Lever ratio measuring device and lever ratio measuring method

Abstract

The invention provides a leverage ratio measuring device and a leverage ratio measuring method. The lever ratio measuring device includes a telescopic rod assembly, a guide rod and a sliding sleeve; the telescopic rod assembly includes two end rod bodies and a middle rod body, the middle rod body is located between the two end rod bodies, and the two ends of the middle rod body are respectively slidably connected On the corresponding end rod body, the side of each end rod body is provided with a first positioning pin, the guide rod is fixed on the middle rod body, the guide rod is provided with a scale line, and the sliding sleeve is sleeved on the guide rod. Rotate and slide on the guide rod, the side wall of the sliding sleeve is formed with a jack, the jack is slidably provided with a bracket, the bracket is formed with a pin hole, and the slidable pin hole is provided with a second positioning pin; the first positioning Measuring marks are respectively arranged at the centers of the end faces of the pin and the second positioning pin. The leverage ratio measuring device is used to facilitate the measurement of the operator, reduce the difficulty of measurement and improve the measurement accuracy.

Description

technical field [0001] The invention relates to measuring equipment, in particular to a leverage ratio measuring device and a lever ratio measuring method. Background technique [0002] At present, rail vehicles are widely used in people's daily travel and cargo transportation, and the rail vehicle bogie is one of the important components. The braking mechanism in the bogie usually includes a lever and a connecting rod. The two ends and the middle of the lever are respectively provided with bushing holes, and the axes of the three bushing holes of the lever are in the same plane, and the two ends and the middle of the connecting rod are also Bushing holes are respectively provided, however, the axes of the bushing holes at both ends of the connecting rod are located in the same plane, while the axes of the bushing holes in the middle of the connecting rod and the axes of the bushing holes at both ends are vertically located in different planes. When assembling and debugging...

AI Technical Summary

Problems solved by technology

The existing technology usually uses a three-dimensional liner to measure the lever and connecting rod, but in the actual measurement process, it is necessary to measure the center of the bushing hole on the lever and connecting rod. It is difficult to determine the center, and the measurement accuracy Low, and because the bushing holes on the connecting rod are not on the same plane, the connecting rod needs to be leveled and aligned, and the operation process is cumbersome
