(54) УЛЬТРАЗВУКСеОЙ ИНСТРУМЕНТ(54) ULTRASOUND TOOL

II

Изобретение относитс к ультразвуко- вой обработке и может быть использовано в приборостроительной, радиотехнической и других отрасл х прст ышленности дл полировани и обработки деталей резанием .The invention relates to ultrasonic processing and can be used in instrument-making, radio engineering and other industries for polishing and machining parts.

Известны ультразвуковые резцы, имеющие рабочий орган, жестко св занный с волноводом l3 Ultrasonic cutters are known to have a working member rigidly connected to waveguide l3.

Режущее лезвие рабочего органа находитс в посто нном контакте с обрабатываемой поверхностью, что приводит к ее разогреву и затрудн ет отвод тепла. Это обуславливает сравнительно быстрый износ режущей кромки и невысокую стойкость инструмента.The cutting blade of the working body is in constant contact with the treated surface, which leads to its heating and makes it difficult to remove heat. This causes a relatively rapid wear of the cutting edge and low tool life.

Известен также ультразвуковой шаринструмент 2J .The 2J ultrasonic ball tool is also known.

Он имеет небольшую площадь рабочего контакта с обрабатываемой поверхностью и ограниченные усили прижима (дл шара диаметром 10 мм это усилие составл ет 5-8 кг). Увеличение усили прижима затрудн ет вращение тара и приводит .It has a small working area with the work surface and limited clamping forces (for a ball with a diameter of 10 mm, this force is 5-8 kg). Increasing the pressing force impedes the rotation of the container and results.

К снижению его стойкости. Это исключает использование шар а-инструмента дл полировани закаленных деталей, так как при обработке требуетс усшше прижима рабочего органа к обрабатываемой поверхности до кг.To reduce its resistance. This eliminates the use of an a-tool ball for polishing hardened parts, since during processing it is required to hold the tool body against the surface to be treated up to kg.

Применение этого инструмента затруднено дл процесса резани и финишной обработки (например полировани ) поверхностей сложных профилей.The use of this tool is difficult for the process of cutting and finishing (for example, polishing) surfaces of complex profiles.

Цель изобретени - повышение стойкости инструмента и прюизводительности обработки.The purpose of the invention is to increase tool life and processing performance.

Это достигаетс тем, что ультразвуковой инструмент, содержащий волновод, соединенный с концентратором, имеет рабочий орган, вьшолненный в виде кольца , установленного подвижно на торце волновода.This is achieved by the fact that an ultrasonic instrument containing a waveguide connected to a hub has a working body, which is made in the form of a ring that is movably mounted on the waveguide end.

Claims

On . 1 shows an ultrasonic polishing tool; in fig. 2 is the same for cutting} in FIG. An installation of ultrasonic tools, respectively, during polishing and cutting. The polishing tool is made on the basis of a curvilinear waveguide 1 made with a guide ring 2 placed at the end. The tool ring 3 is mounted movably on the guide ring 2 of the waveguide 1 and is fixed axially with the disk 4 fixedly attached to the guide ring. The profile of the tool ring is selected by & depending on the treated surface. Waveguide 1 is connected to a hub (not shown) with a threaded hole 5. When using a cutting tool ring, the working element is made with a round cutting edge and is mounted movably on the conical surface of the curved waveguide 1. Fixing the working body D in the direction of the axis of the curvilinear section The waveguide is made using a nut 6 screwed onto the axis 7 of the Toplita waveguide. When polishing, the tool ring is pressed with the required prescription P to the surface to be machined. The parts skew the rotation V, and the tool axial displacement is 5. The waveguide end is oriented in the machining plane to obtain an acoustic contact of the working body with the waveguide surface. During the polishing process, the ring rotates which creates good conditions for the removal of heat from its working surface and reduces friction in the area of the tool - the surface to be treated. This allows a significant increase in machining productivity while maintaining high tool life. When cutting, the rotating cutter is installed with the front surface orientation perpendicular to the machining plane and turning the water tool around the axis at a certain angle to ensure the rotation of the tool ring around the axis of the waveguide end. The amount of reversal is determined by the cutting modes. Such a rotating ultrasonic cutter provides increased productivity while maintaining high tool life. These advantages are due to the large length of the cutting blade and the best conditions for heat removal and coolant supply. The improvement of the tethozoovod is due to the fact that the cutting edge of the cutting area of the cutting edge of the rotating cutting organ is not subject to heating for a certain time and is cooled in air or with the aid of coolant. The use of the proposed ultrasonic tools by comparison with the known ones allows to increase the processing efficiency by 2-3 times due to the reduction of the machine processing time and to increase the resistance by 3-4 times due to the longer length of the tool working body and good cooling conditions. Claims of the invention Ultrasonic instrument. -Containing waveguide coupled to a hub, and a working body, characterized in that, in order to increase processing performance and tool durability, the working body is made in the form of a ring mounted movably at the waveguide end.
