Abstract
The utility model relates to a bolt hole processing tooling for inner water distribution rings of hydraulic generators, which is characterized by comprising a disk. One surface of the disk is a plane, the other surface of the disk is provided with a circular stepped boss consisting of a fixing boss and a positioning boss, the circular fixing boss and the circular positioning boss are coaxial with the disk, a positioning through hole is arranged on the fixing boss, the disk and the fixing boss penetrate through the positioning through hole, and the axis of the positioning through hole is parallel to that of the disk. When the tooling is used, the positioning boss is positioned in a guide vane hole, the fixing boss is supported on a counter bore of the guide vane hole of an inner water distribution ring, a magnetic drill is attracted onto the disk, and a drill bit of the magnetic drill penetrates through the positioning through hole provided with a guide sleeve, so that six bottom bolt holes positioned on the periphery of the guide vane hole can be processed sequentially. The positions of the bolt holes processed by the tooling are precise, the axes of the bolt holes cannot be deviated, processing efficiency is high, assembly of the inner water distribution ring cannot be affected, and repair rate is low.
Description
Technical field
The utility model belongs to hydrogenerator assembly tooling technical field, particularly relates to a kind of hydrogenerator interior admission water ring bolt hole processing tool.
Background technology
Water distributor is the crucial portion cover of hydrogenerator, and interior admission water ring is one of critical component in the water distributor.Interior admission water ring generally is welded by two flange rings and an awl tube, and the awl tube is provided with 16 stator holes that are used to install the stator lower shaft.The stator lower shaft cooperates the back to put together on the awl tube with 6 bolts with the stator hole.So, around each stator hole, generally be processed with 6 bolts hole.In the prior art, above-mentioned each bolt hole is by manually independently machining one by one, be difficult to guarantee the machining accuracy of each bolt hole under not by the condition of any spacing frock, the not corresponding phenomenon of bolt hole axis deviation and bolt hole often occurs, have a strong impact on the assembling of interior admission water ring.In addition, the working (machining) efficiency of bolt hole is low, the repair rate height.
Summary of the invention
The utility model provides a kind of simple in structure, efficiency of assembling that can improve interior admission water ring, the hydrogenerator interior admission water ring bolt hole processing tool that increases the machining accuracy of interior admission water ring upper bolt hole for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of hydrogenerator interior admission water ring bolt hole processing tool, it is characterized in that: comprise disc, the one side of described disc is the plane, the another side of described disc is provided with circular ladder boss, this ladder boss is made up of fixing lug boss and positioning boss, described circular fixing lug boss and circular positioning boss and disc coaxial line, described positioning boss is provided with the positioning through hole that runs through disc and positioning boss, and the axis of described positioning through hole is parallel with the axis of described disc.
The utility model can also adopt following technical scheme:
The quantity of described positioning through hole is 6 and along the circumferential direction is distributed on the fixing lug boss.
Be provided with chamfering between the upper surface of described positioning boss and the periphery of positioning boss.
The thickness of described disc is 10mm.The height of fixing lug boss is 25mm-35mm, and the height of positioning boss is 7mm-9mm.
In the described positioning through hole fairlead is housed.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that this frock comprises disc, the one side of described disc is provided with circular ladder boss, described ladder boss is made up of fixing lug boss and positioning boss, described fixing lug boss is provided with positioning through hole, positioning through hole runs through fixing lug boss and disc, and the axis of positioning through hole is parallel with the axis of described disc.When this frock is used, positioning boss is positioned at the stator hole, fixing lug boss is propped up on the counterbore in the stator hole of interior admission water ring, with magnetic force bore be adsorbed on the disc and with its drill bit by the positioning through hole of fairlead is housed, can process 6 bolt bottom outlets that are positioned at around the stator hole successively, accurate with the bolt hole position that this frock processes, and the phenomenon of axis deviation can not appear in bolt hole, the working (machining) efficiency height can not influence the assembling of interior admission water ring, and repair rate is low.
Be provided with chamfering between the upper surface of described positioning boss and the periphery of positioning boss.Make things convenient for the positioning boss plug-in mounting to enter in the stator hole of interior admission water ring.
