Angle-adjustable universal non-resonant elliptical vibration cutting flexible device

Abstract

The invention relates to an angle-adjustable universal non-resonant elliptical vibration cutting flexible device and belongs to the technical field of ultra-precision cutting machining and machining of complex optical parts made from materials difficult to machine. A flexible movement mechanism and a third base are fixed through screws; a cover plate and the base are in butt joint positioning through two square keys; the cover plate is fixed to the base through screws; two round sliding guide rails are formed through butt joint of the base; four sliding supporting feet of the flexible movement mechanism are matched with the round sliding guide rails; angle adjustment is performed through the screws; and the adjustment range is the positive and negative degree. The angle-adjustable universal non-resonant elliptical vibration cutting flexible device is novel in structure and suitable for machining and manufacturing, the movement portion is light in mass, high-frequency vibration of a cutter can be achieved easily, only two piezoelectricity driving is adopted so that control can be easy, a tool rest can achieve both orthogonal cutting and inclined-angle cutting by adjusting the vibration direction of the cutter, and the angle-adjustable universal non-resonant elliptical vibration cutting flexible device is suitable for both a horizontal lathe and a vertical lathe.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision cutting and complex optical parts processing of difficult-to-machine materials, and in particular relates to a universal non-resonance elliptical vibration cutting flexible device with adjustable angle. Background technique [0002] In recent years, vibration cutting has played an important role in the processing of some high-precision parts, especially single-point diamond cutting, which has become an effective processing method for precision and ultra-precision parts, and is widely used in hard and brittle materials. Or the processing of softer materials, not only improves the processing efficiency, but also prolongs the service life of the tool, and obtains better processing quality. Compared with ordinary diamond cutting, the vibration cutting method not only expands the range of materials that diamond tools can process, but also has greater processing flexibility. The current vibrati...

Problems solved by technology

The above four non-resonant two-dimensional elliptical vibration cutting related devices are all single-type orthogonal turning vibration devices, which cannot adjust the tool angle. In actual cutting, it is not limited to orthogonal cutting. The bevel cutting method is also an indispensable processing method in actual production and processing.

Also aiming at the design principle of the present invention, the above-mentioned patent CN 103611947A and patent CN 104117697A adopt two piezoelectric parallel drives, but there are serious coupling phenomena

Therefore, for the elliptical vibration cutting device, although some scholars have carried out R & D and design on it, there are still some deficiencies such as poor universality and serious coupling, which cannot well meet the actual production needs.
