Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 2 to 4, the device for detecting a countersunk hole of a front cover of a camera barrel of the present invention includes a testing box 10, a plurality of movable conductive posts 20, an insulating mounting plate 30, a plurality of connecting posts 40, a plurality of fixed conductive posts 50, a plurality of springs 60, a testing circuit, and an alarm.

The top surface of the top plate of the test box 10 is provided with a test groove 11 with a shape matched with that of the ear hanging piece 100 to be tested, the test groove 11 is provided with a first through hole corresponding to the counter bore 110 of the ear hanging piece 100, and the movable conductive column 20 is slidably located in the first through hole. The top end of the movable conductive column 20 protrudes out of the first through hole, and a truncated cone-shaped test curved surface 21 is arranged on the circumferential edge. The bottom end of the movable conductive post 20 protrudes below the top plate. A metal clamping convex ring 22 is protrudingly arranged on the circumferential side wall of the movable conductive column 20 close to the bottom end.

The insulating mounting plate 30 is horizontally positioned inside the test box 10 and is fixedly connected with the bottom surface of the top plate through a plurality of connection posts 40. The insulating mounting plate 30 is provided with a second through hole corresponding to the movable conductive pillar 20, and the fixed conductive pillar 50 is fixedly located in the second through hole.

The gap is preferably 2 mm.

The insulating sleeve 51 serves to isolate the spring 60 from the fixed conductive post 50, and since the insulating mounting plate 30 is made of an insulating material, the spring 60 does not electrically connect the movable conductive post 20 and the fixed conductive post 50.

If the countersunk hole 110 and the inner curved surface 111 of the ear hanging piece 100 are regular, the movable conductive pillar 20 will not move downward when the ear hanging piece 100 is placed in the testing groove 11, and the testing curved surface 21 and the inner curved surface 111 are perfectly matched.
