Description
Technical field
The present invention relates to a kind of pressure-loaded experimental rigs, and in particular to a kind of small tonnage multi-path pressure load test dress
It sets, belongs to material mechanical performance test device technical field.
Background technology
Currently, material mechanical performance mainly is tested to obtain by Material Testing Machine.But for large scale, production especially to be measured
There is the whole sample of certain radian, traditional Material Testing Machine single-point load test method to be difficult to exist to entire product on product surface
Stress after packaging fastening carries out simulation test research.
Invention content
It is an object of the invention to overcome the deficiencies of existing technologies, one can be had to large scale and surface by providing one kind
The whole sample for determining radian carries out the small tonnage multi-path pressure load testing machine of pressure-loaded experiment.
The invention is realized in this way：
A kind of small tonnage multi-path pressure load testing machine, including four load sensors, four load sensor peaces
On mounting frame for sensor, on mounting frame for sensor, it is additionally provided with product mounting platform, on load sensor top
It is provided with connecting hole, is additionally provided with cambered surface pressure head above product mounting platform, there are four through-hole, cambered surface pressures for setting on cambered surface pressure head
Head is connect by the load screw across through-hole with the connecting hole on load sensor top.
Further scheme is：
The load sensor is S type load sensors.
Further scheme is：
The S types load sensor, the maximum load of each are no more than 5kN.
Further scheme is：
There are four holes for setting on the product mounting platform, for installing large scale band cambered surface product.
Further scheme is：
Specification that there are many radians of the cambered surface pressure head, and it is identical as the radian of specimen surface.
The load testing machine of the present invention passes through independent load sensor respectively by the way of four groups of screw locks
Loading force is transferred to data processing terminal, is studied with simulating the stressing conditions after the product with cambered surface fastens in the case.This hair
It is bright by designing loading structure and measurement method, it can be achieved that pressure simulation uniform load of the large scale with cambered surface product.Device is whole
Body maximum load power 20kN, has four independent loads and Measurement channel, and the pressure that can meet the small tonnage multichannel of product adds
Load and measurement demand.
Description of the drawings
Fig. 1 is the small tonnage multi-path pressure load testing machine overall structure diagram of the present invention；
Fig. 2 is that the small tonnage multi-path pressure load testing machine of the present invention installs connection diagram.
Specific implementation mode
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
As shown in attached drawing 1,2, a kind of small tonnage multi-path pressure load testing machine, to realize adding for small tonnage test force
It carries and measures, the higher S types load sensor 4 of repeatable accuracy, the maximum load of each sensor is selected to be no more than 5kN.Device
In, S types load sensor 4 is fastenedly connected with mounting frame for sensor 5 using the screw of M12, and the independent measurement of four groups of composition is single
Member, then four measurement units are fastenedly connected with product mounting platform 3 using the screw of M3.Install connection type as shown in Fig. 2,
Screw length can be selected according to actual conditions.
In use, four that are placed on product mounting platform 3, and pass through bottom large scale band cambered surface product to be measured
Mounting hole is fixed, and to prevent during the test, because of stress position offset occurs for product.It then, will be with product surface radian
Matched cambered surface pressure head 1 be mounted on product on, at this time, it should be ensured that four through-holes of cambered surface pressure head 1 respectively with S type load sensors
4 connecting holes are substantially aligned.Then, then by four load screws 2 pass through the through-hole of cambered surface pressure head 1 and S types load sensor 4 respectively
Connection.Screw connection is installed successively using offside, it is ensured that product uniform stressed.
After installing, you can by slowly tightening four 2- load screws, realize to large scale band cambered surface product simulation
The uniform load of pressure.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferable embodiment, embodiment of the present invention are not limited by the above embodiments, it should be appreciated that people in the art
Member can be designed that a lot of other modification and implementations, these modifications and implementations will be fallen in principle disclosed in the present application
Within scope and spirit.
