Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of signal detecting switching device for numerically-controlled machine tool, including shell 1, the top two of shell 1
Side is mounted by means of screws with two support plates 2, and support plate 2 is mounted by means of screws with first between mutually close side
Fixed plate 9 and the second fixed plate 14, the first fixed plate 9 are located at the top of the second fixed plate 14, and 9 activity of the first fixed plate is equipped with
Two guide rods 10, one end of guide rod 10 extends to the lower section of the first fixed plate 9, and one end of guide rod 10 is welded with first jointly and connects
Touch panel 11, the top movable of shell 1 are equipped with the mandril 5 being vertically arranged, and mandril 5 is located between two support plates 2, mandril 5
The body of rod is welded with block 4, and mandril 5 is arranged with the first spring 3, and one end of the first spring 3 and the top of block 4 are welded, the first bullet
The other end of spring 3 is welded with the second contact plate 16, and the second contact plate 16 is set on mandril 5, and the second contact plate 16 and mandril 5
It does not contact.
In the present embodiment, in use, an oil pipe 7 is connect with peripheral hardware hydraulic mechanism, another oil pipe 7 and lathe oil circuit connect
It connects, and two first contact electrodes 12 and two third contact electrodes 15 are connected by the machine tool controller of conducting wire and peripheral hardware,
And the hydraulic circuit of lathe has hydraulic-driven range, can complete manufacturing procedure as long as the lathe in this hydraulic range,
Therefore when oil enters shell 1, as long as oil pressure is more than that lathe runs minimum oil pressure, that is, second spring 6 reaches surrender
