Abstract
A main board fixing device is provided for fixing main boards with different specifications, and includes supporting bench and a plurality of fixing members capable of moving on the supporting bench. The main board fixing device can be used to fix main boards with at least two different specifications simultaneously, thereby increasing work efficiency and reducing testing cost.
Description
[technical field]
The utility model relates to a kind of stationary installation, particularly a kind of main board fixing device.
[background technology]
For the mainboard that guarantees to assemble has enough reliabilities in transportation, according to client and code requirement, need simulation actual shipment process that mainboard is carried out mechanism's testing authentication, two important test events are vibration-testing checking and shock-testing checking in mechanism's testing authentication.So-called vibration-testing checking is meant mainboard to be measured is placed on the test platform of bobbing machine, the action button of operating described bobbing machine makes the accelerated motion on three-dimensional of described tested mainboard, scanister on the described bobbing machine can be recorded in the vibration situation of mainboard under the different vibration accelerations, and shows the vibration acceleration when vibration is big; Then bobbing machine move these significantly vibration acceleration do the vibration of stipulated number, with the degree of stability of the components and parts on the simplation verification mainboard under the vibration situation.Described shock-testing checking is meant that fixing mainboard to be measured is on the test platform of shock machine, operate described shock machine then and tested mainboard is carried out the shock-testing of each face, the ability to bear when in the actual shipment process, being impacted suddenly with the simplation verification mainboard with the acceleration of stipulating.
When carrying out the checking of above-mentioned two class testings,,, must there be associated anchor to assist and tests so not directly tested mainboard is fixed in described test platform because the mainboard cost that assembles is high and its back side is not exclusively smooth.Please refer to Fig. 1, existing main board fixing device comprises brace table 10 and some screws 14, and tested mainboard 100 is provided with some mounting holes 102.The mounting hole 102 of described brace table 10 corresponding described mainboards 100 is established plurality of fixed double-screw bolt 12.Each screw 14 is threaded in the screw of corresponding double-screw bolt 12 by the mounting hole 102 of correspondence, thereby described mainboard 100 is fixed in described brace table 10.Yet because described double-screw bolt 12 stationkeeping, so a stationary installation can only be used for fixing the mainboard of corresponding with it a kind of specification, the mainboard of different size needs different stationary installations, when the tester tests, just needs the stationary installation of various various criterions.Along with the update of mainboard standard, the mainboard of different size the size and on position of mounting hole all with uncertain, so just make in test process, the problem of suitable stationary device often to occur can not find.
[summary of the invention]
In view of above content, be necessary to provide a kind of mainboard main board fixing device all applicatory at least two kinds of different sizes.
A kind of main board fixing device, described main board fixing device comprise brace table and the plurality of fixed part that can move on described brace table; Described fixture is used for fixing the mainboard of different size.
Compare prior art, this main board fixing device makes same stationary installation can install and fix the mainboard of different size by the plurality of fixed part that can move on described brace table is set.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing and better embodiment.
Fig. 1 is the three-dimensional exploded view of existing main board fixing device and mainboard.
Fig. 2 is the better embodiment of the utility model main board fixing device and the part three-dimensional exploded view of mainboard.
Fig. 3 is the user mode figure of the better embodiment of the utility model main board fixing device.
[embodiment]
Please refer to Fig. 2 and Fig. 3, the utility model main board fixing device is used for fixing mainboard 200, with convenient mainboard 200 is tested, and establishes some mounting holes 202 on the described mainboard 200.The better embodiment of described main board fixing device comprises brace table 20, some support members 30, plurality of fixed part 40 and some screws 50,52 and 54.Described support member 30 and fixture 40 all are fixed in described brace table 20, and described fixture 40 is used for fixing described mainboard 200.
Described brace table 20 is one roughly to be microscler plate body, establishes some screws 22 on it, and its four lateral margin is established some through holes 24 respectively.Four sidewalls of described brace table 20 are established two oblong openings 28 respectively.Two oblong openings 28 of each sidewall are symmetrically distributed with respect to the central shaft of described brace table 20 perpendicular to this sidewall.
Described support member 30 takes the shape of the letter U, and the oblong openings 28 of its corresponding described brace table 20 is established two arms 32, and the through hole 24 of described each arm 32 corresponding described brace table 20 is offered two fixed orifices 34 respectively.
Each fixture 40 is the long strips body with certain altitude, offer a microscler fluting 42 in the middle of it, described fluting 42 is a groove, and the length of described fluting 42 is greater than the screw diameter of described screw 52, so that described fixture 40 can move along the screw rod of described screw 52 or rotate; The size of described fluting 42 is about 4/5 of whole fixture 40.The two ends of described fixture 40 upwards are convexly equipped with a double-screw bolt 44 respectively, establish screw respectively on the described double-screw bolt 44.
When described main board fixing device is installed, respectively two arms 32 of described support member 30 are put into the oblong openings 28 of the corresponding sidewall of described brace table 20, the corresponding through hole 24 that the fixed orifice 34 on its each arm 32 is aimed on the described brace table 20; Described screw 50 passes the through hole 24 on the described brace table 20 and is threaded into corresponding fixed orifice 34 on the described support member 30, is about to described support member 30 and is fixed to described brace table 20.The fluting 42 of described fixture 40 is aimed at the corresponding screw 22 of described brace table 20; Fluting 42 on the described fixture 40 of described screw 52 processes screws togather the corresponding screw 22 to described brace table 20, is about to described fixture 40 and is fixed to described brace table 20.
Fixing described mainboard 200 is when described main board fixing device, unscrewing described screw 52 makes described fixture 40 move or rotate along described screw 52, when the mounting hole 202 of mainboard 200 is aimed at the double-screw bolt 44 of described fixture 40, fix described screw 52 once more described fixture 40 is retightened to described brace table 20; At last, the mounting hole 202 on the described mainboard 200 of described screw 54 processes also screws togather to the screw of described fixture 40 end double-screw bolts 44, is about to described mainboard 200 and is fixed to described fixture 40.
Because described fixture 40 can carry out activity within the specific limits, so described main board fixing device can be used for fixing the mainboard of the vicissitudinous slightly different size of size, has improved testing efficiency, has saved testing cost.
When carrying out the testing authentication of mainboard correlated performance, the described brace table 20 that fixes mainboard 200 is positioned over the test platform of bobbing machine, behind the fixing described brace table 20, the vibration-testing checking that can be correlated with as requested.When carrying out the shock-testing checking, described brace table 20 is positioned over the test platform of shock machine, because each face of mainboard 200 all need carry out shock-testing, so when the shock-testing checking of carrying out four sides, the described brace table 20 stressed stable and uniform of answering, described support member 30 structural symmetry, thus can make described shock-testing checking safety and reliability.
