Description

Technical Field

[0001] The utility model relates to the technical field of clamping structures, in particular to a clamping structure for steel flange processing. Background Technique

[0002] A clamping structure is a device used to fix workpieces in the field of machining. Its basic function is to keep the position of the workpiece stable during the machining process to prevent the machining accuracy from being affected by vibration or movement.

[0003] Common clamping structures generally use a pressure screw to drive a clamping block to move, and the steel flange is squeezed by the clamping block to clamp it.

[0004] However, since there are many specifications of steel flanges and the sizes of different specifications of steel flanges are different, when drilling a steel flange, it is necessary to first clamp the steel flange and install a corresponding clamping structure on its outer ring. When clamping other specifications of steel flanges subsequently, it is necessary to disassemble the clamping structure on the surface of the processing table and reinstall the corresponding clamping structure, which takes up most of the time for steel flange processing, and the operation is complex, and the steel flange cannot be clamped quickly.
