Background technology

In the manufacture process of plant equipment; needs for various location and guiding; adopt some flume structures through regular meeting; because these skewed slots all play location and guide effect usually in plant equipment; so required precision is generally all than higher; for resembling standard series angles such as 45 °, 60 °; can adopt standard cutter to process; but for the non-standard series angle; can only adopt homemade high-speed steel angular milling cutterhead processing,, add passivation easy to wear in man-hour because homemade high-speed steel tool hardness is low; not only efficient is low, and reduces part precision.Therefore the processing and manufacturing for these skewed slots has become technological difficulties.

Summary of the invention

The utility model provides a kind of indexable at any angle carbide-tipped milling cutter dish of processing, and has solved processing skewed slot low precision, inefficient problem in the prior art.

The technical scheme that the utility model adopted is, a kind ofly process indexable at any angle carbide-tipped milling cutter dish, comprise cutter hub, on the cutter hub circumference, evenly be processed with some cutter nests, cutter nest interlaced arrangement, each cutter nest is equipped with an indexable insert tip, throw away tip, and the nose part of all indexable insert tip, throw away tips is on same circumference.

Indexable carbide-tipped milling cutter dish of the present utility model, its feature also be,

The depth dimensions at described cutter nest place equates with the thickness of indexable insert tip, throw away tip, the installation inclined-plane of the indexable insert tip, throw away tip in the cutter nest and be 5 °-20 ° by the angle [alpha] between the diameter of cutter nest bottom; Angle between two inclined-planes of cutter nest bottom equates with the point of a knife angle of indexable insert tip, throw away tip.

The beneficial effects of the utility model are, can be on various milling machines or boring machine the various skewed slots at any angle of Milling Process, this hard alloy rotatable angular milling cutterhead is simple in structure, the skewed slot precision height that processes, and need not whet a knife, improve machining accuracy and efficient.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

As Fig. 1, indexable carbide-tipped milling cutter dish of the present utility model, it is a kind of hard alloy rotatable angular milling cutterhead that on milling machine or boring machine, uses, comprise indexable insert tip, throw away tip 1 and push type broach screw 2 that cutter hub 3, Hardmetal materials are made, cutter hub 3 centers have cutter locating hole 4 are installed, cutter hub 3 is installed locating hole 4 by cutter and is linked together with machine tool chief axis, and during use, the machine tool chief axis rotation drives this angle milling cutter rotating machined workpiece; On cutter hub 3 circumference, evenly be processed with some cutter nests 8 that are used to install indexable insert tip, throw away tip 1, under the prerequisite of indexable insert tip, throw away tip 1 tip of indexable insert tip, throw away tip 1 alignment, cutter nest 8 is by required angle interlaced arrangement, and indexable insert tip, throw away tip 1 is fixed in the cutter nest 8 closing by push type broach screw 2.

Fig. 2 is a cutter hub of the present utility model installation site schematic diagram, Fig. 3 is the cut-away view of the cutter hub among Fig. 2, on the cutter hub 3 P to Q to cutter nest 8 be interspersed, its concrete shape as shown in Figure 4 and Figure 5, the depth dimensions C at cutter hub 3 upper slitter nests 8 places equates with the thickness F of indexable insert tip, throw away tip 1, the installation inclined-plane of the indexable insert tip, throw away tip 1 in the cutter nest 8 and the angle [alpha] of passing through between the cutter nest 8 bottom diameters are selected according to the material of institute's processing parts, the angular range of α is between 5-20 °, if the material of institute's processing parts is the carbon steel of general hardness, angle [alpha] can be selected 10 °, if the material hardness height of institute's processing parts, then angle [alpha] can be selected smallerly, for example can select 5 °, if the material of institute's processing parts is non-ferrous metals such as copper aluminium, then angle [alpha] can be selected greatlyyer, for example can select 15 °.

Fig. 6 is indexable insert tip, throw away tip 1 structural representation of the present utility model, Fig. 7 is the side-looking cut-away view of Fig. 6, the center of indexable insert tip, throw away tip 1 is provided with screw hole 7, the point of a knife angle θ of indexable insert tip, throw away tip 1, indexable insert tip, throw away tip 1 can be made as the case may be especially, the finished product that also can directly select for use specialized factory to make, the matrix material of indexable insert tip, throw away tip 1 and face coat are selected according to the material and the hardness of part to be processed.

Fig. 4 and Fig. 5 be the P of cutter hub of the present utility model to rotation and Q to rotating schematic diagram, the inclined-plane 5, two location of cutter nest bottom is corresponding with two side gradients of indexable insert tip, throw away tip 1, be used for indexable insert tip, throw away tip 1 is positioned, two angles of location between the inclined-plane 5 are γ, and the P that is interspersed is to equaling the point of a knife angle θ of indexable insert tip, throw away tip 1 to the angle γ of cutter nest bottom with Q; The installation inclined-plane at cutter nest 8 tops should be lower than indexable insert tip, throw away tip 1 about 0.5-1mm, interferes with part to be processed in order to avoid add man-hour cutter hub 1; P to Q to the center line of the center line of cutter nest and cutter hub respectively successively left and the angle beta that is tilted to the right, P to Q after the Position Control of cutter nest should make it load onto indexable insert tip, throw away tip 1, indexable insert tip, throw away tip 1 is in the center of circle alignment of cutter outside fillet.So just can obtain and the unequal milling angle of indexable insert tip, throw away tip 1 angle θ ω, as Fig. 8, be the dovetail groove angle schematic diagram of the part that processes.
