Problems solved by technology
Using the airbag polishing method, although high processing accuracy can be obtained, different processing surfaces require different polishing heads, the processing adaptability is not strong, and the polishing head needs to be constantly trimmed to maintain the processing accuracy, which affects the processing efficiency and accuracy. Impact; manual polishing does not require automated polishing equipment, and the processing cost is low, but manual polishing has problems such as low processing efficiency and unstable processing accuracy; jet polishing relies on the impact of abrasive jets to remove materials, and is suitable for small-diameter deep concave aspheric surfaces polishing, but the polishing removal rate is low

The invention relates to an amplitude-controllable small-caliber aspheric polishing device. The device is formed by a polishing head, a magnetostrictive body element and a base. The polishing head is in interference fit with a hole of the magnetostrictive body element through a shaft. The magnetostrictive body element is in interference fit with a cross boss of the base through a cross groove composed of four thin magnetostrictive rods. The magnetostrictive body element is made of gallium magnetostrictive material Fe83Ga17. The cross groove is formed in the bottom of the magnetostrictive body element through linear cutting, and the four thin magnetostrictive rods serve as the four edges of the cross groove. An open pore is formed in the top of the magnetostrictive body element, and the diameter of the open pore is matched with the shaft of the polishing head. Coils are wound around all the thin magnetostrictive rods. The amplitude-controllable small-caliber aspheric polishing device has the advantages of being small in size, simple in structure, convenient to use and the like; small parts can be polished through the polishing device; moreover, the polishing head does not need to be replaced when the polishing device is used for machining parts made of different materials and parts in different shapes.
Description
technical field [0001] The invention relates to a novel polishing device, in particular to a small-diameter aspheric polishing device, the core part of which is a vibrating element made of iron-gallium magnetostrictive material. The polishing device utilizes the magnetostrictive properties of the Fe-Gallium alloy, which can output vibration at the vibration end of the polishing device to provide high-efficiency and high-quality polishing for small-diameter aspheric parts. technical background [0002] Small-diameter aspheric parts are a very important product component. For example, the use of small-diameter aspheric parts in optical systems can improve the imaging quality, improve the optical performance of the instrument, and reduce the number of optical parts, thereby simplifying the structure of the instrument and lightening the instrument. weight and reduce production costs. With the rapid development of optoelectronic communications, bioengineering, and aerospace indu...
