By adopting the device, automatic detection of prevention of wrong welding and reverse welding of the nut and wrong welding of the bolt can be realized, the product percent of pass can be improved, labor intensity and pressure of a worker can be relieved, and waste of manual work and material resources are avoided.
Description
Technical field
The utility model relates to the automobile industry welding equipment, and feature is when welded nut, can prevent that nut from putting back and misplacing, and during weld bolt, can prevent that bolt from misplacing.
Background technology
Nut-welding, usually one side has salient point, during welding, nut has the one side of salient point to fit with plate, if during placing nut, nut there is the one side of salient point to deviate from plate, can not realize welding effect, so in this case, in the situation that namely nut is placed anti-, welding equipment should stop welding.In addition, nut has all size, if misplaced nut when welding, welding equipment can not weld, otherwise welding work pieces can be scrapped.Same bolt also has all size, and the same bolt also has longly to be had shortly, if misplaced bolt during welding, welding equipment can not weld equally.Traditional method is to adopt to guarantee that manually nut does not put back, and nut does not misplace and bolt does not misplace.This mode poor reliability, operative employee's labour intensity is large, pressure is large, if nut has put back, perhaps nut has misplaced, bolt has misplaced, and the operative employee does not in time find, welding equipment can continue to implement welding, and the product that welds out like this will be scrapped or need to reprocess, waste of manpower, material resources.
Summary of the invention
When the purpose of this utility model is to solve nut-welding, prevent from that nut from putting back to misplace, realize that nut puts back the automatic detection that misplaces, and during bolt welding, prevent that bolt from misplacing, realize the automatic detection that bolt misplaces.Improve product percent of pass, reduce operative employee's labour intensity and pressure.Avoid manually reaching the waste of material resources.
Nut counnter attack error prevention device, comprise mechanical part and Programmable Logic Controller or be called the PLC control system, mechanical part comprises: bottom electrode holding rod, without oily lining, spring, test rod, reflecting component, insulator cap, nut bottom electrode, non-contact displacement transducer and sensor mount, the bottom electrode holding rod is for connecting main body, pack into successively in bottom electrode holding rod upper end spring, test rod, insulator cap, nut alignment pin, nut bottom electrode; The guide holder of packing into successively in bottom electrode holding rod lower end is without oily lining, reflecting component, displacement transducer installing rack and non-contact displacement transducer.During work, first plate is inserted in the nut alignment pin, then nut is inserted in the nut alignment pin.
The bolt error prevention device, its structure and nut are basic identical, just do corresponding design according to the features of shape of bolt, comprise mechanical part and Programmable Logic Controller or be called the PLC control system, mechanical part comprises: bottom electrode holding rod, without oily lining, spring, test rod, reflecting component, insulator cap, bolt bottom electrode, non-contact displacement transducer and sensor mount, the bottom electrode holding rod is for connecting main body, pack into successively in bottom electrode holding rod upper end spring, test rod, insulator cap, Bolt to position cover, the bolt bottom electrode; Pack into successively in bottom electrode holding rod lower end guide holder, without oily lining, reflecting component, displacement transducer installing rack and non-contact displacement transducer.During work, first plate is inserted in the Bolt to position cover, then bolt is inserted in the Bolt to position cover.
Working method:
1, the nut counnter attack arranges: before the welding beginning, the workpiece of needs welding is placed on bottom electrode, then nut just is being placed on workpiece, the nut counnter attack in touch-screen is being arranged button put ON, allowing top electrode push down nut and workpiece, with the value of displacement transducer of this moment as zero-bit, and the bound tolerance is set in touch-screen, to adapt to the difference in height of different nut salient points, be placed on workpiece nut is counter at last, button is set puts OFF, can complete nut counnter attack setting this moment.During welding, if nut is just put, the displacement that reflecting component descends to be detected be that ON arranges scope to displacement transducer, welding equipment can weld, put if nut is counter, the displacement that reflecting component descends to be detected be that OFF arranges scope to displacement transducer, and welding equipment can not weld.A detects distance, is respectively A1 and A2 under two states.
2, the nut mistake proofing arranges: before the welding beginning, the workpiece of needs welding is placed on bottom electrode, the nut that then will need to weld just is being placed on workpiece, the nut mistake proofing in touch-screen is arranged button put ON, allows top electrode push down nut and workpiece, with the value of displacement transducer of this moment as zero-bit, and the bound tolerance is set in touch-screen, to adapt to the difference in height of different nut salient points, at last other nut is placed on workpiece, button is set puts OFF, can complete nut mistake proofing setting this moment.During welding, if correct nut is just put, the displacement that reflecting component descends to be detected be that ON arranges scope to displacement transducer, welding equipment can weld, if nut has misplaced, the displacement that reflecting component descends to be detected be that OFF arranges scope to displacement transducer, and welding equipment can not weld.A detects distance, is respectively A1 and A2 under two states.
3, the bolt mistake proofing arranges: before the welding beginning, the workpiece of needs welding is placed on bottom electrode, the bolt that then will need to weld is placed in bottom electrode, the bolt mistake proofing in touch-screen is arranged button put ON, allows top electrode push down bolt and workpiece, with the value of displacement transducer of this moment as zero-bit, and the bound tolerance is set in touch-screen, to adapt to the difference in height of different bolt salient points, at last other bolt is placed on workpiece, button is set puts OFF, can complete bolt mistake proofing setting this moment.During welding, if put into correct bolt, the displacement that reflecting component descends to be detected be that ON arranges scope to displacement transducer, welding equipment can weld, if misplaced bolt, the displacement that reflecting component descends to be detected be that OFF arranges scope to displacement transducer, and welding equipment can not weld.A detects distance, is respectively A1 and A2 under two states.
Can find out from operation principle of the present utility model, this device is mainly when detecting by displacement transducer that nut is positive and negative to be put and different size nut when placing, depress the height difference of the reflecting component on test rod when different length bolts are placed and come the automatic decision nut whether to put back, whether misplaced and whether bolt has misplaced.This device reliability is high, and is automation detection and control, has improved product percent of pass.
