The lifting lugs 71 are located at the upper end of the fixture frame 1 and are used for lifting and transporting the assembly fixture. The auxiliary support devices include an upper support unit 72 and a lower support unit 73, which are used to support the frame assembly to be assembled. In some embodiments, the upper support unit 72 is located between the upper half-frame locator 41 and the baffle joint locator 3, and the lower support unit 73 is located between the lower half-frame locator 42 and the baffle joint locator 3.

[0037] Specifically, both the upper support unit 72 and the lower support unit 73 of the auxiliary support device include an adjustment component. This adjustment component is used to adjust the position of the upper support unit 72 and the lower support unit 73 to adapt to the shape of the component mounted on the assembly fixture, thereby supporting the parts of the frame assembly to be assembled and preventing deformation of the frame assembly due to gravity. This achieves shape preservation of the component mounted on the assembly fixture.

[0040] Example 2

[0041] See Figure 1 and Figure 2 This embodiment provides a tooling assembly system, including the assembly tooling and docking frame assembly as described in Embodiment 1. The assembly tooling is used to assemble a docking frame assembly including an upper frame 91, a lower frame 92, a tie rod 93, a baffle 94, and a joint assembly. The joint assembly includes a docking joint 95 and a baffle joint 96.

[0042] The positioning part of the assembly fixture is used to position the docking frame assembly. Specifically, the upper half frame positioner 41 is used to position the upper half frame 91, the lower half frame positioner 42 is used to position the lower half frame 92, the upper docking joint positioner 51 and the lower docking joint positioner 52 are used to position the docking joint 95, and the baffle joint positioner 3 is used to position the baffle joint 96.

[0043] Specifically, the upper frame locator 41 includes a first positioning surface and a detachable first fixing member, and the lower frame locator 42 includes a second positioning surface and a detachable second fixing member. When using the upper frame locator 41, positioning is performed based on the TH hole and web surface of the upper frame 91; when using the lower frame locator 42, positioning is performed based on the TH hole and web surface of the lower frame 92. The mating joint locator includes a third positioning surface and a detachable third fixing member. When using the mating joint locator, positioning is performed based on the intersection hole of the mating joint 95 and the inner stop surface of the fork lug. The baffle joint locator 3 includes a fourth positioning surface and a detachable fourth fixing member. When using the baffle joint locator 3, positioning is performed based on the intersection hole of the baffle joint 96 and the outer fork lug stop surface. In this embodiment, the first fixing member, the second fixing member, the third fixing member, and the fourth fixing member are all positioning pins.

[0044] The tooling assembly system also includes a clamping device, which is used to clamp and fix the parts of the docking frame assembly onto the assembly tooling.

[0045] When tooling assembly system such Figure 2 In the shown configuration, the lifting lug 71 is located at the upper end of the tooling frame 1, facilitating the lifting of the assembly tooling. The upper support unit 72 provides support for the upper half of the frame 91, and the lower support unit 73 provides support for the lower half of the frame 92, thereby preventing deformation of the upper and lower half of the frame 91 and 92 under gravity. This enables the lifting and transportation of the assembly tooling and connecting frame components, as well as the preservation of the shape of the connecting frame components. The tooling interface 8 faces downwards, facilitating assembly with the final assembly station after transportation.

[0046] The tooling assembly system described in this embodiment integrates the assembly, lifting, transportation, shape preservation, and support functions of the docking frame assembly into one unit, reducing tooling and saving costs. Furthermore, only one set of tooling is used throughout the entire assembly process of the docking frame assembly, eliminating the need to transfer tooling, thus shortening the assembly process and improving assembly efficiency. It also prevents deformation of the upper frame 91 and lower frame 92 of the docking frame assembly, improving assembly accuracy and quality.

[0047] This tooling assembly system can first assemble the docking frame components at the sub-assembly station, and then transport the docking frame components and assembly tooling together to the final assembly station. This helps to expand the parallel working surface, reduce the assembly time at the final assembly station, and increase the overall production capacity of the docking frame component assembly line.

[0063] In summary, the assembly fixture of the present invention can be used to assemble complex components with multiple intersection holes, and the movable arrangement of the detachable fastener 6 and the baffle joint locator 3 makes the process passage open and the operation convenient when the assembly fixture is used to assemble the components to be assembled.

[0064] The tooling assembly system equipped with this assembly fixture integrates the assembly, lifting, transportation, conformal shaping, and support functions of the docking frame components into one unit, reducing tooling and saving costs. Furthermore, only one set of tooling is used throughout the entire assembly process of the docking frame components, eliminating the need to transfer tooling, shortening the assembly process, and improving assembly efficiency. It also prevents deformation of the upper half (91) and lower half (92) of the docking frame components, improving assembly accuracy and quality. Moreover, this tooling assembly system can first assemble the docking frame components at the sub-assembly station, and then lift the docking frame components and assembly fixtures together to the final assembly station. This facilitates expanding the parallel working surface, reducing assembly time at the final assembly station, and increasing the overall production line capacity for docking frame component assembly.
