Description
Technical Field
The utility model relates to a solve above-mentioned technical problem, provide a railway vehicle davit processing location frock.
Background
The suspension arm of the railway passenger car is an important component of the bogie of the railway passenger car. In the process of machining the suspension arm of the railway passenger car, the suspension arm of the railway passenger car needs to be positioned. The positioning mode of the traditional rail passenger car suspension arm is as follows: 1. manually marking a line on the suspension arm of the railway vehicle to determine a reference line, 2, supporting the suspension arm of the railway vehicle on a processing platform through a plurality of groups of sizing blocks, and 3, fixing the suspension arm of the railway vehicle on the processing platform through a bolt fastening pressing plate. The traditional positioning mode has the defects of complicated positioning process, low machining efficiency, insecure positioning structure, easy occurrence of machining size deviation due to displacement of the mounting seat of the subway locomotive and low product forming rate.
