Abstract

The utility model discloses a spiral blade dovetail milling cutter, including the handle of a knife, the one end of handle of a knife is connected with the tool bit through the sword neck, and spiral slot sword has been offered on the surface of tool bit, and the conical blade of spiral slot sword is one section conical spiral, has original straight sword to change spiral blade into dovetail milling cutter's tapering sword, makes it begin to cut consecutively in proper order the work piece from blade line of cutter with some contact in the course of working and makes processing steady, simultaneously because in fact the existence of helical angle has increased cutter work anterior angle to reduce cutting force, effectively must restrain the emergence of shaking the sword phenomenon through cutting in succession, smoothly, avoided workpiece surface's machining defect such as shake knife mark twine, great improvement the roughness on surface of processing.

Description

A kind of helical edges fish-tail cutter
Technical field
This utility model relates to dovetail groove process tool technical field, is specially a kind of helical edges fish-tail cutter.
Background technology
The fish-tail cutter of machinery manufacturing industry application the most both at home and abroad is substantially straight sword frame mode, straight sword fish-tail cutter is fully contacted thus cutting force is big at course of processing cathetus sword and workpiece, easily causes shake cutter phenomenon and the roughness of finished surface is deteriorated;Although cutting ability is slightly improved by the mutation oblique sword dovetail cutter as straight sword dovetail cutter, but shake cutter phenomenon yet suffers from, it is necessary to improve further.
Utility model content
The purpose of this utility model is to provide a kind of helical edges fish-tail cutter, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of helical edges fish-tail cutter, including handle of a knife, one end of handle of a knife is connected by cutter neck cutter head, the surface of cutter head offers spiral grooves sword, and the cone sword of spiral grooves sword is one section of conical spiral.
Preferably, described handle of a knife, cutter neck and cutter head are made of one piece.
Preferably, described handle of a knife, cutter neck and cutter head are connected by welding manner.
Preferably, described spiral grooves sword is that Digit Control Machine Tool processes.
Compared with prior art, the beneficial effects of the utility model are: this helical edges fish-tail cutter, original straight sword there is is to change helical edges into the tapering sword of fish-tail cutter so that it is to start to cut workpiece the most continuously from the cutting edge line of cutter in point cantact mode in the course of processing and make processing steadily;Simultaneously because the existence of helical angle actually increases working orthogonal rake of tool, thus reduce cutting force.By continuously, smoothly cutting effective generation that must inhibit shake cutter phenomenon, it is to avoid the manufacturing deficiencies such as the shake knife mark network of surface of the work, the roughness on the bigger surface that improve processing.By the common effect of two above factor, can be effectively prevented from the course of processing shaking the generation of cutter phenomenon, improve the surface roughness of part to be processed and improve cutting-tool's used life significantly.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 handle of a knife, 2 cutter necks, 3 cutter heads, 4 spiral grooves swords, 5 cone swords.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of technical scheme of this utility model offer: a kind of helical edges fish-tail cutter, including handle of a knife 1, one end of handle of a knife 1 is connected by cutter neck 2 cutter head 3, the surface of cutter head 3 offers spiral grooves sword 4, original straight sword there is is to change helical edges into the tapering sword of fish-tail cutter so that it is to start to cut workpiece the most continuously from the cutting edge line of cutter in point cantact mode in the course of processing and make processing steadily;Simultaneously because the existence of helical angle actually increases working orthogonal rake of tool, thus reduce cutting force.And the cone sword 5 of spiral grooves sword 4 is one section of conical spiral, handle of a knife 1, cutter neck 2 and cutter head 3 are made of one piece, handle of a knife 1, cutter neck 2 and cutter head 3 are connected by welding manner, handle of a knife 1, cutter neck 2 and the setting of cutter head 3 one, the hardness of this milling cutter can be ensured, simultaneously will not produce vibration because of the connection between multiple parts man-hour adding, spiral grooves sword 4 processes for Digit Control Machine Tool.By continuously, smoothly cutting effective generation that must inhibit shake cutter phenomenon, it is to avoid the manufacturing deficiencies such as the shake knife mark network of surface of the work, the roughness on the bigger surface that improve processing.By the common effect of two above factor, can be effectively prevented from the course of processing shaking the generation of cutter phenomenon, improve the surface roughness of part to be processed and improve cutting-tool's used life significantly.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
