[0032] The connecting column 1 is a hollow cylindrical structure with two ends, wherein one end located at the lower end is connected to the electric turntable 3 providing power, and the other end located at the upper end is fixedly connected to the base 2.

[0033] The base 2 is a disc-shaped structure, and the base 2 is coaxially connected to the connecting column 1. A protrusion is arranged on the edge of the base 2 which is larger than the diameter of the rotating disk 3, and the pressing block 4 is fixedly connected to the base 2 through the edge protrusion.

[0034] Figure 5 Schematic diagram of a turntable according to an embodiment of the present invention.

[0035] like Figure 5 As shown, the turntable 3 is installed on the base 2, and a through hole is set in the center of the turntable 3. The inner diameter of the through hole in the center of the turntable 3 is larger than the outer diameter of the upper end of the connecting column 1. The turntable 3 is sleeved on the connecting column 1. The turntable 3 is a concentric circle with a diameter smaller than the diameter of the base 2 and the base 2; wherein, a plurality of spirally evenly distributed arc grooves 31 are set on the turntable 3, one end of the arc groove 31 is close to the center of the turntable 3, and the other end is close to the circumferential side of the turntable 3.

[0036] Figure 6 Schematic diagram of a compact according to an embodiment of the present invention.

[0037] like Figure 6 As shown, the pressing block 4 is a plurality of fan-shaped structures, and gaps 41 are reserved between the plurality of fan-shaped structures for accommodating the slider 5 so that the slider 5 can slide radially along the gap 41 .

[0038] There are multiple sliders 5, and the slider 5 has two ends. One end is the upper end, where an optical lens clamping device is set, and the other end is the lower end, which is used to control the spacing between the sliders 5 to adapt to optical lenses of different diameters.

[0039] Figure 7a is a schematic diagram showing a slider according to an embodiment of the present invention; Figure 7b yes Figure 7a Cross-sectional view of .

[0040] like Figure 7a and Figure 7bAs shown, the lower end of the slider 5 has a radial portion 51 and a cylindrical portion 52 from top to bottom, the radial portion 51 is a rectangular parallelepiped structure, and the cylindrical portion 52 is a cylindrical structure, wherein the radial portion 51 is arranged in the gap 41 reserved between the sectors of the pressure block 4, so that the slider 5 can slide and move radially along the gap 41, the slider 5 protrudes from the main body of the slider 5 in a direction perpendicular to the radial direction, and the sector-shaped straight edge of the pressure block 4 is provided with a step to make the gap 41 match with the radial portion 51 of the slider 5; the arc-shaped slot 31 of the turntable 3 has a width smaller than the gap 41 of the pressure block 4, and matches with the cylindrical portion 52 of the slider 5, so that the slider 5 can slide relatively along the arc-shaped slot 31 of the turntable 3.

[0041] When the turntable 3 rotates to change the relative angle with the pressing block 4, the cylindrical portion 52 of the slider 5 is driven to move, so that the slider 5 moves radially along the gap 41 of the pressing block 4, thereby increasing or decreasing the radial distance formed between the multiple pressing blocks 4; when the relative position of the turntable 3 and the base 2 remains unchanged, the slider 5 is fixed in position due to the unchanged relative position of the arc-shaped slot 31 and the gap 41 of the pressing block 4.

[0042] The position where the arc groove 31 and the gap 41 of the pressure block 4 overlap is the position of the slider 5. In this way, the relative position of the slider 5 can be found by rotating the operating turntable 3. It is easy to operate and accurate. The size of the clamped optical lens does not need to be fixed. The clamping device can adapt to optical lenses of various sizes and has strong versatility.

[0043] The flexible clamping device for clamping an optical lens according to the present invention is applied to clamping a circular optical lens during cleaning, and is suitable for flexible clamping of different optical parts within a certain size range, and has the advantages of fast clamping, convenient cleaning, and firm clamping.

[0044] According to one or some embodiments of the present invention, the flexible clamping device for clamping the optical lens also includes: a handle 6, a handle 6 hole 32 is opened on the side of the circumference of the turntable 3 for inserting the handle 6, so as to facilitate the rotation of the turntable 3 to change the distance between the sliders 5, and the protrusion set on the edge of the circumference of the base 2 that is larger than the diameter of the turntable 3 is discontinuous, and a handle 6 groove 21 is reserved for passing the handle 6.

[0045] Figure 4 is a schematic diagram of a base according to an embodiment of the present invention.

[0046] like Figure 4 As shown, a stop screw hole 22 is provided on the raised side of the edge of the base 2 for passing a stop screw to press against the turntable 3, so as to fix the turntable 3 when it is rotated to a suitable position, thereby fixing the relative positions between the sliders 5.

[0047] Figure 2 yes Figure 1 A partial enlarged view of .

[0048] like Figure 2 As shown, the slider 5 is provided with an optical lens clamping device including a chuck 7, a connecting shaft 8, a sleeve 81, a locking screw 83, a spring 82 and a nut. The connecting shaft 8 has two ends. The chuck 7 is connected to one end of the connecting shaft 8 through a thread. A boss is provided on the chuck 7 for placing the lens; the connecting shaft 8 passes through a through hole provided on the upper part of the slider 5, and the connecting shaft 8 is located in the inner section of the through hole on the upper part of the slider 5 and is sleeved with a sleeve 81, a spring 82 and a locking screw 83 for providing elastic force for the chuck 7 to clamp the lens; the other end of the connecting shaft 8 protrudes from the slider 5, and a nut is installed on the protruding part of the connecting shaft 8 for limiting the connecting shaft 8 to prevent the connecting shaft 8 from falling out of the slider 5.

[0049] According to one or some embodiments of the present invention, a fixing hole 23 is provided at a raised position on the edge of the base 2 for fixing the pressing block 4 to the base 2 by screws.

[0050] According to one or some embodiments of the present invention, there are 3-6 pressing blocks 4, and the number of arc-shaped slots 31 on the turntable 3 corresponds one-to-one to the number of pressing blocks 4.

[0051] According to one or some embodiments of the present invention, the number of arc-shaped slots 31 on the pressing block 4 and the rotating disk 3 are both three.

[0052] Figure 3a is a schematic diagram showing a connecting column according to an embodiment of the present invention; Figure 3b yes Figure 3a Cross-sectional view of .

[0053] like Figure 3a and 3b As shown, the connecting column 1 includes multiple cylindrical sections with different radii, and the hollow part is a conical hole 11 near one end of the electric turntable 3 providing power, which is used to be sleeved on the rotating shaft of the electric turntable 3 to achieve a quick and firm connection.

[0054] According to one or some embodiments of the present invention, threads are provided at the top of the connecting column 1 and the center of the base 2 for fixing the connecting column 1 and the base 2 .

[0055] According to one or some embodiments of the present invention, materials at positions that do not affect strength and function in the base 2, turntable 3, and pressing block 4 are removed and hollowed out to reduce the weight of the entire clamping device and save materials.

[0056] When in use, after assembling the tooling of the lens clamping device, insert the handle 6 into the handle 6 hole 32 on the upper side of the turntable 3, and move along the direction of the handle 6 groove 21 of the base 2. At this time, the turntable 3 will rotate accordingly, but a slider 5 is inserted into the groove of the turntable 3, so that it drives the slider 5 to move together. Since the slider 5 is also restricted in radial movement by the pressing block 4, it can only move along the groove direction of the gap 41 between the pressing blocks 4. The three evenly distributed grooves on the turntable 3 can well ensure the synchronization of the three sliders 5 during movement, ensuring that they move forward or backward at the same time.

[0057] When the clamp 7 contacts the lens, if the turntable 3 is rotated continuously, the spring 82 inside the slider 5 will be deformed, and the clamp 7 will be pushed to clamp the lens by the elastic potential energy provided by the spring 82. At the same time, the three clamps 7 clamping the lens can ensure self-centering, which is conducive to clamping the lens.

[0058] The slots on the turntable 3 can realize the self-locking of the structure. After the lens is clamped, the handle 6 is removed and the turntable 3 will not automatically reset. The handle 6 needs to move in the reverse direction to be released.

[0059] The flexible clamping device for clamping an optical lens according to the present invention has a simpler and more reliable structure than the traditional method of using a special clamp for an optical lens, reduces tooling operation and replacement, saves tooling manufacturing costs, has a wider adaptability, and the size of the clampable lens can be set to approximately 25mm-60mm in diameter, which can meet the requirements for cleaning the size of optical lenses of most optoelectronic products.
