Description

Technical Field

[0001] The present invention relates to the technical field of flipping and clamping tooling, and particularly to a flipping fixture for automobile panel processing. Background Art

[0002] Automobile panel processing is a key link in automobile manufacturing and maintenance, involving cutting, forming, welding, and surface treatment of various materials (such as steel plates, aluminum alloys, composite materials, etc.).

[0003] In automobile panel processing, flipping fixtures are mainly used in processes that require multi-angle operation or double-sided processing to improve efficiency, ensure accuracy, or reduce repeated clamping. Typical application scenarios include welding assemblies, stamping, machining, quality inspection, painting, and sheet metal shaping.

[0004] However, due to design defects, the existing flipping fixtures generally have the following problems when used for clamping and flipping automobile panels: 1. The feeding and flipping efficiency of automobile panels is low, and the degree of automation is insufficient. Specifically, the traditional conveying system can only complete one-way conveying, and the flipping of the panel depends on manual labor or additional equipment, resulting in process interruption and low efficiency; when the panel size changes, the clamping mechanism needs to be adjusted manually, and it is difficult to quickly adapt to different specifications.

[0005] 2. The flexibility of panel attitude adjustment is poor, and there are machining blind spots. Specifically, the traditional clamping mechanism has limited degrees of freedom (such as only being able to rotate around a single axis), and it is difficult to achieve complex angle adjustments (such as side flipping, tilting, etc.), resulting in welding / spraying blind spots; the flipping and clamping parts are fixed, and it is easy to interfere with the processing tools.

[0006] 3. The docking or lapping accuracy of multiple panels is low, and the welding / assembly adaptability is poor. Specifically, when multiple panels are docked, the position needs to be adjusted repeatedly, relying on manual positioning, with low efficiency and easy errors; the traditional fixture cannot dynamically adapt to different welding angles (such as inclined plane and curved surface welding).

[0007] 4. The clamping stability is insufficient, affecting the processing quality. Specifically, the panel is prone to offset and vibration during conveying or flipping, resulting in processing errors (such as welding misalignment, uneven spraying); the traditional clamping mechanism (such as single-point clamping) has uneven stress and may damage the surface of the panel.

[0008] 5. The process connection is not coherent, and the production cycle is long. Specifically, each link (conveying, flipping, processing, output) needs to be operated independently, the process is fragmented, and the production cycle is extended; the traditional equipment cannot dynamically switch the clamping mode according to the processing requirements.

[0009] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve. Summary of the Invention
