Description

Antihunting device

Technical field

The present invention relates to decay or the suppression field of vibration, particularly, one is applied and is being rotated or do not rotating thing The antihunting device of part.

Background technology

Vibration and the life of the mankind, closely bound up, the most melodious music, or annoying noise, all It is the one of vibration concrete manifestation.

The object that human lives uses or touches, the shell of such as washing machine or motor are motionless, motor Rotor or dehydration cylinder are to rotate.And for example in some cutting operations, workpiece is to rotate, and cutting tool is not Rotate；At some cutting operation, workpiece does not rotates, and cutting tool is to rotate.

Accordingly, it is capable to the conversion between dynamic element and motionless element, the physics easily producing vibration is existing As.The characteristic of vibration can be explained with frequency and amplitude.The number of times vibrated back and forth per second, the frequency of meaning, The size of vibratory output, referred to as amplitude.The natural frequency once vibrated is same as the frequency of environmental stimuli, will There is resonant interaction, cause the inefficacy of excessive deformation and system, frame for movement is caused serious impact.

For the decay vibrated or suppression, the birth having amortisseur (Damper) of beginning.Amortisseur can be installed On motionless object, such as positions such as the beam of building, posts, in order to decay or to suppress earthquake to building Frequency of vibration and amplitude.Amortisseur also can be arranged on dynamic object, and such as the cutter of purposes of holing, reduction is cut Cut the electric shock of instrument.

The patent documentation of amortisseur is used at cutting element, too numerous to enumerate, such as Japanese Unexamined Patent Publication 2001-96403 Number, No. 2003-62703, No. 2003-136301, No. 2005-177973, or Unexamined Patent 6-31505 Number, No. 6-31507, or special permission publication such as No. 2979823.It addition, the U.S. the 8th, 371,776 is special Profit case discloses the correlation technique content using amortisseur equally.

Summary of the invention

It is an object of the invention to: a kind of centering type vibration-proof structure is provided, use at the dynamic or motionless thing of majority On part, it is used for decaying or suppressing frequency and the amplitude of vibration.

Reaching because of above-mentioned purpose, a kind of antihunting device of the present invention, it is characterised in that including:

Detailed description of the invention

Refer to Fig. 1, Fig. 2, illustrate the specific configuration of a preferred embodiment of antihunting device 100.Vibrationproof fills Put 100 to be made up of main body 10, two lid 20 and two damper units 30.Main body 10 to be internally formed two inclined Ventricle 12.The volume of eccentric room 12 is more than the volume of damper unit 30.Damper unit 30 inserts eccentric room After 12, seal eccentric room 12 with lid 20, stop damper unit 30 to leave main body 10.

Main body 10 is round.As shown in Figure 4, diametrically one end from main body 10 is cutd open toward the other end Opening, the wall of each eccentric room 12 includes heavy section 14 and a thinner wall section 16.Heavy section 14 is in thinner wall section 16 opposites, its with adjacent eccentric room 12 heavy section 14 not with.

Stated in an another way, the shape of the section of main body 10 is about rectangle, and it has two groups of diagonal angles 15, in often group Standardized bar diagonal 13 between diagonal angle 15, two crossing points of diagonal 13 are considered as a symmetrical centre 11.Right Title center 11 is not only located at diagonal 13 central authorities, is split into two halves by diagonal 13, the most also falls and leads at one On the axis 17 of two ends crossing main body 10.Because after main body 10 rotates 180 ° around symmetrical centre 11, two The heavy section 14 of eccentric room 12 coincides, completely so the internal structure of main body 10 is generally with symmetrical centre 11 is symmetrical for reference point.

In the present embodiment, the outer circumference surface of main body 10 forms a guide unit 40, and guide unit 40 is by one Circular rabbet 42 hinders into two straight recesses 44.Circular rabbet 42 referred to herein, refers to the cylindrical around main body 10 The groove of side face, circular rabbet 42 is between two straight recesses 44.Straight recess 44 referred to herein, refers to suitable Axis 17 direction and be trapped in the straight trough of main body 10 appearance, straight recess 44 is positioned at heavy section with eccentric room 12 The both sides of 14, its one end communicates with circular rabbet 42, and the other end goes directly the end face of main body 10.

It is assumed that antihunting device 100 is arranged on cutting element (drawing is not painted), guide unit 40 can guide Coolant flow to the position that workpiece (drawing is not painted) is cut, and reaches cooling and washes away the function of chip.? Some embodiment, the inessential structure of guide unit 40, optionally removing need not.

In the present embodiment, this damper unit 30 is stud, and its appearance forms one section of external screw thread 32, and is subtracting Unit 30 end that shakes forms a drive division 34.In figure, drive division 34 is straight groove, in order to accommodate a work Tool, such as screwdriver.Damper unit 30 is driven to enter the eccentric room 12 of main body 10 spirally with screwdriver, External screw thread 32 is made to engage one section of female thread 18 around eccentric room 12.

Because inside and outside thread also exists spacing, add that damper unit 30 volume is less than eccentric room 12 volume Reason, makes damper unit 30 maintain a certain distance with the eccentric room 12 of main body 10.So, damper unit The axis of 30 is equivalent to line of eccentricity 19, as described axis 17 at intervals.

Each lid 20 welds together with main body 10, and damper unit 30 is produced barrier effect, it is to avoid its Eccentric room 12 is left without early warning.

From the point of view of Fig. 3～Fig. 5, main body 10 stress produces certain vibration, damper unit 30 according to inertia to master The vibration of main body 10 is offset or weakened to body 10, around the wall force of eccentric room 12,.Especially, two vibration damping list The line of eccentricity 19 of unit 30 is positioned at the both sides of axis 17, and the vibration contributing to main body 10 is supported by damper unit 30 Disappear or weaken.

It should be noted that damper unit 30 has two elastomers 36, each elastomer 36 is annular design, Tighten in damper unit 30 outside, and adjoin with external screw thread 32 front end or rear end.Elastomer 36 and main body 10 Female thread 18 keep contact relation, contact position to be probably the tooth paddy of female thread 18, it is also possible to be crest.

During main body 10 is vibrated, damper unit 30 according to inertia along diametric(al) and the axis 17 of main body 10 Direction moves back and forth.So, elastomer 36 is extruded generation by the damper unit 30 towards female thread 18 displacement Deformation, the active force (or claiming elastic force) needed for savings reinstatement.Once damper unit 30 is away from main body The female thread 18 of 10, elastomer 36 discharges elastic acting force and reinstatement, promotes damper unit 30 to accelerate Mobile, it is more beneficial for offsetting or weakening the vibration of main body 10.
