When the shields 21 are in the deployed state, each The first interlocking portion 511 abuts against the respective second interlocking portion 512.

Referring to FIGS. 1, 5, and 9, the operation principle of the process of changing the shields 21 from the closed state shown in FIG. 5 to the expanded state of FIG. 1 is described below, and then the process of changing from the expanded state to the closed state is explained. The operation principle of the above, and for convenience of description, the shields 21 shown in FIG. 1 are defined in order from right to left as a first shield 21, a second shield 21, a third shield 21, and A fourth shield 21, and the left and right sides in the following description represent the left and right sides shown in FIG. 5, respectively.

When the shroud 21 is to be changed from the closed state to the unfolded state, the fourth shroud 21 needs to be operated to slide to the left along the feed axis X, which can drive the fourth shroud to be connected to the fourth shroud The first interlocking portion 511 on 21 abuts on the right side of the second interlocking portion 512 connected to the third shield 21 (see FIGS. 8 and 9), so that the third shield 21 is driven to move to the left . Similarly, the first linkage portion 511 connected to the third shield 21 can also drive the second shield 21 to move to the left. When the first linking portion 511 connected to the second shield 21 abuts on the right side of the second linking portion 512 connected to the first shield 21 (see FIG. 8 ), the deployed position is reached.

When changing the shield 21 from the expanded state to the closed state, it is necessary to first operate the fourth shield 21 to slide to the right along the feed axis X, and the fourth shield 21 The reinforcing plate portion 214 is driven against the left side of the reinforcing plate portion 214 of the third shield 21, so that the third shield 21 is driven to slide to the right. Similarly, the reinforcing plate portion 214 of the third shield 21 abuts against the left side of the reinforcing plate portion 214 of the second shield 21, and drives the second shield 21 to slide to the right. When the reinforcing plate portion 214 of the second shield 21 abuts the left side of the reinforcing plate portion 214 of the first shield 21, the closed position is reached.

Referring to FIGS. 2, 5 and 6, during the foregoing operation, since each first sliding member 312 and the respective first guide rail 311 can slide relative to each other along the extension direction of the axis L when sliding relative to each other, and each second When the sliding members 322 and the respective second guide rails 321 slide relative to each other, they can be positioned along the extending direction of the axis L, so that the shields 21 can be positioned relative to each other along the extending direction of the axis L during the relative sliding process. . By setting the upper guide wheel group 42 and the guide wheel group 43, the shields 21 can slide more smoothly.

In this way, a machine tool cutter (not shown) can be installed on a side adjacent to the first shield 21, and a workbench (not shown) can be connected to the fourth shield 21 when the When the working table approaches or moves away from the machine tool along the feed axis X, the fourth shield 21, the third shield 21, and the second shield 21 can slide along the feed axis X The rail unit 12 is constantly shielded, and the first plate portion 211, the second plate portion 212, and the third plate portion 213 of each shield 21 can surround a portion of the workbench, thus avoiding the production process Debris or dust falls on the rail unit 12.

In addition, in other embodiments, a telescopic protective cover for another machine may also be provided on the side of the worktable opposite to the tooling machine tool to avoid debris or dust from the worktable opposite to the machine tool One side of the tool falls onto the rail unit 12.

It is worth mentioning that, in this embodiment, the cover unit 2 includes four shields 21, however, in other embodiments, the cover unit 2 may also include only two shields 21 or three One shield 21 or the cover unit 2 may include more than five shields 21. In the embodiments with different numbers of shields 21, the number of the first sliding modules 31 and the interlocking modules 51 are one less than the number of the shields 21, and are respectively disposed on adjacent Between the two shields 21.

In summary, by providing the sliding unit 3, the shields 21 can be operated to overlap each other along the axis L or parallel to each other along the feed axis X, so they can move with the table Since the rail unit 12 is shielded, debris or dust generated during the process can be prevented from falling on the rail unit 12.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
