In the present invention, by making side, display portion before numerical control device for independently hermetically-sealed construction, prevent from immersing the dipstick portion, inner side from numerical control device such as the cutting fluid in console panel, suspention box.
First, use Fig. 1 that the first embodiment of numerical control device of the present invention, to have liquid crystal display is described.
In a side of console panel 1, numerical control device 2 is installed.Numerical control device 2 possesses control part casing 3 and display casing 4.Liquid crystal display 7 is received in this display casing 4.At the front side of this liquid crystal display 7 configuration touch panel 5.This touch panel 5 is fixed on frame 6.Front panel 8 is formed with frame 6 by this touch panel 5.In addition, Nonopaque type optical transparency plate can be used to replace transmission-type touch panel 5.In addition, suspention box can also be used to replace console panel 1.
Display casing 4 is formed the cable inserted for the signal cable being connected to liquid crystal display 7, feed cable 11 and passes through hole 12, but do not form heat transmission blow vent 9 as shown in Figure 3.
In addition, between the medial surface and the face (back side) of the liquid crystal display 7 opposed with this medial surface of display casing 4, heat exchange sheet 17 is configured.The heat produced by liquid crystal display 7 is dispelled the heat to display casing 4 by this heat exchange sheet 17.
On the other hand, the cable of display casing 4 is formed at by being blocked by occlusion component 18 with hole 12.This occlusion component 18 uses sealing bolt or sealant etc.In addition, as this occlusion component 18, impermeability connector also can be used to block cable by using hole 12.
As mentioned above, seal cavity 19 (the first seal cavity) in the display casing receiving liquid crystal display 7 is formed by front panel 8 (touch panel 5 and frame 6), display casing 4 and occlusion component 18.
On display casing 4, mount control part casing 3 on the face of the opposition side, side with configuration liquid crystal display 7.In this control part casing 3, receive printed circuit board 10, this printed circuit board 10 comprises the control circuit of the display and control carrying out liquid crystal display 7.In addition, this control part casing 3 is provided with the cooling fan 13 for being expelled to by the heat in control part casing 3 in console panel 1.In addition, by control part casing 3 with to be accommodated in control part casing 3 and the printed circuit board 10 comprising the circuit of the display control signal generating liquid crystal display forms control part.
Control part casing 3 is formed for make the cold air in console panel 1 enter air entry 14 in control part casing 3 and for being connected to the signal cable of printed circuit board 10, cable that feed cable 16 is inserted is by hole 15.Further, by driving cooling fan 13, the warm air in control part casing 3 is released into the outside (in console panel 1) of control part casing 3, and, the cold air in console panel 1 is entered in control part casing 3 from air entry 14.
As mentioned above; in the numerical control device 2 shown in Fig. 1; in order to protect the back side of touch panel 5 and liquid crystal display 7 from the impact such as cutting fluid or spraying; on display casing 4, only form as opening the cable inserted for the cable between connecting fluid crystal display 7 and printed circuit board 10 and pass through hole 12.Making following structure, by unique one being formed at the cable of the opening of display casing 4 by being blocked by occlusion component 18 or impermeability connector with hole 12, liquid crystal display 7 being accommodated in seal cavity 19 (the first seal cavity).
Further, the heat produced by liquid crystal display 7 can not be discharged into outside from the seal cavity 19 of this liquid crystal display 7 of storage by opening, but is dispelled the heat to display casing 4 by heat exchange sheet 17.
Blocking cable passes through can use sealing bolt, sealant, cable fixing head etc. with the occlusion component 18 in hole 12, and, impermeability connector can be used to replace this occlusion component.Pass through hole 12 by only forming as opening the cable inserted for the cable between connecting fluid crystal display 7 and printed circuit board 10 in this wise on display casing 4 and block this cable by with hole 12 by occlusion component (occlusion component 18), the back side hermetically protecting liquid crystal display 7 or touch panel of console panel 1 grade can not relied on.Even if cutting fluid or spraying are immersed in console panel 1, its impact also can be limited.
Then, use Fig. 2 that the second embodiment of numerical control device of the present invention, to have liquid crystal display is described.
The numerical control device of this second embodiment also possesses following structure on the numerical control device basis of above-mentioned first embodiment.
Control part casing 3 possesses the shield 22 of the runner for separating cooling fan 13 in inside.Control part casing 3 is formed and passes through hole 15 for the cable connecting the signal cable of printed circuit board 10 with external device (ED) (not shown), feed cable 16 is inserted.
Heat exchange sheet 20 is configured between the heating part of the printed circuit board 10 in control part casing 3 and shield 22.Further, the heat produced by printed circuit board 10 is dispelled the heat to shield 22 by this heat exchange sheet 20.
On the other hand, the cable of control part casing 3 is formed at by being blocked by occlusion component 21 with hole 15.This occlusion component 21 can use sealing bolt, sealant, cable fixing head, and, impermeability connector can be used to replace such occlusion component.
As mentioned above, form by shield 22 and occlusion component 21 (or impermeability connector) the second seal cavity receiving printed circuit board 10.
In this second embodiment, the functional parts such as control part (printed circuit board 10 and control part casing 3) also independently hermetically-sealed construction is made except the display portion (front panel 8, display casing 4 and liquid crystal display 7) of above-mentioned first embodiment (Fig. 1).By being configured for shield 22 and the impermeability connector of the runner separating cooling fan 13 or configuring occlusion component 21 on control part casing 3 around connector, form the seal cavity 23 (the second seal cavity) of storage printed circuit board 10, this printed circuit board 10 comprises the circuit generating display control signal.
According to the embodiment of the invention described above, can protect and easily be subject to the liquid crystal display of the impact brought by cutting fluid or spraying, the back side of touch panel, contribute to reducing fault, improving reliability.By making hermetically-sealed construction, likely bring impact by heat, but can eliminate by the decline of the power consumption of the LEDization with liquid crystal display 7 and by the countermeasure etc. that the heating from liquid crystal display 7 is dispelled the heat to display casing 4 by heat exchange sheet 17.In addition, divide each position of numerical control device 2 according to each function, form seal cavity independently, therefore display portion and control part can not be subject to the impact that brought by cutting fluid or spraying, contribute to reducing fault, improving reliability.
