Abstract
The utility model relates to a mistake and inversion preventing device for projection-welded standard parts. The mistake and inversion preventing device is composed of a positioning pin, a lower electrode, a displacement core shaft, a spring, an electrode holder, a laser sensing part and a laser displacement sensor; the mistake and inversion preventing device is characterized in that the positioning pin is mounted in the lower electrode, the lower end of the positioning pin is connected with the displacement core shaft, the spring sleeves the displacement core shaft, the outside of the displacement core shaft sleeves the electrode holder, the laser sensing part is mounted at the bottom of the displacement core shaft, a sensor connecting support is fixed on the lower part of the electrode holder, the laser displacement sensor is fixed at the bottom of the sensor connecting support and arranged symmetrically to the laser sensing part. The mistake and inversion preventing device is capable of achieving the purposes of mistake prevention and inversion prevention by controlling the operation of the PLC (Programmable Logic Controller) of the projection welding device and a welding aid on the basis of recognizing the overall dimension and the displacement of each standard part by use of the laser displacement sensor; the mistake and inversion preventing device is accurate in recognition and reasonable in structure.
Description
Technical field
The utility model relates to a kind of projection welding standard component mistake proofing anti-reverse device, for the fail-safe system of projection welding standard component production process.
Background technology
Along with industrial mass production such as automobile industries, the standard component such as project-welding nut, screw more and more on product in advance, the specification kind of standard component is also more and more, so in production process, often occurs the phenomenon such as wrong, anti-loaded for standard component.And the projection welding mistake of standard component cannot be found often in middle operation, therefore will cause scrapping of large component even to cause scrapping of whole body of a motor car.
Summary of the invention
The purpose of this utility model is a kind of projection welding standard component mistake proofing anti-reverse device, to utilize radium-shine displacement inductor to the appearance and size of standard component and displacement is identified and then by controlling the operation of projection welding equipment PLC and welding accessory, reach the object of mistake proofing, counnter attack, its identification accurately, rational in infrastructure.
The technical solution of the utility model is achieved in that a kind of projection welding standard component mistake proofing anti-reverse device, by alignment pin, bottom electrode, displacement mandrel, spring, electrode holder, radium-shine induction pieces and radium-shine displacement inductor form, it is characterized in that: alignment pin is contained in bottom electrode, alignment pin lower end is connected with displacement mandrel, spring is equipped with in displacement core sleeve, it is outside that electrode holder is set with displacement mandrel, radium-shine induction pieces is arranged on the bottom of displacement mandrel, inductor connection bracket is fixed on the bottom of electrode holder, radium-shine displacement inductor is fixed on inductor connection bracket bottom and is arranged symmetrically with radium-shine induction pieces.
Good effect of the present utility model is the loss of having stopped in production in enormous quantities to cause that because standard component welding is wrong production line is stagnated, reprocessed, scraps etc.; Effectively guaranteed product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram while not putting nut of the present utility model.
Fig. 3 is the schematic diagram while putting back nut of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of projection welding standard component mistake proofing anti-reverse device, by alignment pin 1, bottom electrode 2, displacement mandrel 3, spring 4, electrode holder 5, radium-shine induction pieces 6 and radium-shine displacement inductor 8 form, it is characterized in that: alignment pin 1 is contained in bottom electrode 2, alignment pin 1 lower end is connected with displacement mandrel 3, displacement mandrel 3 is set with spring 4, electrode holder 5 is sleeved on displacement mandrel 3 outsides, radium-shine induction pieces 6 is arranged on the bottom of displacement mandrel 3, inductor connection bracket 7 is fixed on the bottom of electrode holder 5, radium-shine displacement inductor 8 is fixed on inductor connection bracket 7 bottoms and radium-shine induction pieces 6 is arranged symmetrically with.
The radium-shine displacement inductor 8 being connected on electrode holder 5 passes through the displacement of inductive displacement mandrel 3, and the spring 4 on its displacement mandrel 3 plays the effect that alignment pin 1 is returned to original state at work, and electrode holder 5 plays electric action with electrode at work.
During work, after the startup of projection welder starting switch, conventional PLC sends 3 instructions continuously, i.e. magnetic valve energising, power supply electric discharge, magnetic valve power-off.After magnetic valve energising, air-channel system makes welding machine cylinder move pressing part, and whether the displacement that in judgement welding accessory, the displacement of alignment pin 1 identifies the radium-shine displacement inductor 8 of displacement mandrel 3 lower ends meets the requirement of preset value, while meeting, power supply discharges and completes subsequent action, and after magnetic valve power-off, air-channel system makes welding machine cylinder move relieving part and gets back to original state.While not meeting, stopping power supply discharges and sends warning.
As shown in Figure 2,3, when equipment is elected duty as, while producing, once there is not putting nut or nut, put back phenomenon alignment pin displacement and be not inconsistent with initial setting value, equipment stops welding automatically.Reach the object of counnter attack and leakproof, simultaneously because various nut sizes all have different difference, therefore as other nuts sneaked into the displacement of rear alignment pin, certainly with initial setting value, be not inconsistent, so this equipment also can reach the object of mistake proofing.
