Accompanying drawing explanation
Fig. 1 is that the middle thin-walled after embodiment has welded straightens footpath Al-alloy casing.
Fig. 2 is welding tooling structural representation in embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, housing in the present embodiment comprises the first sleeve 2a and the second sleeve 3a being welded to each other successively, the first sleeve 2a internal diameter is greater than the second sleeve 3a internal diameter, and the outer end of the first sleeve 2a is welded with large flange 1a, and the outer end of the second sleeve 3a is welded with little flange 4a.
As shown in Figure 2, the welding tooling in the present embodiment comprises mandrel 1, the first positioning seat 2, the second positioning seat 7, pull bar 4, holds supporting seat 3, middle-end supporting seat 5 and withstanding tight block 8 greatly.
The first positioning seat 2 is located on mandrel and can be rotated around mandrel 1, and for locating large flange 1a, the second positioning seat 7 and the first positioning seat 2 intervals arrange, for locating little flange 4a; Pull bar 4 is laterally located between the first positioning seat 2 and the second positioning seat 7 and by the first positioning seat 2 and the second positioning seat 7 and is connected as a single entity.
Large end supporting seat 3 can be located on pull bar 4 movably, and outer end has the first cushion block 31 of being close to mutually with the first sleeve 2a; Middle-end supporting seat 5 can be located on pull bar 4 movably, and outer end has the second cushion block 53 of being close to mutually with the second sleeve 3a inwall.
Withstanding tight block 8 can be positioned little flange 4a on the second positioning seat 7, under the driving mechanism effect of (in figure, nothing shows), relative to the second positioning seat 7, can move.
