The utility model realizes the purpose through the following technical proposal, a high-precision diamond broaching groove grinding wheel comprises a base body and wear-resisting pieces arranged on the periphery of the base body, wherein the surface of the wear-resisting pieces is provided with a circle of assembling grooves distributed annularly, and each assembling groove is provided with a tool bit mechanism;

the tool bit mechanism mainly comprises a diamond tool bit and an iron block.

Preferably, the diamond tool bit and the iron block are fixed in a sintering mode, and the iron block and the assembling groove of the wear-resisting plate are fixed in a welding mode.

Preferably, one end of the diamond tool bit is provided with a convex block, one end of the iron block is provided with a groove, and the convex block is matched with the groove.

Preferably, the lug is internally provided with an anti-falling groove, the groove is internally provided with an anti-falling head, and the anti-falling groove is matched with the anti-falling head.

Preferably, the size of one part of the anti-falling head close to the iron block is smaller than that of one part close to the diamond tool bit, and the lug and the groove are horizontally fixed by clamping the anti-falling head into the anti-falling groove.

Preferably, the rear end of the wearpad is of a full-circle design.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a divide into iron plate and diamond segments two parts with tool bit mechanism, because convenient sintering between diamond segments and the iron plate, convenient welding between iron plate and the wear pad, therefore fixing on the base member that tool bit mechanism can be firm, it is better to use stability to tool bit mechanism adopts half iron plate of half diamond segments, has also practiced thrift use cost.

2. Iron plate and diamond segments adopt the assembly methods of lug and recess, just can be in the same place in the laminating before the sintering, convenient sintering, still adopt the mode of anticreep head card income anticreep groove to avoid alternate segregation between lug and the recess moreover, make between diamond segments and the iron plate difficult separately, prolonged life.

3. The rear end of the wear-resistant piece is designed into a whole circle, so that the wear-resistant piece can be effectively prevented from falling off, and the bonding strength with the cutter head mechanism is improved; the structural design of the wear-resistant sheet enables the diamond tool bit structure to be continuous without gaps, edges are not prone to jumping during grinding, and the grinding effect is smooth and flat.

Fig. 3 is the assembly schematic diagram of the diamond tool bit and the iron block of the utility model.

In the figure: 1. the diamond tool comprises a base body, 2, a wear-resistant sheet, 3, a tool bit mechanism, 4, a diamond tool bit, 5, an iron block, 6, a bump, 7, a groove, 8, an anti-drop head, 9 and an anti-drop groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a high-precision diamond grooving grinding wheel comprises a base body 1 and wear-resistant pieces 2 arranged on the periphery of the base body 1, wherein a circle of annularly distributed assembly grooves are formed in the surfaces of the wear-resistant pieces 2, and a cutter head mechanism 3 is arranged on each assembly groove; tool bit mechanism 3 mainly comprises diamond segments 4 and iron plate 5, tool bit mechanism 3 adopts the mode of half diamond segments 4 half iron plate 5, can practice thrift the use of diamond segments 4 material, thereby save use cost, it is fixed to sinter between diamond segments 4 and the iron plate 5, iron plate 5 is fixed with wear pad 2's assembly groove welded connection, because the material between diamond segments 4 and the base member 1 is different, the two bonding strength is weak after the welding, consequently, adopt iron plate 5 as the medium between diamond segments 4 and the base member 1, diamond segments 4 and iron plate 5 sintering back together, bonding strength is stronger, and iron plate 5 and base member 1 welding back, bonding strength is also stronger, consequently, tool bit mechanism 3 fixes after on the assembly groove, the fastness is stronger, be difficult for droing.

As shown in figure 3, one end of the diamond tool bit 4 is provided with a convex block 6, one end of the iron block 5 is provided with a groove 7, the convex block 6 and the groove 7 are matched, the convex block 6 is inserted into the groove 7, so that the diamond tool bit 4 and the iron block 5 are conveniently attached to each other, and when the diamond tool bit is sintered, the convex block 6 and the iron block are fixed together without the help of tools, and the tool bit mechanism 3 is convenient to process and produce. The inside anticreep groove 9 that sets up of lug 6, recess 7 is inside to set up anticreep head 8, adaptation between anticreep groove 9 and the anticreep head 8, anticreep head 8 is less than the size that is close to diamond segments 4 partly near the size of iron plate 5 partly, go into anticreep groove 9 through anticreep head 8 card and make lug 6 and recess 7 level fixed, because anticreep head 8 is close to diamond segments 4's one end size great, card goes into just unable level after anticreep groove 9 and pulls open, thereby make laminating inseparabler and firm between lug 6 and the recess 7, because the centrifugal force of emery wheel during operation principle centre of a circle department is the biggest, block between anticreep head 8 and the anticreep groove 9, can restrict diamond segments 4 and thrown away because of the effect of centrifugal force, thereby diamond segments 4 steadiness has been increased.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
