Description
Technical field
This utility model is related to vibration test field, particularly a kind of vibration test fixture.
Background technology
Vibration test refer to evaluation product in expected use environment vibration resistance and to vibrated in kind or model
The test for carrying out.Sine vibration test and random vibration test two are divided into vibration test according to the type of the oscillating load for applying
Kind.Sine vibration test includes quota vibration test and scanning sine vibration test.Scanning vibration test requires that frequency of vibration is pressed
Certain rule changes, and such as linear change or exponential law change.Vibration test is mainly environmental simulation, and test parameterss are frequency model
Enclose, vibration amplitude and duration of test runs.Impact of the vibration to product has：Structural failure, such as malformation, product crackle or disconnected
Split；Product function fails or performance is overproof, and such as loose contact, relay misoperation are made, and this destruction is not belonging to permanent damage,
Because once vibration reduces or stops, work just can recover normal；Manufacturability is destroyed, such as screw or connector loosening, sealing-off.
Vibration test generally realizes that test products are connected with vibration table by test fixture by vibration mechine, from
And the vibrational energy on vibration table is delivered on product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of vibration test fixture, can be effective
Fixed testee.
The purpose of this utility model is achieved through the following technical solutions：A kind of vibration test fixture, it includes bottom
Plate and portable plate, described portable plate is 2N, and N is positive integer, and first through hole, described activity are provided with described base plate
Plate includes riser and transverse slat, and the second through hole is provided with transverse slat, and riser is fixedly connected with transverse slat, and portable plate is solid by the second through hole
It is scheduled on base plate, installing hole is provided with described riser, testee is fixed between two portable plates by installing hole.
Into the multiple first through hole of queue arrangement on described base plate.
Described riser is at right angles fixedly connected with transverse slat.
Described riser is provided with reinforcement with the right angle bearing of transverse slat.
Described portable plate connects first through hole by screw and the second through hole is fixed on base plate.
Described base plate is fixed on a vibration table by screw Jing first through hole.
The beneficial effects of the utility model are：The invention provides a kind of vibration test fixture, clamp bottom board arrangement through hole,
Movable Board position can be adjusted, while through hole is also used for fixture fixing on a vibration table, multiple portable plates are used cooperatively, two-by-two will
Testee is fixed, and structure is more stable, effectively prevents testee during vibration test from coming off.
