[0040] The following will further describe in detail a pipeline model for installing a catheter at a docking position of the present invention in conjunction with the accompanying drawings:

[0041] The wing of an aircraft is divided into two parts, wing part 1 and wing part 2. The ducts need to be installed on wing parts 1 and 2 respectively. After the two wing parts are butted, the ducts are butted through flanges (see Figure 1 ), this patented tool can achieve smooth docking of the catheter, and the specific implementation method is as follows:

[0042] According to the attached Figure 8 , 9 As shown, after the wing component 1 is processed on the butt joint surface, the pipeline mold 1 is installed, and the pipeline model is fixed on the wing butt joint surface through the connecting plate 1a, connecting pin 1b, butt joint hole protection bushing 1c, and handle nut 1d. Fig. 9 In the A and BB sections, the positioning rod 4a can move telescopically along the shaft sleeve 2a to ensure that the pipeline model is easy to disassemble and has good processability. The telescopic amount is controlled by the positioning pin 3. The positioning rod 4a and the shaft sleeve 2a are provided with mounting holes for the positioning pin 3. The positioning pin 3 is installed to place the positioning rod 4a in the theoretical position. The structural form of the positioning rod 4a is as follows Figure 7 As shown, the end is in the shape of a ball head, which can simulate the ball head of the conduit on component 2. The bell mouth of the conduit of component 1 is fixed with the ball head and flange on the positioning rod 4a by connecting bolts 4b to simulate the conduit docking state. After the position of the pipe mouth is fixed, the direction of the conduit is adjusted to achieve the optimal state with the surrounding structure and system gap. Then the conduit is fixed with the fixing bracket and clamp to complete the positioning installation of the conduit on component 1.

[0043] According to the attached Figure 8As shown in FIG. 1 , after the wing component 2 is processed on the butt joint surface, the pipeline model 2 is installed, and the pipeline model is fixed on the wing butt joint surface through the connecting plate 5a, the connecting pin 5b, and the handle nut 5c. Figure 2 The positioning rod 6a can perform axial telescopic movement along the shaft sleeve hole on 5a to ensure that the pipeline model is easy to disassemble and has good processability. The telescopic amount is controlled by the positioning pin 6b. The mounting hole of the positioning pin 6b is set on 5a. The positioning pin 6b is installed to put the positioning rod 6a in the theoretical position. The end of the positioning rod 6a is trumpet-shaped, which is consistent with the trumpet of the product conduit and can simulate the trumpet of the conduit on component 1. Use the connecting bolt 6c to fix the ball head of the conduit of component 2 to the trumpet and flange on the positioning rod 6a to simulate the docking state of the conduit. After the position of the pipe mouth is fixed, adjust the direction of the conduit so that the gap between it and the surrounding structure and system reaches the optimal state, and then fix the conduit to the fixed bracket and clamp to complete the positioning and installation of the conduit on component 2.

[0044] Use pipeline models 1 and 2 to locate the position of the conduit orifice and fix the conduit, simulate the conduit docking state, and when component 1 and component 2 are docked, the conduit at this docking position can be smoothly docked and installed. This solves the problem of inability to dock and install due to incoordination of the conduits, and improves the conduit installation efficiency and assembly quality.

[0045] This pipeline model has a simple structure and adopts an integral structure. The pipeline model is fixed by the docking bolt holes on the docking surface. The pipeline model is used to simulate the docking state of the catheter and locate the position of the pipe port. The pipeline model has a simple structure and is easy to operate. The present invention sets a pipeline model on each wing docking component, and each component uses the pipeline model to locate the docking pipe port position based on the docking surface. When the wings are docked, the catheter can be docked smoothly.

[0046] like Figure 1 This is a schematic diagram of the product duct docking position. The spherical pipe opening and the trumpet-shaped pipe opening are fixed to the duct docking by flanges and fixing bolts.

[0047] like Figure 2 A pipeline model is provided as shown, and the pipeline model is set at 2 locations. The pipeline model is used to simulate the catheter docking state in the assembly stage of component 1 and component 2, respectively, to complete the positioning and installation of the catheter in each component. The structure of the pipeline model 1 includes a connecting plate assembly 1, a positioning sleeve assembly 2, a positioning pin 3, and a positioning rod assembly 4; the structure of the pipeline model 2 includes a connecting plate assembly 5 and a positioning assembly 6.

[0048] The connecting plate assembly 1 includes a connecting plate 1a ( Figure 3 )、3 connecting pins 1b、3 docking hole protection bushings 1c( Figure 4 )、3 handle nuts 1d( Figure 5 );

[0049] The positioning sleeve assembly 2 includes a sleeve 2a ( Figure 6 ), 4 fixing screws 2b;

[0050] The positioning pin 3 is used to control the telescopic amount of the positioning rod assembly 4 relative to the positioning sleeve assembly 2; the positioning sleeve assembly 2 is fixedly connected to the connecting plate 1a in the connecting plate assembly 1.

[0051] The positioning rod assembly 4 includes a positioning rod 4a (such as Figure 7 As shown, its shape is a ball head, which is used to position the bell mouth of the conduit), 3 connecting bolts 4b ( Fig. 9 section view).

[0052] The connecting plate assembly 5 includes a connecting plate 5a ( Fig.10 ), 3 connecting pins 5b, 3 handle nuts 5c;

[0053] The positioning assembly 6 includes a positioning rod 6a (which is trumpet-shaped and functions to position the catheter ball head), a positioning pin 6b, and three connecting pins 6c.

[0054] After the butt joint surfaces of wing parts 1 and 2 are processed, use the butt joint holes to install pipeline models 1 and 2 (see Figure 8 , Fig. 9 ), use the pipeline model to simulate the pipe opening docking state, adjust the direction of the duct according to the positioning rod assembly 4 and positioning assembly 6 on the pipeline model, simulate the duct docking state, control the position of the pipe opening, and ensure the clearance requirements with the surrounding structure and system parts. After the wing docking, the pipeline can be docked and installed smoothly.

[0055] The structural forms of Model 1 and Model 2 are roughly the same. To ensure that the size of the positioning nozzle of the pipeline model is consistent with the docking surface, the shapes of the connecting plates 1a and 5a in Model 1 and Model 2 are different. The rest of the structural forms are roughly the same.

[0056] A pipeline model for catheter installation of the present invention specifically relates to a catheter positioning and installation device at an aircraft docking position, which has a simple structure and is easy to disassemble and assemble. It adopts a quick-release connection with the docking surface, is easy to disassemble and assemble, and is easy to operate. It has good processability and can achieve smooth docking and installation of catheters at the docking position of components, solves the problem of being unable to dock and install due to incoordination of the catheters, avoids the problem of resampling and manufacturing of the catheters, reduces the rework rate of the catheters, achieves early production and delivery of the catheters, and improves the installation efficiency and assembly quality of the catheters.
