Description
Technical field
The utility model relates to a kind of dovetail groove split emery wheel, belongs to grinding tool technical field.
Background technology
At present, the emery wheel mainly monolithic construction of use, namely emery wheel entirety is all be made up of abrasive material, this Integral sand foot wheel abrasion just can not continue to use to a certain extent, remaining emery wheel can only be abandoned, need to change whole emery wheel, cause waste of material, utilization rate is low, increases use cost.And when high-speed grinding, easy stressed breakage, dangerous.In manufacturing process, because mold pressing is uneven, sinter the reasons such as wayward, the emery wheel quality of making differs, and percent defective is high.The emery wheel that diameter is larger is like this, the problems such as such as more than the emery wheel of 500mm, and monoblock type emery wheel also needs the input of large scale production equipment, there is investment of production large, and production cost is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dovetail groove split emery wheel, and its investment of production is little, produce and use cost low, security is good, thus overcomes the deficiency of existing monoblock type emery wheel.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of dovetail groove split emery wheel, it forms the metallic matrix comprising annular and the wheel grinding layer be fixed on metallic matrix outer peripheral face, described wheel grinding layer is combined by least two pieces of wheel grinding blocks, the outer peripheral face of metallic matrix there is dovetail groove, there is the dovetail shaped corresponding with the dovetail groove of metallic matrix protruding in the bottom of wheel grinding block, the dovetail shaped projection of wheel grinding block embeds in the dovetail groove of metallic matrix, is fixed on metallic matrix by wheel grinding block; Chimeric place that is protruding at dovetail shaped and dovetail groove leaves gap.
In above-mentioned dovetail groove split emery wheel, dovetail shaped is protruding is sintering integrated shaping with wheel grinding block, and the sidewall of dovetail shaped projection and the included angle A of bottom are 30 ~ 60 degree; Be preferably 45 degree.
In aforesaid dovetail groove split emery wheel, dovetail groove notch shape is outer little greatly interior.
In aforesaid dovetail groove split emery wheel, between adjacent wheel grinding block, leave gap.
The beneficial effects of the utility model: compared with prior art, the utility model adopts split-type structural, emery wheel is made up of metallic matrix and the wheel grinding layer be fixed in metallic matrix outer rim, when grinding layer may wear to a certain degree, only need to change grinding layer, change easily, without the need to changing whole emery wheel, save material, improve emery wheel utilization rate, reduce use cost.And due to wheel grinding layer be spliced by polylith wheel grinding block, the volume of wheel grinding block is little, without the need to using large scale production equipment, investment of production is little, cost is low, and manufacture craft more easily controls, and percent defective is low, other wheel grinding block individual is the quality that waste product can not affect other wheel grinding blocks, reduces production cost.Its matrix adopts the metallic matrix such as aluminium alloy or titanium alloy, can not burst, have higher use linear velocity.And dovetail groove notch on matrix is outer little greatly interior, by the shape of dovetail groove, wheel grinding block can be blocked, wheel grinding block is more firmly fixed, prevent wheel grinding block from coming off from matrix in grinding process, the utility model is protruding at dovetail shaped leaves gap with chimeric place of dovetail groove, can filled thermoset resin in this gap, sinter-hardened by hot pressing, guarantee that wheel grinding block does not drop, security is good.

Detailed description of the invention
Embodiment 1.As shown in Figure 1,3, the metallic matrix 1 comprising annular and the wheel grinding layer be fixed on metallic matrix 1 outer peripheral face, wheel grinding layer is spliced by polylith wheel grinding block 2.Metallic matrix 1 can be the matrix of aluminium alloy or the metal material such as steel or titanium alloy, the outer peripheral face of metallic matrix 1 has dovetail groove 3 (as shown in Figure 4), the dovetail shaped projection 4 (as shown in Figure 5) corresponding with the dovetail groove 3 of metallic matrix 1 is provided with in the bottom of wheel grinding block 2, for ensureing the connection reliability of wheel grinding block 2 and metallic matrix 1, the notch design of dovetail groove 2 is outer little greatly interior, the sidewall of dovetail shaped projection 4 and the included angle A of bottom are designed to 30 ~ 60 degree, wheel grinding block 2 is convenient to block, the sidewall of dovetail shaped projection 4 and the included angle A of bottom are preferably 45 degree, not only connection reliability can be ensured, also can take into account processing cost and working (machining) efficiency.Dovetail shaped protruding 4 and wheel grinding block 2 be adopt sintering integrated shaping, more firm than bonding.Gap 6 is also left, as the interval trough of emery wheel draining, cooling, chip removal between adjacent wheel grinding block 2.During assembling, the dovetail shaped of wheel grinding block 2 protruding 4 is embedded in the dovetail groove 3 of metallic matrix 1, can wheel grinding block 2 be fixed on metallic matrix 1 by dovetail shaped protruding 4 with coordinating of dovetail groove 3, gap 5 (as shown in Figure 2) is left with chimeric place of dovetail groove 3 at dovetail shaped protruding 4, filled thermoset resin in this gap 5, sinter-hardened by hot pressing, can ensure that wheel grinding block 2 does not drop.Structure of the present utility model is particularly suitable at the large grinding of 500-2000mm for matrix radius, can greatly reduce costs, and improves wheel grinding effect.For the emery wheel that width is larger, multiple row combining structure as shown in Figure 6 can be adopted.
