Brief description of the drawings
Fig. 1 is structural front view of the invention,
Fig. 2 is structure right view of the invention.
Specific embodiment
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 carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1~2 are referred to, in the embodiment of the present invention, a kind of nut counnter attack mistake proofing and bolt welding error prevention device, including peace
It is dress seat 1, insulation board 2, electrode 3, sensor block 4, displacement transducer 5, retainer ring 6, cylinder 7, air cylinder supporting structure 8, guide rod 9, spacing
Groove 10, guide rail 11, briquetting 12 and fixture 13, one end upper surface of the mounting seat 1 are fixedly connected air cylinder supporting structure 8, and cylinder is solid
Determine to be fixedly connected in frame 8 cylinder body of cylinder 7, and one end of the piston rod connection guide 9 of cylinder 7, so that the regulation of distance is realized,
The other end upper surface of the mounting seat 1 is fixedly connected electrode 3, and insulation board is fixedly installed between electrode 3 and the upper surface of mounting seat 1
2, to ensure security performance, fixture 13 is fixedly mounted on the electrode 3, fixture 13 is used to fix clamping nut or bolt.
The other end of the guide rod 9 is fixedly connected briquetting 12, and the guide rod 9 is vertical with the clamping face of fixture 13, in order to press
Tight nut or bolt.
Guide rail 11 is set between the electrode 3 and air cylinder supporting structure 8, and guide rod 9 is slidably connected in guide rail 11, and guide rod 9
The limited block that surface is set is slidably arranged in the stopper slot 10 that the middle part of guide rail 11 opens up, in order to the motion of the cylinder to briquetting

Operation principle of the invention is：
Nut counnter attack：Welded nut typically simultaneously has salient point, and without salient point, during welded nut, nut has one side in addition
The one side of salient point should be fitted with plate, during due to manually putting nut, there is unstable factor, and nut may be put back is carried out
Welding（The one side that nut has salient point deviates from workpiece）, when this happens, briquetting 12 declines pushes down nut, so that gas
Cylinder piston rod, by the change of distance between sensor block and displacement transducer, feeds back to the electric-control system of equipment toward following movement,
After equipment adjustment completes to enter production status, electric-control system in advance sets the distance of reaction of displacement transducer, only exists
Can just be welded in the range of setting, beyond can not then be welded, the accuracy of detection of this displacement transducer can reach
The rank of 0.5mm, can effectively detect whether nut puts back by this detection method, there is provided the qualification rate of product, reduce
