[0002] The low-pressure turbine rotor and stator unit of an aircraft engine consists of two parts: a rotor and a stator. The assembly mode is vertical. The rotor and stator are sealed with a honeycomb grate sealing structure. To ensure good sealing, the radial clearance between the honeycomb on the stator and the grate on the rotor is small, with the minimum being only 0.2mm. During the installation of the rotor and stator, the grate and honeycomb are invisible. Without good centering guidance, the stator and rotor will often scrape during installation, causing damage to the sealing structure and subsequent degradation of engine performance. Because the mounting holes for the bolts on the casing are through holes, it is difficult to directly fix the guide pins. Summary of the Invention

[0062] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0063] like Figure 1-Figure 4 As shown, this embodiment is a guide device 100, which is used for assembling a component 90 of an aircraft engine. The guide device 100 includes: a guide pin 11, an upper support seat 20, a lower support seat 40 and an adjustment assembly 30; the guide pin 11 passes through the flange hole 92 of the first flange 91 of the component 90 and is inserted into the top of the upper support seat 20, and the upper side surface of the upper support seat 20 is used to support the lower side surface of the first flange 91; the lower support seat 40 is provided on the upper side surface of the second flange 93 of the component 90, and the adjustment assembly 30 is slidably provided on the upper side surface of the lower support seat 40, and the adjustment assembly 30 acts on the upper support seat 20 and the lower support seat 40, so that the upper support seat 20 and the lower support seat 40 are fixed between the lower side surface of the first flange 91 and the upper side surface of the second flange 93. By using the adjustment assembly 30 to fix the upper support base 20 and the lower support base 40 between the first flange 91 and the second flange 93, a stable support can be provided for the guide pin 11. The guide pin 11 is then connected to the upper support base 20, thereby guiding the assembly of different components 90. The guiding device 100 has a simple structure and is stable and reliable.

[0064] The first flange 91 may be an upper flange of the component 90 , the second flange 93 may be a lower flange of the component 90 , and the guide device 100 is disposed between the upper flange and the lower flange.

[0065] The lower end of the guide pin 11 can be provided with a thread, and the upper support seat 20 is provided with a corresponding insertion hole 24, which can be a threaded hole, and the guide pin 11 and the upper support seat 20 can be connected by a thread. Of course, the guide pin 11 can also be directly inserted into the insertion hole 24 of the upper support seat 20.

[0066] The adjustment assembly 30 includes a first slider 31, a second slider 32, and a tensioning member 33, which are arranged in opposite directions. The upper support seat 20 is disposed between the first slider 31 and the second slider 32. The tensioning member 33 acts on the first slider 31 and the second slider 32 to adjust the distance between the upper support seat 20 and the lower support seat 40. The tensioning member 33 pulls the first slider 31 and the second slider 32, thereby pushing the upper support seat 20 in the middle, thereby stably and reliably fixing the upper support seat 20 and the lower support seat 40 between the first flange 91 and the second flange 93.

[0067] Corresponding sliding slopes 21 are provided between the upper support seat 20 and the first and second sliders 31 and 32, respectively. The tensioning member 33 pulls the first and second sliders 31 and 32 toward each other, and the upper support seat 20 moves away from the lower support seat 40 under the action of the sliding slopes 21. Under the action of the tensioning member 33, the first and second sliders 31 and 32 move toward each other, thereby converting the force of the upper support seat 20 away from the lower support seat 40 through the sliding slopes 21. As a result, the upper support seat 20 and the lower support seat 40 can respectively abut against the first flange 91 and the second flange 93. The guide device 100 is simple to operate and provides stable and reliable results. In other embodiments, the sliding slopes 21 can be replaced by mutually cooperating slide rails or slide grooves, and of course other sliding forms can also be used.

[0068] The included angle between the sliding slope 21 and the axis of the tensioning member 33 may be in the range of 30°-75°, and is preferably one of 45°, 50°, and 60°.

[0069] The first slider 31 has a first threaded hole 311, and the second slider 32 has a second threaded hole 321. The tensioning member 33 includes a screw 330 having a first threaded segment 331 and a second threaded segment 332 corresponding to the first threaded hole 311 and the second threaded hole 321, respectively. Using the screw 330 to pull the first and second sliders 31 and 32 provides a simple structure, easy operation, and a stable and reliable sliding process. In other embodiments, other means of generating tension between the first and second sliders 31 and 32 may be used, such as a spring or a clip.

[0070] In one embodiment, the first threaded hole 311 of the first slider 31 can be provided with a left-handed thread, and the first threaded segment 331 of the screw rod 330 can be arranged corresponding to the first threaded hole 311. The second threaded hole 321 of the second slider 32 can be provided with a right-handed thread, and the second threaded segment 332 of the screw rod 330 can be arranged corresponding to the second threaded hole 321. Thus, when the screw rod 330 is rotated counterclockwise, the first and second sliders 31 and 32 are pushed toward each other by the threads, thereby pushing the upper support seat 20 upward via the sliding slope 21. The upper side surface of the upper support seat 20 then abuts against the lower side surface of the first flange 91, and the lower side surface of the lower support seat 40 abuts against the upper side surface of the second flange 93, tightly confining the guide device 100 between the first and second flanges 91 and 93. Of course, when the screw rod 330 is rotated counterclockwise, the first and second sliders 31 and 32 are pushed away from each other by the threads, and the upper support seat 20 moves downward under the action of gravity, which will not be further described.

[0071] The upper support base 20 is provided with a connecting hole 22, through which the tensioning member 33 is inserted. This prevents the upper support base 20 from accidentally sliding or falling off, thereby improving the safety and reliability of the guide device 100. Preferably, the connecting hole 22 is located at the center of the upper support base 20, and the axis of the connecting hole 22 can intersect the axis of the guide pin 11.

[0072] like Figure 4 As shown, the cross-section of the connecting hole 22 is an oblong hole, with the length of the oblong hole extending along the axis of the guide pin 11. The oblong-shaped connecting hole 22 can better accommodate the tensioning member 33 and avoid hindering the movement of the upper support base 20. In other embodiments, the connecting hole 22 can also have other shapes, such as a rectangular hole, an elliptical hole, etc.

[0073] The axial direction of the guide pin 11 is perpendicular to the axial direction of the tension member 33. Preferably, the axis of the guide pin 11 intersects with the axis of the tension member 33. This can better convert the tension of the tension member 33 into power for the upper support seat 20.

[0074] A guide post 23 is provided at the bottom of the upper support base 20. The axis of the guide post 23 is oriented in the direction from the upper support base 20 away from the lower support base 40. A guide hole 41 is provided on the upper side of the lower support base 40, and the guide post 23 is inserted into the guide hole 41. The guide post 23 guides the movement of the upper support base 20 and facilitates the positioning and assembly of the upper support base 20 relative to the lower support base 40. The axis of the guide post 23 can coincide with the axis of the guide pin 11.

[0075] The upper side of the lower support seat 40 is provided with a slide groove 42, and the adjustment assembly 30 is arranged in the slide groove 42. The slide groove 42 can limit the movement direction of the adjustment assembly 30, can prevent the adjustment assembly 30 from accidentally sliding, and can improve the stability and safety of the adjustment assembly 30 during use.

[0076] The guide device 100 also includes a stop screw 12. Stop holes 34 are provided on the sides of the first and second sliders 31, 32. Stop slots 43 corresponding to the stop holes 34 are provided on the sides of the slideway 42. The length of the stop slots 43 is arranged along the sliding direction of the first slider 31. The stop screw 12 is inserted into the stop hole 34 through the stop slots 43. The stop screw 12, which penetrates the first and second sliders 31, 32, prevents the first and second sliders 31, 32 from detaching from the lower support seat 40, improves the integrity of the guide device 100, facilitates assembly of the guide device 100, and enhances the stability and reliability of the adjustment process.

[0077] As an embodiment, the component 90 may be a stator casing of an aircraft engine. The guide device 100 assembles two different stator casings together. The guide device 100 is briefly described below using the stator casing as an example.

[0078] The guide device 100 is fixed between the upper and lower flange edges of the stator casing, and the guide pin 11 is inserted into the upper support seat 20, thereby achieving the fixation of the guide pin 11 on the engine stator casing, and then guiding the centering assembly of the remaining casings or stators.

[0079] The guide device 100 adopts a split structure, with the upper support seat 20, the lower support seat 40 and the adjustment assembly 30 installed on the upper and lower mounting edges of the receiver. The guide pin 11 then passes through the flange hole 92 on the mounting edge of the receiver and is tightened on the upper support seat 20, so that the guide pin 11 is not affected by the axial distance between the upper and lower mounting edges of the receiver.

[0080] The guiding device 100 utilizes the movement direction conversion principle of the inclined plane mechanism. The sliding inclined planes 21 of the first slider 31 and the second slider 32 fit with the sliding inclined plane 21 of the upper support seat 20, thereby converting the movement of the first slider 31 and the second slider 32 into the movement of the upper support seat 20, thereby realizing the adjustment of the guiding height.

[0081] The guide device 100 utilizes the movement principle of the screw mechanism. The screw 330 is provided with a first thread segment 331 and a second thread segment 332 with opposite rotation directions, and drives the first slider 31 and the second slider 32 to move respectively, so that the first slider 31 and the second slider 32 push the upper support seat 20 upward together.

[0082] A guide post 23 is provided on the lower side of the upper support seat 20 , and the guide post 23 cooperates with the guide hole 41 of the lower support seat 40 to achieve directional lifting of the upper support seat 20 .

[0083] When guiding the assembly of the casing or stator, the guide device 100 can prevent the rotor and stator from scraping against each other, thereby improving assembly safety. The guide device 100 uses a tightening force to achieve fixation between the front and rear mounting edges of the casing, which is simple to operate, has high installation efficiency, and low process costs. The guide device 100 will not wear or deform and can be used for a long time, which can further reduce process costs. The guide device 100 adopts a split design, which avoids the need to install the guide pin 11 between the front and rear mounting edges of the casing. When the space between the front and rear mounting edges of the casing is narrow, the structural design difficulty of the guide device 100 can be reduced.

[0084] The structures and positional relationships of the various components of the guiding device 100 are further explained below.

[0085] The lower support seat 40 is supported on the upper end face of the flange edge on the lower side of the receiver. The lower support seat 40 can be a rectangular block structure. A vertical guide hole 41 is set in the middle of the lower support seat 40. The guide hole 41 is used to insert the guide column 23 of the upper support seat 20. Two vertical rectangular plates are set on the upper end face of the lower support seat 40 to form a slide groove 42. The slide groove 42 serves as a mounting groove for the first slider 31 and the second slider 32, and guides the sliding of the first slider 31 and the second slider 32. Two horizontal limit grooves 43 are set on the outer side surface of the lower support seat 40. The limit groove 43 is specifically a long round head groove. The limit groove 43 is used to install the limit screw 12, so as to limit the first slider 31 and the second slider 32 in the vertical direction.

[0086] The right end surface of the first slider 31 is formed into an inclined sliding surface 21, which mates with the inclined sliding surface 21 of the upper support seat 20, forming an inclined surface fit. A first threaded hole 311 is provided through the center of the first slider 31. The thread of the first threaded hole 311 can be left-handed. The first threaded hole 311 is used to receive the first threaded segment 331 of the screw 330, thereby forming a screw movement mechanism. A limiting hole 34 is provided on the outer side of the first slider 31. The limiting hole 34 can be a threaded hole and is used to receive the limiting screw 12.

[0087] The left end surface of the second slider 32 is formed into an inclined sliding surface 21. This inclined sliding surface 21 mates with the inclined sliding surface 21 of the upper support seat 20, forming an inclined surface-to-angle relationship. A second threaded hole 321 is provided through the center of the second slider 32. The thread of the second threaded hole 321 can be right-handed. The second threaded hole 321 is used to receive the second threaded segment 332 of the screw 330, thereby forming a screw movement mechanism. A stopper hole 34 is provided on the outer side of the second slider 32. This stopper hole 34 is used to receive the stopper screw 12.

[0088] The left and right end surfaces of the upper support seat 20 are symmetrically formed with inclined sliding surfaces 21. The upper end surface of the upper support seat 20 is provided with an insertion hole 24 for the guide pin 11, which can be a threaded hole. The lower end surface of the upper support seat 20 is provided with a guide post 23, which mates with a guide hole 41 in the lower support seat 40 to guide the vertical movement of the upper support seat 20. A connecting hole 22 is provided in the left and right directions of the upper support seat 20. The connecting hole 22 can be a long, rounded slot for passing the screw 330.

[0089] The left side of the screw rod 330 is a first threaded section 331, which may have a left-handed thread. The right side of the screw rod 330 is a second threaded section 332, which may have a right-handed thread. The first and second threaded sections 331 and 332 mate with the first and second threaded holes 311 and 321, respectively. When the screw rod 330 is rotated counterclockwise, the first and second sliders 31 and 32 move inward along the screw rod 330 and toward each other, thereby driving the upper support seat 20 upward, allowing the upper support seat 20 to be tightened against the lower end surface of the flange on the upper side of the receiver. When the screw rod 330 is rotated clockwise, the first and second sliders 31 and 32 slide outward along the screw rod 330 and away from each other, thereby driving the upper support seat 20 downward, allowing the guide device 100 to be disassembled.

[0090] The limiting screw 12 passes through the limiting slot 43 on the side of the lower support seat 40 , and the limiting screw 12 is installed on the first slider 31 and the second slider 32 .

[0091] The guide pin 11 is installed in the insertion hole 24 of the upper support seat 20. The guide pin 11 is used to guide the centering installation of the casing or the stator.

[0092] As an implementation method, you can press Figure 1-Figure 4 The assembly of the guide device 100 and the guide installation of the stator casing are completed.

[0093] like Figure 4 As shown, the first slider 31, the second slider 32, the screw 330, the limit screw 12, the upper support base 20 and the lower support base 40 are assembled. The screw 330 is turned clockwise to move the first slider 31 and the second slider 32 away from each other, and the upper support base 20 moves downward and is then installed between the two flanges of the receiver.

[0094] The screw rod 330 is rotated counterclockwise to move the first slider 31 and the second slider 32 closer to each other, so that the upper support seat 20 moves upward and abuts against the lower side of the flange.

[0095] Continue to rotate the screw 330 counterclockwise so that the upper support seat 20 presses against the lower end surface of the flange of the casing, and the lower side surface of the lower support seat 40 presses against the upper end surface of the flange.

[0096] The guide pin 11 passes through the flange hole 92 of the receiver and is screwed into the insertion hole 24 of the upper support seat 20.

[0097] Install the remaining guide devices 100 according to the above method. Guide the installation of other casings or stators through guide pin 11 subsequently.
