[0011] A floating platform, which is installed on the lifting platform, includes an X-axis adjustment mechanism installed on the upper support, a Y-axis adjustment mechanism installed on the X-axis adjustment mechanism, a horizontal rotation mechanism installed on the Y-axis adjustment mechanism, and a support plate installed on the horizontal rotation mechanism for supporting the suspension assembly. A positioning fixture for the suspension assembly is provided on the support plate.

[0012] The guide limiting mechanism is used to limit the position of the carrier plate when the suspension assembly is transferred from the conveyor line to the carrier plate. It includes a guide wheel limiting member installed on the lower support and arranged vertically, and an insert installed on the carrier plate and arranged facing the guide wheel limiting member.

[0013] In a preferred embodiment of the present invention, the X-axis adjustment mechanism includes a first linear rail arranged laterally along the upper support seat, and a first sliding plate slidably placed on the first linear rail, and the Y-axis adjustment mechanism is installed on the first sliding plate.

[0014] In a preferred embodiment of the present invention, the Y-axis adjustment mechanism includes a second linear rail arranged vertically along the first sliding plate, and a second sliding plate slidably mounted on the second linear rail, wherein the horizontal rotation mechanism is mounted on the second sliding plate.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figure 1-3 As shown, this utility model provides a vehicle body and suspension assembly assembly device, including a body lifting device 1 for transporting the vehicle body, which can drive the vehicle body to move along the moving path of the body lifting device 1.

[0040] The lifting platform 2 is located directly below the vehicle body lifting device 1, and has a lower support seat 21, a scissor mechanism 22 mounted on the lower support seat 21, and an upper support seat 23 mounted on the telescopic end of the scissor mechanism 22.

[0041] The conveyor line is located on the side of the lifting platform 2 away from the vehicle body hanger 1 and is used for the uninterrupted transport of the suspension assembly.

[0042] When the lifting platform 2 is in its low position, it is connected to the conveyor line and is used to place the suspension assembly.

[0043] When the lifting platform is in the high position, it is used to lift the suspension assembly to match the vehicle body and assemble it.

[0044] The floating platform 3, which is installed on the lifting platform 2, includes an X-axis adjustment mechanism 31 installed on the upper support 23, a Y-axis adjustment mechanism 32 installed on the X-axis adjustment mechanism 31, a horizontal rotation mechanism 33 installed on the Y-axis adjustment mechanism 32, and a support plate 34 installed on the horizontal rotation mechanism 33 for supporting the suspension assembly. The support plate 34 is provided with a positioning fixture for the suspension assembly.

[0045] The guide limiting mechanism 4 is used to limit the bearing plate 34 when the suspension assembly is transferred from the conveyor line to the bearing plate 34. It includes a guide wheel limiting member 41 installed on the lower support 21 and arranged vertically, and a fitting member 42 installed on the bearing plate 34 and arranged facing the guide wheel limiting member 41.

[0046] The working principle and beneficial effects of the above embodiments are as follows:

[0047] In the low position state of this utility model: when the lifting platform 2 is in the low position, the scissor mechanism 22 retracts, and the upper support 23 and the floating platform 3 descend to the position where they are connected with the conveyor line. At this time, the suspension assembly can be directly transferred from the conveyor line to the bearing plate 34 of the floating platform 3.

[0048] High position: When it is necessary to assemble the suspension assembly with the vehicle body, the scissor fork mechanism 22 extends, driving the upper support seat 23 and the floating platform 3 to rise to a high position. At this time, the suspension assembly on the floating platform 3 and the vehicle body on the vehicle body hanger 1 are in a suitable assembly position, which facilitates the installation of the suspension assembly.

[0049] After the suspension assembly of this utility model is placed on the support plate 34 of the floating platform 3, the suspension assembly on the support plate 34 can be precisely adjusted and rotated by the X-axis adjustment mechanism 31, the Y-axis adjustment mechanism 32 and the horizontal rotation mechanism 33 to ensure that it is accurately aligned with the installation position of the vehicle body, thereby achieving high-precision assembly.

[0050] When the suspension assembly of this utility model is transferred from the conveyor line to the carrier plate 34, the guide wheel limiting member 41 and the fitting member 42 cooperate with each other to limit the carrier plate 34, ensuring that the suspension assembly can be placed stably and accurately on the carrier plate 34, preventing positional displacement during the transfer process, and improving the subsequent assembly efficiency.

[0051] The multi-directional adjustment function (X-axis, Y-axis and horizontal rotation) of the floating platform 3 of this utility model can precisely adjust the position and angle of the suspension assembly, making its assembly with the car body more accurate, thereby improving the quality and consistency of the car assembly.

[0052] The lifting function of the lifting platform 2 enables automatic material handling and assembly of the suspension assembly, while the guide and limit mechanism 4 ensures the smooth transfer of the suspension assembly, significantly improving the efficiency and quality of automobile assembly.

[0053] In one embodiment,

[0054] like Figure 4-5 As shown, the X-axis adjustment mechanism 31 includes a first linear rail 311 arranged laterally along the upper support 23, and a first sliding plate 312 slidably placed on the first linear rail 311. The Y-axis adjustment mechanism 32 is installed on the first sliding plate 312.

[0055] The first linear guide 311 is arranged laterally along the upper support 23 to provide guidance and support for the first sliding plate 312. The high-precision design of the linear guide ensures the smoothness and accuracy of the sliding process.

[0056] In one embodiment,

[0057] The Y-axis adjustment mechanism 32 includes a second linear rail 321 arranged vertically along the first sliding plate 312, and a second sliding plate 322 slidably mounted on the second linear rail 321. The horizontal rotation mechanism 33 is mounted on the second sliding plate 322.

[0058] The second guide rail 321 is arranged vertically along the first sliding plate 312 to provide guidance and support for the second sliding plate 322. The high-precision design of the guide rail ensures the smoothness and accuracy of the sliding process.

[0059] In one embodiment,

[0060] The aforementioned horizontal rotation mechanism 33 includes a fixed seat 331 located at the center of the second sliding plate 322, a rotating shaft 332 rotatably mounted in the fixed seat 331, and a rotating seat 333 sleeved on the fixed seat 331 and fixedly connected to the rotating shaft 332. The rotating seat 333 is connected to the aforementioned bearing plate 34.

[0061] The aforementioned rotating seat 333 is sleeved on the fixed seat 331 and a rotation gap is left between them, so that the rotating seat 333 can rotate horizontally by an angle φ with the axis of the rotating shaft 332 as the center in the circumferential direction, where φ < 5°.

[0062] Multiple ball bearing seats 334 are evenly distributed on the second sliding plate 322, and the balls on the ball bearing seats 334 are in contact with the bearing plate 34.

[0063] The rotating seat 333 is sleeved on the fixed seat 331 and fixedly connected to the rotating shaft 332. The rotating seat 333 achieves horizontal rotation through the rotating shaft 332, with a rotation angle of φ. The rotating seat 333 is connected to the bearing plate 34 and drives the bearing plate 34 to rotate together.

[0064] The balls on the ball bearing seat 334 reduce friction during rotation, enabling the bearing plate 34 to rotate more smoothly and steadily, further improving assembly accuracy.

[0065] In one embodiment,

[0066] like Figure 7 As shown, a limiting groove for the fitting 42 is provided on the upper support 23, and the limiting groove has a gap with the fitting 42 in both the X and Y directions.

[0067] The limiting groove has a gap with the fitting 42 in both the X and Y directions. This design allows the fitting 42 to move freely within a certain range while limiting its excessive offset, ensuring that the bearing plate 34 remains stable during the adjustment process of X, Y and horizontal rotation.

[0068] In one embodiment,

[0069] For example Figure 6-7 As shown, the guide wheel limiting member 41 includes a guide wheel seat 411 mounted on the lower support seat 21, a U-shaped block 412 mounted on the guide wheel seat 411, and a roller 413 rotatably mounted in the U-shaped block 412. The outer circumferential surface of the roller 413 protrudes from the U-shaped block 412.

[0070] The roller 413 contacts the fitting 42 and serves as a guide and limiter. The design of the roller 413 reduces the friction of the fitting 42 during movement, ensuring that the bearing plate 34 can move smoothly and accurately to the designated position.

[0071] In one embodiment,

[0072] The aforementioned fitting 42 includes an L-shaped guide block 421 mounted on the support plate 34. The L-shaped guide block 421 passes through the aforementioned limiting groove and is vertically connected to an insert 422. The lower end of the insert 422 forms an "eight"-shaped opening, and the width of the "eight"-shaped opening is greater than the aforementioned limiting groove and its corresponding groove width.

[0073] The lower end of the insert 422 forms an "eight"-shaped opening, which allows the insert 42 to achieve precise guiding docking with the guide wheel limiting member 41 at any position in the guide groove.

[0074] In summary:

[0075] This utility model discloses an assembly device for automobile body and suspension assembly. The guide and limiting mechanism enables the bearing plate to accurately align with the suspension assembly, improving the efficiency of subsequent assembly with the body. The floating platform enables precise adjustment of the suspension assembly in multiple directions, effectively improving the quality and consistency of automobile assembly.
