[0036] When the vertical assembly 4 keeps vertical with the machine body 1, the axis of the double-layer ring-shaped piece 431 is just collinear with the cutting axis.

[0037] It should be noted that the rotating connection mode of the cutting head 3 and the rotating arm 41 adopts a high-precision bearing, which ensures the stability and precision of the rotating arm 41 during rotation, and further improves the accuracy of vertical calibration of the electrode wire 32.

[0038] In the embodiment, the cutting head 3 comprises a mounting block 31, an adjusting disc 33 and the electrode wire 32, the cutting head 3 is rotatably connected with one side of the rotating arm 41, and the adjusting disc 33 is arranged on one side of the mounting block 31 and used for adjusting the perpendicularity of the electrode wire 32.

[0039] It should be noted that the rotating arm 41 is rotatably connected with the cutting head 3, when vertical calibration is needed, the rotating arm 41 is directly rotated to make the calibration assembly 43 detect, and when the line cutting works, the calibration assembly 43 can be quickly separated by rotating, so that the flexibility and practicability of the equipment are improved.

[0040] In the embodiment, one side of the rotating arm 41 close to the bottom surface of the cutting head 3 is provided with a magnetic surface 411, and the magnetic surface 411 can be magnetically attached to the bottom of the cutting arm 2.

[0041] It should be noted that the magnetic surface 411 and the cutting arm 2 should be guaranteed to be easily separated by the operator rotating by hand, and the operator should not easily fall in the natural state.

[0042] In this embodiment, the rotation angle range of the rotating arm 41 is that the magnetic surface 411 and the bottom of the cutting arm 2 are magnetically adhered to the rotating arm 41 and the body 1 is perpendicular.

[0043] It should be noted that the angle range is limited, which can quickly move the calibration assembly 43 to the detection position by rotating the rotating arm 41, and the use is more convenient.

[0044] In this embodiment, the sliding member is provided with a screw 421 on one side.

[0045] It should be noted that the screw 421 can adjust the sliding damping size between the first sliding member 42 and the rotating arm 41, and improve the stability of the first sliding assembly on the rotating arm 41.

[0046] In this embodiment, the size of the fan-shaped opening 4311 can ensure that the electrode wire 32 can pass easily, and also ensure the stable sliding of the second sliding member 432; when the rotating arm 41 is perpendicular to the body 1, the double-layer ring member 431 and the adjusting bolt 433 are parallel to the body 1, and the adjusting bolt 433 is perpendicular to the second sliding member 432.

[0051] Working principle: when the electrode wire 32 is vertically calibrated by using the wire cutting device convenient for vertical calibration, first, the calibration assembly 43 is adjusted to be parallel to the fuselage 1 by rotating the rotating arm 41, at this time, the axis of the double-layer ring-shaped part 431 is just collinear with the cutting axis, then, according to the actual situation and processing requirements of the workpiece, the relative position between the detection round head 4331 and the electrode wire 32 is accurately adjusted by adjusting the position of the first sliding part 42 on the rotating arm 41 and the position of the second sliding part 432 on the double-layer ring-shaped part 431, combined with adjusting the threaded connection of the adjusting bolt 433. In the adjustment process, the spark size of the detection round head 4331 can be observed to judge whether the verticality of the electrode wire 32 meets the requirements. When the spark size of the detection round head 4331 is always unchanged during the movement of the first sliding part 42 and the movement of the second sliding part 432, the electrode wire 32 is in a vertical state, and when not in use, the magnetic attraction surface 411 is magnetically attracted and attached to the bottom of the cutting arm 2, and at the same time, it will not hinder the work of wire cutting.
