[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. Lathes are generally equipped with protective devices to block waste chips and coolant generated during processing.

[0003] The prior art patent document with publication number CN220516199U discloses a CNC lathe with a dust collection structure, comprising a lathe base, a protective cover slidably connected to the top of the lathe base, a collection box clamped on the top of the protective cover, a drive motor is arranged on the side of the collection box, an output end of the drive motor is fixedly connected to a rotating rod through a coupling, a magnet is slidably connected to the outer surface of the rotating rod, a fixing plate and a limiting plate are respectively arranged at both ends of the magnet, the limiting plate is threadedly connected to the rotating rod, an end of the rotating rod away from the drive motor is fixedly connected to the collection box through a bearing seat, a dust suction port and an observation window are respectively provided on the sides of the protective cover, and a glass panel is installed in the observation window.

[0004] However, the above prior art still has the following deficiencies:

[0005] The protective cover in the above-mentioned prior art is provided with an observation window, in which a glass panel is fixed. When preventing waste chips from splashing, the waste chips will rub and collide with the glass panel. The friction between the waste chips and the glass panel will wear the surface of the glass panel, causing the tempered glass to become blurred and unable to see the processing status in the CNC lathe. The glass panel in the prior art is fixedly installed, so it is inconvenient to load and unload after wear. If the glass panel is not replaced in time, it will affect the staff's subsequent observation of the lathe processing status. Utility Model Content

[0006] The utility model aims to provide a lathe protection device for solving the technical problem of inconvenience in replacing the glass panel after it is worn and blurred in the prior art mentioned in the background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lathe protection device comprises a machine tool body and a protection door, which is slidably arranged on the top of the machine tool body, and is characterized in that: the protection door is provided with a window, a glass panel is detachably provided in the window, an adjustment groove is provided in the bottom wall of the window, an adjustment plate is rotatably provided in the adjustment groove, the upper end of the adjustment plate extends into the window and is provided with a groove for the lower end of the glass panel to be embedded, an installation frame is fixed in the window, and the glass panel can be abutted against the installation frame after rotation, a locking assembly for pressing the glass panel against the installation frame is installed on the top wall of the window, and a pop-up assembly is provided on the outer wall of the installation frame, one end of the pop-up assembly abuts against the glass panel, and the pop-up assembly can make the fixed assembly rotate relative to the adjustment groove through the glass panel and make the upper end of the glass panel located outside the window.

[0009] Working principle:

[0010] When removing the glass panel: adjust the locking assembly so that the locking assembly is separated from the glass panel and no longer presses the glass panel on the installation frame. Under the action of the pop-up assembly, the pop-up assembly pushes the upper end of the glass panel out of the window. At the same time, the pop-up assembly rotates the adjustment plate relative to the adjustment slot through the glass panel. At this time, the glass panel is tilted on the adjustment plate and the upper end is located outside the window, which is convenient for the operator to replace the glass panel.
