Description
Technical field
The utility model belongs to superhard material abrasive tool industry, refers specifically to a kind of crankshaft journal processing electroplating CBN emery wheel.
Background technology
The necked part of automobile engine crankshaft is typically ground using special electroplating CBN (cubic boron nitride) emery wheel
Processing, in process simultaneously, axle journal end face cylindrical to axle journal and undercut groove this be ground at three.Existing this kind of emery wheel exists
It is not satisfactory to the processing effect of crankshaft journal, axle journal end face burn is easily caused, when this aspect is due to grinding axle journal end face
Cutting fluid is not easily accessible, thus can not fully participate in cooling；On the other hand, the processing conditions needed for axle journal end face is different from axle journal
Cylindrical and undercut groove is, it is necessary to which emery wheel corresponding function region has higher grinding efficiency.It is therefore desirable to this kind of emery wheel is carried out
Targetedly transform, so as to improve the crudy of automobile engine crankshaft.
The content of the invention
The utility model is for problems of the prior art to the electroplating CBN sand for grinding at crankshaft journal
Wheel is transformed, to prevent axle journal from end face burn occurring in process.
Crankshaft journal processing electroplating CBN emery wheel described in the utility model includes discoid metallic matrix, fine grained and ground
Cut layer and coarse granule grinding layer.Two circle arc convex, metallic matrix are arranged with periphery at the metallic matrix exterior angle
The ring-shaped platform of two evaginations is arranged with side at exterior angle, the ring-shaped platform is merged with arc convex in edge,
Surface smoothly transits, and the top planes of ring-shaped platform are function side, and medial surface is a drain inclined-plane extended obliquely downward, two
Metallic matrix periphery between arc convex is function end face.Fine grained is attached with the arc convex surface and function end face
Coarse granule grinding layer is attached with grinding layer, function side.
Preferably, the angle of the function side and drain inclined-plane is 8~12 °.
Preferably, the width of the function side is 0.5~1.5mm.
The fine grained grinding layer uses B213 abrasive materials, and coarse granule grinding layer uses B251 abrasive materials.
Crankshaft journal processing described in the utility model can preferably meet adding for axle journal different parts with electroplating CBN emery wheel
Work requirement, effectively prevents axle journal from end face burn occurring in process, while improving the crudy of bent axle and making for emery wheel
Use the life-span.

Embodiment
To make the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this practicality
The new crankshaft journal processing is described further with electroplating CBN emery wheel.
As shown in Figure 1, 2, crankshaft journal processing described in the utility model includes discoid Metal Substrate with electroplating CBN emery wheel
Body 1, fine grained grinding layer 2 and coarse granule grinding layer 3.Two circle arcs are arranged with periphery at the exterior angle of metallic matrix 1 convex
Play the ring-shaped platform 12 that two evaginations are arranged with the side at 11, the exterior angle of metallic matrix 1, ring-shaped platform 12 and arc convex
11 smoothly transit on edge fusion, surface, and the top planes of ring-shaped platform 12 are function side 13, and medial surface is tilted towards for one
The periphery of metallic matrix 1 between the drain inclined-plane 14 of lower extension, two arc convex 11 is function end face 15.The surface of arc convex 11
And it is attached with fine grained grinding layer 2 on function end face 15, it is attached with coarse granule grinding layer 3 on function side 13.
Function end face 15, arc convex 11 and function side 13 in above-mentioned electroplating CBN emery wheel correspond respectively to Crankshaft
The axle journal of neck is cylindrical, undercut groove and axle journal end face, and it is higher targetedly on function side 13 to be provided with grinding efficiency
Coarse granule grinding layer 3, compared to fine grained grinding layer 2, the abrasive grain of this layer is bigger, and more sharp, grain spacing is also larger,
The heat that helps to reduce and produce during scattered grinding simultaneously takes abrasive dust out of, prevents axle journal end from burning, it is ensured that Crankshaft
Crudy at neck.
On the other hand, drain inclined-plane 14 is set to help cutting fluid importing the gap of emery wheel and axle journal end face and take away portion
Divide grinding heat, the probability that further reduction axle journal end is burnt.
Electroplating CBN emery wheel is completely covered for assurance function side 13 by coarse granule grinding layer 3 in the fabrication process, coarse granule
Grinding layer 3 is actually also possible to expand on drain inclined-plane 14, partial or complete covering drain inclined-plane 14, and this will not affect that emery wheel
Basic function, be attached with coarse granule grinding layer 3 on function side 13 and whole drain inclined-plane 14 in embodiment.
The angle of function side 13 and drain inclined-plane 14, i.e., the included angle B indicated in figure is 8~12 °.
The width of function side 13 is 0.5~1.5mm, it is ensured that the grinding efficiency of axle journal end face and the use longevity of emery wheel
Life.
Fine grained grinding layer 2 uses B213 abrasive materials, and coarse granule grinding layer 3 uses B251 abrasive materials, both abrasive materials of selection
The processing request of different parts on crankshaft journal can preferably be met, it is ensured that crudy, and be favorably improved making for emery wheel
Use the life-span.
