Abstract

The invention relates to an external tool bar vibration attenuation mechanism. The external tool bar vibration attenuation mechanism is composed of an adjustable mass cylinder, a compressible elasticring, a fixed mass cylinder, an elastic rubber cylinder and set screws. When the adjustable mass cylinder is adjusted to be screwed into the fixed mass cylinder, the compressible elastic ring compresses the internal elastic rubber cylinder, and thus the effect of adjusting a controllable vibration range is achieved. According to the external tool bar vibration attenuation mechanism, the elastic rubber cylinder is compressed with a small-slope conical surface, and thus the uniformity and controllability of the compression process can be ensured; and besides, the external tool bar vibration attenuation mechanism is simple in overall structure and easy to install and adjust, can be applied to all long and thin tool bars with circular cross sections, can control vibration in multiple directions at the same time, and is high in adjustability and applicability.

Description

technical field [0001] The invention belongs to the technical field of damping and vibration reduction, and in particular relates to an adjustable external cutter bar vibration reduction mechanism. Background technique [0002] During the machining process, the tool performs a severe cutting process on the surface of the workpiece, which generates a large cutting force. If the rigidity of the tool or the workpiece is poor, there will be strong vibration, which will reduce the processing quality and processing efficiency. Therefore, the vibration reduction technology in the processing process has been valued and studied by many engineers and scientific researchers. At present, the commonly used vibration reduction technologies can generally be divided into three categories: active control technology using feedback control energy source, using general energy Source semi-active control technology and passive control technology without energy source input. Among them, passive c...
