Detailed description of the invention
As Figure 1-3, the technical scheme is that
A kind of girth welding jig, including clamping device and positioner,
Described clamping device, including vertical plate 1 and the connecting rod 2 be uniformly located on vertical plate 1, and described vertical plate 1 with lead
Connecting to part 3 left end, described connecting rod 2 is hinged with clamping hook 4 one end, leads with being located in the middle part of described clamping hook 4
Location-plate 5 to part 3 right part is hinged, and described location-plate 5 can slide on guide 3, described vertical plate 1 with
It is provided with between location-plate 5 on the left of spring, and described vertical plate 1 and is connected with rotating mechanism, drive clamping device uniform rotation,
Described rotating mechanism includes casing 6, is provided with motor, is connected with casing 6 on the left of described vertical plate 1 in described casing 6, and
Its center is provided with through hole, and electric machine main shaft 7, through being provided with axle sleeve 8 between through hole, and vertical plate 1 and electric machine main shaft 7, positions
The side that plate 5 is connected with guide 3 is provided with groove, and one end that described axle sleeve 8 is provided with convex edge is placed in described groove, and
Being bolted between convex edge and the location-plate 5 of axle sleeve 8, location-plate 5 right flank centrage is provided with holding tank,
