Description
Technical field
The present invention relates to metalworking technology, relate in particular to the milling cutter of a kind of tape spool to stopping means.
Background technology
As far as milling cutter, the difference of the distance between each cutter tooth and the cutter axial locating surface is called " the axial runout value " of cutter, and the axial runout value of cutter has very big influence to the processing characteristics and the cutter life of cutter; So; Before Milling Process, often to measure the axial runout value of cutter, the axial runout value of cutter is more little; Often mean that machined surface quality is high more, the service life of cutter is long more.In order to reduce the axial runout value of cutter, a lot of cutterheads are designed to the structure that can on axial direction, move with cutter tooth, reduce the axial runout value through the position of cutter tooth on axial direction being adjusted, being controlled.Under high efficiency required, a lot of cutterheads had a lot of numbers of teeth, and in order to satisfy the requirement of axial runout value, wherein a plurality of cutters tooth even whole cutter tooth all will be done the adjustment of axial runout.
Desirable milling cutter is that the minimum point of all cutter tooth all is positioned at " desired cut plane ", and promptly beating is zero.So-called " desired cut plane " is meant the virtual plane apart from cutterhead bottom surface certain distance, is non-existent in reality.In reality,, often adjust beating of cutter through various means in order to obtain less beating; The used instrument of traditional method is that the marble workbench adds a lever meter; Comparatively advanced is to adopt tool setting gauge, but these methods all can only once be proofreaied and correct a cutter tooth, and efficient is very slow.Particularly, to big cutterhead, because cutterhead is very heavy, the number of teeth is a lot, dismantle from lathe, beat to detection, to installing on the lathe, process is very loaded down with trivial details again, and artificial dismounting also brought the tool precision loss, and the production time such as takies at problem.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, provide a kind of simple in structure, cargo handling process is easy and convenient, the tape spool of convenient calibration milling cutter axial runout is to the milling cutter of stopping means.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of tape spool comprises the plate-like tool rest to the milling cutter of stopping means, is distributed in plate-like tool rest periphery, also can makes a plurality of blades that axial location is adjusted around rotary middle spindle C1; And axially stop block; The bottom surface of said plate-like tool rest is inner concavity, and the recess of said bottom surface is provided with spacing convex surface, and the distance that is set to said spacing convex surface is that the plane of H1 is a cutter desired cut plane P 1; Said axially stop block is provided with the location convex surface that is used for said spacing convex surface contact matching; And be used for the accurate face with said a plurality of blade contact matching, and the distance between said spacing convex surface location convex surface and the said accurate face is H2, | H1-H2|≤0.01mm.
Said plate-like tool rest is provided with the centre bore that connects handle of a knife through securing member, and said axially stop block is provided with the mandrel that can cooperate with said centre bore grafting.
Said axially stop block is provided with hollow-out parts.
Said milling cutter also comprises over cap; Said over cap periphery is provided with a circle boss; Said boss is provided with a circle along inner peripheral and is used for the recessed holding part of ccontaining said spacing convex surface, and said spacing convex surface is provided with the concave plane that a circle can closely contact with said boss along outer periphery.
Compared with prior art, the invention has the advantages that:
Tape spool of the present invention is to the milling cutter of stopping means; Axially stop block and plate-like tool rest are accurately located assembling; For the adjustment of the axial location of each blade in esse " desired cut plane " is provided by axially stop block; Promptly through accurately accurately the limiting of axially stop block, thereby effectively reduce the between cog axial runout value of each blade, reach the purpose of the axial runout of adjusting cutter fast, easily in the face of the position of each blade of milling cutter; The calibration operation efficient and the calibration accuracy of milling cutter axial runout have been improved greatly, the processing characteristics and the service life of also having improved cutter simultaneously; This axially stop block is simple in structure, be convenient to dismounting; Can directly on lathe, calibrate cutter; Need whole cutter not unloaded from lathe, save the cutter adjustment time greatly, the clamping error of having brought when having eliminated the cutter dismounting; The loading and unloading wearing and tearing of cutter positioning face have been delayed, the life-span of having improved cutter.On axially stop block, hollow-out parts can be set further, thereby can alleviate the weight of axially stop block, handled easily.Milling cutter of the present invention also can further be provided with over cap; After accomplishing the axial runout calibration, unload axially stop block and load onto over cap, can carry out seal protection to the spacing convex surface on the plate-like tool rest; Pollutants such as spacing convex surface and smear metal are isolated; The spacing convex surface of protection milling cutter is injury-free, when proofreading and correct axial runout once more with further assurance, still can obtain reliable calibration accuracy.
