Ultrasonic cutter handle, ultrasonic machining assembly and ultrasonic spindle

Abstract

The invention relates to the technical field of ultrasonic machining, and discloses an ultrasonic cutter handle. A first electric conductor and a second electric conductor are centralized at the rearend of a pull bolt, the portion, making contact with a rotating shaft and electrically connected with the rotating shaft, of the ultrasonic cutter handle can be located in the ultrasonic cutter handleor the rotating shaft and is not exposed in a gap between the ultrasonic cutter handle and the rotating shaft, and therefore the electricity leakage phenomenon can be avoided, and the potential safety hazard is eliminated. Meanwhile, the first electric conductor and the second electric conductor are centralized at the rear end of the pull bolt, and therefore the difficulty of the process that theelectrical connection is formed between the ultrasonic cutter handle and the rotating shaft can be greatly reduced, the stability of the electrical connection between the ultrasonic cutter handle andthe rotating shaft can be improved, and then the effect of the high-frequency vibrating cutting operation of an ultrasonic spindle can be improved. In addition, the invention provides an ultrasonic machining assembly and the ultrasonic spindle which comprises the ultrasonic machining assembly. The ultrasonic machining assembly adopts the ultrasonic cutter handle, and therefore the ultrasonic machining assembly and the ultrasonic spindle have the advantages that the electrical connection is stable, and the cutting machining effect is good.

Description

technical field [0001] The invention relates to the technical field of ultrasonic processing, in particular to an ultrasonic tool holder, an ultrasonic processing component and an ultrasonic spindle. Background technique [0002] Introducing a high-frequency vibration machining mechanism in the process of machining operations can not only improve the surface roughness of the cutting surface and improve machining accuracy, but also reduce cutting resistance and increase the life of the tool, so it is gradually widely used. [0003] The existing ultrasonic spindle is usually composed of a base body, a rotating shaft and an ultrasonic knife handle. The rotating shaft is erected in the base body, and a sleeve hole is provided at the lower end. A power connector is provided in the sleeve hole. The power connector is provided in a thick tubular shape. The first conductive element, and the second conductive element in the shape of a thin tube is insulated in the first conductive el...

AI Technical Summary

Problems solved by technology

[0005] 1. When the insertion part of the ultrasonic tool holder has not been fully inserted into the sleeve and positioned in the sleeve hole of the rotating shaft, since the ultrasonic tool holder still has a positional deviation from the rotating shaft, relatively, the power plug of the ultrasonic tool holder The first and second electrodes and the first and second conductive elements of the power connector have not yet been accurately aligned. Therefore, when the first and second electrodes of the power plug are first inserted into the first and second conductive elements of the power connector, it is easy to cause Damage to the power plug or power connector

[0006] 2. Since the shapes of the second conductive element of the power connector and the second electrode of the power plug are quite tapered, during the insertion process of the second electrode of the power plug and the second conductive element of the power connector, The two must be aligned more precisely. If the position is slightly deviated, the second electrode or the second conductive element is easily damaged due to abrasion or bending
