Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a milling fixture. Background Technology

[0002] In existing technology, milling is a machining method that uses a milling cutter as a cutting tool to process the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines, and lever milling machines. Milling machine tools can be horizontal or vertical milling machines, as well as large gantry milling machines. These machine tools can be ordinary machine tools or CNC machine tools. The cutting process uses a rotating milling cutter as the cutting tool. Milling is generally performed on milling machines or boring machines and is suitable for machining planes, grooves, various shaped surfaces, and special shapes of molds. When performing milling operations on a workpiece, it needs to be clamped using a fixture. Existing fixtures generally consist of placing the workpiece between two clamping plates, and clamping the workpiece by bringing the two clamping plates close together.
