Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology, it is difficult to remove the lens from the fixing device when the existing lens edging machine is processing the lens. Forcibly removing the lens will easily affect the surface quality of the lens and even cause the lens to be scrapped. A semi-rocker lens edging machine proposed by the present invention

Embodiment approach
[0029] As an embodiment of the present invention, sliding grooves 251 are evenly provided on the part of the pressing disk 25 close to the inner surface of the fixed disk 21, each of the sliding grooves 251 is embedded with a No. 1 rod 252, so The No. 1 rod 252 is connected to the inner surface of the chute 251 through an elastic rope 253, the end of the No. 1 rod 252 stretches out from the chute 251, and the No. 1 rod 252 is an elastic rod; the No. 1 rod is pushed by gas The upward movement of 252 acts on the end of the fixed disc 21, making the removal of the lens more convenient; during work, when the flowing air flows out from the gap between the pressure rod 242 and the No. 1 channel 222, the flowing air is pressed by the pressing disc 25 The barrier function of the surface makes the flow air flow along the surface of the pressure disc 25, and the pressure disc 25 is further squeezed by the impact of the flow air to squeeze the lens; the air flowing along the surface of th...

The invention relates to the technical field of edge grinding machines, in particular to a half rocker arm lens edge grinding machine which comprises an edge grinding unit and a fixing unit. The edge grinding unit comprises a machine body, a machine cover, a working groove, an operation screen, a control center, a grinding wheel and a cooling water pipe, wherein the working groove is formed in the upper surface of the machine body. A fixing disc is arranged at the end of a fixing shaft, the fixing disc makes close contact with the surface of a lens, air in the area between the fixing disc and the lens flows out through a first channel, and therefore the lens is subjected to the negative pressure effect and is tightly fixed; and in addition, when the lens is taken down, air in the area between the fixed disc and the lens is supplemented through an air tank, so that the negative pressure action on the lens is relieved, and the lens can be taken down smoothly.
Description
technical field [0001] The invention relates to the technical field of edging machines, in particular to a semi-rocker lens edging machine. Background technique [0002] Ophthalmic lenses for eyeglasses can be made from many different materials such as glass, plastic, polycarbonate and thermoplastic resins. Ophthalmic lenses undergo a series of molding, resurfacing, and polishing operations that determine the geometry of both the convex and concave optical surfaces of the lens. This surface modification can be followed by appropriate surface treatments such as multi-coating, hard-coating or coloring. The final step in ophthalmic lens manufacture is edging, which involves machining the edge or perimeter of the lens to conform the size and shape of the lens to the size and shape of the frame in which the lens is to be installed. [0003] However, when the existing lens edging machine is processing the lens, the lens needs to be fixed at first; and it is difficult to control ...
