Description
Technical field
The invention belongs to Technology for Turning Machining, specifically is a kind of bearing ring turning tool feeding method.
Background technology
Bearing ring is adding man-hour, needs structures such as turning raceway groove, chamfering, seal groove.Existing bearing ring Vehicle Processing equipment adopts hydraulic-driven more; In use exist because the oil temperature changes the fluctuation that causes the apparatus settings cutting parameter, simultaneously, cutting parameter is transferred difficulty during owing to hydraulic-driven; Can only realize primary feed processing; Internal stress is big, thereby influences the machining accuracy and the form accuracy of product: 1. bearing ring automatic turning production line in the process of turning converted products, the setting of planker feeding parameters; Can directly have influence on product quality like rotating speed, feed speed, withdrawing delay time, the whether smooth and easy normal operation that also can directly influence the automatic turning production line is discharged in smear metal.Particularly in the automatic assembly line turning of medium and small bearing ring processing, because cutting output big (cutting with forming-tool), the length of chip of discharging during cutting is longer, easily around cutter or be stuck on the parts of equipment, thereby causes fault such as forge a knife, get stuck.2. cause the deviation from circular from of product big owing to high-rate cutting in the process of bearing ring turning converted products.3. in the process of bearing ring turning converted products withdrawing time-delay can't accurately to control the circularity scattered error that causes product big.
Summary of the invention
Defectives such as the technical problem that the present invention will solve and the technical assignment of proposition are to overcome existing feed control method to be prone to forge a knife, get stuck, and deviation from circular from is big provide a kind of bearing ring turning tool feeding method.
For achieving the above object, bearing ring turning tool feeding method of the present invention is that complete feed stroke is divided at least two sections strokes, after every section stroke finishes, carries out a withdrawing to break off smear metal.
As the optimization technique means: realize feed, withdrawing with digital controller control driven by servomotor planker.Complete feed stroke is divided into two sections strokes, and first section feed stroke, second section feed stroke are respectively 60-80%, the 40-20% of complete feed stroke.Adopt pneumatic apparatus to realize that loading and unloading, workpiece clamp, the quick shift-in of planker.
The invention has the beneficial effects as follows:
(1) breaks off smear metal through at least twice forward and back cutter, solve smear metal and curl up problem;
(2) through the action of at least twice forward and back cutter, can discharge the internal stress that causes owing to high-rate cutting, thereby reduce the distortion that workpiece causes because of internal stress;
(3) adopt the digitlization program control technology; Realize segmentation feeding pattern in the bearing ring turning process; Compare with the feeding of hydraulic lathe single, eliminated the internal stress that causes because of big cutting output, improved the dimensional accuracy and the form accuracy of bearing ring Vehicle Processing.
The specific embodiment
Below in conjunction with Figure of description the present invention is further specified.
Bearing ring turning tool feeding method of the present invention is that complete feed stroke is divided at least two sections strokes, after every section stroke finishes, carries out a withdrawing to break off smear metal.Concrete, realize feed, withdrawing with digital controller control driven by servomotor planker.As an example, complete feed stroke is divided into two sections strokes, first section feed stroke, second section feed stroke are respectively 60-80%, the 40-20% of complete feed stroke.
At present, hydraulic lathe turning bearing ring is selected in bearing ring turning processing, is because hydraulic lathe good rigidly, Cutting Force are big.But because hydraulic lathe adopts is hydraulic actuator feeding control model, difficultly realizes that moment withdrawing feed repeatedly moves, and can't solve smear metal around cutter, fault such as get stuck.Because hydraulic actuator feeding control model can't guarantee the stability of feeding when fast advance and retreat.If withdraw from feeding again, the one, the time does not allow, and secondary comes and goes the process-cycle prolongation, and production efficiency reduces; The 2nd, once can't correctly control with the secondary feed amount; The 3rd, for the first time feed speed also can't correctly be controlled with feed speed for the second time.Adopting moment during the withdrawing mode, feed is the amount of feeding and the amount of feeding for the second time for the first time, and feed speed just is difficult to control more with feed speed for the second time for the first time.Fact proved that general hydraulic part is the control that can't when repeatedly moment is advanced and retreat cutter, realize precise quantification.
Therefore, solve in the turning of medium-and-large-sized bearing transfer matic and curl up the problem of forging a knife, get stuck that produces, adopt the hydraulic feed pattern can't realize that moment withdrawing feed repeatedly moves because of smear metal.And the Digital Control pattern adopts the driven by servomotor planker, just can realize the precise quantification control of advance and retreat cutter.Size according to the product cutting output is set round feeding number of times and each amount of feeding, curls up the problem of forging a knife, get stuck that produces thereby solve in the turning of middle-size and small-size bearing transfer matic because of smear metal.
With 6310 bearing outer ring car raceway operations is example, with the about 850mm of hydraulic lathe processing feed primary feed length of chip, the processing beat be every 12 seconds, workpiece processing afterwards raceway circularity about 0.05mm.Drive the feed of planker employing secondary, withdrawing and control servomotor (like integrated digital controlled lathe) with digital controller: the amount of feeding is controlled at 70% of total cutting output for the first time; Carry out instantaneous withdrawing (the withdrawing amount is as the criterion to break off smear metal) after accomplishing this car sales volume, about bits length 500mm; The amount of feeding is controlled at 30% of total cutting output for the second time; Can lathe tool be withdrawed from fully after the feeding for the second time; About length of chip 350mm; The processing beat is every 11 seconds (because auxiliary movements such as loading and unloading, workpiece clamping, the quick shift-in of planker adopt pneumatic apparatus, speed is faster than hydraulic actuator, still shortens to some extent though be divided into the overall beat of secondary feed).In addition,, cut the withdrawing abrupt release in the first time and processed the stress that produces, made workpiece processing back raceway circularity less than 0.03mm owing to adopted the secondary feed.Both can improve the converted products quality, solve on the medium-and-large-sized bearing turning production line chip removal problem of forging a knife, get stuck again.
