Specific embodiment
Referring to FIG. 1, FIG. 2 and FIG. 3, a kind of heat dissipation abrasive grinding wheel, center shell 1 including round pie and around being set to center
Grinding block 2 on 1 periphery of shell, grinding block 2 are in flaabellum shape, and the center of center shell 1 is provided with shaft hole 11, all grinding blocks 2
It is uniformly distributed with same direction of rotation, there are gaps (to show that the gap specially will grinding in figure between adjacent grinding block 2
The distribution of block 2, which becomes, dredges, and the practical finished product gap is smaller)；In terms of the top surface of center shell 1, the rear portion of previous grinding block 2 covers latter
The front of a grinding block, the outer rim of all grinding blocks 2 are linked to be a circle.
Grinding block 2 has the structure of similar flabellum simultaneously respectively independent, increases the contact area of grinding wheel and air, that is, increases
Heat dissipation area.In grinding wheel rotation, it can dry as fan, that is, increase the flow velocity of wheel face heat transferring medium, in addition to
Outside the fluid heat transfer of prior art plane of grinding wheel rotation, the blowing perpendicular to 1 top surface of center shell is also added, makes grinding wheel heat dissipation speed
Faster, and due to there is the blowing perpendicular to grinding wheel, the big flow velocity of centre makes the periphery of grinding wheel nearby generate negative pressure to degree, and
Burnishing part is exactly the periphery in grinding wheel, this accelerates the gas flow rate of workpiece surface also, the residue for being ground out
It can be easier that air-flow is followed to fly away.The temperature of grinding wheel and workpiece rises slower when therefore polishing, and is conducive to protect grinding wheel and workpiece
From high temperature injury.
Center shell 1 is formed by intermetallic composite coating, and grinding block 2 is sintered by abrasive material and resin.It is produced respectively when production, the later period
Assembling obtains finished grinding wheel.Using resin as the wheel strength of bonding agent height, self-sharpening is good, but heat-resisting slightly worse.The use of the new type
Just it is utilized the feature, a height of grinding block 2 of resin wheel intensity is made flaabellum shape and provides the foundation condition, and the utility model
Grinding wheel good heat dissipation compensate for the deficiency of resin wheel again.
Referring to Fig. 4, Fig. 5 and Fig. 6, center shell 1 is assembled by upper housing 12 and lower case 13, and the inside of upper housing 12 is set
It is equipped with the positioning pit 121 of circle distribution, the inside of lower case 13 is provided with positioning plug-in unit 131 corresponding with 121 position of positioning pit,
Grinding block 2 is extended into center shell 1 connector 21, is provided in connector 21 and the positioning matched slot of plug-in unit 131
211, about 211 through-connections 21 of slot.
Connector 21 can be made of abrasive material and resin, i.e., integrally form with grinding block 2, with being sintered after mold compression moulding
And it obtains；It can also be made of wolfram steel, a portion is imbedded in grinding block 2, i.e., in 2 pressing process of grinding block, by wolfram steel
It suppresses in one section of merging abrasive material of connector, is then sintered together.
One grinding block 2 has twice slot 211, and correspondingly, two positioning plug-in units 131 and the cooperation of twice slot 211 are solid
A fixed grinding block, and positioning plug-in unit 131 is arc bump.Arc bump limit is accurate, and assembles rapidly, every two arc
Convex block, which assembles a grinding block 2, fastens grinding block 2 more.
Single connector 21 makees section along 1 periphery of center shell, and gained is asymmetrical in shape, correspondingly, the side of upper housing 12
Edge is provided with the upper recess 122 to match with the asymmetrically shape top half, and the edge of lower case 13 is also equipped with this not
The lower recess 132 that symmetric shape lower half portion matches.Connector 21, which is fixed, when assembly is clipped in recess 122 and lower recess
Between 132, grinding block 2. is further fastened
There are many fixed forms of upper housing 12 and lower case 13, can use buckle, can use bolt, can also the two knot
It closes.The mode being fixed by bolts in the present embodiment, the inside of upper housing 12 are provided with reinforcing prop 123, are arranged in lower case 13
There is through-hole 133 corresponding with reinforcing prop 123, reinforcing prop 123 is hollow and is provided with internal screw thread, and center shell 1 is logical by successively precession
Hole 133, reinforcing prop 123 bolt fastening.
The grinding block 2 of the grinding wheel can be replaced, and center shell 1 can reuse.The assembling process of grinding wheel is as follows, first will
Lower case 13 is put in plane, and grinding block 2 is loaded one by one, wherein positioning plug-in unit 131 penetrates in slot 211, due to connector
21 sections are asymmetric, connector 21 contacted with lower recess 132 can apparent grinding block 2 it is whether anti-loaded, loaded grinding block 2
Upper housing 12 is covered afterwards, upper notch 122 can facilitate with the cooperation of grinding block 2 to be aligned, and can make to position in center shell 1 without seeing
Plug-in unit 131 is placed in positioning pit 121, and grinding wheel is finally installed bolt in turn.In order to facilitate later period assembly, when designing mold
The thickness of grinding block 2 is smaller than the thickness of center shell 1.
The center of upper housing 12 and lower case 13 is provided with bulge loop 111, and two bulge loops 111 offset to form shaft hole 11.
Shaft hole 11 just uses the prior art for connecting with the shaft of sander, therefore does not limit the specific shape of shaft hole 11 in attached drawing
Shape.The grinding wheel in addition to the rapid heat dissipation the advantages of other than also have the function of correcting worker's faulty operation.It can not make in grinding wheel operating instruction
It is polished with the plane of grinding wheel, periphery should be used, but part worker usually refined with the plane of grinding wheel to workpiece by greedy facilitate,
It is easy to make to cause danger, plane is not present in its grinding block 2 of the grinding wheel of the utility model, and the two sides up and down of grinding wheel are discontinuous, uneven
It is whole, it is not used to polish, sanding operation can only be carried out with the foreign aid of grinding block 2, be conducive to correct worker's faulty operation, ensure life
Produce process safety.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
It is considered as the protection scope of the utility model.
