AI Technical Summary

Technical Problem

The existing boring tools lack effective shock-absorbing structure and precise assembly design, resulting in obvious vibration during processing, affecting the processing accuracy and tool service life, and poor cooling and lubrication function.

Method used

The design includes a shock absorbing structure, assembly assembly and injection assembly. The shock absorbing structure absorbs vibration energy through buffering springs and anti-vibration damping oil. The assembly achieves a stable connection through positioning pins and bolts. The injection assembly sprays coolant to the processing site for cooling and lubrication.

Benefits of technology

It effectively reduces vibration noise, improves machining accuracy and tool life, and at the same time improves cooling and lubrication functions.

Abstract

The invention relates to the technical field of boring tools, and discloses a shockproof and noise-reducing boring tool which comprises a tool body and a tool bit seat, a damping structure is arranged in the tool body, a mounting clamping groove is formed in the surface of the tool bit seat, and a blade is movably clamped in the mounting clamping groove. According to the tool, through the damping structure and the assembling assembly, reliable positioning and locking of the tool bit seat and the tool body are achieved through cooperation of a positioning clamping hole and a telescopic clamping pin, and after an assembling bolt is screwed into a connecting threaded groove through a connecting screw hole, the tool body and the tool bit seat are firmly connected and assembled; shock-proof damping oil and a buffering seat supported by a buffering spring are arranged in the damping cavity, vibration energy from the tool bit seat can be directly borne and absorbed, the vibration energy is converted into elastic potential energy of the spring through deformation, the buffering and damping effects are achieved, the vibration amplitude of the buffering seat is reduced through the damping effect, the vibration energy is further consumed, and the damping effect is enhanced.
