ことなく、振動工具からハンドルへの有害振動の伝達を
遮断することができる防監ハンドル装置に関する。[Detailed description of the invention] To be used as a handle of a hand-held vibrating tool such as an electric grinder or an electric drill, and to block the transmission of harmful vibrations from the vibrating tool to the handle without impairing the operability of the handle. This invention relates to a surveillance handle device that allows for security control.

ハンドルの原理及びその問題点について述べる。Conventionally, anti-vibration measures for hand-held vibrating tools such as hand-held electric grinders and electric drills have been achieved by interposing anti-vibration rubber or the like between the vibrating tool and the ndle. 'fr: Many methods are used to insulate. The principle of such a vibration-insulating handle and its problems will be described below.

と振動源１の振幅Ｕとの振幅比４は次のようになる。A vibration-isolated handle can be represented by a mechanical model shown in FIG. In the figure, 1 is the amplitude U,
The vibration source is a vibrating tool that vibrates at an excitation frequency ω and a vibration displacement u'''Usinωt, and between the imager 1 and the mass M...endle 2, there is a viscous resistance coefficient C of the spring 3, which is a spring constant. A damper 4 is provided in parallel.Here, the spring 3 and the damper 4 resemble anti-vibration rubber.At this time,...
If the photographing displacement of the handle 2 is x:=:Xsin (ω is 10α) (X is the amplitude, α is the phase angle), the amplitude of the handle 2 is
The amplitude ratio 4 between the amplitude U of the vibration source 1 and the amplitude U of the vibration source 1 is as follows.

In addition, the curves are those when the natural frequency is ωn2, and here, 4<0.5' is the vibration isolation region, and this is shown by the body line in FIG.

化ヶ要求することから好ましくない。As is clear from FIG. 2, it can be seen that the smaller the natural frequency, the wider the vibration isolation area and the higher the imaging isolation effect. General anti-vibration handles are made based on this idea, but in order to reduce the natural frequency (飄 = ρshi),
It is necessary to weaken the spring 3 or make the handle 2 heavier. However, if the spring 3 is weakened, the operation of the handle 2 becomes softer, and the vibration tool (vibration source 1) becomes unstable, which is dangerous. It is undesirable to make the handle 2 heavy because it requires a lighter weight hand tool in terms of operability.

This is because the vibration isolation area has been expanded, and the photographing 1 insulation effect has been improved.

A spring 9 with a spring constant is vertically interposed between the two. The natural frequency ω of the pendulum 8 of the horizontal pendulum with a spring configured in this way. is expressed as . Therefore, it can be seen that even if the values of m and k are constant, the common frequency of the pendulum 8 changes depending on the value of -, and becomes smaller as the value of 11 increases.

６は振動遮断されたことに外ならない。FIGS. 4(1), CI+), and (1) respectively show the mode shapes of vibration of the pendulum 8 when the vibration table 5 is excited up and down at a frequency exceeding the natural frequency ωn. (r) is when the imaging table 5 is in the neutral position, (II) is when the vibration table 5 is photographed upward, and (1) is the case when the vibration table 5 is photographed downward. Figure 4 shows that due to the effect of the moment of inertia of the pendulum 8, the pendulum 8 has the property of remaining near the neutral position without being affected by external force (the movement of the camera platform 5). . The moment of inertia of the pendulum 8 is ml, and the moment of inertia of the pendulum 8 is increased by the length l. Therefore, at frequencies exceeding the natural frequency ω, Th, the pendulum 8 is maintained in a static state despite the vibration of the vibration table 5. This means that the pendulum 8 and the rod 6 in its vicinity are isolated from the vibrations of the vibration table 5.
