Compared with prior art, the useful effect of the utility model is:
1. when not affecting grinding efficiency and wheel strength, emery wheel dish body is set up heat radiation groove and thermal vias, builds closed and intersection heat-radiation belt, ensure that heat radiation area can mediate emery wheel dish body internal heat in time, alleviate emery wheel weight, decrease load when emery wheel dallies.Heat radiation groove divides annular and center to disperse two kinds of forms, and the design of heat radiation groove mates mutually with wheel grinding heat production inequality.
2. the emery wheel heat emission fan impeller structure designed by effectively make use of grinding process emery wheel and rotates the kinetic energy produced, it is not necessary to additionaling power, in conjunction with described heat radiation groove and heat dissipation channel, and positive heat radiation; Heat radiation flabellum rotates, and drives air flow in emery wheel dish body central cavity, air-flow turnover thermal vias and heat radiation groove, it is achieved heat loss through convection.
3. the utility model emery wheel utilizes wind-cooling heat dissipating, can effectively save the energy, avoids the environmental pollution using cooling fluid to cause; Also the restriction of material properties no longer it is subject to, it is possible to process more material.
4. the utility model emery wheel structure is simple, easy for installation, it may also be useful to as usual, is convenient to promote.

Embodiment
The utility model is described further below in conjunction with embodiment and accompanying drawing.
The utility model provides a kind of fan heat dissipation type emery wheel and (is called for short emery wheel, see Fig. 1-4), comprise emery wheel dish body 1, motor and transmission rig (known technology does not draw in figure), it is characterised in that this emery wheel also comprises aluminium core 2 and heat radiation flabellum 3; Described emery wheel dish body 1 has central cavity 11, center through hole 12, heat radiation groove 13 and thermal vias 14; Described heat radiation groove 13 is positioned at the lower surface of emery wheel dish body 1, comprises center and disperses groove 131 and annular recesses 132; Described center is dispersed groove 131 and is connected with annular recesses 132, reaches and increases heat radiation area, heat radiation evenly and the unobstructed object of radiating airflow. Described thermal vias 14 is the through hole that the upper surface from emery wheel dish body 1 is through to central cavity 11, and thermal vias 14 is distributed on emery wheel dish body 1 symmetrically; The center of circle of thermal vias 14 is all in taking the center of circle of center through hole 12 as, on the same concentric(al) circles in the center of circle, so that emery wheel internal stress is uniformly distributed during grinding, avoiding unbalance stress to cause emery wheel crackle or peeling off phenomenon occur; Described concentric circular diameter is less than the diameter of central cavity 11. The described thermal vias 14 of embodiment is four, and the line in four thermal vias centers of circle forms square.
The further feature of the utility model emery wheel is, by the center of the outer edge of emery wheel dish body 1 to emery wheel dish body 1, the groove width that groove 131 is dispersed at center increases gradually; By the center of the outer edge of emery wheel dish body 1 to emery wheel dish body 1, the ring footpath of annular recesses 132 increases gradually, and the distribution interval between annular recesses 132 reduces gradually.
The described heat radiation flabellum 3 of the utility model emery wheel embodiment is 3-8, and is uniformly distributed by center of circle annular of the center of circle, lower surface of aluminium core 2.
Described aluminium core 2 is arranged on the center through hole 12 of emery wheel dish body 1.
Described heat radiation flabellum 3 is arranged on central cavity 11 place of emery wheel dish body 1, and the concave surface of heat radiation flabellum 3 is down, and rotation direction is consistent with emery wheel sense of rotation.Heat radiation flabellum 3 rotates, and drives the air flow in emery wheel dish body central cavity 11, and warm air can be discharged by heat radiation groove 13 and thermal vias 14 simultaneously.
After described ring footpath refers to that annular recesses 132 is cut by arbitrary center of circle by center through hole 12 and the plane that is parallel to the axial vector of center through hole 12, the diameter of annular recesses 132 rounded section.
The principle of work of the utility model emery wheel with workflow is: the same with conventional emery wheel during stone, first near workpiece, then carries out grinding. In grinding process, emery wheel rotates, and drives heat radiation flabellum 3 to rotate, heat radiation flabellum 3 rotates, the gas in central cavity 11 being driven to flow, thus realize the extraneous circulation with air-flow in central cavity 11 and exchange, air-flow also realizes heat loss through convection by heat radiation groove 13 and thermal vias 14 simultaneously.
