Abstract

The invention discloses a low-frequency vibration cutting chip breaking device which comprises a shell, a vibration cutting device and a power device. The vibration cutting device includes an amplitude modulation module, a vibration transmission module and a power transmission module. The amplitude modulation module of the device can realize each-degree graded adjustment between 0 degree and 360 degrees by using a double eccentric sleeve combination, a worm and gear mechanism and an angle indicating mechanism, and continuous adjustment of the vibration amplitude within the specified range canbe realized. The device can reliably realize turning chip breaking and can change the vibration amplitude of cutting of a tool, the vibration amplitude adjustment range of the device is 0 to 0.5 mm (graded speed regulation), and adjustment to appropriate parameters can be realized according to actual specific processing requirements. According to the low-frequency vibration cutting chip breaking device, the rotation speed of a motor is changed by a PWM motor governor, the change of the vibration frequency is achieved, and the frequency adjustment range is 25 Hz to 40 Hz.

Description

technical field [0001] The invention belongs to the technical field of vibration cutting, in particular to a chip breaking device for CNC machine tools. Background technique [0002] Vibration cutting is an advanced processing technology developed in the middle of the 20th century, that is, by imposing a certain regular (sinusoidal vibration of a certain frequency and amplitude) and controllable vibration on the cutting tool, the tool and the workpiece are abnormally The continuous contact effect causes periodic changes in cutting speed and back cutting amount, thereby changing its processing mechanism and fundamentally changing the traditional cutting mode. [0003] There are two types of vibration turning: one is ultrasonic vibration cutting with the main purpose of improving machining accuracy and surface roughness, and a high-frequency, small-amplitude vibration tool is used. The other is to break chips as the main purpose. At this time, low-frequency (up to a few hundr...
