Description

Tablet frequency measurement isolation mounting

Technical field

The utility model relates to a kind of device that the sounding component tablet is carried out frequency measurement, particularly a kind of tablet frequency measurement isolation mounting.

Background technology

Tablet on the music box movement is the main sounding component of mechanical type PA-system; Through mill teeth processing slivering dentation sound pin, process through thermal treatment again, require to stir that each root sound pin can both send a distinctive fixed frequency on the tablet; Promptly need the frequency of each root steel sound pin is tested temperament; Make its frequency that reaches standard code,, guarantee the movement psycho-acoustical quality to satisfy the not bent requirement of unisonance.

Patent No. CN200810063513.1 " isolation mounting in the tone board automatic frequency modulation " provides a kind of have been increased between soundboard and sensor by clamping the isolation mounting that cylinder and lever, damping sheet, damping seat constitute; Make the test of soundboard automatic frequency measurement more accurate; But this device only has the vibration isolation function also not have frequency measurement function, function singleness to soundboard.

Summary of the invention

The utility model technical matters to be solved is: a kind of tablet frequency measurement isolation mounting is provided; Can carry out frequency measurement to the sound pin on the tablet; In the tablet frequency measurement; Can prevent the resonance of sound pin on the tested audition pin right sides again, not only measuring accuracy is high, easy to operate, also increases work efficiency greatly.

The utility model addresses the above problem the technical scheme that is adopted: tablet frequency measurement isolation mounting; Comprise power source vertically fixing on the support and the vibration isolating mechanism that laterally is connected; Described power source is an electromagnet, and said vibration isolating mechanism is by the shifting block that is fixed with reseting shrapnel, shell fragment, and shifting block is through being connected with electromagnet with its connecting rod that links into an integrated entity; Also connect the plectrum that rotates around pin on the said shifting block, said plectrum cooperate with reseting shrapnel form.

Compared with prior art, the advantage of the utility model is: this apparatus structure is simple, and part is few; Only by the head that pulls out of electromagnet and band plectrum, shell fragment, reseting shrapnel; Vertical and horizontal are fixed on the support and constitute respectively, and its volume is urinated and processed in installing at small space, and cost of manufacture is low.Not only there is shell fragment can stop tablet to add man-hour on the shifting block in frequency measurement; It is resonated by the sound pin on the acoustic pin right sides, influences measuring accuracy, also has plectrum to carry out frequency measurement to the sound pin on the tablet synchronously simultaneously on the shifting block; This device has frequency measurement, vibration isolation double effects; A tractor serves several purposes is made full use of, also reduced process time simultaneously, improved work efficiency greatly.

Embodiment

Embodiment to the utility model further describes below in conjunction with accompanying drawing.

Connecting rod 7 lower ends are tubular, and there is the rectangle that blind hole, through hole are arranged on opening, the two side upper end for middle, and is as shown in Figure 8.

Waist hole 6-1 is arranged on shifting block 6 one ends, and there is pin hole 6-2 the centre, and plectrum seam 6-3, shell fragment seam 6-4 are arranged in the middle of the other end, the width of seam, highly respectively greater than the thickness of plectrum 2 and shell fragment 1, and the shell fragment seam tilts horizontal by the angle of 10～40 degree, as shown in Figure 7.

Earlier with the upper end of shifting block 6 usefulness pivot pins 5 crosswise fixed at support 9; Also be screwed an end of reseting shrapnel 4 in the upper surface of shifting block; Pass the through hole on shifting block 6 and the plectrum 2 respectively with pin 3, plectrum 2 is connected in the plectrum seam 6-3, plectrum 2 can rotate around pin; Among the tight respectively two shell fragments seam 6-4 that inserts on shifting block 6 one ends of two shell fragments 1, and it is firm to be fixed with cementing agent.

The other end of shifting block 6 inserts in the opening of connecting rod 7 upper ends; Link pin 7-1 passes waist hole 6-1 and blind hole, the through hole on connecting rod 7 two sides on the shifting block respectively; Shifting block 6 and connecting rod 7 are linked into an integrated entity, and the lower end of connecting rod 7 is inserted in the expansion link on the electromagnet 8 and is fixed into one with electromagnet, at last the electromagnet that assembles 8 is screwed on the vertical plane of bearing 9; Tablet 10 is fixed on (figure does not draw) on the processing stations table top, and is as shown in Figure 1.

During use, be illustrated in figure 2 as initial state.When electromagnet 8 energisings, connecting rod 7 up moves under the electromagnetic force effect, meanwhile; The end that the connecting rod band the shifting block that links together with it moves up; At this moment the other end of shifting block 6 just rotates around pivot pin 5 CWs, drives again simultaneously with it fixedly that all-in-one-piece two shell fragments 1 move down, and touches on the tablet 10 by the sound pin 10-1 on the acoustic pin right sides; The front end plectrum head of plectrum 2 also rotates, and is as shown in Figure 3.

Under the continuation effect of electromagnetic force; Shell fragment, plectrum continue to move down with shifting block, at this moment shell fragment be pressed on the tablet plectrum over against by on other sound pin 10-1 on the acoustic pin right sides, it can not be resonated; Influence is made measurement effect more accurate by the frequency measurement of acoustic pin 10-1 '.

Meanwhile, be clamped in two shell fragments, 1 middle plectrum 2 and also rotated around pin 3, go to stir by acoustic pin 10-1 ' by the shifting block drive, to being carried out frequency measurement, as shown in Figure 4 by the acoustic pin.

When shifting block forwards extreme position to, a sound pin is tested simultaneously, and electromagnet 8 is oppositely switched on; Then connecting rod 7 moves down, and an end that drives connected shifting block 6 simultaneously moves down, and the other end of shifting block 6 upwards rotates with regard to counter-clockwise direction; Make shell fragment 1 on it break away from tablet on by the contacting of sound pin 10-1 on the acoustic pin right sides, plectrum runs into measures sound pin 10-1 ', owing to the elastic force of the sound pin 10-1 ' elastic force greater than reseting shrapnel 4; So plectrum clockwise rotates around pin 3, plectrum is rotated get out of the way tablet to its stop, get back to initial position; As shown in Figure 5, plectrum is at the effect of reseting shrapnel 4 rejuvenate beginning state next time then, and is as shown in Figure 2.

Drive tablet 10 by processing stations at last and rotate a position, return to and repeat above-mentioned operation again after the reference position other sound pin on the tablet is processed.

Every sound pin 10-1 on tablet 10 tests.

Therefore device carries out compressing of sound pin and frequency measurement work synchronously, significantly reduces process time, enhances productivity.
