Description
Technical field
The present invention relates to testing equipment field, more particularly to a kind of impact wear testing machine.
Background technology
The mechanical property of materials of workpiece refers to the energy of the resistance to deformation that workpiece material showed under external force or destruction
Power generally includes the performances such as intensity, plasticity, elasticity, brittleness, fracture toughness, the hardness of material.Usually, it is new in research and probe
During material, new process, new technology and new construction, service-test machine is required for measure the mechanical property of materials of workpiece, with
Just effectively ensure quality and security reliability of workpiece etc..Therefore, testing machine is widely used in machinery, metallurgical, aviation boat
The industries such as it.
Impact test supports shock proof performance commonly used in measuring material under dynamic loading.Wear test is commonly used in measure
Wear resistance of the material under given friction condition.
For portioned product or material, impacted before being taken into use and wear test is very necessary.With

Under part, operating personnel select corresponding drill bit to be drilled generally according to different engineering-environments, it is thus evident that the material of drill bit in itself
The performances such as abrasion, impact when material selection and construction, directly affect progress and the development of engineering.Therefore, relatively
The mechanical property of materials of drill bit is accurately measured under true experimental enviroment just seems particularly necessary.
It is almost few at present to complete impact and the testing machines of wear test, usually impact and wear test point simultaneously
It is not carried out on different testing equipments；However, part workpiece may be impacted and be worn simultaneously in practical work process,
By impact and abrasion, separately test does not significantly meet actual condition.In addition, although physical presence sub-fraction can be carried out at the same time
Impact and the testing machine of wear test, but there are still problems for such testing machine.For example, during impact test, pendulum is only relied on
Hammer or the loading shock loading such as eccentric block, the shock loading amount of loading is small, and operation is heavy so that can not accurately test piece
Resist impact property.During wear test, the friction condition that workpiece gives differs farther out with actual condition, can not accurately test work
The parameters such as the wear extent and friction coefficient of part.
Therefore, existing testing machine can not provide the relatively impact of actual condition and wear test for workpiece for measurement
Test condition, the accuracy of the mechanical property of materials of measure are poor.

With respect to the background art, impact wear testing machine provided by the present invention including pedestal and is installed on the pedestal
On column, further include the first guide part that is installed on the column and can be vertically moved along the column；With described
The second guide part that one guide part is connected；It is installed on second guide part, the support portion for being used to support workpiece for measurement movement；Peace
It is connected loaded on first guide part and with the top of the support portion, the axial direction for loading axial load for the support portion
Loading unit；It is installed on second guide part and is connected with the side of the support portion, for driving support portion rotation
Rotate loading unit.
Since first guide part is installed on the column, and second guide part and the first guide part phase
Even, therefore second guide part can be realized with first guide part along the column and be vertically moved.Obviously, it is installed on described
The support portion and the rotation loading unit on second guide part can also be realized along the column to be vertically moved.
When the axially loaded portion longitudinal movement that first guide part drive is attached thereto, the institute of workpiece for measurement is installed
It states support portion to vertically move therewith, therefore, the workpiece for measurement being installed on the support portion also can realize longitudinal direction along the column

Similarly, the rotation loading unit can be realized along the column with second guide part and be vertically moved, and institute
The support portion axial rotation can be driven by stating rotation loading unit, and therefore, the workpiece for measurement clamped by the support portion actively revolves
Turn, the sample to be tested to contact or into being positioned on the pedestal makes workpiece for measurement rub with sample to be tested, completes
Wear test.
The axially loaded portion and the rotation loading unit can be oriented to first guide part and described second respectively
Portion realizes along the column and vertically moves, and can simulate workpiece for measurement and not only be hit in actual condition but also frayed operating mode；
Again since the axially loaded portion and the rotation loading unit can be independently by drive controls, therefore workpiece for measurement can be simulated only
It is hit or only frayed operating mode.In addition, the sample to be tested being positioned on the pedestal to be measured can appoint according to actual condition
Meaning is replaced, it is thus possible to the working environment of workpiece for measurement in accurate simulation actual condition.
Further, workpiece for measurement is typically actively to be impacted or worn in actual condition, therefore is entirely being tested
In the process, the axially loaded portion and the rotation loading unit are distinguished actively by the support portion to workpiece for measurement loading axis
To load or spin load, make impact test and wear test relatively practical work by the way of impact and abrasion coupling
Condition.
Therefore, which makes the test condition of impact and the abrasion of workpiece for measurement closer to Practical Project, the material of measure
Expect that mechanical performance is more accurate.
