There are two linear optical axis sliding tracks 3-3;

[0035] The movable block 3 is embedded into the sliding track 1-1 of the vertical scal...

specific Embodiment approach 2

[0038] Specific embodiment two, combine Figure 1 to Figure 6 Describe this embodiment mode, this embodiment mode is the test method of the train lighting irradiation angle test device described in the first specific embodiment, three ways of urban railway car headlight irradiation: two lamps parallel to the rail surface direct irradiation, two lamps parallel to the oblique Downward illumination and two lamps obliquely converge downward to illuminate.

[0039] combine figure 1 a. The illumination mode of train headlights is that two lamps are parallel to the rail surface, and the position of the test device is combined when the headlight illumination angle is tested. figure 2 . In this embodiment, the test device is used to locate and measure the position of the wick of the headlight, and determine the center position of the light beam on the test board when the headlight is turned on. The specific operations are as follows:

[0040]Fix the test device and the test board o...

Abstract

The invention discloses a train illuminator illumination angle testing device and a testing method thereof, relates to the technical field of the train vehicle manufacturing, and solves problems thata current urban subway headlamp illumination angle test is performed by using manual measurement so that a center point of a light beam is not accurately positioned, a detection process is not standard and the like. The train illuminator illumination angle testing device comprises a longitudinal measuring ruler, a horizontal measuring ruler, a moveable block and a sliding aim point. The testing device can be suitable for headlamp position conditions of various vehicle types, has two-dimensional space measurement functions of longitudinal and horizontal measurement on the basis of center pointpositioning, and is capable of overcoming a defect of a single function of a general measuring tool. At the same time, the testing device is provided with a clamping and fixing device suitable for various rail conditions, so the headlamp illumination angle test is more convenient and accurate, product quality is effectively controlled, and traffic safety is guaranteed. The testing device is rational in structure, stronger in adaptation and universality, capable of performing two-dimensional space adjustment according to the different vehicle types and principles, and has a function of bi-directional center point positioning. The testing method is simple, easy to implement.

Description

technical field [0001] The invention relates to the technical field of rail vehicle manufacturing, in particular to a test device and a test method for the irradiation angle of train headlights, which are suitable for testing the irradiation angle of urban railway car headlights. Background technique [0002] At present, there is no standard test method and measuring tool for the test of the illumination angle of headlights of urban railway vehicles, and all methods are manual measurement with a tape measure and visual evaluation. The specific process is: manually measure the height of the headlight wick of the vehicle from the rail surface and the distance between the two headlight wicks, and then measure the same distance on the test board perpendicular to the rail surface and 2-5 meters away from the headlight with the track as the benchmark. And make a mark with a pen, this mark will be used as the center of the beam under the normal illumination of the headlight. There...
