Description
Technical field
The present invention locking plate locking for Allen bolt in counterbore.
Background technique
Reactor coolant pump is unique rotating machinery in pressurized-water reactor nuclear power plant primary Ioops, is the heart of nuclear power station, is used
To convey the reactor coolant of regulation flow.Hydraulic part in core main pump, is limited by bulk and structure, is filled mutually
Timing relies on counterbore and Allen bolt to be attached more.
For the Allen bolt installed in this counterbore, traditional screw retention mode is unable to satisfy core main pump hydraulic
The locking requirement of component.Such as using spring washer, anti-loose ability is unable to satisfy requirement.For another example there is the locking pad of tooth pattern
Piece, anti-loose ability can satisfy requirement, but its meeting disfiguring workpiece, leave tiny pit in the deep gouge bottom surface of workpiece counterbore, difficult
Cleaning easily accumulates the radioactive substance in coolant, is not allowed to.And routine has ear type locking plate to be limited by bulk
System, can not install and use in counterbore.
Summary of the invention
The object of the present invention is to provide a kind of locking plates locking for Allen bolt in counterbore, are not damaging assembly zero
Under the premise of part, enough anti-loosening properties are provided.The technical solution of the present invention is as follows: the middle part of locking plate (1) is the piece of domes
Body (2)；A pair of of lock ear (3) are symmetrically arranged at the both ends of sheet body (2)；Circular hole (4) are equipped in the middle part of sheet body (2).
Working principle of the present invention:
Allen bolt of the present invention for installing in counterbore before installation locking plate (1), needs first in the deep gouge of workpiece counterbore
Edge symmetrical machining two shallow depth, semicircular mounting grooves；It is the arch sheet body (2) of specific arc, arch in the middle part of locking plate (1)
Structure can reduce the spacing of both ends lock ear (3), make locking plate (1) that can smoothly be put into the deep gouge of counterbore；Lock ear (3) is symmetrical cloth
The semicircular structure set.Circular configuration is conducive to be cooperated with mounting groove, and whens assembly and disassembly plays the role of guiding and is not easy to scratch work
Part surface.It is arranged symmetrically position when being conducive to locking plate (1) installation to fix, and bidirectionally limited can provide higher anti-loosening property；Circular hole
(4) resistance when observing the position of locking plate (1) with respect to Allen bolt when being used to install, and reducing deformation；It installs locking plate (1)
When, locking plate (1) is put into the deep gouge of counterbore, makes sheet body (2) arch upward, the Hexagon hole of circular hole (4) and Allen bolt
Centering after lock ear (3) is directed at counterbore mounting groove direction, places locking plate (1) to the top of Allen bolt；Outer-hexagonal will be had
The center of special installation tool alignment circular hole (4) of head, with hammer installation tool upper end, the part that sheet body (2) is arched upward
It pounds to the cylinder end surface with Allen bolt and develops, and Allen bolt is protruded into circular hole (4) and peripheral portion deformation
Hexagon ring simultaneously develops, and locking plate (1) and Allen bolt are relatively fixed at this time.Sheet body (2) pound it is flat after cause structure to stretch, make to lock
Ear (3) protrudes into counterbore mounting groove, and locking plate (1) and counterbore are relatively fixed, and locking plate (1) installs at this time.Counterbore mounting groove passes through
Lock ear (3) limits locking plate (1) displacement, and locking plate (1) and socket head screw are relatively fixed, turn to limit Allen bolt
It is dynamic, play locking effect.When locking plate (1) is installed and after installation, only lock ear (3) is contacted with the mounting groove of workpiece counterbore, therefore not
It can disfiguring workpiece other surfaces.And it is latent to install groove depth, and close to workpiece outer end face, and it is easy to clean, avoid incrustation.
By the size and thickness of change sheet body (2), lock ear (3) and circular hole (4), the locking plate of plurality of specifications can be processed
(1), with the Allen bolt suitable for plurality of specifications.
The technology of the present invention effect:
Distinguishing feature of the invention is: can be packed into workpiece counterbore, under the premise of not disfiguring workpiece, provide enough
Anti-loosening property；Structure is simple, is readily produced manufacture, good economy performance；It is applicable to the Allen bolt of plurality of specifications；It is easy to pacify
Assembly and disassembly.
Detailed description of the invention:
Fig. 1 is the front schematic view of locking plate
Fig. 2 is the side schematic view of locking plate
Diagrammatic cross-section when Fig. 3 is the installation of locking plate
Specific embodiment:
As shown in Fig. 2, a kind of locking plate locking for Allen bolt in counterbore, the middle part of locking plate 1 is domes
Sheet body 2；A pair of of lock ear 3 is symmetrically arranged at the both ends of sheet body 2；Circular hole 4 is equipped in the middle part of sheet body 2, as shown in Figure 1.
As shown in figure 3, installation locking plate 1 when, locking plate 1 is put into the deep gouge of counterbore, makes 2 arch of sheet body upward, circular hole 4 with it is interior
The Hexagon hole centering of hexagon-headed bolt after lock ear 3 is directed at counterbore mounting groove direction, places locking plate 1 to Allen bolt
Top；By the center of the special installation tool alignment circular hole 4 with outer-hexagonal head, with hammer installation tool upper end, by piece
The part that body 2 arches upward, which is pounded to the cylinder end surface with Allen bolt, develops, and circular hole 4 and peripheral portion deformation protrude into interior six
The hexagon ring of hex bolt simultaneously develops, and locking plate 1 and Allen bolt are relatively fixed at this time.Sheet body 2 pound it is flat after cause structure to be stretched
Exhibition, makes lock ear 3 protrude into counterbore mounting groove, locking plate 1 and counterbore are relatively fixed, and locking plate 1 installs at this time.Counterbore mounting groove passes through
Lock ear 3 limits locking plate 1 and is displaced, and locking plate 1 and socket head screw are relatively fixed, to limit Allen bolt rotation, rises
To locking effect.
By the size and thickness of change sheet body 2, lock ear 3 and circular hole 4, the locking plate 1 of plurality of specifications can be processed, to be applicable in
In the Allen bolt of plurality of specifications.
When needing to dismantle locking plate 1, straight screwdriver can be used, insertion locking plate 1 is embedded in the bottom of Allen bolt part
, using the counterbore edge of workpiece as impetus, locking plate is prized from Allen bolt and mounting groove by specific angle in portion
Out.
The function of 1 various pieces of locking plate and effect are:
Sheet body 2: it for the domes of specific arc, can reduce the spacing of both ends lock ear 3, put locking plate 1 smoothly
Enter in counterbore.
Lock ear 3: for the semicircular structure being arranged symmetrically.Circular configuration is conducive to be cooperated with mounting groove, and whens assembly and disassembly plays
It the effect of guiding and is not easy to scratch workpiece surface.It is arranged symmetrically and is conducive to position when locking plate 1 is installed and fixes, and bidirectionally limited can provide
Higher anti-loosening property；
Circular hole 4: resistance when observing position of the locking plate 1 with respect to Allen bolt when for installing, and reducing deformation.
