Abstract
The utility model discloses a camera lens detection tool, camera lens detection tool is the disk, and its disk outer lane is equipped with the external screw thread that is used for connecting the detection projecting apparatus, is equipped with the boss at its disk center, be equipped with the circular hole of placing that is used for placing the camera lens on the boss, place the hole and be located the disk axis, the radial cross section diameter of placing the hole is not more than the radial cross section diameter of camera lens, it is equipped with the retaining ring that is used for supporting the camera lens bottom surface to place the hole bottom. The utility model discloses on inserting the camera lens detection tool along placing the hole with the camera lens when detecting, the camera lens with place for transition or interference fit between the hole, guaranteed the camera lens and place the axiality precision between the hole, make the camera lens can not drop easily simultaneously, the camera lens bottom offsets the location with the retaining ring, only need during the dismantlement with the camera lens along placing the hole extract can, promoted the efficiency of change camera lens in the camera lens testing process.
Description
Technical Field
The utility model relates to a camera lens detects technical field, in particular to camera lens detection tool.
Background
The optical lens is an essential component in a machine vision system and directly influences the quality of the imaging quality of the optical system.
For the imaging effect of inspection optical lens, optical lens need carry out the projection on the camera lens detects the projector and detect, generally be equipped with on the projector with camera lens assorted detection tool, fix the camera lens spiro union on the projector, when the camera lens that awaits measuring is changed in the dismouting at every turn, all need rotatory camera lens to install the camera lens, pull down, influence the work efficiency of camera lens testing process, be unfavorable for the big batch detection of camera lens.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a camera lens detection tool overcomes above-mentioned defect, makes the dismouting of camera lens on detection tool more convenient, promotes the efficiency that the camera lens detected.
To achieve the above object, the solution of the present invention is: the utility model provides a camera lens detection tool, camera lens detection tool is the disk, and its disk outer lane is equipped with the external screw thread that is used for connecting the detection projecting apparatus, is equipped with the boss at its disk center, be equipped with the circular hole of placing that is used for placing the camera lens on the boss, place the hole and be located the disk axis, the radial cross section diameter of placing the hole is not more than the radial cross section diameter of camera lens, it is equipped with the retaining ring that is used for supporting the camera lens bottom surface to place the hole bottom.
Furthermore, a retaining shoulder is arranged at one end of the external thread, which extends in the thread direction.
After the technical scheme is adopted, the beneficial effects of the utility model reside in that: the center of the disc-shaped lens detection jig is provided with a boss, the boss is provided with a circular placing hole for placing a lens, the placing hole is located on a disc-shaped axis, the diameter of the radial section of the placing hole is not larger than that of the radial section of the lens, the bottom of the placing hole is provided with a retaining ring for abutting against the bottom surface of the lens, the lens detection jig is screwed on a lens detection projector, the lens is inserted into the lens detection jig along the placing hole and is in transition or interference connection with the placing hole, so that the lens cannot fall off easily, the bottom of the lens abuts against the retaining ring, the lens is installed, the lens is only required to be pulled out along the placing hole during disassembly, and the lens replacing efficiency in the lens detection process is improved.
