Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings；
As shown in Figure 1 and Figure 2, a kind of Hopkinson experiment concrete sample device for grinding, including base 1, is provided with base 1
Motor 2, slide rail, the fixture that workpiece can be clamped, cooling device, workpiece 5, provided with the grinding abrasive disk group for polishing test specimen on slide rail
Part 6, is provided with grinding abrasive disk protective cover 7 on grinding abrasive disk.
Slide rail 3 includes upper horizontal direction slide rail 31, lower horizontal direction slide rail 33 and vertical direction slide rail 32.Upper horizontal direction
Slide rail 31（There are two）Two ends be separately fixed on the upper support frame at two ends, lower horizontal direction slide rail 33（There is 1）It is fixed on
In the lower bracing frame at two ends.
Vertical direction slide rail 32 is arranged on horizontal direction slide rail 31 and lower horizontal direction slide rail 33 and is connected to water
Square between slide rail 31 and lower horizontal direction slide rail 33, upper horizontal direction slide rail 31 is parallel with lower horizontal direction slide rail 33, erects
Nogata is vertical with upper horizontal direction slide rail 31 and lower horizontal direction slide rail 33 to slide rail 32, and vertical direction slide rail 32 can be in upper level
Direction slide rail 31 on lower horizontal direction slide rail 33 with horizontally slipping；Frosted wheel assembly is arranged on vertical direction slide rail 32, is passed through
The position of artificial left and right adjusting vertical direction slide rail 32, the test specimen position polished needed for making in the run trace and workpiece of grinding abrasive disk 61
Put holding point-blank.
Motor 2 is arranged on base 1, and motor 2 drives walking device 62 to be walked back and forth in vertical direction slide rail 32, while band
Dynamic grinding abrasive disk 61 is polished test specimen.
Frosted wheel assembly 6 includes walking device 62 and grinding abrasive disk 61, and grinding abrasive disk 61 can be adjusted with height up and down during polishing
The height of grinding abrasive disk 61, makes the minimum point of grinding abrasive disk 61 and the upper surface of workpiece 5 and fixation, and motor 2 drives walking device 62 in cunning
Walked on rail 32, while driving grinding abrasive disk 61 to carry out circulation polishing to workpiece, so can polish one group in the very short time
Test specimen, improves operating efficiency.
Grinding abrasive disk protective cover 7 is arranged on grinding abrasive disk 61, in order to prevent having spark to spill in bruting process, to the people on periphery
Damage.
Cooling device 8 includes storage tank 81, aqueduct 82 and shower nozzle 83, and storage tank 81 is placed on base 1 and uses water guide
Pipe 82 is connected with shower nozzle 83, in test specimen bruting process, due to rubbing action, and the surface temperature of grinding abrasive disk 61 increases, by polishing
