Abstract
The utility model discloses a kind of anti-bias welder of nut projection welding, including bottom electrode, the alignment pin of installation on the bottom electrode, also include blowning installation, the blowning installation includes the breather pipe of blow gun, external gas source, connection blow gun and external gas source, the blow gun is arranged on the side of bottom electrode, and blow gun position is slightly above bottom electrode upper end face.Using anti-bias welder of the present utility model, the nut that easily can be deflected away from position by blowning installation is blown out outside electrode scope, so as to avoid situation about being partially welded.The utility model is simple in construction, and cost is low, and it is not high to design implementation requirement, it is to avoid evade analogue using very complicated detection means.
Description
Technical field
The utility model is related to the anti-bias welder of a kind of nut projection welding for welding automobile body.
Background technology
Automobile industry nut projection welding is a kind of very common welding sequence, and the nut quantity of projection welding is as little as several, at most several
Ten, or even have the situation of hundreds of, due to the need of manually-operated dangerous and uncertainty, and work quality and efficiency
Ask, major part company is substantially by the way of automatic welding at present.
The automatic technology for sending nut and the correlation technique of welding comparative maturity, in the market application it is also very wide
It is general.But nut conveyor is during nut is conveyed, conveying situation not in place occurs for the probability for having very little, and now pole holds
Easily occurs the situation that nut is partially welded.Although such case odds once occurs than relatively low, production line will be influenceed
Normal operation.
Avoid the situation of solder skip using two ways substantially in the market, one is detection, and whether is detection welding post
There is nut.When there is nut with without nut on station, the stroke of Top electrode is different.When having nut, the movement of Top electrode
It is long when distance is than without nut, so by the setting of detection switch position, can easily determine whether there is nut, enter
And judge whether to need to alarm to point out operator, so as to avoid the situation of solder skip；Two be to count, and one is counted by counter
Total welding of individual circulation completes number, if this numerical value be less than it is contemplated that if alarm operator, have unwelded completion in this process
Part, it is necessary to extract.Both modes have a drawback, if nut is now just within the scope of electrode,
It can not detect, ultimately result in and there is defective work.
The content of the invention
The utility model is welded there is provided a kind of nut projection welding is anti-bias for technical problem present in above-mentioned prior art
Put, when the position that nut is conveyed is deflected away from, it is to avoid situation about being partially welded.
The technical solution adopted in the utility model is as follows：A kind of anti-bias welder of nut projection welding, including bottom electrode, be arranged on
Alignment pin on bottom electrode, in addition to blowning installation, the blowning installation include blow gun, external gas source, connect blow gun and external
The breather pipe of source of the gas, the blow gun is arranged on the side of bottom electrode, and blow gun position is slightly above bottom electrode upper end face.
Preferably, the blowning installation includes two blow guns, and two blow guns are connected by breather pipe with external gas source respectively,
Two blow gun scattering devices are in the side of bottom electrode.
Further, in addition to PLC control system, magnetic valve, magnetic valve and PLC control system electricity are provided with breather pipe
Gas is connected, and PLC control system controls the valve switching times of magnetic valve.
When nut convey position deflect away from, but can complete welding when, nut normally bear against alignment pin nearby or stop
Stay near alignment pin, but do not deflect away from outside the scope of Top electrode.Now, using anti-bias welder of the present utility model, pass through
The nut that blowning installation easily can deflect away from position is blown out outside electrode scope, so as to avoid situation about being partially welded.
The utility model is simple in construction, and cost is low, and it is not high to design implementation requirement, it is to avoid advised using very complicated detection means
Keep away analogue.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the anti-bias welder of a kind of nut projection welding of the present utility model, including bottom electrode 1, installed in bottom electrode
On alignment pin 2, in addition to blowning installation, the blowning installation includes blow gun 3, external gas source（Not shown in figure）, connection blow
The breather pipe of mouth 3 and external gas source（Not shown in figure）, the blow gun 3 is arranged on the side of bottom electrode 1, and the position of blow gun 3 is slightly higher
In the upper end face of bottom electrode 1.Blowning installation described in the present embodiment includes two blow guns 3, and two blow guns 3 pass through breather pipe respectively
It is connected with external gas source, two scattering devices of blow gun 3 are in the side of bottom electrode.Also include PLC control system in the present embodiment（Figure
Not shown in）, magnetic valve is provided with breather pipe（Not shown in figure）, magnetic valve and PLC control system be electrically connected, PLC controls
System processed controls the valve switching times of magnetic valve.
The utility model is by bottom electrode side increase blowning installation, to remove the incorrect nut of transfer position.When
When the position of nut conveying is correct, the centre bore of nut is just enclosed on alignment pin.When nut convey position deflect away from,
But when can complete welding, nut normally bears against alignment pin nearby or rested near alignment pin, but does not deflect away from Top electrode
Scope outside.Now, the time of magnetic valve its switch valve on breather pipe is controlled by PLC control system, air pressure is regulated, blows
The nut that the gas of mouth blowout easily can deflect away from position is blown out outside electrode scope, so as to avoid the feelings being partially welded
Condition.
Above example is only that preferred embodiment of the present utility model is described, not to structure of the present utility model
Think and scope is defined.On the premise of the utility model design concept is not departed from, this area ordinary person is new to this practicality
The all variations and modifications that the technical scheme of type is made, all should drop into protection domain of the present utility model.
