Gauge for measuring size of bogie side frame

Abstract

The invention provides a gauge for measuring the size of a bogie side frame. The gauge comprises a gauge body which is of a hollow cylinder structure, a first detection contact device, a second detection contact device and a spring bearing surface measuring device. The first detection contact device and the second detection contact device are disposed at the two ends of the gauge body respectivelyand simultaneously extend in the same direction which is perpendicular to the length direction of the gauge body and away from the gauge body; the spring bearing surface measuring device is providedwith a measuring support and a spring bearing surface measuring rod, wherein the measuring support is disposed in the middle of the gauge body and extends in the extending direction of the first detection contact device and second detection contact device, the surface of the spring bearing surface measuring rod is provided with scale lines, the spring bearing surface measuring rod is arranged at the end, away from the gauge body, of the measuring support, and the moving direction of the spring bearing surface measuring rod is perpendicular to the direction of the measuring support. The gauge for measuring the size of the bogie side frame has the advantages that the operation steps are simple, the adjustment flexibility is high and repeated leveling is not needed.

Description

technical field [0001] The invention relates to the technical field of bogie size measurement, in particular to a measuring tool for measuring the size of a side frame of a bogie. Background technique [0002] Railway wagons are mainly used to transport various goods, and its running part—the bogie is the key component of railway wagons. In order to meet the requirements of high-speed and heavy-duty railway freight, the key is to develop and adopt high-speed wagon bogies. With the development of science and technology, the structural characteristics of bogies are also constantly changing. There are many types of bogies commonly used at present. Among them, the cross-braced bogie has the advantages of simple structure, firmness and good load balance. The bogies mainly used in current trucks, such as turning K 1 Type bogie, turn K 2 Type bogie and turn K 6 type bogies etc. Since the cross-braced bogie is a large-scale component produced in large quantities, when the manufa...
