Abstract
The utility model belongs to self-locking nut technology, and in particular to a kind of supporting plate self-lock nut locking property test fixture.The utility model supporting plate self-lock nut locking property test fixture includes sample placing groove, clip base, bolt stabilization hole and fixture clamp column.Wherein, the sample placing groove setting is in clip base end, and bolt stablizes hole and is arranged among sample placing groove and gos deep into inside clip base, and the fixture clamp column is arranged in clip base end.Wherein, the sample places groove shape and size is matched with supporting plate self-lock nut to be tested, therefore the utility model supporting plate self-lock nut locking property test fixture perfectly solves the problems, such as that concentricity deviates during the test for equipment, fixture, sample and experiment bolt in practical applications, and the stability and accuracy of test data are improved, there is very high practicability.
Description
Technical field
The utility model belongs to self-locking nut technology, and in particular to a kind of supporting plate self-lock nut locking property test fixture.
Background technology
According to GB 943-1988《Self-locking nut technical conditions》, need to carry out supporting plate self-lock nut locking property experiment item
Mesh.Its test principle is：Self-locking nut is screwed on experiment bolt, back-outs 15 complete cycles.Self-locking nut is from being screwed into
Point precession is completely screwed into the period to terminal is screwed into, for one；Self-locking nut retreats to from starting point rotation is back-outed and back-outs terminal, is one
Completely back-out the period.Back-out and can be carried out continuously from being screwed into the 15th time for the first time in experiment, velocity of rotation will uniformly be put down
Surely.The temperature of self-locking nut must not add 25 DEG C higher than environment temperature, but self-locking nut temperature at most must not exceed 50 DEG C.
However supporting plate self-lock nut is different from common self-locking nut appearance, compared to common self-locking nut, supporting plate self-locking spiral shell
Female both ends are ellipse rather than regular polygon.If testing center using common self-locking nut locking property test fixture pair
Supporting plate self-lock nut carries out locking property experiment, and there are gaps between supporting plate self-lock nut meeting and fixture, are each recycled in nut
Being threaded into of period will produce vibrations when starting to back-out after being screwed into terminal, the authenticity of test data be influenced, since fixture is
Left and right communication type, experiment bolt and the concentricity of supporting plate self-lock nut and testing equipment will produce offset, then 15 when experiment
In cycle, since the temperature that constantly can relatively make nut of concentricity is higher than 50 DEG C；If concentricity can make examination when deviating excessive
Bolt fracture is tested, brings certain danger, problem above that supporting plate self-lock nut locking property can tested to testing crew
Test data is invalid or does not meet mark requirement, and bolt will produce big degree abrasion and can not reuse (a spiral shell
Bolt can be only done a supporting plate self-lock nut locking property experiment) and cause to waste.
Utility model content
Purpose of utility model：There is provided one kind can effectively improve supporting plate self-lock nut locking property test data accuracy and
The fixture of stability.
Technical solutions of the utility model：A kind of supporting plate self-lock nut locking property test fixture comprising sample placing groove,
Clip base, bolt stablize hole and fixture clamp column, wherein the sample placing groove is arranged in clip base end, and bolt is steady
To determine hole to be arranged among sample placing groove and go deep into inside clip base, the fixture clamp column is arranged in clip base end,
Wherein, the sample places groove shape and size is matched with supporting plate self-lock nut to be tested.
It is smooth blind hole that the bolt, which stablizes hole,.
The fixture clamp column is square column.
Sample placing groove axial depth is at least more than 3 times of thickness of supporting plate self-lock nut.
The advantages of the utility model and effect：The utility model supporting plate self-lock nut locking property test fixture by with support
The precise match of crab bolt perfectly solves equipment, fixture, sample and tests bolt during the test in practical applications
The problem of concentricity deviates, and the stability of test data is improved, there is very high practicability.And an experiment bolt can
Three to four supporting plate self-lock nut locking property experiments are completed, a large amount of unnecessary wastes are saved.
Description of the drawings
Fig. 1 is the utility model supporting plate self-lock nut locking property test fixture front view；
Fig. 2 is the utility model supporting plate self-lock nut locking property test fixture side view,
Wherein, 1- samples placing groove；2- clip bases；3- bolts stablize hole；4- fixture clamp columns.
Specific implementation mode
The utility model is described in further detail below.
Please refer to Fig. 1 and Fig. 2, the utility model supporting plate self-lock nut locking property test fixture includes that sample is placed
Slot, clip base, bolt stablize hole and fixture clamp column.Wherein, the sample places groove shape and size and support to be tested
Plate self-locking nut matches, and is arranged in clip base end, the supporting plate self-lock nut for being clamped, to be tested.In addition, the sample
Placing groove axial depth is at least more than 3 times of thickness of supporting plate self-lock nut, so as to effectively avoid during the test, supporting plate
Self-locking nut, which is back-outed, to fall off.
Bolt stablizes hole and is arranged among sample placing groove and gos deep into inside clip base, and it is smooth blind which, which stablizes hole,
Hole, and it is located at axle center, the bolt for supporting plate self-lock nut is placed, and the concentricity during guarantee test.
The fixture clamp column is square column, is arranged in clip base end, to be connect with testing machine.
Before the experiment of the utility model supporting plate self-lock nut locking property test fixture, the concentricity of first Adjustment Tests equipment,
Fixture, experiment bolt are first connect with testing equipment again, then experiment bolt is screwed into manually in supporting plate self-lock nut sample, is adjusted
It will be in sample placing groove in the placement of supporting plate self-lock nut sample and fixture after good position.If supporting plate self-lock nut sample can be easily
It places and explanation in fixture sample slot：Equipment, fixture, sample and experiment bolt concentricity are good, if supporting plate self-lock nut sample
It cannot easily place and in sample placing groove, only should be noted the inclined of supporting plate self-lock nut sample and fixture sample placing groove in fixture
Shifting amount, fine tuning testing equipment will test bolt location and carry out adjustment up and down.By verification experimental verification, which uses simplicity,
Each parameter is satisfied by the requirement of experiment during the test, and effectively increases the stability and accuracy of test data.
