Embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment involved in the present invention without limitation, explains technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figures 1 to 8, a kind of Novel tap density meter, comprises slide bar 1, affiliated slide bar 1 top is provided with threaded hole, for fixed amount cylinder base 21, is connected with nylon ball head 18 bottom slide bar 1, nylon ball head 18 bottom is provided with the cam 15 of curved profile, and cam 15 is connected with motor 17; Be provided with keyway outside slide bar 1, keyway has matched wheel disc 7; Cam 15 is coaxially provided with pinion wheel 13, and pinion wheel 13 top is provided with gear wheel 12, and gear wheel 12 is provided with shifting block 23; Shifting block 23 is stirred wheel disc 7 and is rotated.
As shown in Figure 3, graduated cylinder 22 is fixed in graduated cylinder seat 21, and graduated cylinder seat 21 is fixed on volution sleeve column 19 by blind nut 20, and volution sleeve column 19 is fixed by screws on slide bar 1.Motor 17 driving cam 15, because cam 15 has a section, when rotation is through this section, slide bar 1 can fall to producing periodic vibration instantaneously, the graduated cylinder 22 that powder is housed vibrates along with slide bar 1, the jolt ramming gradually of the powder in graduated cylinder 22, and the number of times after vibration that vibration number reaches setting stops, read the volume of powder in graduated cylinder, according to the definition of density; The powder density of quality divided by volume thus after obtaining jolt ramming.Amplitude is 3 millimeters in this example.
Vibration frequency is determined by the rotating speed of motor 17, as long as the invariablenes turning speed of motor 17, vibration frequency is just fixed.
By changing graduated cylinder seat 21, the graduated cylinder of different-diameter can be adapted to.
Driving pinion 13 while motor 17 driving cam 15, pinion wheel 13 drives gear wheel 12, because ratio of gear 1:2, drives gear wheel 12 thus reach the effect of deceleration by pinion wheel 13.
As shown in Figure 8, gear wheel 12 drives shifting block 23, stirs wheel disc 7 and rotates, because wheel disc 7 there are eight wheel disc bars, the rotation transmitted by gear wheel has again the decelerating effect of one-level 1:8.
Slide bar 1 bottom is provided with nylon ball head 18, reduces the friction of cam 15 to slide bar 1 in lifting slide bar 1 process, ensures that Long-Time Service slide bar 1 lift height is consistent.
Guideway 2 and wheel disc 7 slide bar 1 are clearance fit relationship, but the cooperation place between guideway 2 and wheel disc 7 is in the two ends of slide bar 1 respectively, has both reduced the friction of slide bar 1, reduce the swing of slide bar 1 in vibrations process again.
Shifting block 23 stirs wheel disc 7 when rotating, and after shifting block 23 departs from wheel disc 7, affect by inertia factor, wheel disc 7 can continue rotation angle, is head it off, is provided with two elasticity jackscrews 8 at wheel disc 7 excircle, for eliminating the inertia motion of wheel disc.
What the present invention was practically applicable to metal, nonmetal or metal oxide and other compound powders or particle bounces (jolt ramming) density measurement.
Installation method of the present invention: the graduated cylinder that sample is housed is fixed on graduated cylinder seat, and graduated cylinder seat is fixed on slide bar; Cam and pinion wheel are arranged on motor shaft, and motor is arranged on motor cabinet; Wheel disc is arranged on base; Gear wheel is arranged on pinion stand; Under mounted electric machine assembly is arranged on base, its cam center is just to centre hole of base place; Mounted gear wheel assembly is arranged on base side, and size two gears engage just; Mounted graduated cylinder and slide bar assembly are installed in the mounting hole on base.
Basic functional principle of the present invention: motor rotates, band moving cam rotates, and cam promotes slide bar and does upward movement; Camming movement is to otch one rear flank, and slide bar does the movement of falling object under gravity.Motor rotates and drives pinion rotation simultaneously, and pinion wheel drives gear wheel, gear wheel has a driving lever, and driving lever can be stirred wheel disc and rotate, and have slip Flat dey joint between wheel disc and slide bar, wheel disc is with again moving slide-bar to rotate.Thus realize single motor and complete vibration rotary work.
Obviously, above-described embodiment be afterwards only for clearly illustrate institute as citing, and the restriction not to embodiment.For those of ordinary skill in the field, other multi-form change or variations can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And have this apparent change of amplifying out or variation should all belong in protection scope of the present invention.
