Eyeglass lens processing apparatus

摘要

An eyeglass lens processing apparatus includes: a lens rotation unit configured to rotate a lens chuck shaft; a processing tool rotational shaft to which a processing tool is attached; a shaft-to-shaft distance change unit that includes a carriage which holds the lens chuck shaft or the processing tool rotational shaft and is movable in a direction where a shaft-to-shaft distance between the lens chuck shaft and the processing tool rotational shaft changes by driving a motor, a movement member that is moved in the shaft-to-shaft distance direction, a connection member that connects the movement member and the carriage, and a deformation detecting sensor configured to detect a deformation of the connection member; and a controller configured to control the driving of the motor based on a detection result of the deformation detecting sensor.

1. An eyeglass lens processing apparatus comprising:
a lens chuck shaft configured to hold an eyeglass lens; a lens rotation unit configured to rotate the lens chuck shaft; a processing tool rotational shaft to which a processing tool for processing a periphery of the lens is attached; a shaft-to-shaft distance change unit that includes:
a motor;a carriage which holds one of the lens chuck shaft and the processing tool rotational shaft and is movable in a direction where a shaft-to-shaft distance between the lens chuck shaft and the processing tool rotational shaft changes by driving the motor;a movement member that is moved in the shaft-to-shaft distance direction by driving the motor;a connection member that connects the movement member and the carriage; anda deformation detecting sensor that is provided in the connection member and is configured to detect a deformation of the connection member in the shaft-to-shaft distance direction; and a controller configured to control the lens rotation unit and the shaft-to-shaft distance change unit to process the periphery of the lens using the processing tool based on an input target lens shape, the controller controlling the driving of the motor based on a detection result of the deformation detecting sensor.
