With novel protected range.
Embodiment one
As shown in Figure 1, a kind of bottom backplate universal test device 1, including framework 11 and several clamping mechanisms 12.Wherein,
Framework 11 includes support frame 111 and upper frame 112, and upper frame 112 is mounted on the top of support frame 111, and clamping mechanism 12 is mounted on top
On frame 112.
Specifically, support frame 111 includes four brackets and four stands perpendicular to bracket, four brackets pass through four three
Axis articulation piece 1111 is successively attached, and four stands are mounted on four brackets by four three axis articulation pieces 1111 above-mentioned
Top.Wherein, as shown in figure 5, three axis articulation pieces 1111 include an axle sleeve placed vertically and two horizontal positioned axle sleeves,
A notch is respectively provided on three axle sleeves, there is an interconnecting piece at the both ends of notch respectively；The axle sleeve one end placed vertically opens up
It is fluted, two horizontal positioned axle sleeves be mutually perpendicular to and one end of two horizontal positioned axle sleeves respectively with the axis placed vertically
The vertical connection of set, the other end opens up fluted respectively.Thus, the level that four brackets are mounted on four three axis articulation pieces 1111 is put
Inside the axle sleeve set, four stands are mounted on inside the axle sleeve of aforementioned four three axis articulation pieces 1111 placed vertically, and axle sleeve is cut
The interconnecting piece attachment screw at mouthful both ends tightens bracket and stand, when needing to adjust position, unclamp screw to bracket and
Stand is adjusted.
Upper frame 112 is mounted on the top of support frame 111 by four three axis articulation pieces 1111, upper frame 112 include upper layer and
Lower layer, each layer include four by the sequentially connected bracket of aforementioned three axis articulation piece 1111, several clamping mechanisms 12 difference
Upper layer bracket is mounted on, on lower floor support by two Double pin hinge fittings 1211.
Wherein, clamping mechanism 12 includes clamping arm 121 and clamping head 122, as shown in figure 4, Double pin hinge fitting 1211 wraps
Two orthogonal axle sleeves are included, are hollow inside two axle sleeves.Clamping arm 121 be mounted on two Double pin hinge fittings 1211 its
In inside an axle sleeve, it is another that the upper layer bracket and lower floor support of upper frame 112 are separately mounted to both of the aforesaid Double pin hinge fitting 1211
Inside one axle sleeve, clamping arm 121 can be moved and be rotated along the upper layer bracket and lower floor support of upper frame 112,
Since clamping arm 121 is all installed on four upper layer brackets, four lower floor supports, the present apparatus may be implemented 4
A freedom degree.
