Open feed liquid self-sucking type inner cooling grinding wheel device for face grinding

Abstract

The invention discloses an open feed liquid self-sucking type inner cooling grinding wheel device for face grinding, which has two structures, namely a combined structure and an integral structure. The combined structure comprises a knife handle, a water collection sleeve, a grinding wheel base body, a gasket, a screw, and a grinding wheel block. One end of the knife handle is connected with a spindle of a grinding machine so as to drive the whole grinding wheel to rotate at a high speed under the high-speed rotation action of the spindle; the water collection sleeve is connected with the grinding wheel base body through threads; a cylindrical through hole on the upper part of the grinding wheel base body is matched with a cylindrical surface at the lower end of the knife handle for positioning; the grinding wheel base body is fixed on the knife handle 1 through the gasket and the screw; and the grinding wheel block is sintered at the lower end of the grinding wheel base body, wherein an inclined hole of which the direction is consistent with the flow direction of cooling liquid is formed on the grinding wheel base body. A spiral groove is formed on the cylindrical surface in the water collection sleeve; the direction of turning of the spiral groove is right-handed; and the spiral groove can prevent the cooling liquid from overflowing under the action of centrifugal force. The grinding wheel block has a split structure in which a chute can be naturally formed between two blocks, and the direction of the chute is consistent with that of the centrifugal force applied to the cooling liquid.

Description

technical field [0001] The invention relates to an open liquid-supply self-priming internal cooling grinding wheel device for end face grinding, specifically refers to a grinding wheel device that uses an open supply of grinding fluid for internal cooling during the grinding process, and is especially suitable for high-speed Face grinding method. Background technique [0002] With the development of high-speed ultra-high-speed grinding technology, the wide application of difficult-to-machine materials in industry, and the improvement of surface quality requirements in grinding, the control of grinding temperature in the grinding process is also particularly important. And improving the liquid supply mode of the grinding fluid and improving the cooling effect can greatly reduce the grinding temperature and improve the grinding quality. Internal cooling is a way to effectively improve the cooling effect in the grinding liquid supply mode. There are many grinding wheel devices...

On June 13, 1995, U.S. Patent No. 5,423,717 provided such a grinding wheel. The cooling liquid enters the inner cavity of the grinding wheel by means of a central opening for liquid supply, and then is thrown out through two layers of channels on the circumference of the grinding wheel. This structure The assembly can only cool a few points on the circumference of the grinding wheel and is only suitable for edging thin-walled parts
