Description

Technical Field

[0001] The utility model relates to the field of grinding, in particular to a rough grinding machine for lens processing. Background Art

[0002] Optical lens is an optical element used to adjust light and change the light path. It is used in various visual systems, such as telescopes, electron microscopes, photographic lenses, laser equipment, etc. Among them, optical lenses that have been polished can greatly improve their optical performance and imaging effects. Grinding and polishing refers to placing the optical lens in a specific grinder and grinding its surface with sandpaper and abrasives of different particle sizes to remove surface unevenness, burrs and tiny defects, and make its surface smoother.

[0003] After searching, Chinese patent announcement number: CN217596692U discloses an edge and corner grinder for processing optical sight lenses. The grinding disc and the connecting sleeve are connected by a connecting column. By rotating the clamping piece, the built-in torsion spring is elastically deformed, so that one end of the clamping piece is separated from the clamping groove opened by the connecting column, thereby facilitating the connection column to be pulled out from the inside of the connecting sleeve and facilitating the removal and replacement of the grinding disc.

[0004] In the above technical solution, the grinding disc can be removed and replaced by utilizing a clamping fixture in conjunction with a torsion spring. However, when the grinding disc is used to grind the lens, the dust and smoke generated cannot be collected and cleaned. The dust and smoke will adhere to the surface of the grinder and affect its mechanical parts, which is not conducive to cleaning and may harm the health of personnel. At the same time, it will have an adverse effect on the polished lens. Therefore, a rough grinder for lens processing is proposed to solve the above problems. Utility Model Content

When the motor 15 stops running, the elastic force of the spiral spring 20 will drive the support rod 18 to rotate and reset, so that the arc plate 19 is reversed to stir the water source, thereby improving the effect of removing impurities, and starting the motor 24. The motor 24 reciprocates to drive the driving wheel 25 to rotate, and the transmission belt is used to make the driven wheel 26 drive the suction pipe 6 to rotate on the ring 23, and then the dust cover 5 is swung back and forth to expand the dust and smoke absorption area. Finally, the knob 22 is turned to make the threaded rod 21 drive the filter plate 12 to rise, so that the filter plate 12 can be removed from the receiving shell 11 to clean the impurities, thereby improving the cleanliness of the lens during polishing.
