Description
Technical field
The utility model belongs to field of machining, more particularly to a kind of boring cutter for processing large-diameter coaxial hole fills
It sets.
Background technique
Coaxial aperture is processed on common horizontal boring machine generally using bearing boring method, i.e. one end of boring bar is bored mounted in boring spindle
In hole, the other end is supported using the fulcrum bearing of boring machine tailstock column, the built-in boring cutter of square hole among boring bar, the tune by way of percussion
The extension elongation of whole boring cutter controls the size of bore hole.Rigidity using boring bar when bearing boring method processing is preferable, is suitble to processing
Deeper coaxial aperture, but which, since boring bar is through entire workpiece, common inside micrometer or dial gauge cannot be to institute's bore holes
Diameter measures, and the size of bore hole is by tapping boring cutter control, and examination boring, measurement, adjustment boring cutter are cumbersome when processing, the precision of bore hole
It is not easy to control；And when using which processing large diameter hole, boring cutter stretching boring bar is longer, and rigidity is poor, and it is existing to be also easy to produce vibration knife
As the hole poor accuracy processed.
Summary of the invention
To solve the above problems, the boring cutter dress that the utility model proposes a kind of for processing large-diameter coaxial hole
It sets, which is suitable for processing large-diameter coaxial hole, convenient for measuring to the aperture of institute's boring and the adjustment to boring cutter, significantly
Improve machining accuracy.
To achieve the goals above, the utility model uses following scheme, comprising:
Boring bar, the left end of boring bar are taper shank, and the right end of boring bar is cylindrical supporting part, the middle part setting radial direction of boring bar
Knife bar installation through-hole, a pair of of fastening thread hole is arranged on the circumferential surface of boring bar, which is connected to knife bar installation through-hole, fastening
The radial measurement through-hole of the right side setting of threaded hole, the measurement through-hole is perpendicular to knife bar installation through-hole；
The knife bar being embedded in knife bar installation through-hole, the knife bar can move up and down in knife bar installation through-hole, outside knife bar
Circumferential surface is equipped with axially extending platform, and fastening screw compresses platform after screwing in fastening thread hole, and the one end of knife bar is cuboid,
The one side of perpendicular cuboid is equipped with microboring head mounting hole with platform surface, and the other two sides of cuboid are set respectively
There is the positioning spiro pit of connection microboring head mounting hole；
The microboring head being embedded in microboring head mounting hole, the microboring head can be in microboring head mounting holes
Interior rotation is adjusted, and positioning screw locks microboring head after screwing in positioning spiro pit.
The taper shank is Morse taper shank.
The positioning screw is cone screw.
The utility model is suitable for processing large-diameter coaxial hole, convenient for measuring and the aperture of institute's boring to boring cutter
Adjustment, substantially increases machining accuracy.
