Problems solved by technology

Although the device sets the tool head on the horn, the connection between the tool head and the horn is tightly connected by threads, the tool head cannot be rotated, and the processing efficiency is low and the effect is poor.
[0005] At the same time, the gap between the tool head and the end face of the horn needs to be adjusted when the existing ultrasonic tool is used, and it cannot be used after the gap is changed

Embodiment 1

[0022] Such as figure 1 As shown, the ultrasonic machining tool of this embodiment includes a horn 1 and a tool head 2. The tool head 2 is in the shape of a stepped shaft with small ends and a large middle part. The two ends are positioning parts, and the middle is a processing part. The diameter is smaller than the processing part. The front part of the horn 1 is provided with a positioning installation groove for installing the tool head 2, the structure of the positioning installation groove is adapted to the tool head 2, and the size of the middle part is larger than that of both ends. The tool head 2 is put into the positioning installation groove by the front end of the horn 1, and the bottom edge of the middle processing part is in contact with the horn 1. In this way, when in use, the tool head 2 is always in contact with the horn 1, and there is no need to adjust the gap between the tool head 2 and the horn 1.

[0023] The horn 1 directly drives the intermediate pro...

Embodiment 2

[0025] Such as figure 2 As shown, the difference between the ultrasonic machining tool of this embodiment and Embodiment 1 is that the bottom edge of the positioning part at both ends of the tool head 2 is in contact with the horn 1 , while the middle processing part is not in contact with the horn 1 . The horn 1 drives the middle processing part to vibrate at high frequency through the positioning parts at both ends of the tool head 2, so as to realize ultrasonic processing on the surface of the workpiece.

Embodiment 3

[0027] Such as image 3 As shown, the ultrasonic machining tool in this embodiment includes a horn 1 and a tool head 2 . The front end of the horn 1 is provided with a tool head installation hole perpendicular to the axis of the horn 1, and the tool head installation hole may be a blind hole or a through hole. The side of the tool head mounting hole is provided with a limit pin hole, and a limit pin 3 is installed in the limit pin hole. The tool head 2 is a T-shaped stepped shaft structure, one end is a positioning part, and the other end is a processing part, and the diameter of the positioning part is smaller than that of the processing part. The positioning part is provided with a circumferential limit groove, which realizes the axial positioning of the tool head 2 in the tool head installation hole by cooperating with the limit pin 3, so that the tool head 2 can only rotate but cannot move axially . The processed part of the tool head 2 is outside the mounting hole of t...

Abstract

The invention provides an efficient ultrasonic metal surface machining tool comprising a variable-amplitude bar and a tool head. The tool head is arranged at the front end of the variable-amplitude bar and capable of freely rotating around an axis thereof, and the outermost edge of the tool head protrudes over the surface of the variable-amplitude bar. The tool head is directly arranged in the variable-amplitude bar, so that intermediate junction parts are omitted, the structure is simplified, and overall size is reduced; meanwhile, the tool head can rotate in the variable-amplitude bar flexibly, and the variable-amplitude bar directly transmits ultrasonic vibration to the tool head, so that the drawbacks that a gap between the tool head and the end face of the variable-amplitude bar needs to be adjusted when an existing tool is used and the existing tool is unusable after the gap are changed.

Description

technical field [0001] The invention relates to a tool used for ultrasonic processing on the surface of a metal workpiece, which belongs to the technical field of ultrasonic processing. Background technique [0002] The tool used for ultrasonic machining on the surface of the metal workpiece is usually installed on the ultrasonic metal surface processing device. The ultrasonic machining tool generally consists of a tool seat (or tool seat) and a tool head (or tool head). The horn on the processing device contacts, and the horn vibrates at high frequency under the drive of the transducer, and at the same time transmits the vibration to the tool head, where the ultrasonic machining is performed on the workpiece surface to reduce the roughness value of the workpiece surface. "Ball type cutter head" disclosed in Chinese patent document CN200946158 is mainly composed of a tool holder, a cutter head and a positioning block. One end of the tool holder has a positioning hole for in...
