Vibration reducing supporter of deep hole machining cutter bar

Abstract

The invention relates to a deep hole machine tool, in particular to a cutter bar vibration reducing supporter for the deep hole machine tool, and in particular, discloses a vibration reducing supporter of a deep hole machining cutter bar. The invention solves the problems of complex structure, no reasonability and weak vibration reducing effect in a traditional vibration reducing supporter of deep hole machining cutter bar. The vibration reducing support consists of left and right two parts, wherein the left part comprises a front bearing base, a belt wheel connecting shaft, a large synchronous belt wheel, a thread shaft, a pressure sleeve, a thrust bearing positioning sleeve and a thrust ball bearing; the right part comprises a back bearing base, an inner taper sleeve, a taper block, a taper block and a damping block uniformly distributed with axial wedge gaps, a spring base, a spring and a return ring; and axles of the front bearing base, the belt wheel connecting shaft, the thread shaft, the thrust bearing positioning sleeve, the pressure sleeve, the large synchronous belt wheel, the back bearing base, the inner taper sleeve, the taper block, the damping block, the return spring and the spring base are all positioned on one straight line. The vibration reducing supporter can fully realize the support and the vibration reduction of the deep hole machining cutter bar, is prominent in vibration reducing effect, and greatly improves the machining quality of deep hole parts.

Description

technical field [0001] The invention relates to a deep-hole machine tool, in particular to a cutter bar vibration-damping supporter used on the deep-hole machine tool, in particular to a tool-bar vibration-damping supporter for deep hole processing. Background technique [0002] In the field of mechanical processing, hole processing with a depth / aperture ratio greater than 5 is generally called deep hole processing. In conventional deep hole processing, processing methods such as a deep hole drilling system, a BTA (Boring and Trepanning Association: deep hole processing) system, or an injection system have been used. However, in deep-hole machining, the tool holder is long and has a relatively large major diameter, so it is difficult to perform high-precision deep-hole machining due to bending or buckling of the tool holder, rotational vibration during installation, and the like. After research, it is found that the deep hole drilling system in deep hole processing mainly p...
