The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, welding gun anticollision device, collision-prevention device 1 of the present invention is connected with welding gun 2 excircles, specifically is connected with the excircle at the rear portion of welding gun 2 main bodys.
To shown in Figure 5, welding gun anticollision device, collision-prevention device 1 of the present invention comprises: connecting rod 11, switch base 13, switch 14 and spring 12 as Fig. 2.The support 3(that one end of connecting rod 11 connects on the welding robot please refer to Fig. 1), the other end is pushed down by spring 12, and switch 14 is installed on the switch base 13.Under the normal condition, connecting rod 11 is pushed down switch base 13 under the pressure of spring 12, also namely pushes down the switch 14 that is installed on the switch base 13, makes switch 14 be in closure state, the welding robot operate as normal.So-called " closure state " refers to that switch is in the state of ON.When the tip of welding gun is subjected to stopping, connecting rod 11 skews, cut-off switch 14 makes switch 14 send cut-off signal to welding robot by holding wire, and welding robot is quit work.So-called " cut-off switch " refers to that switch changes the state of OFF over to.
Particularly, as shown in Figure 4, switch base 13 is provided with 3 switch bit 131 and 14 series connection of 132,3 switches of 1 through hole, and is installed in 3 switch bit 131 respectively.The end that connecting rod 11 connects support 3 passes through hole 132, and connecting rod 11 is provided with annular projection 111, and the front end 111a of circular protrusion 111 blocks switch base 13, also namely pushes down 3 switches 14, and the rear end 111b of circular protrusion 111 blocks spring 12, is also namely pushed down by spring 12.Those skilled in the art can understand, the quantity of switch 14 is not limited to 3, switch 14 series connection of 2,4 or other quantity can be set, the present invention adopts the benefit of 3 switches, 14 series connection to be: when the tip of welding gun is subjected to stopping, connecting rod 11 skews, as long as disconnection wherein any one switch 14 can realize that switch 14 sends cut-off signal to welding robot by holding wire, described welding robot is quit work, increased crashproof sensitiveness.The inventor finds in experimentation, and the situation of 1 or 2 switch 14 series connection only is set, and in the time of usually can not being subjected to stopping at the tip of welding gun, disconnects sensitively, influence crashproof effect, and the effect of 3 switch 14 series connection is very superior.
Among the present invention, switch 14 preferred fork type switches, as shown in Figure 5, fork type switch comprises fork 141 and button 142, fork type switch specifically can be selected from Omron Corp.Under the normal condition, connecting rod 11 is pushed down fork 141, pushes down button 142 by fork 141, makes fork type switch be in closure state, the welding robot operate as normal.When the tip of welding gun 2 was subjected to stopping, connecting rod 11 skews discharged fork 141, thereby release-push 142 makes fork type switch send cut-off signal to welding robot by holding wire, and welding robot is quit work.
By such scheme as can be seen; when the tip of welding gun is subjected to stopping; above-mentioned welding gun anticollision device, collision-prevention device in time quits work welding robot; and data reset; in order to avoid welding gun and workpiece etc. cause heavy losses; can effectively protect equipment such as welding gun and workpiece, also can not depart from the target setting position because of collision.
As shown in Figures 2 and 3, as preferred version,, the welding gun anticollision device, collision-prevention device is provided with shell 15, top cover 16 and bottom 17, and top cover 16 and bottom 17 are installed in the front-end and back-end of shell 15 respectively.Spring 12, switch base 13 and switch 14 are arranged in the cavity of described shell 15, top cover 16 and bottom 17 formation, and the front end of connecting rod 11 (end that namely connects support 3) passes from top cover 16.
As shown in Figure 1, shell 15 is provided with installation position 151, welding gun anticollision device, collision-prevention device 1 is installed in the excircle of welding gun 2 by installation position 151.Particularly, can welding gun anticollision device, collision-prevention device 1 be installed in the excircle of welding gun 2 by modes such as screws.
The welding gun of band anticollision device, collision-prevention device of the present invention comprises that the side in the such scheme goes out the welding gun anticollision device, collision-prevention device of formula, and the annexation of welding gun anticollision device, collision-prevention device 1 and welding gun 2 as shown in Figure 1.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described 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 specific embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
