Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a protective structure for CNC machine tools used in metal parts processing. Background Technology

[0002] In the field of metal parts processing, CNC machine tools are widely used due to their high precision and efficiency. CNC machine tools process metal parts within a machining area, generating a large amount of chips and splashing coolant, requiring a protective structure to isolate the machining area. Protective covers are a common form of protection for machine tools.

[0003] To facilitate workpiece installation, protective covers on machine tools can be designed to be detachable. Detachable protective covers are typically installed using bolts. Since the bolts are separate components, they need to be handled during installation and removal, impacting work efficiency and increasing the risk of loss. Furthermore, to facilitate operator observation of the metal workpiece machining process, protective covers are usually equipped with observation windows. However, during machining, cutting fluid and chips can easily adhere to these windows, obstructing visibility. Utility Model Content

An observation window is provided on the protective cover. A second slider, slidably connected to a second slide groove of the machine tool, is located on the front of the protective cover. A first positioning bolt and a limiting seat for limiting the first positioning bolt are provided on the outer side of the second slider. A first positioning hole is provided inside the second slide groove. The first positioning bolt passes through the protective cover and the second slider sequentially and is inserted into the first positioning hole to form a positioning connection between the protective cover and the machine tool. A limiting plate is provided on the screw of the first positioning bolt, and the limiting seat is used to limit the limiting plate to prevent the screw from dislodging from the protective cover.

[0009] Preferably, the protective cover is provided with a lever for moving the cleaning brush. The lever is slidably connected to the guide rod. The upper part of the lever is connected to the protective cover through an elastic element. The lever is connected to the cleaning brush through a connecting rod. The elastic element has a contraction tendency so that the cleaning brush stays above the observation window.

[0010] Preferably, one end of the connecting rod is provided with a mounting base, the top of the cleaning brush is provided with a slot that matches the mounting base, and the side of the cleaning brush is provided with a second positioning bolt for positioning and connecting the mounting base and the cleaning brush.

The processing area of ​​the machine tool 1 is located between the first slide groove 101 and the second slide groove 102. The protective cover 2 can shield the processing area of ​​the machine tool 1, isolating the processing area from the outside when the machine tool 1 is processing metal parts, thus achieving a protective function.

[0026] One end of the first slide 101 and the second slide 102 is not infinitely movable, and the protective cover 2 can be completely removed from one side of the machine tool 1, making it convenient to completely remove the protective cover 2 from the machine tool 1.

[0027] The protective cover 2 is provided with a first positioning bolt 6 on the outside of the second slider 22, and a first positioning hole is provided inside the second slide groove 102. The second slider 22 is provided with a threaded hole, and the first positioning bolt 6 matches the threaded hole of the second slider 22. The first positioning bolt 6 can pass through the protective cover 2 and the second slider 22 in sequence and be inserted into the first positioning hole of the second slide groove 102 to form a positioning between the protective cover 2 and the machine tool 1.

[0028] The number of first positioning bolts 6 is at least one; in this embodiment, the number of first positioning bolts 6 is two. The first positioning bolts 6 are located on the front of the machine tool 1, making it convenient for operators to operate the first positioning bolts 6 and to facilitate the positioning and loosening of the protective cover 2.
