Vibration test platform for deep hole processing

Abstract

The invention discloses a vibration test platform for deep hole processing, which relates to the field of deep hole processing technology test. The vibration test platform includes a machine tool. A vibration excitation module, an intermediate module and a feed module are installed in turn from left to right on the machine tool. Through the cooperation of the vibration excitation module, the intermediate module and the feed module, any one, two, three or four tests among torsional vibration loading test, axial vibration loading test, radial vibration test and double radial vibration test can be carried out under a combined condition of different rotation states of a drill pipe and a work piece. Therefore, the adjustable range of parameters of the test platform is extended, and the functionality of the test platform is increased.

Description

technical field [0001] The invention relates to the field of deep hole processing technology testing, in particular to a deep hole processing vibration test platform for testing the vibration of a drill rod under the condition that cutting fluid exists inside and outside the drill rod. Background technique [0002] In the deep hole machining system, due to the complexity of the cutting process, the drill pipe is affected by factors such as cutting fluid disturbance, radial vibration, axial vibration and torsional vibration during the cutting process, making it difficult to control the machining accuracy of the drill pipe. It is inevitable to improve the machining accuracy of drill pipes and determine the sequence of factors that affect the sensitivity of drill pipes. However, in actual processing, due to the large volume of workpieces and drill pipes, direct testing will not only lead to serious waste, but also the test conditions are very poor. Therefore, it is imperative t...

[0002] In the deep hole processing system, due to the complexity of the cutting process, the drill pipe is affected by factors such as cutting fluid disturbance, radial vibration, axial vibration and torsional vibration during the cutting process, making it difficult to control the machining accuracy of the drill pipe. It is inevitable to improve the machining accuracy of drill pipes and determine the sequence of factors that affect the sensitivity of drill pipes. However, in actual processing, due to the large volume of workpieces and drill pipes, direct testing will not only lead to serious waste, but also the test conditions are very poor. It is difficult to realize, so it is imperative to build an experimental platform that can dynamically simulate various working conditions in the process of deep hole machining
