A high-efficiency, small-volume rotary ultrasonic spindle

Abstract

Disclosed is a high-effect and small-size rotary ultrasonic spindle. The high-effect and small-size rotary ultrasonic spindle is composed of an inner ring and outer ring flange-free needle bearing (1), a spring clamping ring (2), a rotary conductive sliding ring (3), an ultrasonic spindle body (4), a ceramic pile (5), a rear cover plate (6), a check ring (7), a deep groove ball bearing (8) and a spring clamping ring (9). The ultrasonic spindle body is supported by the bearings at the front end and the rear end to rotate, the inner ring and outer ring flange-free needle bearing (1) and the rotary conductive sliding ring (3) are arranged at the front end to achieve rotary power supply, the deep groove ball bearing (8) is arranged at the rear end, the ultrasonic spindle body is connected with a rotary spindle of a machine tool or a pneumatic tool in an external hexagon mode or an internal threaded hole mode to provide rotary power, the ceramic pile (5) and the rear cover plate (6) are arranged at the middle end, and a sleeve is adopted on the outer portion of the ultrasonic spindle body (4) for fixing. The high-effect and small-size rotary ultrasonic spindle is compact in structure, the size is minimized, the use range of a traditional machine tool and a pneumatic or electric rotary tool to materials hard to machine is widened, and machining cost is greatly lowered.

Description

Technical field: [0001] The invention relates to a rotary ultrasonic spindle, in particular to a high-efficiency, small-volume rotary ultrasonic spindle. It belongs to the technical field of ultrasonic vibration processing devices. Background technique: [0002] The rotary ultrasonic spindle is a kind of ultrasonic transducer. The ultrasonic transducer is a device that converts electrical energy into ultrasonic energy or ultrasonic waves. It is widely used in lathes, boring machines, milling machines, drilling machines, grinding machines and pneumatic tools in the form of machine tool accessories. Various processing equipment can effectively solve the processability of difficult-to-process materials. However, there are relatively few high-efficiency, miniaturized and high-precision rotary ultrasonic spindle products that can be applied to engineering practice and are suitable for rotary spindle machine tools or pneumatic tools. At present, the ultrasonic machine tool spind...

Problems solved by technology

However, there are relatively few high-efficiency, miniaturized and high-precision rotary ultrasonic spindle products that can be applied to engineering practice and are suitable for rotary spindle machine tools or pneumatic tools.

At present, the ultrasonic machine tool spindles of German DMG Company and Japanese Takesho Co., Ltd. are the most representative abroad, and the price is expensive; domestic research in this area is mostly in the laboratory stage, and there are still some shortcomings, such as: large volume, low output energy, High internal energy loss, serious transducer heating, etc., cannot be widely used in engineering practice
