Description
Technical field
The utility model is related to a kind of sync response mechanisms being exclusively used in vibration test, belong to military project radiator class product
Envlronmental vibration test control field.
Background technology
When vibration test, fixture is consistent with each point response of testpieces joint face, input stimulus when ensuring experiment
Uniformity.
In actual fixture frequency sweep test, often there is each response point acceleration root-mean-square value and differ greatly or even same
Two test products clamping face response differences apart from each other are larger on fixture, and extreme case will appear part response for forward direction
Amplification, another part response are that negative sense amplifies.This does not occur as soon as in experiment test specimen each point vibration input position vibration level seriously not
Consistent phenomenon and control off-gage phenomenon.
During current vibration test, two side neck of product and installation end need to be fixed by test products normal operation
Face, simplest fixed form are both sides respectively one independent mounting bases of design, fix two side necks, fixture medium design respectively
One independent end face fixed seat.This fixed form often will appear several mounting base Vibration Conditions respectively not phase in vibration test
Together, non_uniform response, experiment is caused to be difficult to control.
Invention content
For the above technical problem, it is structure as a whole mechanism the purpose of this utility model is to provide a kind of main body, this knot
Structure is rigidly good, and supporting and fixing face is angle of release structure, and manufacture easy to process and test products assembly, test products both sides nozzle are fixed
Main body is connected, and response consistency is good.
To achieve the goals above, the utility model uses following technical scheme：
A kind of sync response device for vibration test, including end face fixed seat, left hand fixed seat, right hand fixed seat,
Clamp bottom board and end face positioning component；
The left hand fixed seat, end face fixed seat and right hand fixed seat are sequentially connected to the upper of clamp bottom board according to " Π " shape
On end face, and left hand fixed seat, end face fixed seat, right hand fixed seat and clamp bottom board are structure as a whole；
It is provided with fixing screws in the end face fixed seat；
It is provided with kidney slot corresponding with fixing screws position on the clamp bottom board and on the inside of the fixed seat of end face；
The end face positioning component is detachably connected with clamp bottom board.
To divide face equally symmetrical about end face fixed seat vertical for the left hand fixed seat, end face fixed seat and right hand fixed seat.
It is provided with the reinforcement being connected with clamp bottom board on the outside of the left hand fixed seat, end face fixed seat and right hand fixed seat
Muscle.
The left hand fixed seat and end face fixed seat junction outside and end face fixed seat and right hand fixed seat junction
Outside is each provided with a reinforcing rib being connected with clamp bottom board.
The left hand fixed seat is connected by screw with left clamping position component.
The right hand fixed seat is connected by screw with right clamping position component.
For welding structure product since welding deformation is inevitable, each testpieces size has different.Vibration tong
It needs that each testpieces can be completely fixed, considers for production cost, it is impossible to manufacture a set of vibration for each testpieces
Fixture, therefore left hand fixed seat is designed as seperated knot with left clamping position component, right hand fixed seat and right clamping position component
Structure, to adapt to different sized products, when use, only needs to change left and right clamping position component, and fixed seat is without needing to change.It is left
Clamping position component and right clamping position component belong to the conventional design of this field, it is required that being that manufacturing cost is relatively low, but has
Certain regulating power, position can lock after adjusting, and guarantee will not be loosened in vibration test.
The advantage of the utility model compared with prior art is：
1. the design of the main fixed component of testpieces, fixture base, two side neck fixed components is structure as a whole, and here one
Body structure refers to whole, the non-structure being detachably connected；
2. structural weak position increases reinforcing rib, left hand fixed seat, end face fixed seat and right hand fixed seat are according to " Π " shape
Connection forms three sections of meander line structures, and rigidity reinforcing is carried out in each section of outside and broken line junction；
Increase fixture accessibility (operable facility 3. being opened by clamp bottom board screwing corresponding position and hiding hole (kidney slot)
Property).

Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but claimed range is not
It is confined to content described in the present embodiment.
As shown in Figures 1 to 3, to avoid two side neck fixed seats, end face fixed seat occurs vibrating inconsistent, the utility model
The design of this three parts fixed mounting is structure as a whole and forms entirety with clamp bottom board, is i.e. left hand fixed seat, end face is fixed
Seat and right hand fixed seat are sequentially connected according to " Π " shape, and vertical two-by-two, reduce the inconsistent possibility of structural response to greatest extent,
End face positioning component 6 is then detachably connected by attachment screw and clamp bottom board, and left hand fixed seat, end face fixed seat pass through screw
2 are respectively connected with left clamping position component 3 and right clamping position component 4.Left clamping position component 3 and right clamping position component 4
Test products are clamped as shown in Fig. 2, can translate and realize by adjusting bolt or so.
1 end face fixed seat of jig main body, left hand fixed seat, right hand fixed seat, clamp bottom board, as shown in Figure 6 and Figure 7, end
The end face stationary plane inclination angle of face fixed seat determines that angle of release structure ensures that it is easy to add by test products actual use installation angle
Work manufactures and testpieces installation (angle of release refers to that jig main body positioning surface is more than 90 degree with bottom surface angle in Fig. 7).Such as Fig. 4, to protect
Card lower section fixing screws 5 (fixing screws 5 are for fixing testpieces) is not blocked by testpieces and can not be tightened, and 4 are opened on clamp bottom board
A kidney-shaped hides hole, is put in from below convenient for metal plate hand and tightens fixing screws 5.
As shown in Figure 4 and Figure 5, maximal support component of the end face stationary plane as test products, where end face fix
Seat improves its rigidity of structure by three, back side reinforcing rib, increases the aluminum design threaded hole longevity with installation steel-wire screw-socket
Life.Steel-wire screw-socket bottom outlet processing length and dimension precision requirement are reduced by way of increasing lower section 4 and hiding hole.
Such as Fig. 4, to avoid being mounted on fixture pilot test products, end face fixed seat, two side neck fixed seats pass through " Π "
Shape structure combines as a whole, and (left and right in top corner part (left and right side fixed seat and end face fixed seat junction), bearing forced position
Side fixed seat) increase the reinforcing rib increase rigidity of structure.
