Abstract
The invention discloses a fine tuning boring cutter comprises a boring bar, a cutter rod and a cutter head. The cutter rod is mounted in a mounting hole in the boring bar, the cutter head is fixedly mounted on the cutter rod, the boring bar is provided with a set screw used for fixing a cutter rod, an adjusting bolt is disposed in the mounting hole in the boring bar, the adjusting bolt is composed of a bolt adjusting end and a bolt connecting end, the bolt adjusting end is threaded to the mounting hole, the bolt connecting end is threaded to the cutter rod, and the pitch of the bolt adjusting end is different from that of the bolt connecting end. The feed rate of the boring cutter can be finely tuned because the pitches of the threads in the adjusting bolt are different. The fine tuning boring cutter is simple in structure, convenient to use and high in tuning precision. The fine tuning boring cutter is suitable for processing fine borings in common lathes and boring machines.
Description
Technical field
The present invention relates to field of machining, particularly a kind of boring cutter utilizing bolt thread to finely tune the processing amount of feeding.
Background technology
Along with the development of machine tools technology, the use of micrometer adjustement boring tool on engine lathe, boring machine is more and more extensive.During the hole that large aperture, required precision are high on processing equipment part, conventional method processes with boring cutter on thorax bed.The size of bore diameter is determined by the distance of point of a knife to boring cutter pivot.The boring cutter that boring machine uses is generally be contained in the installing hole of boring bar by cutter head, use screw or bolt presses, the point of a knife of cutter head can only lean on the position of each push type broach to realize to the distance of boring cutter pivot, adding man-hour like this, regulate during cutter head and not only bother, and the positional precision of cutter head cannot be ensured; Particularly when boring precision holes, both cannot ensure crudy, and also operating efficiency can be caused lower because of the time regulating cutter head to cost a lot of money.
Summary of the invention
Technical problem to be solved by this invention there are provided the micrometer adjustement boring tool that structure is simple, easy to use, Adjustment precision is high.
For solving the problems of the technologies described above, present invention employs a kind of micrometer adjustement boring tool, comprise boring bar, knife bar and cutter head, described knife bar is arranged in the installing hole of boring bar, described cutter head is fixedly mounted on knife bar, described boring bar is provided with holding screw, for fixing knife bar, adjusting bolt is provided with in described boring bar installing hole, described adjusting bolt is made up of bolt adjustable side and bolted end, described bolt adjustable side and installing hole are threaded connection, described bolted end is connected with knife bar by screw thread, the pitch of described bolt adjustable side is different from the pitch of bolted end.
The beneficial effect that the present invention has: this boring cutter utilizes the pitch difference between adjusting bolt screw thread, finely tunes the depth of cut of boring cutter, has that structure is simple, easy to use, Adjustment precision advantages of higher, is suitable for carrying out right boring processing on engine lathe, boring machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, boring bar; 2, knife bar; 3, cutter head; 4, adjusting bolt; 5, bolt adjustable side; 6, bolted end; 7, holding screw; 8, installing hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, a kind of micrometer adjustement boring tool, comprise boring bar 1, knife bar 2 and cutter head 3, knife bar 2 is arranged in the installing hole 8 of boring bar 1, cutter head 3 is fixedly mounted on knife bar 2, boring bar 1 is provided with holding screw 7, for fixing knife bar 2, adjusting bolt 4 is provided with in boring bar 1 installing hole 8, adjusting bolt 4 is made up of bolt adjustable side 5 and bolted end 6, bolt adjustable side 5 and installing hole 8 are threaded connection, and bolted end 6 is connected with knife bar 2 by screw thread, and the pitch of bolt adjustable side 5 is different from the pitch of bolted end 6.
When using spanner to turn adjusting bolt 4, the advance of cutter head 3 or backway are the difference P of the pitch between bolt adjustable side 5 and bolted end 6; Again owing to having individual angle [alpha] between knife bar 2 and workpiece hole central axis, therefore the actual amount of feeding of cutter head 3 is Psin α.A bite of enclosing can be rotated by precalculated spanner when designing, or portray at the spiral shell aperture periphery of boring bar 1 scale that 1 circle has decile, namely often rotate a scale and can obtain the corresponding depth of cut; At this moment again holding screw 7 is withstood on knife bar 2, its knife bar 2 is fixed.
