Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to a support structure that avoids interference and has an automatic flipping mechanism. Background Technology
[0002] When a company is developing a new vehicle model, a new chassis may emerge. If the company's existing chassis production line is incompatible with the new chassis, and the new chassis utilizes previous models, interference between the chassis and the sub-assembly / assembly platforms may prevent sub-assembly and assembly. For example, interference between the engine support of the sub-chassis being switched and the final assembly / assembly pallet prevents the engine and front suspension assembly from being sub-assembled, and also prevents assembly with the body. Given that existing support structures are all rigid, even after avoiding interference points, removal after assembly is difficult. The current removal process requires manual control of a lifting platform, lowering the support, and then manually removing it, which is inefficient and does not meet production cycle requirements. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a structural design that avoids the need for separate assembly and reassembly. The supporting structure incorporates a rotating pin and a flip-up plate to meet these requirements, and it also allows for automatic and rapid retraction. After reassembly, the employee simply presses the retraction and descent button on the reassembly platform, causing the platform and support assembly to automatically descend without further manual intervention. This eliminates the risk of damage to the support and workpieces and improves production efficiency. The specific technical solution is as follows:
[0004] A support structure with an automatic flipping mechanism that avoids interference includes a positioning pin, a positioning pin mounting column, a flipping plate, a fixed guide block, a rotating shaft pin, a rotating shaft pin mounting bracket, a support mounting beam, a column support, and a support base support. The support base support matches the mounting holes on the assembly platform. A support mounting beam is provided on the upper part of the support base support. A column support is installed on one side of the support mounting beam, and a rotating shaft pin mounting bracket is installed on the other side of the support mounting beam. A flipping plate is mounted on the rotating shaft pin mounting bracket via a rotating shaft pin. A positioning pin mounting column is provided on the upper part of the flipping plate, and a positioning pin is provided on the upper part of the positioning pin mounting column. A fixed guide block is provided on the outer inclined surface of the flipping plate.
[0005] Furthermore, the inclined surface of the fixed guide block is set as a smooth surface.
[0006] Furthermore, the support column is mounted on the support mounting beam via a support column mounting plate, and the support column mounting plate is horizontally or vertically arranged with the support mounting beam.
[0007] Furthermore, the height of the positioning pin, positioning pin mounting column, and flip plate after installation is 0.5-0.8 times the width of the supporting mounting beam.
[0008] Furthermore, the angle of the outer slope of the flip plate ranges from 30 to 75°.
[0009] Normally, the support mechanism is in a vertical position during pre-assembly and assembly. This position avoids interference with the workpiece and does not affect the workpiece's disassembly and assembly process. After assembly, the support descends vertically along with the assembly table. During this process, the guide block of the support mechanism contacts the workpiece and automatically rotates and flips to a horizontal position around the rotating shaft pin during descent. This process does not require manual intervention and can quickly detach the assembly pallet and related bracket structures from the vehicle, ensuring efficient assembly and production.
[0010] This invention features a rotating shaft pin installed between a tilting plate and a mounting bracket. A fixed guide block with an extremely low coefficient of friction is mounted on the tilting plate. The contact surface between this guide block and the workpiece is extremely smooth and will not scratch the workpiece during contact. This allows the support structure to descend smoothly with the assembly pallet. Upon contact with the workpiece, the smooth inclined surface of the guide block automatically rotates around the rotating shaft pin, knocking the workpiece aside and allowing the assembly platform and support assembly to descend smoothly together, eliminating a series of problems associated with the original support structure. This ingenious design avoids interference while automatically tilting; the automatic tilting of the platform and support upon contact with the workpiece during descent effectively improves production efficiency.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] A support structure with an automatic flipping mechanism that avoids interference includes a positioning pin 1, a positioning pin mounting column 2, a flipping plate 3, a fixed guide block 4, a rotating shaft pin 5, a rotating shaft pin mounting bracket 6, a support mounting beam 7, a column support 9, and a support base support 10. The support base support 10 matches the mounting holes on the assembly platform. The support mounting beam 7 is provided on the upper part of the support base support 10. The column support 9 is installed on one side of the support mounting beam 7, and the rotating shaft pin mounting bracket 6 is installed on the other side of the support mounting beam 7. The flipping plate 3 is mounted on the rotating shaft pin mounting bracket 6 via the rotating shaft pin 5. The positioning pin mounting column 2 is provided on the upper part of the flipping plate, and the positioning pin mounting column 2 is provided on the upper part of the positioning pin 1. The fixed guide block 4 is provided on the outer inclined surface of the flipping plate 3.
[0017] The inclined surface of the fixed guide block is set as a smooth surface. The angle of the inclined surface ranges from 30-75°. The column support 9 is installed on the support mounting beam 7 through the column support mounting plate 8, and the column support mounting plate 8 is set horizontally or vertically to the support mounting beam 7. After installation, the positioning pin 1, the positioning pin mounting column 2, and the flip plate 3 are 0.5-0.8 times the width of the support mounting beam 7.
[0018] Normally, the support mechanism is in a vertical position during pre-assembly and assembly. This position avoids interference with the workpiece and does not affect the workpiece's disassembly and assembly process. After assembly, the support descends vertically along with the assembly table. During this process, the guide block of the support mechanism contacts the workpiece and automatically rotates and flips to a horizontal position around the rotating shaft pin during descent. This process does not require manual intervention and can quickly detach the assembly pallet and related bracket structures from the vehicle, ensuring efficient assembly and production.
[0019] This invention features a rotating shaft pin installed between the flip plate and the rotating shaft pin mounting bracket. A fixed guide block with an extremely low coefficient of friction is mounted on the flip plate. The contact surface between the fixed guide block and the workpiece is extremely smooth and will not scratch the workpiece during contact. This allows the support structure to descend smoothly along with the assembly pallet. After the smooth inclined surface contacts the workpiece, the flip plate and the fixed guide block assembly automatically rotate around the rotating shaft pin and knock it down, thus avoiding the workpiece. The assembly platform and support assembly descend smoothly together, eliminating a series of problems associated with the original support structure.
