Description

Technical Field

[0001] This invention relates to the field of aerospace manufacturing technology, and in particular to an assembly device for irregularly shaped sliding guide rails and its usage method. Background Technology

[0002] The irregularly shaped sliding guide rail at the aircraft cabin door is a crucial component in controlling the opening and closing of the door. Its function is to ensure the door slides along a predetermined spatial trajectory throughout the opening and closing process, guaranteeing precise operation. The irregularly shaped sliding guide rail has a multi-segmented grooved structure, arranged side-by-side in space, with a curved guide trajectory and bearing a certain load, thus requiring high positional accuracy. Considering the unique shape and large space occupied by the irregularly shaped sliding guide rail, the current assembly method employs multi-point positioning and independent assembly. During assembly, the guide rail positioning device is pre-fixed to a metal frame. The installation position of the guide rail positioning device has been pre-determined on the metal frame through marking and analog signal transmission. The guide rail positioning device is an integral structure. The guide rail is then segmented and fixed to the guide rail positioning device, aligning the guide rail boundaries with the markings on the positioning device, and pressing the positioning surfaces together. The guide rail is then connected to the guide rail support with bolts. Finally, the clamping device is released, completing the assembly. This assembly method uses integral positioning, eliminating intermediate processes, requiring no auxiliary equipment, simplifying operation, and minimizing absolute assembly error. However, because it is assembled separately from the aircraft fuselage, it requires additional space and introduces relative errors that need to be coordinated with the aircraft fuselage. This leads to inconsistencies in the assembly results of multiple aircraft, making it unsuitable for mass production. For a long time, the inherent structural differences and unique characteristics of aircraft door sliding rails have resulted in significant variations in assembly results each time, which are difficult to measure. These shortcomings are increasingly failing to meet the demands of modern aircraft manufacturing assembly. Existing assembly methods have the following drawbacks: 1. They require repeated adjustments, are time-consuming, and require multiple people to complete; 2. Deviations introduced by machining errors in the positioning device amplify assembly errors, adversely affecting the assembly results; 3. Repeated alignment processes can easily damage finished parts, resulting in waste; 4. Under external interference, the consistency of the assembled sliding rails for each aircraft is poor, failing to meet the requirements for later quality checks and troubleshooting. Furthermore, the inability to quantify assembly errors poses certain hidden dangers. Given these reasons, the need for a precise, efficient, and simple assembly method is becoming increasingly urgent. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an assembly device for irregularly shaped sliding guide rails to solve the technical problems of inconvenience and incompatibility caused by installation based on hatch-door models in the prior art. The assembly device includes: The components include a guide rail positioner 01, a connecting angle bracket 02, a positioning base 07, and a clamping device 03. According to the preset installation position, each of the guide rail positioners 01 is connected to the positioning base 07 through the connecting corner seat 02. The trajectory formed by the coordinates of the preset installation positions of all the guide rail positioners 01 is consistent with the trajectory of the overall irregular sliding guide rail. The preset installation position of the guide rail positioner 01 is determined according to the aircraft fuselage structure. According to the position information of each sliding guide segment on the overall irregular sliding guide, each sliding guide segment is installed on the corresponding guide rail positioner 01, and the sliding guide segment is fixed on the guide rail positioner 01 by the clamping device 03. Adjacent sliding guide segments are spliced ​​together. There is a corresponding relationship between each guide rail positioner 01 and each sliding guide segment.

[0004] This invention also provides a method for using the assembly device for any of the above-mentioned irregular-shaped sliding guide rails, to solve the technical problems of inconvenience and incompatibility caused by installation based on a hatch model in the prior art. The method includes: According to the coordinates of the preset installation positions of each of the guide rail positioners 01, the connection position of each of the guide rail positioners 01 on the positioning base 07 is calibrated by the laser target ball 06 until the connection position is consistent with the coordinates of the preset installation position. Each of the sliding guide rail segments is installed onto its corresponding guide rail positioner 01, and adjacent sliding guide rail segments are spliced ​​together. Drill the connection holes between the sliding guide rail section and the aircraft fuselage structural profile, and install each section of the sliding guide rail on the guide rail bracket.

[0005] Compared with the prior art, the beneficial effects achieved by at least one of the above-mentioned technical solutions adopted in the embodiments of this specification include at least the following: It proposes positioning the installation position of each sliding guide rail segment based on multiple guide rail positioners 01 and positioning base 07, and then installing each sliding guide rail segment on its corresponding guide rail positioner 01, thereby realizing the assembly of the overall irregular sliding guide rail. Since the preset installation position of the guide rail positioner 01 is determined according to the aircraft fuselage structure, the trajectory formed by the coordinates of the preset installation positions of all guide rail positioners is consistent with the aircraft fuselage structure, realizing the method of assembly under the same reference system as the aircraft fuselage, avoiding the errors caused by the original separate assembly; it can ensure the consistency of the assembly results of each group of irregular sliding guide rails, eliminating the variation in assembly results of each aircraft; it reduces the difficulty of operation and improves the assembly efficiency; it increases the success rate, avoids waste of parts, and saves costs.

[0009] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0010] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] In this embodiment of the invention, an assembly device for irregularly shaped sliding guide rails is provided, such as... Figure 1 , Figure 2 , Figure 3 As shown, the assembly device for this irregularly shaped sliding guide rail includes: The components include a guide rail positioner 01, a connecting angle bracket 02, a positioning base 07, and a clamping device 03. According to the preset installation position, each of the guide rail positioners 01 is connected to the positioning base 07 through the connecting corner seat 02. The trajectory formed by the coordinates of the preset installation positions of all the guide rail positioners 01 is consistent with the trajectory of the overall irregular sliding guide rail. The preset installation position of the guide rail positioner 01 is determined according to the aircraft fuselage structure. According to the position information of each sliding guide segment on the overall irregular sliding guide, each sliding guide segment is installed on the corresponding guide locator 01. The sliding guide segment is fixed on the guide locator 01 by clamping device 03 (such as tightening clamping device 03 and nut 04, inserting pin 05), and adjacent sliding guide segments are spliced ​​together. There is a corresponding relationship between each guide locator 01 and each sliding guide segment.

[0012] In specific implementation, there is a corresponding relationship between each of the guide rail positioners 01 and each of the sliding guide rail segments. For example, the guide rail positioners 01 and the sliding guide rail segments can be sequentially numbered and associated with each other through their numbers. For example, the first sliding guide rail segment is associated with the first and second guide rail positioners, the second sliding guide rail segment is associated with the second and third guide rail positioners, and so on.

[0013] In practice, in order to ensure that the assembled irregular sliding rail is compatible with the aircraft fuselage structure, the preset installation position of each rail positioner 01 is determined according to the aircraft fuselage structure. This ensures that the trajectory formed by the coordinates of the preset installation positions of all rail positioners 01 is consistent with the aircraft fuselage structure, thereby ensuring that the assembled irregular sliding rail is consistent with the aircraft fuselage structure.

[0014] In specific implementation, during the initial connection of the guide rail positioners 01, the connection position of each guide rail positioner 01 on the positioning base 07 can be calibrated based on the coordinates of the preset installation positions of each guide rail positioner 01 using the spatial position data of the laser target ball 06, until the connection position matches the coordinates of the preset installation position. After the sliding guide rail section is installed on the guide rail positioner 01, the connecting corner seat 02 can be further finely adjusted using the spatial position data of the laser target ball 06, until the spatial position data of the two laser target balls 06 matches the coordinates of the preset installation positions of the guide rail positioners 01.

[0015] In specific implementation, the assembly device for the above-mentioned irregular sliding guide rail can assemble two irregular sliding guide rails simultaneously. For example, the preset installation position of the guide rail positioner includes a certain irregular sliding guide rail and the specific position coordinates on the certain irregular sliding guide rail. The position information of the sliding guide rail segment also includes the certain irregular sliding guide rail to which it belongs and the position or sequence number on the certain irregular sliding guide rail.

[0016] In specific implementation, since the irregular sliding guide rail has a curved shape, in order to ensure accurate assembly, the following principles are followed when setting the preset installation position of the guide rail positioner 01: First, the guide rail positioner 01 is set at both ends of the overall irregular sliding guide rail; Second, the guide rail positioner 01 is set at a position where the curvature of the irregular sliding guide rail is greater than a preset value, that is, at a position with a larger curvature; Third, the length of the guide rail between two adjacent guide rail positioners 01 is less than or equal to 500 mm; Fourth, the guide rail positioner 01 is set at the splicing point of two adjacent sliding guide rail segments.

[0017] In specific implementation, such as Figure 5 As shown, the guide rail positioner 01 includes: A connector for connecting to the connecting angle seat 02 and for fixing to the clamp 03; The guide rail mounting part is used to install the sliding guide rail section. The shape of the guide rail mounting part is adapted to the guide rail groove of the sliding guide rail section. The guide rail groove of the sliding guide rail section is installed on the guide rail mounting part by the clamping device 03.

[0018] Specifically, the shape of the guide rail mounting part of the guide rail positioner 01 is adapted to the guide rail groove of the sliding guide rail section, and the guide rail groove of the sliding guide rail section is installed on the guide rail mounting part of the guide rail positioner 01, such as... Figure 2 , Figure 3 , Figure 7As shown, ensure that the side curved surface and bottom plane of the sliding guide rail section are in contact with the corresponding surfaces of the guide rail mounting parts of each guide rail locator 01. Fix the sliding guide rail section to the guide rail locator 01 by tightening the clamping device 03 and nut 04. Specifically, the upper boundary (or lower boundary) of the guide rail locator 01 is in contact with the boundary of the irregular sliding guide rail section. The clamping device 03 and nut 04 ensure that the side curved surface of the guide rail locator 01 is tightly fitted with the inner curved surface of the irregular sliding guide rail, ensuring that the guide rail locator 01 does not detach from the irregular sliding guide rail section during the assembly and drilling process.

[0019] Specifically, such as Figure 8 As shown, the sliding guide sections at both ends of the integral irregular sliding guide ensure that the guide boundary fits with the guide positioner boundary, and the boundary surface of the sliding guide section in the middle of the integral irregular sliding guide contacts the positioning pin.

[0020] In practical implementation, to accurately position the guide rail positioner 01 and further ensure assembly accuracy, the assembly device for the aforementioned irregular sliding guide rail also includes: Two laser target balls 06 are respectively set at both ends of the guide rail mounting part; specifically, the guide rail positioner 01 has two holes at both ends, and the laser target balls 06 can be installed in these two holes. After the sliding guide rail segment is installed on the guide rail positioner 01, the spatial position data of the two laser target balls 06 is obtained. When the spatial position data is inconsistent with the coordinates of the preset installation position of the guide rail positioner 01, the connecting corner seat 02 is adjusted until the spatial position data of the two laser target balls 06 is consistent with the coordinates of the preset installation position of the guide rail positioner 01.

[0021] Specifically, the use of the laser target ball 06 positioning method allows for the quantification of assembly errors, resulting in traceability of the results.

[0022] In specific implementation, the connecting corner bracket 02 is adjusted as follows: If the horizontal left-right position of the two laser target balls 06 is inconsistent with the horizontal left-right position of the preset installation position of the guide rail positioner 01, then rotate and / or translate the connecting angle seat 02 left and right to adjust the installation angle between the connecting angle seat 02 and the positioning base 07. The connecting angle seat 02 and the positioning base 07 are connected by bolts. At this time, the bolt holes can be pre-made larger to reserve space for adjusting the installation angle.

[0023] If the vertical position of the two laser target balls 06 is inconsistent with the vertical position of the preset installation position of the guide rail positioner 01, then the connecting corner bracket 02 is moved up and down in the vertical direction. If the horizontal front-to-back position of the two laser target balls 06 is inconsistent with the horizontal front-to-back position of the preset installation position of the guide rail positioner 01, then the thickness of the connecting corner bracket 02 is adjusted, for example, by increasing or decreasing the thickness.

[0024] In practice, after the sliding guide rail section is installed on the guide rail positioner 01, the pre-prepared hatch simulation part is inserted into the irregular sliding guide rail and the sliding is simulated. If the whole process is smooth, the assembly result is as expected. If the sliding is tight in a local area, it means that the assembly tolerance of the positioner in that area is too large. It is necessary to readjust the laser target ball 06 according to the theoretical data and adjust the connecting corner seat 02 until the requirements are met, thereby completing the positioning of the irregular sliding guide rail.

[0025] In practice, to avoid installation errors and reduce assembly efficiency, this embodiment proposes that the non-mounting surfaces of the connecting corner bracket 02 and the guide rail mounting part are provided with boss structures to indicate that the surface without boss structures is the mounting surface.

[0026] In practical implementation, to eliminate the deformation caused by the irregularly shaped sliding guide rail disengaging from the positioning device, a conformal device is introduced, for example, such as... Figure 4 As shown, the assembly device for the aforementioned irregular sliding guide rail also includes: The support structure is spliced ​​on the guide rail positioner 01 on the sliding guide rail section. After the guide rail positioner 01 is disassembled, multiple support structures are installed between the two irregular sliding guide rails.

[0027] Specifically, such as Figure 4 As shown, the support structure includes a support rod with connector components at both ends, which engage with the guide rail grooves. Specifically, multiple support structures can be installed between two irregularly shaped sliding guide rails. The connector components at both ends of the support rod engage with the guide rail grooves to maintain the stable shape of the irregularly shaped sliding guide rails even without the guide rail positioner 01.

[0028] In practice, after all the segmented sliding guide rail sections have been positioned and assembled, the assembled single integral irregular sliding guide rail is as follows: Figure 6 As shown, drill the connection holes between the irregular sliding guide rail and the aircraft fuselage structural profile. After drilling the holes, tighten the connecting screws to complete the assembly of the irregular sliding guide rail and the aircraft fuselage. Finally, remove all guide rail positioners 01 and connecting angle seats 02 without moving them, so that the irregular sliding guide rail is no longer in contact with each positioner, and remove it from the work area.

[0029] In specific implementation, this embodiment provides a method for using the assembly device for any of the above-mentioned irregular-shaped sliding guide rails, including: According to the coordinates of the preset installation positions of each of the guide rail positioners 01, the connection position of each of the guide rail positioners 01 on the positioning base 07 is calibrated by the laser target ball 06 until the connection position is consistent with the coordinates of the preset installation position. Each of the sliding guide rail segments is installed onto its corresponding guide rail positioner 01, and adjacent sliding guide rail segments are spliced ​​together. Drill the connection holes between the sliding guide rail section and the aircraft fuselage structural profile, and install each section of the sliding guide rail on the guide rail bracket.

[0030] Specifically, an example of the method for using the assembly device for the aforementioned irregular sliding guide rail includes the following steps: Step 1: According to the theoretical data of the positioning holes on the guide rail positioner 01, i.e. the coordinates of the preset installation position, use the laser target ball 06 to install each guide rail positioner 01 and connecting corner bracket 02 to the theoretical position, and insert the pin 05 to connect the guide rail positioner 01 and the connecting corner bracket 02. Step 2: Install each sliding guide rail segment onto the positioner 01 from top to bottom, ensuring that the side curved surface and bottom plane of the sliding guide rail segment are in contact with the corresponding surface of each guide rail positioner 01. For the irregular sliding guide rail segments at both ends, ensure that the guide rail boundary is in contact with the positioner boundary, and for the irregular sliding guide rail segment in the middle, the boundary surface is in contact with the positioning pin. Step 3: After the irregular sliding guide section is installed in place, tighten the clamp 03 and nut 04 to ensure that the irregular sliding guide section fits tightly with each guide rail positioner 01, without any looseness or gaps. Figure 7 , Figure 8 ; Step 4: Install the hatch simulation piece into the guide rail groove and simulate the hatch sliding. After confirming that the sliding is smooth and unobstructed, remove the hatch simulation piece; if the sliding is tight, repeat step 1. Step 5: Drill the connection holes between the irregular sliding guide rail and the aircraft fuselage structural profile, install each section of the irregular sliding guide rail on the guide rail bracket, and tighten the connecting screws; Step 6: After installation, loosen the clamp 03, nut 04 and pin 05, remove each guide rail positioner 01, exit the assembly area, install the conformal support rod, and complete the assembly.

[0031] The embodiments of this invention achieve the following technical effects: They propose a method for locating the installation positions of each sliding guide rail segment based on multiple guide rail locators 01 and a positioning base 07, thereby installing each sliding guide rail segment onto its corresponding guide rail locator 01. This enables the assembly of the overall irregular sliding guide rail, achieving assembly under the same reference system as the aircraft fuselage, avoiding errors caused by the original separate assembly method; ensuring the consistency of the assembly results for each group of irregular sliding guide rails, eliminating fluctuations in the assembly results for each aircraft; reducing operational difficulty and improving assembly efficiency; increasing the success rate; avoiding waste of parts; and saving costs.

For those skilled in the art, various modifications and variations can be made to the embodiments of the present invention.
