本发明为在研磨和抛光机上加工光学透镜时的一种固紧装置。众所周知,在研磨和抛光凸面或凹面透镜时,一般都采用一种模盘。这种模盘在研磨盘内运动,被加工的透镜就位于这两者之间。在加工许多同一形状的透镜时,可将许多透镜固定在一个夹持工件的模盘上,模盘和研磨盘具有与成品透镜相同的曲率。但在采用这种类型的装置时,光学透镜要用沥清或类似的材料粘贴到模盘上去,进行这样的粘贴是非常费时间的,同时也是困难复杂的,因为要达到使工件
The present invention is a fastening device for processing optical lenses on a grinding and polishing machine. As we all know, in the grinding and polishing of convex or concave lens, the general use of a mold plate. The mold plate moves in the grinding disc and the lens being processed is located between the two. In processing many lenses of the same shape, a number of lenses can be attached to a mold plate that holds the workpiece with the same curvature as the finished lens. However, when using this type of device, the optical lens is pasted with a bitumen or the like onto the mold plate. Such a paste is very time-consuming and also difficult and complex to achieve,
