[0028] As Figures 2-5 and Figure 8As shown, the clamping assembly 4 includes two rotatable positioning tubes 41, the surface of the positioning tube 41 is fixedly provided with a baffle, the baffle is attached to the inner wall of the bed base 1, the inside of the bed base 1 is provided with a motor (not shown in the figure) for driving the positioning tube 41 to rotate, and a multi-directional translation driving member (not shown in the figure), which can prevent water from entering the inside of the bed base 1 during the movement of the positioning tube 41, the end of the positioning tube 41 is equipped with a suction cup 42 for adsorbing and fixing the optical lens, the inside of the bed base 1 is equipped with a negative pressure system (not shown in the figure), which communicates with the positioning tube 41 and the suction cup 42 and cooperates to adsorb and clamp the optical lens, the surface of each positioning tube 41 is equipped with a model holder 43 that rotates with the optical lens, in this embodiment, two model holders 43 are provided, one on each side of the optical lens, the model holder 43 is shaped like a D-shaped lens after cutting the optical lens, the surface of the model holder 43 is provided with a guide groove 44 along its edge path, the surface of the model holder 43 is uniformly provided with a plurality of rollers 45 for abutting against the edge of the D-shaped lens, in this embodiment, three rollers 45 are provided, equally spaced on the edge of the D-shaped lens, the rollers 45 abut against the edge of the D-shaped lens to form a supporting force that opposes the edging force of the grinding wheel mechanism 2, the surface of the positioning tube 41 is provided with a guide assembly 5 for guiding the movement of the rollers 45, the guide assembly 5 includes a sleeve one 51 rotatably mounted on the surface of the positioning tube 41, a plurality of guide rods 52 are fixedly mounted on the surface of the sleeve one 51, in this embodiment, the guide rods 52 are also provided with three to ensure that the rollers 45 do not rotate synchronously with the model holder 43 during the rotation of the positioning tube 41, while ensuring that the rollers 45 are always attached to the surface of the D-shaped lens, therefore the inside of the bed base 1 is provided with an anti-rotation assembly 8 for preventing the guide rods 52 from rotating with the positioning tube 41, the anti-rotation assembly 8 includes an anti-rotation rod 81 fixedly mounted inside the bed base 1, a sliding groove 82 is provided on the surface of the anti-rotation rod 81, the end of the guide rod 52 is slidingly abutted against the inside of the sliding groove 82, while preventing the guide rod 52 from rotating, the guide rod 52 can also move inside the sliding groove 82.

[0029] It needs to be noted that when in the cutting state, the suction cup 42 and the positioning tube 41 in the clamping assembly 4 clamp and fix the optical lens, the movement and rotation of the positioning tube 41 are controlled by the program, during the movement of the positioning tube 41 with the optical lens, the cutting knife 3 moves on the surface of the optical lens for cutting, thereby obtaining the desired D-shaped lens blank, when in the edging state, the cutting knife 3 needs to be away from the optical lens, then the rollers 45 move to abut against the edge of the D-shaped lens, it is further explained that since the cutting of the optical lens into the D-shaped lens is controlled by the program, therefore during assembly, the path of the guide groove 44 on the surface of the model holder 43 is set to be consistent with the cutting path, at this time, it is not necessary to additionally calibrate the position of the D-shaped lens and the model holder 43, avoiding the error caused by secondary clamping, ensuring the accuracy of edging.

[0030] As shown in Figures 5-7 In order to facilitate the cutting of the optical lens by the cutting knife 3, the surface of the model stand 43 is provided with a mounting assembly 6 for mounting the roller 45. In order to prevent the roller 45 from wearing the edge of the D-shaped lens and affecting the final edging accuracy, the roller 45 needs to be arranged in a rotating manner. The mounting assembly 6 comprises two sealing bearings 61 fixedly arranged at the two ends of the roller 45 respectively. The sealing bearings 61 on the two sides can ensure the stability and smoothness of the rotation of the roller 45, and can also prevent debris from entering the inside of the sealing bearings 61. The surface of the sealing bearing 61 is fixedly sleeved with a mounting cover 63 to further protect the sealing bearing 61. The surface of the mounting cover 63 is fixedly provided with a connecting rod 62. The middle part of the connecting rod 62 has an enlarged diameter section. The guide rod 52 movably penetrates the surface of the enlarged diameter section of the connecting rod 62, so that the connecting rod 62 can only slide along the surface of the guide rod 52. One end of the connecting rod 62 extends into the guide groove 44 and is just fitted on the inner wall of the guide groove 44. The surface of the positioning pipe 41 is provided with a pushing assembly 7 for pushing the roller 45 away from the optical lens to facilitate the cutting of the optical lens by the cutting knife 3.

[0031] In order to facilitate the movement of the two connecting rods 62 in two different directions respectively, one of the sealing bearings 61 is fixedly sleeved at one end of the roller 45, and the other sealing bearing 61 is fixedly provided with a mounting ring 10 with a groove 9 on the inner wall. The end surface of the roller 45 is fixedly connected with a mounting block 11. When the two connecting rods 62 move in different directions, the mounting block 11 will move out of the inside of the groove 9 and away from the D-shaped lens, so as to facilitate the taking out of the D-shaped lens. When the roller 45 needs to abut against the D-shaped lens, the mounting block 11 is located in the inside of the groove 9, so as to ensure the normal rotation of the roller 45.

[0032] The surface of the positioning pipe 41 is slidably provided with a sleeve two 12. In this embodiment, the surface of the sleeve two 12 is equidistantly fixedly provided with three mounting rods 13. One end of the mounting rod 13 is fixedly installed in the inside of the model stand 43. The surface of the positioning pipe 41 is provided with a horizontal groove 14 corresponding to the position of the mounting rod 13. The other end of the mounting rod 13 is slidably installed in the inside of the horizontal groove 14, so as to ensure that the model stand 43 can slide on the surface of the positioning pipe 41 and also can rotate with the positioning pipe 41. The surface of the sleeve two 12 is coaxially fixedly provided with a mounting pipe 15. The mounting pipe 15 is fixedly installed on the surface of the sleeve one 51. The inside of the mounting pipe 15 is fixedly provided with a bearing one 16. The bearing one 16 is fixedly sleeved on the surface of the sleeve two 12. The bearing one 16 can not only prevent the guide rod 52 from rotating with the positioning pipe 41, but also can ensure that the guide rod 52 drives the connecting rod 62 to move away from the D-shaped lens together with the model stand 43.

[0033] The pushing assembly 7 comprises bearing No.2 71 fixedly sleeved on the surface of the sleeve No.2 12, the bearing No.1 16 and the bearing No.2 71 are respectively located at both sides of the mounting rod 13, the surface of the positioning pipe 41 is slidingly sleeved with a sleeve cover 72, the bearing No.2 71 is fixedly installed in the inside of the sleeve cover 72, the surface of the sleeve cover 72 is fixedly installed with a moving rod 73, one end of the moving rod 73 extends into the inside of the lathe bed base 1, and an electric push rod (not shown in the figure) is installed in the inside of the lathe bed base 1, the electric push rod can be fixed on the surface of the baffle, and the electric push rod drives the moving rod 73 to move, so that the movement of the model frame 43 is realized.

[0034] It should be noted that, since the bearing No.1 16 and the bearing No.2 71 need to bear the pulling force when the moving rod 73 is pulled, the bearing No.1 16 and the bearing No.2 71 need to be able to bear the axial load, so the bearing No.1 16 and the bearing No.2 71 can be selected from angular contact bearings or deep groove ball bearings.

[0035] The cutting mode of the optical lens is first needed, at this time, the roller 45 needs to be away from the optical lens, the electric push rod drives the moving rod 73 to pull the sleeve cover 72 to move along the axial direction of the positioning pipe 41, through the action of the bearing No.1 16, the bearing No.2 71, the guide rod 52 and the connecting rod 62, the roller 45 is pulled away from the optical lens, the positioning pipe 41 is clamped on the surface of the optical lens, the cutting knife 3 moves and abuts against the surface of the optical lens, then the positioning pipe 41 clamps and rotates the optical lens, the cutting knife 3 moves on the surface of the optical lens, so that the optical lens is cut to obtain a D-shaped lens; then the centering and edging mode of the D-shaped lens is needed, the electric push rod drives the moving rod 73 to push the sleeve cover 72 to move again, so that the mounting block 11 is clamped into the inside of the groove 9, at this time, the positioning pipe 41 drives the model frame 43 to rotate, and the D-shaped lens also rotates, since the roller 45 also rotates, the abrasion of the optical lens caused by the rotation of the roller 45 can be effectively avoided, the grinding wheel mechanism 2 rotates at high speed and approaches the surface of the D-shaped lens, at this time, a large edging force is generated, however, the three rollers 45 in different directions abut against the surface of the D-shaped lens at the same time, a supporting force resisting the edging force is formed, so as to ensure the accuracy of the edging; the cutting mode and the edging operation mode are converted and matched through a shared device, so that the cutting operation and the centering and edging operation of the D-shaped lens are finally realized.

[0036] It needs to be explained that although the roller 45 and the corresponding connecting structure are additionally added in the technical scheme of the present application, they are all common mechanical structures in the field, and there is no high-cost precision part, so the cost of adding the above structure is low, and only the corresponding structure needs to be installed when the edge is ground for the first time, and the subsequent centering and edge grinding can be continuously used, and the accuracy of the centering and edge grinding can be effectively improved, so the cost of the above structure added is basically negligible, and the above technical scheme of the present application is a specific improvement based on the above prior art and solving the technical problem.
