Description

Technical Field

[0001] The invention belongs to the technical field of composite material assembly tooling and relates to an assembly tooling for composite material sleeve beams. Background Art

[0002] The composite rudder box section is generally connected to the aircraft body structure through a metal hinge arm. There are two main ways to assemble the metal hinge arm and the composite beam. One is to assemble the metal hinge arm and the composite beam in series, that is, the composite beam is located on both sides of the metal hinge arm, and the number of composite beams is generally 2. The other is to assemble the metal hinge arm with a single composite beam or a composite sleeve beam (formed by multiple secondary parts-composite beams). Regardless of the method, the metal hinge arm is bolted to the net size surface of the composite beam, such as the edge strip surface and the web surface, to ensure that the relative position of the metal hinge arm and the composite beam remains fixed. During the secondary co-bonding autoclave forming process of the composite rudder box section, if the composite beam moves or deforms, the corresponding metal hinge arm position deviates from the theoretical position, that is, the axial position of the metal hinge arm deviates from the theoretical position. When the composite rudder box section is transferred to the downstream assembly workshop, the metal hinge arm cannot be connected to the aircraft body structure when it is docked. Since the metal hinge arm has been assembled and connected with the composite beam bolts, the assembly position of the metal hinge arm cannot be adjusted, which will seriously lead to the scrapping of the composite rudder box section.

[0003] At present, conventional assembly tools only have the function of assembly. Taking the assembly scheme of composite material sleeve beam as an example, conventional assembly tools are designed and assembled according to the theoretical position of composite material sleeve beam, such as designing the positioning parts of assembly tools according to the theoretical position of the two side end faces of composite material sleeve beam, and completing the assembly of the theoretical size of composite material sleeve beam based on the positioning parts. However, the curing and molding process of composite materials is an extremely complex coupling process of time, temperature and pressure. Taking composite material sleeve beam as an example, during the secondary co-bonding molding process of composite material rudder box section in autoclave, the composite material sleeve beam will have axial dimension expansion or contraction, that is, the axial dimension of composite material sleeve beam will change during the secondary co-bonding molding process in autoclave, which requires technicians to make corrections according to the change in the axial dimension of composite material sleeve beam, that is, process requirements. The corresponding assembly tool should have the ability to assemble various axial dimensions of composite material sleeve beam, and the assembly tool designed with theoretical assembly dimensions obviously cannot meet the process requirements. At present, conventional assembly tools only have the function of assembly, and cannot accurately and effectively control the axial dimension of composite material sleeve beam based on process requirements.

[0004] In view of the above problems, the present invention takes the assembly of composite material sleeve beams as the research object, and creatively proposes an assembly tool for composite material sleeve beams. The metal joint of the assembly tool replaces the metal hinge structure commonly used in the beam component structure. The metal joint has functions such as assembly and surface compensation, and can realize the assembly requirements based on the downstream assembly reference transmission. The assembly tool has the ability to assemble a plurality of secondary parts-composite beams to form a composite material sleeve beam. The axial dimension of the assembled composite material sleeve beam has a large variation range relative to the theoretical axial dimension: -5-5mm, and the assembly accuracy is 0.01mm. Summary of the invention

[0005] The purpose of this patent is to invent an assembly tool for composite material sleeve beams. The designed metal joints have functions such as assembly and surface compensation, and can realize assembly requirements based on downstream assembly reference transmission; multiple secondary parts-composite beams can be sleeved to form composite material sleeve beams, and the assembly of composite material sleeve beams with various axial dimension changes can be flexibly realized without disassembling and installing tooling accessories, thereby greatly shortening the development cycle of composite material sleeve beams.

[0006] The technical solution of the present invention is as follows:

[0007] The assembly tool of the composite material sleeve beam comprises a metal joint part, an assembly tool positioning part and a sleeve assembly part.

[0008] The overall structure of the assembly tooling is as follows Figure 3 , Figure 4 As shown, it includes a metal joint part, a drilling bushing, a working surface on the edge strip side, a working surface on the web side, a detachable drilling jig, high-precision bolts, nuts, a platform, a column, a tightener support, a connecting assembly, a tightener, a lateral tightener, a connecting piece, a support, a drilling jig back plate, a fixing sleeve, an edge strip profile clamp, an L-shaped support, an adjustable end of the beam end face, an end face action end, a dial indicator, a slotted screw rod, a handle nut, a T-key, a sleeve, a raised block, a long positioning pin, a table seat, a fixed end of the beam end face, an end face action end, a sleeve assembly component, a drilling jig, a connecting piece, a drilling jig back plate, an action table, a placeholder, a support plate, and a tightener sleeve.

[0009] The structural schematic diagram of the metal joint part is shown in FIG2 , which includes a drilling bushing, a working surface on the flange surface side, a working surface on the web surface side, a detachable drilling jig, high-precision bolts, and nuts.

[0010] The metal joint part is to extract the metal hinge arm used for docking with the aircraft body structure from the composite rudder box section. The metal hinge arm is simplified, the central axis position of the intersection of the metal hinge arm is retained and a through hole with a diameter of φ6mm-φ10mm is designed with it as the center. The metal joint part uses Invar steel, and its expansion coefficient is close to that of the composite sleeve beam.

[0011] In order to reduce the deadweight of the metal joint part, remove the driven shaft of the metal hinge arm and unnecessary structures, the metal joint part mainly retains the working surface, reinforcing ribs, positioning pin holes, drilling bushings and other parts. The length of the working surface of the metal joint part along the axial direction of the composite sleeve beam is designed to be 150-200mm. The working surface of the metal joint part located on the web surface side of the composite sleeve beam is offset 2mm to the inner surface of the composite sleeve beam according to the theoretical position, that is, there is a theoretical gap of 2mm between the working surface on the web surface side and the web surface of the composite sleeve beam; the working surface of the metal joint part located on the edge strip surface side of the composite sleeve beam is offset 0.5mm to the inner surface of the composite sleeve beam according to the theoretical position, that is, there is a theoretical gap of 0.5mm between the working surface on the edge strip surface side and the edge strip surface of the composite sleeve beam.

[0012] The working surface on the web surface side and the working surface on the edge strip surface side are offset and manufactured according to the theoretical position on the web surface and edge strip surface of the composite sleeve beam, in order to insert the process compensation gasket between the gap between the working surface on the web surface side and the working surface on the edge strip surface side and the web surface side and edge strip surface side corresponding to the composite sleeve beam. The web surface of the composite sleeve beam is often seen on a plane, and the edge strip surface of the composite sleeve beam is often seen on a curved surface. A number of process compensation gaskets are provided, and the gaskets are used to fill the gap between the working surface on the web surface side and the working surface on the edge strip surface side and the web surface side and edge strip surface side corresponding to the composite sleeve beam. The thickness of a single-layer gasket is 0.1 mm, and the gasket material is stainless steel sheet or copper sheet. Stainless steel sheet or copper sheet has certain flexibility, deformability and low price. Gaskets with different stacking layers are selected according to different filling gaps.

[0013] The working surface on the edge strip side extends 75-100mm relative to the edge of the composite sleeve beam, and the drilling bushing is located on the extension surface of the working surface on the edge strip side. The drilling tool used in conjunction with the drilling bushing is preferably a 90° angular air drill, the purpose of which is to retain a complete process margin at the composite sleeve beam edge strip. The 90° angular air drill performs drilling operations along the drilling bushing from the inside to the outside of the composite sleeve beam edge strip surface.

[0014] Drill bushing holes with high-precision bolts and nuts are used to connect the process allowance area of ​​the composite sleeve beam flange. The high-precision bolts are used to connect the process allowance area of ​​the composite sleeve beam flange. The purpose is to ensure the connection accuracy of the high-precision bolts with the metal joint part and the composite sleeve beam through the length and accuracy of the polished rod. The threaded part of the high-precision bolt is the threaded part with the nut. The connection hole of the composite sleeve beam flange process allowance is drilled by drilling bushings, and the high-precision bolts are connected to the metal joint part and the composite sleeve beam through the connection hole.

[0015] The composite fitting beam is transferred to the downstream assembly, such as the composite rudder box section, which is generally connected to the composite rib. It is necessary to drill holes and place standard parts at the connection position. The metal joint part located at the connection position should have the function of drilling holes and avoid the placed standard parts nail heads. The working surface on the web surface side is designed with through holes and removable drilling jigs. The removable drilling jig is fitted on the through holes. The diameter of the through hole is φa, and the φa size is 2-3mm larger than the diameter of the standard parts nail head. The removable drilling jig is fitted on the through hole. The diameter of the bushing hole of the removable drilling jig depends on the diameter of the standard parts nail rod. The removable drilling jig is used to drill the connection holes of the standard parts. After drilling, the drilling jig is removed. The standard parts are used to connect the assembly connection between the upper beam and the rib in the composite assembly structure frame. The standard parts nail head side is located on the removable drilling jig side.

[0016] The structural diagram of the positioning part of the assembly tool is shown in Figure 3 , Figure 4 The positioning part of the assembly tool is mainly composed of a part for positioning the metal joint and a part for positioning the composite material sleeve beam.

[0017] Among them, the structural schematic diagram of the part of the positioning metal joint is shown in Figure 4 ,Figure 5, mainly consists of components such as platforms and connecting components.

[0018] The platform height is between 1200mm and 1400mm, so that the operator can perform assembly work in a standing position.

[0019] The connection assembly is mainly composed of columns, tensioner supports, tensioners, lateral tensioners, connectors, supports, drilling template back plates, fixing sleeves, tensioner sleeves and other components.

[0020] The column is fixed on the platform by a mechanical connection method combining screws and pins, the support is fixed on the column by a mechanical connection method combining screws and pins, the fixing sleeve is fixed on the column by a mechanical connection method combining screws, and the fixing sleeve has a through-hole structure.

[0021] The main body of the lateral tensioner is a cylinder, with a rotating rod on one side and an action head on the other side. The lateral tensioner passes through the through-hole structure of the fixed sleeve and keeps itself movable in the axial direction. The lateral tensioner and the fixed sleeve are clearance-matched. The lateral tensioner is distributed on both sides of the edge strip outer surface of the composite material sleeve beam. The lateral tensioner acts on the edge strip outer surface of the composite material sleeve beam to ensure that the relative position of the composite material sleeve beam remains fixed.

[0022] The connector is fixed on the support by a positioning pin. Two pin holes are designed on the connector and arranged alternately. The connector can be connected and fixed to the metal joint part by a metal positioning pin through the pin hole.

[0023] The drill template back plate is fixed on the connecting part through a locating pin. The drill template back plate acts on the edge strip surface side of the composite material sleeve beam. The drill template back plate is manufactured by extracting the edge strip shape surface of the composite material sleeve beam and offsetting it outward by 2mm. A through hole is designed at the drilling bushing position of the drill template back plate to ensure that when the drilling bushing passes through the drill bit and drills the composite material sleeve beam, the drilling lead-out end has a support to prevent fiber splitting during the drilling process of the composite material sleeve beam.

[0024] See the schematic diagram of the structure where the tensioner is located. Figure 7 The main body of the tensioner support is a cylindrical design with a through hole design inside. Both ends of the tensioner support have flange structure designs. The flange structure on one side is fixed to the platform by a mechanical connection method combining screws and pins, and the flange structure on the other side is connected and fixed to the tensioner sleeve by a mechanical connection method combining screws and pins. The tensioner sleeve adopts a semicircular annular groove design.

[0025] The handle nut adopts a boss structure design on the outside and a threaded hole design on the inside. The handle nut cooperates with the semicircular annular groove of the tensioner sleeve through its own boss structure. The handle nut and the tensioner sleeve adopt a clearance fit to ensure that the handle nut can rotate around its own axis.

[0026] The handle nut is designed with a threaded hole. The main body of the tensioner is designed with a threaded rod. The tensioner and the handle nut are screwed together. The tensioner is driven to move along its own axis by rotating the handle nut. The outer diameter of the tensioner is accommodated within the through hole size of the tensioner support to ensure the range of motion of the tensioner, so that the tensioner can act on the web surface of the composite sleeve beam to maintain a clamped state, and can stay away from the web surface of the composite sleeve beam to maintain a relaxed state to facilitate the loading and disassembly of the composite sleeve beam.

[0027] The structural diagram of the part where the composite material sleeve beam is positioned is shown in Figure 3 , Figure 4 It is mainly composed of components such as the adjustable end of the beam end, the fixed end of the beam end and the edge strip surface clamping plate.

[0028] The structural schematic diagram of the adjustable end of the beam end face is shown in Figure 6. The adjustable end of the beam end face is mainly composed of the end face action end, a dial indicator, a slotted screw rod, a handle nut, a T-key, a sleeve, a raised block, a positioning long pin, a gauge seat and other components.

[0029] The adjustable end of the beam end face is fixed to the column by a sleeve through a mechanical connection method combining screws and pins.

[0030] The sleeve has a through hole design inside, and one side end of the sleeve adopts a semicircular annular groove design. The top of the sleeve is designed with a raised block, which is fixed to the top of the sleeve by welding. The active surface of the raised block is the active surface of the measuring head of the dial indicator. The position of the active surface of the raised block should ensure that it is perpendicular to the movement direction of the measuring head of the dial indicator. A matching hole that cooperates with the T-key is designed on the top of the sleeve.

[0031] The handle nut adopts a boss structure design on the outside and a threaded hole design on the inside. The handle nut cooperates with the semicircular annular groove of the sleeve through its own boss structure. The handle nut and the sleeve adopt a clearance fit to ensure that the handle nut can rotate around its own axis.

[0032] The outer diameter of the slotted screw is contained within the through hole size of the sleeve to ensure that the slotted screw moves along its own axis, and the sleeve plays a role in supporting the slotted screw. The handle nut is connected to the slotted screw by screw connection.

[0033] One end of the T-key acts on the slotted screw, and the other end acts on the matching hole on the top of the sleeve that cooperates with the T-key. The purpose of the T-key is to ensure that the slotted screw moves along its own axial direction without deflection around the axial direction.

[0034] The action surface of the end action end is manufactured by extracting the end surface shape of one side of the composite material sleeve beam, and the end action end is fixed on the slotted screw rod by connecting with a metal positioning pin.

[0035] The range of the dial gauge is 0-10mm, and the graduation value is 0.01mm. The measuring rod and measuring head of the dial gauge are perpendicular to the action surface of the raised block, and the movement direction of the measuring rod and measuring head of the dial gauge should be parallel to the axis direction of the slotted screw.

[0036] The meter seat has a through hole design, and the meter seat and the slotted screw rod are in an interference fit relationship to ensure that the meter seat is fixed on the slotted screw rod and moves along the axis direction of the slotted screw rod.

[0037] The dial base has a through hole design, and the dial base and the shaft sleeve of the dial indicator are in an interference fit relationship to ensure that the dial indicator is fixed on the dial base, and the measuring rod and the measuring head of the dial indicator are in a relatively free telescopic state.

[0038] The rotation of the handle nut drives the slotted screw rod to move horizontally, and then drives the end face action end to move horizontally. A through hole is designed at the connection between the sleeve and the slotted screw rod, and the diameter of the positioning long pin is consistent with the diameter of the through hole. When the positioning long pin is inserted into the through hole of the sleeve and the slotted screw rod, the theoretical spacing between the action surface of the end face action end and the end surface of one side of the composite material sleeve beam in the axial direction is 5mm, and the measuring head of the dial indicator is at the position of 10mm elongation and acts on the action surface of the raised block.

[0039] When the end face action end is in the theoretical position, pull out the long positioning pin, rotate the handle nut to drive the slotted screw to move laterally, and then drive the end face action end to move toward the end face axis direction of the composite material sleeve beam until the action surface of the end face action end fits with the end face of one side of the composite material sleeve beam. At this time, the rotation scale value a of the dial indicator acting on the action surface of the raised block should be recorded. The actual axial size deviation of the composite material sleeve beam is Δ=5-a. If Δ>0, the actual axial size of the composite material sleeve beam is larger than the theoretical size; if Δ<0, the axial size of the composite material sleeve beam is smaller than the theoretical size.

[0040] The structural diagram of the fixed end of the beam end face is shown in Figure 8. The fixed end of the beam end face adopts a structural form, positioning and movement method similar to the adjustable end of the beam end face. The fixed end of the beam end face is mainly composed of the end face action end, the slotted screw rod, the handle nut, the T-key, the sleeve, the positioning long pin and other components.

[0041] The action surface of the end face action end is manufactured by extracting the outer shape of the end face of the other side of the composite material sleeve beam. The end face action end is designed with a slotted position at the position of the edge strips on both sides of the composite material sleeve beam. A placeholder is placed at the slotted position. The placeholder is extracted and manufactured according to the outer shape of the edge strips on both sides of the composite material sleeve beam. The purpose of the placeholder is to ensure that the composite material sleeve beam is in the center position of the end face action end. The end face action end is fixed to the slotted screw by connecting it with a metal locating pin.

[0042] The rotation of the handle nut drives the slotted screw to move horizontally, and then drives the end face action end to move horizontally. A through hole is designed at the connection between the sleeve and the slotted screw, and the diameter of the positioning long pin is consistent with the diameter of the through hole. When the positioning long pin is inserted into the through hole of the sleeve and the slotted screw, the theoretical spacing in the axial direction between the action surface of the end face action end and the end face of the other side of the composite material sleeve beam is 0mm, that is, the theoretical position of the end face of the other side of the composite material sleeve beam.

[0043] The structural schematic diagram of the edge strip profile plate is shown in Figure 9. The edge strip profile plate action surface is manufactured by extracting the edge strip profile of the composite material sleeve beam and offsetting it outward by 2mm as a reference. The edge strip profile plate is connected to the support plate through screws and positioning pins. The support plate is positioned and connected to the L-shaped support through screws and positioning pins, and the L-shaped support is fixed to the platform by a mechanical connection method of screws and positioning pins.

[0044] When measuring the flange profile of a composite material sleeve beam, use a feeler gauge to measure the gap between the flange profile clamp and the flange profile of the composite material sleeve beam. The theoretical gap value is 2mm. The actual deviation of the flange profile of the composite material sleeve beam is calculated based on the gap value measured by the feeler gauge.

[0045] If the actual gap value measured by the feeler gauge is 3mm, the actual deviation of the outer surface of the composite material sleeve beam flange is -1mm.

[0046] If the actual gap value measured by the feeler gauge is 1mm, the actual deviation of the outer surface of the composite material sleeve beam flange is 1mm.

[0047] The structural diagram of the sleeve assembly part is shown in Fig.10 The sleeve assembly part is a connecting component, which is mainly composed of a column, a tensioner support, a tensioner, a lateral tensioner, a support, a handle nut, a drill jig, a connecting piece, a drill jig back plate, a tensioner sleeve and other components.

[0048] The connection component can realize functions such as supporting the composite material sleeve beam, positioning the composite material sleeve beam, and realizing the drilling and connection of the composite material sleeve beam.

[0049] Among them, the structural form, connection form and function of the column, tensioner support, tensioner, lateral tensioner, support, handle nut and tensioner sleeve are as described above.

[0050] The drilling jig is designed with an action table, which is flush with the end face of the connecting piece. The drilling jig is positioned on the connecting piece through the action table and metal positioning pins are inserted into the pin holes of the connecting piece.

[0051] The drilling jig has a through hole design, the support has a through hole design, and the outer diameter of the lateral tightener is accommodated within the through hole size, so that the lateral tightener passes through the support and the drilling jig and acts on the edge strip surface of the composite material sleeve beam to ensure that the edge strip surface of the composite material sleeve beam is fixed.

[0052] The connector is fixed on the support by a positioning pin, and a pin hole is designed on the connector. The connector can be connected and fixed to the drill template by a metal positioning pin through the pin hole. The connector is designed with a drill template back plate, which acts on the edge strip surface side of the composite sleeve beam. The drill template back plate is manufactured by extracting the edge strip profile surface of the composite sleeve beam and offsetting it outward by 2mm. The drill template back plate is designed with a through hole at the bushing hole position of the drill template. The purpose is to ensure that when the drill template passes through the drill bit and drills the sleeve assembly part of the composite sleeve beam, the drill hole lead-out end has a support to prevent fiber splitting during the drilling process of the composite sleeve beam.

[0053] Beneficial effects of the present invention:

[0055] (2) The present invention innovatively proposes a metal joint structure to replace the commonly used metal hinge arm, and simplifies the metal hinge arm into a metal joint with drilling, connection, and shape compensation. The metal joint is equipped with high-precision bolts and matching nuts to realize the connection function of the metal joint after drilling, ensuring the precise connection between the metal joint and the composite material sleeve beam. A gap gasket can be added between the metal joint and the composite material sleeve beam to achieve process requirements such as thermal calibration.

DETAILED DESCRIPTION

[0077] The method for using the assembly tool of the composite material sleeve beam comprises the following steps:

[0078] 1. Prepare multiple secondary parts - composite beams.

[0079] 2. Remove the metal joint part 3 from the assembly tool, remove the side where the connector 16 and the connector 36 are connected to the support 17 respectively, and keep the connector 16 and the connector 36 in the open state.

[0080] 3. The tensioner 14 is rotated to a low position, not higher than the action surface of the support plate 40, to ensure that when placing the secondary component-composite beam, the tensioner 14 does not interfere with the web surface of the secondary component-composite beam.

[0081] 4. At the adjustable end part, i.e., the adjustable end 22 of the beam end face, the handle nut 26 rotates to drive the slotted screw 25 to move horizontally, and then drives the end face action end 23 to move horizontally. A through hole is designed at the connection between the sleeve 28 and the slotted screw 25, and the diameter of the positioning long pin 30 is consistent with the diameter of the through hole. When the positioning long pin 30 is inserted into the through hole, the initial spacing between the action surface of the end face action end 23 and the end face of one side of the composite material sleeve beam in the axial direction is 5mm, and the measuring head of the dial indicator 24 is at the position of 10mm elongation and acts on the action surface of the protruding block 29.

[0082] 5. At the fixed end part, i.e., the fixed end 32 of the beam end face, the handle nut 26 rotates to drive the slotted screw 25 to move horizontally, and then drives the end face action end 23 to move horizontally. A through hole is designed at the connection between the sleeve 28 and the slotted screw 25. The diameter of the positioning long pin 30 is consistent with the diameter of the through hole. When the positioning long pin 30 is inserted into the through hole, the action surface of the end face action end 33 is located at the theoretical zero point position of the end face of one side of the composite material sleeve beam. A placeholder 39 is placed in the slot of the end face action end 33.

[0083] 6. Place the secondary parts-composite material beams in sequence on the assembly tooling according to the fitting structure of the composite material fitting beams, so as to facilitate the subsequent positioning and fixing of the secondary parts-composite material beams.

[0084] 7. The metal joint part 3 is connected to the connecting piece 16 and the connecting piece 36 through the positioning pin.

[0085] 8. Connect the connecting pieces 16 and 36 in the open state to the support 17 through the positioning pins, and keep the connecting pieces 16 and 36 in the closed working state.

[0086] 9. In the secondary component - the composite beam component near the fixed end 32 of the beam end face, process compensation gaskets are inserted into the gaps between the working surface 5 on the edge surface side of the metal joint part 3 and the working surface 6 on the web surface side and the edge surface and web surface of the composite sleeve beam respectively. The process compensation gasket is determined according to the process requirements.

[0087] 10. Tighten the tensioner 14 outside the web surface of the secondary component-composite beam near the fixed end 32 of the beam end face so that the web surface of the secondary component-composite beam and the metal joint part 3, the process compensation gasket, etc. are closely matched. Because the action surface of the support plate 40 is 3 mm lower than the theoretical web outer shape surface of the composite sleeve beam, that is, the secondary component-composite beam near the fixed end 32 of the beam end face is placed at a position 3 mm lower than the theoretical position, tightening the tensioner 14 will drive the end surface of the secondary component-composite beam near the fixed end 32 of the beam end face to rise continuously, and the end surface of the secondary component-composite beam near the fixed end 32 of the beam end face may not fit partially with the end surface action end 33. It is necessary to use a non-metallic tool such as a rubber hammer to act on the end surface of the secondary component-composite beam to ensure that the end surface of the secondary component-composite beam fits the end surface action end 33 completely, and finally reach a state where the tensioner 14 cannot be tightened.

[0088] 11. Use the lateral tightener 15 to act on the edge strip surface of the secondary component-composite beam near the fixed end 32 of the beam end surface, thereby completing the positioning and fixing of the secondary component-composite beam near the fixed end 32 of the beam end surface.

[0089] 12. According to the process requirements, the axial dimension deviation L of the composite sleeve beam is given, that is, the deviation between the axial dimension of the composite sleeve beam required by the actual assembly and the theoretical dimension, -5mm≤L≤5mm. At the adjustable end part, that is, the adjustable end 22 of the beam end face, when positioned by the positioning long pin 30, the initial spacing in the axial direction between the action surface of the end face action end 23 and the end face of one side of the composite sleeve beam is 5mm.

[0090] According to the comparison between the axial dimension deviation L of the composite sleeve beam and the initial spacing of 5mm, the rotation scale value a of the dial indicator 24 acting on the action surface of the protruding block 29 is given, a=5-L. The slotted screw 25 is driven to move horizontally by the rotation of the handle nut 26, and the handle nut 26 rotates in a unidirectional movement direction, that is, the unidirectional movement drives the end surface action end 23 to move toward the end surface axis direction of the composite sleeve beam, and at the same time, the dial indicator 24 acting on the action surface of the protruding block 29 rotates, and the rotation scale value a, the action surface of the end surface action end 23 reaches the set position required by the process.

[0091] If the axial dimension deviation L of the composite sleeve beam is 2 mm, the rotation scale value a is 3 mm.

Because the effective surface of the support plate 40 is 3 mm lower than the theoretical web outer surface of the composite material sleeve beam, that is, the secondary component-composite material beam with the adjustable end 22 near the end face of the beam is placed at a position 3 mm lower than the theoretical position, tightening the tightening device 14 will drive the end face of the secondary component-composite material beam near the adjustable end 22 of the end face of the beam to continuously rise, and there may be a partial mismatch between the end face of the secondary component-composite material beam near the adjustable end 22 of the end face of the beam and the effective end 23 of the end face.

The preferred rivet specification is HB6306-2.5xL.

Use the drilling tool: a 90° angular air drill to drill the bushing 4 along the metal joint to complete the drilling of the composite material sleeve beam edge strip. After the drilling is completed, use high-precision bolts 8 and nuts 9 to connect the metal joint bushing hole 4 and the composite material sleeve beam edge strip, with the bolt head located within the inner surface of the composite material sleeve beam edge strip and the nut located on the outer surface of the composite material sleeve beam edge strip.

[0098] 17. Use a feeler gauge to measure the gap between the edge strip surface clamping plate 20 and the composite material sleeve beam edge strip surface, and reserve a gap value of 2mm. Convert the actual composite material sleeve beam edge strip surface deviation based on the gap value measured by the feeler gauge.

[0099] If the actual gap value measured by the feeler gauge is 3mm, the actual surface deviation of the composite material sleeve beam flange is -1mm.

[0100] If the actual gap value measured by the feeler gauge is 1mm, the actual surface deviation of the composite material sleeve beam flange is 1mm.

The thickness of the process compensation gasket is determined according to the process requirements. Outside the web surface of the secondary component - composite beam near the fixed end of the beam end, a tightening device (14) is tightened to make the inner side of the web surface of the composite sleeve beam, the metal joint part (3) and the process compensation gasket fit tightly. Step 14: Use a lateral tightener (15) to act on the edge strip surface of the secondary component-composite beam near the fixed end of the beam end surface, thereby completing the positioning and fixing of the secondary component-composite beam near the fixed end of the beam end surface; Step 15: Install the drilling jig (35), and use the lateral tightener (15) to act on the edge strip surface of the composite material sleeve beam to ensure that the sleeve of the composite material sleeve beam is tightly fitted; Step 16: The drilling template back plate (18) is connected and fixed by the connecting piece (16) and the connecting piece (36); a drilling tool is used: a 90° angular air drill is used to drill a hole in the bushing (4) along the metal joint to complete the drilling of the composite material sleeve beam edge strip; after the drilling is completed, a high-precision bolt (8) and a nut (9) are used to connect the metal joint bushing hole 4 and the composite material sleeve beam edge strip, with the bolt head located within the inner surface of the composite material sleeve beam edge strip and the nut located on the outer surface of the composite material sleeve beam edge strip; Step 17: Use a feeler gauge to measure the gap between the edge strip outer surface clamping plate (20) and the composite material sleeve beam edge strip outer surface, and reserve a gap value of 2 mm. According to the gap value measured by the feeler gauge, the actual composite material sleeve beam edge strip outer surface deviation is converted; Step 18: Remove the positioning pin on the metal joint part (3), withdraw the lateral tensioner (15), withdraw the tensioner (14), remove the connecting piece (16), and the side of the connecting piece (36) connected to the support (17), respectively, and keep the connecting piece (16) and the connecting piece (36) in an open state; pull out the positioning long pin (30) of the beam end fixed end (32), rotate the handle nut (26) to make the end surface action end (23), and the end surface action end (33) move laterally away from the composite material sleeve beam, remove the composite material sleeve beam from the assembly tool and transfer it to the downstream assembly, such as the composite material rudder box section assembly.
