The specific embodiment
See also Fig. 1 (a), this is the embodiment one of this utility model intelligence electric welder's helmet, and it comprises:
Rotating shaft 22, be fixed in rotationally on the face shield 16 with two fixing points 221,222, rotating shaft 22 near and be parallel to a limit of the perspective window 161 of face shield 16, an end of rotating shaft 22 connects the center 231 of a disk 23, the radius of disk 23 is greater than the section radius of rotating shaft 22;
Operating spring 26 connects the metallic core 27 and second fixture 232;
Back-moving spring 25, connect first fixture 24 and second fixture 232, the stiffness factor of operating spring 26 is greater than the stiffness factor of back-moving spring 25, and promptly both compare, operating spring 26 relatively is not easy to stretch or compression, and back-moving spring 25 stretches or compression than being easier to;
Intelligent electric welder's helmet shown in Fig. 1 (a) after the energising of the two ends 273,274 of second coil, the second coil 272 formation magnetic field that promptly switch on, by second coil 272 around metallic core 27 slide pulling action spring 26 along sliding channel 271.Operating spring 26 spurs second fixture 232 again, drives disk 23 231 rotations along the center of circle, and stretching back-moving spring 25.Disk 23 is fixed in an end of rotating shaft 22, thereby driven rotary axle 22 rotates.Optical filter 21 is fixed in rotating shaft 22, therefore also rotates thereupon, hides the perspective window 161 of face shield 16.
Intelligent electric welder's helmet shown in Fig. 1 (a) is after 273,274 outages of the two ends of second coil, and second coil 272 promptly loses magnetic field, and back-moving spring 25 shrinks, and spurs second fixture 232 to 24 motions of first fixture, drives disk 23 and rotates along the center of circle.Disk 23 is fixed in an end of rotating shaft 22, thereby driven rotary axle 22 rotates.Optical filter 21 is fixed in rotating shaft 22, therefore also rotates thereupon, leaves the perspective window 161 of face shield 16.
Two ends 273,274 energisings, the outage of controlling second coil have two kinds of schemes.First kind of scheme sees also Fig. 1 (b), and face shield 16 also comprises a closed conductor 14, and closed conductor 14 is positioned at outside the face shield 16.Electric welding machine 11 external 220V or the 10 back outputs of 380V alternating current power supply reduce voltage, improve the power supply of electric current, and the two ends of out-put supply connect electrode holders 12 and metal works 15 respectively by two cables 111,112.Electrode holders 12 connect and clamping welding rod 13.It is close or pass or pass and around this closure conductor 14 to connect the cable 112 of electric welding machine 11 and metal works 15.See also Fig. 1 (c), being wound with first coil, 141, the first coils 141 on the closed conductor 14 has the two ends 142,143 of two ends 142,143, the first coils 141 to connect the two ends 273,274 of second coil 272 respectively.
In the system shown in Fig. 1 (b), when producing electric arc between welding rod 13 and the workpiece 15, cable 112 passes through alternating current.Because cable 112 is close or pass or pass and around closed conductor 14, therefore produce magnetic field on the closed conductor 14.First coil 141 that is wound on the closed conductor 14 produces faradic current thereupon, two ends 142,143 energisings of first coil, two ends 273,274 energisings of second coil.
In the system shown in Fig. 1 (b), when the arc welding operation stopped, cable 112 no longer includes electric current to be passed through, and therefore no longer included magnetic field on the closed conductor 14.。First coil 141 that is wound on the closed conductor 14 also no longer includes faradic current, two ends 142,143 outages of first coil, two ends 273,274 outages of second coil.
Therefore, the intelligent electric welder's helmet shown in complex chart 1 (a), Fig. 1 (b), when the arc welding operation begins, two ends 273,274 energisings of second coil, optical filter 21 rotates and hides the perspective window 161 of face shield 16.When the arc welding operation stops, two ends 273,274 outages of second coil, optical filter 21 rotates and leaves the perspective window 161 of face shield 16.
The two ends 273,274 of controlling second coil switch on, second kind of scheme of outage sees also Fig. 2 (a), and face shield 16 also comprises photo-detector 28.Photo-detector 28 comprises:
Photodiode 281, photodiode 281 have positive and negative two electrodes, the only just conducting when photodiode 281 is subjected to illumination of these two electrodes;
An electrode of photodiode 281 connects an end 112 of power supply, and another electrode connects the control utmost point of controllable silicon 283 by resistance 282;
The positive pole of controllable silicon 283 (or negative pole) connect to connect an end 112 of power supply, with an electrode that is connected photodiode 281 be the same end 112 of same power supply, an end of negative pole (or anodal) connection second coil 272;
The other end of second coil 272 connects the other end 111 of power supply;
See also Fig. 2 (b), the power supply among Fig. 2 (a) can be the out-put supply 111,112 of electric welding machine 11.Power supply among Fig. 2 (a) also can be 220V or 380V power supply 10 (not shown), and so intelligent electric welder's helmet is just separate with the arc welding operation.
In the system shown in Fig. 2 (b), when producing electric arc between welding rod 13 and the workpiece 15, two electrode conductions of photodiode 281, the control utmost point along resistance 282 output currents to controllable silicon 283.The positive pole of controllable silicon 283, negative pole conducting, thus the two ends 273,274 of second coil are all switched on.
In the system shown in Fig. 2 (b), when the arc welding operation stopped, electric arc disappeared.Two electrodes of photodiode 281 disconnect, no longer to the control utmost point output current of controllable silicon 283.Positive pole, the negative pole of controllable silicon 283 also disconnect, thereby make two ends 273,274 outages of second coil.
Therefore, the intelligent electric welder's helmet shown in complex chart 2 (a), Fig. 2 (b), when the arc welding operation begins, two ends 273,274 energisings of second coil, optical filter 21 rotates and hides the perspective window 161 ' of face shield 16 '.When the arc welding operation stops, two ends 273,274 outages of second coil, optical filter 21 rotates and leaves the perspective window 161 ' of face shield 16 '.
See also Fig. 3, in the embodiment of two intelligent electric welder's helmets shown in Fig. 1 (a), Fig. 2 (a), rotating shaft 22 and disk 23 all can be replaced by a rotary crankshaft 22 '.Rotary crankshaft 22 ' is Z-shaped, and rotary crankshaft 22 ' is fixed in face shield 1 rotationally and draws, near and a limit of the perspective window 161 ' of parallel face shield 16 '; Second fixture 232 is fixed in the outer end of rotary crankshaft 22 '.At this moment, rotating shaft 22 is equivalent to a limit being fixed in face shield 16 ' of rotary crankshaft 22 ', the radius of disk 23 is equivalent to limit, centre of rotary crankshaft 22 ', and the thickness of disk 23 is equivalent to another limit that is used for fixing second fixture 232 of rotary crankshaft 22 '.
In sum, this utility model intelligence electric welder's helmet can be followed the arc welding operation and be rotated optical filter automatically, thereby protection operator's eyes and skin of face are that one of existing electric welder's helmet is improved greatly in fact.
