Description
Technical field
The utility model belongs to technique roller process equipment, relates in particular to roller class workpiece processing elastic anti-slip axle sleeve.
Background technology
In modern metallurgical production technological equipment, using in a large number various types of roller base parts, wherein there is the hollow roller of a type, its common feature is, the very large and shaft head split axle of barrel diameter small-sized, for example, the various technique rollers of flat cold-rolled sheet production line all belong to this class roller, and zinc-plated sinking roller is exactly wherein typically a kind of.This class roller carries out turning when processing and manufacturing, cutting force operating radius is very large, and because spindle nose diameter is very little, the driving torque that the chucking power of machine chuck claw on spindle nose clamping face produces is not enough to overcome the resistance that cutting force produces, often cause between claw and spindle nose clamping face and occur skidding, lathe workpiece cut in normal rotation rotates.Once lathe occurs skidding when turning, can bring a series of serious consequences, the lighter causes tool damage, workpiece to damage, and severe one causes equipment breakdown or personnel's injury.
While processing this type of processing of roller in order to overcome, occur skidding, current way mainly contains two kinds at present:
Method is to adopt a little cutting data, reduces the cutting depth of cutter and the amount of feeding of lathe, by adjusting Cutting Process parameter, cutting force is reduced to a certain degree, guarantees not occur skidding.The shortcoming of this method is, for the larger roller of barrel diameter, the cutting data adopting will be less, so just greatly extended process time, reduced the operating efficiency of lathe, and lathe can not normally be brought into play due work efficiency.
Another kind method is on spindle nose, to weld the technique axle sleeve of Yi Ge inner circle foreign side, and the inner hole sleeve of axle sleeve, on roller spindle nose, and is welded into integral body with spindle nose; Axle sleeve outside is square, and lathe chuck claw is stuck in the outside of axle sleeve, has so just stopped the possibility of skidding.The shortcoming of this method is that, because axle sleeve employing welding manner is arranged on spindle nose, after completion of processing, dismounting again, very inconvenient; After dismounting, need the welding portion of spindle nose to repair polishing, time-consuming; Rewelding affects the mechanical property of spindle nose, and axle sleeve Rewelding, cutting cause axle sleeve deformed damaged, uses for several times limited.
Utility model content
The defect existing in order to overcome prior art, the purpose of this utility model is to provide a kind of zinc-plated sinking roller processing and uses elastic anti-slip axle sleeve, adds the generation of skidding in man-hour to stop turning, improves machine tooling work efficiency; Axle sleeve easy accessibility, long service life.
Elastic anti-slip axle sleeve is used in zinc-plated sinking roller processing, axle sleeve inner circle foreign side, and inner circle coordinates with roll shaft spindle nose, be loaded on spindle nose, be characterized in, axle sleeve circumferencial direction is all established the axial plane connecing in four, between axial plane, by arc surface, connected, turning adds man-hour, four planes of chuck jaws clamping; Axle sleeve one side shaft is established the open slot of vertical this plane to in-plane, bottom land disconnects, and its center line passes through the center of circle; The upper and lower both sides of described open slot are provided with locking screw keyhole, and upside is established and strutted screwed hole, and clamping screw is loaded in bolt hole and is fixed by nut, strut screw and are loaded in screwed hole; Compensating groove is established at the arc surface middle part of described both sides, open slot opposite, bottom land arc surface connects, to reduce axle sleeve rigidity, increase elasticity, be convenient to mount and dismount axle sleeve, increase locking effect, make axle sleeve inner surface on spindle nose surface, apply more reliably required normal pressure, guaranteeing provides required frictional force effectively, stops to add the skidding that produce man-hour.
The utility model further improves, four axial plane equal and opposite in directions on described axle sleeve, and two relative axial planes are parallel to each other, and two adjacent axial planes are orthogonal, and vertical center line and cross central line meet at the axle sleeve inner circle center of circle.
The utility model further improves, and described open slot is the center line setting of plane vertically, and width 2～5 mm open or close up at the effect under shed groove that struts screw, to facilitate axle sleeve to install on spindle nose and take off; In the effect under shed groove locking of clamping screw, axle sleeve clamps roll shaft spindle nose.
The utility model further improves, and described compensating groove is located at the arc surface middle part of both sides, open slot opposite, and bottom land is arcwall face, and its center line and open slot center line angle are 45 °.
During use, first with strutting screw, open slot is strutted to the aperture to needs, axle sleeve can be set with on spindle nose smoothly, then returns and struts screw, tightens clamping screw nut, and axle sleeve is fastened on spindle nose.Add man-hour, chuck is clamped four axial planes on axle sleeve, can process.Whole of endoporus who is axle sleeve due to axle sleeve and the contact-making surface of spindle nose contacts, contact area directly clamps the contact area of spindle nose much larger than chuck jaws, the maximum static friction force that the maximum static friction force that can provide will provide when claw directly clamps spindle nose, be enough to provide while overcoming the needed driving torsion of cutting resistance, between inner hole of shaft sleeve and spindle nose, just there will not be relative sliding, guarantee to cut and normally carry out, after process finishing, nut is unscrewed, tighten and strut screw, open slot is opened, and axle sleeve can easily unload.
Compared with prior art, advantage is: novel, simple and reasonable for structure, use reliably, and effectively overcome skidding; Handling axle sleeve is convenient, fast, improves lathe work efficiency; Reduce or avoid damaging cutter because spindle nose skids, workpiece is scrapped and the generation of equipment breakdown; Do not affect or reduce roll shaft spindle nose mechanical property, being conducive to normally carrying out of zinc-plated production, can application in the processing of roller class workpiece.
