Technical Field
The invention relates to the technical field of optical glass processing equipment, in particular to a swing rod device for an optical grinding and polishing machine.
Background
When an optical lens is processed, a polishing machine is generally adopted for processing, and the polishing machine in the prior art mainly comprises a main shaft, a main shaft motor connected with the main shaft and used for driving the main shaft to rotate, and a ball mill arranged on the main shaft; a swing frame is further arranged on the body of the polishing machine, a swing rod is fixedly arranged on the swing frame, and a stylus is arranged at the end part of the swing rod; the stylus on the swing rod is tightly pressed on the upper die through the arranged cylinder, so that the optical lens mounted on the die is ground on the ball mill; and the swing amplitude of the stylus on the swing frame is adjusted through the arranged cam mechanism.
However, the swing motion of the existing optical grinding and polishing machine varies with the lens R, and when the lens is at different positions on the ball mill, the stress of the lens is different under the same pressure condition, as shown in the attached
The main reason is that the stress of the lens at the center position and the edge position of the ball mill is different, when the lens is at the center position of the ball mill, the stylus is perpendicular to the tangent line of the ball mill, but when the lens is at the left edge position and the right edge position of the ball mill, the stylus is still vertical downwards, at the moment, the stress of the lens will change in time, and the stress of the lens is uneven in the grinding process.
Disclosure of Invention
The invention aims to overcome the defect that the stress of the optical grinding and polishing machine lens is not uniform in the ball milling center and the edge position when the optical grinding and polishing machine lens is processed in the prior art, and provides the swing rod device for the optical grinding and polishing machine.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a swing rod device for an optical grinding and polishing machine comprises a swing frame, a swing rod and a stylus, wherein the swing frame is arranged on a rack of the grinding and polishing machine, the swing frame is connected with a cam mechanism used for driving the swing frame to swing back and forth, and the cam mechanism is connected with a driving motor used for driving the cam mechanism to rotate;
the swing frame is fixedly provided with a swing rod outer sleeve, the swing rod is rotatably arranged in the swing rod outer sleeve, one end of the swing rod is fixedly arranged with the iron pen after extending out of the swing rod outer sleeve, and the other end of the swing rod is connected with a driving assembly which is used for driving the swing rod to rotate in the swing rod outer sleeve;
the driving assembly comprises an execution cylinder I and an execution cylinder II, one end of the execution cylinder I and one end of the execution cylinder II are connected with the swing frame, the other end of the execution cylinder I and one end of the execution cylinder II are connected with the swing rod, the rotation amount of the swing rod is controlled by controlling the extension and the shortening of the execution cylinder I and the execution cylinder II, and the extension amount/the shortening amount of the execution cylinder I is the same as the shortening amount/the extension amount of the execution cylinder II.
Wherein, the swing rod is fixedly arranged in the swing rod outer sleeve through a bearing.
Further limiting, the execution cylinder I and the execution cylinder II are connected with the swing frame and the swing rod in a hinged mode.
