Abstract
The invention relates to the field of fastener testing, in particular to an external-threaded self-locking nut vibration test tool. The external-threaded self-locking nut vibration test tool comprises a housing, a vibration shaft and a vibration nut, wherein a connecting seat fixedly connected with a vibration machine is arranged on the housing, the vibration shaft is radially and movably assembled in an installing hole formed in the housing and is in clearance fit with the hole wall of the installing hole, an inner folded edge is arranged at the rear end of the vibration nut, the rear end of the vibration nut is matched with the housing in a limiting mode, the vibration shaft is inserted into the vibration nut from front to rear and is matched with the vibration nut through an outer folded edge arranged at the front end of the vibration nut in an anti-fall mode, inner threads for being matched with a tested nut in a threaded mode so as to enable the tested nut to press the vibration shaft are arranged at the front portion of the vibration nut, a blocking part for being matched with the housing in an anti-fall mode is arranged at the rear end of the vibration shaft, and the vibration shaft can vibrate in the radial direction and cannot break away from the housing in the axial direction under the effects of the blocking part and the vibration nut. The external-threaded self-locking nut vibration test tool can be used for looseness prevention performance detection of external-threaded self-locking nuts.
Description
Technical field
The present invention relates to fastening piece field tests, particularly relate to a kind of external threads self-lock nut vibration test frock.
Background technique
Plain nut is internal thread, and outside thread nut is mainly used in the fastening of the bearing of airspace engine, receives apply very widely in Aeronautics and Astronautics engine art.In view of the particularity of its Environmental Conditions, under requiring the dither situation that external threads self-lock nut can produce when engine operation, still can keep fastening not get loose, this just requires external threads self-lock nut after processing, vibration test must be carried out, with Reality simulation high frequency situations, detect the anti-loosening property of external threads self-lock nut.But conventional vibration tool is only applicable to internal thread self-locking nut mostly, does not also have a kind of test tool that can be used for external threads self-lock nut vibration test at present on the market.
Summary of the invention
The object of the present invention is to provide a kind of external threads self-lock nut vibration test frock that can be used for external threads self-lock nut anti-loosening property and detect.
In order to solve the problem, external threads self-lock nut vibration test frock of the present invention is by the following technical solutions: external threads self-lock nut vibration test frock, comprise housing, vibratory shaft and vibration nut, described housing is provided with the connecting base for being fixedly connected with shaking machine, vibratory shaft radial mobilizable to be assemblied in mounting hole set on housing and with the hole wall Spielpassung of mounting hole, vibration nut rear end be provided with in turn edge, its rear end coordinates with housing is spacing, vibratory shaft to be inserted into from front to back in vibration nut and to be turned edge by outer set by its front end and vibrate nut anti-falling and coordinate, the front portion of vibration nut is provided with and makes tested nut compress the internal thread of vibratory shaft for coordinating with tested nut thread, the rear end of vibratory shaft is provided with the stop member for coordinating with housing anticreep, under the effect of stop member with vibration nut, vibratory shaft can radially vibrate, housing can not be departed from vertically.
Described vibratory shaft is hollow shaft.
Described stop member is for vibrating packing ring, and vibration packing ring is fixedly assemblied in vibration by screw and puts.
Described housing is tabular.
When in use, first vibratory shaft is inserted in vibration nut, then tested nut (external threads self-lock nut) is screwed into and vibrates in nut and vibratory shaft is loaded, vibratory shaft is inserted in mounting hole set on housing, come off from housing to prevent vibratory shaft finally by installation stop member, thus just can be tested nut a vibratile condition is provided, package unit is fixed on the detection corresponding shaking machine just can carrying out external screw thread self-locking nut anti-looseness performance by the connecting base finally by housing.
Further, adopt hollow shaft can alleviate the weight of frock as vibratory shaft, because the body specification of aviation nut is comparatively large, weight is extremely heavy, the loss of weight of frock can avoid manufacturer buys reciprocity range specially shaking machine due to the nut of a certain model, reduces the cost of manufacturer; The housing of tabular is also the weight in order to alleviate frock.
