To sum up, the embodiment of the invention provides a headlamp gauge and a detection method of a headlamp, peripheral automobile parts matched with the headlamp are simulated through a profiling surface 21, during detection, the headlamp 5 is firstly positioned on the profiling surface 21, then the headlamp 5 is connected with the headlamp 5 through a vehicle body mounting point 34 on an adjusting device 3, so that the simulated headlamp 5 is mounted with a vehicle body, then a connecting piece 32 is driven to advance or retreat along the axial direction of an adjusting rod 33 through driving the adjusting rod 33, so that the position of the vehicle body mounting point 34 is adjusted, after the position of the vehicle body mounting point 34 is adjusted, the assembly tolerance between the headlamp 5 and the profiling surface 21 is measured, so that the assembly tolerance between the headlamp 5 and the matching surface of the peripheral automobile parts is simulated, and the dependence on the vehicle body when the assembly tolerance between the headlamp 5 and the matching surface of the peripheral automobile parts is measured in the prior art is avoided, thereby effectively improving the detection efficiency. In addition, in the prior art, if the assembly tolerance between the matching surfaces of the front lamp and the peripheral automobile parts is measured under different installation errors of the front lamp and the automobile body installation point, only the front lamp and the different white automobile bodies can be assembled and tested one by one, so that the detection efficiency is low. In addition, the headlamp inspection device provided by the embodiment of the invention can adjust the installation error of the headlamp and the vehicle body installation point 34 in a short time, namely, different vehicle body precision states can be simulated in a large amount in a short time, and the trial-manufacture debugging period is shortened. In addition, the headlamp gauge provided by the embodiment of the invention does not need to be disassembled and assembled for many times when the installation error of the headlamp 5 and the vehicle body installation point 34 is adjusted, and the operation is convenient.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
