Description
Technical field
The utility model relates to mechanical structure mounting technique fields, and in particular to be a kind of skewed slot locking cap flanging work
Tool.
Background technique
In the in-pile component of pressurized-water reactor, there are a large amount of threaded fasteners.Since working environment is severe, these spiral shells
It is locking that line fastener needs to take the mode of locking cap flanging to carry out.The flanging qualification rate of locking cap directly affects nuclear reactor
Performance.It is limited by the space structure of in-pile component, the structure arrangement of the shape bordering tool of locking slot is more difficult.
In the prior art, oblique foot is welded on cylinder, and after a number of uses, weld can occur significantly to become the tool
Shape, to influence the service life of Forming Quality and tool.
Utility model content
Purpose of the utility model is to solve the above problems, provide a kind of skewed slot locking cap bordering tool, pass through electricity
Spark processing has manufactured the punching press mode structure that the oblique foot of molding and cylinder are linked together, and processing quality is high, long service life.
The technical scheme adopted by the utility model is that:
A kind of skewed slot locking cap bordering tool, characterized in that the bordering tool is cylindrical, including cylinder and force dress
It sets, oblique foot is arranged in the inner wall of barrel front end, and the oblique foot and cylinder are integrally formed, and the oblique foot is oblique with nuclear power product fastener
The position of slot is corresponding, and the cylinder keeps oblique foot down fold mobile under the action of force application apparatus, and the oblique foot is squeezed cup is locked
In backfin side to skewed slot.
Further, bolt is set in the cylinder, and the head of the bolt is hexagon, the Hexagon hole with fastener
Corresponding, when the bolt is engaged to the Hexagon hole of fastener, the oblique foot is positioned into the skewed slot.
Further, cover board is arranged in the bottom of the cylinder, and the bolt bottom is connect by spring with cover board.
Further, connector is arranged in the bottom of the cover board, and the connector is used to cooperate with force application apparatus.
The beneficial effects of the utility model are:
(1) by electrical discharge machining, the punching press mode structure that the oblique foot of molding and cylinder are linked together, processing quality have been manufactured
Height, long service life；
(2) the oblique foot of bordering tool is linked together with cylinder ring side, meets the lesser problem of fastener sizes.
Detailed description of the invention
Attached drawing 1 is the section view of cylinder head；
Attached drawing 2 is A-A cross-sectional view in attached drawing 1；
Attached drawing 3 is the schematic cross-section of locking cap；
Attached drawing 4 is the structural schematic diagram before locking cap flanging.
Label in attached drawing is respectively as follows:
1. bolt；2. spring；
3. cover board；4. bolt；
5. cylinder；6. locking cap；
7. fastener；8. skewed slot；
9. oblique foot.
Specific embodiment
It elaborates with reference to the accompanying drawing to the specific embodiment of the utility model skewed slot locking cap bordering tool.
Referring to attached drawing 3,4, the socket cap of the fastener 7 of nuclear power product is set there are three skewed slot 8, and bordering tool passes through three of them
It, will be in the side flanging to skewed slot 8 that cup be locked when oblique foot 9 is promoted into three skewed slots 8.Locking cap 6 is set not generate pine after locking
It is dynamic.
Referring to attached drawing 1,2, bordering tool includes cylinder 5 and force application apparatus, and oblique foot 9, oblique foot 9 is arranged in 5 front inner wall of cylinder
It is integrally formed with cylinder 5, oblique foot 9 is corresponding with the position of skewed slot 8, and Hexagon hole is equipped among fastener, is arranged in cylinder 5
The head of bolt 1, bolt 1 is hexagon, and corresponding with the Hexagon hole of fastener 7, hexagonal bolt is engaged to fastener 7
When Hexagon hole, oblique foot is positioned to the skewed slot of fastener.Cover board 3 is arranged by bolt 4 in the bottom of cylinder 5, and 1 bottom of bolt is logical
Spring 2 is crossed to connect with cover board 3.Connector is arranged in the bottom of cover board 3, and connector is used to cooperate with force application apparatus, and cylinder 5 is exerting a force
Under the action of device, keep oblique 9 down fold 8 of foot mobile, oblique foot 9 squeezes locking cup in flanging to skewed slot 8.
Referring to attached drawing 1 to 4, bordering tool use process is as follows, the bolt 1 of bordering tool is engaged in fastener 7
In hexagon ring, at this moment, the skewed slot 8 of oblique foot 9 and fastener, which is realized, to be positioned.Force application apparatus puts plus-pressure, between cover board and bolt
Spring, which is compressed, keeps oblique 9 down fold 8 of foot mobile, will be in the side indentation skewed slot that lock cup.When force application apparatus unloads pressure, spring
It resets first, oblique foot is withdrawn from from skewed slot, and bolt is finally exited from the hexagon of fastener, completes to grasp the flanging of locking cap
Make.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the principle of this utility model, these improvements and modifications
Also it should be regarded as the protection scope of the utility model.
