Background technology
Honing is to utilize the honing head that has grinding stone that finishing is carried out in the hole; the polishing method for processing; its crudy is for the function of parts and have significant effects service life; in the heavy-duty machinery manufacturing; the inner surface that often has the large diameter, deep borehole of large-size workpiece need carry out honing processing; because it often matches with shaft-like workpiece; the required precision height; surface roughness often requires below Ra 0.8 μ m; difficulty of processing is very big; in present known technology; carrying out above-mentioned processing normally adopts by knife bar; axle; with the bar formula honing head that is inlaid in the strip grinding stone formation on the mandrel; not only structure is complicated for it, the manufacturing cost height, and because bore dia is big and dark; it is eccentric that honing head is produced, and makes dimensional accuracy and surface roughness after the processing be difficult to reach requirement.
Summary of the invention
The utility model provides a kind of simple in structure, low cost of manufacture, the honing head that the fine finishining large-diameter deep endoporus that machining accuracy is high is used for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The honing head that fine finishining large-diameter deep endoporus is used, it includes knife bar, oilstone clamping device and oilstone, the front end of knife bar radially has square hole, the oilstone clamping device is provided with a square transverse arm that is installed in the knife bar front end square hole, two ends at square transverse arm all have the long recess that leads to the termination, close rear side place in the long recess is fixed with baffle plate, the front side of baffle plate is equipped with spring bearer plate successively, spring and slide block, on baffle plate, be screwed pressure regulating screw, the tail end of pressure regulating screw leans on spring bearer plate, front end side at slide block has the backstop groove, on the outer wall of long recess front end, be screwed stop screw, its tail end is deep in the backstop groove of slip front side, long recess front end suitable for reading also is equipped with cover plate, two ends at square transverse arm are provided with oil stone base, and it is fastened on the front end of long recess inner slide with screw, and oilstone is fixed on the front end of oil stone base.
The utility model can also adopt following technical measures:
Square transverse arm is that sliding fit is installed in the square hole of knife bar front end.
Oil stone base is the flute profile oil stone base that front end has square three-way groove, and oilstone clamps in the square three-way groove that is fixed on flute profile oil stone base front end with screw.
Advantage and the good effect that the utlity model has are: with regard to the bar formula honing head of existing processing large diameter, deep borehole, the utility model is simple in structure, handling ease, low cost of manufacture, in addition because the square transverse arm of its oilstone clamping device is that sliding fit is installed in the knife bar, so when there is off-centre at knife bar and machine tool chief axis center slightly, knife bar will slide on square transverse arm, play self balancing effect, can improve machining accuracy effectively, be particularly suitable for the finished machined of large-diameter deep internal surface of hole.
