Abstract
The utility model discloses interior hexagonal double-ended bolt locking mechanism in a kind of nuclear power pump, including being arranged on the side wall of screw hole, locking slot, locking plate and compressor arm are set, the locking plate includes hemispherical matrix and the multiple lock ears being uniformly arranged, the centrally disposed location hole of hemispherical matrix；The lock ear is inserted into the locking slot；The end surface shape of compressor arm is consistent with the inner face shape of interior hexagonal double-ended bolt, and the end face of compressor arm sets positioning pin, the outer diameter of the positioning pin and the diameter matches of location hole；Interior hexagonal double-ended bolt is screwed in the screw hole, and the inner face of interior hexagonal double-ended bolt is abutted with locking plate.The utility model has the advantages that：Locking effect is good, and stud loose phenomenon will not occur.
Description
Technical field
The utility model is related to machinery field, a kind of specifically stud locking mechanism, in especially a kind of nuclear power pump in
The locking mechanism of hexagonal double-ended bolt.
Background technology
In nuclear power pumping unit, due to its internal high temperature hyperbaric environment, while also machine driving, power transmission and signal pass
Defeated demand so that the use environment of pump is relative complex.Therefore, often there are pressure, temperature in the junction of bolt stud in pump
Greatest differences, the generation of oscillation phenomenon occurs often for parts in being pumped under the effect of mechanically operated power, so as to cause bolt
The failure of Stud connection or even stable equipment operation security problems.
The content of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide interior hexagonal double-ended bolt locking in a kind of nuclear power pump
Structure sets locking slot, locking plate and compressor arm including being arranged on the side wall of screw hole, and the locking plate is including hemispherical matrix and
Multiple lock ears of even setting, the centrally disposed location hole of hemispherical matrix；The lock ear is inserted into the locking slot；Compressor arm
End surface shape is consistent with the inner face shape of interior hexagonal double-ended bolt, and the end face of compressor arm sets positioning pin, the outer diameter of the positioning pin
With the diameter matches of location hole；Interior hexagonal double-ended bolt is screwed in the screw hole, and the inner face of interior hexagonal double-ended bolt is abutted with locking plate.
To ensure that with the inner face of interior hexagonal double-ended bolt location conflicts, the inner end of the interior hexagonal double-ended bolt will not occur for positioning pin
Face circle centre position sets groove.
The utility model has the advantages that：Locking effect is good, and stud loose phenomenon will not occur.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the position view of locking slot；
Fig. 3 is the schematic shapes of locking plate；
Fig. 4 is the side view of Fig. 3.
Specific embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, as shown in the figure, the utility model includes being arranged on the side of screw hole 2
Locking slot 3, locking plate 5 are set on wall 1；The locking plate 5 includes hemispherical matrix 52 and the multiple lock ears 51 being uniformly arranged, this implementation
Example also can according to circumstances set multiple for 2, and be uniformly distributed；The centrally disposed location hole 6 of hemispherical matrix 52；The lock
Ear 51 is inserted into the locking slot 3；8 shape of end face of compressor arm 7 is consistent with 10 shape of inner face of interior hexagonal double-ended bolt 4, compresses
The end face of bar sets positioning pin 9, the outer diameter of the positioning pin 9 and the diameter matches of location hole 6；Interior hexagonal double-ended bolt 4 screws in described
In screw hole 2, under the external force effect of locating rod arrow direction along Fig. 1, the inner face 10 of interior hexagonal double-ended bolt is abutted with locking plate.Figure
The semicircle of dotted line is the original state of hemispherical matrix 52 in 1；Due to being raised in screw hole surface, there is provided location hole,
Locking plate is bonded with the inner surface of interior hexagonal double-ended bolt exactly convenient for locating rod.
To ensure that with the inner face of interior hexagonal double-ended bolt location conflicts, the inner end of the interior hexagonal double-ended bolt will not occur for positioning pin
Face circle centre position sets groove.
