Description
Technical field:
This utility model relates to machining tool technical field, refers in particular to a kind of rotatable milling cutter of blade.
Background technology:
Along with the development of Computerized Numerical Control processing technology, the milling cutter as its main process tool develops also very rapid.At present, according to converted products, structure etc., the kind of milling cutter requires that classification is a lot of.Have on the market multiple can more allowing blade replacement or adjust blade position, angle milling cutter, although it can improve the utilization rate of blade to a certain extent, but, it is changed and adjusts and all carries out when off working state, namely when operation, the position of blade remains fixing, simply being adjusted after the blade position of blade is worn again and change, so not only operation is inconvenient for, and affects production efficiency, the overall utilization rate of blade or relatively low, service life is still shorter.
Utility model content:
The purpose of this utility model is the weak point overcoming existing product, it is provided that a kind of rotatable milling cutter of blade.
The technical solution adopted in the utility model is: a kind of rotatable milling cutter of blade, it has a tool tip main body, wherein: form three along the circumferential direction uniform blade positioning seats in the bottom of tool tip main body, along offering a screw with tangentially parallel direction on each blade positioning seat, and it being connected to the threaded mated with screw, the front portion of each threaded is light shaft part and passes screw；It is formed with blade stopper slot between front surface and the rear portion of adjacent knife blades positioning seat of each blade positioning seat, and it is separately installed with blade, each blade entirety is round table-like, each blade includes vane body and blade, offering the through hole corresponding with the light shaft part of threaded on blade, the light shaft part that namely described threaded is anterior penetrates in the through hole of described blade.
The inside of described tool tip main body is hollow form, all offers the first hole that the empty internal with tool tip main body communicates on the sidewall of each blade stopper slot.
Posterior face at each blade positioning seat be further opened with towards adjacent knife blades blade surface and the second hole that empty internal with tool tip main body communicates.
The upper end of described tool tip main body is external screw thread linkage section, forms pair of parallel clamping face on the middle part sidewall of tool tip main body.
This utility model passes through said structure, and blade is movable limit mounting, operationally can rotate freely, so that the utilization rate of whole knife-blade is greatly improved, radiating effect is better, and longer service life, thus reducing the operation and maintenance cost of Milling Process operation；And, the using and change more convenient of this utility model milling cutter.
Accompanying drawing illustrates:
Fig. 1 is the perspective view of this utility model milling cutter.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, this utility model is further illustrated.
As shown in Figure 1, described in the utility model is a kind of rotatable milling cutter of blade, it has a tool tip main body 1, wherein: form three along the circumferential direction uniform blade positioning seats 11 in the bottom of tool tip main body 1, along offering a screw 110 with tangentially parallel direction on each blade positioning seat 11, and it being connected to the threaded 2 mated with screw 110, the front portion of each threaded 2 is light shaft part 21 and passes screw 110；It is formed with blade stopper slot 100 between front surface and the rear portion of adjacent knife blades positioning seat of each blade positioning seat 11, and it is separately installed with blade 3, the thickness of the distance between the width of blade stopper slot 100 and blade positioning seat 11 front surface and front adjacent knife blades positioning seat rear side surface and blade 3 is suitable, make blade 3 just can axial limiting in therebetween；Each blade 3 is overall in round table-like, and each blade 3 includes vane body 31 and blade 32, and blade 3 offers the through hole 30 corresponding with the light shaft part 21 of threaded 2, and namely the light shaft part 21 of described threaded 2 front portion penetrates in the through hole 30 of described blade 3.
During assembling, first blade 3 is put in blade stopper slot 100 so that it is through hole 30 is relative with the screw 110 on blade positioning seat 11, is then tightened by threaded 2 from the outer end of screw 110, make the light shaft part 21 of threaded 2 penetrate in the through hole 30 of blade 3.Pass through said structure, after blade 3 is installed, coordinate the radial direction realizing blade 3 spacing by the light shaft part 21 of threaded 2 and blade 3 through hole 30, and the axial limiting of blade 3 is realized by blade positioning seat 11 front surface of blade 3 itself and the rear side of adjacent knife blades positioning seat 11, make blade 3 spacing in blade stopper slot 100, and owing to the through hole 30 of blade 3 and the light shaft part 21 of threaded 2 are clearance fit, therefore operationally blade 3 can rotate freely around light shaft part 21, this blade 32 all sites allowing for whole blade 3 all can dynamically participate in operation, add the utilization rate of whole blade, and make blade that the time of other position operation can be utilized to dispel the heat in time when operation, thus substantially prolongs the service life of blade, reduce milling cutter maintenance cost.
Further, the inside of described tool tip main body 1 is hollow form, all offers the first hole 101 that the empty internal with tool tip main body 1 communicates on the sidewall of each blade stopper slot 100.The tool tip main body 1 of hollow form is internal can lead to lubricating fluid or coolant, is sprayed by the first hole 101, is directly injected to vane body 31 sidepiece, plays lubrication or cooling effect.
Posterior face at each blade positioning seat 11 be further opened with towards adjacent knife blades 3 blade 32 surface and the second hole 102 that empty internal with tool tip main body 1 communicates.Namely can spray lubricating fluid or coolant from the second hole 102 simultaneously, be directly injected to blade 32 surface, further function as lubrication and accelerate cooling effect, chip can also be blown away better simultaneously.
The upper end of described tool tip main body 1 is external screw thread linkage section 12, forms pair of parallel clamping face 13 on the middle part sidewall of tool tip main body 1.External screw thread linkage section 12 is for connecting handle of a knife, and namely tool tip main body 1 is that detachable is connected with handle of a knife, facilitates replacing and the maintenance of cutter head；And by the clamping face 13 in tool tip main body 1, the instrument such as convenience spanner carries out locking and the fractionation of tool tip main body 1 and handle of a knife.
In sum, this utility model passes through said structure, blade is movable limit mounting, operationally can rotating freely, so that the utilization rate of whole knife-blade is greatly improved, radiating effect is better, longer service life, thus reducing the operation and maintenance cost of Milling Process operation, and, the using and change more convenient of this utility model milling cutter.
