Description
Technical field
The present invention relates to welding equipment positioning fields, in particular to a kind of argon arc welding board self-checking device control system
System.
Background technique
Argon arc welding is to use argon gas as a kind of welding technique of protective gas.Also known as argon gas protection weldering.It is exactly in electricity
Leading to upper argon gas protective gas around arc-welding prevents the oxidation of welding zone by air insulated except welding zone.
Argon arc welding technology is that based on the principle of ordinary arc welding, the protection using argon gas to metal wlding passes through
High current makes wlding be melted into liquid formation molten bath on the base material to be welded, makes to be welded metal and wlding reaches one kind of metallurgical bonding
Welding technique prevents wlding from contacting with the oxygen in air, thus anti-due to constantly serving argon gas in high-temperature fusion weld
The oxidation of wlding is stopped, therefore can be with soldering stainless steel, iron class hardware metal.
Common argon arc welding is not suitable for the welding of the irregular roundness such as round or ellipse, and weld diameter range can not
It adjusts.
Summary of the invention
The present invention is to overcome above-mentioned drawback, a kind of argon arc welding board self-checking device control system is provided, for welding
Equipment positioning, and the detection and localization for controlling various irregular welding surfaces and soldering opening distance, are suitable for round or ellipse
Welding etc. irregular disc positions and can automatically adjust welding column pitch automatically according to welding surface position.
To achieve the above object of the invention, the technical solution adopted by the present invention is that: including HMI, PLC, slide rheostat and weldering
Rifle regulating device, HMI are connect with PLC circuit, between PLC and adjusting device for welding gun be equipped with servo motor, PLC, servo motor and
Successively circuit connection forms keying line to adjusting device for welding gun；Circuit connection is formed two-by-two by PLC, slide rheostat and power supply three
Acquisition circuit；Slide rheostat and adjusting device for welding gun are mechanically connected；
Further, slide rheostat, which is also mechanically connected, roller bearing, and roller bearing rolls on Product jointing face, real
When acquire the information of welding surface, and welding surface diameter and shape information are passed into slide rheostat；
Further, the working principle of argon arc welding board self-checking device control system comprising the steps of:
S1: slide rheostat is equipped with red route and green route at its both ends, and middle slip end is equipped with blue route, electricity
Source anode and red connection, cathode and green connection, blue connection to PLC analog input rectify pole, PLC
Analog input end cathode is connect with the power cathode.
S2: the power supply is 5V DC power supply, and PLC acquires 0~5V voltage signal, selects resolution ratio corresponding for 4000,0V
0,5V corresponding 4000, and when being positioned, HMI can show current position value (current value).
According to the existential value interval of voltage signal in S3:PLC, minimum value is current value -10, and maximum value is current
Value+10, in motion process, the rolling bearing is moved along welding surface so that slide rheostat according to welding surface shape not
Rule is stretched, then the size that PLC acquires numerical value changes.
S4: when slide rheostat compresses, welding surface diameter becomes larger, then welding gun needs to retreat, and the numerical value of PLC acquisition at this time is big
In greatest measure, therefore PLC exports the pulse retreated to servo motor, after Serve Motor Control adjusting device for welding gun controls welding gun
It moves back, until the numerical value of PLC acquisition is in value interval, PLC stops output pulse.
S5: similarly, when slide rheostat extends, welding surface diameter becomes smaller, then welding gun needs to advance, PLC acquisition at this time
Numerical value is less than minimum value, therefore PLC export the pulse of advance to servo motor, adjusting device for welding gun control described in Serve Motor Control
Welding gun processed advances, until the numerical value of PLC acquisition is in value interval, PLC stops output pulse.
Due to the above technical solutions, the present invention has the following advantages over the prior art: the present invention is using rolling
Bearing directly determines product itself welding surface shape, and sliding, converts number for physical signal before and after subsequent slide rheostat
Signal, and through PLC collection analysis, the position of the welding gun of processing control in real time realizes the Intelligent welding of argon arc welding, overcomes traditional argon
Arc-welding cannot change the problem of welding automatically according to product outer diameter, increase adaptation function, improve work efficiency.
Detailed description of the invention
Fig. 1 is system schematic of the invention；
Fig. 2 is slide rheostat wiring schematic diagram of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments:
Embodiment:
A kind of argon arc welding board self-checking device control system, as shown in Figure 1, HMI is connect with PLC circuit, and PLC is electric
Road connects servo motor, servo motor connection adjusting device for welding gun forms keying line, and PLC, slide rheostat and power supply are two-by-two
Circuit connection forms acquisition route.
Above, slide rheostat, which is also mechanically connected, roller bearing, and roller bearing rolls on Product jointing face, in real time
The information of welding surface is acquired, and welding surface diameter and shape information are passed into slide rheostat.
And in this control system, keying line is regulated and controled according to the location information that is collected into of acquisition route, specifically by
PLC progress data processing, and the location information digital visual that HMI directly acquires PLC, and HMI provides manual control
Function, so that different control programs can be arranged according to different products in the automatic control of PLC, so that this control system
Applicability is stronger.
The working principle of this control system is as follows:
As shown in Fig. 2, slide rheostat is equipped with red route and green route at its both ends, middle slip end is equipped with blue
Route.
To realize acquisition of the PLC to slide rheostat signal, thus realize the acquisition of PLC Butt welding gun location information, it will be electric
