Abstract

The invention relates to the technical field of a detecting device, particularly to a radian detecting device comprising a pedestal, a positioning member, a proportional amplifying mechanism, and a digital display radian instrument. The positioning member installed on the pedestal is used for supporting a to-be-detected workpiece. The proportional amplifying mechanism includes a measuring rod thatcan rotate relative to the pedestal. The measuring rod has a measuring end and a pressing and abutting end; the measuring end can be in contact with the lower surface of the to-be-detected workpiece;and the distance between the pressing and abutting end and a rotating supporting point is larger than the distance between the measuring end and the rotating supporting point. The digital display radian instrument is used for realizing the contact with the pressing and abutting end; and after the to-be-detected workpiece applies forces on the measuring end, the pressing and abutting end is drivento apply forces on the digital display radian instrument. According to the radian detecting device, because the distance between the pressing and abutting end and the rotating supporting point is larger than the distance between the measuring end and the rotating supporting point, the value detected by the digital display radian instrument is multiplied by a proportion of distances between the two ends of the measuring rod and the rotating supporting point, so that the measurement range of the radian detecting device is increased.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to an arc detection device. Background technique [0002] Carbon skateboard is an important part commonly used in electric locomotives, electric light rails and subways. Its working environment is likely to cause carbon skateboards to fail. Once it fails, it will seriously endanger driving safety. Therefore, its performance must meet the design requirements to ensure that electric locomotives Wait for stable operation. [0003] The manufacturing process of carbon skateboards requires high requirements, especially the matching of carbon strips and aluminum brackets. Therefore, the detection of the processing arcs of carbon strips and aluminum brackets is very important. The curvature detection devices commonly available on the market cannot meet this demand well. The measurement range is not large enough. Contents of the invention [0004] Therefore, the technical probl...
