Problems solved by technology

During the grinding and polishing of optical components, the small tool is pressed down (that is, the amount of pressure is increased), the movement axis is connected to the small tool ball head, so that the small tool always touches the surface of the optical component and the axis of the small tool is always perpendicular to the surface of the optical component; small During the tool lifting process (i.e., reducing the amount of pressing), the movement axis is separated from the small tool, and the effective load transfer is lacking, resulting in a change in the removal function of the small tool, resulting in an unstable amount of material removal; at the same time, the small tool axis and the surface of the optical element are no longer Vertical, prone to large IF ripple errors

Embodiment

[0048] 1) The drive motor 1 is located at the top, and the grinding and polishing tool 7 is located at the bottom, and the bracket 2 of the grinding and polishing device is fixedly installed on the sixth axis flange end of the industrial robot 9 through the installation hole. The center line angle a of the input end sleeve fork 61 and the output end sleeve fork 63 is adjusted to be 0° (the deviation of the center line angle ≤ 1 ') by the limit sleeve 8. Adjust the sleeve fork 63 at the output end so that the lower surface of the grinding and polishing tool 7 is parallel to the reference plane 11-1 of the turntable (included angle≤10").

[0049] 2) The working turntable 10 is located in front of the robot 9 , and the optical element 11 to be processed is fixed on the working turntable 10 . It is stipulated that facing the industrial robot 9, the center point of the working turntable 10 is the origin, and the connection line between the industrial robot 9 and the working turntab...
