Description
Technical field
The utility model relates to a kind of numerical control milling process equipment, particularly a kind of bent axle, the rough machined numerical control servo-actuated of camshaft crankshaft miling machine of being mainly used in.
Background technology
Along with the development of Numeric Control Technology in mechanical industry, the Milling Process efficiency of automobile, motorcycle bent axle, crank axle for vessel, I. C. engine crankshaft, engine crankshaft and camshaft etc. becomes the focal issue of bent axle processing industry, and plain-milling machine and manufacturing process can not satisfy the highly-efficient processing of this product fully; Carry out bent axle processing with crankshaft toothed wheel and common outer milling machine more than at present domestic, but process velocity is slow, precision is low; Complicated operation, the converted products difficulty of remodeling, and equipment investment is also bigger; Part developed country adopts powerful interior milling machine to carry out this processing, and its major defect is that equipment investment is huge, and production cost is high; The expense of remodeling height, flexible poor.Therefore, need be according to the actual conditions of state's inside crankshaft processing industry, a kind of more advanced numerical control of the utility model exploitation is with the dynamic crankshaft process equipment.
The utility model content
The purpose of the utility model is exactly the above-mentioned deficiency to prior art, and a kind of bent axle, the rough machined numerical control servo-actuated of camshaft crankshaft miling machine of being mainly used in is provided, and it is easy to operate, and process velocity is fast, and precision is high, and is flexible good.
The technical scheme of the utility model is achieved in that it comprises lathe bed and is installed in unit head on the lathe bed, centre frame, the headstock and tailstock; It is characterized in that: the cross power slide is installed on the lathe bed; Unit head has two, is positioned over lathe cross power slide top respectively in opposite directions, and each unit head all has a facing cutter that can change; The headstock and tailstock are arranged at lathe forward track two ends in opposite directions; Headstock spindle connects with the tailstock spindle Synchronous Transmission through synchronizing shaft, and connects with headstock servomotor through headstock transmission mechanism, and the two ends that headstock spindle and tailstock spindle are relative are provided with bent axle hydraulic pressure pallet.Between the headstock and tailstock, follow rest is housed.The headstock and tailstock are installed in the left side and the right side of bed ways; The headstock is connected the headstock and tail-stock hydraulic-pressure pallet with tailstock spindle through ring flange; The bent axle of processing is contained on the anchor clamps; The rotating tee of bent axle is crossed headstock servomotor and is driven the synchronizing shaft rotation, and synchronizing shaft is connected on the tailstock, and synchronizing shaft is transferred on the main shaft through backlash gear mechanism.
The operation principle of the utility model is: the processing of bent axle is transferred to main shaft through headstock servomotor backlash gear mechanism; Main shaft drives workpiece through the anchor clamps that connect and rotates; Unit head cutterhead on two cross slid platforms moves to corresponding two positions that machining crankshafts need be processed through the driven by servomotor transverse moving mechanism; The rotation of length feed and workpiece is done interlock and is followed milling; The processing at each position all is to be converted into procedure through digital control system according to calculated with mathematical model; Workpiece rotating shaft and unit head cutterhead length feed axle are done according to procedure and are followed Milling Process then, and centre frame drives centre frame mechanism through servomotor and axially moves, and centre frame is through bikini hydraulic pressure self-centering supporting workpiece; The strong point of workpiece is supported in the middle of the axle journal of two unit head cutterheads processing through program, has guaranteed the rigidity of bent axle and the flexural deformation of bent axle in the process.The processing of all sites all is to accomplish automatically through the nc program that weaves in advance, only need revise the processing that machined parameters just can be accomplished the different cultivars bent axle for different bent axle kinds.It is fast to the utlity model has process velocity, and precision is high, and is simple to operate, the converted products easy advantage of remodeling.
