A polishing device for the joint of a spherical sound box shell with a disc sliding structure

Abstract

The invention discloses a polishing device for the joint of a spherical sound box shell with a disc sliding structure, comprising a device body, a support frame is arranged on the device body, a support plate is arranged on the top of the support frame, a fixing frame is arranged above the support plate, and a fixing frame is arranged on the top of the fixing frame A threaded column is set, a rotating rod A and a rotating rod B are arranged on the fixed frame, a supporting top plate is arranged on the device body, a polishing motor is arranged above the supporting top plate, a driven gear is arranged on the end of the rotating rod A arranged on the outside of the fixed frame, and a driven gear is arranged on the device body The power box is equipped with power components inside the power box. The present invention is simple in structure, drives the spherical speaker housing clamped inside the clamping plate to rotate through the circular up and down movement, effectively processes the joints of the spherical speaker housing, avoids burrs protruding, and through the circular power The structure ensures the polishing effect of the joint of the spherical speaker shell, which makes the treatment effect better, easy to use, and strong in practicability.

Description

technical field [0001] The invention relates to the field of sound box production, in particular to a polishing device for the joint of a spherical sound box shell with a disc sliding structure. Background technique [0002] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, responsible for the task of converting electrical signals into acoustic signals for human ears to listen directly to. [0003] The shape of the speaker is square, spherical and irregular. The speaker is generally an injection molded part. After the i...

Problems solved by technology

[0003] The shape of the speaker is square, spherical and irregular. The speaker is generally an injection molded part. After the injection molding is completed, one side of the injection molded part needs to be polished. The connection of the spherical speaker is basically treated by thermal compounding. At this time, its surface It is relatively rough, and its roughness cannot meet the production requirements, so it is necessary to polish the connection. The polishing treatment of the existing spherical speaker connection is generally through manual polishing, because it is inconvenient to control the polishing of the spherical speaker. The work efficiency is relatively low, the precision is low, and the polishing effect is not good, so it needs to be improved
