Abstract
Description
Technical Field
[0001] The utility model relates to the field of lens processing, in particular to a lens polishing machine. Background Art
[0002] In a lens polishing machine, the lens to be polished is usually fixed on a polishing disc, and the polishing disc is driven by a motor to rotate at a certain speed. At the same time, polishing liquid will flow between the polishing disc and the lens to help remove impurities and scratches on the lens surface.
[0003] The use of a lens polishing machine can greatly improve the efficiency and precision of lens polishing, and also improve the smoothness and transparency of the lens.
[0004] At present, traditional polishing machines directly fix the lens on the polishing disc for polishing. However, due to different surface conditions of the lens, the polishing disc rotates in only one direction for polishing, resulting in a single polishing position on the polishing surface. Content of the Utility Model
[0005] The utility model provides a lens polishing machine, whose main purpose is to overcome the defect that when the lens is fixed on the polishing disc for polishing, the polishing position on the polishing surface is single.
[0006] To solve the above technical problems, the utility model adopts the following technical solutions:
[0007] The present disclosure provides a lens polishing machine, including a grinding pool, at least one polishing disc disposed in the grinding pool, at least one grinding disc, at least one link mechanism, at least one first power mechanism, and at least one second power mechanism. The bottom of the grinding disc is used for mounting the lens. The second power mechanism is used to drive the polishing disc to rotate. The grinding discs are all adaptively disposed on the polishing disc. The first power mechanism is used to drive the corresponding link mechanism to reciprocate. A grinding disc is disposed at the front end of each link mechanism. When the link mechanism drives the grinding disc to reciprocate, the grinding disc drives the lens to move between a first position and a second position, so that the lens and the grinding disc rub against each other.
[0008] In a possible implementation, at least one machine base is provided on the rear part of the grinding pool. The link mechanism includes at least one first pivot seat provided on the machine base, at least one cam provided on the rear side of the first pivot seat, at least one first pivot portion provided on the cam, at least one first extension portion extending in the direction of the cam on the first pivot seat, at least one second extension portion extending in the direction of the polishing disc on the first pivot seat, and at least one first link. The rear part of the first link is mounted on the first pivot portion, the front part of the first link is mounted on the first extension portion, and the output shaft of the first power mechanism is mounted on the cam to drive the cam to rotate. The cam drives the first extension portion and the second extension portion to swing around the first pivot seat through the first link.
[0009] In a possible implementation, the first extension portion, the second extension portion, and the first pivot seat are integrally formed.
[0010] In a possible implementation, the first power mechanism includes at least one first motor provided in the machine base, and each first motor correspondingly drives a corresponding cam to rotate.
[0011] In a possible implementation, the second power mechanism includes at least one second motor provided on the bottom of the grinding pool, and each second motor correspondingly drives a corresponding polishing disc to rotate.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] The structure of the present utility model is simple and practical. By setting a link mechanism to drive the grinding disc to reciprocate, the grinding disc drives the lens to move between a first position and a second position, so that the polishing position of the lens is changed, thereby increasing the polishing position of the polishing disc on the lens and making the polishing surface more uniform, improving the polishing effect.
