SU432349A1 - ARRATING DEVICE OF RB [FREQUENTLY WEIGHTED BY G'5FO'S S ^: ^^^ "? TOB - Google Patents

Description

The invention relates to the field of weighing technology and can be used in two-dimensional weights of various loads.

There is a known arresting device for lever weights, which contains a double priz.Menoyan yoke with three onopaiMn, two of which are located on both sides of the supporting prism, and a third near the load receiving prism; two horizontally located traverses with stops located on them and moving in a mutually opposite direction almost in a vertical plane, as well as a camshaft. On the lower traverse there is a series of stops to isolate the rocker arm and pendant with an earring, and at the top there is one stop, which, when the upper traverse moves downward, abuts against the support located on the beam near the load-bearing prismo, and bends the beam,. which revolves around two stops that are located on the lower traverse and abut against oiors located on either side of the supporting point (WE, P1 reodoleva with this counterbalance and the earring unit from the load bearing bracket.

The known device due to the inaccurate return of the working blade of the reference prism to its former place on the reference support, as well as due to the presence of elastic hysteresis of the rocker arm with alternating (xc arresting and decelerating cycles has a variation of the optical display readings.

To reduce the variation of the balance in the proposed arresting device, the core is equipped with a racer installed above the load bearing prism and is made with protruding ends of the supporting prism on both sides of the support cushion, which interact with the arresting of the rocker arm respectively through the lever with the abutment and the ends of the angle drop.

FIG. 1 isojura. It is described that the device is in the position of razarretirovanogo bark. in fig. 2 - the same, in the position) 1I is arrested. on fit. 3 - oiorium prism and -pod prnn position disarmed. 1 Coro (Thought; in Fig. 4 - the same, with the position of the arrested rocker.

The device consists of a rocker arm /, and a supporting prism 2 is fixed, swinging on the support bed 3, and a load-receiving prism 4 on which the weight of the load-bearing cushion 5 is pumped, the frame 7 is fixed in the earring 6 and the counterweight 8. Suspension of the drawing pa conventionally not showing .on. On the yoke 9 moving along columns 10, the corner cushion 11 is fixed, the stops 12 and 13. The yoke 9 is moved in a vertical plane by means of cams 14 mounted on the shaft 15. The springs 16 tighten the yoke 9 to the cords 4. On the rack 17, on the base fastened on the scales, the lever 18 is fixed on the axis. The angle at the top of the pad // is greater than the angle of the sharpening of the working blade of the support.

The device works in the following way. When rotated at a certain angle of the shaft / 5, the cams 14 Raise the yoke 9, and the pillow // at the ends of the support prism. 2 lifts the crown, the soap / above the support. Enclosure 3. Simultaneously, the lever 18 fixed in the rack 17 is wrapped under the action the stop 13 and its end presses the frame 7, fixed in the yoke over the load-receiving prism 4. The beam, raised by the corner cushion / / at the ends of the automatic prism 2 under the action of the lever 18, turns around the non-working parts of the blade of the reference prism 2. Ex. and this earring 6 together with the suspension oh sits on stops 12, with The magnetic prism separates from the cargo receiving cushion, and the rock bottom comes to the a-stop position (Fig. 2 and 4).

To unseal the rocker, shaft 15 rotates to turn the cam, and 14, l traverse 9 is lowered. In this case, the stops 12, 13 and the angle of the bottom 11 are lowered.

The lever 18 rises above the frame 7, the yoke / under the action of the counterweight 8 rotates on the angular cushion 11, and the earring 6 with the suspension rests with its cushion 5 on the load-receiving prism 4. With the further lowering of the yoke 9, the support of the prism 2 rests. on a pillow 3. Yoke.

in the uncaged position (Fig. 1 and 3).

Subject invention

An armature weighing device containing a two-prism rocker, supports and located horizontally on the traverse, moving in a vertical plane with the help of jaws sitting on the shaft, characterized in that, in order to reduce the variation of the balance reading, the yoke has a frame, installed over the load-carrying prism, and out of the floor; not with the ends of the support prism protruding but both sides of the support cushion, which interact when locking the rocker arm, respectively, through the lever with the stop l ends of the corner cushion .
