[0002] Milling machine is a widely used machine tool. It can process planes (horizontal and vertical surfaces), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used for machining the surface of rotating bodies, inner holes and cutting.

[0003] When the milling machine is running, the parts need to be fixed by a clamping device to improve the stability of the material during processing. The existing clamping devices are usually divided into manual and automatic. The manual labor intensity is too high, while the automatic clamping device can only clamp and fix the parts from both sides, and the fixing effect is general, which ultimately leads to the overall processing efficiency and precision of the workpiece are not high. Therefore, in view of the above situation, it is urgent to develop an automatic clamping device for milling machines to overcome the shortcomings in current practical applications.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] When the device is running, the part is placed on the support table, and the multi-directional synchronous clamping assembly is arranged around the outside of the part. The multi-directional synchronous clamping assembly can first complete the clamping of the part from the front and back sides, and then further clamp the part from the left and right sides, so as to realize the positioning and horizontal fixation of the part. During the operation of the multi-directional synchronous clamping assembly, the inductive extrusion assembly can also be driven by the pressure transmission control assembly. The inductive extrusion assembly cooperates with the support table to fix the part longitudinally, thereby ensuring the stability of the part during processing, and the automatic avoidance unit can also drive the multi-directional synchronous clamping assembly to realize the rotation of part of the inductive extrusion assembly, so that The inductive extrusion component is separated from the surface of the part, thereby completing the avoidance of the milling cutter, thereby realizing comprehensive processing of the part.
