DETAILED DESCRIPTION

[0017] 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.

[0018] In order to facilitate the chamfering of lenses of different thicknesses, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a base 1, a rotating mechanism, a clamping mechanism, a pressing assembly and a chamfering assembly. The lens to be chamfered is centrally arranged on the upper surface of the base 1, the rotating mechanism is arranged at the lower part of the base 1, and the pressing assembly is arranged vertically above the base 1 through a support plate 2. As the rotating mechanism drives the base 1 to rotate, the lens on the upper surface of the base 1 rotates about the center of a circle on the base 1 through the cooperation of the clamping mechanism and the pressing assembly. The chamfering assembly is used to chamfer the lens during the rotation process. The four limit columns 9 are driven by the clamping cylinder 6 to form a positioning area, so that the lens will not deviate during the rotation process in the base 1, affecting the accuracy of the chamfering. The pressing block is driven by the first telescopic cylinder 10 to press the lens, which can further improve the stability of the lens during rotation. Under the adjustment of the second telescopic cylinder 12 and the third telescopic cylinder 15, the height of the upper chamfering drill bit 14 and the lower chamfering drill bit 17 can be changed according to the thickness of the lens and the required chamfering thickness, thereby improving adaptability and being able to chamfer lenses of different thicknesses.

[0019] In order to improve the accuracy of the lens chamfering process, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base 1 is cylindrical and is arranged on a workbench 3. The rotating mechanism includes a motor 4 arranged vertically below the base 1. The motor 4 drives the base 1 to rotate, driving the lens to be chamfered to rotate accordingly, so as to facilitate the chamfering of the lens later. The power output end of the motor 4 is connected to a rotating shaft 5, which is connected to the base 1, so as to drive the base 1 to rotate. The clamping mechanism also includes a clamping cylinder 6 arranged on one side outside the base 1, and clamping plates 7 are respectively arranged on the power output ends on both sides of the clamping cylinder 6. The two clamping plates 7 have protrusions 8 extending toward one side of the base 1, and two limiting columns 9 are arranged on the protrusions 8. The two clamping plates 7 are driven by the clamping cylinder 6 to move toward the base 1, driving the movement of the protrusions 8, so that the four limiting columns 9 limit the lens placed on the upper surface of the base 1, so as to make the center of the lens and the center of the base 1 on the same vertical line, thereby improving the lens from deviating during the rotation process in the later stage and improving the accuracy of its chamfering. When the lens is rotated, the limiting column 9 does not contact the lens to avoid affecting the rotation of the lens.

[0020] Furthermore, there are four limit posts 9, and a positioning area for placing the lens is formed between the four limit posts 9. The positioning area is used to locate the rotation center of the lens in the later stage to avoid deviation. The support plate 2 is arranged on the workbench 3, and the pressing assembly includes a first telescopic cylinder 10 arranged on the support plate 2, and the power output end of the telescopic cylinder is connected to a pressing plate 11. The pressing plate 11 and the power output end of the first telescopic cylinder 10 are rotatably connected, so that the pressing plate 11 can rotate. In this way, when the pressing plate 11 abuts against the lens, the pressing plate 11 can rotate with the rotation of the lens, and the rotation speed of the lens will not be affected while ensuring that the lens does not deviate. The chamfering assembly includes an upper chamfering unit and a lower chamfering unit. The upper chamfering unit includes a second telescopic cylinder 12 arranged on the workbench 3 and located on the other side of the base 1. The power output end of the second telescopic cylinder 12 is connected to an upper chamfering motor 13, and the upper chamfering motor 13 is connected to an upper chamfering drill 14. The lower chamfering unit includes a third telescopic cylinder 15 which is arranged on the workbench 3 and adjacent to the second telescopic cylinder 12. The power output end of the third telescopic cylinder 15 is connected to a lower chamfering motor 16, and the lower chamfering motor 16 is connected to a lower chamfering drill bit 17. The heights of the upper chamfering drill bit 14 and the lower chamfering drill bit 17 are adjusted by the second telescopic cylinder 12 and the third telescopic cylinder 15, so that lenses of different thicknesses can be chamfered, and the height of the upper chamfering drill bit 14 is lower than that of the lower chamfering drill bit 17.

[0021] When in use, firstly, the four limit columns 9 are driven by the clamping cylinder 6 to form a positioning area, so that the lens will not deviate during the rotation process in the base 1, and the first telescopic cylinder 10 drives the pressing block to press the lens, which can further improve the stability of the lens during rotation. Under the adjustment of the second telescopic cylinder 12 and the third telescopic cylinder 15, the height of the upper chamfering drill bit 14 and the lower chamfering drill bit 17 can be changed according to the thickness of the lens and the required chamfer thickness, so that lenses of different thicknesses can be chamfered.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
