Technical field
The utility model relates to a kind of boring cutter that is used for cutting metal, relates in particular to a kind of multiple-cutting-edge boring cutter.
Background technology
Modular twolip heavy boring cutter is widely used in field of machining, compare with integral type single-blade heavy boring cutter, modular twolip heavy boring cutter has many advantages: because twolip heavy boring cutter in process, has two blades to participate in cutting simultaneously, stock-removing efficiency is higher; And the radial load that acts on the cutting edge of two symmetries cancels out each other, and makes boring bar be difficult for producing vibration etc.
An existing Chinese utility model patent, publication number CN201120473, disclose " a kind of twolip is adjustable heavy boring cutter " in 2008.09.24, comprise cutter hub and tool rest, described cutter hub end is equipped with guide rail, described tool rest can slide along described guide rail, and a side of tool rest is equipped with tool rest and adjusts bolt, places the tool rest clamping screw in the described tool rest mounting hole that described tool rest is fixedlyed connected with described cutter hub.
But the boring cutter in these twolip boring cutters is identical around the cutting diameter that central axis rotates, and such structure can only boring goes out a kind of aperture of size, can not process different apertures simultaneously.
The utility model content
The utility model provides a kind of multiple-cutting-edge boring cutter that can process different apertures simultaneously at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of multiple-cutting-edge boring cutter comprises the operator handle, and the perisporium of described operator handle is provided with at least two boring cutter, the cutting diameter that the cutting diameter that the described boring cutter that is positioned at the lower end rotates around central axis rotates around central axis less than the described boring cutter that is positioned at the upper end.
In the technique scheme, also be provided with chamfering blade on the perisporium of operator handle, the blade of described chamfering blade has angle with the central axis of operator handle, such structure, boring cutter is when boring, just realize the chamfering of workpiece simultaneously, thereby economized the chamfer machining operation one, improved production efficiency greatly.
In the technique scheme, described boring cutter is installed on the operator handle by the boring cutter locking device that boring cutter can be locked in a position, so just can adjust every the distance of boring cutter on central axial direction, thereby can adjust the degree of depth in hole on the workpiece.
In the technique scheme, boring cutter can be locked in the boring cutter locking device of a position, comprise a recess that is provided with on the operator handle, the upper surface of recess is perpendicular to the operator handle, be positioned at this indent on the operator handle and be provided with screwed hole, one bolt passes the boring cutter handle and through hole is set on it twists and be combined in the screwed hole, the internal diameter of described through hole horizontal direction and bolt external diameter are suitable, the internal diameter of vertical direction is greater than the external diameter of bolt, the upper end of described boring cutter handle has a screwed hole, twist in the screwed hole and closed bolt, described upper end of going up bolt leans the upper surface at recess.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) the utility model operator handle is provided with somely boring cutter, and every that boring cutter is rotated the cutting diameter that forms around central axis is inconsistent, and time processing gets final product the workpiece that the boring pin goes out different apertures like this, and adding does not need tool changing man-hour, has improved production efficiency greatly.
2) the utility model is provided with chamfering blade, and boring cutter has just been realized the chamfering of workpiece simultaneously when boring, thereby has economized the chamfer machining operation one, has improved production efficiency greatly.
3) the utility model can adjust every the distance of boring cutter on central axial direction, thereby can adjust the degree of depth in hole on the workpiece.
Description of drawings

Fig. 3 is for being locked in boring cutter the boring cutter locking device structure schematic diagram of one position
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1, described a kind of multiple-cutting-edge boring cutter is mainly by operator handle 1 and be arranged on boring cutter 2,3 on operator handle 1 perisporium, chamfering blade 4 etc. and constitute.
Be arranged at intervals with boring cutter 2,3 on the perisporium of described operator handle 1 from top to bottom successively, described boring cutter 2,3 is anchored on the operator handle 1 by screw 5, from top to bottom each increases boring cutter successively around the cutting diameter that central axis O-O ' rotates, in other words, the cutting diameter that the cutting diameter that the described boring cutter 2 that is positioned at the lower end rotates around central axis O-O ' rotates around central axis O-O ' less than the described boring cutter 3 that is positioned at the upper end, boring cutter 2 can go out the less size in aperture at the last boring pin of workpiece (workpiece is seen Fig. 2) like this
Boring cutter 3 can process the bigger size in aperture at workpiece
Thereby can process the size in different apertures.
Described boring cutter 6 is anchored on the operator handle 1 by the locking device that boring cutter can be locked in a position, by this device just can make boring cutter 6 along central axis O-O ' the operator handle 1 on, move down, the distance between thereby the adjustment boring cutter is axial, as preferably, the described locking device that boring cutter can be locked in a position comprises a recess 10 that is provided with on the operator handle 1, the upper surface 100 of recess 10 is perpendicular to operator handle 1, be positioned at these recess 10 places on the operator handle 1 and be provided with screwed hole 11, one bolt 9 passes through hole 70 that boring cutter handle 7 is provided with on it and twists and are combined in the screwed hole 11, the internal diameter and bolt 9 external diameters of described through hole 70 horizontal directions are suitable, the internal diameter of vertical direction is greater than the external diameter of bolt 9, like this bolt 9 can be in through hole 70 on, move down, and can not move horizontally, the upper end of described boring cutter handle 7 has a screwed hole, twist in the screwed hole and closed bolt 8, during work, described upper end of going up bolt 8 leans on the upper surface 100 of recess 10, described boring cutter 6 is installed on the boring cutter handle 7 by screw 5, these installation steps that boring cutter can be locked in the locking device of a position are, earlier boring cutter handle 7 is twisted by bolt 9 and be combined in operator handle 1 a certain position, it is fashionable to twist, keep certain degree of tightness, can not overtorquing, bolt 8 is gone up in rotation afterwards, make its upper end lean upper surface 100 at recess 10, again bolt 9 is tightened afterwards, boring cutter handle 7 is fixed tightly on the operator handle 1, in working angles, boring cutter handle 7 is subjected to power upwards, because the upper end of last bolt 8 leans in the upper surface of recess 10, prevents that boring cutter handle 7 from moving up, it is higher to add the man-hour precision, self-evident, according to actual needs, boring cutter 2,3 also can be installed on the operator handle 1 by this device.
Also be provided with chamfering blade 4 on the perisporium of described operator handle 1, the blade of described chamfering blade 4 has angle with the central axis O-O ' of operator handle 1, such structure, boring cutter is when boring, just realized the chamfering of workpiece simultaneously, thereby economized the chamfer machining operation one, improved production efficiency greatly.
