Abstract
The invention relates to a grinding wheel correcting device of an engine crankshaft cylindrical grinding machine. The grinding wheel correcting device of the engine crankshaft cylindrical grinding machine comprises a fixed seat and a correcting grinding apparatus, wherein the correcting grinding apparatus is fixedly connected with the fixed seat and comprises a diamond pen and a chamfer correcting block; the diamond pen is fixedly connected with the chamfer correcting block through a diamond pen fixing seat; the chamfer correcting block is U-shaped; and a first circular bead grinding head and a second circular bead grinding head are respectively arranged at two ends of the chamfer correcting block and are symmetric to each other. The grinding wheel correcting device of the engine crankshaft cylindrical grinding machine has the advantages that a grinding wheel of the crankshaft grinding machine can be corrected at one step, and the grinding wheel correcting device is convenient to use and simple in structure.
Description
Technical field
The present invention relates to instrument, be specifically related to a kind of correcting device for the emery wheel in engine crankshaft cylindrical grinder.
Background technology
Nowadays, the manufacturing industry of automobile is as soaring in day.Wherein, engine crankshaft is the very large auto parts and components of a kind of demand.Its machining accuracy is related to the overall maneuvering performance of automobile.The automobilism vibration of using the high engine crankshaft of dimensional accuracy to be assembled is little, long service life.The automobile using the coarse engine crankshaft of dimensional accuracy to assemble out, can cause engine resonate under steam, the harm of resonance be one side serious reduce comfort level.What accelerate automobile engine on the other hand scraps speed.
Therefore should start with from the production technology of bent axle and be improved the production precision of bent axle by the precision improving grinder wheel, application number 200920071098.4 patent provides a kind of grinding wheel angle dresser for grinding, this corrector, by right adjustment moving slide board and left adjustment moving slide board adjustment chamfering parameter, implements disposable correction.Its structure is simple, easy to operate.Due to the emery wheel refined bent axle cylindrical, concentrate to reduce stress, emery wheel adopts rounding.The radius size of rounding adopts 3 ~ 5mm.Therefore need to provide a kind of correcting device for crankshaft grinding machine on above-mentioned disclosed prior art basis.
Summary of the invention
The deficiency of integrated background technology of the present invention, provides a kind of wheel truing device, and this correcting device implements disposable correction for the emery wheel of the grinding machine used in Crankshaft Machining.
Technical scheme of the present invention is as follows: the wheel truing device of engine crankshaft cylindrical grinder, comprise holder, revise grinding tool, described correction grinding tool is fixedly connected with described holder, described correction grinding tool comprises diamond pen, chamfering correction block, and described diamond pen is fixedly connected with described chamfering correction block by diamond pen holder; Described chamfering correction block is U-shaped, and the two ends of described chamfering correction block are respectively equipped with the first fillet bistrique, the second fillet bistrique, described first fillet bistrique and described second fillet bistrique symmetrical.
Further, the nib of described diamond pen and described first fillet bistrique and described second fillet bistrique are in same straight line.
Further, described holder is provided with fixing hole, and the number of described fixing hole is 2 ~ 4.
Further, the cutting anterior angle of described first fillet bistrique, the second fillet bistrique is 2 ~ 8 °, and tool point angle is 65 ~ 80 °.Wherein said cutting anterior angle is described first fillet bistrique, the upper surface of the second fillet bistrique and the angle of horizontal plane, and wherein tool point angle its value in above-mentioned scope is larger, and the load that bistrique bears is larger, and cutting effect is undesirable.In above-mentioned scope, its value is less, and the load that bistrique bears is less, and cutting effect is fine.Cut the surface quality that soft material feeding ensures to cut, the tool point angle that should select should be less.The appropriate to the occasion tool point angle selected of the material that cutting hardness hardness is larger should be larger.
Further, the cutting anterior angle of described first fillet bistrique, the second fillet bistrique is 5 °, and tool point angle is 75 °.
Beneficial effect of the present invention is: the nib of described diamond pen and described first fillet bistrique and described second fillet bistrique are located along the same line, first by radial feed emery wheel, the nib of described diamond pen is contacted with the cylindrical of emery wheel, then pass through both direction axial feed emery wheel successively to the cylindrical of emery wheel and the enforcement correction of rounding, above-mentioned makeover process is disposable to be completed.Therefore correcting device of the present invention carries out disposable correction for the emery wheel of crankshaft grinding machine, and easy to use, structure is simple.
