Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamp detection equipment, and in particular to a lampshade detection device which is convenient for replacing a vehicle lamp detection socket. Background Art

[0002] Automobile headlights have multiple functions such as lighting and warning lights. In addition to their functions, they also have strict requirements on the appearance after installation on the body. For example, the fit between the installed headlights and the body sheet metal needs to have a uniform gap to ensure the appearance. The part that the installed headlights and the body sheet metal touch is the lampshade, so it is particularly important to test the lampshade of the assembled headlights.

[0003] At present, the commonly used method for detecting the size of a headlight cover is to use a detection fixture, which includes a positioning fixture and a detection fixture that can be raised and lowered relative to the positioning fixture. After the positioning fixture positions the assembled headlight, the detection fixture descends relative to the positioning fixture, and the measurement on the detection fixture is used to measure the position to be detected around the headlight cover. However, when it is necessary to replace the detection fixture for detecting another headlight, it is necessary to separate the positioning fixture from the detection fixture one by one and transport them out by slings. The replacement process is cumbersome and time-consuming. Summary of the invention
