Ultrasonic metal surface machining cutter

Abstract

The invention provides an ultrasonic metal surface machining cutter. The structure of the cutter comprises a cutter head, an amplitude transformer, an amplitude transformer seat, an elastic slice, a pressing block, an oil baffle plate and a pressure or displacement display device. The amplitude transformer is arranged inside the amplitude transformer seat which is connected with the pressing block by the elastic slice, and the amplitude transformer seat is provided with the pressure or displacement display device. The cutter has the following innovations: (1) the contact part between a small end of the amplitude transformer and the tool head is made into conical surface, bevel surface or sphere so as to cause ultrasonic energy output to form a certain angle, thus being capable of machining parts which can not be machined by an ordinary ultrasonic surface machining device; (2) the cutter head is positioned on the amplitude transformer seat by a tool seat adjusting pad; (3) the amplitude transformer seat is internally provided with an oil inlet passage and an oil return passage; and (4) the amplitude transformer seat at the contact part between the small end of the amplitude transformer and the tool head is provided with the oil baffle plate. Compared with the prior art, the ultrasonic metal surface machining cutter can perform ultrasonic machining on revolving body stepped surface with smaller step root distance and size, can machine smaller inner bores, and can perform ultrasonic machining on a plurality of machine tools such as vertical lathes, horizontal lathes, boring lathes and the like in a matching way.

Description

(1) Technical field [0001] The invention relates to a device capable of reducing the surface roughness of the inner hole, outer circle and end surface of a revolving body part, especially the surface of a revolving body part that can process large steps or counterbores and requires a smaller distance from the step root of the part Ultrasonic metal surface machining tools with reduced roughness values. (2) Technical background [0002] At present, the existing ultrasonic metal surface processing tools work by connecting the tool body and the tool head together through threads. The tool head and the tool body are concentrically matched, the working part of the tool head is close to the center of the tool body, and the diameter of the tool body is more than twice the diameter of the tool head, and the size of the tool head protruding from the tool body is limited. The surface of the step-shaped rotary part with a small distance requirement cannot be processed; the smaller inne...
