An ultrasonic tool head with adjustable gap and directional tool head and its application

Abstract

The invention relates to an ultrasonic tool head with adjustable gap and oriented tool head and its application, comprising a taper sleeve, a tool seat and a tool head, the tool head is installed at the front end of the tool seat, and a cavity for accommodating a horn is arranged in the tool seat The cavity also includes an adjusting nut and a sliding connector. The adjusting nut is threadedly connected to the tapered sleeve. The sliding connecting piece is placed between the adjusting nut and the tool seat for connecting the adjusting nut and the tool seat. The tool seat and the tapered sleeve are connected by a key or pin connection. The tool head of the present invention innovatively introduces the combination of adjusting nuts, spring rings and keys. Through the key guidance, the tool seat only moves up and down without rotating, and avoids when adjusting the gap between the tool head and the horn. The rotation and movement of the tool head causes the problem of uncertain direction, thus eliminating the phenomenon that the cable is damaged or broken due to being entangled. The efficiency of adjusting the gap between the tool head and the horn is improved, the service life of the tool is prolonged, and the waste of resources is reduced.

[0002] Ultrasonic metal surface processing devices have been widely used in industrial production. The existing ultrasonic metal surface processing devices are mainly composed of ultrasonic generators and ultrasonic processing devices. Among them, the ultrasonic processing devices mainly include transducers, horns and tool heads. , the existing tool head generally includes a tool seat, a positioning block and a tool head. The tool head is installed on the tool seat through the positioning block, and the tool seat is threaded with the taper sleeve through the adjusting nut. For example, Chinese patent document CN201648462U discloses an ultrasonic metal The tool head in the surface processing device, the tool head in the processing device, the tool seat and the taper sleeve are connected by threads, so as to realize the adjustment of the gap between the tool head and the horn. During the adjustment process of this structure, the taper sleeve is fixed , the tool seat rotates with the tool head. When the gap is adjusted properly, the direction of the tool head is uncertain. At this time, the gland needs to be loosened, and the direction of the tool head can be adjusted to the direction required for processing by turning the taper sleeve. During the adjustment process, the horn will also rotate accordingly. Since the transducer is connected to the rear end of the horn, and the transducer is connected to the cable, in this way, the cable will rotate along with it during the rotation. As the number of adjustments increases, the cable will become entangled, and the cable will be damaged or broken during the winding process, which will cause the tool to be unusable

At the same time, during the adjustment process, the adjustment is also troublesome. It is necessary to loosen the gland each time, which is less efficient. Sometimes the adjustment is not good once, and it needs to be readjusted many times.

In order to prevent the cable from being entangled or even damaged or broken, it is necessary to overcome the technical difficulty of the uncertain direction of the tool head when adjusting the gap between the tool head and the horn
