Description

Shell port burr trimming device of miniature loudspeaker Technical Field The utility model relates to the technical field of loudspeaker production, in particular to a shell port burr trimming device of a miniature loudspeaker. Background The principle of operation of a micro-speaker is electroacoustic conversion. When current passes through the magnet, the magnet generates a magnetic field that acts on the coil on the diaphragm, causing the coil to begin vibrating under the force applied. The vibrating coil drives the vibrating diaphragm, so that the vibrating diaphragm generates sound. Depending on the magnitude and frequency of the current, the vibration speed of the diaphragm will also be different, thereby producing sounds of different tones. When producing the speaker, need carry out burring to the casing port department of speaker and handle, conventional burring device to be inconvenient for placing simultaneously a plurality of speakers to quick adaptability adjustment, whole location operation process is loaded down with trivial details relatively, and is inconvenient for carrying out tip burring to the speaker and polish. Disclosure of utility model The utility model aims at overcoming the defects of the prior art and provides a shell port burr trimming device of a micro-speaker, so as to solve the problems in the prior art. The utility model provides a miniature loudspeaker's casing port burr trimming means, includes the workstation and installs limiting mechanism and the polishing subassembly on the workstation, limiting mechanism includes slide first, screw rod, slide second, bottom plate, limiting plate, spacing portion, connecting plate and locking bolt, slide first is two respectively along two spouts at workstation middle part, screw rod accessible nut is limited on slide first, the bottom plate is installed on the top of screw rod, its both sides pass through slide second is followed the both sides wall spout of workstation and is slided, the limiting plate passes through the pillar and installs on the bottom plate, the spacing portion is a plurality of settings, two a set of opposition slides the hole both sides of placing on the limiting plate, the connecting plate is used for establishing ties a plurality of limiting portions of limiting plate same one side, the locking bolt is used for limiting the connecting plate at the limiting plate side. Through adopting above-mentioned technical scheme, it is spacing to the speaker stability. The polishing assembly comprises a motor and a polishing rod, the motor is arranged on one side wall of the workbench, and the polishing rod is fixedly arranged at the output end of the motor. Through adopting above-mentioned technical scheme, carry out burring to the speaker casing. A pushing plate is further arranged on one side of the bottom plate. Through adopting above-mentioned technical scheme to promote the bottom plate and drive speaker casing and remove, polish the burring through polishing the subassembly. The chute in the middle of the workbench is provided with a through rectangular groove in the middle of the workbench, and the screw is correspondingly arranged with the rectangular groove. By adopting the technical scheme, the bottom plate can move normally. The lower end of the first sliding seat is a sliding plate, the upper end of the first sliding seat is provided with a '匚' shaped structure with a downward opening, the screw longitudinally penetrates through the first sliding seat, and two nuts arranged on the screw are respectively positioned on the upper side and the lower side of the middle section of the upper end of the first sliding seat. Through adopting above-mentioned technical scheme, the height of convenient adjustment speaker casing to the normal processing of polishing assembly is convenient. The shell port burr trimming device of the miniature loudspeaker has the beneficial effects that: The device is convenient to adjust and limit according to the size of the loudspeaker shell, ensures the stability of the loudspeaker shell in the processing process, and simultaneously carries out end deburring treatment on a plurality of loudspeaker shells, thereby improving the treatment efficiency.
