Description

A kind of machining cutter

Technical field

The utility model relates to machining tool equipment, particularly a kind of machining cutter.

Background technology

Cutter occupies critical role in Machining Technology for Cutting, the main cutting edge of various cutter and the intersection area of front cutting edge just form the point of a knife of cutter, point of a knife position work under bad environment, thermal capacity is little, easy mill, damaged, be directly connected to machined surface quality again simultaneously, along with the development of Modern Manufacturing Technology, as the processing of various hard-cutting material, hard turning is processed, Precision Machining etc., cutter participate in the various piece of cutting, the proportion that point of a knife subparticipation is cut obviously increases, the impact of wearing and tearing on whole working angles of point of a knife part also increases thereupon, and, existing domestic tool wear is very fast, cause the size of converted products unstable, need frequent replacing, add debug time, reduce production efficiency.

Utility model content

The purpose of this utility model is to provide a kind of machining cutter, to solve the problem proposed in above-mentioned background technology:

For achieving the above object, the utility model provides following technical scheme: a kind of machining cutter, comprise cutter head, knife bar, cutting slot, handle of a knife, first point of a knife and the second point of a knife, described first point of a knife is positioned on cutter head, and the front of the first point of a knife is provided with the first main cutting edge, be provided with the first front cutting edge below, described second point of a knife is positioned on knife bar, and the front of the second point of a knife is provided with the second main cutting edge, be provided with the second front cutting edge below, described first point of a knife is positioned at the top of the second point of a knife, described cutter head is fixedly connected with handle of a knife by knife bar, described cutting slot is positioned at the centre position of knife bar, and afterbody is connected with handle of a knife.

Preferably, described handle of a knife arranges one deck anti-slip veins.

Preferably, described first point of a knife and the second point of a knife are circular arc.

Preferably, described first point of a knife and the second point of a knife are positioned at the side of concentric shafts, and away from concentric shafts.

The beneficial effects of the utility model: this machining cutter is by arranging the first point of a knife and the second point of a knife, can once realize roughing and fine finishining, make the size of converted products and precision more stable, decrease the time of tool changing and debugging, improve the efficiency of production.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of the utility model cutter head;

Fig. 3 is left view of the present utility model.

In figure: 1, cutter head, 2, knife bar, 3, cutting slot, 4, handle of a knife, the 5, first main cutting edge, the 6, first point of a knife, the 7, first front cutting edge, the 8, second main cutting edge, the 9, second point of a knife, the 10, second front cutting edge.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of machining cutter, comprise cutter head 1, knife bar 2, cutting slot 3, handle of a knife 4, first main cutting edge 5, first point of a knife 6, first front cutting edge 7, second main cutting edge 8, second point of a knife 9 and the second front cutting edge 10, first point of a knife 6 is positioned on cutter head 1, and the front of the first point of a knife 6 is provided with the first main cutting edge 5, be provided with the first front cutting edge 7 below, second point of a knife 9 is positioned on knife bar 2, and the front of the second point of a knife 9 is provided with the second main cutting edge 8, be provided with the second front cutting edge 10 below, first point of a knife 6 is positioned at the top of the second point of a knife 9, first point of a knife 6 and the second point of a knife 9 are circular arc, first point of a knife 6 and the second point of a knife 9 are positioned at the side of concentric shafts, and away from concentric shafts, cutter head 1 is fixedly connected with handle of a knife 4 by knife bar 2, handle of a knife 4 is arranged one deck anti-slip veins, cutting slot 3 is positioned at the centre position of knife bar 2, and afterbody is connected with handle of a knife 4.

Operation principle: when using this machining cutter, by handle of a knife 4 by cutter clamping on lathe, by regulating the first point of a knife 6 and the second point of a knife 9 to the position of the workpiece of required processing, the second point of a knife 9 pairs of workpiece are first used to carry out roughing, then in adjustment position, make the first point of a knife 6 pairs of workpiece for further processing, cut and get rid of from cutting slot 3, thus a series of processing effectively completed workpiece, improve the efficiency of producing.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
