Description

Technical Field

[0001] The utility model relates to the technical field of optical glass processing, in particular to a grinding disc specially used for optical glass lenses. Background Technique

[0002] Optical glass is a kind of glass used in the optical field, which has the ability to change the propagation direction of light and the relative spectral distribution. It can be classified according to broad and narrow definitions, including various types such as colorless optical glass, colored optical glass, laser glass, quartz optical glass, etc. When optical glass is produced and processed in the early stage, the surface of the glass needs to be polished.

[0003] After retrieval, the patent with the publication number of CN213647002U discloses a grinding disc specially used for optical glass lenses, which polishes both sides of the optical glass simultaneously by setting two synchronously rotating grinding disc sheets, so as to ensure the synchronism of polishing both sides of the optical glass. However, when the optical glass is actually polished, it is necessary to first polish the surface of the glass with a rough grinding sheet and then finely polish the surface of the glass with a fine grinding sheet. Therefore, this grinding disc has the same disadvantages as the existing technology when in use: it needs to be frequently disassembled and replaced with grinding disc sheets, and it is not fast and convenient to use. Secondly, dust will be generated during polishing, and both the grinding disc sheet and the optical glass will generate high temperatures. This grinding disc cannot achieve dust reduction and protection of the optical glass, so further improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a grinding disc specially used for optical glass lenses.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a grinding disc specially used for optical glass lenses, including a base, the inside of the base is designed to be hollow, the top wall of the base penetrates and is rotationally connected with a vertical shaft through a bearing, the top end of the vertical shaft is fixedly connected with a cross plate, a rotation driving assembly for driving the vertical shaft to rotate is arranged inside the base, U-shaped plates are fixed at both ends of the cross plate, cylinders are fixed on the upper and lower sides of one end of the U-shaped plate far away from the cross plate, grinding assemblies are installed at the telescopic ends of the two cylinders, an output assembly for driving the two grinding assemblies to rotate is arranged on one side of the U-shaped plate close to the cross plate, and a spraying assembly is fixedly connected between the two U-shaped plates.

[0006] Furthermore, the rotation driving assembly includes an electric telescopic rod fixed inside the base and a driven gear fixed on the surface of the bottom end of the vertical shaft, a toothed plate is fixedly connected to the telescopic end of the electric telescopic rod, and the toothed plate meshes with the driven gear.

[0009] Further, a narrow gear is fixed to the outer side wall of the sleeve. The output assembly includes a motor fixed to the upper surface of the U-shaped plate. The output shaft at the bottom of the motor passes through the top wall of the U-shaped plate and is fixedly connected to a wide gear. The narrow gear meshes with the wide gear.

[0010] Further, the spraying assembly includes a water inlet pipe and a cross pipe passing through the two U-shaped plates.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] As Figures 1 - 3 shown, it relates to a grinding disc dedicated to optical glass lenses, including a base 1 with a hollow interior design. The top wall of the base 1 is penetrated and rotatably connected to a vertical shaft 2 through a bearing. The top end of the vertical shaft 2 is fixedly connected to a cross plate 4. A rotation drive assembly 3 for driving the vertical shaft 2 to rotate is provided inside the base 1. U-shaped plates 5 are fixed at both ends of the cross plate 4. Cylinders 6 are fixed on both the upper and lower sides of the end of the U-shaped plate 5 away from the cross plate 4. Grinding assemblies 7 are installed at the telescopic ends of the two cylinders 6. An output assembly 8 for driving the two grinding assemblies 7 to rotate is provided on the side of the U-shaped plate 5 close to the cross plate 4. A spraying assembly 9 is fixedly connected between the two U-shaped plates 5.

[0023] The rotation drive assembly 3 includes an electric telescopic rod 32 fixed inside the base 1 and a driven gear 31 fixed on the surface of the bottom end of the vertical shaft 2. The telescopic end of the electric telescopic rod 32 is fixedly connected to a rack 33, and the rack 33 meshes with the driven gear 31.

[0024] The telescopic movement of the electric telescopic rod 32 can drive the rack 33 to move back and forth, and the rack 33 then drives the driven gear 31 and the vertical shaft 2 to rotate. During use, the telescopic movement of the electric telescopic rod 32 can be controlled to drive the cross plate 4 to rotate back and forth by 180°, so that the two U-shaped plates 5 can alternately change positions.

[0025] The grinding assembly 7 includes a sleeve 71 sleeved on the surface of the telescopic end of the cylinder 6. The sleeve 71 is rotatably connected to the telescopic end of the cylinder 6 through a bearing, and a grinding disc 72 is fixed at the end of the sleeve 71 away from the cylinder 6.

[0026] The elongation of the cylinder 6 drives the sleeve 71 and the grinding disc 72 to move, so that the grinding disc 72 can contact the surface of the optical glass.

[0027] The grinding discs 72 inside the two U-shaped plates 5 are respectively a rough grinding disc and a fine grinding disc.

[0028] Therefore, after the two U-shaped plates 5 alternately change positions, the rough grinding disc and the fine grinding disc can be used to polish the surface of the optical glass successively.

[0029] A narrow gear 73 is fixed on the outer side wall of the sleeve 71. The output assembly 8 includes a motor 81 fixed on the upper surface of the U-shaped plate 5. The bottom output shaft of the motor 81 passes through the top wall of the U-shaped plate 5 and is fixedly connected with a wide gear 82. The narrow gear 73 meshes with the wide gear 82.

[0030] After starting the motor 81, the wide gear 82 can drive the narrow gears 73 of the two grinding assemblies 7 to rotate simultaneously, so that the two grinding discs 72 rotate synchronously, ensuring the synchronism of polishing the two sides of the optical glass by the grinding discs 72.

[0031] The spraying assembly 9 includes a water inlet pipe 91 and a cross pipe 92 passing through the two U-shaped plates 5. One end of the water inlet pipe 91 is communicated with the middle part of the cross pipe 92. Both ends of the cross pipe 92 pass through the U-shaped plate 5 and are fixedly connected with spray nozzles 93.

[0032] In this embodiment, the other end of the water inlet pipe 91 is connected to the tap water pipe, so that water mist can be sprayed on the polishing position through the spray nozzles 93, playing a role in dust reduction and protecting the optical glass.

[0033] Solenoid valves 94 are fixedly connected to the surfaces of both ends of the cross pipe 92. The two solenoid valves 94 can be alternately opened, so that the two spray nozzles 93 can be alternately opened.

[0034] Working principle: First, drive the vertical shaft 2 to rotate through the rotary drive assembly 3, so that the grinding assembly 7 with the rough grinding disc rotates to one side of the optical glass clamping mechanism. Then start the cylinder 6 to drive the two grinding discs 72 to fit with the optical glass. Next, start the corresponding motor 81 to drive the two grinding discs 72 to rotate, realizing the polishing of both sides of the optical glass. After polishing, drive the vertical shaft 2 to reverse 180° through the rotary drive assembly 3, so that the other grinding disc 72 (fine grinding disc) rotates to one side of the optical glass clamping mechanism, and then use this grinding disc 72 to finely polish both sides of the optical glass. During the grinding process, the solenoid valve 94 on the corresponding side can be opened, and water mist can be sprayed through the corresponding spray nozzle 93 to achieve the functions of dust reduction and protecting the optical glass.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, many modifications and variations can be made according to the content of this specification.
