[0002] The composite roof and main air duct are large, molded components, approximately 20 meters in length. They experience significant deformation after demolding. During bonding and assembly, large gaps often form at the joint, resulting in poor adhesion and air leakage. Furthermore, dimensional deviations can affect the installation of interior components, and the positioning of the roof's internal runners can affect the assembly of the handrails. Therefore, it is necessary to design a positioning tool to properly align the main air duct and roof.

[0003] There are some positioning tools in the prior art, such as the roof frame positioning tool, which includes a frame platform and a positioning plate. Multiple positioning cards are set on the longitudinal beam of the frame platform, and a positioning plate is also set on the frame platform, and a positioning assembly is set on the positioning plate. The positioning tool plays a positioning role in the roof welding process, but the positioning references of the multiple positioning structures therein are different, and positioning deviations are prone to occur. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a composite material roof bonding positioning tool and method, which can ensure the consistency of positioning reference and positioning accuracy, and improve the product bonding quality.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: In a first aspect, an embodiment of the present invention provides a composite material roof bonding and positioning tool, comprising: The tooling body is used to support the roof; A plurality of positioning clamps are provided along the length direction of the tooling body, and the positioning clamps are used to vertically compress the main air duct; the positioning clamps are provided with a plurality of positioning notches; The slide groove positioning component cooperates with the positioning notch and the slide groove on the top of the roof to form an interlocking with the positioning card plate.

[0021] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0022] Example 1: This embodiment provides a composite material roof bonding and positioning tool, such as Figure 1 and Figure 2As shown, it includes a tooling body 1, a positioning card plate 5, a slide groove positioning component 6 and a pressurizing component 7. The tooling body 1 is used to support the roof 3, the positioning card plate 5 is used to position the main air duct 2 and the roof 3, the slide groove positioning component 6 simultaneously positions the slide groove 4 and the positioning card plate 5, and the slide groove positioning component 6 and the positioning card plate 5 cooperate to further ensure the positioning accuracy of the main air duct 2 and the roof 3; the pressurizing component 7 is used to ensure the firm fit of the main air duct 2 and the roof 3 during the pressurization process.

[0023] Specifically, the tool body 1 includes a frame 11 and a top plate 12. Figure 7 and Figure 8 As shown, the frame 11 is welded from multiple steel plates distributed horizontally and vertically to form a cross-shaped frame 11 structure, and diagonal braces are added at regular intervals to ensure the rigidity of the frame 11. After welding, the entire structure is polished to make the welds beautiful and smooth, and then anti-corrosion treatment is performed.

[0024] An inward-concave arc structure is formed at the top of the skeleton 11, and a top plate 12 is installed on the top of the skeleton 11. The curvature of the top plate 12 is adapted to the skeleton 11; the contact surface between the skeleton 11 and the top plate 12 is a fitting surface. In this embodiment, the top plate 12 is made of alloy steel plate and is milled as a whole by a machining center to ensure that the curvature meets the requirements.

[0025] like Figure 1 and Figure 2 As shown, multiple positioning plates 5 are arranged along the length of the tooling body 1, each positioned transversely along the top of the tooling body 1. The positioning plates 5 are arranged to cover the length of the main air duct 2. Because the roof 3 is longer than the main air duct 2, positioning plates 5 are also provided on the outside of both ends of the main air duct 2. The positioning plates 5 corresponding to the main air duct 2 are provided with slots that allow the main air duct 2 to pass through and limit its lateral movement. Positioning plates 5 outside the main air duct 2 area do not need to be provided with slots.

[0026] The two ends of the positioning card plate 5 are fixedly connected to the edge of the top plate 12 through the connecting seat 52. In this embodiment, Figure 4 As shown, the connecting seat 52 is an L-shaped angle seat, the bottom surface of the L-shaped angle seat is in contact with the top plate 12, and the side surface is in contact with the positioning card 5. The connection between the positioning card 5, the top plate 12 and the L-shaped angle seat is achieved through a connecting piece, which facilitates the disassembly and assembly of the positioning card 5.

[0027] The roof 3 is arranged on the upper side of the top plate 12 and has a certain curvature. In order to effectively limit the position of the roof 3, as shown in FIG. Figure 3 As shown, the bottom surface of the positioning clamping plate 5 corresponding to the portion of the roof 3 is an arc-shaped segment, having an arc adapted to the top plate 12 and the roof 3 .

[0028] The roof 3 is equipped with several chutes 4. This embodiment utilizes chute positioning members 6 to simultaneously limit the chute 4 and the positioning plate 5, creating a self-locking effect between the positioning plate 5 and the chute 4, ensuring the precise positioning of the main air duct 2 and the roof 3. Therefore, positioning notches 51 are defined at the bottom of the positioning plate 5. Multiple positioning notches 51 are provided along the length of the positioning plate 5, corresponding to the positions of the chute 4. Because the positioning notches 51 engage with the chute positioning members 6, the height of the main air duct 2 after bonding can be controlled by adjusting the positioning plate 5.

[0029] like Figure 5 As shown, multiple chutes 4 located in the same longitudinal column can be simultaneously limited by a chute positioning member 6, and the positioning notches 51 corresponding to several adjacent positioning clips 5 can also be simultaneously limited by a chute positioning member 6. In this embodiment, two adjacent positioning clips 5 correspond to one chute positioning member 6 in the longitudinal direction, and multiple chute positioning members 6 cooperate in the transverse direction. The design of the positioning clips 5 not only takes into account the lateral positioning of the main air duct 2, but also takes into account the limiting of the chute 4, which can improve positioning accuracy and simultaneously ensure the relative position of the roof 3 and the main air duct 2.

[0030] The chute positioning member 6 is a cross-shaped structure, such as Figure 6 As shown, the chute positioning member 6 includes a horizontally arranged limiting portion 61 and a vertically arranged plug-in portion 62. The limiting portion 61 and the plug-in portion 62 are perpendicular to each other to form a cross-shaped structure. The chute positioning member 6 slides longitudinally into the chute 4. The limiting portion 61 contacts the inner wall of the chute 4, the bottom of the plug-in portion 62 contacts the bottom surface of the chute 4, and the top of the plug-in portion 62 plugs into the positioning notch 51. Therefore, the length of the part of the plug-in portion 62 located on the upper side of the limiting portion 61 is greater than the length of the part on the lower side, so as to achieve simultaneous cooperation with the positioning notch 51 and the chute 4. Since the roof 3 has a curvature, the cross-shaped structure located in the chute 4 can limit the radial displacement of the chute 4 relative to the roof 3. At the same time, the plug-in portion 62 can prevent the chute 4 and the positioning clamp 5 from moving in the horizontal direction, that is, horizontal positioning.

[0031] In this embodiment, the chute positioning member 6 is made of stainless steel by machining in a machining center.

[0032] The roof 3 and the main air duct 2 are pressurized by vacuum negative pressure. Due to the deformation problem of large-sized molded parts, the gap between the air duct and the roof 3 will be large. In addition, the high-viscosity epoxy structural adhesive used for bonding the main air duct 2 has a large pressure resistance. If heavy objects are used for pressurization, due to the high viscosity of the adhesive and the large size of the components, there will be local problems of incomplete pressing. This embodiment achieves positioning through the positioning card 5 and the slide positioning component 6. At the same time, a pressurizing component 7 is provided to ensure that the roof 3 and the main air duct 2 are firmly fixed, thereby avoiding the problem of unreliable connection during the pressurization process.

[0033] The pressure components 7 are distributed around the main air duct 2. At both ends of the main air duct 2, multiple longitudinally arranged pressure components 7 are connected to the edge of the top plate 12. At both sides of the main air duct 2, multiple transversely arranged pressure components 7 are connected to the edge of the top plate 12. The pressure components 7 are symmetrically distributed relative to the main air duct 2. Figure 1 and Figure 2 As shown, the pressure member 7 is a door-shaped structure, one end of which presses the edge of the top plate 12, and the other end presses the edge of the main air duct 2, and is fixed by a connecting piece; the door-shaped structure is set to cross the roof 3 to achieve the connection between the main air duct 2 and the tooling body 1.

[0034] In this embodiment, the pressurizing member 7 is made of carbon steel.

[0035] It should be noted that, since positioning clamps 5 are further provided at both ends of the main air duct 2 , the positioning clamps 5 at this position need to be provided with notches to avoid the pressurizing member 7 .

[0036] In this embodiment, a positioning card plate 5, a slide groove positioning component 6 and a pressure component 7 are set on the top surface of the tooling body 1 to ensure the consistency of the positioning reference and the accuracy of positioning; a cross-shaped slide groove positioning component 6 is inserted into the slide groove 4 for radial positioning, and a limit card is used for lateral positioning. The positioning card plate 5 is interlocked with the cross-shaped slide groove positioning component 6 to ensure the relative position of the main air duct 2 and the slide groove 4; combined with the pressure component 7, it can effectively solve the problem of movement of the slide groove 4 when pressure is applied.

[0037] Example 2: This embodiment provides a method for installing a composite material roof bonding and positioning tool, which includes the following steps based on the bonding tool described in Example 1: Step 1: Assemble the tooling body 1.

[0038] A top plate 12 is mounted on the top surface of the welded frame 11 to form the tool body 1 .

[0039] Step 2: Set the roof 3 and main air duct 2 on the tooling body 1.

[0040] Step 3: Insert the chute positioning member 6 into the chute 4 of the roof 3 and install the positioning card 5 so that the positioning notch 51 is plugged into the chute positioning member 6; then connect the pressure member 7 to the main air duct 2 and the tooling body 1.

[0041] Among them, the positioning component and the pressure component 7 are designed with the top surface of the tooling body 1 as the positioning reference, and the demoulding surface of the roof 3 is used as the positioning surface when the tooling body 1 is designed, so that the roof 3 can be completely fitted with the tooling body 1 and the bonding parts can be accurately positioned.

[0042] In this embodiment, the positioning plate 5, through the machined positioning notches 51, ensures multi-level positioning when the main air duct 2 and the chute 4 are bonded together, making the relative positioning more accurate and ensuring that the assembly height of the main air duct 2 meets the requirements. The positioning plate 5 cooperates with the chute positioning member 6 to ensure the relative position of the main air duct 2 and the chute 4, and the pressure member 7 ensures that the pressure is in place.

[0043] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
