Abstract

The invention discloses a special tool for quickly notching a horn, which comprises a chassis mould, a rotating mechanism and two cutting tools, the middle part of the rotating mechanism is rotationally fixed on the chassis mould through a rotating shaft, the two cutting tools are respectively arranged at the two ends of the rotating mechanism, and the rotating mechanism drives the cutting tools to rotate so as to realize the cutting of a sectional material; the chassis mould is disc-shaped, one end of the rotating shaft is arranged at the circle center of the chassis mould, and the other endof the rotating shaft is provided with threads; the rotating mechanism comprises a rotating arm and a thrust ball bearing, a through hole sleeving the rotating shaft is formed in the gravity center ofthe rotating arm, and a compression nut is arranged on the rotating shaft; the rotating mechanism is arranged on the chassis mould, the cutting tool is arranged on the rotating mechanism, the rotating mechanism drives the cutting tool to cut a profile placed on the chassis mould, the perforating mode of a through hole is changed, the perforating quality is improved, and the working noise is reduced.

Description

Technical field: [0001] The invention relates to the field of mechanical processing, in particular to a special tooling for horn quick cuts. Background technique: [0002] A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest component in the audio equipment, and it is the most important component for the sound effect. There are many types of speakers, and they vary widely in price. Audio electrical energy produces sound through electromagnetic, piezoelectric or electrostatic effects that cause its cone or diaphragm to vibrate and resonate (resonate) with the surrounding air. [0003] A metal cover (commonly known as a horn) is generally installed on the outside of the speaker. In the actual production process, there is only one small hole at the bottom of the metal cover. When the speaker needs to be installed at the bottom of the metal ...
