Description
Technical field
The utility model relates to a kind of motorcycle component clamp for machining, is specifically related to a kind of crankshaft of motorcycle boring grab.
Background technology
Crankshaft of motorcycle is one of most important parts in motorcycle engine, and its function is gathered at the reciprocating motion of each for engine cylinder piston, and pass to flywheel with the form of gyration, then externally exports acting.Due to the shape of bent axle and stressed very complicated, and critical role within the engine in structure, therefore it is very high to manufacture requirements, is one of parts that engine cost is the highest.
Crankshaft of motorcycle comprises trunnion, secondary axle journal, crankpin and bent axle, and support the part of crankshaft rotating trunnion, trunnion is provided with bearing, and the outer surface of secondary axle journal is provided with spline.Rightly carry out design optimization for bent axle, usually adopt the mode alleviating crankshaft quality to carry out.But the change of crankshaft quality can cause the change of center of gravity, the main inclination angle of mass centre changing rear crank linkage also can change, and main inclination angle can have influence on the change of motorcycle vibration.Obtain optimum main tilt angles by finite element method analysis, thus extrapolate the optimum position of centre of gravity of bent axle, then realize the bent axle position of centre of gravity in calculating by machining bent axle.Common processing method is holed exactly on bent axle, first bent axle will be fixed, more radially holes from the side of bent axle.In order to change bent axle position of centre of gravity, usually need to bore multiple hole, and then need the angle of change bent axle and fixed, operation is comparatively complicated, and each fixing all needs to correct bent axle, adds the work load of operator, reduces working (machining) efficiency.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of simple to operate, reduce operator's work load, improve the motorcycle crank shaft drilling clamp of working (machining) efficiency.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of crankshaft of motorcycle boring grab, it is characterized in that: comprise base plate, the upper surface of described base plate is linearly arranged in sequence with supporting plate I, supporting plate II and fixed head and be connected with described base plate is detachable respectively, the upper end of described supporting plate I and supporting plate II is detachable is separately connected with clamp I and clamp II, the bearing clamping hole I for fixing bent axle upper bearing (metal) to be held is offered between described supporting plate I and described clamp I, the bearing clamping hole II for fixing bent axle upper bearing (metal) to be held is offered between described supporting plate II and described clamp II, described fixed head offers splined hole, described bearing clamping hole I, described bearing clamping hole II and described splined hole are coaxially set.
In the utility model, during use, first open clamp I and clamp II, again the splined end on crankshaft of motorcycle is inserted in the splined hole on fixed head, in simultaneously make the bearing on the trunnion of crankshaft two end be placed on respectively part that bearing clamping hole I is positioned at supporting plate I and bearing clamping hole II be positioned in the part of supporting plate II, finally clamp I and clamp II are connected and fixed with supporting plate I and supporting plate II respectively, bearing clamping hole I part on clamp I and the II pair of bearing of the bearing clamping hole on clamp II are fixed.After splined hole on fixed head and the spline fitted on bent axle, bent axle cannot be rotated again, and then whole bent axle is fixed, with processing hole to be drilled.The angle of different splined holes can be set on fixed head according to the anglec of rotation that bent axle is different, bent axle just can be made to fix by means of only the different fixed head of replacing, whole Drilling operation is operated simpler, also eliminate each work corrected simultaneously, reduce operator's work load, improve working (machining) efficiency.
As optimization, the inwall of described bearing clamping hole I is equipped with the annular receiving groove I arranged around described bearing clamping hole I axis, the inwall of described bearing clamping hole II is equipped with the annular receiving groove II arranged around described bearing clamping hole II axis.Two bearings on bent axle are placed in annular receiving groove I and annular receiving groove II respectively, carry out spacing by groove to bearing, are conveniently fixed bearing.
As optimization, the bottom land of described annular receiving groove I and described annular receiving groove II is equipped with resilient rubbber cushion respectively.Utilize resilient rubbber cushion as the buffering between bearing and annular receiving groove, avoid making to cause damage to bearing to rigid contact between the two.
As optimization, described fixed head line centered by the axis of described bearing clamping hole I and described bearing clamping hole II offers through hole, bearing is embedded with in described through hole, spill spin block is embedded with in the inner ring of described bearing, described splined hole to be positioned on described spill spin block and towards described supporting plate II direction, described plate upper surface is also provided with servomotor, described servomotor is positioned at described fixed head away from the side of described supporting plate II and is connected with described base plate is detachable, the axis of the output rotation axis of described servomotor and the inner ring center line of described bearing are coaxially set, the output rotation axis of described servomotor is fixedly connected with described spill spin block.Bent axle fixes and after processing a hole, starts servomotor, and the output rotation axis driven rotary block of servomotor rotates, and then changes the anglec of rotation of bent axle.After rotating to certain angle, close servomotor, servomotor cannot be rotated further when self-locking again, and then also makes bent axle to be rotated further again, then carries out processing boring.Controlled the rotation of bent axle by servomotor, not only rotational angle is accurate, also eliminates the time changing fixture, further increases operating efficiency.
In sum, the beneficial effects of the utility model are: the utility model structure is simple, utilize fixture to change the rotational angle of bent axle and to be fixed, whole Drilling operation is operated simpler, also eliminate each work corrected simultaneously, reduce operator's work load, improve working (machining) efficiency.
