Abstract
The utility model discloses a ball end mill with but shake structure, ball end mill use one of the most extensive cutter in the cutting process field. A ball end mill with but shake structure which constitutes and includes: have cutter body (2) but of the structure of shaking, the cutter body in coaxial be provided with cavity (1), the cavity center be fixed with coaxial permanent magnet (3), permanent magnet winding have coil (4), the cavity be full of and have the magnetorheological suspensions body (5). The utility model discloses simple structure, the practicality is strong for milling process.
Description
Technical field
This utility model relates to the technical field of machining tool, and specifically, this utility model relates to a kind of with the rose cutter pressing down structure of shaking.
Background technology
Rose cutter belongs to slotting cutter, due to the performance of its excellence, in machining field, is one of most widely used cutter.But owing to Ball end milling process is the interrupted cut course of processing, when excising rapidoprint, the change of machining condition can cause the sudden change of cutting force, thus cause the vibration of cutter in working angles.That vibrates has had a direct impact machining accuracy and surface roughness, causes processing surface of the work percent ripple phenomenon；Reduce working (machining) efficiency；Make tool wear accelerate, even produce tipping phenomenon, seriously reduce cutter life；Vibration makes the cooperation between each parts of lathe impaired, precise decreasing.
On the other hand, often occurring Flutter Problem in cutting process, tremor is a kind of strong Relative Vibration produced between cutter and workpiece, and Metal Cutting Chatter is a complicated Non-Linear Vibration, it can cause the decline of surface quality, the abrasion of aggravation cutter and generation noise.Tremor limits the raising of working (machining) efficiency, and the course of processing can also be made time serious to cannot be carried out.So the vibration damping problem of rose cutter is just particularly important on lathe.
Traditionally for rose cutter vibration damping problem, most vibration reducing measure is all to carry out improveing or using in the course of processing some skills in technique, and such as to cutter location etc., but this is limited big by operator's experience.Another measure then concentrates on optimization Knife handle structure and machine tool structure, but this oscillation damping method is indirect vibration damping eventually, and damping efficiency glides significantly.Also having a broad aspect is to concentrate on material vibration damping, utilizes material oscillation damping method mainly to use the new material of high intensity to increase cutter quality and Static stiffness to prevent tremor, and rigidity and the biggest Hardmetal materials of intensity enjoy favor.On the one hand this be confined to the excavation of new material and utilize.
Utility model content
The purpose of this utility model is to provide a kind of with pressing down the rose cutter of structure of shaking, and is used for suppressing the vibration of rose cutter during Milling Process, to improve machining accuracy.
Above-mentioned purpose is realized by following technical scheme:
A kind of with the rose cutter pressing down structure of shaking, its composition includes: with pressing down the cutter hub of structure of shaking, being coaxially arranged with cavity in described cutter hub, described chamber central is fixed with coaxial permanent magnet, described permanent magnet is wound with coil, and described cavity is filled with magnetic rheological liquid；
Described cavity is for sealing cavity, and described coil arrangement is under magnetic rheological liquid environment；
Described cavity is in rose cutter knife bar.
Beneficial effect:
The most of the present utility model a kind of with the rose cutter pressing down structure of shaking, being not only suitable for low speed Milling Process, be also applied for high-rate wireless LAN, this structure can suppress to reduce the vibration that rose cutter adds man-hour and produces, improve working (machining) efficiency, improve the surface quality of workpiece to be machined；
Permanent magnet the most of the present utility model, considerably increases the magnetic density in cavity, makes magnetic rheological liquid be under magnetic field environment so that it is to keep both the " active "；
The most of the present utility model a kind of can improve the precision of tool sharpening with pressing down the rose cutter of structure of shaking, extend the life-span of cutter；
Coil electricity current intensity the most of the present utility model is controlled, thus controls the rigidity value of magnetic rheological liquid and the damping force of generation, thus controls inhibition of vibration.
Accompanying drawing illustrates:
Fig. 1 is a kind of overall diagram with the rose cutter pressing down structure of shaking；
Fig. 2 is the B-B sectional view of Fig. 1；
Fig. 3 is the A-A sectional view of Fig. 1；
Wherein, 1-cavity；2-cutter hub；3-permanent magnet；4-coil；5-magnetic rheological liquid.
Detailed description of the invention:
Embodiment 1:
A kind of with the rose cutter pressing down structure of shaking, its composition includes: with pressing down the cutter hub 2 of structure of shaking, being coaxially arranged with cavity 1 in described cutter hub, described chamber central is fixed with coaxial permanent magnet 3, described permanent magnet is wound with coil 4, and described cavity is filled with magnetic rheological liquid 5.
Embodiment 2:
A kind of with pressing down the rose cutter of structure of shaking described in embodiment 1, described cavity is for sealing cavity, and described coil arrangement is under magnetic rheological liquid environment, and described coil electricity, the size of current intensity flow through is controlled.
Embodiment 3:
A kind of with pressing down the rose cutter of structure of shaking described in embodiment 1, described cavity, in rose cutter knife bar, is not related to cutter head.
Embodiment 4:
A kind of with the rose cutter pressing down structure of shaking described in embodiment 1, described magnetic rheological liquid is under the action of a magnetic field, and the rheological property of liquid occurs significantly change, and the viscosity of liquid increases and gradually lacks mobility, when magnetic field intensity arrives certain value greatly, magnetic flow liquid by liquid to solid state transformed.Now, the rigidity of magnetic rheological liquid changes, and produces certain damping force, and this process Rapid reversible, required electric energy is the least, is highly suitable for controlling in real time.So magnetic rheological liquid belongs to controlled fluid, damping change and the stiffness change of device can be realized.
Operation principle:
The specific works process of the present embodiment is as follows: of the present utility model a kind of add man-hour with pressing down the rose cutter of structure of shaking, and along with the vibration of rose cutter, described coil electricity, the size of current intensity flow through is controlled.Variable current produces the change in magnetic field, causes viscosity and the change of density of magnetic rheological liquid in cavity, thus changes the rigidity of magnetic rheological liquid, produce strong damping force, absorbs vibrational energy, the effect reaching to suppress blade vibration with this.
Claims (3)
1. one kind with the rose cutter pressing down structure of shaking, its composition includes: with the cutter hub pressing down structure of shaking, it is characterized in that: in described cutter hub, be coaxially arranged with cavity, described chamber central is fixed with coaxial permanent magnet, described permanent magnet is wound with coil, and described cavity is filled with magnetic rheological liquid.
The most according to claim 1 a kind of with pressing down the rose cutter of structure of shaking, it is characterized in that: described cavity is for sealing cavity, and described coil arrangement is under magnetic rheological liquid environment.
