Abstract

The utility model relates to a novel grinding disc type cubic boron nitride grinding wheel which can effectively solve the machining and grinding problems of high-speed steel components of air conditioners and refrigerator compressors. The utility model has the technical scheme that the center of a grinding disc type basal body is provided with a mounting hole, the basal body is provided with a fixed slot, the fixed slot and the mounting hole are concentric, a transverse screw hole is arranged on the edge part of the grinding disc type basal body, the lower part of the grinding disc type basal body is provided with a longitudinal screw hole and an aligning fixed hole, and a layer of cubic boron nitride is arranged on the grinding disc type basal body. The utility model has the advantages of simple structure, convenient use, long service life, high precision of processing components, level and low cost, and is a creative improvement for the existing grinding wheel; the utility model has wide development and application markets.

Description

Mill type cube boron nitride grinding wheel

One, technical field

The utility model relates to a kind of grinding tool, particularly a kind of mill type cube boron nitride grinding wheel.

Two, background technology

Raising along with people's life and economic condition, air-conditioning, refrigerator has entered huge numbers of families, and air-conditioning, the compressor part of refrigerator, as bent axle, roll sleeve, slide block, on, all exigent precision such as lower cover, the material that is adopted generally all is difficult grind materials such as high-speed steel, adopts carborundum, the grinding tool working (machining) efficiency that corundum is made is low, and finishing is frequent, coarse, be difficult to reach requirement, the compressor noise of production is big, and the life-span is short, the cost height, and imported equipments and parts and grinding tool price are high, and cost is higher, and difficulty is accepted economically, therefore, air-conditioning, the grinding tool that the refrigerator component processing is used remains to reform and improve.

Three, utility model content

At above-mentioned situation and actual needs, the purpose of the utility model just provides a kind of novel mill type cube boron nitride grinding wheel, can effectively solve air-conditioning, the processing grinding problem of freezer compressor high-speed steel parts, the technical scheme of its solution is, there is installing hole at abrasive disk type matrix center, with the concentric holddown groove that has of installing hole, in the portion of abrasive disk type matrix limit horizontal screw hole is arranged, screw hole and secured in alignment hole are longitudinally arranged at the bottom, the abrasive disk type substrates has cbn layer, and the utility model is simple in structure, and is easy to use, life-span is long, processing component precision height, smooth, cost is low, be to the existing creationary improvement of emery wheel, the wide development application market is arranged.

Four, description of drawings

Fig. 1 is a structural profile front view of the present utility model.

Fig. 2 is a upward view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Provide by Fig. 1, the utility model is that abrasive disk type matrix 1 center has installing hole 4, with the installing hole 4 concentric holddown grooves 5 that have, in the abrasive disk type matrix 1 limit portion horizontal screw hole 7 is arranged, screw hole 2 and secured in alignment hole 3 are longitudinally arranged at the bottom, and cbn layer 6 is arranged above the abrasive disk type matrix 1.

Abrasive disk type matrix 1 is the round metal disk body, mill is two mills when using, so also claim two mill cubic boron nitride abrasive wheels, cubic boron nitride is a CBN material alleged on the market, cbn layer 6 can stick on above the metallic matrix with commercially available two-in-one binding agent, also but sintering is on metallic matrix, and its attached form is selected as required, and the matrix size optionally can be made into series of products.

By said structure as can be seen, the utility model is because in use, adopt a plurality of screw holes to be fixedly connected through screw and lathe, be ground part and place (the two mills of title again) between two dishes, up and down to mill, steady and firm, and adopt the very excellent cubic boron nitride of performance to be bonded in metallic object as on the ring flange (abrasive disk type) as abrasive material, since cubic boron nitride (CBN) not with iron family element generation chemical reaction, therefore, can not only be competent at the processing of difficult grind material, enhance productivity, help the shape and size precision of strict control workpiece, and can also improve the grinding quality of workpiece, significantly improve the surface integrity of mill back workpiece, improve the fatigue strength of part, increase the service life, increase reliability, add that the cubic boron nitride abrasive materials production process producing well than conventional abrasive material aspect energy resource consumption and the environmental pollution, the production of cubic boron nitride grinding tool and application are the trends of the times of development of machinery industry.Of the present utility model succeeding in developing is to having big substitute products of diamond abrasive tool now, huge economic and social benefit being arranged.

Claims

1, a kind of mill type cube boron nitride grinding wheel, it is characterized in that, there is installing hole (4) at abrasive disk type matrix (1) center, with the concentric holddown groove (5) that has of installing hole (4), in abrasive disk type matrix (1) the limit portion horizontal screw hole (7) is arranged, screw hole (2) and secured in alignment hole (3) are longitudinally arranged at the bottom, and cbn layer (6) is arranged above the abrasive disk type matrix (1).

2, mill type cube boron nitride grinding wheel according to claim 1 is characterized in that, said abrasive disk type matrix (1) is the round metal disk body.
