Technical Field

[0001] The utility model relates to the technical field of automobile parts testing, in particular to a multi-station headlight mask impact resistance test bench. Background Art

[0002] The lamp cover of a vehicle headlight is the primary protective component of the vehicle headlight. If the strength of the headlight fails to meet the requirements due to unqualified manufacturing processes, the impact resistance and fatigue resistance of the lamp cover will be reduced, and it is extremely easy to be damaged during the use and transportation of the lamp cover. Therefore, the impact resistance detection of the manufactured vehicle headlight lamp cover is one of the essential steps.

A protective shell is provided at the top end of the base, and a movable door is provided on the front end face of the protective shell. The support cross plate is movably installed up and down inside the protective shell through a height adjustment module. A through hole for the steel ball to pass through is provided through the support cross plate. A driving module for pushing the steel ball to the through hole is provided at the top end of the support cross plate; during use, first place the glass to be tested between two clamping plates, then rotate the threaded rods on both sides to drive the clamping plates on both sides to slide towards the middle, clamp the glass in the middle, and make it located directly below the through hole. Then, drive the support cross plate to slide up and down through the height adjustment module to fix it at the height to be tested. Then place the steel ball in the middle of the pusher, close the movable door, and turn on the switch of the second driving member through the controller. The second driving member extends, pushing the steel ball to slide towards the side close to the through hole until the steel ball falls from the through hole and hits the headlight mask glass to be tested downward. When the glass breaks, the residue can be swept into the collection tank and then fall into the slag collection tank from the collection tank, and the slag collection tank can be pulled out for centralized treatment.
