The boring grab of the above-mentioned type to workpiece to be processed location typically require arrange on fixture for splined shaft, and the chucking power of whole workpiece to be processed is to realize axial location by packing ring and opening pressing plate, and the axial workpiece being directed to end band spline still cannot be suitable for above-mentioned boring grab, it is therefore desirable to a kind of Special drill jig.
Utility model content
The deficiency existed for prior art, the purpose of this utility model be to provide a kind of can the spline that positions of the axial workpiece of key wounded in the battle to end to tooth boring grab.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of spline is to tooth boring grab, including drill bushing seat, described drill bushing seat is provided with the notch concaved, the upper wall of described notch is provided with the first through hole stretched into for drill bit, the cell wall adjacent with the first through hole in described notch is provided with installing hole, is provided with spline in described installing hole.
Pass through technique scheme, in actual use, the splined end of axial workpiece to be processed is inserted in installing hole, and cooperate with the spline in installing hole, drill bit on boring bar tool is inserted into from the first through hole thus countershaft class part outer week sidewall realizes Drilling operation, and meanwhile, the splined end of axial workpiece to be processed matches with spline, can effectively limit the axial-rotation of axial workpiece, and then smoothly complete the Drilling operation to axial workpiece circumferential side wall；Above-mentioned boring grab need not the unilateral clamping of the axial workpiece by key wounded in the battle to end and realizes location, can realize the purpose of axial workpiece circumferential side wall punching.
Preferably, being provided with installation set in described installing hole, described spline is positioned on the trepanning installing set.
Pass through technique scheme, after the axial workpiece of band spline repeatedly coordinates for a long time with installation set in high volume, the spline installed in set there will be state of wear too, once wearing and tearing, will become no longer tight coordinating between axial workpiece with spline, machining accuracy is affected, now, original function of spline can be recovered by the way of directly changing and set is installed, not only reduce maintenance cost, and improve maintenance efficiency.
Preferably, described set of installing is less than notch inwall near the set face of notch position.
Pass through technique scheme, set is installed and can form a step groove between set face and the notch inwall of notch position, and be directed to end with spline and the axial workpiece with step for, while the spline of end cooperates with the spline installed in set, the step of axial workpiece can coordinate with step groove, so fit system, for being directed to axial workpiece with the level, can effectively promote axial workpiece with installing and coordinate compactness between set.
Preferably, described set lateral wall of installing is provided with the first quenching layer.
By technique scheme, the first quenching layer can be effectively increased wear resistence and the hardness installing set lateral wall, and the service life making installation overlap is longer.
Preferably, the lower wall of described notch is provided with the second through hole, and described second through hole and the first through hole are correspondingly arranged.
By technique scheme, in order to can guarantee that drill bit can thoroughly drill axial workpiece, first drill bit can enter in the first through hole, then pierces axial workpiece, in drill bit enters back into the second through hole afterwards, it is achieved thereby that drill the purpose of axial workpiece completely.
Preferably, also including fairlead, described fairlead is fixing to be positioned at drill bushing seat lateral wall and is correspondingly arranged with the first through hole, communicates inside the trepanning of described fairlead and the first through hole.
By technique scheme, the setting of external fairlead, while drill bit pierces axial workpiece, it is first subjected to the guide effect of external fairlead, thus limits the vibrations of the radial direction of drill bit, promote borehole accuracy.
Preferably, described fairlead is provided with solid choma away from the end of drill bushing seat.
Pass through technique scheme, its length of traditional drill bit is the longest, thus inevitably there is situation about radially rocking in drill bit, and occur that the drill bit radially rocked can first pass through and contact away from the end of drill bushing seat at fairlead, Gu choma can effectively promote the fairlead collar extension structural strength away from drill bushing seat end, thus promotes the guide effect of fairlead further.
Preferably, described solid choma flushes away from the end of drill bushing seat with fairlead away from the end face of drill bushing seat.
Pass through technique scheme, owing to fairlead is the position being easiest to reaming phenomenon occur away from the end of drill bushing seat, and choma flushes away from the end of drill bushing seat with fairlead away from the end face of drill bushing seat admittedly, the solid mouth effect that can make solid choma maximizes, at utmost ensure the fairlead stability away from the end of drill bushing seat, thus ensure the structural stability of drill bushing seat.
Preferably, described solid choma is provided with the second quenching layer away from the end face of drill bushing seat.
By technique scheme, the second quenching layer can effectively promote the solid choma structural rigidity away from the end face of drill bushing seat, even if because and maloperation makes drill bit directly be drilled on this end face, this end face also will not be made to occur significantly boring wound, it is ensured that Gu the solid mouth effect of choma.
Preferably, the cell wall near the first through hole of described notch is provided with twice stress grooving, and twice stress grooving is respectively communicated with in the first through hole and installing hole, the second through hole and installing hole.
Pass through technique scheme, after being inserted into spline due to object to be processed, whole object to be processed can produce bigger oppressive force for the hole wall of installing hole, and the gravity direction that object to be processed is subject to is always straight down, the oppressive force direction of installing hole hole wall is: the orientation between the first through hole and installing hole, between the second through hole and installing hole is consistent；Therefore, stress grooving is set, can reduce and concentrate at the first through hole and installing hole, stress between the second through hole and installing hole, reduce stress and concentrate and produce the damage to boring grab.
