Description
Technical field
This utility model relates to Production of Crankshaft apparatus field, more specifically, it relates to a kind of crankshaft grinder structure。
Background technology
Bent axle is most important parts in electromotor。It bears the power that connecting rod transmits, and is transformed into torque and is exported by bent axle and drive other adnexaes work on electromotor。Bent axle is subject to the combined effect of the centrifugal force of gyrating mass, the gas inertia power of mechanical periodicity and reciprocal inertia force, makes bent axle bear the effect of flexion torsion load。Therefore it is required that bent axle has enough strength and stiffness, journal surface need are wear-resisting, work is uniform, balance is good。
Crankshaft processing technology flow process has: 1, blank is made an inventory, 2, end face milling, 3, milling two head mass center hole, 4, clamping face, milling location, 5, rough turn axle journal and termination connecting rod neck, 6, bore oil hole, 7, make an inventory oilhole two face, 8, finish turning axle journal nine, finish turning end face, 10, finish turning 1, 4 connecting rods, 11, finish turning 2, 3 connecting rods, 12, rolling, 13, fine grinding cone pulley, gear and Front oil seal axle journal, 14, finish turning thrust surface, end face of flange and locating journal, 15, fine grinding trunnion and Rear oil seal axle journal, 16, fine grinding rod journal, 17, keyseat, 18, oil hole orifice chamfer, 19, wash, 20, oilhole mouth throws mouth, 21, dynamic equilibrium, 22, subtract the balanced duplicate removal of outer supplement, 23, clearance keyway and oil hole, 24, polishing, 25, clearance, 26, inspection eventually, 27, antirust。
At present, the application number on market be 201310748365.8 Chinese patent disclose the trunnion grinding lathe of a kind of bent axle, it includes clamp system and grinding mechanism；The trunnion grinding lathe of bent axle, including clamp system and grinding mechanism, directly placing on lathe by bent axle, taper thimble one and taper thimble two insert in the cone shaped countersink of crankshaft two end, bent axle clamped by two pieces of fixture blocks, adopts driving lever to stir the trunnion of bent axle spin finishing bent axle。
During grinding, advance in tractive driven by motor sand ribbon, sand ribbon, driven by motor mounting seat slidably reciprocates along slide rail, realize the sand ribbon trunnion to bent axle to grind, when grinding bent axle, directly bent axle is placed in positioning pillars one and positioning pillars two, taper thimble one and taper thimble two insert the cone shaped countersink of crankshaft two end and are accommodated by bent axle, need the bent axle that the existing bent axle clamping technique of staff causes that catcher mark easily easily occurs although avoiding, avoid follow-up grinding and accommodate impression, however it is necessary that grinding mechanism drives sand ribbon friction bent axle, therefore this structure there is problems in that 1, the structure of grinding mechanism is complicated, therefore use and keep in repair this grinding mechanism costly, it is unfavorable for being widely popularized use；2, owing to bent axle does not rotate, therefore the fit dimension of clamping fixed block being required height, not so clamping fixed block is tight or loose when clasping, and bent axle all can be caused to have part surface to be ground to, and therefore crankshaft surface contacts uneven with sand ribbon, affects Grinding Quality；If 3, grinding mechanism only one of which, then bent axle once can only grind and turn footpath when grinding, and length consuming time is ground in the multiple footpath of turning of bent axle, and working (machining) efficiency is low；And if lathe is configured with multiple grinding mechanism when bent axle being ground simultaneously, although being conducive to improving work efficiency, but configuration structure is many, only tractive motor in sand ribbon is accomplished by multiple stage, considerably increases use cost, is unfavorable for being widely popularized。
