[0049] Refer to the attached Figures 1 to 12 A further detailed description is given to an embodiment of a lens frame stud optical knife machine of the present utility model.

[0050] A lens frame stud optical knife machine includes a frame 1. An upper end of the frame 1 is provided with a milling mechanism 2 for milling and flattening the studs of a lens frame 4, and a lower end of the frame 1 is provided with a clamping mechanism 3. The clamping mechanism 3 includes a fixed frame 31, a swing arm 32 and a clamping device 33 for clamping and fixing the lens frame 4, which is rotatably arranged on the swing arm 32 under the drive of a driving motor or a rotary cylinder. The swing arm 32 is swingably arranged on the fixed frame 31, and the swing arm 32 drives the clamping device 33 to swing back and forth under the drive of a driving motor or a rotary cylinder.

[0051] When the optical knife machine mills and flattens the spectacle frame 4, the spectacle frame 4 is first clamped and fixed on the clamping device 33 at the lower end of the frame 1. The milling cutter on the milling mechanism 2 at the upper end of the frame 1 will move downward to mill and flatten the stud at the upper end of the spectacle frame 4. During the processing, the swing arm 32 on the fixing frame 31 drives the clamping device 33 to swing back and forth, so that the stud of the spectacle frame 4 can be evenly milled and flattened by the milling cutter, ensuring its flatness and improving the processing accuracy. After the processing of one end of the spectacle frame 4 is completed, by rotating the clamping device 33, the other end of the spectacle frame 4 is oriented towards the milling mechanism 2, so that the milling mechanism 2 continues to mill and flatten the stud at the other end of the spectacle frame 4, without manual replacement, improving the processing efficiency.

[0052] The milling mechanism 2 includes a mounting plate 21 mounted on the frame 1, a first milling cutter 22, a second milling cutter 23, a first milling cutter driver 24 and a second milling cutter driver 25. The first milling cutter driver 24 and the second milling cutter driver 25 respectively drive the first milling cutter 22 and the second milling cutter 23 to rotate to mill and flatten the spectacle frame 4. The first milling cutter 22 is a rough milling cutter, and the second milling cutter 23 is a fine milling cutter. After the spectacle frame 4 is roughly milled by the first milling cutter 22, it is then finely milled by the second milling cutter 23.

[0053] The mounting plate 21 is provided with a first vertical driver 26 and a second vertical driver 27 that respectively drive the first milling cutter driver 24 and the second milling cutter driver 25 to move vertically. The first vertical driver 26 and the second vertical driver 27 respectively drive the first milling cutter driver 24 to drive the first milling cutter 22 and the second milling cutter driver 25 to drive the second milling cutter 23 to approach or move away from the clamping device 33.

[0054] The upper end of the frame 1 is provided with a first driving assembly 11 that drives the mounting plate 21 to move left and right. The first driving assembly 11 includes a first driver 111 and a first screw 112 connected to the first driver 111. The mounting plate 21 is slidably arranged on the first guide rail 114 of the frame 1 through a first slider 113, and a first connecting block 115 adapted to the first screw 112 is connected to the bottom surface of the mounting plate 21. The first driver 111 drives the milling mechanism 2 to slide left and right on the first guide rail 114 through the first screw 112, moving the first milling cutter 22 or the second milling cutter 23 above the clamping device 33 and directly above the spectacle frame 4, so that both the first milling cutter 22 and the second milling cutter 23 can process the spectacle frame 4.

[0055] The lower end of the frame 1 is provided with a second driving assembly 12 for driving the clamping mechanism 3 to move back and forth. The second driving assembly 12 includes a second driver 121 and a second screw rod 122 connected to the second driver 121. The fixed frame 31 is slidably arranged on the second guide rail 124 of the frame 1 through a second slider 123, and a second connecting block 125 adapted to the second screw rod 122 is connected to one side of the fixed frame 31. The second driver 121 drives the fixed frame 31 to slide back and forth on the second guide rail 124 through the second screw rod 122, so as to adjust the front and rear positions of the temple of the spectacle frame 4 on the clamping device 33, so that the temple of the spectacle frame 4 clamped and fixed on the clamping device 33 can be directly opposite to the milling cutter on the milling mechanism 2, so as to ensure the precise processing of the spectacle frame 4 by the milling cutter and improve the processing accuracy.

[0056] A measurement and induction assembly 28 is arranged on the milling mechanism 2. The measurement and induction assembly 28 includes a measurement cylinder 281, a measurement rod 282 and a measurement inductor 283 fixed to the measurement cylinder 281, which are installed on the second milling cutter driver 25. The measurement rod 282 is movably arranged on the measurement cylinder 281 and is sleeved with a compression spring 284. The measurement rod 282 is arranged directly below the measurement inductor 283.

[0057] Before processing the spectacle frame 4, the first driving assembly 11 is used to drive the mounting plate 21 to drive the milling mechanism 2 to move left and right, so that the measurement rod 282 is placed directly above the spectacle frame 4. Then, the measurement cylinder 281 is used to drive the measurement rod 282 to move downward, so that the lower end of the measurement rod 282 is lower than the height of the second milling cutter 23. Then, the second vertical driver 27 drives the measurement cylinder 281 to move downward, so that the lower end of the measurement rod 282 abuts against the temple of the spectacle frame 4. The second vertical driver 27 continues to drive the measurement cylinder 281 to drive the measurement inductor 283 to move downward, and the measurement rod 282 compresses the compression spring 284 until the upper end of the measurement rod 282 touches the measurement inductor 283, and the measurement inductor 283 completes the stroke measurement action. During this process, the stroke parameters of the second vertical driver 27 are recorded and calculated inside the PLC. This measured value is later compensated into the actual processing data of the first vertical driver 26 and the second vertical driver 27, so as to precisely process the spectacle frame 4. After the measurement is completed, the measurement rod 282 moves upward under the drive of the measurement cylinder 281, so that the lower end of the measurement rod 282 is higher than the height of the milling cutter.

[0058] The clamping device 33 includes a mounting arm 331 and two front clamping assemblies 332 disposed at both ends of the mounting arm 331. The clamping assemblies are used to clamp the two hinged ends 41 of the spectacle frame 4. The front clamping assembly 332 includes an upper clamping member 3321, a lower clamping member 3322, and a front clamping driver 3323. The front clamping driver 3323 drives the lower clamping member 3322 to move towards the upper clamping member 3321, so that the lower clamping member 3322 and the upper clamping member 3321 cooperate to clamp the hinged end 41 of the spectacle frame 4. A rear clamping assembly 333 for clamping the temple 42 is installed at the rear end of the upper clamping member 3321. The rear clamping assembly 333 includes a rear clamping driver 3331, a front clamping arm 3332 fixed to the rear end of the upper clamping member 3321, and a rear clamping arm 3333 connected to the rear clamping driver 3331. The rear clamping driver 3331 drives the rear clamping arm 3333 to move towards the front clamping arm 3332, so that the rear clamping arm 3333 and the front clamping arm 3332 cooperate to clamp the temple 42.

[0059] During use, after the hinged end 41 of the spectacle frame 4 to be processed is pressed against the upper clamping member 3321, the front clamping driver 3323 drives the lower clamping member 3322 to move upwards, so that the lower clamping member 3322 and the upper clamping member 3321 cooperate to clamp the hinged end 41 of the spectacle frame 4. At the same time, the rear clamping assembly 333 at the rear end of the upper clamping member 3321 will clamp and fix the temple 42. Specifically, the rear clamping driver 3331 drives the rear clamping arm 3333 to move towards the front clamping arm 3332, so that the rear clamping arm 3333 and the front clamping arm 3332 cooperate to clamp the temple 42. That is, the front clamping assembly 332 clamps and fixes the hinged end 41 of the spectacle frame 4, and the rear clamping assembly 333 clamps and fixes the temple 42 at the rear end of the spectacle frame 4, completing the firm clamping and fixing of the clamping mechanism 3 to the spectacle frame 4 to be processed. Instead of a worker holding the spectacle frame 4 for processing, it solves the problem that the movement of the spectacle frame 4 caused by the shaking of the worker's hand affects the accuracy of milling and grinding, improves the product processing quality, and can effectively avoid safety problems and ensure the safety of workers.

[0060] A clamping guide rail 33211 is provided at the rear end of the upper clamping member 3321. The upper end of the rear clamping arm 3333 is connected with a clamping slider 33331, and the clamping slider 33331 is slidably disposed on the clamping guide rail 33211. So that the rear clamping arm 3333 moves along the clamping guide rail 33211 with the clamping slider 33331 under the drive of the rear clamping driver 3331, making the rear clamping arm 3333 move more stably back and forth and improving the stability of the product structure.

[0061] In order to enable the clamping mechanism 3 to be applicable to clamping and fixing spectacle frames 4 with different widths, two of the upper clamping members 3321 are movably arranged relative to each other at the left and right ends of the mounting arm 331. An adjusting drive assembly 334 for driving the two upper clamping members 3321 to approach or separate from each other is arranged on the mounting arm 331. The adjusting drive assembly 334 includes an adjusting driver 3341, a transmission gear 3342 connected to the output shaft of the adjusting driver 3341, and two oppositely arranged transmission racks 3343. One end of the transmission rack 3343 is engaged with the transmission gear 3342, and the other end is connected to the corresponding upper clamping member 3321. The adjusting driver 3341 drives the two transmission racks 3343 to move towards or away from each other through the transmission gear 3342, thereby driving the two upper clamping members 3321 to approach or separate from each other, so as to adjust the distance between the two upper clamping members 3321 and enable the clamping mechanism 3 to be applicable to the clamping and fixing of spectacle frames 4 with different widths.

[0062] In order to avoid the situation that the distance between the two upper clamping members 3321 changes by itself, a pressing assembly 335 for pressing and locking the two transmission racks 3343 is arranged above the mounting arm 331. The pressing assembly 335 includes a pressing driver 3351 and two pressing shafts 3352. The upper ends of the two pressing shafts 3352 are connected to the pressing driver 3351, and the lower ends thereof press down on the two ends of the transmission rack 3343. Under the pressure of the pressing driver 3351, the two pressing shafts 3352 firmly press the corresponding transmission racks 3343, preventing the transmission racks 3343 from driving the upper clamping members 3321 to move by themselves. That is, when processing spectacle frames 4 of the same specification, after the distance between the two upper clamping members 3321 is adjusted by the adjusting drive assembly 334, the corresponding transmission racks 3343 are firmly pressed by the pressing shafts 3352 to prevent the distance between the two upper clamping members 3321 from changing during the production and processing of the clamping mechanism 3.

[0063] A vertical guide shaft 33212 is arranged on the upper clamping member 3321 in the vertical direction. A vertical guide hole 33221 adapted to the vertical guide shaft 33212 is provided on the lower clamping member 3322. The lower clamping member 3322 is slidably arranged on the vertical guide shaft 33212 through the vertical guide hole 33221. The lower clamping member 3322 is driven by the front clamping driver 3323 to move smoothly up and down along the vertical guide shaft 33212, avoiding deviation. Thus, the lower clamping member 3322 can better cooperate with the upper clamping member 3321 to clamp and fix the hinged end 41 of the spectacle frame 4.

[0064] Wherein, a horizontal guide shaft 3311 is arranged in the horizontal direction of the mounting arm 331, and the upper clamping member 3321 is provided with a horizontal guide hole 33213 adapted to the horizontal guide shaft 3311. The upper clamping member 3321 is slidably arranged on the horizontal guide shaft 3311 through the horizontal guide hole 33213. That is, when the driving rack 3343 drives the upper clamping member 3321 to move, the upper clamping member 3321 smoothly moves left and right along the horizontal guide shaft 3311, improving the structural stability of the device.

[0065] All the above-mentioned drivers can be power sources such as motors or cylinders. The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
