In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] like Figure 1-Figure 3 As shown, this embodiment provides a CNC machine tool with a shield, which includes a machine base (not shown in the figure), a crossbeam 10, a spindle mechanism 20 and a follower shield assembly, wherein a protective enclosure (not shown in the figure) arranged around the periphery of the processing area is provided on the machine base, the crossbeam 10 can slide relative to the machine base along a first horizontal direction and a second horizontal direction, the first direction and the second direction are perpendicular to each other, and the spindle mechanism 20 is slidably mounted on the crossbeam 10 along a vertical direction. The follower shield assembly is arranged in the interval area between the spindle mechanism 20 and the protective enclosure, the spindle mechanism 20 is vertically penetrated through the follower shield assembly, the follower shield assembly is at least covered on the top of the processing area, the follower shield assembly is connected to the crossbeam 10 and the protective enclosure, slides horizontally with the crossbeam 10, and the follower shield assembly can be extended and retracted along the first direction and the second direction. The first direction is the X direction in the figure, and the second direction is the Y direction in the figure.

[0039] Specifically, the CNC machine tool with a guard provided in this embodiment, on the one hand, uses a protective enclosure to enclose the periphery of the processing area, and on the other hand, uses a follower guard assembly to at least enclose the top of the processing area; the protective enclosure and the follower guard assembly cooperate with each other to fully isolate the processing area from the external environment, thereby protecting the processing area. The follower guard assembly can be extended and retracted in the first direction and the second direction with the horizontal sliding of the crossbeam 10, so the follower guard assembly does not need to be arranged on the top of the machine base but on the periphery of the spindle component, and the staff does not need to climb on the top of the machine to install the guard, which is less difficult to install and less costly, and the guard does not need to cover the entire spindle mechanism 20, so that the longitudinal space occupied by the machine is also smaller.

[0040] For example, Figure 1 and Figure 2 As shown, the follower shield assembly includes a first shield 1, a second shield 2 and a third shield 3. Among them, one end of the first shield 1 is connected to the crossbeam 10, and the other end is connected to the protective enclosure, and the first shield 1 can be extended and retracted in the first direction; the second shield 2 is arranged at one end of the spindle mechanism 20 in the second direction, one end of the second shield 2 is connected to the crossbeam 10, and the other end is connected to the protective enclosure, and the second shield 2 can be extended and retracted in the second direction; the third shield 3 is arranged at the other end of the spindle mechanism 20 in the second direction, one end of the third shield 3 is connected to the crossbeam 10, and the other end is connected to the protective enclosure, and the third shield 3 can be extended and retracted in the second direction.

[0041] Specifically, when the beam 10 moves horizontally along the first direction, the first shield 1 is stretched or compressed accordingly; when the beam 10 moves horizontally along the second direction, one of the second shield 2 and the third shield 3 is stretched accordingly, and the other of the second shield 2 and the third shield 3 is compressed accordingly.

[0042] For example, Figure 1 and Figure 2 As shown, the cross beam 10 is provided with a shield slide rail 7 extending along the first direction, and a shield slider 8 is slidably provided on the shield slide rail 7. The follower shield assembly also includes a shield mounting frame 6, and the shield mounting frame 6 is connected to the shield slider 8. The ends of the first shield 1, the second shield 2 and the third shield 3 connected to the cross beam 10 are all connected to the shield mounting frame 6.

[0043] Furthermore, the ends of the first shield 1, the second shield 2 and the third shield 3 away from the cross beam 10 are fixedly connected to the corresponding protective enclosures. When the cross beam 10 moves horizontally along the first direction, the shield mounting frame 6 slides along the shield slide rail 7, and the positions and postures of the second shield 2 and the third shield 3 remain unchanged.

[0044] For example, Figure 1 and Figure 2As shown, the CNC machine tool further includes a first slot plate 4, which extends along the second direction and is installed on the inner side of the protective enclosure, and one end of the second shield 2 in the first direction extends into the slot of the first slot plate 4 and is slidably connected to the first slot plate 4 in the second direction. The first slot plate 4 can support the second shield 2 and provide a guiding function when the second shield 2 is extended and retracted along the second direction.

[0045] For example, Figure 1 and Figure 2 As shown, the CNC machine tool further includes a second slot plate 5, which extends along the second direction and is installed on the inner side of the protective enclosure, and one end of the first shield 1 in the first direction extends into the slot of the second slot plate 5 and is slidably connected with the second slot plate 5 along the second direction. The second slot plate 5 can support the first shield 1 and provide a guiding function when the first shield 1 moves along the second direction with the crossbeam 10.

[0046] For example, Figure 1 and Figure 2 As shown, one end of the third shield 3 in the first direction extends into the slot of the second slot plate 5 and is connected to the second slot plate 5, specifically a sliding connection, that is, the second slot plate 5 can also support the third shield 3 at the same time, and the end of the third shield 3 close to the first shield 1 never separates from the second slot plate 5.

[0047] For example, Figure 1 and Figure 2 As shown, the second shield 2 is configured as an inverted L-shaped structure, and the second shield 2 includes a first horizontal portion and a first vertical portion connected to each other, the first horizontal portion is used to shield the top of the processing area, and the first vertical portion is used to shield the periphery of the processing area.

[0048] For example, Figure 1 and Figure 2 As shown, the third shield 3 is configured as an inverted L-shaped structure, and the third shield 3 includes a second horizontal portion and a second vertical portion connected to each other, the second horizontal portion is used to shield the top of the processing area, and the second vertical portion is used to shield the periphery of the processing area.

[0049] For example, Figure 1 and Figure 2 As shown, the first protective cover 1 is configured as an accordion protective cover.

[0050] For example, Figure 1 and Figure 2 As shown, the second protective cover 2 is configured as an accordion protective cover.

[0051] For example, Figure 1 and Figure 2 As shown, the third protective cover 3 is configured as an accordion protective cover.

[0052] For example, Figure 1-Figure 3As shown, two anti-sway components 9 are installed on the crossbeam 10, and the two anti-sway components 9 are respectively arranged corresponding to the second shield 2 and the third shield 3. The anti-sway components 9 are pressed against one end of the second shield 2 or the third shield 3 connected to the shield mounting frame 6 along the second direction to prevent the second shield 2 and the third shield 3 from shaking when they are extended or retracted, thereby improving stability.

[0053] For example, Figure 3 As shown, the anti-sway assembly 9 includes an anti-sway mounting plate 91 and an anti-sway guide wheel 92. The anti-sway mounting plate 91 is mounted on the cross beam 10. The anti-sway guide wheel 92 is rotatably arranged on the anti-sway mounting plate 91 around a vertical axis. The anti-sway guide wheel 92 is pressed against one end of the second guard 2 or the third guard 3 connected to the guard mounting frame 6. The anti-sway guide wheel 92 is arranged to provide a guiding effect for the movement of the second guard 2 and the third guard 3 along the first direction.

[0054] Exemplarily, the spindle mechanism 20 includes a ram and a tool. The ram is slidably mounted on the beam 10 along a vertical direction. The tool is mounted on the bottom end of the ram. The tool is always located below the follower shield assembly.
