Damping shock absorber, as well as toolbar and tool with same applied

Abstract

The invention provides a damping shock absorber which comprises an adjusting lever, a mass block, supporting block components and elastomer components, wherein the mass block is arranged outside the adjusting lever in a sleeving manner in a clearance fit manner; the supporting block components are arranged at the two ends of the adjusting lever; the elastomer components are arranged outside the adjusting lever in a sleeving manner and are arranged between the mass block and the corresponding supporting block components; the supporting block components, the elastomer components and the mass block are hermetically connected; and a gap between the mass block and the adjusting lever is filled with damping oil. The invention also provides a toobar and a tool with the damping shock absorber applied. According to the damping shock absorber, the toolbar and the tool, the vibration of the long overhanging tool in cutting is greatly reduced, efficient and stable cutting is realized, the requirements on the processing precision and the roughness of a product are met, the advantages of high stability and high precision are achieved, and particularly the tool is suitable for cutting metal underthe working condition of long overhanging processing.

Description

technical field

[0001] The invention relates to the technical field of cutting, in particular to a damping shock absorber and a cutter bar and a tool using the damping shock absorber. Boring cutting, etc.) for metal cutting. Background technique

[0002] Due to the special functions of deep-processed parts, deep-processed parts often become the key components that determine product quality and efficiency. Due to the uniqueness of large length-to-diameter ratio and multiple interference constraints, deep processing has inherent disadvantages such as poor rigidity system, difficult cooling, and obvious vibration. In addition, the rotation and feeding of the tool in deep processing are accompanied by the pressure of high-pressure cutting fluid. Dynamic load coupling, which leads to frequent bending and torsional vibrations in deep processing, and aggravates the wear of deep processing tools. These working conditions require a long overhang for the tool. At this time, due to i...
