Abstract
The utility model discloses a kind of diamond grinding knife tools, including matrix, matrix includes the central boss and outer toroid platform of centre protrusion, the center of central boss is equipped with mounting hole, it is arranged in equal spacing with several diamond segments on the outer toroid platform, several square cavities are equally spaced in described matrix, the upper surface of square cavity is open equipped with T-type, T-type opening is made of transverse opening and vertical openings, and transverse opening end is at central boss；Diamond segment bottom surface is connected with the link block that longitudinal section is " convex " font, and link block is caught in square cavity, and T-type opening is equipped with threaded hole, is equipped with screw in threaded hole and limits diamond segment.Diamond segment and matrix in the utility model are connected firmly, no matter all not easily to fall off in transporting or rotating.
Description
Technical field
The utility model relates to grinding tool field more particularly to a kind of diamond grinding knife tools.
Background technique
Diamond grinding knife tool in the prior art is the grinding class for being welded together to form diamond segment and matrix
Product when welding processing, needs the welding surface coated with flux in note trendy styles from Hong Kong cutter head and matrix, and silver soldering piece is added in high temperature and pressure
In the case of weld, the cost of raw material is high, and electric power energy consumption is big, and when replacement needs integral replacing, and replacement cost is big；In the prior art
Though having some technologies for replacing welding using connected structure, the split type structure cutter head of the prior art and the connection of matrix
It is insecure, it is easy to fall off.
Utility model content
The purpose of the utility model is to provide a kind of diamond grinding knife tools.
To realize above-mentioned purpose of utility model, the technical solution of the utility model is: a kind of diamond grinding knife tool, including
Matrix, matrix include the central boss and outer toroid platform of centre protrusion, and the center of central boss is equipped with installation
Hole is arranged in equal spacing with several diamond segments on the outer toroid platform, several rectangular skies is equally spaced in described matrix
The upper surface of chamber, square cavity is open equipped with T-type, and T-type opening is made of transverse opening and vertical openings, and transverse opening end is close
At central boss；Diamond segment bottom surface is connected with the link block that longitudinal section is " convex " font, and link block is caught in square cavity
Interior, T-type opening is equipped with threaded hole, is equipped with screw in threaded hole and limits diamond segment.
Diamond segment bottom surface is connected with the link block that longitudinal section is " convex " font, and link block is inserted into simultaneously from transverse opening
Vertical openings end is slid into, T-type opening is equipped with threaded hole, and screw screws in threaded hole and limits diamond segment after link block slides into
Position.It is all not easily to fall off when being connected firmly between matrix and diamond segment, either transport or work.
Further, the tangent line of the direction of the vertical openings and matrix direction of rotation is at an acute angle.In diamond grinding knife
When tool height rotates, diamond segment has the active force to principle the center point, just makes diamond segment to vertical openings
End it is mobile, when rotation, is less easy to fall off.
Further, the upper top surface of the link block is pierced equipped with several L-type teeth.So that the company of link block and diamond segment
It connects stronger.
Further, the diamond segment is water-drop-shaped cutter head, tip direction and the matrix rotation side of diamond segment
To consistent.Plane to be ground is cut at first with the tip of water-drop-shaped cutter head, can accelerate cutting speed, reduces moment resistance when incision
Power.
Further, several spiral canine tooth shape heat release holes are evenly equipped in the central boss.Diamond grinding knife tool rotation
When, the trend of spiral canine tooth shape heat release hole is consistent with the trend of wind, is more advantageous to heat dissipation.
Further, several through-holes are equipped in the square cavity.Conducive to scaling-off and heat dissipation.
The beneficial effects of the utility model are:
1, the diamond segment in the utility model and matrix are connected firmly, and no matter are all not easy to take off in transporting or rotating
It falls.
2, when having diamond segment damage in the utility model, damage cutter head is only needed to change, integral replacing is not necessarily to.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of matrix；
Fig. 3 is the structural schematic diagram of link block.
Specific embodiment
Below in conjunction with attached drawing, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of diamond grinding knife tool, including matrix 1, matrix 1 include central part
The central boss 2 and outer toroid platform 3 of position protrusion, the center of central boss 2 are equipped with mounting hole 11, on outer toroid platform 3
Several diamond segments 4 are arranged in equal spacing with, several square cavities 5, the upper surface of square cavity 5 are equally spaced on matrix 1
Equipped with T-type opening 6, T-type opening 6 is made of transverse opening 6.1 and vertical openings 6.2, and 6.1 end of transverse opening is close to central boss
At 2, the tangent line of 1 direction of rotation of direction and matrix of vertical openings 6.2 is at an acute angle；4 bottom surface of diamond segment is connected with vertical cut
Face is the link block 7 of " convex " font, and the upper top surface of link block 7 is equipped with several L-type teeth thorn 10, and link block 7 is caught in square cavity 5
It is interior, it is equipped with threaded hole at T-type opening 6, is equipped with screw 8 in threaded hole 9 and limits diamond segment 4.Link block 7 is from transverse opening
6.1 are inserted into and slide into 6.2 end of vertical openings, and screw 8 screws in threaded hole 9 and limits diamond segment 4 after link block 7 slides into.
Diamond segment 4 is water-drop-shaped cutter head, and the tip direction of diamond segment 4 is consistent with 1 direction of rotation of matrix, in central boss 2
Several spiral canine tooth shape heat release holes 13 are evenly equipped with, are equipped with several through-holes 12 in square cavity 5.
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this
Embodiment in utility model, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, fall within the protection scope of the utility model.
