Description
Technical field
The utility model relates to the milling cutter of machining equipment, specifically a kind of ball cutter.
Background technology
Ball cutter is mainly used in cutting circle curved surfaces, for the processing such as surface forming and special-shaped outline, cutting edge of milling cutter in pin process, mainly bottom and bottom periphery position contact with surface of the work, and the top of blade can not contact by surface of the work, edge of milling cutter part is generally made up of materials such as carbide alloy, pottery, cermet, cubic boron nitrides, and cost is higher; Existing milling cutter adopts method of clamping to fix in addition, in order to stability when proof strength and milling cutter work, the external diameter of handle of a knife is identical with the external diameter of blade widest part position substantially, milling cutter is wearing detail, there is unnecessary wasting phenomenon in current this constructed milling cutter, currently be in a high position at raw material, this adds the cost of milling cutter undoubtedly, reduces the cost performance of product; Further, the blade of existing ball cutter is all just located at the surface of cutter head, the cutting edge of formation is more shallow, and quantity is all one group or two groups, can not improve stock-removing efficiency.
Utility model content
For overcoming the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of ball cutter, the cutter head of ball cutter is arranged hemispherical or mushroom construction, the external diameter of milling handle is less than the external diameter of blade widest part position, coordinate special milling fixture, ensureing that milling cutter job stability is with under the prerequisite realizing existing milling cutter repertoire, has saved the energy and raw material, the cost performance of improving product.
For achieving the above object by the following technical solutions:
A kind of ball cutter, comprise cutter head and milling cutter shank, cutter head is provided with blade, it is characterized in that: described cutter head is hemispherical dome structure or umbrella-shaped structure, and the external diameter of described milling cutter shank is less than the external diameter of blade widest part position; The sphere of described cutter head is provided with four scarves, is formed and organize blade more between four adjacent scarves, between each group blade that the bottom of cutter head is corresponding adjacent, have chip area.
The external diameter of described milling cutter shank and the external diameter difference of blade widest part position are 3mm to 20mm.
The utility model is mainly used in Surface Machining according to ball cutter, only has the bottom of blade and bottom periphery and functional contact, thus the blade of ball cutter is arranged to hemispherical dome structure or umbrella-shaped structure, can saves the materials of knife edge part like this during cutting, the utility model is by handle of a knife reduced diameter simultaneously, the external diameter of milling handle is made to be less than the external diameter of blade widest part position, the materials of further saving shank portion, coordinate the milling cutter holder of the custom-designed heating socket join structure of applicant, due to whole, handle of a knife is contained in milling cutter holder, fully can ensure the intensity of milling cutter and the stability of work, and milling cutter shank reduced diameter can make the volume of milling cutter holder less, the utility model is ensureing that milling cutter job stability is with under the prerequisite realizing existing milling cutter repertoire, the energy and raw material are saved, the cost performance of improving product.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model intention;
Fig. 2 is the structural representation that the utility model special-purpose milling cutter holder coordinates.
Detailed description of the invention
As shown in Figure 1, 2, a kind of ball cutter, comprise cutter head 1 and milling cutter shank 2, cutter head is provided with blade, and described cutter head is hemispherical dome structure or umbrella-shaped structure, and the external diameter of described milling cutter shank is less than the external diameter of blade widest part position; The sphere of described cutter head 1 is provided with four scarves 11, forms many group blades 12 between four adjacent scarves, between each group blade 12 that the bottom of cutter head is adjacent, have chip area 13.
Described cutter head 1 is hemispherical dome structure or umbrella-shaped structure, and the external diameter of described milling cutter shank 2 is less than the external diameter of blade widest part position, and both footpath differences are between 3mm to 20mm.
The utility model coordinates special milling cutter holder 3 to implement when using, this special-purpose milling cutter holder 3 adopts heating milling cutter fixed part 31 to be expanded in axial restraint hole, then by the shank portion of milling cutter along for accommodation in axial restraint hole, shrink fixing after cooling, whole milling cutter fixed part 31 is in turbination structure, elongate form, therefore the utility model is by the reduced diameter of milling cutter shank 2, more be conducive to coordinating with milling cutter fixed part 31 and fix, the volume of milling cutter fixed part 31 is made to be unlikely to excessive, ensured stability during intensity and the work of milling cutter by milling cutter fixed part 31 simultaneously, adopt this milling cutter holder 3 to fix simultaneously, milling handle 2 length can shorten, the further saving energy and raw material.
Cutter head 1 is arranged to hemispherical dome structure or umbrella-shaped structure by the utility model in addition, be mainly used in Surface Machining according to ball cutter, the bottom of cutter head and bottom periphery and absorption surface is only had during cutting, and the maximum radius of cutter head add again more than one millimeter not with absorption surface, as long as cutter head structure is arranged the needs that hemispherical dome structure or umbrella-shaped structure can reach processing by us like this; The utility model is provided with four scarves 11 on the sphere of cutter head 1, many group blades 12 are formed between four adjacent scarves, chip area 13 is had between each group blade 12 that the bottom of cutter head is corresponding adjacent, because be provided with scarf, the cutting edge of many groups blade is clearly demarcated, and many group blades can improve the efficiency of cutting; The structure of the utility model cutter head and handle of a knife, under the prerequisite ensureing milling cutter original function, has been saved the energy and raw material, has been reduced cost, improves stock-removing efficiency, thus improves the cost performance of product.
The material of the utility model milling cutter can be carbide alloy, pottery, cermet, cubic boron nitride, or their combination.
