Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present application provides a lens set torsion testing fixture, fig. 1 is a schematic structural diagram of the lens set torsion testing fixture provided in this embodiment, and fig. 2 is an exploded view of the lens set torsion testing fixture provided in this embodiment. Referring to fig. 1 and 2, the lens group torsion testing jig provided in this embodiment includes a body 1 and a positioning assembly disposed on the body 1, an opening is disposed at the top of the body 1, a plurality of first screw holes 11 are disposed on the circumferential surface of the body 1, and the plurality of first screw holes 11 are disposed at intervals around the central axis of the body 1. The positioning assembly comprises a plurality of first screw rods 2, and the plurality of first screw rods 2 are in one-to-one correspondence with the plurality of first screw holes 11. Specifically, each first screw 2 is screwed in the corresponding first screw hole 11, screwing the first screw 2 can move the first screw 2 relative to the first screw hole 11, stopping screwing the first screw 2 can fix the first screw 2 relative to the first screw hole 11, and the plurality of first screws 2 enclose a positioning space for clamping the lens group.

The embodiment provides a lens group torsion test fixture, with camera lens and motor spiro union to a locating position and place body 1 back in, be located the length of body 1 inside first screw rod 2 through the adjustment, thereby the size in adjustment location space, thereby it fixes the lens group to make every first screw rod 2 support the motor tightly, continue the rotatory camera lens again and test, need to correspond the dedicated tool of design and fix to the motor of different models in comparing prior art, lead to complex operation, the lens group torsion test fixture that this application provided, motor to all models is all general, the change time has been saved, and the production efficiency is improved.

Referring to fig. 1, in this embodiment, the body 1 includes four side plates 1 and a bottom plate 5, the four side plates 1 and the bottom plate 5 enclose a rectangular structure with an open top, and the plurality of first screw holes 11 are disposed on the four side plates 1, it is conceivable that the body 1 may also be designed to be circular or annular, and the present embodiment does not limit this.

Further, in the present embodiment, each side plate 1 is provided with a first screw hole 11.

Because the lens and the motor are screwed to a certain position and fixed in the body 1, the lens needs to be continuously rotated for testing, so that the position of the lens in the motor can be changed up and down, the lens possibly protrudes out of the lower surface of the motor, and in order to avoid the lens from striking the bottom plate 5, the lens group is generally suspended in the body 1 in practical application. Therefore, referring to fig. 1 and fig. 2, in the present embodiment, the bottom plate 5 is provided with a second screw hole 12 and a second screw rod 3 matching with the second screw hole 12.
