Abstract
The utility model discloses a cutter for machining step-shaped step holes, comprising a cutter handle, a cutter bit and a cutter blade which is arranged on the cutter bit, wherein the cutter blade comprises a first cutter blade, a second cutter blade and a third cutter blade; the distance between the nose of the first cutter blade and the axis of the cutter handle is less than the distance between the nose of the second cutter blade and the axis of the cutter handle; and the distance between the nose of the second cutter blade and the axis of the cutter handle is less than the distance between the nose of the third cutter blade and the axis of the cutter handle. The cutter is capable of improving the machining efficiency of step-shaped step holes.
Description
Technical field
The utility model relates to metal cutting tool, relates in particular to a kind of cutter that is used to process the stairstepping stepped hole.
Background technology
Cutter is the instrument that is used for the metal parts cut in the machine-building.In machine components processing, run into the processing of endoporus through regular meeting with three sections different-diameters, this hole is actually the stairstepping stepped hole with two steps.At present when processing such stairstepping inner bore of step; The endoporus in each size aperture all need be equipped with a cutter; Just need three the cutter of different size so processing has the hole of three sections different-diameters, and all must repeat identical tool changing clamping action at every turn, thereby cause the working (machining) efficiency of part low; And owing to all to carry out clamping, the inevitable uniformity and the precision that also can influence with batch accessory size to workpiece at every turn.
Summary of the invention
The purpose of the utility model provides a kind of cutter that is used to process the stairstepping stepped hole, to improve the working (machining) efficiency of part stairstepping stepped hole.
The said cutter that is used to process the stairstepping stepped hole of the utility model; The cutter head that comprises handle of a knife, is connected as a single entity with handle of a knife and be installed in the blade on the cutter head; Said blade comprises first blade, second blade and the 3rd blade; First, second, third blade is arranged on the cutter head from cutter head front end to rear end successively; And the distance of first blade point of a knife to the handle of a knife axis is less than the distance of second blade point of a knife to the handle of a knife axis, and the distance of second blade point of a knife to the handle of a knife axis is less than the distance of the 3rd blade point of a knife to handle of a knife axis.
The said cutter of the utility model is owing to be installed in three blades on the cutter simultaneously; So only need just can process stairstepping stepped hole with three sections different-diameters with a cutter; Process time and tool changing clamping times have been reduced; So improved the working (machining) efficiency of part, and avoided because multiple clamping and to the influence of the uniformity and the precision of accessory size.
Description of drawings
Fig. 1 is the said tool structures sketch map that is used to process the stairstepping stepped hole of the utility model.
Specific embodiments
Below in conjunction with accompanying drawing the specific embodiment of the utility model is described:
The cutter head 2 that this cutter that is used to process the stairstepping stepped hole comprises handle of a knife 1, be connected as a single entity with handle of a knife 1 and be installed in the blade on the cutter head 2; Said blade comprises first blade 3, second blade 4 and the 3rd blade 5; First, second, third blade 3,4,5 is arranged on the cutter head 2 from cutter head 2 front ends to rear end successively; And the distance of first blade, 3 points of a knife to handle of a knife 1 axis is less than the distance of second blade, 4 points of a knife to handle of a knife 1 axis, and the distance of second blade, 4 points of a knife to handle of a knife 1 axis is less than the distance of the 3rd blade 5 points of a knife to handle of a knife 1 axis.
