しながら、従来は、加工における固有の振動に注目した
制振装置を供えたクランプ装置は提案されていない。In a processing machine that cuts and cuts a material with a blade, not only noise but also vibration, which is a cause of the noise, is caused by a roughened processing surface and a significantly shortened life of the blade. It is viewed as a problem. In addition, as described above, as a countermeasure against noise and vibration, a method of shutting off a source with a sound insulating material and a method of reducing noise with a sound absorbing material are used, but workability such as operation of a machine is reduced,
This is a major measure and is often not economically viable. Vibration and noise due to machining are often caused not only by vibration of the blade but also by resonance of the material. In order to suppress noise, it is effective to directly control the material to be processed. However, conventionally, a clamp device provided with a vibration damping device that focuses on vibration inherent in processing has not been proposed.

ものである。[0004] When cutting and cutting a material with a blade, the material is forcibly vibrated by the blade, and vibrations of various frequencies exist due to the forced vibration and the vibration of the entire material or the surface. Has a specific frequency depending on the blade and the material to be processed. An object of the present invention is to provide a clamp device that can suppress vibration and noise during processing by adding a vibration damping device including an elastic plate and a heavy material to a clamp, focusing on vibration inherent in processing. It is assumed that.

The elastic plate is a leaf spring having a predetermined spring constant, and has a predetermined natural frequency with a heavy material. When the spring constant of the leaf spring and the mass of the heavy material are set so as to have a natural frequency close to the natural frequency in cutting and cutting, the material to be cut and the vibration damping unit vibrate simultaneously, and the added weight Since the material is applied to the material to be processed with a force opposite to the vibrating force, the vibrating material cancels the vibrating force generated in the material while vibrating, and as a result, the vibration of the material to be processed is suppressed. become.
