Description
Technical field
The present invention relates to securing member field tests, especially relate to a kind of external threads self-lock nut vibration test work
Dress.
Background technology
Plain nut is female thread, and external screw thread nut is mainly used in the fastening of the bearing of airspace engine, in aviation, boat
Its engine art receives extremely wide application.In view of the particularity of its use environment is it is desirable to external threads self-lock nut energy
In the case of enough dithers producing in engine operation, fastening still can be kept not get loose, this requires external screw thread certainly
Split nut after processing it is necessary to carry out vibration test, to simulate true high frequency situations, detection external threads self-lock nut locking
Performance.However, the vibration tool of routine is only applicable to female thread self-locking nut mostly, there is presently no one kind on the market and can be used for
The test tool of external threads self-lock nut vibration test.
Content of the invention
It is an object of the invention to provide a kind of external screw thread self-locking that can be used for the detection of external threads self-lock nut anti-loosening property
Nut vibration test frock.
In order to solve the above problems, the external threads self-lock nut vibration test frock of the present invention employs the following technical solutions:
External threads self-lock nut vibration test frock, including housing, vibrating shaft and vibration nut, described housing be provided with for vibration
The connecting seat that machine is fixedly connected, vibrating shaft is radially movable be assemblied in set installing hole on housing and with installing hole
Hole wall gap coordinates, and the rear end of vibration nut is provided with turn edge, its rear end and the spacing cooperation of housing, vibrating shaft plug-in mounting from front to back
Vibration nut in and pass through its front end set by outer turn edge with vibrate nut anti-falling cooperation, vibrate nut front portion be provided with for
With the cooperation of tested nut thread so that tested nut compresses the female thread of vibrating shaft, the rear end of vibrating shaft is provided with for being prevented with housing
The stop member of de- cooperation, in the presence of stop member and vibration nut, vibrating shaft can radially vibrate it is impossible to take off vertically
Shrinking away from theshell body.
Described vibrating shaft is hollow axle.
Described stop member is vibration packing ring, and vibration packing ring is provided with bolt corresponding with the flange connecting hole on vibrating shaft
Hole, vibration packing ring is fixed together by hexagon socket head cap screw with vibrating shaft.
Described housing is plate-shaped.
When in use, first vibrating shaft is inserted in vibration nut, then by tested nut (external screw thread self-locking spiral shell
Female) it is screwed in vibration nut and vibrating shaft is loaded, vibrating shaft is inserted in set installing hole on housing, finally by peace
Dress stop member is to prevent vibrating shaft from coming off from housing, thus just a vibratile condition can be provided for tested nut, finally
By the connecting seat of housing, package unit is fixed on corresponding bobbing machine and just can carry out external screw thread self-locking nut anti-looseness
The detection of energy.
Further, the weight of frock can be mitigated as vibrating shaft using hollow axle, due to the body specification of aviation nut
Larger, weight is extremely heavy, and the loss of weight of frock can avoid manufacturer and specially be bought to equivalent due to the nut of a certain model
The bobbing machine of journey, reduces the cost of manufacturer；The housing of tabular is also for the weight mitigating frock.

Specific embodiment
The embodiment of external threads self-lock nut vibration test frock, as shown in figs 1-9, including housing 11, vibrating shaft 12, shakes
Dynamic nut 13 and stop member.
Housing 11 is overall plate-shaped, and the housing 11 using tabular is weight in order to mitigate frock, to reduce to bobbing machine
The requirement of range.Its underpart is provided with connecting seat, is respectively equipped with fork pockets 111 at the two ends of connecting seat, by penetrating in fork pockets 111
Foundation bolt just can achieve to housing 11 to the fixation vibrating machine worktable.The top of housing 11 is provided with installing hole 112, installing hole
112 are available for vibrating shaft 12 insertion radially activity, and in the present embodiment, installing hole 112 specifically uses on above-below direction
Elongated hole, after being inserted in installing hole, vibrating shaft 12 can move back and forth along the vertical direction.
The front end of vibrating shaft 12 be provided with outer turn edge 121, in the present embodiment, vibrating shaft 12 is hollow axle, and it is actually
