The semicircular track is installed on the base, and the semicircular track is located below the main disk. The movable table is slidably connected to the semicircular track, and the first protective plate is vertically installed on the movable table through a cross bar. A handle is installed on the first protective plate, and an adjusting rod is horizontally slidably connected to the handle. A guide seat is installed on the cross bar, and a push rod is horizontally slidably connected to the guide seat, one end of the push rod is connected to a friction pad, and the friction pad can abut against the outer side surface of the semicircular track, and the other end of the push rod is connected to the adjusting rod through a wire rope, and a supporting spring is provided between the middle part of the push rod and the guide seat.

[0006] A guide block is also installed on the first protective plate, a guide rail is horizontally slidably connected to the guide block, a second protective plate is connected to the guide rail, and a screw is threadedly connected to the guide block.

[0007] The screw is a hand-tightened part.

[0008] The first protective plate and the second protective plate are both made of steel plates.

[0009] The height of the first protective plate is greater than the height of the second protective plate.

[0010] Compared with the prior art, the CNC machine tool with auxiliary mechanism has the following advantages:

[0011] In the utility model, the first protective plate and the second protective plate cooperate with each other, so that the protective height can be changed as needed, and the protective position can also be conveniently adjusted. Therefore, when a cylindrical workpiece is accidentally disconnected and thrown out during processing, the operator can use the protective plate for protection, which greatly improves the safety of the operation.

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-Figure 3As shown, the CNC machine tool with auxiliary mechanism comprises a base 1, on which a main disk 2 for clamping a workpiece is rotatably arranged. In this embodiment, the CNC machine tool refers to a CNC double-axis vertical lathe; the auxiliary mechanism is arranged on the base 1, and the auxiliary mechanism comprises a semicircular track 6, a movable platform 11, and a first protective plate 5. The semicircular track 6 is installed on the base 1, and the semicircular track 6 is located below the main disk 2. The movable platform 11 is slidably connected to the semicircular track 6. The first protective plate 5 is vertically installed on the movable platform 11 through a cross bar 10. A handle 4 is installed on the first protective plate 5, and a regulating rod 12 is horizontally slidably connected to the handle 4. A guide seat 16 is provided, on which a push rod 15 is horizontally slidably connected, one end of the push rod 15 is connected to a friction pad 14, and the friction pad 14 can abut against the outer side surface of the semicircular track 6, and the other end of the push rod 15 is connected to the regulating rod 12 through a wire rope 13, and a supporting spring 17 is provided between the middle part of the push rod 15 and the guide seat 16; with this structure, the handle 4 is held, and at the same time, the regulating rod 12 is pulled outward to disengage the friction pad 14 from the outer side surface of the semicircular track 6, and it can be adjusted to a desired position, and the regulating rod 12 is released. Under the action of the supporting spring 17, the friction pad 14 abuts against the outer side surface of the semicircular track 6, that is, its position is locked.

[0018] A guide block 8 is also installed on the first protective plate 5, and a guide rail 9 is horizontally slidably connected to the guide block 8. The second protective plate 3 is connected to the guide rail 9, and a screw 7 is threadedly connected to the guide block 8. With this structure, the entire protective height can be changed by cooperating with the second protective plate 3 and the first protective plate 5, and the protective height can be above the operator's chest and below the head.

[0019] The screw 7 is a hand-tightened part.

[0020] The first protective plate 5 and the second protective plate 3 are both made of steel plates.
