Description

Technical Field

[0001] The utility model relates to the technical field of milling machine processing, in particular to a milling machine clamping device for metal mold base processing. Background Technique

[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 process planes, grooves, and can also process various curved surfaces, gears, etc.

[0003] A mold base is the skeleton of a complete set of molds. The production of all mold parts needs to consider the structure of the mold base, and when processing the mold base, it is necessary to clamp the mold base to make the processing process more stable.

[0004] Most of the existing mold base clamping devices are non-adjustable during clamping and cannot adjust the device more conveniently. Therefore, when facing mold bases of different sizes, it is necessary to manually replace the fixture, which is not only time-consuming and laborious but also increases the investment cost.
