Description

TECHNICAL FIELD

[0001] The present application belongs to the field of aircraft manufacturing, and particularly relates to a flexible profile inspection tool for a wall plate and a method for using the same. BACKGROUND

[0002] The shot forming process is a key link in the development of a metal wing wall plate, and the development cycle of the process greatly determines the development cycle of the wall plate and even the whole aircraft. The profile inspection of the wall plate is an important basis for judging whether the profile of the wall plate is qualified after the shot forming, and its importance is self-evident. At present, the profile inspection of the wall plate depends on a unique profile inspection tool designed and manufactured according to the profile of the wall plate. The structure of the profile inspection tool is that a sample plate seat is welded on a tool body, a reverse-cut profile inspection sample plate is installed on the sample plate seat, and the reverse-cut profile inspection sample plate is fixedly arranged on each rib position of the wall plate along the chord direction. When the profile inspection is performed, the outer surface of the wall plate is tightly attached to the sample plate, and whether the profile of the wall plate is qualified is checked by checking whether the gap between the outer surface of each rib position of the wall plate and the reverse-cut profile inspection sample plate is less than or equal to 0.5 mm.

[0003] In recent years, the complexity, development quantity and development difficulty of the wall plate are increasing, which brings the following problems to the profile inspection of the wall plate: (1) When multiple wall plates are developed at the same time, a corresponding profile inspection tool needs to be manufactured for each wall plate, and the tool manufacturing process takes a long time, which slows down the development progress; (2) The structure of the wall plate needs to be adjusted multiple times during the development stage, which causes the profile inspection tool of the wall plate to be unable to follow the adjustment in time; (3) The sample plate inspection of the local profile cannot be timely increased in the local key area according to the assembly needs.

[0004] (4) The lateral bending phenomenon of the wall plate after the shot forming is more and more obvious, and the lateral bending seriously affects the assembly. At present, the lateral profile of the wall plate is measured by using a laser, and the degree of lateral bending is calculated.

DETAILED DESCRIPTION

[0020] Example 1 The flexible profile inspection tool places the inner surface of the wallboard downward on the inspection tool, so that the inner surface of the wallboard contacts the inspection template (8) of the inspection tool, and the clearance between the inspection template (8) and the inner surface of the wallboard is detected to determine whether the profile of the wallboard is qualified. The flexible profile inspection tool is mainly used to support the profile inspection template (8) in the area of the wallboard to be inspected, so as to perform profile inspection in the area. Because the tool has a certain flexibility and the position of the template (8) is not corrected by laser point calibration for specific wallboards, the tool cannot be used for formal profile inspection of the wallboard, but only for profile inspection of the wallboard test piece after shot peening forming during the development of the wallboard. Since the formal wallboard still needs to be shot peened after forming, the processing capacity of the shot peening is sufficient to compensate for the errors caused by design, manufacturing, operation and other factors of the tool, so the tool is sufficient to verify the ability of the shot peening process to process the formal wallboard.

[0021] As shown in Figure 1 , the present application provides a flexible profile inspection tool for wallboard, which comprises a tool body (1), a reverse T-shaped groove (2), a template slide block positioning hole (3), a template slide block fixing pin (4), a template slide block (5), a template seat (6), a template fixing assembly (7), a template (8), a wallboard stop block assembly (9), and a wing root positioning assembly (10). Wherein: The tool body (1) comprises a plurality of inspection units. The inspection unit comprises a template slide block (5), a template slide block fixing pin (4), a template seat (6), a template fixing assembly (7), a template (8), a wallboard stop block assembly (9), and a wing root positioning assembly (10). The tool body (1) has a reverse T-shaped groove (2), and the template slide block (5) has a through groove matching the reverse T-shaped groove (2), so that the inspection unit can slide on the tool body (1). The tool body (1) is uniformly provided with template slide block positioning holes (3) for inserting template slide block fixing pins (4) to fix the inspection unit at the desired position. The template seat (6) is connected with the template (8) through the template fixing assembly (7). The template (8) is provided with the wallboard stop block assembly (9), which comprises a stop block (91), a clamping stop block (92), and a nut (93). The template (8) at the wing root is provided with two wing root positioning assemblies (10), which comprise a wing root positioning block (101) and a positioning block fixing bolt (102), Specifically, the template seat (6) has a polygonal column, and the template slide block (5) has a polygonal columnar groove matching the polygonal column, as shown in Figure 2 The polygonal column and the polygonal columnar groove make the template seat (6) and the template slide block (5) form a form lock.

[0022] Specifically, the template seat (6) can be locked with the template slider (5) every fixed angle. The template seat (6) and the template slider (5) are locked and do not rotate relative to each other, and only one relative movement degree is provided to facilitate disassembly.

[0023] Specifically, the fixed angle is equal to 360° divided by the number of polygonal edges of the polygonal columnar groove.

[0024] Specifically, the template fixing assembly (7) includes a bolt with a handle and a matching tightening nut, which facilitates the installation and disassembly of the template (8).

[0025] Specifically, the wall plate stopper assembly (9) is fixed on the theoretical edge line position of the rear beam of the template (8) by tightening the nut (93) to make the clamping stopper (92) and the stopper (91) clamp the template (8) together, as shown in Figure 3 .

[0026] Specifically, the wing root positioning assembly (10) is fixed on the template (8) by using the positioning block fixing bolt (102), and the wing root positioning block (101) has a stepped surface, the surface in contact with the template (8) is thicker, and the surface in contact with the wall plate end is thinner, so that the wall plate end can be stably placed on the wing root template (8), as shown in Figure 4 .

[0027] Specifically, the adjustment degree of the position of the template (8) is controlled by the arrangement density of the template slider positioning hole (3), and the angle adjustment degree of the template (8) is controlled by the number of polygonal edges of the polygonal column and the polygonal columnar groove.

[0028] In summary, the flexible profile inspection tool for wallboards provided by the present application has a certain flexibility and can be used for most wallboard profile inspection, so as to adapt to the change of wallboard profile, realize rapid measurement of wallboard profile, shorten the development cycle, and reduce the development cost.

[0029] Embodiment two The present application provides a method for using a flexible profile inspection tool for wallboards, comprising the following steps: Step 1: manufacturing the size of the flexible profile inspection tool.

[0030] Specifically, the length of the tool body (1) is designed and manufactured according to the length of the longest wallboard to be developed, the specific size of each part of the tool is designed according to the weight of the wallboard to ensure the strength of the tool, and enough inspection units are designed and manufactured according to the length of the wallboard, the number of ribs, and the profile inspection requirements.

[0031] Step 2: design and manufacture the template (8) according to the profile of the wallboard to be developed.

[0032] Specifically, step 2 comprises: Step 21: planning the position of the template (8). The template (8) needs to be arranged at each rib position of the wallboard to be inspected, at the position where the curvature of the wallboard changes sharply, at the position where the curvature of the wallboard is large, at the wing root of the wallboard, and at the wing tip of the wallboard.

[0033] Step 22: planning the angle of the template (8). The template (8) is arranged along the rib line at each rib position, is arranged along the direction of the greatest curvature change gradient at the position where the curvature changes sharply, and is arranged along the edge line direction of the wing root and wing tip at the wing root and wing tip of the wallboard.

[0034] It should be noted that if there are other areas, the template (8) can be added according to the inspection requirements. When designing and manufacturing the template (8), the wallboard needs to be rotated by a certain angle, so that the rear beam edge of the wallboard is closer to the ground and the front beam edge is farther away from the ground. After the tooling is installed, the rear beam end of the template (8) is low and the front beam end is high, and the wallboard stop block assembly (9) is used to prevent the wallboard from falling.

[0035] Step 23: determining the position of the template (8). According to the position where the template (8) needs to be arranged, the position where the template slide (5) can be fixed is selected as the actual arrangement position of the template (8).

[0036] Step 24: determining the angle of the template (8). The specified angle of the template (8) that can be adjusted is selected as the actual arrangement angle of the template (8).

[0037] It should be noted that when manufacturing the template (8), the position of the tooling template (8) is controlled by the position of the inspection unit, and the position of the inspection unit is controlled by the position of the template slide (5). Therefore, the position where the template slide (5) can be fixed must be selected as the actual arrangement position of the template (8) according to the position where the template (8) needs to be arranged. Since the angle adjustment scale of the template (8) is controlled by the number of polygonal edges of the polygonal column and the polygonal columnar groove, the specified angle of the template (8) that can be adjusted must be selected as the actual arrangement angle of the template (8).

[0038] Step 25: determining the shape of the template (8) and manufacturing the template (8). According to the position and angle of the template (8), the inverse excircle curve of the wallboard is extracted as the shape of the template (8). The template (8) is manufactured, and the theoretical edge line of the wallboard is marked on the template (8).

[0039] Step 3: assembling the flexible shape inspection tooling, using the template (8) to inspect the shape of the wallboard, and obtaining the shape inspection result of the wallboard.

[0040] Specifically, step 3 comprises: Step 31: install the template (8). One template (8) corresponds to one inspection unit, and the required inspection unit is installed on the tool body (1) according to the actual arrangement position and angle of the template (8), and the template (8) is installed at the corresponding position.

[0041] Step 32: install the wallboard block assembly (9). Install the wallboard block assembly (9) close to the theoretical edge line of the wallboard of the template (8), and install the wallboard block assembly (9) on the wing root template (8).

[0042] Step 33: place the wallboard on the flexible contour inspection tool. After shot peening forming of the wallboard, place the wallboard on the contour inspection tool, first make the end of the wallboard fit with the two wing root positioning assemblies (10) of the tool, then make the wallboard fit with the wallboard block assembly (9) of the tool, and ensure that the wallboard fits with at least one wallboard block assembly (9) of the template (8), then the wallboard is placed.

[0043] Step 34: record the inspection data. Use the tool to inspect the gap values of the front beam, rear beam and middle part of each template (8) and the inner surface of the wallboard, and record them. Find the rib position where the edge of the wallboard is close to the wallboard block assembly (9), and record the gap between this rib position and the wallboard block (91) as 0. Record the gap between the edge of the remaining rib position and the wallboard block assembly (9).

[0044] Step 4: analyze the contour inspection result of the wallboard.

[0045] Specifically, step 4 includes: Step 41: obtain the curvature contour state of the wallboard according to the wallboard contour inspection data.

[0046] The principle of wallboard curvature contour analysis is: compare the gap values of the local adjacent templates (8) in the middle part to judge the local spanwise curvature contour, 1) if it is a saddle-shaped wallboard, the gap values of the two side templates (8) are greater than the gap value of the middle template (8), then the local spanwise curvature contour is insufficient; if the gap values of the two side templates (8) are less than the gap value of the middle template (8), then the local spanwise curvature contour is excessive. 2) If it is a double convex wallboard, the gap values of the two side templates (8) are greater than the gap value of the middle template (8), then the local spanwise curvature contour is excessive; if the gap values of the two side templates (8) are less than the gap value of the middle template (8), then the local spanwise curvature contour is insufficient.

[0047] Compare the gap values of the same template (8) and the front and rear beams of the wallboard with the gap value of the middle part of the template (8) to judge the local chordwise curvature contour, if the gap values of the front and rear beams are greater than the gap value of the middle template (8), then the local chordwise curvature contour is excessive; if the gap values of the front and rear beams are less than the gap value of the middle template (8), then the local chordwise curvature contour is insufficient.

[0048] Step 42: obtain the lateral bending value of the wallboard according to the wallboard contour inspection data.

[0049] The principle of analyzing the lateral bending profile of the panel is as follows: find the rib position where the panel edge is close to the stop block (91), and record the gap between this rib position and the stop block (91) as 0. Record the gaps between the panel edges of the remaining rib positions and the stop block (91). Draw a broken line graph with the rib positions as the horizontal coordinates and the gaps as the vertical coordinates. Connect the gap value points of the wing root stop block (91) and the wing tip stop block (91) in the broken line graph, and a line segment can be obtained. Draw a perpendicular line through the maximum or minimum gap value point, and the length of the perpendicular line segment between the line segment and the maximum or minimum gap value point is the lateral bending value of the panel. If there is a minimum value point, the lateral bending is in the direction of the rear spar. If there is a maximum value point, the lateral bending is in the direction of the front spar.

[0050] It should be noted that if the panel profile design is changed or new assembly inspection requirements are added, the arrangement position and number of the inspection units can be adjusted, the arrangement angle of each template (8) can be adjusted, or a new template (8) can be designed and manufactured to reassemble the inspection tooling for subsequent panel profile inspection. If the development cycle is tight and multiple panels need to be developed in parallel, multiple sets of templates (8) can also be manufactured simultaneously according to the inspection requirements of multiple panels, and the corresponding profile inspection tooling can be assembled at any time according to the panel to be inspected.

[0051] Example Three As shown in Figure 5 , assume that a certain panel to be developed (11) has a saddle shape with a length of 5.6m. The flexible profile inspection tooling for a panel and its use method are specifically described based on this panel.

[0052] Step 1: Design and manufacture a certain flexible profile inspection tooling (12).

[0053] The length of the longest panel to be developed in this batch is 13m, and a margin is reserved for the tooling at both ends. Therefore, the length of the flexible profile inspection tooling body (1) is designed to be 13.5m. The number of rib positions is about 20, and the complexity of the panel curvature is moderate. Therefore, 26 inspection units are designed and manufactured according to 1.3 times the number of rib positions. A template slide block positioning hole (3) is provided every 100mm on the tooling body (1), and an octagonal column is provided on the template seat (6). The specific dimensions of each part of the tooling are designed according to the weight of the panel to ensure the strength of the tooling.

[0054] Step 2: Determine the position of the profile to be inspected according to the profile of the panel to be developed, and design and manufacture the template (8).

[0055] The number of rib positions of a certain panel to be developed (11) is 6. The template (8) is arranged along the rib line at each rib position of the panel, and the template (8) is arranged along the wing root and wing tip edge line at the wing root and wing tip. According to the curvature analysis of the panel profile, it can be known that the profile curvature between rib 1 and rib 2 changes dramatically, and the maximum curvature gradient direction is in the direction from the 1 rib front spar position to the 2 rib rear spar position, as shown in Figure 5Therefore, an additional template (8) needs to be arranged between 1-rib and 2-rib in this direction.

[0056] According to the position of the template (8) to be arranged, the position where the template slider (5) can be fixed is selected as the actual arrangement position of each template (8), as shown in the figure. Figure 5 The direction of the maximum curvature gradient between 1-rib and 2-rib is the direction of the template (8) rotating counterclockwise by 36 degrees. Since the polygonal column on the template base (6) is octagonal, the adjustment angle is 45°. Therefore, the actual arrangement angle of the template (8) is counterclockwise rotation by 45°. When designing the template (8), the wallboard needs to be rotated by 10° from the horizontal direction, so that the rear beam edge of the wallboard is closer to the ground and the front beam edge is farther away from the ground. The wallboard stopper assembly (9) is used to prevent the wallboard from falling. The shape of the template (8) is designed according to the actual arrangement position and angle of the template (8), and the template (8) is manufactured. The theoretical edge line of the wallboard is marked on the template (8).

[0057] Step 3: Assemble a certain flexible shape inspection tool (12) and perform shape inspection.

[0058] One template (8) corresponds to one inspection unit. According to the actual arrangement position and angle of the template (8), the required inspection units are installed on the tool body (1). The wallboard stopper assembly (9) is installed outside the theoretical edge line of the wallboard rear beam of the template (8). The wallboard stopper assembly (9) is installed on the wing root template (8). The assembly of a certain flexible shape inspection tool (12) is completed. After the wallboard is shot peening, the wallboard is placed on the shape inspection tool. First, the end of the wallboard is attached to the two wing root positioning assemblies (10) of the tool, and then the wallboard is attached to the wallboard stopper assembly (9) of each template (8) of the tool. Finally, the wallboard is attached to the 3-rib stopper assembly, and the wallboard is placed. The gap values of the front beam, rear beam, and middle part of the wallboard inner surface are recorded using this tool. The gap of the 3-rib stopper (91) is recorded as 0. The gap of the remaining rib stopper (91) is recorded.

[0059]

[0060] Step 4: Analysis of wallboard shape inspection results Wallboard spanwise curvature shape analysis: The gap between the wallboard 2-rib, 3-rib, 4-rib, and the middle part of the template (8) is 0mm, and the gap between the adjacent templates (8) gradually increases. The wallboard is a saddle-shaped wallboard, and it can be known that the wallboard spanwise curvature shape is insufficient.

[0061] The gap values between the wallboard and the wing root, 1-rib, additional template (8), 2-rib, 3-rib, 4-rib, front and rear beams are all greater than the middle template (8) gap value, indicating that the chordwise curvature shape of the above rib positions is excessive. The gap values between the wallboard and 5-rib, 6-rib, and wing tip front and rear beams are all less than the middle template (8) gap value, indicating that the chordwise curvature shape of the above rib positions is insufficient.

[0062] A broken line graph is drawn with the rib position as the horizontal coordinate and the gap as the vertical coordinate, as shown in Figure 6 . In Figure 6 , the wing root block (91) gap value point and the wing tip block (91) gap value point are connected, and a line segment is obtained. A perpendicular line is drawn through the 3-rib block (91) gap value point, and the length of the perpendicular line segment between the line segment and the 3-rib block (91) gap value point is 0.78 mm, as shown in Figure 7 . It can be seen that the lateral bending value of the wall plate is 0.78 mm, and the lateral bending is in the direction of the rear beam.
