[0011] This invention utilizes a rotating hexagonal prism-shaped first tightening adjustment end to drive a limiting pin to rise and fall within the limiting support column via a threaded mechanism. This allows for the adaptation of flanges of varying thicknesses, ensuring the workpiece's bottom surface is stably supported and securely clamped. Each clamping device, via a threaded adjustment rod, pushes a pressing and fixing end to move radially. Combined with the sliding positioning of a sliding limit frame on the limiting support base, this achieves the clamping of the outer edges of flanges of different diameters. The limiting pin is inserted into the center hole of the flange to prevent radial displacement. The pressing and fixing ends of multiple clamping devices simultaneously lock the outer wall of the flange, evenly distributing stress. The first tightening adjustment end and the limiting pin form a support platform, preventing workpiece sinking or tilting due to processing vibrations, eliminating displacement and shaking during processing, and ensuring the accuracy of drilling, milling, and other machining operations. An electric rotating base drives the entire mounting plate and the clamped flange to rotate, allowing for multi-angle machining without disassembling the workpiece, improving processing efficiency, and avoiding repeated clamping errors. Both the first and second tightening adjustment ends employ hexagonal prism structures, making them compatible with standard wrenches and easy to operate.

[0002] An automotive flange is a disc-shaped metal part with mounting holes around its perimeter, primarily used to connect and secure automotive components. It plays a crucial role in automobiles, tightly connecting the wheels to the axle via bolts to ensure the stability of the wheel-axle connection during driving. It transmits braking force from the tires to the axle, influencing the suspension system's movement and directly impacting vehicle stability and handling. The manufacturing process of automotive flanges involves reference machining, rough machining, and precision machining. However, the manufacturing process often fails to achieve precise locking and positioning of flanges of different sizes and thicknesses, leading to processing difficulties and potential displacement and wobbling. This hinders accurate drilling and other fine-tuning of the flange's outer end face. Therefore, a device is needed to address these issues. Utility Model Content

This allows for the adaptation of flanges of varying thicknesses, ensuring the workpiece's bottom surface is stably supported and securely clamped. Each clamping device, via a threaded adjustment rod, pushes a pressing and fixing end to move radially. Combined with the sliding positioning of a sliding limit frame on the limiting support base, this achieves the clamping of the outer edges of flanges of different diameters. The limiting pin is inserted into the center hole of the flange to prevent radial displacement. The pressing and fixing ends of multiple clamping devices simultaneously lock the outer wall of the flange, evenly distributing stress. The first tightening adjustment end and the limiting pin form a support platform, preventing workpiece sinking or tilting due to processing vibrations, eliminating displacement and shaking during processing, and ensuring the accuracy of drilling, milling, and other machining operations. An electric rotating base drives the entire mounting plate and the clamped flange to rotate, allowing for multi-angle machining without disassembling the workpiece, improving processing efficiency, and avoiding repeated clamping errors.

The limiting support column 5 and the clamping device 3 are both set on a mounting plate set on the upper rotating end of the electric rotating base 2, and the limiting support column 5 is located at the middle of the upper rotating end of the electric rotating base 2. The clamping device 3 is evenly distributed at the edge of the mounting plate. The bottom end of the limiting locking column 6 is threaded into the interior of the limiting support column 5. A flange 4 is set above the limiting support column 5, and the limiting locking column 6 is adapted to be inserted into the middle of the flange 4. A first screw-adjusting end 7 is fixedly installed at the bottom of the limiting locking column 6, and the first screw-adjusting end 7 lifts the bottom of the flange 4.
[0019] The first screw-adjustment end 7 is set in a hexagonal prism shape, which facilitates clamping and rotation adjustment by external wrenches and other equipment.
[0020] The clamping device 3 includes a pressing and fixing end 8, a sliding limit frame 9, a threaded adjusting rod 10, a screwing end 11, a limit support base 13, a fixing locking bolt 14, and a sliding clamping plate 15. The sliding clamping plate 15 is fixedly connected to the bottom of the sliding limit frame 9, and the bottom end of the sliding limit frame 9 is slidably clamped onto the limit support base 13. The threaded adjusting rod 10 is threaded through and inserted into the upper end of the sliding limit frame 9. The pressing and fixing end 8 is located at the front end of the threaded adjusting rod 10, and the front end of the threaded adjusting rod 10 is rotatably clamped into the inside of the pressing and fixing end 8. The screwing end 11 is fixedly connected to the end of the threaded adjusting rod 10 away from the pressing and fixing end 8. The bottom end of the sliding clamping plate 15 is in contact with the upper end surface of the limit support base 13.
