When the laser distance measuring sensor 220 moves, the spatial position thereof changes, and the position of the measured point on the locomotive body 300 also changes, so that the point coordinate information on the surface of the locomotive body 300 can be obtained by continuously measuring the spatial position and the return distance of the sensor.
Specifically, in the present embodiment, the door bracket 210 may be manufactured by using a profile, and specifically may be designed and welded according to the external dimensions of the locomotive body 300.

It should be clearly understood that the principles of the present invention are in no way limited to any of the details of the detection device or any of the components of the detection device shown in the drawings or described in the present specification.
In summary, the invention provides the detection device which is easy to manufacture and low in cost, and can be used for measuring the outline dimension of the locomotive body and the deflection of the whole locomotive, so that the whole-dimension detection of the outline of the locomotive body can be realized, and an accurate outline drawing can be drawn. After the vehicle body is prefabricated for deflection, the device is used for obtaining the outline dimension of the continuous vehicle body so as to obtain the vehicle body deflection data. The device can solve the difficulty that the appearance and deflection data of large-scale products of locomotives can not be detected, and provides a comprehensive data detection solution for vehicle body manufacturing detection.
