[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 A polishing device for manufacturing low-expansion optical glass comprises a device base 1, a fixing frame 2 is fixed to the outer wall of the device base 1, an adjusting electric cylinder 3 is fixed to the upper surface of the fixing frame 2 by bolts, a polishing mechanism for polishing optical glass is fixed to the telescopic end of the adjusting electric cylinder 3 through the fixing frame 2, and a sealing mechanism for sealing during polishing is provided below the polishing mechanism;

[0029] The polishing mechanism includes a polishing motor 4, which is fixed to the telescopic end of the adjusting electric cylinder 3;

[0030] The sealing mechanism includes a protective shell 5, which is fixed at the lower end of the polishing motor 4. A connecting groove 51 is opened inside the protective shell 5. A spring 52 is fixed inside the protective shell 5. The end of the spring 52 is abutted and connected with a limit plate 53. A movable plate 54 is fixed at the lower end of the limit plate 53. A sealing gasket 55 is fixed at the lower end of the movable plate 54. A dust removal mechanism for filtering dust is installed on the upper surface of the protective shell 5. A transmission rod 41 is fixed to the power output shaft of the polishing motor 4. A polishing disk 42 is fixed to the end of the transmission rod 41. A limit piece 7 is provided on the upper surface of the equipment base 1. Two cylinders are fixed to the outer wall of the limit piece 7 by bolts. The telescopic end of the cylinder passes through the limit piece 7 and is fixed with a clamping piece. The clamping piece can be a clamping plate or a clamping rod for clamping and limiting the optical glass. A working chamber 6 is provided inside the limit piece 7.

[0031] By adopting the above technical solution, before using the polishing equipment for manufacturing low-expansion optical glass, the equipment base 1 is first placed in a suitable position. When in use, the optical glass to be processed is placed in the working chamber 6 in the limiter 7, and two cylinders are fixed to the outer wall of the limiter 7. The telescopic ends of the two cylinders are respectively provided with clamping blocks, which can clamp the side walls of the optical glass, thereby reducing the displacement of the optical glass. The adjusting electric cylinder 3 on the fixed frame 2 drives the polishing motor 4 to move vertically. Since the protective shell 5 is fixedly connected to the polishing motor 4, the protective shell 5 can be moved. The movable plate 54 can push the limiting plate 53 to move, and through the spring 52 arranged in the connecting groove 51, when the sealing gasket 55 contacts the upper surface of the limiter 7, the movable plate 54 can push the limiting plate 53 to move, thereby compressing the spring 52, so that the protective shell 5 and the limiter 7 can be sealed. When the polishing disc 42 contacts the upper surface of the optical glass, it stops moving, and the polishing motor 4 is started to drive the transmission rod 41 to rotate, thereby driving the polishing disc 42 to polish the optical glass, and the dust generated by polishing is blocked by the protective shell 5, thereby effectively reducing the dust floating in the air.

[0032] Specifically, Figure 1-Figure 4 As shown, the dust removal mechanism includes a dust removal member 8, which is connected to the upper surface of the protective shell 5. A negative pressure fan 81 is installed at the upper end of the interior of the dust removal member 8. Two filter screens 82 are installed inside the dust removal member 8. Blocks 83 are fixed at both ends of the two filter screens 82. The outer surface of the block 83 is slidably connected to a slot 84 opened on the inner wall of the dust removal member 8. A connecting plate 85 fixed to the filter screen 82 is movably connected to one side of the dust removal member 8.

[0033] By adopting the above technical solution, the negative pressure fan 81 arranged in the dust removal part 8 is started, and the air between the protective shell 5 and the limiter 7 can be extracted. A through hole is opened on the working chamber 6, and the through hole is connected to the external air through the pipeline inside the equipment base 1, so that the dust blocked between the protective shell 5 and the limiter 7 is sucked into the dust removal part 8, and the dust is blocked by two filter plates 82, and then the air is discharged to the outside, which plays a role in dust removal. Through the provided block 83 and the slot 84, the connecting plate 85 can be manually pulled to remove the filter plate 82 for easy cleaning and replacement.

[0034] Working principle: the polishing motor 4 is driven to move vertically by the adjusting electric cylinder 3 on the fixed frame 2, and the protective shell 5 can move. Through the spring 52 arranged in the connecting groove 51, when the sealing gasket 55 contacts the upper surface of the limiter 7, the movable plate 54 can push the limiter plate 53 to move, compress the spring 52, and seal the protective shell 5 and the limiter 7. When the polishing disc 42 contacts the upper surface of the optical glass, it stops moving, and the polishing motor 4 is started, thereby driving the polishing disc 42 to polish the optical glass, and the dust generated by the polishing is blocked by the protective shell 5. The negative pressure fan 81 arranged in the dust removal part 8 is started to extract the air between the protective shell 5 and the limiter 7, and a through hole is opened on the working chamber 6, which is connected to the external air through the pipeline inside the equipment base 1, so that the dust blocked between the protective shell 5 and the limiter 7 is sucked into the dust removal part 8, and the dust is blocked by two filter plates 82, thereby playing a dust removal role.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
