Description

Technical Field

[0001] This utility model belongs to the technical field of vertical machining centers and their accessories, and in particular relates to a moving protective device for vertical machining centers. Background Technology

[0002] A vertical machining center is a CNC machine tool with a vertically set spindle. It is mainly used for machining tasks such as drilling, milling, and boring, and is particularly suitable for precision machining of small and medium-sized parts such as discs, sleeves, and plates. The protective device of a vertical machining center is one of its most important accessories. It is mainly divided into safety doors for equipment safety protection and protective covers for the machining process. The protective cover is installed on the machining axis to shield and protect the cutting tools and workpieces.

[0003] Chinese patent application CN223325997U discloses a protective device for a vertical machining center, including a protective cover, a fixed base on the left side of the rear end of the protective cover, and mounting slots on both the upper and lower sides of the rear end of the fixed base. The device also includes a fixing mechanism. The fixing mechanism includes a mounting rod, transmission arms, and clamping plates. The mounting rod is rotatably connected to the left and right sides inside the fixed base. Transmission arms are respectively located on the upper and lower sides of the outer arc surface of the mounting rod, and are respectively located inside longitudinally adjacent mounting slots. Clamping plates are provided at the rear ends of each transmission arm. This protective device for a vertical machining center replaces the traditional method of installing and fixing the protective device with screws, improving the stability of the protective device, ensuring its protective effect, reducing the risk of injury to workers, and further ensuring operational safety.

[0004] The aforementioned protective device for a vertical machining center has a square protective cover that is directly mounted on the machine tool. A fixed base is located at the rear of the cover, connecting to a mounting assembly via a mounting slot. Opening the cover requires pushing it outwards, during which the cover rotates around the mounting assembly. No obstructions are allowed within this rotational range to prevent the cover from being blocked. This results in a large working space required to open the cover. Furthermore, the inner side of the cover is the machining area of ​​the machining center, where significant amounts of splashed liquid and workpiece debris are generated during machining. These waste liquids and debris collide with the inner wall of the cover, affecting the operator's ability to observe the machining process through the viewing window. Therefore, we provide a moving protective device for a vertical machining center to address these problems. Utility Model Content

[0026] Example 1

[0027] Please see Figure 1-3 This utility model is a moving protective device for a vertical machining center, including a protective plate 1, a protective plate 2, and a protective plate 3. The protective plates 1, 2, and 3 are interlocked, which greatly saves space and allows for lateral opening, requiring less working space when opening. The protective plates 2 and 3 can be moved to different positions by electric push rods 102 and 202 to achieve the protective effect of designated areas.

[0028] Specifically, the protective plate 1 has a groove 101 inside, the protective plate 2 has a groove 201 inside, the protective plate 1 is slidably connected to the outer wall of the protective plate 2 through the groove 101, and the protective plate 2 is slidably connected to the outer wall of the protective plate 3 through the groove 201.

[0029] Furthermore, two electric push rods 102 and 202 are provided respectively. The two electric push rods 102 are fixedly installed at both ends inside the plate groove 101 by a fixing bracket 102a, and the telescopic end of the electric push rod 102 is connected to the left side wall of the protective plate 2. This achieves the effect that when the electric push rod 102 is working, it pushes the protective plate 2 to move in the protective plate 1.

[0030] The electric push rod 202 is fixedly installed at both ends inside the plate groove 201, and the telescopic end of the electric push rod 202 is connected to the left side wall of the protective plate 3; thus, when the electric push rod 202 is working, it pushes the protective plate 3 to move in the protective plate 22.
