[0002] Vertical turret milling machine is also called rocker milling machine, universal milling machine, is a kind of turret milling machine, belongs to the category of milling machine. The difference between vertical turret milling machine and turret milling machine is that its spindle can only feed vertically, and the direction of spindle travel forms a 90-degree angle with the plane of the worktable, so it is called vertical turret milling machine. Vertical turret milling machine can be widely used for processing planes, inclined planes of any angle, milling keyways, grooves, and can also turn, ream, and bore holes. Its milling head can rotate 90 degrees to the left and right, 45 degrees to the front and back, and the ram can rotate 360 ​​degrees horizontally. The spindle has a large speed range and high speed. The spindle sleeve can be fed with a fixed stroke, and an overload protection device is provided. However, some existing vertical turret milling machines lack a protective structure, and a large amount of splashing waste chips are usually generated during the processing of the workpiece, which may cause harm to the body of the staff on the front side of the milling machine. Therefore, those skilled in the art provide a vertical turret milling machine protection mechanism to solve the problems raised in the above background technology. Utility Model Content
