Abstract

The utility model belongs to the field of a cutting tool and in particular relates to a split type milling cutter for processing various key-slot type grooves. The milling cutter comprises a cutter handle and a cutter head. The cutter head is arranged at the end part of the cutter handle, the cutter handle is firmly connected with the cutter head by a nut, the cutter head is fixed by a key in the circumferential direction and is axially position-limited by a step, cutter edges are uniformly arranged at the cutter head in the circumferential direction, and the top ends of the cutter edges are circular-arc type. The milling cutter has the advantage that: when the cutter head is broken in the utilizing process, the cutter handle does not need to be replaced, and the cutter head can be directly replaced; the utilization is simple as well as convenient, and the resource cost is saved.

Description

Split type arc shaped groove milling cutter

Technical field

The utility model belongs to the machining field of tool, particularly a kind of split type milling cutter that is used to process various keyway type grooves.

Background technology

Blade shapes has a variety of, plain-milling machine and CNC milling machine working groove and outline of straight line, mills processing cavity on the boring machining center, core, curved surface external form, profile and uses.Used milling cutter is the integral type milling cutter during milling machine working groove of common milling machine and numerical control, cutterhead and handle of a knife are that one processes, such milling cutter in use produces a lot of troubles, when in the cutterhead use, being damaged, can't change, can only be that handle of a knife is more changed together, use cost be very big like this, and its manufacturing cost makes many enterprises hang back on the big basis more.

Goal of the invention

The utility model provides a kind of split type arc shaped groove milling cutter at the high shortcoming of inconvenience of using of use manufacturing cost of above-mentioned technology.

Realize that scheme of the present utility model is as follows:

Split type arc shaped groove milling cutter, it comprises handle of a knife and cutterhead, cutterhead is arranged on the end of handle of a knife, cutterhead and handle of a knife are fastenedly connected by nut, circumferentially fix by key, and be axially spacing by step, described cutterhead circumferentially evenly is provided with blade, and this blade top is a circular arc type.

Described handle of a knife and cutterhead are provided with keyway, and described key is arranged in this keyway.

Utilize the split type arc shaped groove milling cutter of this utility model, it comprises handle of a knife and cutterhead, cutterhead is arranged on the end of handle of a knife, cutterhead and handle of a knife are fastenedly connected by nut, circumferentially fix by key, axially spacing by step, described cutterhead circumferentially evenly is provided with blade, this blade top is a circular arc type, because cutterhead and handle of a knife are split type, therefore the utility model has the advantages that when cutterhead in use is damaged and can need not change handle of a knife, directly change cutterhead, easy to use, save resources costs.

Description of drawings

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

Fig. 2 is the A portion enlarged diagram of Fig. 1;

Among the figure, 1, handle of a knife, 2, cutterhead, 3, nut, 4, blade.

The specific embodiment

As shown in Figure 1 and Figure 2, the split type arc shaped groove milling cutter of the utility model, this milling cutter comprises handle of a knife 1 and cutterhead 2, and cutterhead 2 is arranged on the end of handle of a knife 1, and cutterhead 2 is fastenedly connected by nut 3 with handle of a knife 1, all be processed with keyway on handle of a knife 1 and the cutterhead 2, circumferentially fix by key, handle of a knife 1 end is processed with step, and is axially spacing by step, cutterhead 2 circumferentially evenly is provided with blade 3, and these blade 3 tops are circular arc type.

The utility model is that handle of a knife 1, cutterhead 2, nut 3 splits combine, and therefore in use can in time change, and inconvenient and the high problem of cost are used in the milling cutter processing that has solved handle of a knife and cutterhead integral type.
