Abstract
The invention discloses a kind of endoporus grinding shaft and using method thereof, grinding shaft (2) is offered through hole (6) and screwed hole (3), through hole (6) runs through grinding shaft (2), the stage casing of grinding shaft (2) is divided into two halves along its axis, and the side sidewall of through hole (6) runs through along grinding shaft (2) radial direction by screwed hole (3); The outer wall of grinding shaft (2) has grinding groove.Structure of the present invention is simple, and easy to operate, machining accuracy is high, and economic performance is good simultaneously.Save a large amount of manual operations, efficiency is high, and grinding completely.
Description
Technical field
The present invention relates to a kind of grinding shaft and Ginding process thereof of inner bore grinding.
Background technology
Attrition process is generally applied in the endoporus batch machining of workpiece as a kind of technology application of comparative maturity.Grinding inner circle refining, finish reaming or carry out after right boring, need be generally hand lapping.Lap tool is open conical sleeve, and be enclosed within grinding agent on spindle taper and be applied between workpiece and lap tool, hand steered workpiece moves as axial reciprocating, and traditional lapping mode increases processing cost greatly.In engineering practice, the endoporus grinding that often there is a small amount of part is not in place, does not reach application request, needs to carry out a small amount of surplus to part again and process.
Summary of the invention
The technical problem to be solved in the present invention: the inefficiency existed for present endoporus Ginding process and the incomplete problem of grinding, provide a kind of endoporus grinding shaft and Ginding process thereof.
Technical solution of the present invention:
A kind of endoporus grinding shaft, grinding shaft is offered through hole and screwed hole, through hole runs through grinding shaft, and the stage casing of grinding shaft is divided into two halves along its axis, and the side sidewall of through hole runs through along grinding shaft radial direction by screwed hole; The outer wall of grinding shaft has grinding groove.
Through hole is elongate holes.
Screwed hole is perpendicular to the length direction of through hole.
Be provided with two screwed holes, run through by the material of through hole both sides respectively, the axis of two screwed holes does not overlap.
The opposite side through-hole side wall of corresponding screwed hole through part offers screw locating slot.
There is the top locating slot of lathe one end of grinding shaft.
Mounting screw in screwed hole, screw does not expose grinding shaft.
Use the method for above-mentioned endoporus grinding shaft inner bore grinding, comprise the following steps: one, workpiece is enclosed within grinding shaft stage casing, rotate the screw in screwed hole, to reasonable swelling between grinding shaft and inner hole of workpiece in the radial direction; Two, grinding shaft is arranged on lathe, in grinding groove, deposits abrasive sand; Three, select lathe Rational Rotation Speed, holding workpiece is ground.
Beneficial effect of the present invention:
Grinding shaft has axial rectangular through holes, by the screw effect of vertical direction, grinding shaft radial direction can be swollen, thus grinding shaft can be fitted tightly with polished inner hole of workpiece better, thus effectively grind.Grinding shaft has grinding groove, can make abrasive sand stored in.Structure of the present invention is simple, and easy to operate, machining accuracy is high, and economic performance is good simultaneously.Save a large amount of manual operations, efficiency is high, and grinding completely.
accompanying drawing illustrates:
Fig. 1 is the structural representation after the present invention is arranged on lathe.
Fig. 2 is that the A-A of Fig. 1 is to profile.
detailed description of the invention:
As figure, grinding shaft 2 be cylindrical, and there is the top locating slot of lathe one end, and grinding shaft 2 outer round surface has grinding groove, and grinding groove can be the surperficial minor groove of helix of axial direction, also can be pitting one by one, be mainly used for abrasive sand stored in.Its stage casing is separated into two halves by the through hole 6 of strip vertically, but two ends still connect together, and the sidewall of through hole 6 both sides has a screwed hole 3 respectively, screwed hole 3 is perpendicular to through hole 6, two screwed holes 3, run through by the material of through hole 6 both sides respectively, the axis of two screwed holes 3 does not overlap.Opposite side through hole 6 sidewall of corresponding screwed hole 3 through part offers screw locating slot, mounting screw in screw thread 3, by rotary screw, just through hole 6 can be supportted greatly, thus grinding shaft 2 is swollen, become more slightly a bit.
Select the grinding shaft 2 matched with workpiece 4 endoporus, chuck 1 is grabbed with three in grinding shaft 2 one end and is clamped on lathe, workpiece 4 is inserted in grinding shaft 2, grinding shaft 2 other end lathe centre 5 withstands.Be rotatably mounted on the swelling screw of grinding shaft 2 upper screwed hole 3 li, in radial directions by swelling reasonable between grinding shaft 2 and workpiece 4 endoporus, deposit abrasive sand by the grinding groove on grinding shaft 2, select lathe Rational Rotation Speed, holding workpiece 4 is ground.
