[0029] The front clamping assembly 2 includes an upper clamping member 21, a lower clamping member 22 and a front clamping driving cylinder 23. The front clamping driving cylinder 23 drives the lower clamping member 22 to move towards the upper clamping member 21, so that the lower clamping member 22 and the upper clamping member 21 cooperate to clamp the hinged end 61 of the eyeglass frame 6;

[0030] A rear clamping assembly 3 for clamping the temple arm 62 is installed at the rear end of the upper clamping member 21. The rear clamping assembly 3 includes a rear clamping driving cylinder 31, a front clamping arm 32 fixed to the rear end of the upper clamping member 21, and a rear clamping arm 33 connected to the telescopic rod of the rear clamping driving cylinder 31;

[0031] The rear clamping driving cylinder 31 drives the rear clamping arm 33 to move towards the front clamping arm 32, so that the rear clamping arm 33 and the front clamping arm 32 cooperate to clamp the temple arm 62;

[0032] During use, after the hinged end 61 of the spectacle frame 6 to be processed is closely attached to the upper clamping member 21, the front clamping drive cylinder 23 drives the lower clamping member 22 to move towards the upper clamping member 21, so that the lower clamping member 22 and the upper clamping member 21 cooperate to clamp the hinged end 61 of the spectacle frame 6; meanwhile, the rear clamping assembly 3 at the rear end of the upper clamping member 21 clamps and fixes the temple 62; specifically, the rear clamping drive cylinder 31 drives the rear clamping arm 33 to move towards the front clamping arm 32, so that the rear clamping arm 33 and the front clamping arm 32 cooperate to clamp the temple 62; that is, the front clamping assembly 2 clamps and fixes the hinged end 61 of the spectacle frame 6, and the rear clamping assembly 3 clamps and fixes the temple 62 at the rear end of the spectacle frame 6; the spectacle frame 6 to be processed is firmly fixed on the clamping mechanism for precise processing; it is used to replace manual holding of the spectacle frame 6 for processing, which well solves the problem that the movement of the spectacle frame 6 caused by the shaking of the worker's hand affects the accuracy of milling; at the same time, it can effectively avoid safety problems and ensure the safety of workers.

[0033] A guide rail 211 is provided at the rear end of the upper clamping member 21, and a slider 331 is connected to the upper end of the rear clamping arm 33. The slider 331 is slidably arranged on the guide rail 211; so that the rear clamping arm 33 moves along the guide rail 211 with the slider 331 under the drive of the rear clamping drive cylinder 31, making the rear clamping arm 33 move more stably back and forth and improving the stability of the product structure.

[0034] A vertical guide shaft 212 is arranged in the vertical direction of the upper clamping member 21, and a vertical guide hole 221 adapted to the vertical guide shaft 212 is provided on the lower clamping member 22. The lower clamping member 22 is slidably arranged on the vertical guide shaft 212 through the vertical guide hole 221; so that the lower clamping member 22 moves smoothly up and down along the vertical guide shaft 212 under the drive of the front clamping drive cylinder 23, avoiding deviation; thus enabling the lower clamping member 22 to better cooperate with the upper clamping member 21 to clamp and fix the hinged end 61 of the spectacle frame 6.

[0035] In order to enable the clamping mechanism to be applicable to clamping and fixing spectacle frames 6 with different widths, two of the upper clamping members 21 are relatively movably arranged at the left and right ends of the mounting base 1, and a driving assembly 4 for driving the two upper clamping members 21 to approach or separate from each other is arranged on the mounting base 1; the driving assembly 4 includes a driving motor 41, a transmission gear 42 connected to the output shaft of the driving motor 41, and two relatively arranged transmission racks 43. One end of the transmission rack 43 is engaged with the transmission gear 42, and the other end is connected to the corresponding upper clamping member 21; when clamping spectacle frames 6 with different widths, the distance between the two upper clamping members 21 needs to be adjusted. The driving motor 41 drives the two transmission racks 43 to move towards or away from each other through the transmission gear 42, so as to drive the two upper clamping members 21 to approach or separate from each other; in order to adjust the distance between the two upper clamping members 21 to be applicable to the clamping and fixing of spectacle frames 6 with different widths.

[0036] In order to avoid the situation that the distance between the two upper clamping members 21 changes by itself, a pressing assembly 5 for pressing and locking the two transmission racks 43 is arranged above the mounting base 1. The pressing assembly 5 includes a pressing cylinder 51 and a pressing shaft 52. The upper end of the pressing shaft 52 is connected to the pressing cylinder 51, and the lower end thereof presses downward on the transmission rack 43; the number of the pressing shafts 52 is two, and the lower ends of the two pressing shafts 52 press downward on the corresponding transmission racks 43 to prevent the transmission racks 43 from moving; under the pressure of the pressing cylinder 51, the two pressing shafts 52 firmly press the corresponding transmission racks 43, avoiding the transmission racks 43 from driving the upper clamping members 21 to move by themselves; that is, when processing spectacle frames 6 of the same specification, after the distance between the two upper clamping members 21 is adjusted by the driving assembly 4, the corresponding transmission racks 43 are firmly pressed by the pressing shafts 52, avoiding the change of the distance between the two upper clamping members 21 during the production and processing of the clamping mechanism.

[0037] A horizontal guiding shaft 11 is arranged in the horizontal direction of the mounting base 1, and the upper clamping member 21 is provided with a horizontal guiding hole 213 adapted to the horizontal guiding shaft 11. The upper clamping member 21 is slidably arranged on the horizontal guiding shaft 11 through the horizontal guiding hole 213; that is, when the transmission rack 43 drives the upper clamping member 21 to move, the upper clamping member 21 smoothly moves left and right along the horizontal guiding shaft 11, improving the structural stability of the equipment.

[0038] 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 in this technical field, 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.
