Description
Technical field
The utility model relates to a kind of high accuracy circular cylindrical parts outer round surface precision processing technology field, particularly relates to a kind of cylindrical component outer round surface milling apparatus and method thereof.
Background technology
Cylinder roller bearing is widely used in all kinds of rotating machinery.As the cylindrical roller of cylinder roller bearing strength member, the processing precision direct influence of its outer round surface the performance of cylinder roller bearing.The precision machined main method of cylindrical component outer round surface has microstoning and the planetary Ginding process of double plate.
Microstoning is that one utilizes microstone as grinding tool, and oilstone is to workpiece imposed load and opposite piece does low speed axially-movable and of reciprocating vibration a little, thus realizes the polishing processing method of micro cutting.At present, penetration type superfine processing method is not in the mood in the many employings of Precision Machining of cylindrical roller outer round surface, its equipment is become with a superfinishing head group that oilstone is housed by two deflector rolls, guide rolls support workpiece also drives workpiece to do slow spin motion, oilstone is pressed to workpiece with lower pressure by superfinishing head, between oilstone with workpiece, forming surface contacts, and oilstone does dither simultaneously vertically.Be not in the mood in penetration type superfinishing process, the cylindrical roller of same batch runs through machining area successively and stands Oilstone super-finishing processing, after all cylindrical rollers are all by machining area several times, certain one microstoning operation (extra coarse, carefully super, essence surpass) terminates.Be not in the mood for penetration type microstoning and can improve workpiece surface roughness (penetration type microstoning can reach Ra0.025 μm usually), remove the damaged surface layer that last process is formed, improve Roundness of Workpiece.Except oilstone and the change of superfinishing roller state of wear and self difference of each cylindrical roller, it is identical with parameter that each cylindrical roller stands superlinishing condition.
But by the restriction of process principle, microstoning exists following technological deficiency: on the one hand, in process, the change of oilstone and deflector roll state of wear is unfavorable to the dimensional accuracy and form accuracy that improve cylindrical roller periphery; On the other hand, limited several cylindrical rollers are only had to stand processing owing to not being in the mood for penetration type superfine processing method synchronization, its material removal amount by itself and the impact with batch other cylindrical roller diameter phase mutual deviations, is not therefore in the mood for penetration type microstoning and obviously can not be reduced cylindrical roller diameter phase mutual deviation hardly.Above-mentioned two aspects cause machining accuracy (form accuracy and the dimensional uniformity) Slow lifting on excircle of workpiece surface, and the process-cycle is long, cost is high.
The primary structure of double plate planetary cylindrical component milling apparatus comprises top lap, lower abrasive disk, planetary gear retainer, external toothing and ring gear.Top lap and lower abrasive disk coaxially arranged, independently rotate, above fold pressurization, planetary gear retainer is placed between ring gear and external toothing, and cylindrical roller is placed in the hole slot of retainer, and hole slot distributes radially on retainer surface.During grinding, retainer around abrasive disk center revolution simultaneously rotation, cylindrical roller under the effect of upper and lower abrasive disk and retainer not only around the revolution of retainer center simultaneously but also around own axes rotation, do complex space motion.Between upper and lower abrasive disk lapping liquid effect under realize micro-removal of material.Double plate planetary cylindrical component milling apparatus can obtain high-precision cylindrical workpiece outer round surface, such as, for the workpiece of length 30 ~ 40mm, after utilizing two-lap lapping machine Precision Machining, can reach deviation from circular from be less than 0.001mm, longitudinal section diameter uniformity is less than 0.002mm, surface roughness is less than Ra0.025 μm.But two-lap lapping machine can only be used for the cylindrical Precision Machining of small lot (tens to hundreds of) cylindrical work.For the demand in enormous quantities of bearing roller, the planetary Ginding process of double plate is difficult to be competent at.
As can be seen here, employing is not in the mood for penetration type superfine processing method and is carried out Precision Machining to excircle of cylindrical workpiece surface, natural deficiency is there is in machining accuracy, and the planetary Ginding process of double plate can not meet requirements of mass production, so be badly in need of a kind of cylindrical component outer round surface precise machining equipment that can realize compared with high manufacturing accuracy and production in enormous quantities, to meet high accuracy cylinder roller bearing to the machining accuracy of cylindrical roller outer round surface and manufacturing specification request.
