Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to a clamping device for optical lens processing. Background Art

[0002] Optical lenses usually need to be fixed using a clamping device during the processing.

[0003] The prior art discloses a clamping structure for processing optical lenses that prevents them from falling off, such as the one disclosed in Chinese patent CN116749097A. Although this structure makes it easy for users to install the device, improves the humanized design of the device, and is conducive to its widespread promotion and use in society, when using the device, the user is required to twist multiple sets of rotating screws in sequence so that the circular protective pads at one end of the multiple sets of rotating screws are clamped around the optical lens. When the optical lens is placed inside the structure, it is impossible to control several sets of circular protective pads to move toward the direction of the optical lens at the same time, which makes the operation process inconvenient, and it is also difficult to ensure that the optical lens is clamped at the center of the structure, which makes it inconvenient to process the optical lens after it is clamped. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a clamping device for optical lens processing.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0006] A clamping device for processing an optical lens, comprising a support, an annular cover connected to the support, a plurality of through holes opened on the side wall of the annular cover, guide rods slidably arranged inside the plurality of through holes, a plurality of connecting blocks connected to the ends of the guide rods arranged inside the annular cover, a positioning clamping plate connected to the connecting blocks, and a rotating ring rotatably connected to one side of the annular cover;

[0007] Wherein, a synchronous driving component acting on the connecting blocks is arranged between the rotating ring and a plurality of groups of the connecting blocks.

[0008] As a further solution of the utility model: the synchronous drive assembly includes a plurality of screw rods fixedly connected to the plurality of connecting blocks, and a plurality of screw sleeves threadedly sleeved on the screw rods and rotatably connected to the annular cover;

[0009] Wherein, a rotating component acting on the screw sleeve is arranged between the rotating ring and the plurality of groups of screw sleeves.

[0010] As a further solution of the utility model: the rotating assembly includes a plurality of rotating shafts rotatably connected to the support, a circular gear sleeved on one end of the rotating shaft, and a gear ring disposed on the surface of the rotating ring and meshing with the circular gear;

[0011] Wherein, a transmission assembly is arranged between the rotating shaft and the screw sleeve.

[0012] As a further solution of the utility model: the transmission assembly includes a first bevel gear sleeved on the surface of the screw sleeve, and a second bevel gear sleeved on one end of the rotating shaft and meshing with the first bevel gear.

[0013] As a further solution of the utility model: a circular handle is connected to the outer side of the rotating ring.

[0014] As a further solution of the utility model: a rubber contact piece is arranged on the surface of the positioning clamping plate.

[0015] After adopting the above structure, the utility model has the following advantages compared with the prior art: by extending the optical lens to be clamped into the interior of the annular cover, it is only necessary to rotate the rotating ring on the annular cover to control several groups of connecting blocks inside the annular cover to move toward the inner side of the annular cover at the same time; when the positioning clamps on several groups of connecting blocks all conflict with the side walls of the optical lens extending into the annular cover, several groups of positioning clamps can clamp the optical lens from around it; at this time, under the clamping action of several groups of positioning clamps, the optical lens is positioned in the middle position of the annular cover, which makes it easier for people to process it; and since it is only necessary to control the rotation of the rotating ring to simultaneously control the movement of several groups of positioning clamps, the operation process is also more convenient.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a clamping device for processing an optical lens includes a support 1, an annular cover 2 is connected to the support 1, a plurality of through holes 3 are opened on the side wall of the annular cover 2, guide rods 4 are slidably arranged inside the plurality of through holes 3, a plurality of connecting blocks 5 connected to the ends of the guide rods 4 are arranged inside the annular cover 2, a positioning clamp 6 is installed on the connecting blocks 5, and a rotating ring 7 is rotatably connected to one side of the annular cover 2;

[0023] Wherein, a synchronous driving assembly acting on the connecting blocks 5 is arranged between the rotating ring 7 and a plurality of groups of the connecting blocks 5;

[0024] Since the guide rod 4 is slidably arranged inside the through hole 3, when the connecting block 5 inside the annular cover 2 is driven to move, the connecting block 5 will maintain a straight line slide toward the inside or outside of the annular cover 2 without deflection under the guidance of the through hole 3 and the guide rod 4. By rotating the rotating ring 7 on the annular cover 2, the synchronous driving component will simultaneously generate a driving effect on several groups of connecting blocks 5 to move toward the inside or outside of the annular cover 2. Under this driving effect, several groups of connecting blocks 5 will synchronously slide straight lines toward the inside or outside of the annular cover 2, and the optical lens to be positioned is placed on the connecting block 5 inside the annular cover 2. By rotating the rotating ring 7, several groups of connecting blocks 5 inside the annular cover 2 are controlled to move toward the inner side of the annular cover 2 at the same time. When the positioning clamps 6 on the several groups of connecting blocks 5 all conflict with the side walls of the optical lens extending into the annular cover 2, the several groups of positioning clamps 6 can clamp the optical lens from the periphery at the same time. At this time, under the clamping action of the several groups of positioning clamps 6, the optical lens can be kept in the middle position of the annular cover 2, which is convenient for people to process the optical lens, and the several groups of positioning clamps 6 can be controlled to move at the same time only by controlling the rotating ring 7 to rotate, and the operation process is more convenient.

[0025] In one embodiment of the utility model, the synchronous drive assembly includes a plurality of screw rods 8 fixedly connected to the connecting blocks 5, and a plurality of screw sleeves 9 threadedly sleeved on the screw rods 8 and rotatably connected to the annular cover 2;

[0026] Wherein, a rotating assembly acting on the screw sleeve 9 is arranged between the rotating ring 7 and the plurality of groups of screw sleeves 9;

[0027] When the rotating ring 7 is rotated, several groups of screw sleeves 9 will rotate simultaneously under the driving action of the rotating component. Due to the thread matching relationship between the screw sleeve 9 and the screw rod 8, several groups of screw sleeves 9 will simultaneously drive the screw rod 8 to move along the inside of the screw sleeve 9, thereby causing several groups of connecting blocks 5 to be driven to move toward the inside or outside of the annular cover 2 at the same time under the driving action of the screw rod 8.

[0028] In another embodiment of the utility model, the rotating assembly includes a plurality of rotating shafts 10 rotatably connected to the support 1, a circular gear 11 sleeved on one end of the rotating shaft 10, and a gear ring 12 disposed on the surface of the rotating ring 7 and meshing with the circular gear 11;

[0029] Wherein, a transmission assembly is provided between the rotating shaft 10 and the screw sleeve 9;

[0030] When the rotating ring 7 is rotated, the rotating ring 7 will drive the gear ring 12 on its surface to rotate. Due to the meshing relationship between the gear ring 12 and the circular gear 11, the circular gear 11 sleeved on one end of the rotating shaft 10 will rotate under the driving action of the gear ring 12, thereby making several groups of rotating shafts 10 rotate synchronously at the same time under the drive of the circular gear 11. When the rotating shaft 10 is in the process of synchronous rotation, it will drive several groups of screw sleeves 9 to rotate synchronously through the transmission assembly.

[0031] In another embodiment of the present utility model, the transmission assembly includes a first bevel gear 13 sleeved on the surface of the screw sleeve 9, and a second bevel gear 14 sleeved on one end of the rotating shaft 10 and meshing with the first bevel gear 13;

[0032] The rotating shaft 10 can drive the second bevel gear 14 at one end thereof to rotate during the rotation process, and the second bevel gear 14 can drive the first bevel gear 13 meshing therewith to rotate, thereby causing the screw sleeve 9 to rotate under the driving action of the first bevel gear 13 .

[0033] In another embodiment of the present utility model, a circular handle 15 is connected to the outer side of the rotating ring 7;

[0034] When the rotating ring 7 is rotated, the circular handle 15 connected to the rotating ring 7 is convenient for people to grasp, thereby making it convenient for people to control the rotation of the rotating ring 7.

[0035] In another embodiment of the present utility model, a rubber contact sheet 16 is provided on the surface of the positioning clamp plate 6;

[0036] When the positioning clamp 6 contacts and clamps the surface of the optical lens, the rubber contact piece 16 will directly contact the surface of the lens. Since the material of 16 is relatively soft, the side wall of the optical lens can be prevented from being damaged under the clamping action.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
