Property and accurate theory analysis and calculating can not be carried out, experimental test method just turn into determine testpieces rigidity unique method.Just
Degree experiment loading equipemtn is divided into common apparatus and special equipment, and common apparatus uses universal testing machine more, and special equipment uses more
Hydraulic cylinder or cylinder are loaded.
Suitable loading system is selected, makes active force caused by it and size, direction and the application point of torque can
The real bearing state of accurate model configuration.Due to the complexity of testpieces structure, design general loading equipemtn and seem outstanding
To be important.
Laboratory, as general support system, makes it play balanced action in the external applied load in structure more from ingot bar.
Accurate model configuration is acted on by force boundary condition.Connection between loading device and ingot bar uses hold-down support, ingot bar more
Connecting hole is mostly regular size, designs a kind of attachment structure being suitable between loading device and ingot bar to meet the requirement of experiment
Common apparatus can reduce the cost of experiment, can also shorten the cycle of experiment.

Connect block structure.
To realize the purpose of this utility model, technical scheme is used by the utility model：One kind is used for loading device
The connecting block structure of base, including two adjustable transfer blocks of the free degree, the first contiguous block and the second contiguous block, described first
Contiguous block includes the first contiguous block elongated hole and the first contiguous block connecting hole, second contiguous block include the second contiguous block elongated hole and
Second contiguous block connecting hole, second contiguous block pass through the supporting construction connecting hole on the second contiguous block elongated hole and supporting construction
It is bolted, second contiguous block is bolted by the second contiguous block connecting hole and the first contiguous block elongated hole,
First contiguous block is bolted by the first contiguous block connecting hole with loading device base.
Wherein, the supporting construction is ingot bar.
Compared with prior art, the beneficial effects of the utility model are：The contiguous block designed by application the utility model
Structure, the connection between loading device and ingot bar can be achieved, so that the loading to two free direction optional positions of testpieces, with
Meet loaded during experiment to testpieces the needs of.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., it both may refer to a certain part and had been directly connected to another part, and can also refer to a certain part and pass through other portions
Part is connected with another part.
It is of the present utility model to devise a kind of adjustable transfer block of two-freedom being connected for loading device with supporting construction,
For providing in stryctyrak test, stiffness test, stability test to testpieces the arbitrfary point on two Free Test directions
Power and torque loading.
As shown in Fig. 1-Fig. 7, the utility model provides a kind of connecting block structure for the base of loading device 3, including
Two adjustable transfer blocks of the free degree, the first contiguous block 4 and the second contiguous block 1, first contiguous block 4 include the first connection
The contiguous block connecting hole 42 of block length hole 41 and first, second contiguous block 2 include the second contiguous block elongated hole 21 and the second contiguous block
Connecting hole 22, second contiguous block 2 are passed through by the second contiguous block elongated hole 21 and the supporting construction connecting hole in supporting construction 1
Bolt connection, second contiguous block 2 are bolted by the second contiguous block connecting hole 22 and the first contiguous block elongated hole 41,
First contiguous block 4 is bolted by the first contiguous block connecting hole 42 and the base of loading device 3.
Wherein, the supporting construction is ingot bar.
, can be with adjusting load device by adjusting the link position of the second contiguous block and supporting construction when use
Position, by the long pore structure of the second contiguous block, position of second contiguous block relative to supporting construction is can adjust, passes through the first connection
Block length pore structure, position of first contiguous block relative to the second contiguous block is can adjust, is realized by above-mentioned adjustment structure to experiment
The loading of part power and torque of arbitrfary point on two Free Test directions.
