Referring to fig. 1-3, an embodiment of the present utility model provides a variable aperture optical lens clamping tool 100, which includes a fixing base 110, a plurality of fins 120, and a supporting member 130. The fixing base 110 is hollow and formed with a mounting hole 110a for mounting an optical lens and a plurality of sliding grooves on an inner wall of the fixing base 110 and communicated with the mounting hole 110a, and the sliding grooves are arranged around the center of the mounting hole 110 a. The fins 120 are slidably disposed in the sliding grooves, respectively, and the fins 120 are used for clamping the optical lens. The supporting member 130 is detachably disposed on the fixing base 110 and is opposite to the mounting hole 110a, and is used for supporting the optical lens when the optical lens is mounted or dismounted.

Before clamping the optical lens, the supporting member 130 and the fixing base 110 are assembled, so that the supporting member 130 is opposite to the mounting hole 110 a. The optical lens is then placed on the support 130 and the fins 120 are locked such that the fins 120 abut against the optical lens to complete the clamping of the optical lens.

When the optical lens clamping tool 100 is used, the supporting member 130 is detached from the fixing seat 110, so that other works such as processing and detection can be conveniently performed.

When the optical lens is disassembled, the supporting member 130 and the fixing base 110 are assembled again, so that the supporting member 130 is positioned below the optical lens. The fins 120 are then urged away from the center of the mounting holes 110a to disengage the optical lens from the grip of the fins 120 and the optical lens falls back onto the support 130.

Compared with the prior art, the optical lens clamping tool 100 provided by the embodiment solves the problem that the existing tool can only clamp the optical lens with a specific size through contraction of the fins 120, and solves the problem existing in the application of the fins 120 through the design of the supporting piece 130.

It should be understood that there are various ways to detachably connect the support 130 to the fixing base 110, for example, by bolting, which is not limited only herein.

Referring to fig. 1-3, in one embodiment, the fixing base 110 is provided with a mounting member 140 for placing the supporting member 130, and the supporting member 130 is disposed between the mounting member 140 and the fixing base 110.

In this embodiment, only the supporting member 130 needs to be placed on the mounting member 140, so that the operation is convenient and the cost is relatively low.

Furthermore, the mounting member 140 and the fixing base 110 may be integrally formed, or may be connected by a stud, or may be welded or soldered.

In one specific embodiment, as shown in fig. 3, the mounting member 140 includes an extension portion 142 extending away from the fixing base 110 and a placement portion 144 at an end of the extension portion 142 away from the fixing base 110, and the mounting member 140 is placed on the placement portion 144.

By adopting the structure of the mounting member 140 provided in this embodiment, only through the two components of the extension portion 142 and the placement portion 144, the structure is simple, the manufacturing cost is relatively low, and the requirement of placing the supporting member 130 can be met.

Further, the length of the extending portion 142 is slightly greater than the width of the supporting member 130, so as to clamp the supporting member 130 between the placing portion 144 and the fixing base 110.

In a more specific embodiment, as shown in fig. 2, the end surface of the supporting member 130 away from the fixing seat 110 is protruded to form a limiting block 132, and the limiting block 132 is used to abut against the side surface of the placement portion 144.

Thus, when the supporting member 130 is assembled, if the limiting block 132 abuts against the placing portion 144, the supporting member 130 reaches a proper position, which is convenient for the operator to operate, and reduces the possibility of error.

Preferably, the number of the mounting members 140 is two, and the mounting members are respectively located at two sides of the fixing base 110. In this way, the support 130 can be more stably mounted on the mounting member 140.

Referring to fig. 1 and fig. 2, in another embodiment, the fixing base 110 is further provided with a plurality of columns 150, and the columns 150 and the mounting member 140 are located on the same end surface of the fixing base 110.

In this embodiment, the number of the columns 150 is three, and the three columns 150 are uniformly distributed around the center of the mounting hole 110 a.

By adopting the optical lens clamping tool 100 provided in this embodiment, compared with using the mounting member 140 as a supporting structure, the structure is more stable, and the phenomenon that the optical lens leaves the supporting member 130 due to the instability of the fixing seat 110 in the assembling or disassembling process is reduced.

In one embodiment, as shown in fig. 2, the end of the supporting member 130 near the fixing base 110 is protruded to form a bump 134, and the optical lens is supported on the bump 134.

It will be appreciated that there is a height of the clamped optical lens from the support 130. In this embodiment, only by the structure of the middle portion of the protruding support 130, the height of other portions is not required to be increased, so that the weight of the support 130 and the cost of consumed materials can be relatively reduced.

Preferably, the tab 134 is located in the middle of the retainer 130.

With continued reference to fig. 1 and 2, in yet another embodiment, the optical lens clamping fixture 100 further includes a movable ring 160 rotatably disposed on the fixing base 110, where the movable ring 160 is used to drive the fin 120 to move toward or away from the center of the mounting hole 110 a.

The optical lens assembly further comprises a locking member 170 in threaded connection with the fixing base 110, wherein the locking member 170 extends along the radial direction of the mounting hole 110a, and the locking member 170 is used for driving the movable ring 160 to rotate in the forward direction or the reverse direction.

It can be understood that, regarding the structure for adjusting the shrink fins 120 and the locking members 170 in this embodiment, which belongs to a technical means commonly used in the art, reference may be made to the patent literature mentioned in the background art, and the innovation point of this embodiment is that the technology is applied to the tooling of the optical lens. In addition, there are many related structures of the fin 120 in the related patent of the adjustable aperture, and it can be understood by referring to the related literature.

Specifically, the movable ring 160 is provided with a chute adapted to the fin 120, and the movable ring 160 rotates forward and backward to lock and expand the fin 120. In addition, other specific structures exist in the optical lens clamping fixture 100, such that the locking member 170 can drive the movable ring 160 to rotate, which is not described herein.

The foregoing disclosure is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
