The laser of laser transmitter projects is positioned.
The utility model has the advantages that：
The utility model is moved using the controllable loading crossbeam of motor on loading system horizontal guide rail.It can finely tune simultaneously
The position of sliding block is moved horizontally, and then ensures that 4 groups of loading systems are acted perpendicularly on the axis of the sample back side.The utility model
Loading position of the hydraulic stem in testing experiment can be quickly positioned using laser locating apparatus, can be reduced pre- in former working procedure
Load step, effectively improves operating efficiency, and can ensure the loading position degree of accuracy.
Compared with prior art, the utility model can simplify former working procedure, omit preloading step, improve work
The accuracy of loading position can be also provided while efficiency.
