Keriotheca is accompanied between the top panel and bottom panel, the bottom panel and top panel are equipped with tight for may pass through
The through hole of firmware, the honeycomb groove of the keriotheca can be embedded in the embedded part for fixing measured piece, and the side of the keriotheca is provided with
Shrouding.
Preferably, the embedded part includes the first embedded part and the second embedded part, and second embedded part is used for and fixed measured piece
Fastener is fixed, and the cavity of first embedded part is used to fix with shaking platform.
Preferably, first embedded part is strip or cylindric.
Preferably, the honeycomb shape of the keriotheca is hexagon, rhombus or rectangle.
Preferably, the cavity inner surface of first embedded part is provided with screw thread.
Preferably, adhesive glue is provided between the keriotheca and bottom panel.
Preferably, the keriotheca is aluminum keriotheca.
The invention has the advantages that：
When the 1st, being directed to the size of test product and being more than vibration table surface, pass through through hole and insertion of the fastener through top panel
In embedded part, that is, complete to fix.Good using the test effect of vibration tong of the present invention, test data is more accurate.
2nd, the setting based on keriotheca, light weight, rigidity are high.

As shown in figure 1, the light high-stiffness vibration tong of the present invention, including bottom panel 6 and top panel 1, the top
Keriotheca 3 is accompanied between portion's panel 1 and bottom panel 6, the bottom panel 6 and top panel 1 are equipped with tight for may pass through
The through hole of firmware, the honeycomb groove 11 of the keriotheca 3（As shown in Figure 3）The embedded part for fixing measured piece, the honeybee can be embedded in
The side of nest layer 3 is provided with shrouding 5.The present embodiment is mainly used in during vibration test, and bottom panel 6 is placed in shake table
On, and fixed with shake table, measured piece is to be fixed on by fastener on top panel 1, passes through top panel 1 and bottom panel
The honeycomb groove 11 of keriotheca 3 between 6 can be embedded in the embedded part for fixing measured piece so that when size is more than the tested of shake table
Part can be also embedded in by fastener by completing fixation in the embedded part in several embedded honeycomb grooves 11, and keriotheca 3 for
Transmit in vibration processes that damping and rigidity effect are good, solve and be directed in the prior art when measured piece size is more than shake table
The technical problem of test effect difference.Wherein, the keriotheca is aluminum keriotheca, further to mitigate vibration tong of the present invention
Quality, when solving product and fixture combination weight in the prior art and exceeding shake table thrust, shake table pushes away hypodynamic technology
Problem.Shrouding 5 includes four shroudings, and shrouding is fixed by adhesive glue and keriotheca 3, to strengthen the honeycomb during vibration test
3 stability between bottom panel and top panel of layer.As the optimization of the present embodiment, the keriotheca 3 and bottom panel 6
Between be provided with adhesive glue so that keriotheca 3 is closely affixed with bottom panel 6.As the optimization of the present embodiment, the keriotheca 3
