A high-speed and stable tower type boring and milling machining center

Abstract

The invention relates to the technical field of machining, and discloses a high-speed and stable tower-type boring and milling machining center, which includes a base warehouse and a controller. , the top of the central cylinder is fixed with a bearing seat, the bearing seat is rotatably connected with a turntable, the left cutting arm and the right cutting arm are symmetrically arranged on both sides of the turntable, the bearing seat is provided with a rotating mechanism that can drive the turntable to rotate, the left cutting arm and the right cutting arm The area of ​​one end of the arm connected to the turntable is 2-3 times the area of ​​the other end, and the side walls of the left cutting arm and the right cutting arm are variable sections. In this scheme, the variable section is used to make the weight of one end of the left cutting arm and the right cutting arm connected to the turntable greater than the weight of the other end, while ensuring the rigidity of the left cutting arm and the right cutting arm, the center of gravity of the left cutting arm and the right cutting arm is close to the turntable Center, so as to reduce the torque on the rotating mechanism, reduce the internal wear of the rotating mechanism, suppress the frequency of the resonance source, and avoid affecting the processing accuracy.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a high-speed and stable tower type boring and milling machining center. Background technique [0002] With the continuous development of industrialization, the requirements for machining production efficiency of workpieces are getting higher and higher, which puts forward higher new requirements for machining equipment, which not only requires machining equipment with high machining accuracy, but also requires machining The equipment is able to complete the processing of multi-station steps as quickly as possible. Numerical control technology and numerical control equipment are an important foundation for the modernization of the manufacturing industry. The numerical control machine tool is a typical numerical control equipment that uses numerical control technology to improve machining accuracy and efficiency. Its appearance has had a revolutionary impact on the traditional ma...

Problems solved by technology

However, the volume and weight of the machining center required for the processing of large and extra-large parts are relatively large, and when the tool is being processed, its distance from the rotation axis is relatively long, which causes the center of gravity to deviate far from the rotation axis, and the torque on the rotation axis is large. Easy to wear, easy to cause instability in the process of rotation, affecting the machining accuracy
