Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, welding gun anticollision device, collision-prevention device 1 of the present invention is connected with welding gun 2 rear end, and namely the axis of the axis of welding gun anticollision device, collision-prevention device 1 main part and welding gun 2 main part rear end point-blank.
As shown in Figures 2 to 4, welding gun anticollision device, collision-prevention device 1 of the present invention comprises: in connecting rod 11, switch plectrum 13, switch 14, spring 12(Fig. 2, spring 12 is positioned at after switch plectrum 13, is blocked by switch plectrum 13, therefore not shown) and slide block 15 and socket 16.Wherein one end of connecting rod 11 is connected with welding gun 2 rear end, and the other end props up slide block 15, and one end of slide block 15 linking springs 12, switch plectrum 13 is fixed on slide block 15.Socket 16 is by holding wire (not shown) connecting welding robot (not shown).Switch 14 is by switching line 161 gang socket 16.Under normal condition, switch plectrum 13 pushes down switch 14, and make switch 14 be in closure state, welding robot normally works.So-called " closure state " refers to that switch is in the state of ON.When the tip of welding gun is subject to stopping, the connecting rod 11 be connected with welding gun rear end offsets, and Compress Spring 12, thus pull switch plectrum 13, release is cut-off switch 14 also, make switch 14 send cut-off signal, transmit described cut-off signal to welding robot by switching line 161, socket 16 and holding wire, welding robot is quit work.So-called " cut-off switch " refers to that switch proceeds to the state of OFF.It should be noted that: have many alternative can realize the same object of the present invention.Such as, above-mentioned slide block 15 can save, and switch plectrum 13 is connected directly between one end of spring 12.
In the present invention, switch 14 is Swing-Rod switch preferably, and as shown in Figure 4, Swing-Rod switch comprises fork 141, button 142 and terminal 143, and Swing-Rod switch specifically can be selected from Omron Corp.Under normal condition, switch plectrum 13 pushes down the fork 141 of Swing-Rod switch, and fork 141 pushes down button 142, and make Swing-Rod switch be in closure state, welding robot normally works.When the tip of welding gun is subject to stopping, the connecting rod 11 be connected with welding gun rear end offsets, and Compress Spring 12, thus pull switch plectrum 13, the fork 141 of release Swing-Rod switch, thus release-push 142, disconnect Swing-Rod switch, make Swing-Rod switch send cut-off signal, transmit this cut-off signal to welding robot by switching line 161, socket 16 and holding wire, welding robot is quit work.
As can be seen from the above scheme; when the tip of welding gun is subject to stopping; above-mentioned welding gun anticollision device, collision-prevention device makes welding robot quit work in time; and data reset; in order to avoid welding gun and workpiece etc. cause heavy losses; can the equipment such as available protecting welding gun and workpiece, also can not depart from setting target location because of collision.
Particularly, the switch plectrum 13 in the present invention is provided with catch 131.Under normal condition, pushed down the fork 141 of Swing-Rod switch by catch 131.Certain those skilled in the art can understand, and also have a lot of replacement scheme that switch plectrum 13 also can be made to push down the fork 141 of Swing-Rod switch.
Preferably, slide block 15 is fixed on by screw 133 in one end of switch plectrum 13, and the other end is provided with an elongate holes 132, and screw 134, through elongate holes 132, is fixed on slide block 15.The benefit done like this is: elongate holes 132 allows the other end of switch plectrum 13 to have certain activity space, when the tip of welding gun is subject to stopping, the other end of switch plectrum 13 can move with comparalive ease and leave the fork 141 of Swing-Rod switch, to discharge fork 141, trigger Swing-Rod switch and send cut-off signal to welding robot by switching line 161, socket 16 and holding wire, welding robot is quit work.
Preferably, switching line 161 is marked with PUR 17 with the junction of the terminal 143 of Swing-Rod switch, plays leakproof, fixing and insulating effect, in order to avoid disconnect with the connection of the terminal 143 of Swing-Rod switch at concussion breaker in middle line 161 repeatedly.
Preferably, welding gun anticollision device, collision-prevention device is also provided with shell 18 and upper cover 19.Switch 14, switch plectrum 13, spring 12 etc. are all located in the cavity of shell 18 and upper cover 19 formation, play the effects such as dust-proof, safe.
The welding gun of band anticollision device, collision-prevention device of the present invention, comprise the welding gun anticollision device, collision-prevention device directly going out formula in such scheme, the annexation of welding gun anticollision device, collision-prevention device and welding gun as shown in Figure 1.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
