Working principle: as shown in fig. 1, when the device in the present case works, a user clamps and fixes the lens between the left clamping shaft and the right clamping shaft, and the clamping shaft drives the lens to rotate at a certain rotation speed. In the process of grinding the lens, not only the outer circle of the lens needs to be ground, but also the left side and the right side of the lens need to be chamfered. Therefore, the grinding surface of the grinding wheel is concave with a low middle and high sides. The grinding wheel grinds the excircle by utilizing the inner groove part, and chamfer the lens by utilizing the round tables with two convex sides. This requires that the grinding wheel be fed in both the longitudinal and transverse directions. Therefore, the transverse feeding mechanism and the longitudinal feeding mechanism are matched with each other, and the grinding wheel is driven to contact with the lens, so that the lens is ground.
Further: the grinding wheel need carry out left and right lateral displacement and chamfer the left and right sides face of lens when grinding the excircle, consequently, still be provided with the feed main shaft 11 that driving motor drove on the host computer in this case, install face cam 12 and cylinder cam 13 on the feed main shaft 11, correspondingly: the transverse sliding table 6 is provided with a driving column 15 which is in contact with the end cam 12, and when the end cam 12 rotates, the transverse sliding table 6 is driven to do left-right sliding motion by matching with a reset tension spring or other reset devices. When the transverse sliding table moves left and right, the grinding wheel is driven to move left and right, and the purpose of chamfering left and right or grinding the end face is achieved while the outer circle is ground.
The speed and the stroke of the left-right displacement can be controlled by setting the convex surface and the concave surface of the end cam and the parameters of the inclined surface or the curved surface between the convex surface and the concave surface. For example, when the feeding amount is required to be reduced, the inclined plane between the convex surface and the concave surface of the end face cam can be set to be more inclined so as to slow down the speed of pushing the transverse sliding table to move left and right, reduce the feeding amount and improve the smoothness of the grinding surface, so that the optimal processing state is achieved.
Further: the longitudinal feeding amount of the grinding wheel is carried out by the cooperation between the cylindrical cam and the tappet, the grinding wheel is pushed forward to work by the gravity of the swinging seat and the accessory part on the swinging seat during processing, and the feeding speed of the grinding wheel is realized by the relative extrusion between the cylindrical cam and the tappet.
