Abstract
The utility model relates to a special miller which is used for machining a crankshaft and particularly a main journal and a crank journal of the crankshaft. The utility model is characterized in that spindles on a head frame and a tail frame are all connected with a synchronizing shaft through gear engagement. The transmission ratio between the head frame and the synchronous shaft is equal to the transmission ratio between the tail frame and the synchronous shaft, so that the spindles on the head frame and the tail frame are synchronously driven and the processed shaft center can rotate synchronously with the spindles shaft centers for the head frame and the tail frame under clamping of a special clamping tool to ensure smooth processing of a milling cutter. The utility model has the advantages of high precision of machining, reduced procedures of crankshaft machining, increased speed of machining, simple structure, low production cost and convenient maintenance.
Description
The utility model be a kind of machining crankshafts that is used for, particularly machining crankshafts trunnion, turn the production miller of axle journal.
The method of existing machining crankshafts, be to pass through lathe to trunnion with casting or forge the crank shaft blank that comes out, turn after axle journal carries out roughing, entering common crankshaft grinding machine roughly grinds and half correct grinding, and then on the high accuracy crankshaft grinding machine, finish grind, the method operation is many, consuming time, power consumption and substandard products are many, existing milling machine, machining accuracy and speed are better than engine lathe, but the characteristics of milling machine are the milling cutter action, and workpiece is motionless or only carry out horizontal, lengthwise movement can not be used for the processing of the workpiece of this complexity of bent axle.Existing a kind of bent axle special purpose lathe, its process velocity is very fast, but cost is too high, costs an arm and a leg, and domestic manufacturer is difficult to use.
Goal of the invention of the present utility model will provide a kind of machining accuracy height exactly, and the time is short, little power consumption, and the yield rate height, and also price is low, the production miller of machining crankshafts easy to maintenance.
Goal of the invention of the present utility model is achieved in that the production miller that is used for machining crankshafts, by the headstock, tailstock, lathe bed, the milling cutter unit head is formed, a synchronizing shaft is connected with belt pulley by the two-stage worm and gear, it is characterized in that synchronizing shaft and headstock spindle, at least a gear pair of one-level all is installed between the tailstock spindle, and the gearratio of two gear pairs equates, owing to used the headstock, the mode of tailstock Synchronous Transmission, make headstock spindle, tailstock spindle just can reach the purpose of synchronous rotation, by headstock main shaft, the bent axle of the special fixture clamping on the tailstock spindle also just can all permanently be transferred impassive distortion, thereby guaranteed the trunnion on the bent axle or turned center line and the headstock spindle of axle, the tailstock spindle center line is consistent and is rotated, and just can make milling cutter successfully finish trunnion or turns the outer garden of axle journal and the processing of end face.
Adopt the utility model that bent axle is processed, its process velocity is fast, and precision is higher, and the bent axle after the processing can directly carry out half correct grinding or correct grinding, not only improves work efficiency, economize on electricity, yield rate height.And manufacturing process of the present utility model is simple, and cost only reaches 1/4th of bent axle special purpose lathe, and is cheap, is convenient to promote the use of in China Production of Crankshaft producer.
Accompanying drawing 1 is a front schematic view of the present utility model.
Accompanying drawing 2 is the generalized section of the utility model headstock, tailstock.
In Fig. 1, be fixed with the headstock 1, tailstock 2, milling cutter unit head 4 on the lathe bed 10.Be fixed with driving motor 5, headstock spindle ring flange 6 on the headstock 1, headstock anchor clamps 8.The tailstock ring flange of fixing on the tailstock 27, tailstock anchor clamps 9.The headstock 1 all is connected with synchronizing shaft 3 with tailstock 2.Milling cutter 11 is installed on the milling cutter unit head 4.
In the accompanying drawing 2, belt pulley 12 is connected with motor 5 by belt.Worm screw 21 on the belt pulley 12 is meshed with worm gear 13, co-axially fixed worm screw 23 is meshed with worm gear 14 on the worm gear 13, and worm gear 14 is fixed on the end face clutch 15, reaches on the synchronizing shaft 3 by end face clutch 15, be fixed with headstock travelling gear 16 on the synchronizing shaft 3, tailstock travelling gear 17.Headstock travelling gear 16 all is meshed with headstock idle wheel 24 with spindle transmission gear 27 on being fixed on headstock spindle 20, constitutes a secondary gear pair.Tailstock travelling gear 17 all is meshed with tailstock idle wheel 26 with spindle transmission gear 28 on being fixed on tailstock spindle 25, constitutes a secondary gear pair, and the gearratio of two secondary gear pairs equates.An end face clutch 15 is installed on synchronizing shaft 3, can makes the headstock, tailstock, synchronizing shaft rear end stop transmission.Eccentric shaft 18 and eccentric shaft 25 are the gaps that are used to eliminate between the secondary gear pinion.Synchronizing shaft 3 and headstock spindle 20, the form of also available one-level gear pair connects between the tailstock spindle 19, be 16 direct and headstock spindle travelling gear 27 engagements of headstock travelling gear, 17 direct and tailstock spindle travelling gear 28 engagements of tailstock travelling gear, the rotation direction of changing motor 5 gets final product.The form of also available multi-stage gear pair connects.
From accompanying drawing, driving belt pulley 12 by motor 5 rotates, transmission by the two-stage worm and gear, just can make synchronizing shaft 3 carry out the rotation of big reduction of speed, (the also kind of drive of available decelerator), transmission at the gear pair that equates by two gearratios on the headstock 1, the tailstock 2 under the transmission of synchronizing shaft 3, headstock spindle 20 and tailstock spindle 19 are rotated synchronously, the bent axle that also just can guarantee to be clipped on headstock anchor clamps 8, the tailstock anchor clamps 19 carries out all permanent the rotation, processes to guarantee milling cutter 11 with being well on.
Will change according to the bent axle of different model and processed different parts the milling cutter on the milling cutter unit head 4 among Fig. 1 and the distance between the milling cutter and special fixture, the milling cutter unit head 4 in the accompanying drawing 1 is used for outer garden of machining crankshafts trunnion and end face.
