Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, and more specifically, to a clamping device for a milling machine. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the main motion is the rotation of the milling cutter, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. When the milling machine processes the workpiece, it needs to use a clamping device to clamp the workpiece;

[0003] At present, after the workpiece is clamped on the vertical lifting table milling machine, the workpiece is fixed on the clamping platform, and the cutting position can only be controlled by moving the spindle in the x, y and z directions. When the spindle stroke is limited, the surface of the workpiece cannot be accurately cut, resulting in incomplete workpiece processing and affecting workpiece processing efficiency;
