The utility model content
The utility model does not have counting control function for solving existing welding welding resistance equipment, it is untimely to cause operating personnel to revise electrode unavoidably sometimes in busy green work, it is solid and flow into the present situation of next procedure and a kind of duty of controlling welding resistance equipment by the way of guaranteeing welding electrode operating point counting number of providing to produce indivedual solder joint not prison weldings, alert operator is in time revised electrode, guarantees the welding resistance equipment that each solder joint is firm, guarantee the band calculating instrument of welding quality.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: the welding resistance equipment of band calculating instrument, comprise welding resistance equipment, calculating instrument, on welding resistance equipment, increase sensor is set, and the sensor setting is connected between welding resistance equipment and the calculating instrument, on calculating instrument, add output interface is set, output interface is connected to drive circuit, and drive circuit output is connected to control loop, and control loop is connected to the gauge tap loop of welding resistance machine.The input of intelligent calculating instrument delivered to the switching value signal on the welding resistance equipment by sensor, the intelligence calculating instrument collects this signal, calculating instrument single-chip microcomputer in house software is handled this signal, increase along with the welding machine welding times, the signal that sensor is sent here and the setting value of intelligent calculating instrument, when the difference operation result is zero, the control of intelligence calculating instrument outlet output control drive circuit disconnects welding machine work, operating personnel can't weld once more, alert operator is in time revised electrode, guarantees welding quality, guarantees that each solder joint is firm.
As preferably, sensor is a Hall sensor device.
As preferably, Hall sensor device is located on certain position of electrode cable of welding resistance equipment.
As preferably, drive circuit output is connected to warning device.The switch working state of the control loop control welding resistance machine timely alarm operation personnel of warning device simultaneously need be revised electrode work.
As preferably, warning device comprises alarm lamp, buzzer part.In time revise electrode with the mode alert operator that sound, light are reported to the police simultaneously, guarantee welding quality.
The beneficial effects of the utility model are: can welding times according to the rules in time control the work loop that disconnects welding resistance equipment, and timely alert operator is carried out the correction maintenance work to welding electrode, diameter and the shape of guaranteeing the welding electrode end are controlled within the prescribed limit, guarantee the diameter and the weldment fastness of weldering nuclear, guarantee the vehicle frame welding quality, guarantee product quality.Simultaneously because calculating instrument adopts is intelligent calculating instrument, the actual count value of intelligent calculating instrument is stored among the RAM of single-chip microcomputer, keeps these data not lose by rechargeable battery, guarantees counting effectiveness.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation block diagram of the welding resistance equipment of the utility model band calculating instrument.
The specific embodiment
Among the embodiment shown in Figure 1, the welding resistance equipment of band calculating instrument, comprise welding resistance equipment, calculating instrument, go up increase at welding resistance equipment (10) sensor (30) is set, and sensor (30) is provided with is connected between welding resistance equipment (10) and the calculating instrument (20), on calculating instrument (20), add output interface (70) is set, output interface (70) is connected to drive circuit (80), drive circuit (80) output is connected to control loop (90), and control loop (90) is connected to the gauge tap loop of welding resistance machine (10).Sensor (30) adopts Hall sensor device, and Hall sensor device is located on certain position of electrode cable (11) of welding resistance equipment (10).Gather signal and deliver to the input of intelligent calculating instrument.Drive circuit (80) output is connected to warning device, and warning device comprises alarm lamp (101), buzzer (102) part, provides sound, light to report to the police simultaneously.
In the workpiece welding process, the transformer time utmost point produces the electric current of 4 to 6 kilo-amperes, flowing through welding cable and soldering turret acts on welding work pieces (51) and the welding work pieces (52), under the pressure effect of top electrode (41), bottom electrode (42), the part that metal material is melted forms weldering nuclear (60), produce plastic deformation, weldering nuclear (60) is firmly non-dismountable after removing upper and lower electrode external force.When powerful welding transformer time electrode current flows through cable in this welding process simultaneously, around cable, produce certain magnetic field; Hall element is fixed on certain position of electrode cable (11), when welding current flows through cable, the conducting under the effect of high-intensity magnetic field of Hall element switch, and the switching value signal is delivered to the input of intelligent calculating instrument; The intelligence calculating instrument collects this signal, and the single-chip microcomputer in house software is gathered, takes a sample, quantizes to determine to do the difference computing at ALU and setting value behind the useful signal to this signal.
Along with the increase of welding machine welding times, the end area of top electrode (41), bottom electrode (42) can become greatly gradually, and every square millimeter of electric current that passes through of electrode this moment diminishes gradually; Simultaneously the count value on the calculating instrument also becomes big gradually, when the signal and the setting value of intelligent calculating instrument that Hall element is sent here, when the difference operation result is zero.Intelligence calculating instrument delivery outlet solid-state relay coil obtains electricity back normally open contact closure, and outside relay coil obtains electricity, and the normally open contact closure is connected peripheral buzzer and alarm lamp, and operating personnel can hear chimes of doom and see alarm lamp; Normally closed interlock disconnects welding machine gauge tap loop, and this moment, operating personnel can't weld once more, and in time alert operator need in time be revised electrode, guarantees welding quality.Treat that this machine operation personnel by standard correction electrode and after installing, press " resetting " key of intelligent calculating instrument, next one circulation welding is carried out in the zero clearing of actual count value.If welding times on duty does not have the setting of reaching warning value, even if come off duty the cutting-off machine general supply, the actual count value of intelligent calculating instrument still is stored among the RAM of single-chip microcomputer and keeps these data not lose by rechargeable battery.
