Abstract

The invention provides a mechanical torsional vibration table based on a double-eccentric-wheel module. The mechanical torsional vibrator comprises a torsional vibration table surface and two eccentric wheel assemblies. The two eccentric wheel assemblies are respectively located on two sides of the torsional vibration table surface, and are connected with the torsional vibration table surface. Thetwo eccentric wheel assemblies apply homodromous torque to the torsional vibration table surface, and the torque changes in a sinusoidal mode. Torsional vibration with adjustable amplitude and frequency can be superposed to a workpiece in the hole drilling and hole expanding process. The structure is simple, and operation is easy. The mechanical torsional vibration table is suitable for vibrationassisted drilling machining technology. The torsional vibration effect is good, and therefore hole drilling and hole expanding are more accurate. Independent amplitude and frequency adjusting is achieved. The frequency can be adjusted by adjusting the rotating speed of a driving serve motor. The amplitude can be adjusted by adjusting the angle of eccentric subwheels. Convenience, rapidness and stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of machining tools, in particular to a mechanical torsional vibration table based on a double eccentric wheel module. Background technique [0002] In machining, such as turning, drilling, and grinding, axial vibration or torsional vibration of a certain frequency and amplitude is applied to the tool or the workpiece to be processed, which is beneficial to reduce cutting force, reduce sticking, chipping, and reduce cutting. Heat, improve processing progress, improve tool life, and then form a special technology for vibration-assisted processing. According to the frequency of superimposed vibration, it can be divided into ultrasonic vibration-assisted processing and non-ultrasonic vibration-assisted processing. [0003] During the drilling and reaming process of carbon fiber boards, glass fiber boards and other plates, because the fiber materials inside are pulled apart and broken during processing, the proc...
