Detailed description of the invention
As Figure 1-3, the technical solution of the utility model is: a kind of girth welding jig, comprises clamping device and positioner,
Described clamping device, comprise vertical plate 1 and be evenly located at the connecting rod 2 on vertical plate 1, and described vertical plate 1 is connected with guide 3 left end, described connecting rod 2 is hinged with clamping hook 4 one end, be hinged with the location-plate 5 being located at guide 3 right part in the middle part of described clamping hook 4, and described location-plate 5 can slide on guide 3, spring is provided with between described vertical plate 1 and location-plate 5, and to be describedly vertically connected with rotating mechanism on the left of anti-1, drive clamping device uniform rotation, described rotating mechanism comprises casing 6, motor is provided with in described casing 6, be connected with casing 6 on the left of described vertical plate 1, and its center is provided with through hole, electric machine main shaft 7 is through through hole, and be provided with axle sleeve 8 between vertical plate 1 and electric machine main shaft 7, the side that location-plate 5 is connected with guide 3 is provided with groove, one end that described axle sleeve 8 is provided with convex edge is placed in described groove, and be bolted between the convex edge of axle sleeve 8 and location-plate 5, location-plate 5 right flank center line is provided with holding tank,
Positioner is provided with on the right side of clamping device, described positioner comprises location driven shaft 9, and described location driven shaft 9 and holding tank concentric, and positioner is connected with travel mechanism, band dynamic positioning system moves left and right, and described travel mechanism comprises cylinder, described cylinder piston rod is connected with bearing, described holder top is provided with location driven shaft, and bearing bottom is connected with guide rail, and described cylinder is fixed on guide rail.
In the present embodiment, described guide 3 outer surface is provided with guide groove, described vertical plate 1 is provided with the guide rail adapted with guide groove, and between vertical plate 1 and location-plate 5, be provided with the spring be arranged in guide groove, described connecting rod 2 and clamping hook 4 form clamp arm, and described vertical plate 1 is evenly provided with 3 groups of clamp arms, driven shaft 9 front end, described location is wedge shape, described location driven shaft 9 is connected with bearing by bearing, and described bearing is provided with adjustable welding gun.
