The alignment pin of the leaf position of transformer turbine is limited, blade positioning shaft sleeve is fixedly connected on the groove center of blade seat board
Position, blade positioning shaft sleeve top penetrating blade seat board upper surface, blade positioning shaft sleeve outer wall middle part are provided with limitation hydraulic moment changeable
The positioning tooth of the leaf position of device turbine, blade positioning shaft sleeve outer wall bottom are provided with external screw thread, and lower bolster center is fixedly connected with
Nut of tightening through its upper and lower end face, lower bolster tighten nut sleeve it is outer mounted in blade positioning shaft sleeve and with blade positioning shaft sleeve
External screw thread coordinate.
After such structure, the blade of transformer turbine and the groove of core circle are placed on the groove of blade seat board
It is interior, the placed angle of the blade of transformer turbine, underlay are positioned with the positioning tooth of alignment pin and blade positioning shaft sleeve
Plate is coordinated by tightening nut with blade seat board, realizes that the blade of transformer turbine and core circle are integrally attached to the change of this fluid power
In the positioning tool of square device turbine leaf label circle.
Technology contents of the present utility model are understood in order to clearer, below by this transformer turbine blade core circle
Positioning tool is referred to as this positioning tool.
This positioning tool also includes core circle electrode, and core circle electrode is fixedly connected on the upper surface of lower bolster, core circle electrode
Upper surface is provided with the projection for agreeing with core circle outline；After such structure, the core of core circle electrode and transformer turbine
Circle coordinates, and prevents the position of core circle during spot welding operation from relatively moving.
