The invention provides an air-tightness detector for a front combination headlamp of a car. The air-tightness detector comprises an upper die (6), a lower die (10), a machine frame (5), an air cylinder I (2), an air cylinder II (8) and airtight heads (12). The upper die (6) and the lower die (10) are arranged in the middle of the machine frame (5). The upper portion of the upper die (6) is provided with the air cylinder I (2). The air-tightness detector is characterized in that the lower portion of the upper die (6) is provided with a plurality of airtight heads (12) connected with an air outlet hole of the air cylinder I (2), an upper lamp is installed on a limiting block (11), the airtight heads (12) on the upper die (6) and an air inlet in the upper die (6) press a corresponding hole in the lamp downwards, and the airtight detector inflates the lamp through the air inlet to carry out airtight detection. According to the airtight detector, the motion of pistons of the air cylinders is matched with the airtight detector to finish airtight detection of the front combination headlamp, so that the working procedure is simplified, the work efficiency is improved, and human-caused errors are reduced.
Description
technical field [0001] The invention relates to the detection of automobile lamps, in particular to an airtight detection machine for automobile front combined headlights. Background technique [0002] In order to prevent the short circuit caused by water ingress during the use of the lamp, the air tightness test of the lamp has become an indispensable inspection process before the lamp leaves the factory. The known air-tightness testing process after the assembly of the front combined headlights of automobiles is generally completed by a manually operated air-tightness detector. Since there are four air intake holes in the front combination headlight of the car, when testing, the worker first blocks three of them with air-tight heads, and then connects the remaining air intake holes to the air-tight detector. The air pump uses 12KPa air to inflate the lamp for 3 seconds and then maintains the pressure for 3 seconds, and then detects the leakage value of the air pressure in...
