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.

The utility model aims at providing a be difficult to leave the mar that is difficult to get rid of on concrete ground, and the terrace grinding wheel that the tool bit is difficult to damage or drop.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

The first embodiment is as follows:

as shown in fig. 1-2, the present embodiment provides a terrace grinding wheel, which comprises a base body, a plurality of tool bits 4 and a plurality of supporting blocks 5 for supporting the base body, the base body is fixedly connected with a grinding device, each tool bit 4 and each supporting block 5 are all fixed on the base body, the supporting block 5 is not higher than the tool bit 4, by arranging the supporting block 5, the supporting block 5 assists in supporting the grinding device, the pressure of the tool bit 4 is reduced, the occurrence of the situation that a blade is damaged or falls off is effectively avoided, and because the pressure borne by the tool bit 4 is reduced, the situation that the tool bit 4 cuts into the terrace too deeply during the work is effectively avoided, and the situation that a deeper scratch which is difficult to remove is left on the.

In addition, the cutting depth of the cutter head 4 is further limited by the height of the supporting block 5, in this embodiment, the height of the supporting block 5 is slightly smaller than that of the cutter head 4, preferably, the height difference between the supporting block 5 and the cutter head 4 is 0.5mm, and the supporting block 5 can assist the cutter head 4 to remove the floor coating by making the supporting block 5 have a certain sharpness, but the sharpness of the supporting block 5 should be smaller than that of the cutter head 4.

Specifically, the base member includes little annular part 1, curved surface portion 3 and big annular part 2, preferably, curved surface portion 3 is circular cone curved surface portion, little annular part 1 is parallel to each other with big annular part 2, curved surface portion 3 sets up between little annular part 1 and big annular part 2, and the lateral wall of little annular part 1 passes through curved surface portion 3 and big annular part 2's inside wall fixed connection, little annular part 1 nestification is installed on grinding device's main shaft, and with main shaft fixed connection, each tool bit 4 and supporting shoe 5 all keep away from the one end fixed connection of little annular part 1 with big annular part 2, the front end of supporting shoe 5 is provided with V type closed angle 501, the rear end is provided with V type recess 502.

In order to facilitate heat dissipation and chip removal of the substrate, the curved surface portion 3 is provided with a plurality of through holes 301 for heat dissipation and chip removal.

In order to improve the working efficiency and the stability of the base body, the cutter bits 4 and the supporting blocks 5 are uniformly arranged along the circumferential direction of the large annular part 2.

In order to extend the useful life of the cutting head 4, the cutting head 4 is a polycrystalline diamond cutting head.

In order to prevent the cutter head 4 and the supporting block 5 from falling off from the base body, a plurality of grooves are formed in the base body, the cutter head 4 is fixed in one groove in a welding mode, the supporting block 5 is connected with the base body in a welding mode, and particularly, the grooves are formed in one end, far away from the small annular portion 1, of the large annular portion 2.

It should be noted that the supporting block 5 is any block made of metal material capable of supporting the substrate, the shape of the supporting block 5 is not limited to the front end provided with the V-shaped sharp corner 501 and the rear end provided with the V-shaped groove 502, and any shape capable of supporting the substrate may be adopted, for example, the supporting block 5 may also be a rectangular parallelepiped supporting block.

In addition, when the height of the cutter head 4 is greater than that of the supporting block 5, the supporting block 5 is not in contact with the floor and does not work, when the cutter head 4 is worn to be level with the supporting block 5, the cutter head 4 can play a role of auxiliary support, and therefore the height difference between the cutter head 4 and the supporting block 5 cannot be too large.
