The invention discloses a hole site detection device for an
automobile safety air bag shell. The hole site detection device comprises a bottom plate, a
workbench, a clamping mechanism, a positioning column, a lifting mechanism, a driving frame, a sliding table, a hole site detection mechanism and a hole
diameter detection mechanism. The
workbench is used for placing a workpiece, the position of the workpiece is fixed through the clamping mechanism, the positioning column is matched with a center hole of the workpiece for positioning, and the lifting mechanism controls the positioning column to ascend and descend so as to achieve clamping and discharging. The sliding table is installed on the driving frame and controlled by the driving frame to move left and right, and
station switching between the hole site detection mechanism and the hole
diameter detection mechanism is achieved. The hole site detection mechanism drives a hole site detection pin to descend to detect the hole site of the workpiece through a second electric telescopic rod, if the hole site is qualified, the hole site detection pin is smoothly inserted, otherwise, a
pressure sensor identifies an unqualified
signal; the sliding block and the adjusting block are matched with the guide rail and the lead screw to ensure stable movement of the sliding table, the guide plate is used for automatic discharging after detection, and double detection of the hole site and the hole
diameter of the workpiece is achieved.
