Background technology
Along with the development of science and technology, more and more higher to the requirement of machining accuracy, although process equipment precision is higher, but with horizontal boring machine processing single-piece or the accurate endoporus of small batch, when right boring, because allowance is very little, the dimensional requirement of machining hole is very high, when heavy boring and half right boring, in order to ensure processing request, reduce the regulation time of tool changing and tool diameter, boost productivity and adopt common hole boring cutter rod, the diameter adjustment of cutter is very difficult, be difficult to the requirement reaching aperture size precision, and to operator's technology and skill requirement higher, labor strength is large, production efficiency is also very low.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, easy to operate, can greatly increase work efficiency, can accurate to dimension be ensured again, greatly alleviate the multi-functional adjustment boring bar of labor strength.
The multi-functional adjustment boring bar of the present invention, comprise the taper shank matched with boring machine boring axle front end taper hole, described taper shank afterbody is provided with a cylindric overcoat, described overcoat one side end face has the blind hole of a band boss, a screw rod is provided with in blind hole, match with blind via bottom in screw rod one end, the other end is connected with end cap by screw thread, described screw rod is also threaded connection the column wedge of a band skewed slot, wedge can slide in overcoat, on described wedge, corresponding to skewed slot, overcoat relevant position has an aperture, a sliding sleeve is provided with in hole, in described sliding sleeve, boring cutter is installed.
Preferably, wedge is connected with the boss putting blind hole outward by spring.
Preferably, the screw thread that screw rod matches with wedge is identical with the thread rotary orientation that screw rod matches with end cap, and the pitch of the screw thread that screw rod matches with wedge is less than the pitch of the screw thread that screw rod matches with end cap.
Preferably, multi-functional adjustment boring bar, also comprises a pointer, it is characterized in that, described pointer is connected with screw rod end winding support and is close to end cap, is provided with dial on outside described end cap.
Structure of the present invention is simple, easy to operate, can greatly increase work efficiency, and ensures accurate to dimension again, greatly alleviates labor strength.

Detailed description of the invention
The multi-functional adjustment boring bar of the present invention, comprise the taper shank 1 matched with boring machine boring axle front end taper hole, it is characterized in that, described taper shank 1 afterbody is provided with a cylindric overcoat 2, described overcoat 2 one side end face has the blind hole of a band boss, a screw rod 3 is provided with in blind hole, match with blind via bottom in screw rod 3 one end, the other end is connected with end cap 4 by screw thread, described screw rod 3 is also threaded connection the column wedge 5 of a band skewed slot, wedge 5 can slide in overcoat 2, on described wedge 5, corresponding to skewed slot, overcoat 2 relevant position has an aperture, a sliding sleeve 6 is provided with in hole, in described sliding sleeve 6, boring cutter is installed.Wedge 5 is connected with the boss of blind hole on overcoat 2 by spring 7.Identical with the thread rotary orientation that end cap 4 matches with screw rod 3 with the screw thread that wedge 5 matches on screw rod 3, and the pitch of the screw thread that screw rod 3 matches with wedge 5 is less than the pitch of the screw thread that screw rod 3 matches with end cap 4.Multi-functional adjustment boring bar, also comprises a pointer 8, and described pointer 8 is connected with screw rod 3 end winding support and is close to end cap 4, is provided with dial on outside described end cap 4.
Screw rod 3 is identical with the thread rotary orientation that end cap 4 matches with screw rod 3 with the screw thread that wedge 5 matches, and the pitch of the screw thread that screw rod 3 matches with wedge 5 is less than the pitch of the screw thread that screw rod 3 matches with end cap 4, but pitch difference is very little, composition differential screw structure.
During fine setting, unclamp the nut that screw rod 3 is connected with end cap 4, tighten the nut that end cap 4 is connected with overcoat 2, rotating screw bolt 3, wedge 5 can move as slight distance in overcoat 2 endoporus, force boring cutter to move radially certain distance e under skewed slot effect thereon, bore hole diameter be the distance 2e of twice boring cutter movement;
Wedge 5 displacement
, in formula
for screw rod 3 to match with end cap 4 helical pitch of screw thread,
for screw rod 3 to match with wedge 5 helical pitch of screw thread,
for the corner of screw rod 3.
Then cutter head radially the distance e of movement and screw rod 3 angle relation be:
, (
for skewed slot inclination angle on wedge 5), so when screw rod 3 rotates
during angle, aperture increases to:
The adjustment amount of such tool diameter directly can be read from dial by screw rod 3 corner, and overcoat 2 inner spring 7 is used for eliminating the gap in screw pair, and like this, the size adjusting amount of cutter just can directly read from dial, improves the dimensional accuracy in hole.
During coarse adjustment, tighten the nut that screw rod 3 is connected with end cap 4, unclamp the nut that end cap 4 is connected with overcoat 2, rotating screw bolt 3, end cap 4 rotates with screw rod 3, removes differential screw mechanism, rotating screw bolt 3, drives wedge 5 to move in overcoat 2 endoporus
, with the corner of screw rod 3
pass be:
,
Aperture increases to:
;
In formula:
for screw rod 3 to match with wedge 5 helical pitch of screw thread,
for the corner of screw rod 3,
for skewed slot inclination angle on wedge 5,
The adjustment amount of coarse adjustment tool diameter directly can be read by respective value on the dial on end cap 4.
