The I-shaped base comprises a middle transverse plate and supporting plates at two sides, a threaded hole matched with a screw in a screwed mode is formed in the middle transverse plate, a groove is formed in the center and used for avoiding a detection head, a positioning pin seat is arranged on the front face of the middle transverse plate, a positioning pin is fixedly connected to the lower end of the middle transverse plate, the positioning pin is matched and positioned with a mounting hole formed in the periphery of a rear cover of the door lock actuator, a rear cover of the door lock actuator to be detected is locked on the back face of the middle transverse plate through a clamping block through the screw,
the outline reference block is fixed on one side of the central groove of the middle transverse plate and is opposite to the assembly outline surface of the inner cavity of the rear cover of the door lock actuator to be detected, the distance between the outer peripheral surface of the outline reference block and the assembly outline surface with the standard size is uniform, the go-no go gauge can smoothly slide and pass through the gap, if the gap between the assembly outline surface of the rear cover of the door lock actuator to be detected and the outer peripheral surface of the outline reference block can not smoothly slide and pass through the go-no go gauge, the size is unqualified,
the blind hole reference block is fixed on the other side of the central groove of the middle transverse plate and is opposite to a blind hole of an inner cavity of a rear cover of the door lock actuator to be detected, a through hole in clearance fit with the blind hole through gauge is formed in the blind hole reference block, and whether the blind hole through gauge is matched with a blind hole shaft hole or not is judged to be qualified.
The utility model has the advantages that:
this utensil is examined to profile face and blind hole of lid behind auto parts lock executor can carry out the precision detection to the assembly profile face and the blind hole of lid behind the lock executor, utilizes to lead to no-go gage and carry out the orbit along the assembly profile face and slide and detect whether up to standard of size to make blind hole and blind hole lead to rule shaft hole cooperation, whether qualified with the inspection size, examine a low in manufacturing cost, detection efficiency is high in batches, labour saving and time saving, practical convenient.
