Abstract
The utility model discloses a kind of resin dovetail groove split emery wheel, comprise metallic matrix (1) and resin wheel grinding block (2), the outer peripheral face of metallic matrix (1) has dovetail groove (3), the dovetail shaped projection (4) corresponding with the dovetail groove of metallic matrix (1) (3) is had in the bottom of resin wheel grinding block (2), the dovetail shaped projection (4) of resin wheel grinding block (2) embeds in the dovetail groove (3) of metallic matrix (1), is sintered to one with metallic matrix (1).The utility model adopts dovetail groove split-type structural, has saved material, has reduced use cost, had the features such as investment of production is little, cost is low, manufacture craft easily controls, percent defective is low, security is good.
Description
Technical field
The utility model relates to a kind of resin wheel, and particularly a kind of resin 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 be to provide a kind of investment of production little, produce and use cost is low, security is good resin dovetail groove split emery wheel, thus overcome 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 resin dovetail groove split emery wheel, its formation comprises metallic matrix and resin wheel grinding block, 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 resin wheel grinding block, the dovetail shaped projection of resin wheel grinding block embeds in the dovetail groove of metallic matrix, and is sintered to one with metallic matrix.
In above-mentioned dovetail groove split emery wheel, dovetail groove notch shape is outer little greatly interior.
In aforesaid dovetail groove split emery wheel, between adjacent resin 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 by metallic matrix and with metallic matrix be sintered to one resin wheel grinding block form, when resin wheel grinding block may wear to a certain degree, only need to change resin wheel grinding block, change easily, without the need to scrapping whole emery wheel, save material, improve emery wheel utilization rate, reduce use 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, resin wheel grinding block can be blocked, resin wheel grinding block is more firmly fixed, prevent resin wheel grinding block from coming off from metallic matrix in grinding process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side structure schematic diagram of the present utility model;
Fig. 3 is basal body structure schematic diagram of the present utility model;
Fig. 4 is resin wheel grinding block structural representation of the present utility model.
Detailed description of the invention
Embodiment 1.As Fig. 1, shown in 2, comprise metallic matrix 1 and the resin wheel grinding block 2 of annular, metallic matrix 1 can be the matrix of aluminium alloy or the metal material such as steel or titanium alloy, resin wheel grinding block 2 is resin material, the outer peripheral face of metallic matrix 1 has dovetail groove 3 (as shown in Figure 3), the dovetail shaped projection 4 (as shown in Figure 4) corresponding with the dovetail groove 3 of metallic matrix 1 is provided with in the bottom of resin wheel grinding block 2, for ensureing the connection reliability of resin wheel grinding block 2 and metallic matrix 1, the notch design of dovetail groove 2 is outer little greatly interior, resin wheel grinding block 2 is convenient to block.Gap 5 is also left, as the interval trough of emery wheel draining, cooling, chip removal between adjacent resin wheel grinding block 2.
During assembling, the dovetail shaped of resin wheel grinding block 2 protruding 4 is embedded in the dovetail groove 3 of metallic matrix 1, can resin wheel grinding block 2 be fixed on metallic matrix 1 by dovetail shaped protruding 4 with coordinating of dovetail groove 3, then by hot pressing sinter-hardened, resin wheel grinding block 2 and metallic matrix 1 can be connected as one, thus ensure that resin 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.
Claims (3)
1. a resin dovetail groove split emery wheel, comprise metallic matrix (1) and resin wheel grinding block (2), it is characterized in that: on the outer peripheral face of metallic matrix (1), have dovetail groove (3), the dovetail shaped projection (4) corresponding with the dovetail groove of metallic matrix (1) (3) is had in the bottom of resin wheel grinding block (2), the dovetail shaped projection (4) of resin wheel grinding block (2) embeds in the dovetail groove (3) of metallic matrix (1), is sintered to one with metallic matrix (1).
2. resin dovetail groove split emery wheel according to claim 1, is characterized in that: described dovetail groove (3) notch is outer little greatly interior.
3. resin dovetail groove split emery wheel according to claim 1, is characterized in that: between adjacent resin wheel grinding block (2), leave gap (5).
