Fig. 1 is the three-dimensional view of preferred embodiment GIS flange butt joint positioner of the present utility model.
Fig. 2 is the front view of the GIS flange butt joint positioner among Fig. 1.
[embodiment]
For understanding the utility model better, below with reference to instantiation the utility model is described in detail.
In order to guarantee processing quality and the operating efficiency of the butt joint of GIS flange, the utility model provides a kind of GIS flange butt joint positioner.See also Fig. 1, preferred embodiment GIS flange butt joint positioner of the present utility model mainly comprises flexible jig 10, guiding Conic thread rod 20, ratchet spanner 30 three parts, and each several part accurately processes by high-strength steel.The abutted flange face of 10 pairs of GIS flanges of flexible jig carries out clamping, and the installing hole of 20 pairs of flange faces of guiding Conic thread rod positions, and ratchet spanner 30 is corrected by the installing hole alignment that nut promotes 20 pairs of flange faces of guiding Conic thread rod.Guiding Conic thread rod 20 is installed on the flexible jig 10, and its front portion is conical guide part, and the rear portion is screw rod.Ratchet spanner 30 is sleeved on the nut of guiding on the Conic thread rod 20, pulls ratchet spanner 30 and drives 20 motions of guiding Conic thread rods.
When utilizing above-mentioned GIS flange butt joint positioner to carry out the butt joint of GIS flange, the concrete operations step is as follows:
