Description
Technical field
This utility model is related to auto parts and manufactures angle, and specifically one kind is used for detecting part operating mode under vibrational state
Universal fixturing.
Background technology
Automobile is affected by its own mechanical operating and condition of road surface, inevitably produces and vibrates, all parts of vehicle body,
It is all to spend its life-cycle in vibration, in other words, automobile as an entirety, needs in vibration by using to scrapping.Respectively
Whether individual parts working condition under vibration is stable, durable, determines the reliability of vehicle mass；Each parts
Noise level under vibration, has influence on vehicle and uses the phonoreception level of comfort when driving for the people.In order to detect each zero
Reliability under vibrational state for the part, needs to carry out vibration test to them.In automobile manufacturing enterprise, be all traditionally for
The different special fixture of each different parts design, parts to be measured are fixed on special fixture, are then placed on vibration
Vibration detection is carried out on monitor station.Such special vibrating test fixture, such as Chinese patent literature cn204330254u, in 2015
Disclosed on May 13, in " a kind of automobile radiators water inlet pipe and water outlet pipe strength test device "；Chinese patent literature cn204658251u,
In " a kind of Automobile Door System vibration test fixture " disclosed in 29 days April in 2015；Chinese patent literature cn204314040u,
In " a kind of novel vibrating fixture for inlet manifold vibration test " disclosed in 6 days Mays in 2015；Etc..Such is special to shake
Dynamic test fixture, is corresponded with parts, lacks compatibility, or even the symmetrical part of vehicle body left and right sides is all difficult to general, leads
Cause fixture quantity vast and numerous, the time making fixture is long, costly, management is difficult.Once new parts substitute old parts, with old zero
The special vibrating test fixture of members fits is accomplished by scrapping, and needs to remake new special vibrating again for new parts
Test fixture, this also results in waste.
Utility model content
This utility model technical issues that need to address are that existing General clamp for vibration test poor universality, thus provide
A kind of good General clamp for vibration test of versatility.
To achieve these goals, this utility model adopts the following technical scheme that a kind of General clamp for vibration test, including
Lower end can be fixed on the equipment canned paragraph on vibration test platform, and the upper end of described equipment canned paragraph is connected with part canned paragraph；
The upper end of described part canned paragraph is provided with the part stationary plane being adapted to the fixed bit place face of parts to be tested, described part
Recessed in the middle part of stationary plane it is provided with part fixing threaded hole.
The General clamp for vibration test of the technical program design, generally near cylindrical, including 2 major part, position
In lower section is equipment canned paragraph, and its bottom is provided with stud under equipment canned paragraph, may be inserted into consolidating on vibration test platform
Determine in the hole, and secured fixtures on vibration test platform by the bolt of coupling；Above is part canned paragraph, part
The top of canned paragraph is provided with part stationary plane, can be adapted to the stationary plane around screw on parts to be tested；Part is fixed
Face middle setting part fixing threaded hole, can be threaded connection parts to be tested are fixed on fixture.If part
Fixing threaded hole is mismatched with the fixing threaded hole size on part, it would however also be possible to employ the mode of switching carries out coupling and fixes.By this
The setting of sample, a fixture can be adapted to a fixing threaded hole position of parts to be tested, as long as by parts to be tested
Each fixing threaded hole of same direction same plane position is fixed on a universal fixturing, then these universal fixturings are fixed
On vibration test platform, you can carry out vibration test.Test to the different directions of parts, Different Plane position, then only
Need universal fixturing carries out the connection of limited number of time to respective direction relevant position, you can complete to test.Because the design provides
Be general clamp, can be declined to a great extent with mass manufacture, cost, supply cycle significantly reduces, and is advantageous to chucking tube
Reason.
Preferably, the middle part of described part canned paragraph is provided with gimbal structure.In order to meet further to be tested zero
The coupling to greatest extent of the different angle screws of part, this programme employs gimbal structure at the middle part of part canned paragraph, makes
Part canned paragraph can make 180 ° of rotation on mutually perpendicular 2 directions, forms the different angles of part stationary plane, with suitable
The different angles replacing the spare parts.
Preferably, being connected for spherical hinge between described part canned paragraph and described equipment canned paragraph.This programme employs
Spherical hinge connects, and makes part canned paragraph and the connection of equipment canned paragraph have great degree of freedom, the wildcard effect with parts
More preferably, more screws on parts can once be mated during test, it is possible to reduce the test number (TN) to same parts.
Preferably, the spherical part in spherical hinge is located at part canned paragraph side.Part canned paragraph side is above,
Parts closer in test, and the volume size of spheroid is relatively small, overall structure can be made more stable located at top, has
Help improve test effect.
Preferably, the spheroid shell parts in described spherical hinge are threadedly connected with equipment canned paragraph.This programme
Spheroid shell parts are designed as threadeding with equipment fixing end, separable design is convenient to process and keep in repair, at the trial also
The adaptation that some special angle can be met requires.
Preferably, fixture summation quality is not less than 3:1 with parts mass ratio to be tested.Due in vibration test
Resonance principle, the parts to be tested containing fixture can resonance effect near certain vibration frequency, and serious meeting leads to treat
The damage of test parts was lost efficacy.The gross mass of fixture is increased by this programme, can effectively raise the frequency of this resonance point appearance.
And after this resonance dot frequency is raised, much surmounted the frequency of vibration running into during vehicle reasonable employment, therefore not
Test effect and conclusion can be affected.
In sum, the beneficial effects of the utility model are: versatility is good.
Brief description
Fig. 1 is a kind of structural representation of the present utility model.
Wherein: 1 equipment canned paragraph, 2 part canned paragraphs, stud under 11 equipment canned paragraphs, 21 part stationary planes, 22 parts are solid
