Into each blade has two solder joints with core circle contact position, and one is located at inner ring, and one is located at outer ring；Blade 11 needs and core
The welding (as shown in Figure 1) of circle 12 needs to position the two before, but is relied primarily in conventional processes and manually position,
There is no supporting positioning tool, its locating effect is poor, influence blade and core circle welding effect.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of good positioning effect, are applicable blade, core circle weld job
The positioning tool of transformer turbine blade core circle.
In order to solve the above technical problems, the invention provides a kind of positioning tool of transformer turbine blade core circle；
Including blade seat board, blade positioning shaft sleeve, lower bolster and some alignment pins, blade seat board lower surface is provided with receiving liquid
The blade of power torque converter turbine and the groove of core circle, the electrode bar turnover that blade seat board upper surface is provided with some confession welding equipments are recessed
The electrode hole of groove, the position of electrode hole is corresponding with core circle junction welding position with blade, is provided with the cell wall of groove some
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 is provided with limitation hydraulic moment changeable
The positioning tooth of the leaf position of device turbine, blade positioning shaft sleeve outer wall bottom is provided with external screw thread, and lower bolster center is fixedly connected with
Through the nut of tightening of its upper and lower end face, lower bolster tighten nut sleeve mounted in blade positioning shaft sleeve it is outer 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 and core circle of transformer turbine are integrally attached to the change of this fluid power
In the positioning tool of square device turbo blade core circle.
Technology contents of the invention are understood in order to clearer, below by the positioning of this transformer turbine blade core circle
Frock 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 the position of core circle relatively moves when preventing spot welding operation.
Brief description of the drawings
Fig. 1 is a weld through turbo blade, the core circle schematic diagram for completing.
Fig. 2 is the structural representation of this spot welding device embodiment tool locating component.
Fig. 3 is the decomposing schematic representation of this spot welding device embodiment tool locating component.
