Problems solved by technology

This kind of measurement process is cumbersome, and the measurement work efficiency is low. Moreover, using a tape measure to measure the size to calculate the center position and draw a line, the error caused by this center measurement method is also relatively large, and even the chassis is scrapped due to excessive error.

Abstract

The invention provides an integrated center measurement device for a sleeper beam and a traction beam and a measurement method thereof. The integrated center measurement device for the sleeper beam and the traction beam includes a base, a first rack and a second rack. A center gear rotating relative to the base is mounted on the base and a center mark line is formed between a middle plane passing through the center of the center gear and the base. A first clip is connected to the first rack and a second clip is connected to the second rack. The first rack and the second rack are arranged on two opposite sides of the center gear and are respectively in engaged transmission with the center gear. The first clip and the second clip are disposed on two opposite sides of the center gear. The first rack and the second rack are driven by the center gear, so that the first clip and the second clip are enabled to move symmetrically and synchronously. The center position of the sleeper beam or the traction beam is determined through indication via the center mark line, so that the measurement working efficiency is improved and measurement error is reduced. The measurement device has prominent advantages of being accurate, reliable, simple and convenient in measurement and the like.

Description

technical field [0001] The invention relates to the technical field of integrated corbel and traction beam center measurement technology, in particular to an integrated corbel and traction beam center measuring device and method for marking and detecting the center lines of subway vehicle corbels and traction beams. Background technique [0002] When assembling the bottom frame of the subway vehicle, it is necessary to ensure that the deviation between the centerline of the traction beam, the centerline of the corbel beam and the centerline of the buffer beam does not exceed 2mm. Usually, when installing the underframe at the end of a subway vehicle, it is necessary to draw the centerline of the corbel and buffer beam first, and after the corbel is welded, it is also necessary to perform a flatness test on it. [0003] In the current assembly work, when installing the bottom frame at the end, it is necessary to locate through the centerline of the corbel. The main method is ...
