Abstract
The utility model discloses a kind of indexable pencil sharper sharp knife, comprise columniform cutter hub, the described cutter hub circle spacing arranges some cutter tooth seats, cutter tooth seat arranges in the shape of a spiral along cutter hub central axis direction, be equipped with chip area between every two cutter tooth seats, each cutter tooth seat is equipped with some separate cutters tooth; Described cutter tooth is indexing type carbide chip, and described indexing type carbide chip is fixed on cutter tooth seat by pinching screw is dismountable.When wearing and tearing appear in the cutting edge that one of them cutter tooth is in operating position, do not need to carry out reconditioning to cutter, only another cutting edge of cutter tooth need be turned to operating position, the size positions precision of cutter is high, and crudy is good.
Description
Technical field
The utility model relates to a kind of wooden pen machining tool, especially a kind of indexable pencil sharper sharp knife.
Background technology
Pencil sharper sharp knife tool in the market generally adopts welding diamond cutter tooth, there is following problem in this pencil sharper sharp knife tool: diamond cutter tooth needs regularly to carry out reconditioning in use, to ensure its crudy, but need cutter hub to unload from equipment axis during reconditioning, due to the change before and after reconditioning of cutter hub position, so cannot ensure the size positions precision of cutter, crudy is poor.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of size positions precision that can ensure cutter, the indexable pencil sharper sharp knife that crudy is good.
To achieve these goals, the utility model have employed following technical scheme:
A kind of indexable pencil sharper sharp knife, comprise columniform cutter hub, the described cutter hub circle spacing arranges some cutter tooth seats, and cutter tooth seat arranges in the shape of a spiral along cutter hub central axis direction, be equipped with chip area between every two cutter tooth seats, each cutter tooth seat is equipped with some separate cutters tooth; Described cutter tooth is indexing type carbide chip, and described indexing type carbide chip is fixed on cutter tooth seat by pinching screw is dismountable.
In the utility model, preferably, described cutter hub is aluminum cutter hub.
Beneficial effect: compared with existing pencil sharper sharp knife, the utility model cutter tooth adopts indexing type carbide chip, indexing type carbide chip is fixed on cutter tooth seat by pinching screw is dismountable, when there are wearing and tearing in the cutting edge that one of them cutter tooth is in operating position, do not need to carry out reconditioning to cutter, only another cutting edge of cutter tooth need be turned to operating position, the size positions precision of cutter is high, and crudy is good; Cutter hub is aluminum cutter hub, thus greatly reduces cutter hub total quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cutter hub; 2-cutter tooth seat; 3-chip area; 4-cutter tooth; 5-pinching screw.
Detailed description of the invention:
Below in conjunction with accompanying drawing the utility model done and further explain.
As shown in Figure 1, indexable pencil sharper sharp knife of the present utility model comprises columniform cutter hub 1, described cutter hub 1 circle spacing arranges some cutter tooth seats 2, cutter tooth seat 2 arranges in the shape of a spiral along cutter hub 1 central axis direction, be equipped with chip area 3 between every two cutter tooth seats 2, each cutter tooth seat 2 be equipped with some separate cutters tooth 4; Described cutter tooth 4 is indexing type carbide chip, and described indexing type carbide chip is fixed on cutter tooth seat 2 by pinching screw 5 is dismountable; In order to reduce the total quality of cutter, described cutter hub 1 is aluminum cutter hub.
When there are wearing and tearing in the cutting edge that one of them cutter tooth 3 is in operating position, do not need to carry out reconditioning to cutter, only the pinching screw 5 fixing this cutter tooth 3 need be unclamped, rotate cutter tooth 3 and make another cutting edge enter operating position, and then cutter tooth 3 added fasten, can work on.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
