[0034] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0036] The present invention provides a fuel manifold nozzle tooling, comprising a connecting rod assembly, a connecting plate 10 and a support seat 20. The connecting rod assembly is used to connect with the fuel manifold nozzle joint, the connecting plate 10 is rotatably connected to the connecting rod assembly, the support seat 20 is used to connect with the casing, the support seat 20 is used to support the connecting plate 10, and the support seat 20 is rotatably connected to the connecting plate 10, and the rotation axis of the connecting plate 10 relative to the support seat 20 is a first axis perpendicular to the support surface of the support seat 20 on the connecting plate 10.

[0037] By arranging the connecting plate 10 and the connecting rod assembly to be relatively rotatable, the orientation of the connecting rod assembly relative to the casing can be adjusted so as to connect with the fuel manifold nozzle joints at different positions. A support seat 20 that can rotate relative to the connecting plate 10 is further arranged, and the first axis is arranged to be perpendicular to the support surface of the support seat 20 for the connecting plate 10. This ensures that while the position of the support seat 20 relative to the casing remains unchanged, the orientation of the connecting plate 10 and the connecting rod assembly as a whole can be adjusted relative to the casing, further improving the flexibility of the fuel manifold nozzle tooling of the present invention and expanding its scope of application, so that it can be suitable for the assembly of fuel manifolds of different specifications and shapes, avoiding the cumbersome steps of producing different tooling for different fuel manifolds, thereby greatly reducing the relevant production and manufacturing costs.

[0038] like Figure 1 As shown, in some embodiments, the connecting rod assembly includes a first connecting rod 30 and a second connecting rod 40, the first connecting rod 30 is rotatably connected to the connecting plate 10, and the rotation axis of the first connecting rod 30 relative to the connecting plate 10 is a second axis perpendicular to the first axis, one end of the second connecting rod 40 is ball-jointedly connected to the first connecting rod 30, and the other end of the second connecting rod 40 is used to connect to the fuel main nozzle joint.

[0039] By setting the first link 30 and the second link 40, the adjustment freedom of the angle and height of the link assembly is further increased. The orientation of the first link 30 and the second link 40 can be adjusted simultaneously by rotating the first link 30. If the second link 40 and the first link 30 are set as a ball joint connection, the orientation of the link assembly can be adjusted within a larger angle range by rotating the second link 40.

[0040] In some embodiments, in the extension direction of the second axis, the distance between the end of the first connecting rod 30 away from the connecting plate 10 and the connecting plate 10 is adjustable.

[0041] like Figure 1 As shown, by setting the distance between the end of the first connecting rod 30 away from the connecting plate 10 and the connecting plate 10 to be adjustable in the extension direction of the second axis, the overall width of the fuel main pipe nozzle tooling can be adjusted.

[0042] In some embodiments, the first connecting rod 30 is connected to the connecting plate 10 by threads, and the length of the threaded connection is adjustable.

[0043] like Figure 2 As shown, the connecting plate 10 is provided with a threaded hole, and the first connecting rod 30 is provided with an external thread matching the threaded hole of the connecting plate 10. By rotating the first connecting rod 30, the length of the threaded connection can be adjusted, thereby adjusting the overall width of the fuel manifold nozzle tooling, and the overall orientation of the connecting rod assembly can also be adjusted. Among them, the first connecting rod 30 is also provided with an external hexagonal structure, so that the length of the threaded connection between the first connecting rod 30 and the connecting plate 10 can be adjusted by using a tool such as a hexagonal wrench.

[0044] In addition to the threaded connection, other rotatable connection methods may be used between the first connecting rod 30 and the connecting plate 10 , as long as the relative angle between the first connecting rod 30 and the connecting plate 10 can be changed.

[0045] In addition to the above solution, other methods may be used to adjust the distance between the end of the first connecting rod 30 away from the connecting plate 10 and the connecting plate 10 .

[0046] In some embodiments, the first connecting rod 30 includes a retractable adjustment structure, such as a sleeve rod structure, a pull rod structure, a compressible elastic structure, etc.

[0047] In some embodiments, the length of the second connecting rod 40 is adjustable.

[0048] By setting the length of the second connecting rod 40 to be adjustable, the overall height of the connecting rod assembly can be adjusted within a larger range, further improving the applicability of the fuel manifold nozzle tooling of the present invention.

[0049] To achieve adjustable length of the second connecting rod 40, a variety of feasible solutions can be adopted, such as configuring the second connecting rod 40 to include a telescopic pull rod structure, or configuring the second connecting rod 40 to include a telescopic elastic structure, or configuring the second connecting rod 40 to include a multi-section structure with detachable connections, etc.

[0050] like Figure 3 As shown, in some embodiments, the second connecting rod 40 includes an outer rod 41 and an inner rod 42, the outer rod 41 is used to connect to the fuel main nozzle joint, one end of the inner rod 42 is rotatably connected to the first connecting rod 30, and the other end of the inner rod 42 is embedded in the outer rod 41 and the embedding depth is adjustable.

[0051] By configuring the second connecting rod 40 to include an outer rod 41 and an inner rod 42, the purpose of changing the overall length of the second connecting rod 40 by changing the relative positional relationship between the outer rod 41 and the inner rod 42 can be achieved. In this embodiment, the outer rod 41 and the inner rod 42 are connected by internal and external threads, and the overall length of the second connecting rod 40 can be adjusted by adjusting the length of the threaded connection. The outer rod 41 is also provided with an external hexagonal structure, so that the length of the threaded connection between the outer rod 41 and the inner rod 42 can be adjusted by using a tool such as a hexagonal wrench.

[0052] like Figure 1 As shown, in some embodiments, the fuel manifold nozzle tooling also includes a first joint structure 50 for realizing a ball joint connection, the first joint structure 50 includes a first outer ring 51 and a first inner ring 52, the first outer ring 51 is connected to the first connecting rod 30, the first inner ring 52 is connected to the second connecting rod 40, and the first outer ring 51 and the first inner ring 52 are spherically matched.

[0053] Specifically, the first joint structure 50 is a damped ball joint structure, the inner surface of the first outer ring 51 includes a part of a spherical surface, the outer surface of the first inner ring 52 includes a part of a spherical surface, the first outer ring 51 is sleeved on the outer periphery of the first inner ring 52, and the first outer ring 51 and the first inner ring 52 can realize relative rotation with damping, that is, the first outer ring 51 and the first inner ring 52 can realize full-degree-of-freedom rotation and limit positioning, so that the relative rotation between the first connecting rod 30 and the second connecting rod 40 can be realized through the first joint structure 50, and after the second connecting rod 40 is rotated to a suitable position, the first connecting rod 30 and the second connecting rod 40 can remain relatively fixed.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the connecting rod assembly further includes a third connecting rod 60 and a fourth connecting rod 70. The third connecting rod 60 is ball-jointedly connected between the second connecting rod 40 and the fourth connecting rod 70. The fourth connecting rod 70 is used to connect to the fuel main nozzle joint.

[0055] The ball joint connection between the second link 40 and the third link 60 and between the third link 60 and the fourth link 70 can be realized by a damping ball joint structure similar to the first joint structure 50, or by other structures capable of realizing ball joint connection.

[0056] like Figure 1 to Figure 3 As shown, the second connecting rod 40 and the third connecting rod 60 are connected by a second joint structure 90 to achieve a ball joint connection. The second joint structure 90 includes a second outer ring 91 and a second inner ring 92 which can rotate relative to each other. The second inner ring 92 is connected to the third connecting rod 60. The second outer ring 91 and the outer rod 41 of the second connecting rod 40 are fixedly connected. The second outer ring 91 and the outer rod 41 can be an integrally formed structure or can be connected by welding, plug-in, etc., as long as it is ensured that there is no relative movement between the second outer ring 91 and the outer rod 41 after assembly is completed.

[0057] like Figure 1 and Figure 2 As shown, the third connecting rod 60 and the fourth connecting rod 70 are ball-jointed via a third joint structure 100. The third joint structure 100 includes a third outer ring 110 and a third inner ring 120 which can rotate relative to each other. The third inner ring 120 is connected to the fourth connecting rod 70. The third outer ring 110 and the third connecting rod 60 are fixedly connected. The third outer ring 110 can be integrally formed with the third connecting rod 60, or can be connected by welding, plug-in, etc., as long as no relative movement occurs between the third outer ring 110 and the third connecting rod 60 after assembly is completed.

[0058] like Figure 2 As shown, in some embodiments, one end of the fourth connecting rod 70 away from the third connecting rod 60 includes a spherical structure for connecting with a fuel manifold nozzle joint.

[0059] The spherical structure can achieve a more fitting connection between the fourth connecting rod 70 and the fuel main nozzle joint, and facilitates adjustment of the angle of the connection between the fourth connecting rod 70 and the fuel main nozzle joint, so as to facilitate the smooth progress of the subsequent assembly process.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the second link 40 includes a first limiting structure 43 connected to the first link 30, and the first limiting structure 43 is used to limit the movement of the second link 40 relative to the first link 30 in its length direction.

[0061] Specifically, the first limiting structure 43 includes a column for cooperating with the first inner ring 52 of the first joint structure 50 and a flange portion extending radially outward from the outer peripheral surface at both ends of the column, thereby limiting the movement of the second connecting rod 40 relative to the first joint structure 50 along the axial direction of the column to ensure the overall stability of the connecting rod assembly.

[0062] like Figure 2 As shown, the third link 60 includes a second limiting structure 61 connected to the second link 40, and the second limiting structure 61 is used to limit the movement of the third link 60 relative to the second link 40 in its length direction; the fourth link 70 includes a third limiting structure 71 connected to the third link 60, and the third limiting structure 71 is used to limit the movement of the fourth link 70 relative to the third link 60 in its length direction. Among them, the second limiting structure 61 and the third limiting structure 71 can adopt a structure similar to the first limiting structure 43.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the fuel manifold nozzle tooling also includes an adjustment seat 80, the adjustment seat 80 includes a limiting portion 81 and a connecting portion 82, the connecting plate 10 is rotatably mounted on the outer periphery of the limiting portion 81, the limiting portion 81 is used to limit the movement of the connecting plate 10 relative to the adjustment seat 80 in the first axial direction, and the connecting portion 82 is connected to the support seat 20.

[0064] Specifically, the connecting plate 10 is provided with a connecting hole, and the limiting portion 81 includes a column and a flange portion extending radially outward from the outer circumferential surface of both ends of the column, and there is a clearance fit between the column and the connecting hole of the connecting plate 10, so that while the connecting plate 10 can rotate relative to the adjusting seat 80, the relative movement of the connecting plate 10 along the axial direction of the column (i.e., the extension direction of the first axis) relative to the adjusting seat 80 can be limited. Therefore, when the adjusting seat 80 needs to rotate relative to the casing, the orientation of the connecting plate 10 and the connecting rod assembly will not be affected by the movement of the adjusting seat 80, and the operation of re-adjusting the orientation of the connecting rod assembly due to adjusting the adjusting seat 80 can be avoided.

[0065] In some embodiments, the connection length between the connection portion 82 and the support base 20 is adjustable.

[0066] By setting the connection length between the connecting portion 82 and the support seat 20 to be adjustable, the overall height of the fuel manifold nozzle tooling of the present invention can be adjusted, thereby further improving the applicability of the fuel manifold nozzle tooling of the present invention.

[0067] like Figure 2 As shown, the connecting portion 82 and the support seat 20 can be connected by a thread. The connecting portion 82 is provided with an external thread, and the support seat 20 is provided with an internal thread hole. The overall height of the fuel main pipe nozzle tooling can be adjusted by adjusting the length of the threaded connection between the connecting portion 82 and the support seat 20.

[0068] like Figure 1 and Figure 2As shown, in some embodiments, the adjustment seat 80 also includes an external hexagonal structure connected between the limiting portion 81 and the connecting portion 82, so as to facilitate the use of tools such as a hexagonal wrench to adjust the length of the threaded connection between the connecting portion 82 and the support seat 20.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, the support base 20 includes a flat plate-like structure, and a plurality of connecting holes are provided on the flat plate-like structure so as to connect the support base 20 to the receiver through the connecting holes.

Among them, the support seat 20 and the adjustment seat 80, and the connecting plate 10 and the first connecting rod 30 are all threadedly connected, and the connection lengths of the above two threaded connections are adjustable; the first connecting rod 30 and the second connecting rod 40, the second connecting rod 40 and the third connecting rod 60, and the third connecting rod 60 and the fourth connecting rod 70 are respectively connected by the first joint structure 50, the second joint structure 90, and the third joint structure 100 to realize ball joint connection; the fourth connecting rod 70 includes a spherical structure for connecting with the fuel manifold nozzle joint.

[0072] like Figure 1 to Figure 3 As shown, the first joint structure 50, the second joint structure 90 and the third joint structure 100 are all damping ball joint structures. The first joint structure 50 includes a first outer ring 51 and a first inner ring 52 that can rotate relative to each other. The second joint structure 90 includes a second outer ring 91 and a second inner ring 92 that can rotate relative to each other. The third joint structure 100 includes a third outer ring 110 and a third inner ring 120 that can rotate relative to each other. The second connecting rod 40 includes a first limiting structure 43. The third connecting rod 60 includes a second limiting structure 61. The fourth connecting rod 70 includes a third limiting structure 71. Between the first link 30 and the second link 40, the first outer ring 51 is connected to the first link 30, and the first inner ring 52 is connected to the first limiting structure 43; between the second link 40 and the third link 60, the second outer ring 91 is connected to the second link 40, and the second inner ring 92 is connected to the second limiting structure 61; between the third link 60 and the fourth link 70, the third outer ring 110 is connected to the third link 60, and the third inner ring 120 is connected to the third limiting structure 71.

[0073] like Figure 3As shown, the second connecting rod 40 includes an outer rod 41 and an inner rod 42, and the outer rod 41 and the inner rod 42 are connected by internal and external threads, and the second outer ring 91 of the second joint structure 90 and the outer rod 41 are an integrally formed structure. Among them, the outer rod 41 is also provided with an external hexagonal structure, so that the threaded connection length between the outer rod 41 and the inner rod 42 can be adjusted by using a tool such as a hexagonal wrench.

[0074] like Figure 2 As shown, the support seat 20 is provided with four connecting holes for connecting to the receiver and an internal threaded hole for connecting to the adjustment seat 80; the adjustment seat 80 includes a limiting portion 81, a connecting portion 82 and an external hexagonal structure connected between the limiting portion 81 and the connecting portion 82, so as to cooperate with tools such as a hexagonal wrench, and the connecting plate 10 is rotatably sleeved on the outer periphery of the limiting portion 81, and the connecting portion 82 is provided with an external thread for matching with the internal threaded hole of the support seat 20; the connecting plate 10 is provided with an internal threaded hole, and the first connecting rod 30 is provided with an external thread matching with the internal threaded hole of the connecting plate 10, and the first connecting rod 30 is also provided with an external hexagonal structure, so as to facilitate the use of tools such as a hexagonal wrench to adjust the threaded connection length between the first connecting rod 30 and the connecting plate 10.

[0075] The specific steps of positioning the fuel manifold before assembly based on the above-mentioned embodiment of the fuel manifold nozzle tooling are as follows:

[0076] (1) Select an appropriate number of tooling: Select a number of tooling equal to the number of fuel nozzles in the combustion chamber.

[0077] (2) Installing the fuel manifold nozzle tooling: Based on the position of the fuel nozzle in the outer casing of the combustion chamber, several support seats 20 of the fuel manifold nozzle tooling are positioned and installed around the circumference of the casing, and then the rest of the fuel manifold nozzle tooling is installed as a whole on the support seat 20.

[0078] (3) Adjusting the height of the fuel manifold nozzle fixture: The height of the fuel manifold nozzle fixture is adjusted in three stages according to the actual fuel nozzle height. The first stage of adjustment is to adjust the spatial height of the fourth connecting rod 70 by rotating the third connecting rod 60; the second stage of adjustment is to adjust the spatial height of the second connecting rod 40 by rotating the first connecting rod 30, and the second stage of adjustment is to adjust the length of the threaded connection between the outer rod 41 and the inner rod 42 by rotating the outer rod 41 of the second connecting rod 40, thereby adjusting the length of the second connecting rod 40; the third stage of adjustment is to adjust the height of the connecting plate 10 and the connecting rod assembly relative to the support seat 20 by rotating the adjustment seat 80; the above operations need to be performed multiple times until the spherical structure of the fourth connecting rod 70 is adjusted to the accurate spatial height position of the fuel nozzle joint.

[0079] (4) Adjusting the angle of the fuel manifold nozzle fixture: adjusting the threaded fitting length of the first connecting rod 30 and the connecting plate 10 to adjust the position of the connecting rod assembly in the extension direction of the second axis, rotating the second connecting rod 40 to position it at a certain spatial angle, and rotating the fourth connecting rod 70 to position it at a certain spatial angle; the above operation needs to be performed multiple times until the spherical structure of the fourth connecting rod 70 is adjusted to the accurate spatial angle position of the fuel nozzle joint.

[0080] Finally, the height and angle of the fuel manifold nozzle fixtures at other positions around the casing are adjusted in turn according to the methods described in the above steps (3) and (4), so that the fuel manifold can be further positioned and assembled.

[0081] Through the description of multiple embodiments of the fuel manifold nozzle fixture of the present invention, it can be seen that the fuel manifold nozzle fixture of the present invention has at least the following advantages:

[0082] 1. Strong versatility. The connecting plate and the connecting rod assembly, the support seat and the connecting plate are arranged to be relatively rotatable, so that the fuel manifold nozzle tooling of the present invention can be adjusted in various directions relative to the casing to connect with the fuel manifold nozzle joints at different positions, thereby meeting the assembly requirements of fuel manifolds with different structures.

[0083] 2. Strong adjustability. The fuel manifold nozzle tooling of the present invention has many degrees of freedom in adjustment, and the tooling height and angle can be adjusted in multiple levels according to actual assembly requirements, realizing the spatial position adjustment of the tooling as a whole, and having strong adjustability.

[0084] 3. Low cost. Since all parts of the fuel manifold nozzle tooling of the present invention are detachably connected, it can be matched with fuel manifolds of different structures by replacing some components, or only the damaged parts can be replaced when some components are damaged. Compared with the one-to-one matching type of fuel manifold assembly tooling and fuel manifold configuration in the related art, the present invention greatly saves manpower and material costs and reduces the production and manufacturing costs of the tooling and the fuel manifold.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that without departing from the principles of the present invention, the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the present invention.
