LOAD CALIBRATION JIG FOR INSTRUMENTATION IMPACT TESTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a load calibration jig for an instrumentation impact testing device, capable of executing high-precision load calibration.;SOLUTION: This load calibration jig for an instrumentation impact testing device is equipped with a horizontal frame 32 mounted on a test piece supporting stand 14 of an impact testing device, and the frame 32 has an inner end 34 for receiving an impact blade 10 of a hammer 8 and an outer end 44 for supporting a hydraulic cylinder 48. A load cell 52 is connected to the piston rod of the hydraulic cylinder 48, and the load cell 52 has a load pad 54 contacted with the back of the hammer 8. By this load calibration jig, the frame 32 is mounted on the test piece supporting stand 14 in the state where the hammer 8 of the impact testing device is hung down freely, therefore respectability of the mounting is easily guaranteed. As the load calibrating jig is supported by the test piece supporting stand 14, the weight is not given to the load cell 52. Preferably the load pad 54 of the load cell 52 is supported through a universal joint.;COPYRIGHT: (C)2000,JPO
