Block-type structured diamond grinding wheel with adaptive supply of instantaneous cooling

A block-type structured diamond grinding wheel with adaptive supply of instantaneous cooling,

• wherein the grinding wheel is formed by a grinding wheel substrate (1) and several grinding wheel units, each grinding wheel unit includes an execution mechanism (2), a push mechanism (3), and an instantaneous cooling mechanism (4),
• the grinding wheel is arranged to rotate clockwise to process a workpiece by using the execution mechanism (2);
• a plurality of grooves are opened in an outer circumferential surface of the grinding wheel substrate (1);
• the grooves form an annular array structure on the outer circumferential surface of the grinding wheel substrate (1);
• each execution mechanism (2) includes a grinding unit (2.1), a hinge (2.2), a push rod (2.3) and a heat sink (2.4), wherein the grinding unit has an umbrella-shaped structure, an umbrella top of the grinding unit is arc-shaped, and a width of the grinding unit is the same as a width of the grinding wheel;
• an upper surface of each grinding unit is coated with a layer of a diamond abrasive, and the diamond abrasive is ablated by using a laser process technique to form a structured pattern, one or more holes are opened at a bottom of the grinding unit, through which the grinding unit is mounted to the heat sink (2.4);
• the bottom of the grinding unit (2.1) is hinged to the push rod (2.3) by the hinge (2.2), so as to drive the push mechanism (3) to press the instantaneous cooling mechanism (4) to spray nano fluid to implement instantaneous cooling of a grinding region where the grinding unit contacts the workpiece, when a tangential grinding force imposed on the grinding unit increases and exceeds a set threshold,
• wherein, the push mechanism (3) comprises an outer frame body (3.4), a main shaft (3.5), one or more springs (3.6), a piston (3.3), and a nut (3.2), a left end of the main shaft (3.5) passes through the outer frame body (3.4), the one or more springs (3.6) are disposed between the main shaft and the outer frame body (3.4), and the piston (3.3) is fastened to the main shaft (3.5) by the nut (3.2);
• and during operation, the piston (3.3) compresses the one or more springs (3.6) to drive the main shaft (3.5) to press a sprayer (4.1) of the instantaneous cooling mechanism (4).
