[0002] A milling machine is a machine tool that uses a milling cutter to mill workpieces. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex surfaces. They are more efficient than planers and are widely used in machinery manufacturing and repair departments.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: before the milling cutter performs specific processing on the workpiece, the workpiece needs to be positioned using a fixture on the milling machine. The current milling machine fixture usually adjusts the position of the workpiece mechanically and can usually only perform a single adjustment (translation, lifting, rotation, etc.), but these position adjustment operations cannot be performed synchronously, resulting in the workpiece position adjustment being not flexible and convenient, and not being convenient for the milling cutter to achieve more complex processing methods.

[0004] To this end, we proposed a new type of milling machine fixture to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a novel milling machine fixture, which allows the workpiece to rotate while translating, making the adjustment of the workpiece position more flexible and convenient, thereby realizing more complex processing methods on the milling machine and effectively solving the problems in the background technology.

[0010] As a preferred embodiment, the screw rod and the sliding rod are both arranged horizontally, wherein both ends of the screw rod are rotatably connected to the bottom support; so that the screw rod can operate stably when driven by the first servo motor, and both the first servo motor and the second servo motor need to be powered by external power facilities.

[0011] As a preferred embodiment, a positioning groove is formed at the center of the bottom wall of the clamping seat, and the second servo motor is vertically installed on the top wall of the positioning groove; so that the second servo motor structure remains stable and can be hidden in the positioning groove.
