[0016] Example 1 like Figure 1-4 The chassis suspension quick-change common fixture shown includes: a base frame 1, a rotating disk 2, a suspension tray 3, a first positioning and limiting part 4, and a second positioning and limiting part 5; the interior of the base frame 1 adopts a grid-shaped structure, and its top surface is provided with several crisscrossing grooves 11, providing a flexible base for the installation and adjustment of other components; The rotating disk 2 is installed at the center position below the base frame 1 to realize the rotation function of the entire fixture, which facilitates assembly operations from different angles; The suspension tray 3 is positioned above the base frame 1. Its core is constructed from multiple modularly spliced ​​slats 31, which are raised by pads 32 to form a support platform that can adapt to different chassis suspension models. Specifically, the bottom slats 31 of the suspension tray 3 are arranged in an alternating pattern with the crossbars of the base frame 1. Above these bottom slats 31, pads 32 are installed at the middle and both ends. Slats 31 are then built on the pads 32 to form a stable top plate frame. Finally, according to the actual support requirements, several slats 31 are evenly laid on the top plate frame to complete the construction of the entire tray. The first positioning and limiting part 4 is provided in multiple parts, which are used to limit and fix the suspension tray 3 from the outside. The part includes a first fixing plate 41, a first limiting plate 42, and a lateral limiting plate 43. The first fixing plate 41 is L-shaped and is slidably fixed in the slide groove 11 on the periphery of the base frame 1 by bolts. The first limiting plate 42 is connected to the first fixing plate 41 by bolts. Its end is cut and punched and bent to form a unique baffle 421 structure with one half vertically upward and the other half vertically downward. The baffle 421 is used to tightly abut the corresponding edge of the suspension tray 3. An extension connector 422 is also provided below the end of the first limiting plate 42. The lateral limiting plate 43 is located outside the downwardly bent baffle 421 and is connected to the extension connector 422 by fasteners to provide additional lateral restraint. The second positioning limiting part 5 is also provided in multiples. It is installed on the sliding groove 11 of the grid structure inside the base frame 1. It is mainly used for internal limiting from the gap between the top strips 31 of the suspension tray 3. The second positioning limiting part 5 is symmetrically distributed as a whole. Usually, two are set between two adjacent strips 31 to provide balanced clamping force.

[0017] In this embodiment, the first limiting plate 42 is an L-shaped structure with a reinforcing rib 423 in the middle to enhance structural rigidity, and the part connected to the baffle 421 is designed as an isosceles trapezoid to facilitate installation and force transmission; the first fixing plate 41 can be moved to the optimal position in the slide groove 11 according to the final stacking structure of the suspension tray 3 and then locked by bolts; in addition, the number of first positioning limiting parts 4 arranged on each side of the base frame 1 corresponds to the number of the short sides of the strips 31 on the suspension tray 3 facing outward, ensuring that there are no dead angles in the limiting.

[0018] Example 2 Based on Example 1, in this example, as... Figure 4 The chassis suspension quick-change common fixture shown includes a second positioning and limiting part 5, which includes a second fixing plate 51 and a second limiting plate 52. The second fixing plate 51 is fixed to the slide groove 11 of the base frame 1 by bolts, and the second limiting plate 52 is fixed to the second fixing plate 51 by bolts.

[0019] In this embodiment, the second fixing plate 51 has upwardly bent edges on both sides, thereby forming a space for the second limiting plate 52 to slide; the upper part of the second fixing plate 51 has bolt holes; the lower middle part of the second limiting plate 52 is provided with an elongated adjustment groove 521. When the height needs to be adjusted, the second limiting plate 52 can move up and down in the sliding space. After the position is determined, a bolt is passed through the adjustment groove 521 and screwed into the bolt hole on the upper part of the second fixing plate 51 to tighten it.

[0020] In this embodiment, the upper end of the second limiting plate 52 serves as the limiting end, and its designed width is exactly equal to the interval between the adjacent top strips 31, allowing it to be precisely inserted into the gap. The installation height of the second limiting plate 52 is adjusted to be flush with the upper surface of the top strip 31, thereby effectively limiting the displacement of the strip 31 without interfering with the placement of the workpiece.

[0021] In this embodiment, a third positioning and limiting part is also added to the base frame 1. This third positioning and limiting part is mainly used to assist in positioning and fixing the pad block 32 used to elevate the suspension tray 3 inside the grid-shaped structure of the base frame 1, preventing it from moving during operation and enhancing the stability of the entire support structure.

[0022] It should be noted that the above description is merely a technical solution of the utility model and not a limitation. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the utility model without departing from the scope of the present utility model, and all such modifications and substitutions should be covered within the scope of the claims of the present utility model.
