A kind of detachable combined type diamond-impregnated wheel
Technical field
The utility model relates to a kind of diamond-impregnated wheel.
Background technology
At present, existing diamond-impregnated wheel is divided into two big classes: a class be after metal powder material is aided with steady pin and is cold-pressed into cutter head by resinoid bond or metal adhesive sintering on abrasive wheel substrate, another kind of is with the direct vacuum-sintering of emery wheel cutter head, is welded on the abrasive wheel substrate then.First kind emery wheel is more loaded down with trivial details when making the steady pin part of metallic matrix, and working (machining) efficiency is not high.It is better that the cutter head of the second class emery wheel and abrasive wheel substrate combine fastness, but cost is very high, and along with the development of society, especially the rise of building industry, people increase year by year to the demand of diamond-impregnated wheel, simultaneously also the performance of diamond-impregnated wheel is proposed more and more higher requirement, as require diamond-impregnated wheel not only will have grinding function preferably, and processing and operation require easy.
Summary of the invention
The utility model provides a kind of grinding performance good and dismountable combined type diamond-impregnated wheel.
The technical solution adopted in the utility model is: bowl-shape matrix middle part has a bowl-like depression, the bowl-like depression center is provided with a mounting center hole, the cross section of bowl-shape matrix outer is a ring-type, the circumferential edge of this crosscut has semi-circular projection, fixedly install on the bowl-like depression crosscut circumferentia more nearby fixedly on the cutter head, but dynamic cutter head is fixed on described semi-circular raised position place, but the dynamic cutter head outer surface is grinding block fixedly, but metallic stud is embedded in the dynamic cutter head, but dynamic cutter head is fixedly connected on the bowl-shape matrix by metallic stud.
The beneficial effects of the utility model are:
But 1, employing dynamic cutter head and the fixedly combining structure of the double cutter head of cutter head, and being distributed with of cutter head is beneficial to chip removal, heat radiation and water cooling, but the dynamic cutter head of outer ring is detachable, can change or not install, the handled easily service life that increases emery wheel.
But 2 dynamic cutter heads are positioned at the semi-circular raised position place of metallic matrix, make emery wheel have cutting function, have enlarged the scope of application of this emery wheel.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that Fig. 1 looks cutaway view on the left side of A-A position.
Among the figure: but 1. dynamic cutter head, 2. mounting center hole, 3. bowl-shape matrix, 4. fixing cutter head, 5. manhole, 6. copper rivet, 7. metallic stud is 8. installed nut, 9. grinding block.
The specific embodiment
As shown in Figure 1, there is a bowl-like depression at bowl-shape matrix 3 middle parts, and the depression center is provided with a mounting center hole 2, and fixation is played in this mounting center hole 2 when emery wheel is installed.The cross section of bowl-shape matrix 3 outers is a ring-type, has semi-circular projection at circumferential edge.On bowl-like depression circumferentia more nearby a circle copper rivet 6 is set, fixedly cutter head 4 is fixedly connected on the bowl-shape matrix 3 by this circle copper rivet 6.Have several manholes 5 in described semi-circular raised position, 5 thermolysis of manhole.But dynamic cutter head 1 is fixed on this semi-circular raised position place, but at the fixing grinding block 9 of dynamic cutter head 1 outer surface, grinding block 9 mixes with special ratios by diamond fine grained and some other metal powder materials.During manufacturing, but metallic stud 7 can be embedded among the dynamic cutter head 1, the external part of metallic stud 7 has screw thread, matches with screw thread dynamic cutter head 1 is fixedly connected on the bowl-shape matrix 3 but nut 8 is installed, but realize detachable connection the between dynamic cutter head 1 and the bowl-shape matrix 3.
When emery wheel is worked; but by dynamic cutter head 1 and fixedly the diamond particles that protrude of cutter head 4 surface carry out scratching and ditch plough; realization is to being ground the effect of thing; but the chipping grade of the diamond particles on dynamic cutter head 1 top layer inefficacy in grinding process; but the diamond particles of these inefficacies can come off along with coming off of other metal material in the dynamic cutter head 1; thereby keep always having intact diamond particles work, realize the whole process of grinding.
