Description
Technical field
The utility model relates to field of electromechanical integration, is related specifically to a kind of device for lincoln electric welder fault information acquisition and diagnosis.
Background technology
Lincoln electric welder, simple to operate, sturdy and durable, the ratio of performance to price is high.Be mainly used in the welding in pipeline welding, shipbuilding industry, stainless steel welded and dual phase steel and the welding of Cr-Mo heat-resisting steel.But due to part lincoln electric welder because do not have digitadiagnosis function to cause maintenance conditions to bother very much, be more difficult to when particularly running into welding quality instability hold.So just cause maintenance work loaded down with trivial details, stop time is long, affects the problem of production efficiency.
Summary of the invention
For achieving the above object, the technical solution of the utility model is:
This device comprises lincoln electric welder, PLC, current/voltage acquisition module, wire feed rate acquisition module, waveform acquisition module, and industrial computer forms; Current/voltage acquisition module, wire feed rate acquisition module, waveform acquisition module gathers the current/voltage of lincoln electric welder, wire feed rate and waveform respectively, the signal collected is flowed to PLC, the signal collected carries out analyzing and judging and be transferred to industrial computer by PLC, industrial computer by signal filing store and by PLC judgment result displays on industrial computer.
The upper remote control software of installing of industrial computer (1) can carry out monitoring and diagnosis to equipment by internet.
Good effect of the present utility model is:
This device can record welding current voltage change curve, the wire feed rate of wire feeding motor, the waveform of output current of lincoln electric welder when producing, and go out electric welding machine real-time status and failure message according to the information diagnosis collected, display failure code and failure message, be conducive to electrical service personnel and solve fault rapidly.
Accompanying drawing explanation
Fig. 1 is the utility model structured flowchart.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing 1.
See Fig. 1, zero load, starting the arc back suction, welded condition Self-tuning System, the stable conversion of welding output, receiving the states such as arc back suction, zero load when lincoln electric welder 6 normally works, can be experienced.Each process is all controlled by special circuit part, and trouble spot may occur in arbitrary process.In the course of work, the current/voltage collected, wire feed rate and waveform are delivered in PLC2 by current/voltage acquisition module 3, wire feed rate acquisition module 4, waveform acquisition module 5.PLC diagnostic function mainly comprises following aspect:
One, the electric current of electric welding machine that collects according to current/voltage acquisition module 3 of electric welding machine output power abnormity diagnosis: PLC2 and voltmeter calculate the real output of electric welding machine, the information such as the thickness material of wire feeding motor wire feed rate and welding base metal are collected and calculated with mathematical model goes out required theoretical power according to wire feed rate acquisition module 4, can show on industrial computer 2 when theoretical power does not seriously mate with real power, now by regulating the technological parameter such as wire feed rate and the given power of electric welding machine suitably to regulate
Two, electric current, voltage, wire feed rate fault diagnosis: when the voltage normal current that current/voltage acquisition module 3 collects is too low, industrial computer 2 can be judged as electric welding machine power amplifier board fault; The wire feed rate that wire feed rate acquisition module 4 collects only have inverted speed do not have forward direction speed (can only to a direction motion) then industrial computer 2 can be judged as it being likely welding machine output cable shorted to earth; During welding, wire feed rate fluctuation is violent, then logic card fault or wire feeding motor jam, needs to check wire drive feeder mechanical part; Electric current normal voltage is too low, then arc pressing plate fault or wire feeding motor speed need to increase; Wire feeding motor speed quickly and uncontrolled, namely occurs that flying a phenomenon is then judged as wire feeding motor fault.
Three, electric welding machine output waveform diagnosis: waveform acquisition module 5 is by gathering electric welding machine output waveform, and A.C. welder is sine and cosine waveform, DC welding machine square wave or zig-zag.Now PLC2 judges according to cycle of waveform, frequency condition, and very easily magnetic blow occurs when adjacent two A.C. welder carrier phase shift 0 or 180 are spent, affect welding quality, under normal condition, phasing degree should near 90 degree.By gathering the shape information of DC welding machine, if the cycle, frequency anomaly then diagnosable go out the property abnormality of electric welding machine, need to carry out inspections reparation to corresponding power component.
Utilize this device can set up a whole set of trouble spot judging program, trouble spot is corresponded in concrete welding machine state and then for corresponding circuit module and carry out analyzing and diagnosing.All analytic process is all completed by program above, when workshop management personnel or electrical repair personnel need to monitor the working condition of electric welding machine, only need in the man-machine interface of industrial computer 1, click the corresponding button and check data and curve, if electric welding machine now breaks down, background program will be presented on interface according to the corresponding failure cause of real-time curve information analysis.Fault-signal is presented on remote monitoring screen by internet by the upper remote control software of installing of industrial computer (1), is convenient to related electric Maintenance Engineer remote diagnosis or maintenance failure.
