Technical Field

[0001] This utility model relates to the field of milling machine fixture technology, specifically to a milling machine fixture. Background Technology

[0002] Milling machine fixtures, as a type of machining tool, are widely used in various manufacturing industries, especially in metal cutting, precision machining, and large-scale production, where they play a crucial role. Their basic function is to firmly fix the workpiece on the milling machine worktable, ensuring the stability of the workpiece during machining and preventing a decrease in machining accuracy due to workpiece loosening or movement.

[0003] However, most existing milling machine fixture designs adopt the method of directly clamping the workpiece, usually relying on manually placing the workpiece into the fixture for clamping. Although this method can meet some conventional machining needs, there are still certain safety hazards in fixtures driven by electric or pneumatic power. During operation, the operator needs to manually place the workpiece directly into the clamping area, which makes the operator's hands vulnerable to the fixture and may even lead to accidents. Utility Model Content
