A tool system for tightening a retrightenable wedge system in a slot of a generator stator core is presented. The tool system includes a carriage assembly and a wedge tool assembly that is pivotally coupled to the carriage assembly. The carriage assembly includes motorized drives that axially moves the tool system along the slot and holds the tool system on the slot at an axial position. The wedge tool assembly includes a torqueing socket to tighten the retightenable wedge assembly in the slot. The torqueing socket is driven by a worm gear arrangement.

The tool system as claimed in claim 1, wherein the housing comprises a hinge assembly that is configured to pivotally couple the wedge tool assembly to the tool carriage assembly. 11. A method for tightening a retightenable wedge system in a slot of a generator stator core using a tool system, wherein the retightenable wedge system comprises a first filler layer placed on a coil in the slot, a spring member placed on the first filler layer, a second filler layer placed on the spring member, and a retightenable wedge assembly comprising a tightening member and a slot wedge placed on the second filler layer, wherein the tool system comprises a tool carriage assembly and a wedge tool assembly pivotally coupled to the tool carriage assembly, the method comprising: axially moving the tool system along the slot by the tool carriage assembly;holding the tool system on the slot at an axial position by the tool carriage assembly; andtightening the retightenable wedge assembly by the wedge tool assembly,wherein the wedge tool assembly comprises a housing and a torqueing socket arranged on the housing, andwherein the torqueing socket is configured to be inserted into the tightening member to tighten the retightenable wedge assembly. 12. The method as claimed in claim 11, wherein the wedge tool assembly comprises a plate attached to a bottom surface of the housing by a plurality of screws. 13. The method as claimed in claim 12, wherein the wedge tool assembly comprises a worm gear arrangement arranged on the plate. 14. The method as claimed in claim 13, wherein the torqueing socket is configured to be driven by the worm gear arrangement to tighten the retightenable wedge assembly. 15. The method as claimed in claim 13, wherein the wedge tool assembly comprises a motor that is configured to drive the worm gear arrangement. 16. The method as claimed in claim 12, wherein the wedge tool assembly comprises a pair of guiding skids axially attached to the plate and spaced apart from each other, wherein the guiding skids is configured to guide the tool system axially moving along the slot, and wherein a radial position of the plate is adjustable by the screws such that the guiding skids attach to a top surface of the slot wedge. 17. The method as claimed in claim 11, wherein the wedge tool assembly comprises a shaft arranged on a top surface of the housing, and wherein the shaft is connected to the torqueing socket that is configured to move the torqueing socket in a radial direction. 18. The method as claimed in claim 17, wherein the top surface of the housing has a concave shape, and wherein the shaft is embedded in the concave shaped top surface. 19. The method as claimed in claim 17, wherein the shaft is connected to the torqueing socket via a hinge through an aperture perpetrating the housing from a bottom surface to the top surface. 20. The method as claimed in claim 11, wherein the housing comprises a hinge assembly that is configured to pivotally couple the wedge tool assembly to the tool carriage assembly.
