Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a positioning and assembly fixture for a gooseneck tailgate hinge. Background Technology

[0002] Currently, some automakers, in order to achieve the assembly and integration of tailgate hinges and control tailgate dimensions, need to manually assemble the tailgate hinges onto the vehicle body, and then adjust the relative position of the tailgate sub-assemblies and hinges through manual intervention or equipment assistance to achieve overall circumferential dimensional matching and control of the tailgate; or they need to use more complex fasteners and product structures to achieve dimensional control; or they need to use complex assembly equipment to complete the separate assembly process of the hinges and tailgate, but at the same time, they still need to make dimensional adjustments to the tailgate at the vehicle body end, making the process quite complicated. In addition, the above are usually the assembly methods for ordinary hinge-type hinges. For gooseneck hinges with longer rotating shaft cantilever arms and larger mounting surface areas, it is even more difficult to achieve a stable mass production assembly process. If traditional assembly and adjustment processes are still used, the production cycle will be slow and the production efficiency will be reduced.

[0003] With the development of the current automotive market, more and more car brands are developing wagon-style station wagon models. Therefore, the application of the gooseneck long cantilever hinge, unique to station wagon models, will become increasingly widespread. Consequently, in the mass production of wagon tailgate assemblies, it is necessary to utilize assembly fixtures that are simple in structure, easy to process, reliable in positioning, and convenient in adjustment to adapt to the assembly and integration of the gooseneck hinge with the tailgate, thereby solving the problems of dimensional adjustment and optimization after assembling the gooseneck hinge on the tailgate.

[0004] CN107263078A discloses a hinge assembly fixture with automatic adjustment function, and CN115366032A discloses a luggage hinge positioning device, a luggage hinge assembly fixture, and a vehicle. The above technical solutions specifically describe the basic structure and sensor-mode assembly and adjustment structure and working logic of ordinary hinge fixtures and linkage-type hinge fixtures. Although they can realize the assembly function of ordinary hinges and linkage-type hinges, they cannot solve or meet the assembly function of special long cantilever gooseneck hinges, and cannot meet the assembly positioning requirements of long cantilever hinges such as gooseneck hinges.

[0005] Therefore, in order to meet the assembly and positioning requirements of long cantilever gooseneck hinges, it is urgent to develop a new type of positioning and assembly tooling. Utility Model Content

The positioning and assembly fixture specifically includes a gooseneck hinge positioning unit 2 for positioning the gooseneck hinges 1 and a tailgate sub-assembly positioning unit 3 for positioning the tailgate sub-assembly.

[0108] Figure 1 The diagram shows the overall assembly fixture for positioning the gooseneck hinge 1. The gooseneck hinge positioning unit 2 and the tailgate sub-assembly positioning unit 3 are two independent modules, used to position the gooseneck hinge 1 and the tailgate sub-assembly respectively. Once each is stably positioned, the next integration and assembly process can proceed. Figure 11.1 and 1.2 are partial views of the gooseneck hinge positioning unit 2 and the tailgate sub-assembly positioning unit 3, respectively. It can be seen that there is no rigid connection structure between the two.

[0109] like Figure 2 As shown, the gooseneck hinge 1 referred to in this embodiment is a special hinge for automobile tailgates. It is shaped like a gooseneck and has the characteristics of a longer rotating shaft cantilever and a larger mounting surface area.

[0110] Figure 3 This diagram illustrates the state of the gooseneck hinge 1 when it is in the released position. As shown, the gooseneck hinge 1 is in the released state on the positioning module. The mechanism mainly consists of a hinge fixture 21, a hinge platform 23, a hinge fixing module 25, a gooseneck fixing module 26, a gooseneck limiting module 28, a gooseneck clamping cylinder (i.e., a gooseneck clamping drive 261), a hinge clamping cylinder (i.e., a hinge clamping drive 251), a slide drive cylinder (i.e., a slide drive 223), a guide rail 222, and a slide base plate 221. The hinge clamping cylinder and the gooseneck clamping cylinder respectively drive the hinge clamping block 253 and the gooseneck clamping block 263 to rotate, thus achieving the clamping and fixing function of the gooseneck hinge 1. The slide drive cylinder mainly drives the hinge platform 23 to move forward and backward, so as to realize the gooseneck hinge positioning unit 2 to move forward and backward along the guide rail 222, so as to complete the contact and engagement between the gooseneck hinge 1 and the tailgate sub-assembly.

[0111] Figure 4 This diagram illustrates the state of the gooseneck hinge 1 during positioning and clamping. As shown in the diagram, the gooseneck hinge 1 is clamped on the hinge positioning platform 24. The hinge clamping block 253 and the gooseneck clamping block 263 are respectively clamped under the drive of the hinge clamping cylinder and the gooseneck clamping cylinder, i.e., in the working state. At this time, the gooseneck hinge 1 can be securely fixed in place.

[0112] Figure 5-6 These are schematic diagrams showing the gooseneck hinge fixture with and without the gooseneck hinge 1. When the gooseneck hinge 1 is positioned on the hinge positioning table 24, the hinge portion 11 of the gooseneck hinge 1 is in close contact with the platform surface of the hinge positioning table 24.

[0113] Figure 7 This is an enlarged view of the gooseneck hinge module. The diagram details the structure and location of the gooseneck hinge 1, each clamping block, and each adjusting shim 4. During the dimensional adjustment phase, the shims 4 can be used to make targeted adjustments and optimizations to the above components based on the actual dimensions, achieving the desired dimensional optimization.

[0114] Figure 8This is an anatomical diagram of the hinge fixing module 25. The diagram shows the main structure of the hinge fixing module 25 and the flexible adjustment method of the height of the hinge Z-direction clamping block 2531 and the hinge X-direction clamping block 2532 through the shims 4.

[0115] Figure 9-11 This is a schematic diagram of the hinge positioning platform 24 and the gooseneck limiting module 28. The main structure of the hinge positioning platform 24 and the gooseneck limiting module 28 can be seen in detail in the figure. Many components can be independently adjusted through independent shims 4.

[0116] Figure 12-17 This is a schematic diagram of each positioning module in the tailgate sub-assembly positioning unit 3. By adjusting the corresponding shims 4, the positioning adjustment of the tailgate sub-assembly in the X, Y, and Z directions can be achieved.

[0117] The assembly method of the positioning assembly fixture in this embodiment is as follows:

[0118] (1) The operator places the gooseneck hinge 1 onto the hinge positioning table 24 of the gooseneck hinge positioning unit 2. After ensuring the part is in place, the operator presses the start button. The hinge clamping cylinder drives the flip clamping connecting arm 252 and the hinge clamping block 253 to flip, thereby clamping the hinge part 11 of the gooseneck hinge 1. Then, the gooseneck clamping cylinder drives the gooseneck clamping connecting arm 262 to flip, thereby clamping the gooseneck clamping block 263 onto the neck 12 of the gooseneck hinge 1. After completing the above actions, the gooseneck hinge 1 is securely fixed.

[0119] (2) After the gooseneck hinge 1 is securely positioned, the operator places the tailgate sub-assembly onto the tailgate sub-assembly positioning unit 3, ensuring that the tailgate sub-assembly is fully fitted with the first X-direction positioning block 321, the second X-direction positioning block 322, the X-direction auxiliary positioning block 323, the Y-direction positioning module 33, and the Z-direction positioning module 34. The tailgate sub-assembly is then clamped by the clamping cylinder, at which point the tailgate sub-assembly is securely fixed.

[0120] (3) After the gooseneck hinge 1 and the tailgate assembly are securely fixed, the operator starts the button and the slide table drive cylinder drives the hinge table frame 23 to move forward and backward along the guide rail 222, thereby completing the contact and fit between the gooseneck hinge 1 and the tailgate assembly.

[0121] (4) After the gooseneck hinge 1 contacts the tailgate sub-assembly, the hinge is manually tightened to the tailgate sub-assembly using a bolt gun, completing the hinge assembly. Finally, the operator removes the assembled tailgate, and the hinge fixture returns to its initial position, thus continuing the production cycle.

[0122] This embodiment of the gooseneck tailgate hinge positioning and assembly fixture is mainly used for the integration of gooseneck tailgate hinges and tailgate sub-assemblies in wagons and SUVs. It enables precise and stable installation of the gooseneck hinge on the tailgate sub-assembly and accurately controls the dimensions of the tailgate assembly. By using this fixture, the goals of dimensional control, dimensional adjustment, and dimensional optimization after assembling the gooseneck hinge can be efficiently achieved, effectively solving the assembly problems of unpositionable and slow-adjustable gooseneck hinges. Using this hinge fixture on the tailgate assembly line not only fulfills the basic function of assembling gooseneck hinges but also enables rapid adjustment of the relative position of the tailgate sub-assembly and the gooseneck hinge, improving the efficiency of tailgate assembly dimensional optimization, providing a convenient method for dimensional correction, thereby reducing production waiting time and assembly rework.
