Abstract

The invention discloses a workpiece micro shock excitation device and a workpiece micro shock excitation method for vibration machining, in order to solve the problem that no simple and practical workpiece micro shock excitation device or workpiece micro shock excitation method for the vibration machining exists at present. The workpiece micro shock excitation device is characterized in that a servo motor drives an eccentric shaft; an eccentric groove at the bottom of a vibration table is tangent with an eccentric wheel of the eccentric shaft; n pin rollers are equally divided into two groups to be arranged on the two sides of the eccentric shaft; two sliding blocks are arranged on the two sides of the bottom of the vibration table; and the top and the bottom of each sliding block correspond to one group of pin rollers to form a rolling pair. The workpiece micro shock excitation method for the vibration machining comprises the steps as follows: a workpiece is arranged at the top of a three-directional force sensor and clamped by a fixture; the servo motor drives the eccentric shaft to excite the vibration table to vibrate; and a monitoring system monitors and optimizes workpiece vibration cutting, and controls the servo motor to adjust the vibration frequency of the workpiece. According to the workpiece micro shock excitation device and the workpiece micro shock excitation method for the vibration machining, workpiece micro shock excitation machining can be realized efficiently, and the micro displacement vibration frequency and the cutting carrying capacity of the workpiece are monitored, detected and diagnosed in real time.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to workpiece excitation, in particular to a workpiece micro-excitation device and method capable of monitoring vibration and cutting parameters. Background technique [0002] Vibration cutting refers to a cutting method in which a continuous and controllable regular vibration is added to the tool or workpiece during the cutting process to change the processing mechanism. With the continuous development of science and industry, vibration cutting technology has been widely used due to its advantages of reducing cutting force and power consumption, improving production efficiency, improving machining accuracy and surface quality, reducing tool wear and prolonging tool life. Research and Application. Therefore, the development of a workpiece micro-excitation device and method for vibration processing is of great significance for high precision, high efficiency, energy saving and envi...
