Grinding particle jetting assisting cup-shaped air bag grinding wheel

Abstract

The invention relates to a grinding particle jetting assisting cup-shaped air bag grinding wheel. The grinding particle jetting assisting cup-shaped air bag grinding wheel comprises a grinding wheel body, a transition sleeve, a connecting plate, a pressing plate, a sealing ring and an air bag. The grinding wheel body comprises a rotation shaft and a cup, and the cup is connected with one end of the rotation shaft. The rotation shaft is provided with a first cavity, the cup is provided with a second cavity, and the first cavity communicates with the second cavity. A first through hole communicating with the first cavity is formed in the side wall of the rotation shaft and used for guiding in of grinding and polishing cooling liquid. The cup further comprises a third cavity surrounding the second cavity, and the air bag is contained in the third cavity. The side, away from the rotation shaft, of the cup is provided with a base body, and the side, away from the cup, of the base body is provided with a grinding layer or a polishing pad. The transition sleeve is arranged on the rotation shaft in a sleeving manner, and the connecting plate is arranged on the transition sleeve in a sleeving manner, fixed to a spindle box of a machine tool and used for connecting of a grinding wheel body and the machine tool. According to the grinding particle jetting assisting cup-shaped air bag grinding wheel, through cooperation of the air bag and grinding particle jetting, the sub surface crack depth of workpieces is effectively reduced.

Description

technical field [0001] The invention relates to the field of grinding wheels, in particular to a cup-shaped airbag grinding wheel assisted by abrasive particle jetting. Background technique [0002] In the field of national defense astronomy, high-precision optical glass is mainly used in high-end technical fields such as laser fusion ignition devices, large astronomical telescopes, high-energy lasers, and satellite optical systems. For example, the Hubble Space Telescope, the US National Ignition Device and my country's "Shenguang" series of laser devices. In the field of civilian optoelectronic products, as a key component of information transmission, it also plays an extremely important role in products such as optical communications, mobile phones and digital cameras. The machining of high-precision optical glass is mainly achieved through efficient grinding and deterministic polishing. Grinding mainly completes the forming and controls a certain surface accuracy, whil...
