Impeller supercharging solid self-lubricating grinding wheel matrix structure

Abstract

The invention discloses an impeller supercharging solid self-lubricating grinding wheel matrix structure. An impeller centrifugal pump structure is introduced into manufacturing of a grinding wheel; and the matrix structure mainly comprises a grinding wheel base plate and an impeller cover plate. An impeller is arranged on an impeller pedestal designed in the inner cavity of the grinding wheel base plate, the outer edge of the grinding wheel base plate is provided with a ring slot, and a one-way air inlet valve is arranged on the inner wall of the ring slot; during grinding, a main shaft of the grinding wheel drives the impeller in the inner cavity to simultaneously rotate at a high speed, so that high-pressure airflow is generated in the inner cavity; the high-pressure airflow bursts through the one-way air inlet valve, so that a solid lubricating agent filled in the ring slot is continually and properly precipitated on the surface of the grinding wheel under driving coaction of the high-pressure airflow, a centrifugal force, grinding heat and the like through micro pores on the outer wall of the inner cavity of the ring slot. The structure is simple and facilitates to popularize; and through the structure, the solid lubricating agent in the grinding wheel can be conveyed to a grinding arc area reliably with low cost, so that dry grinding can be realized.

Description

technical field [0001] The invention relates to an impeller pressurized solid self-lubricating grinding wheel base structure, which introduces the impeller structure into the grinding wheel manufacturing, and directly drives the solid lubrication in the grinding wheel inner cavity to the grinding arc area through the high-speed airflow generated by the impeller in the inner cavity of the grinding wheel, especially It is suitable for the design and manufacture of single-layer superabrasive grinding wheels for high-speed grinding of difficult-to-machine materials. Background technique [0002] In the grinding process, especially the grinding process of difficult-to-machine materials, most of the consumed heat is accumulated in the grinding arc area in the form of heat energy, and the difficult-to-machine materials themselves have the characteristics of poor thermal conductivity. If the heat cannot be channeled in time Going out will cause the temperature in the grinding arc ar...

AI Technical Summary

Problems solved by technology

During the grinding process of the grinding wheel, the air barrier formed by the high-speed rotation of the grinding wheel prevents the grinding fluid from effectively entering the grinding arc area. Meeting the actual needs of cooling in grinding processing is contrary to the requirements of green environmental protection
