CFRP grinding wheel for high-speed and superhigh-speed grinding

Abstract

The invention relates to the technical field of CFRP grinding wheels, and discloses a CFRP grinding device for high-speed and superhigh-speed grinding. The CFRP grinding wheel for high-speed and superhigh-speed grinding comprises a rotary shaft, wherein a sleeve is movably mounted outside the rotary shaft; a baffle ring positioned at the right side of the sleeve is fixedly connected to the peripheral wall of the rotary shaft; a rotary bin is movably mounted outside the sleeve; a threaded ring is fixedly connected on the inner peripheral wall of the rotary bin; a right threaded slot is formed in the outer peripheral wall of the sleeve; an extrusion ring positioned at the right side of the threaded ring is fixedly connected to the inner peripheral wall of the rotary bin; and three metal binsare fixedly connected to the outer peripheral wall of the sleeve. According to the CFRP grinding wheel for high-speed and superhigh-speed grinding disclosed by the invention, a ring-shaped slot is adaptive to the inclined surface at the right side of the outer peripheral wall of a fixed ring, concentricity between the grinding wheel and the rotary shaft is guaranteed through tapered self-concentric characteristic, and the bonding area is increased, so that bonding strength of the grinding wheel is improved, and positioning precision and safety after the grinding wheel is mounted are higher.

Description

technical field [0001] The invention relates to the technical field of CFRP grinding wheels, in particular to a CFRP grinding wheel for high-speed and ultra-high-speed grinding. Background technique [0002] Ultra-high-speed grinding refers to the grinding process with a grinding speed of more than 150m / s. The low processing efficiency of the grinding process realizes the perfect combination of high-efficiency processing and precision machining, and brings revolutionary changes to the traditional grinding process. The key to the realization of ultra-high-speed grinding technology lies in the development of high-speed and ultra-high-speed conditions. grinding wheel, because the grinding wheel needs to work at an ultra-high linear speed, it puts forward extremely high requirements on the static and dynamic performance of the grinding wheel. At present, the base of the grinding wheel is usually made of metal materials such as aluminum alloy and steel, which has low cost and goo...
