Description

A kind of microphone sealing device

Technical field

The utility model relates to a kind of microphone sealing device.

Background technology

After inner each the parts assembling of microphone finishes, next process seals microphone exactly, seal exactly inner each parts of microphone are closely pressed together in the microphone case, and interior each parts of microphone can not be come off in shell, microphone is when sealing at present, general all is to fix a sealing wheel in the rotating shaft of high-speed drilling machine, rotation by high-speed drilling machine drives the sealing wheel rotation, when the sealing wheel of high speed rotating ran into microphone case, the shell oral area just can be closely pressed together on each parts of microphone in the shell with the form to the shell in-flanges.The weak point of this sealing device is: to seal pressure even in order to reach, edge sealing is smooth, to having relatively high expectations of high-speed drilling machine rotating speed, precision, smoothness and shape need to sealing wheel are very high, and the life cycle of sealing wheel is shorter, to debug, keep in repair sealed in unit at any time, cause production cost and cost of equipment maintenance to improve greatly.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to operate at above-mentioned deficiency, and the low microphone sealing device of maintenance.

For solving the problems of the technologies described above, the design feature of this microphone sealing device is: comprise bearing, the top of bearing is provided with holder, the side wall upper part of holder is provided with two relative slideways at least, slideway is communicated with the outside in the holder, striker is installed in the slideway, and it is flexible along slideway that striker drives the back by the drive unit that is installed in the holder outside.

This microphone sealing device is by striker impact microphone shell, and make shell be produced local deformation by impact site, thereby with microphone each component packages in the enclosure the mode of portion seal, this microphone sealing device is only by bearing, the drive unit that striker and driving striker slide constitutes, structure is very simple, when sealing, earlier be assembled to each parts of microphone in the shell in order, and shell is positioned in the holder of sealing device, just can start drive unit then and drive striker impact microphone shell, for make in the microphone of encapsulation back each parts can compression fit together, before bump in advance in microphone each parts apply a pressure force, make each parts compression fit of microphone together, at this moment each parts aligns the upper surface of high parts in striker needle point and the microphone, like this, when striker impact microphone shell, to under the bump of striker, be caved in of shell to enclosure interior by the bump place, outwards protrude and corresponding shell is inboard with it, this projection just is positioned at each parts of microphone on the upper surface of high parts, like this, when removing when making in the microphone the close-fitting pressure force of each parts, at this moment the effect of shell each parts in projecting inward part has just played the pressing microphone seals end-of-job.In order to improve sealing effect, at least the drive unit that is provided with two relative strikers on the sidewall of holder and is mated, this microphone sealing device greatly reduces the cost and the maintenance cost of equipment to no specific (special) requirements such as speed, fineness, helps to reduce the cost of manufacture of microphone.

A kind of implementation as drive unit, described drive unit comprises the ring-type rotating disk that is sleeved on the bearing outside, rotating disk rotates around bearing by bearing, striker is provided with needle stand near an end of rotating disk, on the striker between needle stand and the holder, be set with spring, be connected with roller on the needle stand, the periphery of roller and the inwall of rotating disk are tangent, are installed with the boss of axial setting on the inwall of rotating disk.

When dial rotation, because roller and rotating disk inwall are tangent, so roller also rotates with rotating disk, like this, roller just has the running orbit of a circle on the rotating disk inwall, and the axial boss and the roller running orbit that are fixed on the rotating disk inwall intersect vertically, when roller runs into boss, the movement locus of roller will change, and roller begins to roll along the outer surface of boss, and this moment, roller promoted needle stand compression spring, and make striker to the holder central slide, like this, striker just begins the impact microphone shell, and microphone is sealed; When roller rolled across boss, spring resiled, the striker playback, and roller still rotates along the rotating disk inwall, repeats said process when roller runs into boss once more.

Carrying out microphone when sealing, for the ease of each parts in the pressing microphone, the bottom of bearing is connected with the pressing frame, on the pressing frame cylinder is installed, and the piston rod and the holder of cylinder are axially aligned.

During use, be installed to each parts of microphone in the shell successively, again microphone is placed in the holder, connect the cylinder source of the gas, piston rod just stretches out cylinder each parts in the shell is closely pressed together on together, rotate rotating disk then and striker bump shell is sealed get final product, operate very simply, help raising to seal efficient.

In order to improve sealing effect, be evenly distributed with four strikers and the drive unit corresponding around the holder with it.

Be evenly distributed with four strikers around the holder, can carry out pressing to microphone case front, rear, left and right four direction, the pressure force that inner each parts of microphone are subjected to is bigger, and sealing is stronger, helps to improve microphone stability in use.

For the ease of operation, the outside of rotating disk is equipped with turning handle.

When carrying out sealing operation, by the promptly rotatable rotating disk of turning handle, thereby drive striker microphone case is clashed into, operate simplyr, a hand just can be operated hommization more.

In sum, adopt the microphone sealing device of this structure, simple in structure, easy to operate, and maintenance is low, is fit to make the microphone that shell does not have flange, can reduce the cost of manufacture of microphone greatly.
