Technical field
The invention belongs to and determine welding field from blow, relate to a kind of fixture trailing type thin plate TIG spot welding and determine welding head device from blow.
Background technology
At present when carrying out sheet workpiece spot welding and fixing, be all adopt fixed fixture, namely being positioned sheet workpiece by fixture before welding starts and clamp, then TIG welding gun butt welding point carries out spot welding.Fixture compresses at non-spot welding point place when clamping, and owing to ensureing access for welding, so the position of clamping point is limited, also can not press close to each spot welding point completely.Simultaneously because sheet workpiece itself has very strong flexibility, when overall clamping, sheet workpiece is easy to bend and arch upward, if and when TIG spot welding sheet workpiece contact with bottom workpieces closely time easily there is the weld defect such as burn-through, through welding, percent defective is improved, thus improves manufacturing cost.
Summary of the invention
The present invention need the problems referred to above solved be in above-mentioned prior art owing to easily there is the weld defect such as burn-through, through welding sheet workpiece to contact tight during with bottom workpieces, percent defective is improved, thus increase manufacturing cost, and a kind of compression quality that can improve when sheet workpiece welds is provided, reach and ensure that the stability of welding process and the fixture trailing type thin plate TIG spot welding of welding quality determine welding head device from blow.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of fixture trailing type thin plate TIG spot welding determines welding head device from blow, comprise TIG welding gun, also comprise mounting base, pressue device, hold down gag main body, servo slide table, welding gun holding device and pressure head, described mounting base is fixedly connected on transfer mechanism, pressue device is connected with under described mounting base, hold down gag main body is connected with under described pressue device, described hold down gag main body is for compressing sheet workpiece, described hold down gag main body is connected with servo slide table, described servo slide table is connected with welding gun holding device, described welding gun holding device is clamped with TIG welding gun, described hold down gag main body be provided with pressure head bottom, described pressure head is positioned at immediately below TIG welding gun.
Described transfer mechanism is shifting carrying platform or the mechanical arm of one or more dimensions.
The compression contour shape of described pressure head is suitable with the shape of the required sheet workpiece welded.
The side of described hold down gag main body is L-type.
Described pressue device is hydraulic cylinder or pneumatic cylinder.
Compared with prior art, the invention has the beneficial effects as follows:
(1) stationary fixture of simplicity of design is only needed to position thin plate and overall clamping before welding.After the location clamping of thin plate entirety completes, fixture trailing type thin plate TIG of the present invention spot welding determines welding head device from blow can arrive bond pad locations under the driving at transfer mechanism, now pressue device work, hold down gag main body is driven to move down the thin plate compressed around solder joint, fitted completely in the thin plate at current solder joint place and bottom surface, thus guarantee welding quality, rate of reducing the number of rejects and seconds.
(2) TIG welding gun is linked together by welding gun holding device and servo slide table, in welding process can there is loss in tungsten electrode, loss can by quantitative the reflecting of welding parameter, now servo slide table can regulate the position of TIG welding gun according to the technological parameter fed back during spot welding, ensure that the distance of tungsten electrode and workpiece is constant, thus ensure stability and the uniformity of spot welding.
(3) the compression contour shape of pressure head is suitable with the shape of the required sheet workpiece welded, to adapt to the welding of difform sheet workpiece.
(4) the present invention can ensure the stable of welding and uniformity, improve welding quality, reduces input cost.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figures 1 to 3, a kind of fixture trailing type thin plate TIG spot welding determines welding head device from blow, comprise TIG welding gun 6, also comprise mounting base 1, pressue device 2, hold down gag main body 3, servo slide table 4, welding gun holding device 5 and pressure head 7, described mounting base 1 is fixedly connected on transfer mechanism, described mounting base is connected with pressue device 21 time, described pressue device is connected with hold down gag main body 32 times, described hold down gag main body 3 is for compressing sheet workpiece, described hold down gag main body 3 is connected with servo slide table 4, described servo slide table 4 is connected with welding gun holding device 5, described welding gun holding device 5 is clamped with TIG welding gun 6, described hold down gag main body 3 be provided with pressure head 7 bottom, described pressure head 7 is positioned at immediately below TIG welding gun 6.
Described transfer mechanism is shifting carrying platform or the mechanical arm of one or more dimensions.
The compression contour shape of described pressure head 7 is suitable with the shape of the required sheet workpiece 9 welded.
The side of described hold down gag main body 3 is L-type.
Described pressue device 2 is hydraulic cylinder or pneumatic cylinder.
The workflow that this fixture trailing type thin plate TIG spot welding determines welding head device from blow is as follows:
When welding, first by stationary fixture, overall Primary Location and clamping being carried out to sheet workpiece 9, ensureing that sheet workpiece 9 entirety is not subjected to displacement.Fixture trailing type thin plate TIG spot welding is determined welding head device from blow and is moved to above spot welding point position in the effect of transplanting mechanism; now pressue device 2 works; hold down gag main body 3 is driven to move down; by pressure head 7, sheet workpiece 9 is tightly pressed in bottom workpieces 8; now input protection gas; the source of welding current starting the arc, starts welding.Welded rear source of welding current current interruption, stop input protection gas, pressue device 2 works, and drives in hold down gag main body 3 and moves, remove the compression of solder joint herein.Fixture trailing type thin plate TIG spot welding is determined welding head device from blow and is moved to next bond pad locations in the driving of transfer mechanism, repeats above action and welds all positions of welding that needs.
If tungsten electrode generation loss in welding process, then servo slide table 4 drives TIG welding gun 6 to lower feeding, and feeding displacement is the waste of tungsten electrode, thus eliminates the impact of tungsten electrode loss welding quality.
For difform sheet workpiece 9, the compression contour shape of pressure head 7 is suitable with the shape of the required sheet workpiece 9 welded, and adapts to the welding of difform sheet workpiece 9.
