 includes a moving component 22 and a frame 23 arranged on the moving component 22. The moving component 22 is slidably connected to the first slide rail 11. The support plate positioning structure 21 includes a horizontal positioning member 211 horizontally arranged on the frame 23 and a vertical positioning member 212 vertically arranged on the frame 23. The bottom of the support plate 40 is supported on the horizontal positioning member 211, and the side of the support plate 40 leans on the vertical positioning member 212.

[0044] In this embodiment, the horizontal positioning member 211 provides bottom support for the support plate 40 through its horizontal surface, ensuring that the support plate 40 can be stably placed on the positioning trolley 20. The vertical positioning member 212 provides a support for the side of the support plate 40 through its vertical surface, so that the support plate 40 can be better positioned on the positioning trolley 20, further enhancing the stability of the support plate 40. Specifically, the horizontal positioning member 211 is horizontally arranged with the first slide rail 11, and the vertical positioning member 212 is vertically arranged with the first slide rail 11, and there are multiple vertical positioning members 212, and the multiple vertical positioning members 212 are arranged at intervals on the positioning trolley 20, and are perpendicular to the horizontal positioning member 211. When the support plate 40 is placed on the positioning trolley 20, the bottom of the support plate 40 will naturally be placed on the horizontal positioning member 211, and the side of the support plate 40 will lean on the vertical positioning member 212. It can be understood that the horizontal positioning members 211 on different positioning carts 20 have the same height, so that the support plates 40 on different positioning carts 20 have the same height.

[0045] Optionally, the motion assembly 22 includes a first drive device, a rotating shaft, and a gear. A rack parallel to the first slide rail 11 is provided on the tooling frame 10, the gear is meshed with the rack, the rotating shaft is passed through the gear and fixed to the gear, the power output end of the first drive device is connected to the rotating shaft, the rotating shaft is driven to rotate by the first drive device, and the rotation of the rotating shaft drives the gear to rotate. Due to the meshing connection between the gear and the rack, the positioning trolley 20 can slide along the rack and the first slide rail 11. Optionally, the first drive device can be a hand wheel rotated manually, or it can be a motor.

[0046] Furthermore, the support plate positioning structure 21 includes a positioning pin assembly 213, which is used to fix and lock the support plate 40. When the support plate 40 is located on the support plate positioning structure 21, the support plate 40 is fixed and locked by the positioning pin assembly 213, which can ensure that the position of the support plate 40 remains unchanged during the movement of the positioning trolley 20, and at the same time ensure that the position remains unchanged after welding with the pull rod 50, thereby ensuring the stability of the coaxiality of the support plate 40 on different positioning trolleys 20.

[0047] For details, please refer to Figure 6 , Figure 8 and Fig. 9The positioning pin assembly 213 includes: a bracket 2131, a sliding rod 2132, a first slider 2133, a connecting plate 2134, a positioning pin 2135 and a positioning pin head 2136. The sliding rod 2132 is vertically arranged on the bracket 2131. The first slider 2133 is slidably connected to the sliding rod 2132. The connecting plate 2134 is fixed to the first slider 2133. A through hole is opened on the connecting plate 2134. A heat exchange tube hole 42 is opened on the support plate 40. One end of the positioning pin 2135 passes through the through hole and the heat exchange tube hole 42 and is screwed to the positioning pin head 2136.

[0048] In this embodiment, the sliding rod 2132 is fixed on the bracket 2131, and the first sliding block 2133 is connected to the sliding rod 2132. The first sliding block 2133 can slide up and down along the sliding rod 2132. When the first sliding block 2133 slides to a suitable position, the perforation on the connecting plate 2134 is coaxial with the heat exchange tube hole 42 on the support plate 40. The positioning pin 2135 can pass through the perforation on the connecting plate 2134 and the heat exchange tube hole 42 on the support plate 40 to achieve the positioning of the support plate 40. At the other end of the positioning pin 2135, the positioning pin head 2136 is screwed to fix the positioning pin 2135 on the support plate 40 to ensure that the support plate 40 will not be displaced or shaken in subsequent operations. After the support plate 40 is fixed, the subsequent assembly of the pull rod 50 and other operations can be continued. Since the support plate 40 has achieved stable and accurate positioning, the assembly accuracy and efficiency can be greatly improved. It should be noted that the locating pins 2135 on different positioning trolleys 20 are set at the same height and are coaxial. Since the locating pin assembly 213 can slide up and down, the height of the locating pin 2135 can be adjusted; the locating pins 2135 are coaxial at the same height; since the processing accuracy of the positions of the heat exchange tube holes 42 of the support plates of the same support plate assembly is very high, in practice, it is only necessary to insert the locating pins 2135 into the heat exchange tube holes 42 of the same column of each support plate to achieve the coaxiality of each support plate of the support plate assembly.

[0049] For further information, see Figures 7 to 10The coaxial assembly device of the support plate 40 of the present scheme also includes a tie rod positioning assembly 30 and a tie rod 50. The tie rod positioning assembly 30 is arranged at one end of the first slide rail 11 and faces the side of the positioning trolley 20, and is used to support one end of the tie rod 50. A tie rod hole 43 is opened on the support plate 40 for the other end of the tie rod 50 to pass through. When one end of the tie rod 50 is supported by the tie rod positioning assembly 30 and the other end passes through the tie rod hole 43 of the support plate 40, the tie rod 50 can provide additional support and fixation for the support plate 40. This three-point support structure can ensure the stability and coaxiality of the support plate 40 during the assembly process. During the coaxial positioning process of a support plate 40, the support plate 40 is first placed on the horizontal positioning piece 211 and the vertical positioning piece 212 of the positioning trolley 20, and is initially fixed using the positioning pin assembly 213. One end of the pull rod 50 is then placed on the pull rod positioning assembly 30 to ensure that the pull rod 50 is in stable contact with the pull rod positioning assembly 30. Then, the other end of the pull rod 50 is passed through the pull rod hole 43 on the support plate 40 so that the pull rod 50 passes through the support plate 40, making the coaxiality of each support plate 40 more precise and stable.

[0050] Furthermore, the pull rod positioning assembly 30 includes: a frame 31, a second slide rail 32 and an adjustment assembly 33, the adjustment assembly 33 includes a slide plate 331, a second slider 332 and a driving assembly 34, the second slide rail 32 is vertically arranged on the frame 31, the slide plate 331 is horizontally arranged on the second slide rail 32, the driving assembly 34 is connected to the slide plate 331, the second slider 332 is slidably connected to the slide plate 331, and the second slider 332 is provided with a groove 3321 for supporting the pull rod 50. It should be explained that the second slide rail 32 is vertically arranged on the frame 31, providing a sliding track in the vertical direction for the slide plate 331, and the slide plate 331 is horizontally arranged on the second slide rail 32 and connected to the second slide rail 32, and can slide up and down along the second slide rail 32. The driving component 34 is connected to the slide plate 331 to provide power for the sliding of the slide plate 331. By controlling the driving component 34, the position of the slide plate 331 can be accurately adjusted. The second slider 332 is slidably connected to the slider 331, and can slide horizontally along the slider 331 to adjust its position as needed. The groove 3321 set on the second slider 332 is used to support one end of the pull rod 50, and the shape and size of the groove 3321 match the pull rod 50 to ensure that the pull rod 50 can be stably placed in the groove 3321. It can be understood that the groove 3321 set on the second slider 332 in the present embodiment is a groove 3321 with the notch direction facing vertically upward. When it is necessary to insert the pull rod 50, the support plate 40 on the positioning trolley 20 close to the pull rod positioning assembly 30 should be brought close to the second slider 332, so that the pull rod hole 43 on the support plate 40 is aligned with the groove 3321 on the second slider 332, so that when the pull rod 50 is subsequently inserted, it can smoothly pass through the second slider 332 and the support plates 40 on each positioning trolley 20.

[0051] In this embodiment, two second slide rails 31 are provided, and are respectively vertically arranged on both sides of the frame 31 , so that the slide plate 331 can stably slide horizontally on the two second slide rails 31 .

[0052] Furthermore, a plurality of adjustment components 33 are provided along the second slide rail 32. It should be explained that the rod holes 43 on the support plate 40 are provided in a plurality of rows. When the number of adjustment components 33 is one, only a single row of rod holes 43 can be inserted into the rod 50 at a time, and the work efficiency is low. In the present embodiment, a plurality of adjustment components 33 are provided along the second slide rail 32, which means that a plurality of adjustment components 33 can correspond to a plurality of parallel rows of rod holes 43 on the support plate 40, and a plurality of rows of rod holes 43 can be inserted into the rod 50 at a time, and the work efficiency is improved.

[0053] Specifically, two adjustment assemblies 33 are provided, which are respectively arranged at the upper and lower ends of the pull rod positioning assembly 30 and are arranged vertically with the second slide rail 31. The two slide plates 331 are horizontally slidably connected to the two second slide rails 31. The adjustment assemblies 33 at the upper and lower ends can be moved up and down on the second slide rail 31 by a driving device, so that the pull rod positioning assembly 30 is more stable. The driving device power source of the upper adjustment assembly 33 is a servo motor, and the driving device power source of the lower adjustment assembly 33 is a manually rotating hand wheel.

[0054] Furthermore, multiple second sliders 332 are arranged side by side. It should be explained that multiple pull rod holes 43 on the support plate 40 are arranged in a row, which can reduce the adjustment and movement distance of the second slider 332. Preferably, there are at most three pull rod holes 43 on the support plate 40 in a row, and the distribution of pull rod holes 43 in different rows may be different. In order to align the grooves 3321 on the second slider 332 with the pull rod holes 43 in different rows, it is necessary to adjust the position of the second slider 332. Since the number of second sliders 332 exceeds the number of pull rod holes 43, it is possible to insert the pull rod 50 into all the pull rod holes 43 at a time. Therefore, multiple second sliders 332 in this embodiment are arranged side by side, which means that when the pull rod 50 is inserted into more pull rod holes 43 on the support plate 40 at a time, the pull rod 50 can be inserted, which improves work efficiency.

[0055] In one embodiment, the positioning trolley 20 close to the tie rod positioning assembly 30 is the first positioning trolley 201, and the other positioning trolleys 20 are the second positioning trolleys 202. The horizontal positioning member 211 of the first positioning trolley 201 faces one side of the tie rod positioning assembly 30, and the width of the horizontal positioning member 211 of the first positioning trolley 201 is smaller than the width of the horizontal positioning member 211 of the second positioning trolley 202. In one embodiment, the total number of positioning trolleys 20 is four, of which one first positioning trolley 201 is provided and three second positioning trolleys 202 are provided.

[0056] It should be explained that in the coaxial assembly device of the support plate 40 of the present embodiment, the positioning trolley 20 close to the tie rod positioning assembly 30 is designed as the first positioning trolley 201, and the horizontal positioning member 211 of the first positioning trolley 201 is designed to face the side of the tie rod positioning assembly 30, while reducing its width. Such design changes are intended to improve the support plate 40 on the first positioning trolley 201 and the second slider 332 of the tie rod positioning assembly 30 to be closer, so that the tie rod hole 43 on the support plate 40 and the groove 3321 on the second slider 332 can be more easily aligned, so that the tie rod 50 can more easily pass through the gap between the first positioning trolley 201 and the tie rod positioning assembly 30, which is convenient for the installation of the tie rod 50. The horizontal positioning member 211 of the second positioning trolley 202 has a larger width, which can provide a wider support surface and enhance the stability of the support plate 40.

[0057] Furthermore, the positioning trolley 20 is provided with a locking assembly for locking the positioning trolley 20 on the first slide rail 11. When the positioning trolley 20 needs to be fixed at a certain position, the positioning trolley 20 is firmly locked on the first slide rail 11 through the locking assembly, which can effectively prevent the position of the positioning trolley 20 from shifting during the assembly process, thereby ensuring the accuracy and stability of the assembly. It is understandable that the locking assembly is used to lock the positioning trolley 20 on the first slide rail 11, and the locking assembly can refer to various solutions of the prior art, such as structures such as electric control locks.

[0058] Specifically, a coaxial positioning process of a support plate 40 includes: S1, placing the support plate 40 on the horizontal positioning member 211 so that it is close to the vertical positioning member 212; S2, selecting a suitable positioning pin 2135 according to the size of the heat exchange tube hole 42 on the support plate 40, aligning one end of the positioning pin 2135 with the through hole of the connecting plate 2134 and the heat exchange tube hole 42 of the support plate 40, inserting and screwing it to the positioning pin head 2136, tightening the positioning pin head 2136 so that the support plate 40 is clamped on the connecting plate 2134; S3, executing the above steps S1 and S2 on all positioning trolleys 20, at which time the support plates 40 on all positioning trolleys 20 are of the same height and coaxial; S4, driving the first positioning trolley 201 to move on the first slide rail 11 towards the direction close to the pull rod positioning assembly 30, so that the support plate 4 0 is close to the second slider 332 on the tie rod positioning assembly 30; S5, according to the position of the tie rod hole 43 on the support plate 40, the position of the slide plate 331 and the second slider 332 is adjusted to align the groove 3321 on the second slider 332 with the tie rod hole 43 on the support plate 40; S6, drive the first positioning trolley 201 and the second positioning trolley 202 to slide on the first slide rail 11, so that the distance between the first positioning trolley 201 and the tie rod positioning assembly 30, the distance between the first positioning trolley 201 and the second slider 332, the distance between the first positioning trolley 201 and the second positioning trolley 202, and the distance between the second positioning trolley 202 are consistent with the arrangement of the support plate 40 in the shell tube of the air-conditioning pressure vessel, and all the positioning trolleys 20 are stationary on the first slide rail 11 through the locking assembly; S7, insert the tie rod 50 to obtain a highly coaxial support plate assembly.

[0059] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0060] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive.
