Description
Technical field
The utility model relates to a kind of boring cutter.
Background technology
Crawler belt chain forms primarily of some chain links that head and the tail are hinged, the chain sheet that chain link is oppositely arranged primarily of two, be arranged on the axle between two chain sheet one end and be arranged on the axle sleeve composition between the two chain sheet other ends, chain sheet one end is formed with the first axis hole (aperture) passed for described axle, the other end is formed with the second axis hole (macropore) passed for described axle sleeve, first, the processing of the second axis hole completes on boring machine, for processing the boring cutter of axis hole primarily of knife bar, be arranged on knife bar front end for processing the bore hole blade of axis hole and being arranged in the middle part of knife bar for processing the chamfering blade in dust-proof hole or chamfering structure, the rotation external diameter of its bore hole blade of existing boring cutter cannot adjust, namely the aperture of bore hole cannot adjust, the boring cutter of different model just must be changed in the hole processing different pore size, operation and replacing trouble.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides the boring cutter of the adjustable blade rotation external diameter that a kind of structure is simple, degree of regulation is high.
The purpose of this utility model realizes by following technical solution:
A kind of adjustable blade rotates the boring cutter of external diameter, comprise knife bar, it is characterized in that: also comprise the adjustment tool rest being arranged on knife bar upper end and regulate bore hole blade on tool rest with being arranged on, knife bar is formed with protruding pivot part with the side regulated in tool rest, the opposing party is formed with the pivotable groove suitable with pivot part, the axis of described pivot part and the axis being parallel eccentric setting of described knife bar, described adjustment tool rest can be arranged on described knife bar with rotating adjustment around described pivot part axis, described knife bar is formed with the screw along described pivot part Axis Extension, described adjustment tool rest is formed with the through hole relative with screw, described adjustment tool rest to be locked with described knife bar be connected by being located in screw and the bolt in through hole.
Further, the cross section of described pivot part is circular.
Further, described pivot part is hemispherical.
Further, the upper surface of described knife bar and the lower surface of described adjustment tool rest are horizontal plane, and described pivot part is formed in the upper surface of described knife bar, and described pivotable groove is formed in the lower surface of described adjustment tool rest.
Further, described knife bar is formed with outwardly blade mounting portion, described blade mounting portion is provided with at least one chamfering blade.
Further, described blade mounting portion is provided with two chamfering blades.
The utility model has following beneficial effect:
When needing the rotation external diameter regulating bore hole blade, only need unclamp bolt, then operation regulates tool rest to make it to rotate to an angle around pivot part, the rotation external diameter of bore hole blade is made to reach desired value, then clamping screw, easy to operate, and degree of regulation is high; Be arranged on boring cutter inside by the governor motion regulating tool rest, pivot part, pivotable groove, through hole, bolt and screw to form, do not increase original volume of boring cutter, make the boring cutter of increase governor motion not affect original feeding mode, machining accuracy and performance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is component decomposition map of the present utility model.
Detailed description of the invention
Shown in seeing figures.1.and.2, a kind of adjustable blade rotates the boring cutter of external diameter, comprises knife bar 1, is arranged on the adjustment tool rest 2 of knife bar 1 upper end, is arranged on the chamfering blade 4 regulating bore hole blade 3 on tool rest 2 and be arranged on knife bar 1.
The upper surface of knife bar 1 and the lower surface of adjustment tool rest 2 are horizontal plane, the upper surface of knife bar 1 is formed with protruding hemispherical pivot part 12, tool rest 2 lower surface is regulated to be formed with the suitable pivotable groove 22 of pivot part 12, the axis of pivot part 12 and the axis being parallel eccentric setting of knife bar 1, regulate tool rest 2 can be arranged on knife bar 1 upper surface with rotating adjustment around pivot part 12 axis, knife bar 1 upper surface is formed with the screw 11 along pivot part 12 Axis Extension, regulate on tool rest 2 and be formed with the through hole 21 relative with screw 11, tool rest 2 is regulated to lock with knife bar 1 be connected by being located in screw 11 and the bolt 5 in through hole 21.
When needing the rotation external diameter regulating bore hole blade 3, only need unclamp bolt 5, then operation regulates tool rest 2 to make it to rotate to an angle around pivot part 12, makes the rotation external diameter of bore hole blade 3 reach desired value, then clamping screw 5.
The above, be only preferred embodiment of the present utility model, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
