Precision automatic dripping device for polishing liquid for small grinding head polishing machine

Abstract

A precision automatic dripping device for polishing liquid specially used for small grinding head polishing machines, including a computer, a peristaltic pump, and a container placed on a magnetic stirrer, the container is filled with polishing liquid; one end of the hose of the peristaltic pump is placed in the container, and the other One end is fixed on the polishing head of the small grinding head polishing machine, and the computer is connected with the peristaltic pump to control the rotor speed n of the peristaltic pump, and the rotor speed n satisfies the following conditions: n=k*h* V / (L+V). The invention can precisely and automatically control the dripping of the polishing liquid to the surface to be polished, the polishing liquid is evenly added, saves manpower, the shape converges quickly after processing, and the removal is uniform, and has the advantages of simple control and precise dripping.

Description

technical field [0001] The invention belongs to the field of optical processing, and relates to a small grinding head polishing machine for polishing optical elements, in particular to a precise automatic dripping device for polishing liquid used in the process of modifying the surface of the optical element. Background technique [0002] Small grinding head polishing machine is a kind of CNC polishing equipment widely used in optical polishing. In the process of polishing optical components with small grinding head polishing machine, because the size of the small grinding head is relatively small relative to the workpiece, it can fit the spherical surface well , the curvature change of each point of the plane and aspherical surface shape, so that the grinding head can always maintain a good fit with the surface shape of the polished surface, so as to obtain high processing accuracy; on the other hand, due to the use of computer-controlled polishing disc for Processing, comp...

Problems solved by technology

The disadvantage of this dripping method is that it depends on the experience of the workers. Different workers drop different amounts of polishing liquid, and for components with a radius of curvature, the polishing liquid that is first dropped at a certain point will spread more to the surroundings. The lower side flows away, resulting in no polishing solution on the surface when the polishing head moves to this point. The most important thing is that the speed of manual dripping cannot match the moving speed of the small grinding head, and the drop volume will be uneven.

The difference in the amount of surface polishing liquid will make the stability of the removal function worse, affect the removal efficiency and accuracy, and increase the cost
