Description

Technical Field

[0001] This utility model application relates to the field of automatic adjustment fixture technology, specifically an automatic adjustment fixture for optical glass polishing. Background Technology

[0002] Optical glass is a type of glass that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. It is a fundamental and important component of the optoelectronic technology industry and can be used to manufacture lenses, prisms, mirrors, and windows in optical instruments. To improve transparency and refractive index, reduce surface defects and irregular reflections, reduce light scattering, improve light utilization, and enhance wear resistance and corrosion resistance, optical glass needs to be polished.

[0003] During polishing, in order to ensure the stability of optical glass, it is necessary to fix the optical glass with a clamp. In order to adapt to optical glass of different thicknesses, most of the current clamps are automatically adjustable. However, when the existing clamps are used, if the clamping force is too large, it will easily put too much pressure on the optical glass, and if the clamping force is too small, it will easily fall off, resulting in low safety when the clamps are used. Utility Model Content

[0004] To address the issue of low safety during clamping in existing automatic adjustment fixtures for optical glass polishing, this invention provides an automatic adjustment fixture for optical glass polishing to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic adjusting fixture for polishing optical glass includes a fixture support and a servo cylinder. The servo cylinder is fixedly mounted on the top surface of the fixture support. A movable clamping plate is slidably disposed inside the fixture support. The output end of the servo cylinder slides through the fixture support and is fixed to the top surface of the movable clamping plate. A negative pressure chamber is formed inside the movable clamping plate. Several air guide holes are equidistantly formed at the bottom of the negative pressure chamber. An air guide pipe is fixedly fixed through the top surface of the movable clamping plate. An air pump is fixedly mounted on the side of the fixture support. The air guide pipe passes through the fixture support and is fixedly connected to the air pump inlet.

[0007] Furthermore, guide rods are fixed at the four corners of the top surface of the movable clamping plate, and each guide rod is slidably inserted into the top of the clamping bracket.

[0008] Furthermore, both the bottom surface of the movable clamping plate and the bottom of the clamping bracket are glued and fixed with shock-absorbing and anti-slip rubber pads, and the inside of the shock-absorbing and anti-slip rubber pads on the bottom surface of the movable clamping plate is provided with a groove that matches the air guide hole.

[0009] Furthermore, the air guide pipe near the air pump side is a rigid pipe, and the air guide pipe near the movable clamp side is a threaded telescopic pipe. Each air guide hole is fixed with a dust filter screen.

[0010] Furthermore, an air inlet pipe is fixedly connected to the air guide pipe above the air pump, and an air inlet valve is installed on the air inlet pipe.

[0011] Furthermore, a connecting pipe is fixedly connected to the air inlet end of the vent valve, and a protective cover is threaded onto the connecting pipe. A dust filter is fixed inside the protective cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by combining clamping and negative pressure adsorption, optical glass of different thicknesses can be clamped and fixed. While ensuring clamping stability, it also avoids excessive pressure on the optical glass due to excessive force. This solves the problem of low safety in the use of existing automatic adjustment fixtures for optical glass polishing and improves the safety of the fixture during use.

[0014] 2. In this utility model, the shock-absorbing and anti-slip rubber pad can protect the optical glass during clamping, and after polishing, the vent valve can be opened to quickly fill the negative pressure chamber with gas, thereby relieving the negative pressure and facilitating the subsequent handling of the optical glass.

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 An automatic adjusting fixture for optical glass polishing includes a fixture support 1 and a servo cylinder 2. The servo cylinder 2 is fixedly mounted on the top surface of the fixture support 1. A movable clamping plate 3 is slidably disposed inside the fixture support 1. The output end of the servo cylinder 2 slides through the fixture support 1 and is fixed to the top surface of the movable clamping plate 3. Guide rods 5 are fixed at the four corners of the top surface of the movable clamping plate 3, and each guide rod 5 is slidably inserted into the top of the fixture support 1. Shock-absorbing and anti-slip rubber pads 4 are glued to the bottom surface of the movable clamping plate 3 and the bottom surface of the fixture support 1. The movable clamping plate 3 has an internal opening. A negative pressure chamber 6 is provided, and several air guide holes 7 are equidistantly opened at the bottom of the negative pressure chamber 6. The shock-absorbing and anti-slip rubber pad 4 on the bottom surface of the movable clamp 3 has a groove inside that matches the air guide holes 7. An air guide pipe 9 is fixedly installed through the top surface of the movable clamp 3. An air pump 10 is fixedly installed on the side of the clamp bracket 1. The air guide pipe 9 passes through the clamp bracket 1 and is fixedly connected to the air inlet of the air pump 10. The air guide pipe 9 near the air pump 10 is a rigid pipe, and the air guide pipe 9 near the movable clamp 3 is a threaded telescopic pipe. A dust filter screen 8 is fixed inside each air guide hole 7.

[0022] Specifically, when it is necessary to clamp the optical glass, the optical glass is placed between two shock-absorbing and anti-slip rubber pads 4. The servo cylinder 2 operates, pushing the movable clamping plate 3 downward to cooperate with the clamping bracket 1 to clamp the optical glass. After clamping, the air pump 10 is turned on. At this time, the air valve 12 is in the closed state. The air pump 10 operates to draw gas from the negative pressure chamber 6 and the air guide hole 7 through the air guide pipe 9, so that the negative pressure chamber 6 generates negative pressure, adsorbing the optical glass onto the movable clamping plate 3, further fixing the optical glass. During adsorption, the dust filter screen 8 can protect the air guide hole 7 to prevent debris from entering the air guide hole 7. When releasing the clamp, the air pump 10 is turned off to release the negative pressure, and the servo cylinder 2 operates to drive the clamping bracket 1 upward.

[0023] As an optimization solution, such as Figure 1 and Figure 3 As shown, an air inlet pipe 11 is fixedly connected to the air guide pipe 9 above the air pump 10. An air inlet valve 12 is installed on the air inlet pipe 11. A connecting pipe 13 is fixedly connected to the air inlet end of the air inlet valve 12. A protective cover 14 is threaded onto the connecting pipe 13. A dust filter screen 15 is fixed inside the protective cover 14.

[0024] Specifically, when the polishing is finished and the clamping is required, the air pump 10 is turned off and the air valve 12 is opened to allow air to pass through the air guide tube 9. Under the action of negative pressure, the external gas passes through the dust filter 15 and enters the air guide tube 9 through the air valve 12 and the air inlet tube 11. It then enters the negative pressure chamber 6 through the air guide tube 9, which releases the adsorption of the movable clamp 3 on the optical glass, making it easy to remove the optical glass. When it is necessary to clean the dust filter 15, the protective cover 14 is turned off to remove the protective cover 14, and the dust filter 15 can be cleaned separately.

[0025] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
