The train coupler buffer is a complex key stressed component with a complicated structure, comprising a buffer beam, bolster beam, and a traction beam/ draw beam. After manufacturing, more than 20 dimensions and positional tolerances/geometric tolerances of the coupler buffer need to be inspected. Currently, manual inspection methods are commonly used, resulting in low efficiency and poor accuracy./ inefficiency and imprecision.

Inspection Object：Train coupler buffer, with a total length of about 4 m and a width of about 2.6 m.

Technical Requirements：Inspection time ≤ 30 minutes, accuracy requirement ≤ 0.1mm.

Measurement Equipment：AutoScan™ 5000.

Measurement Process：Measurements are automatically conducted based on a pre-planned measurement path, without the need for markers.The entire process of data measurement and processing is fully automated.

 3D Inspection of Train Coupler Buffer

Partial Data Inspection Report

Case Summary：In this case, the AutoScan™ 5000 measurement system was utilized, which consists of a measurement probe, robot arm, linear guide, and precision turntable. The entire measurement process took 28 minutes, and the overall measurement accuracy surpassed 0.1mm.
