Description

A kind of indexable numerical control mill blade

Technical field：

The utility model is related to machining technology field, has been specifically related to a kind of indexable numerical control mill blade.

Background technology

Milling cutter, is the rotary cutter for Milling Process, with one or more cutters tooth.During work each cutter tooth successively between Cut the surplus of workpiece with having a rest.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece on milling machine Deng.

In the prior art, a kind of milling cutter is disclosed in the Chinese invention patent of Patent No. 201410812365.4, is wrapped A shank is included, its clamping for being used for milling cutter, cutting portion and at least two cell bodies.Cutting portion at least includes two kinds of blades, blade Including one section of continuous curve sword, the starting point of curve sword is being set close to the end of cutting portion.

As can be seen here, milling cutter of the prior art, by including handle of a knife and blade, for the ease of changing different knives Sword, is linked together between blade and handle of a knife by the detachably connected mode such as clamping, this connected mode although Blade can be convenient for changing, but will also result in the milling bits produced during milling and is entered in the gap between handle of a knife and blade, is influenceed The use of handle of a knife and machining accuracy.

Utility model content：

The purpose of this utility model is to provide for a kind of true on the basis of ensureing that handle of a knife can separate replacing with blade Protecting milling bits will not enter in gap, so as to improve the numerical control mill blade of Milling Accuracy.

The purpose is achieved by the following scheme；

A kind of indexable numerical control mill blade, includes handle of a knife, the handle of a knife is solid cylinder, in the side wall of the handle of a knife On opened up neck, the neck can be connected on the tool rest of outside, the fixed cutter on the end face of the handle of a knife, the knife Tool includes connection end and milling end, and the connection end is cylindrical, on the end face for being fixed on the handle of a knife, and the connection end Diameter be less than the end-face diameter of the handle of a knife, opened up installation cavity, milling end one end in the connection end inner hollow It is plugged in the installation cavity, the other end extends outside, extends at the milling end on one end outside and circumferentially offers spiral shell The milling knife of shape is revolved, two Needle bearings are connected between the milling end and the inwall of the installation cavity, in two needle-likes Dust cover is connected between bearing, the dust cover is clamped between the milling end and the inwall of the installation cavity, in institute State and also set up sealing ring between the outer wall at milling end and the end face of the connection end.

Improved as of the present utility model, the bottom land of the neck is a square plane, the two sides cell wall of the neck Just pair and perpendicular to the bottom land.

As it is of the present utility model preferably, the sealing ring be O-ring seal.

Compared with prior art, the utility model has the advantage of：Using anti-between the connection end of cutter and milling end Dust hood is dual dust-proof with O-ring, good dustproof effect, chip can be avoided to enter internal damage internal structure, so as to improve blade Use and machining accuracy.

Brief description of the drawings：

Fig. 1 is the structural representation of indexable CNC milling cutter in the utility model embodiment；

Fig. 2 is Fig. 1 partial sectional view.

Embodiment：

The utility model is elaborated below in conjunction with the accompanying drawings preferred embodiment.

The utility model provides a kind of indexable numerical control mill blade, includes handle of a knife 1, and the handle of a knife is solid cylinder, Neck 2 is opened up on the side wall of handle of a knife, neck can be connected on the tool rest of outside, the bottom land 21 of neck is square flat for one Face, the two sides cell wall 22 of neck is just pair and perpendicular to the bottom land.

The fixed cutter 3 of mode being connected through a screw thread on the end face of handle of a knife, cutter includes connection end 31 and milling End 32, connection end is cylindrical, is fixed on the end face of handle of a knife, and the diameter of connection end is less than the end-face diameter of handle of a knife, even Connect end inner hollow and opened up installation cavity, milling end one end is plugged in the installation cavity, and the other end extends outside, at milling end Extension circumferentially offers spiral helicine milling knife 4 on one end outside, is connected between milling end and the inwall of installation cavity Two Needle bearings 5, are connected to dust cover 6 between two Needle bearings, and dust cover is clamped in milling end and installation cavity Between inwall, O-ring seal 7 is also set up between the outer wall at milling end and the end face of connection end, by the connection end of cutter Dual dust-proof using dust cover and O-ring between milling end, good dustproof effect can avoid what is produced in milling process from cutting Bits enter the internal damage internal structure of cutter, so as to improve use and the machining accuracy of cutter.

It is described above to make preferred embodiment of the present utility model, do not depart from for the person of ordinary skill of the art On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as protection of the present utility model Scope.
