Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The invention provides a kind of robot welding fracture of wire detection alarm device, its operation principle is: by discharging stop and charging stop, welding wire stretches process and prevents it from occurring rocking in using; Owing to welding wire is thinner in order to facilitate sensor sensing, arranging a detection plate that can rotate upwardly and downwardly at welding wire through place, sensor just can know whether welding wire by detecting detection plate.
Below in conjunction with embodiment and detailed description of the invention, the present invention is further detailed explanation.
Embodiment
As depicted in figs. 1 and 2, a kind of robot welding fracture of wire detection alarm device, including the housing 1 being arranged on robot welding wire and putting mouthful front end, and it is respectively arranged with discharging stop 2 and charging stop 7 along described housing about 1 two ends of welding wire 3 course bearing, guide pillar one that wherein discharging stop 2 includes being embedded on housing and for fixing the securing member one of guide pillar one, guide pillar one is wherein provided with one and is intended for the through hole one that welding wire 3 passes through, the inlet port place flare of this through hole one; Guide pillar two that charging stop 7 includes being embedded on housing and for fixing the securing member two of guide pillar two, is wherein provided with one and is intended for the through hole two that welding wire 3 passes through on guide pillar two, the inlet port place flare of this through hole two. Such welding wire enters from charging stop 7, passes housing cavity, goes out from discharging stop 2, by discharging stop 2 and charging stop 7, the swing of welding wire is limited, and this device can be good at welding wire 3 is positioned.
After welding wire being positioned by said method, being provided with the detection plate 6 that can swing up and down at housing 1 inner chamber, and the leading section of detection plate 6 contacts with welding wire and rests on welding wire, when such welding wire exists, detection plate 6 is swung up; Wire tip is after detection plate 6, and detection plate 6 lacks stress can swung downward. By observing the such action of detection plate 6, being positioned at housing 1 inner chamber and be additionally provided with the sensor 4 for detecting detection front edge of board portion, such sensor 4 can detect welding wire very well and there is situation. Specific as follows:
Being positioned at housing 1 bottom and be provided with mounting seat 5, be positioned at mounting seat 5 and be provided with a breach, be positioned at this indentation, there and be provided with a roll shaft, this roll shaft is connected with one end of detection plate 6, so that detection plate 6 can carry out arcuate oscillating motion centered by roll shaft. Wherein said detection plate 6 is made up of leading section and rearward end, and in folding shape distribution between leading section and rearward end, between angle between the two 120 ° to 160 °, concrete angle will with reference to the length ratio between leading section and rearward end, and it is parallel that optimum position is that welding wire stretches between rear leading section and welding wire. Roll shaft is connected with rearward end in the present embodiment.
It is positioned at the housing at place above mounting seat 5 and is provided with fixing plate 8, be positioned on described fixing plate 8 and be provided with the cavity passed through when swinging for detection plate 6 leading section, be positioned on the fixing plate 8 above cavity and described sensor 4 is installed.
