Edge grinding device for large-size video monitoring camera lens

The utility model discloses a large-size video monitoring camera lens edge grinding device which is characterized by comprising a base (1), a controller (5), a mounting frame (2), a rotatable lens clamping mechanism, a motor (3), an advancing mechanism, an elastic device and a grinding head (11) which is arranged on the elastic device and is provided with an arc-shaped concave surface. By means of the grinding head with the arc-shaped concave face, the lens edge of the lens can be well wrapped, the position of the grinding head does not need to be adjusted during edge grinding, surrounding attaching type grinding of the large-size camera lens can be achieved, meanwhile, the grinding head with the arc-shaped concave face can effectively ensure the smoothness of the ground edge, and the grinding quality of the large-size camera lens is improved. Therefore, the problems of low edge grinding efficiency and poor edge grinding effect due to the fact that the direction of the edge grinding body needs to be changed o
