Screw thread cuts general form cutter machining internal thread on workpiece, mainly contains turning, milling etc. Under normal circumstances, by workpiece to be processed clamping on chuck, rotational workpieces, first processes inner circle, then changes cutter, and by screw thread blade machining internal thread, complex procedures, and single blade cutting stock-removing efficiency is low, and blade life is short and then adds production cost.
Summary of the invention
Technical problem to be solved in the utility model is: providing a kind of without the need to changing cutter, operation is simple, the chuck screw thread cutter that stock-removing efficiency height, blade life are high.
The technical scheme in the invention for solving the above technical problem is: a kind of chuck screw thread cutter, described chuck screw thread cutter comprises N number of N number of chuck seat being fixed on machine chuck and can adjust position along chuck radial direction, each chuck seat is equipped with blade erecting frame, each blade erecting frame is equipped with and puts cutter groove for what install blade, each is put in cutter groove and is equipped with blade, the cutting edge of each blade is all in machining position, described N >=1 and be integer.
Compared with prior art, the utility model has the advantage of: by workpiece to be processed clamping, adjust center, the cutting diameter adjusting each blade cut sword is put at radial adjustment machine chuck upper chuck seat, the path that the cutting diameter D being positioned at the blade cut sword of bottom is adjusted to work piece internal thread, the cutting diameter of all the other blade cut swords vertically the X all blades simultaneously that sequentially successively decrease all be in machining position; Start lathe, chuck and workpiece to be machined relatively rotated, by workpiece to be machined feeding vertically, chuck screw thread cutter vertically X process workpiece to be machined, multiple blade coordinate sequentially roughing semi-finishing precision work to go out interior hole that diameter is diameter of thread; Stop relatively rotating of chuck and workpiece, the cutting diameter adjusting multiple blade cut sword is put at radial adjustment machine chuck upper chuck seat, the big footpath that the cutting diameter E being positioned at the blade cut sword of the top is adjusted to work piece internal thread, the cutting diameter of all the other blade cut swords vertically the X all blades simultaneously that oppositely sequentially successively decrease all be in machining position; Chuck and workpiece are relatively rotated, by workpiece to be machined vertically X exit screw thread chuck cutter, exit in process, multiple blade coordinates sequentially roughing semi-finishing precision work to go out internal thread; Stop rotating chuck, unload workpiece to be machined, completion of processing, whole process without the need to changing cutter can process interior hole and internal thread, operation is simple, and multiple blade coordinates chip, and stock-removing efficiency height, improves blade life simultaneously.
Improve as one of the present utility model, the difference of altitude of the cutting edge of each blade described on axial X is P/N, described P is the pitch of workpiece to be machined screw thread, by described improvement, the cutting circle at each cutting edge place height interval P/N in the axial direction arranges, screw thread cutting force shared by multiple cutting edge simultaneously, the pressure that each blade is subject to is little, protection cutting edge, blade life is long, multiple cutting edge is processed simultaneously, cut fast, the different positions of iron filings in chuck screw thread cutter circumference produces, iron filings are avoided to be wound around the cutting edge temperature caused too high, serious wear, the problem of cutting edge easy fracture.
A kind of improvement is also had as of the present utility model, described chuck seat and blade erecting frame are split type, by described improvement, it is possible to adjust the round difference of altitude in the axial direction of cutting of cutting edge formation by installing the blade erecting frame of different heights difference, thus regulate the pitch of screw thread to be processed.
A kind of improvement is also had as of the present utility model, described blade is trilateral, three angles of described trilateral are three cutting edges, each blade described has a cutting edge to be in machining position, and by described improvement, blade has three cutting edges, blade position can be adjusted by open holes, the rotating blade when a certain cutting edge lost efficacy, it may also be useful to remaining cutting edge carrys out work, blade overall utilization rate height.
A kind of improvement is also had as of the present utility model, the side of described N number of chuck seat at least one be provided with the auxiliary blade cut out along chuck seat thickness direction and put cutter groove, described auxiliary blade is put and is installed auxiliary blade in cutter groove, the auxiliary blade cutting edge dew of described auxiliary blade is put outer at chuck seat end face and is in assisted machining machining position, by described improvement, when workpiece to be machined is fed to bottom chuck screw thread cutter, auxiliary blade can complete chamfering or the operation of fillet or making step or face work, exempt and again will use tool sharpening chamfering or the additional process of step or face work after piece-holder, working (machining) efficiency height ensures the concentricity at each processing position simultaneously.
A kind of improvement is also had as of the present utility model, described auxiliary blade cutter hub is provided with multiple auxiliary blade cutting edge, the auxiliary blade open holes for making it be fixed on knife rest it is provided with in the middle part of described auxiliary blade, by described improvement, when one of them auxiliary blade cutting edge lost efficacy, install after auxiliary blade can be rotated, it may also be useful to other auxiliary blade cutting edge processes, it is to increase auxiliary blade overall utilization rate.
Also having a kind of improvement as of the present utility model, the quantity of described chuck seat is three, and described quantity is the chuck seat quantity of general oild chuck, and three blades meet cutting needs substantially.
