Abstract
The invention discloses a device for preventing inverted welding of a nut in the automobile industry, relates to welding equipment in the automobile industry, in particular to a device capable of preventing inverted placing of the nut which is being welded. The device comprises a precise reducing valve, a speed control valve, a digital pressure switch, a fait6 air tube, a quick insert tube joint, a nut top electrode, a top electrode holder, a nut bottom electrode and a PLC (programmable logic control) system. By the aid of the device for preventing inverted welding of the nut in the automobile industry, automatic detection for inversion prevention of the nut can be realized, product percent of pass is increased, labor intensity and pressure of operators are reduced, and waste of manual work and material resources is avoided.
Description
Technical field
The present invention relates to the automobile industry welding equipment, especially when welded nut, can prevent the anti-reverse device that nut is placed anti-.
Background technology
Nut-welding, usually one side has salient point, nut has the one side of salient point to fit with plate during welding, if have the one side of salient point to deviate from plate on nut during placing nut, then can not realize welding effect, so in this case, in the situation that namely nut is placed anti-, welding equipment should stop welding.Traditional method is to adopt to guarantee that manually nut do not put back.This mode poor reliability, operative employee's labour intensity is large, and pressure is large, and if nut has been put back, the operative employee does not find in time that again then 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 object of the invention is to solve nut-welding, prevent that nut from putting back, realize the automatic detection that nut is put back.Improve product percent of pass, reduce operative employee's labour intensity and pressure.Avoid manually reaching the waste of material resources.
Technical scheme of the present invention is automobile industry nut-welding anti-reverse device: comprise precise pressure-reducing valve, speed control valve, digital pressure switch, tracheae and fast spigot joint, nut top electrode and top electrode holding rod, nut bottom electrode and PLC control system (Programmable Logic Controller).Connect precise pressure-reducing valve, speed control valve, digital pressure switch and top electrode holding rod by tracheae with the spigot joint of being connected, top electrode holding rod, top electrode, nut alignment pin, bottom electrode and lower electrode holder are sequentially installed.
First plate is inserted in the nut alignment pin during work, will be with again the salient point nut to be inserted in the nut alignment pin.
The concrete structure of this device and assembling mode are: this device is take tracheae and pipe joint as connecting main body, above electrode holder, and top electrode, bottom electrode, nut alignment pin and lower electrode holder are realization body, take PLC as control subject.Between total air inlet and top electrode holding rod, load onto successively precise pressure-reducing valve, speed control valve, tee pipe coupling and digital pressure switch.
Working method: at first set a force value by precise pressure-reducing valve, this force value shows by digital pressure switch, when just putting nut, nut is fitted without salient point surface and the pole-face that powers on, and nut bore and nut alignment pin are fitted, and the gas that enters in the top electrode holding rod can't be discharged, air pressure will soon reach the set force value of precise pressure-reducing valve, PLC detects the force value that force value that digital pressure switch shows meets setting, provides a control signal, and welding equipment can weld.If nut has been put back, nut has salient point surface and powers on just can not fit between the pole-face, the gas that enters in the top electrode holding rod will be discharged the gap between nut and top electrode, air pressure does not just reach the force value that precise pressure-reducing valve sets yet, PLC detects the force value that force value that digital pressure switch shows does not meet setting, provide a control signal, welding equipment can not weld.
Can find out that from operation principle of the present invention owing to adopted precise pressure-reducing valve and digital pressure switch, the upper a little air pressure change that needs only of this gas circuit just can reflect at once, and be detected by the PLC control system.Thereby whether nut put back in time controlled.This nut anti-reverse device reliability is high, and is automation detection and control, has improved product percent of pass.
Description of drawings
Fig. 1 is syndeton schematic diagram of the present invention, wherein: the total air inlet of 1-, 2-precise pressure-reducing valve, the 3-speed control valve, the fast spigot joint of 4-tracheae, 5-three-way connection, the digital pressure switch of 6-, 7-tracheae, 8-top electrode holding rod, the 9-top electrode reaches, 10-band salient point nut, 11-plate, 12-nut alignment pin, the 13-bottom electrode, the 14-lower electrode holder.
The specific embodiment
As shown in Figure 1, the present invention mainly comprises precise pressure-reducing valve 2, speed control valve 3, digital pressure switch 6, ￠ 6 tracheaes 7 and fast spigot joint 4 or three-way connection 5, nut top electrode 9 and top electrode holding rod 8, nut bottom electrode 13 and PLC control system.
The concrete structure of this device and assembling mode are: this device is take tracheae 7 and pipe joint 4 as connecting main body, above electrode holder 8, and top electrode 9, bottom electrode 13, nut alignment pin 12 and lower electrode holder 14 are realization body, take PLC as control subject.Between total air inlet 1 and top electrode holding rod 8, load onto successively precise pressure-reducing valve 2, speed control valve 3, tee pipe coupling 5 and digital pressure switch 6.First plate 11 is inserted in the nut alignment pin 12 during work, will be with again salient point nut 10 to be inserted in the nut alignment pin 12.
