Up to the present, friction stir welding has been proved to be except can realizing the welding of aluminum alloy materials, aluminum matrix composite, and other have light metal alloy and the nonmetallic materials also applicable application agitating friction welding technology of temperature flowing plasticity.Due to friction stir welding have without splashing, smoke dust, and not needing to add welding wire and good characteristics such as protection gas etc., is a kind of new technology of efficient, energy-saving and environmental protection.Therefore, this technology being applied to the rocket manufacturing is following development trend.In order to adapt to the application of agitating friction solder technology on rocket, realizing friction stir welding problem for carrier rocket store-vessel bottom top cover and manhole flange, proposing a kind of tank top cover and manhole flange friction stir welding welder.
Utility model content
For the defect that traditional agitating friction welding equipment exists, the utility model proposes a kind of tank top cover and manhole flange friction stir welding welder, can realize material friction stir welding welding such as aluminium alloys, solution carrier rocket store-vessel bottom top cover and manhole flange realize friction stir welding problem, break through the restriction of traditional TIG solder technology, improve the quality of connection of welding point.
In order to solve above-mentioned technical problem of the present utility model, the solution that the utility model provides is to provide a kind of tank top cover and manhole flange friction stir welding welder, primarily of mould tire, hold-down ring, compression backing plate A, compresses backing plate B, flange press ring, composition backing, repair welding backing plate, housing screw composition; Composition backing or repair welding backing plate are fixed on mould tire, are realized compressing top cover and manhole flange by hold-down ring, compression backing plate A, compression backing plate B, housing screw, flange press ring, and on five-axle linkage equipment, are realized friction stir welding welding.
Further, described hold-down ring, compression backing plate A, compression backing plate B adopt bolt, elastic washer, plain washer, nut and manhole flange to carry out fastening.
The utility model compared with prior art, its remarkable advantage:
1. compared with traditional TIG welding method, this device can realize friction stir welding welding, produces the defects such as pore, crackle or similar crackle after reducing welding, effectively improves and is welded to connect quality.
2. this device can compress product top cover and manhole flange effectively, and arranges local compaction structure;
3. this device arranges position limiting structure, effectively prevents the radial-play of top cover and manhole flange;
4. this device can realize friction stir welding and repair welding operation.

Detailed description of the invention
See the accompanying drawing that the utility model embodiment is shown, hereafter in more detail the utility model will be described.But the utility model can realize in many different forms, and should not be construed as by the restriction in the embodiment of this proposition.
A kind of tank top cover described in the utility model embodiment and manhole flange friction stir welding welder, can realize material friction stir welding welding such as aluminium alloys, by mould tire 1, bolt A2, elastic washer A3, plain washer A4, nut A5, hold-down ring 6, compress backing plate A7, compress backing plate B8, screw A9, elastic washer B10, plain washer B11, nut B12, bolt B 13, flange press ring 14, composition backing 15, screw B16, lifting bolt A17, lifting bolt B18, stop screw A19, housing screw A20, housing screw B21, stop screw B22, straight pin 23, repair welding backing plate 24 part forms.
Above-mentioned tank top cover is as follows with manhole flange friction stir welding welder operation principle: when top cover welds with manhole flange, composition backing 15 is fixed on mould tire 1, realize compressing top cover and manhole flange by hold-down ring 6, compression backing plate A7, compression backing plate B8, housing screw A20, housing screw B21, and on five-axle linkage equipment, realize friction stir welding welding; In like manner, when carrying out repair welding, repair welding backing plate 24 is fixed on mould tire 1, realizes compressing top cover and manhole flange by hold-down ring 6, compression backing plate A7, compression backing plate B8, housing screw A20, housing screw B21, and on five-axle linkage equipment, realize repair welding welding.Described hold-down ring 6, compression backing plate A7, compression backing plate B8 can adopt bolt A2, elastic washer A3, plain washer A4, nut A5 and manhole flange to carry out fastening
Because product top cover area is large, in order to ensure near the agitating friction place of being welded to connect, to there is enough thrusts with manhole flange, here adopt stop screw A19, mode that housing screw A20, housing screw B21, stop screw B22 interlock layout to realize local strengthening, its structure is as shown in Figure 2.Meanwhile, elastic washer B10, plain washer B11, nut B12, bolt B 13 pairs of product top covers can be adopted to carry out fastening.
