Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1.
Referring to fig. 1 and 2, the internal cooling grinding wheel with the self-water-absorbing blade of the invention comprises a grinding wheel matrix 1, a consolidation grinding tool 2 and an internal flushing port 3.
The grinding wheel matrix 1 is of an inverted disc-shaped structure, and a consolidation grinding tool 2 is arranged at the edge of the bottom of the grinding wheel matrix and used for grinding a workpiece. And a tool shank mounting hole 4 is formed in the center of the grinding wheel matrix 1 and is used for being connected with a tool shank. The internal flushing port 3 is mounted on the upper part of the grinding wheel base body 1 through a screw, and consists of a flushing inner ring 31, a flushing outer ring 32 and water absorbing blades 33, the flushing inner ring 31, the flushing outer ring 32 and the handle mounting hole 4 are coaxially arranged, and the water absorbing blades 33 are fixed between the flushing inner ring 31 and the flushing outer ring 32 and are uniformly distributed in the circumferential direction of the grinding wheel base body 1. The top of the grinding wheel base body 1 is provided with a water outlet hole 5 corresponding to the internal flushing port 3, and the cooling liquid is pressed into the internal flushing port 3 by the water absorbing blade 33 and then discharged from the water outlet hole 5.
In order to facilitate the centering installation of the internal flushing port 3 and the grinding wheel base body 1, the upper part of the grinding wheel base body 1 and the lower end of the flushing outer ring 32 are respectively provided with a clamping groove 6 which are matched with each other, and a self-centering rubber ring 7 is arranged in the clamping groove 6.
