Description
[technical field]
The utility model relates to a kind of workpiece that can pull down from lathe or the clamping of cutter, supporting, and positioner relates in particular to a kind of knife bar of machining.
[background technology]
The cutter that in mechanical processing process, shakes is a kind of extremely harmful phenomenon.If produced the cutter that shakes in the processing, cutter and work package will produce relative displacement, can make finished surface produce oscillation mark, have a strong impact on the surface quality and the performance of part; Process system will continue to bear the effect of dynamic alternate load, and cutter very easily weares and teares, and the lathe connection performance is damaged, when serious even cut can't be proceeded.For reducing vibration, the cutting data of having to sometimes reduce reduces the production efficiency of machine tooling.And in deep-processing process; Vibration has almost become can not also unavoidable problem; Even if every cutter is only cut 0.1mm, also can't stop the generation of vibration, and in order to eliminate the issuable cutter (if this cutter that digs is not eliminated the critical trends that has continuous expansion) that digs of the cutter that shakes; Every processing one cutter will feed be to eliminate relieving amount and to dig tool marks repeatedly under the situation of not feed, and working (machining) efficiency is extremely low.Simultaneously,,, make that the roughness of deep hole is high, cause to gain ultra to cut and scrap owing to digging cutter sometimes so the situation that is difficult to expect all can appear in each processing because vibration is uncontrollable.
Therefore, for common knife bar processing, vibrate to such an extent that can't carry out; Mainly be to use the carbide alloy knife bar instead at present, because the elastic modelling quantity of carbide alloy is bigger, good seismic performance; Can effectively reduce the vibration problem in the process, during still for some cuttings or deep hole machining, the carbide cutter tool vibration of bar has also exceeded the category that allows; Can't satisfy processing request, this just considers other more effectively method of antivibration.
[summary of the invention]
The utility model aims to provide a kind of antivibration knife bar that can reduce the vibration that cutter produces in working angles.
The described antivibration knife bar of the utility model is provided with a cavity in it, be provided with a hollow oscillator coaxial with the antivibration knife bar in the cavity; The two ends of this oscillator are respectively equipped with two all coaxial with antivibration knife bar ring washers, are provided with the damped elasticity support member that is in contact with oscillator, ring washer between oscillator and each ring washer; And link to each other through connector between described two ring washers.
Preferably, described connector is a bolt, and its hollow that is arranged on oscillator is interior and coaxial with the antivibration knife bar, and the two ends of bolt are spirally connected with two ring washers respectively.
More preferably, the two ends of bolt are spirally connected with two ring washers respectively, and wherein the hand of spiral of two ring washers and bolt connecting place is opposite.
The described antivibration knife bar of the utility model can effectively reduce the knife bar vibration problem in the process, thereby improves the working ability of lathe and cutter and improve the workpiece crudy.
[description of drawings]
Fig. 1 is the cutaway view of the utility model preferred embodiment;
Among the figure, 1-cavity, 2-oscillator, 3-ring washer, 4-damped elasticity support member, 5-bolt, 6-screw.
[specific embodiment]
As shown in the figure, the antivibration knife bar of the utility model is provided with a cavity 1 in it, is provided with a hollow oscillator 2 coaxial with the antivibration knife bar in the cavity 1; The two ends of this oscillator 2 are respectively equipped with two all coaxial with antivibration knife bar ring washers 3, are provided with the damped elasticity support member 4 that is in contact with oscillator 2, ring washer 3 between oscillator 2 and each ring washer 3.And link to each other through bolt 5 between described two ring washers 3, described bolt 5 is arranged in the hollow of oscillator 2 and is coaxial with the antivibration knife bar, and the two ends of bolt 5 are spirally connected with two ring washers 3 respectively, and wherein two ring washers 3 are opposite with the hand of spiral of bolt 5 connecting places.
The operation principle of the utility model: analyze with the work of internal lathe-tool bar, can produce cutting force during the point of a knife cutting workpiece, this power makes boring cutter bar produce strain, and after the iron filings on the point of a knife broke, the strain of knife bar was just recovered.Along with the continuous generation of iron filings is broken again, radial cutting force forms sinusoidal fluctuation boring power along with the generation of iron filings and the descending continuous variation of rupturing so.The size and Orientation of this power is clocklike to change always, if the change frequency of cutting force equals or within the intrinsic bullet frequency conversion rate scope of cutter, the boring vibration has just produced.Even knife bar can not produce the bullet change when good knife bar of rigidity such as carbide alloy knife bar can not be guaranteed to cut in fact, in fact blade all trembles when cutting, trembles when still having only bullet to become enough big just to become vibration.Simultaneously, according to the daily life working experience, elastic component is usually used in the mechanical system vibration, and spring, rubber wait vibration damping.For this reason, the utility model is designed to hollow cavity with knife bar, puts into a heavier object (oscillator); Support with elastic component; Made the knife bar that has shock absorber, become vibration, reached and effectively reduce the knife bar vibration thereby reduce the knife bar bullet that causes because of the blade vibration when being implemented in cut.
In use, at first confirm the length that overhangs of knife bar.When producing vibration in the working angles, screw 6 is unclamped, spanner inserting bolt 5 is had an end of plank mouth, rotating bolt 5, make ring washer 3 near or leave, cause 4 compressions of damped elasticity support member or loosen, lock-screw 5 then.Cutting has vibration more again, repeats above-mentioned action, and is minimum until vibration.Thereby can effectively reduce the knife bar vibration problem in the process, thereby improve the working ability of lathe and cutter and improve the workpiece crudy.
