Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, a kind of composite polycrystal-diamond shock resistance detection device, is driven, motor by motor 1
Frequency-variable controller 2 and pulsed data logger 3 are connected with, for controlling the power of motor 1 and turning for record motor 1
Speed.The rotation of motor 1 is by belt or gear drive to main shaft 15, being provided with disk 4, the edge of disk on main shaft 15
Provided with the fixture 5 for installing composite polycrystal-diamond 6.Composite polycrystal-diamond 6 moves in a circle with disk, make its with
Impact hardness block 11 collides.
Impact hardness block 11 is arranged on one end of impact rotating bar 8, and resistance is provided with the lower section of impact hardness block 11 should
Become chip force cell 12, force cell 12 is transferred data in computer 13.Impact rotating bar 8 is arranged on base 14
