IMPACT LOAD TESTING DEVICE FOR STATOR GUIDE RAIL-PLUNGER ASSEMBLY OF INNER CURVE MOTOR

The invention relates to the field of inner curve hydraulic motor testing, in particular to an impact load testing device for stator guide rail-plunger assembly of inner curve motor, mainly comprising a control display terminal, a testing system, an oil path and a high-pressure oil source, wherein the testing system and the oil path are both installed on a testing platform; the control display terminal is electrically connected with the testing system, controls the testing system to work and receives data transmitted by the testing system; the high-pressure oil source provides high-pressure oil for the testing system through the oil path; and the testing platform is also provided with an inner curve guide rail specimen and a driving linear motor. The inner curve guide rail specimen is installed at the lower end of the testing system and connected with the driving linear motor. The invention solves the problems that the existing test depends on the whole machine test bench, the control is complicated, the use and maintenance cost are high, and the test accuracy is insufficient.
