Abstract
The invention discloses a bore grinding shaft and an application method thereof. A grinding shaft (2) is provided with a through hole (6) and a threaded hole (3). The through hole (6) penetrates the grinding shaft (2) to axially divide the middle of the grinding shaft (2) into two halves. The threaded hole (3) radially penetrates one side wall of the through hole (6) along the grinding shaft (2). The outer wall of the grinding shaft (2) is provided with a grinding groove. The bore grinding shaft is simple in structure, convenient to operate, high in machining precision, well economical, greatly manual-operation-saving, efficient, and through in grinding.
Description
Technical field
The present invention relates to a kind of grinding shaft and Ginding process thereof that grinds endoporus.
Background technology
Attrition process is used widespread usage in the endoporus batch machining of workpiece as a kind of technology of comparative maturity.Grind grinding out need correct grinding, finish ream or right boring after carry out, be generally hand lapping.Lap tool is the opening tapered sleeve, is enclosed within that grinding agent is applied between workpiece and the lap tool on the tapering axle, and hand steered workpiece axially moves back and forth, and traditional lapping mode has strengthened processing cost greatly.In the engineering practice, tend to exist the endoporus grinding of a small amount of part not in place, do not reach application request, need 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: inefficiency and the incomplete problem of grinding at present endoporus Ginding process exists provide a kind of endoporus grinding shaft and Ginding process thereof.
Technical solution of the present invention:
A kind of endoporus grinding shaft is offered through hole and screwed hole on the grinding shaft, through hole runs through grinding shaft, and the stage casing of grinding shaft is divided into two halves along its axis, and screwed hole radially runs through a side sidewall of through hole along grinding shaft; Have grinding groove on the outer wall of grinding shaft.
Through hole is the strip hole.
Screwed hole is perpendicular to the length direction of through hole.
Be provided with two screwed holes, respectively the through hole material at opposite sides run through, the axis of two screwed holes does not overlap.
Opposite side through-hole side wall at corresponding screwed hole through part offers the screw locating slot.
One end of grinding shaft has the top locating slot of lathe.
Mounting screw in screwed hole, screw do not expose grinding shaft.
Use above-mentioned endoporus grinding shaft to grind the method for endoporus, may further comprise the steps: one, workpiece is enclosed within the grinding shaft stage casing, the screw in the rotation screwed hole is to swelling rationally between grinding shaft and the workpiece endoporus in the radial direction; Two, grinding shaft is installed on the lathe, in grinding groove, deposits abrasive sand; Three, select the reasonable rotating speed of lathe, holding workpiece is ground.
Beneficial effect of the present invention:
Have axial rectangular through holes at grinding shaft, can grinding shaft radially be swollen by the screw effect of vertical direction, thereby make grinding shaft to fit tightly better with by the grinding work-piece endoporus, thereby effectively grind.Have grinding groove on the grinding shaft, can make that abrasive sand deposits in.The present invention is simple in structure, and is easy to operate, the machining accuracy height, and economic performance is good simultaneously.Saved a large amount of manually-operateds, the efficient height grinds fully.
Description of drawings:
Fig. 1 is installed in structural representation behind the lathe for the present invention.
Fig. 2 is that the A-A of Fig. 1 is to profile.
The specific embodiment:
As figure, grinding shaft 2 is cylindrical, and an end has the top locating slot of lathe, and grinding shaft 2 outer round surface have grinding groove, and grinding groove can be the helix surface minor groove of axial direction, also can be pitting one by one, mainly is depositing in for abrasive sand.Its stage casing is separated into two halves by the through hole 6 of strip vertically, but two ends still connect together, and a screwed hole 3 arranged respectively on through hole 6 side walls, screwed hole 3 is perpendicular to through hole 6, two screwed holes 3 run through through hole 6 material at opposite sides respectively, and the axis of two screwed holes 3 does not overlap.Opposite side through hole 6 sidewalls at corresponding screwed hole 3 through parts offer the screw locating slot, mounting screw in screw thread 3, and by rotary screw, just can through hole 6 supports are big, thus grinding shaft 2 is swollen, become thicker.
Selection and the grinding shaft 2 that workpiece 4 endoporus are complementary are grabbed chuck 1 with grinding shaft 2 one ends with three and are clamped on the lathe, and workpiece 4 is inserted in grinding shaft 2, and grinding shaft 2 other ends withstand with lathe centre 5.Rotation is installed in the swelling screw of 3 li of grinding shaft 2 upper screwed holes, and swelling rationally between in the radial direction with grinding shaft 2 and workpiece 4 endoporus will be deposited abrasive sand in the grinding groove on the grinding shaft 2, the reasonable rotating speed of selection lathe, and holding workpiece 4 is ground.
