Description

Technical Field

[0001] The utility model relates to the field of milling machines, and particularly relates to a clamping device for a milling machine. Background Art

[0002] A milling machine mainly refers to a machine tool that processes various surfaces of a workpiece with a milling cutter. Usually, the rotational movement of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement. It can machine planes, grooves, and can also machine various curved surfaces, gears, etc. A milling machine is a machine tool that mills a workpiece with a milling cutter. In addition to milling planes, grooves, gear teeth, threads, and spline shafts, a milling machine can also machine relatively complex profiles, with higher efficiency than a planer, and is widely used in the machinery manufacturing and repair departments.

[0003] The clamping devices for milling machines on the market can effectively fix the parts during the process of part processing, and then process them through the milling machine. However, the traditional clamping devices for milling machines cannot turn over the parts after fixing the parts.
