Abstract
The utility model relates to a turning device applied to a nuclear power plant excitation loop. The turning device is mounted on an excitation machine during usage, the turning device comprises a tool rest and a base, the tool rest is mounted on the base through a moving component, the moving component comprises a guide way, a moving block and a handle, the moving block is mounted on the guide way, the handle is disposed on the moving block, the tool rest is fixed on the moving block, the handle is rotated to drive the moving block to slide on the guide way, and thereby, the tool rest is driven to move. Compared with turning devices in the prior art, the turning device has the advantages that the repair time of the excitation loop is greatly shortened, and the like.
Description
Technical field
The utility model relates to a kind of cutting tool, especially relates to a kind of truning fixture for nuclear power plant's excitation ring.
Background technology
Exciter is the visual plant of Generator Set, and its reliability directly has influence on the safe operation of unit and even whole system.Exciter general with steam turbine and generator coaxle, when steam turbine rotation, drive exciter rotates together, the alternating current that send exciter inside becomes direct current through the rectifier of end, sends into the rotor of generator in order to produce magnetic field by brush and slip ring.In actual power is produced, slip ring loses circle, rough surface phenomenon because the reasons such as erosion and wear often there will be after operation a period of time, aggravates the wearing and tearing of brush, affects safety and the long-term operation of unit.The method of taking is at present to change slip ring and brush, and required repair time is longer.
Utility model content
The purpose of this utility model is exactly to provide a kind of truning fixture for nuclear power plant's excitation ring in order to overcome the defect that above-mentioned prior art exists, thereby has greatly shortened the repair time of excitation ring.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of truning fixture for nuclear power plant's excitation ring, this instrument is arranged on exciter while use, it is characterized in that, described instrument comprises knife rest and base, described knife rest is arranged on base by moving assembly, described moving assembly comprises guide rail, movable block and handle, described movable block is arranged on guide rail, described handle is arranged on movable block, described knife rest is fixed on movable block, drive movable block to slide on guide rail by turning handle, thereby be further with movable knife rack to move.
Described floor installation is on exciter.
On described knife rest, cutter head is installed.
Described knife rest is I-shape construction, and described cutter head is embedded in the groove of I shape knife rest one end.
Described knife rest is provided with fastening bolt, and this fastening bolt is fastenedly connected with cutter head through after knife rest upper surface.
Described knife rest is the knife rest of c6140 lathe.
Compared with prior art, the utlity model has following advantage:
Easy to operate, thus repair time of excitation ring greatly shortened, only need with about eight hours.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein 1 is knife rest, and 2 is moving assembly, and 3 is base.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite taking technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
As shown in Figure 1, a kind of truning fixture for nuclear power plant's excitation ring, this instrument is arranged on exciter while use, and described instrument comprises knife rest 1 and base 3, and described base 3 is arranged on exciter.Described knife rest 1 is arranged on base 3 by moving assembly 2.Described moving assembly 2 comprises guide rail, movable block and handle, described movable block is arranged on guide rail, and described handle is arranged on movable block, and described knife rest is fixed on movable block, drive movable block to slide on guide rail by turning handle, thereby be further with movable knife rack to move.
On described knife rest, cutter head is installed.Described knife rest is I-shape construction, and described cutter head is embedded in the groove of I shape knife rest one end.Described knife rest is provided with fastening bolt, and this fastening bolt is fastenedly connected with cutter head through after knife rest upper surface.Described knife rest is the knife rest of c6140 lathe.
The utility model uses the knife rest of c6140 lathe by being loaded on the base of making according to on-site actual situations, and base and exciter are fixed cutter head after fixing on knife rest, adjusts just can carry out slip ring and repaired.
Repair process: (1) surveys the degree of eccentricity of generator negative excitation slip ring with magnetic power meter, check rotor ring radial beat eccentricity, determines turning amount; (2) the adjustment height of cutter head and the center of rotor are contour, adjust cutter head moving axially and axis keeping parallelism along rotor; (3) start Turbine Barring Gears; (4) depth of cut of manipulation cutter head, a general depth of cut exists
left and right, is started to steam turbine extreme direction by generator end, slowly vertically turning generator excitation slip ring in alignment to end; (5), by end in alignment returning vertically, repeat previous step; (6) through repeatedly repeating until smoothing excitation slip ring; (7) use sand papering excitation slip ring to surface roughness Ra 1.6--Ra0.8.
Claims (6)
1. the truning fixture for nuclear power plant's excitation ring, this instrument is arranged on exciter while use, it is characterized in that, described instrument comprises knife rest and base, described knife rest is arranged on base by moving assembly, described moving assembly comprises guide rail, movable block and handle, described movable block is arranged on guide rail, described handle is arranged on movable block, described knife rest is fixed on movable block, drive movable block to slide on guide rail by turning handle, thereby be further with movable knife rack to move.
