Abstract

The invention discloses an automobile lamp hole site depth detection device, which comprises a load bearing mainboard, a power supply device arranged on the load bearing mainboard, an indicator light and depth detection craft equipment for metal positive and negative electrodes, wherein, the depth detection craft equipment for metal positive and negative electrodes is connected with the indicator light through a power supply line and forms a circuit with the power supply device. During the detection, whether the depth of an automobile lamp hole site reaches the requirement is judged through the contact state of the detection craft equipment. The invention is suitable for the detection of various automobile lamp hole sites. The automobile lamp hole site depth detection device has the advantages of simple structure, convenient and quick operation and small measurement error.

Description

technical field [0001] The invention relates to an automobile lamp safety detection device, which belongs to the technical field of automobile lamp manufacturing. Background technique [0002] In the manufacturing technology of car lights, in order to ensure driving safety, the sealing performance of car lights is highly required. Usually, the reason that affects the sealing of car lights is mostly caused by the poor sealing of the light adjustment mechanism of the car lights. The reason is that the mechanism needs multiple parts to cooperate with each other. Water in the body will affect the normal light direction of the headlights. Therefore, the installation requirements for this place are relatively high during the assembly process. In order to obtain a higher sealing performance, usually, during assembly, it is necessary to accurately measure the depth of the holes on the plastic lamp housing. At present, the method of measuring the depth of the hole position is to u...
