The utility model discloses a kind of NC cutting tool, it comprises chuck and chuck lid, chuck have run through stretch tool bore, chuck lid dismounting be connected to the one end of stretching tool bore; Stackingly in tool bore at least a slice is had along the cutter of its hole wall slippage, to be provided with pre-fault trough at the side opening of cutter stretching; Cutter holding in chuck lid and and the fixing limited block of chuck between; Chuck lid offers out tool bore, and one end of cutter has the blade operative portion through going out tool bore; The groove trend of pre-fault trough is identical with the blade operative portion of cutter.The purpose of this utility model is to provide a kind of after edge wear, and by eliminating pre-fault trough, cutting blade part, namely can reduce the original shape of blade, so that repair blade fast.
Description
Technical field
The utility model relates to a kind of sharpening of cutting edge, and as cutter, and annex, as holding cutter, more particularly, it relates to a kind of NC cutting tool.
Background technology
NC cutting tool is the instrument for machining in machine-building, also known as cutting element.The cutting element of broad sense both comprised cutter, also comprised grinding tool; " NC cutting tool " is except the blade cut simultaneously, also comprises the annex such as knife bar and handle of a knife.
Usual NC cutting tool adopts clip type, is namely be fixed on Digit Control Machine Tool;
Traditional clip type NC cutting tool comprises rotary type and fixed further;
Wherein, fixed NC cutting tool is clamping on the fixture of numerical control vehicle window, carries out chip, polishing by the high-speed rotation of object.
It is in the process of chip, and blade easily occurs wearing and tearing and even damages.
After blade and even edge of a knife fracture, its intrinsic cutting edge shape is destroyed, and is difficult to the shape of being repaired former blade by polishing.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of after edge wear, and by eliminating pre-fault trough, cutting blade part, namely can reduce the original shape of blade, so that repair blade fast.
For achieving the above object, the utility model provides following technical scheme:
A kind of NC cutting tool, it comprises chuck and chuck lid, described chuck have run through stretch tool bore, stretch one end of tool bore described in described chuck lid dismounting is connected to;
Stackingly in tool bore at least a slice is had along the cutter of its hole wall slippage, to be provided with pre-fault trough at the side opening of described cutter described stretching;
Described cutter holding in chuck lid and and the fixing limited block of chuck between;
Described chuck lid offers out tool bore, one end of described cutter have through described go out the blade operative portion of tool bore;
The groove trend of described pre-fault trough is identical with the blade operative portion of described cutter.
Preferably, described limited block has stopper slot, described chuck along stretch tool bore towards offering location groove, described limited block is by through stopper slot with locate the securing member of groove and chuck is fixed.
Preferably, described securing member comprises screw bolt and nut, and the bolt head of described bolt abuts the side of limited block, and its shank of bolt is successively through after stopper slot and location groove, and described nut screws in shank of bolt and is connected to the side of chuck.
Another preferred embodiment, described securing member comprises screw bolt and nut, and the bolt head of described bolt abuts the side of chuck, and its shank of bolt is successively through after location groove and stopper slot, and described nut screws in shank of bolt and is connected to the side of limited block.
In addition, the two sides of described cutter all offer pre-fault trough.
Compared with prior art, blade operative portion of the present utility model is after breaking or occurring scar, directly by pre-fault trough cutting blade operate portions, namely the original state of blade can be recovered fast, now by the burr that the pre-fault trough of simple processing removal stays when disconnecting, the repair of blade namely can be completed fast.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, the utility model NC cutting tool embodiment is described further.
A kind of NC cutting tool 2, comprises chuck 1 and chuck lid 12, offer in chuck 1 run through chuck 1 stretch tool bore, stretching tool bore built with cutter 2; Chuck lid 12 is fixed on the open-mouth stretching tool bore by screw 121, offer on chuck lid 12 simultaneously allow the cutter head of cutter 2 pass go out tool bore; Stretching in tool bore that also slippage has can limited block 3; Cutter 2 is positioned at by limited block 3 and chuck lid 12 and stretches in hole, with in order to process tool 2.
The present embodiment preferably, offers the pre-fault trough 22 that groove trend is identical with the edge of a knife 21 in the two sides of cutter 2; Excessive in the edge of a knife 21 damaged condition, when chip, polishing are all difficult to recover its original shape, by cutting off pre-fault trough 22, the edge of a knife 21 of damage is separated, cut-off part shape is identical with the initial edge of a knife 21 shape simultaneously, the burr that now only needs to polish simply just can use as the edge of a knife 21 again, and it is quick, convenient to repair.
The present embodiment, owing to being clamped in fixture, therefore preferably offering deep gouge 111 in a side of chuck 1, offers location groove in deep gouge 111; Limited block 3 offers stopper slot 31; After cutter 2 is repaired and when reorientating, the bolt head of bolt 41 is connected to the bottom of deep gouge 111, the screw rod of bolt 41 screws in nut 42 through after location groove and stopper slot 31, and nut 42 is directly connected to the sidewall of limited block 3, namely can realize fixing.Simultaneously the bolt head of bolt 41 and bolt 41 bar are all hidden in chuck 1 outer wall, can not have influence on the clamping of the present embodiment and fixture.
In addition, the present embodiment preferably cutter 2 adopts that four cutters 2 are stacking to be formed, and this is because NC cutting tool 2 groove adopts the stiff materials such as wolfram steel, carbide alloy to make.Therefore stacking cutter 2 can be independent, be more prone to cut off by pre-fault trough 22, to reduce reparation difficulty.
The difference of another kind of embodiment of the present utility model is, bolt 41 and nut 42, the bolt head of bolt 41 abuts the side of chuck 1, and its bolt 41 bar is successively through after location groove and stopper slot 31, and nut 42 screws in bolt 41 bar and is connected to the side of limited block 3.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
