Calibration device for rolling wear testing machine

Abstract

The invention relates to a calibration device for a rolling wear test machine. The problems of the rolling wear test machine that the human factors are great and the measuring accuracy is poor in a wear test can be effectively solved. The technical scheme is as follow: a force transducer is arranged on an upper fixing seat, and a spiral adjusting knob is arranged on a force sensing element of the force sensor; a hanger is suspended at the lower end of the spiral adjusting knob through a pull rope, and the force borne by the hanger can be transferred to the force sensor through the pull rope and the spiral adjusting knob, so that a suspension type force measuring structure is formed; a horizontal two-dimensional platform is arranged on a base below the hanger, and a revolution speed sensor is arranged on a support through a plastic hose. The calibration device provided by the invention has the advantages of easiness in production and operation, convenience in installation, and high measuring accuracy, the force measuring structure can be three-dimensionally adjusted, the load measuring accuracy is the same at different times and different places when different people perform measurement, and a speed measuring system has relatively high measuring accuracy and stability, so that the rolling wear test machine can be used for effectively tracing and verifying.

Description

technical field [0001] The invention relates to measuring equipment in the fields of measurement, measurement and inspection, in particular to a rolling wear testing machine calibration device, which is used for checking the performance index of the rolling wear testing machine, which is a surface trace method testing equipment. Background technique [0002] At present, the rolling wear testing machine is only calibrated with a calibration plate in the requirements of the national standard. There are no specific requirements for the test load and speed indicators, and there are no rolling wear testing machine calibration devices and other products and achievements in the public information. description of. [0003] The daily use of the existing rolling wear testing machine is to adjust the load by increasing or decreasing the weight, but the specific load size and deviation cannot be measured, and it is impossible to test with the existing equipment, because the installation...
