Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
This application provides a kind of torsion type cup type locking plate locking fixtures, form locking mode, the application instead of tapping
So that cup type locking plate is squeezed locking, and can control the size for applying extruding force, to ensure that cup type locking plate 7 and locking screw
The uniformity of female 6 circumferential gaps, and improve the reliability and consistency of cup type locking plate locking.
As shown in Figures 2 to 4, the torsion type cup type locking plate locking fixture of the application can be applied to aero-engine center biography
Dynamic cup type locking plate locking.The torsion type locking fixture of the application is mainly made of retainer 1, drive disk 2, connecting rod 4 and backform 3.
Wherein, retainer 1 has a positioning ring 11, and positioning ring 11 and 5 small―gap suture of central transmission bevel gear cooperate, and plays the work of centering
With retainer 1 offers radial along positioning ring 11 there are also a guide plate 12 vertical with 11 axis of positioning ring on guide plate 12
The guide groove 13 of setting.Drive disk 2 is coaxially arranged with positioning ring 11, and is clearance fit with retainer 1, can be in retainer
It rotates in a circumferential direction on 1.The same side of guide plate 12 is arranged in backform 3 and positioning ring 11, and one end passes through guide groove 13, in metallic channel
It can be slided in 13.Connecting rod 4 is hingedly arranged between backform and drive disk, can drive backform 3 can be with by rotating drive disk 2
It is free to slide along the metallic channel 13 on retainer 1, cup type locking plate 7 is pressed into the locking slot of locking nut 6.
Wherein, hinged in above-mentioned connection structure can be attached using the modes such as connecting pin or bolt.
In this application, connecting rod 4 uses two-period form structure comprising first connecting rod 41 and second connecting rod 42, first connecting rod
Hinged between 41 and second connecting rod 42, first connecting rod 41 and backform 3 are hinged, and second connecting rod 42 and drive disk 2 are hinged.Although connecting rod
4 are also able to achieve the above-mentioned function in the application using one-part form structure, but clamping stagnation, therefore the application arbitrarily occur for one-part form structure
In use two-period form structure.
In this application, there is the polygonal hole 21 with 11 axis collinear of positioning ring among drive disk 2, be used for mounting torque
Spanner.In some embodiments, polygonal hole 21 can be one of equilateral triangle, square and regular hexagon.In this Shen
In figure embodiment please, polygonal hole 21 is square structure.
In this application, backform 3 has a boss 31, and boss 31 and the locking slot of locking nut 6 match.Wherein, convex
Obtained by platform 21 can cut for a cylindrical structure with the angled phase of a plane.In some embodiments, certain angle is logical
It is often 10 degree~20 degree.In the present embodiment, angle is 15 degree.
In this application, the quantity of connecting rod 4, guide groove 13 and backform 3 is consistent, and quantity be it is multiple, multiple connecting rods 4 are led
It is uniformly distributed with the axis of positioning ring 11 to slot 13 and backform 3.For example, having 30 locking slots for needing to compress in locking nut 6, then
The quantity of above-mentioned component can be 5, uniformly distributed with the axis of positioning ring 13, therefore can be by using 6 times (rotation is adjusted 5 times) originally
The compacting of all locking slots can be completed in the locking fixture of application.
Preferably, the quantity of connecting rod 4, guide groove 13 and backform 3 is even number.The above-mentioned component of even number can suppressed
It is symmetrically used in journey, pressing process is stablized.Embodiment in illustrations is two situations.
The working principle of the torsion type cup type locking plate locking fixture of the application are as follows: drive disk 2 is rotated by torque wrench,
Connecting rod 4 is driven to move, one end that connecting rod 4 is connect with drive disk 2 is moved with drive disk 2, and the other end of connecting rod 3 pulls backform 3
Movement, due to there is guide groove 13, backform 3 can not do circumferential movement, be only capable of diameter under the action of connecting rod 4 along positioning ring 11
It is final to squeeze cup type locking plate 7 to movement.
In use, operator is by torque wrench to driving for the torsion type cup type locking plate locking fixture of the application
Disk 2 applies torque, makes drive disk 2 counterclockwise or rotates clockwise, and drive disk 2 drives backform 3 to transport radially inward by connecting rod 4
It is dynamic, it is contacted with cup type locking plate 7, continues to power, backform 3 is squeezed with cup type locking plate 7, until cup type locking plate 7 and locking screw
The locking slot of mother 6 is bonded completely, reversely rotates drive disk 2, and backform 3 moves radially outwards, and backform 3 and cup type locking plate 7 are de-
From the locking of cup type locking plate 3 is completed.In above process, not only make backform 3 while squeezing the locking of cup type locking plate 7, guarantee has been locked
It can control loading moment at the uniformity of rear cup type locking plate 7 and 6 circumferential gap of locking nut, while by torque wrench, guarantee
The coupling mechanism force of cup type locking plate 7 is controllable, improves the reliability of cup type locking plate locking and the consistency of operator's operation.
When the torsion type cup type locking plate locking fixture of the application is due to squeezing the molding of cup type locking plate, locking mode locks cup type
Piece is deformed along fiber flow direction directional spreding, is reduced concentrated stress, is improved the fatigue strength of cup type locking plate, solves percussion
Molding locking mode causes cup type locking plate stress to concentrate serious problem, and the tool structure of the application it is simple, it is easy to process,
Just with operation, reliability is higher, cost is relatively low, it is easy to accomplish and be widely applied.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
