Abstract

THE LOADING SYSTEM OF A FORCE NORMAL MEASURING DEVICE INFLUENCES ESSENTIALLY IMPORTANT PARAMETERS WHEN CHECKING AND OAKING OF FORCE MEASURING DEVICES. THE INVESTIGATION CONCERNS A LOADING SYSTEM IN WHICH THE MEASUREMENT (1) IS SUBJECTED BY THE FACT THAT ON THE LOADING PROCESS OF AN ADDITIONAL HEADING DEVICE (3) AND CORRESPONDING SHUTTERS, ONLY THE FIRST AND THEN FIRST MEASUREMENT OF A MASSSTUECKSTAPLEL IS DIRECTLY RELATED TO THE LEVEL (5) OF FIXED NORMAL MEASURING EQUIPMENT, ALL OTHER MEASURES, BUT ON CERTAIN CONSTRUCTION ELEMENTS (7), SHOULD BE POSTPONED TO THE FIRST THICKNESS. THIS TYPE OF LOADING SYSTEM MAY, IN A SIMPLE CONSTRUCTIVE CONSTRUCTION, ALLOW ANY SERIES OF MEASURING RULES TO AVOID UNBALANCED INTERMEDIATE BREAKING TREATMENTS HAVING THE SAME TIME DISTANCE BETWEEN INDIVIDUAL FUEL TREES, INDEPENDENT OF THEIR SIZE. MOREOVER, THE MEASUREMENT OF THE FORCE OF THE FORCE NORMAL MEASUREMENT DEVICE CAN BE REDUCED SO FAR THAT A MAJOR RANGE OF MEASUREMENTS WILL BE POSSIBLE WITHOUT THE USE OF A DIVERSING DEVICE.

Load system of a force Eo in aimeßeinrichtung for testing or calibrating force gauges

Field of application of the invention

The invention relates to the system for generating power at Eraftmeßeinrichtungen, in particular force ITormalmeßeinrichtungen, by means of specially arranged ,, in a special way with the hanger of the force-Hormalmeßainrichtung and to be connected to each other mass pieces · ...

Characteristic of the known technical solutions

There are force-Normalmeßeinrichtungen known in which arranged in different ways Massestiicke are stored in each case the same .vorgegebener sequence by the vertical process of the hanger or the Massestückabsetzgerüstes the force-Hormalmeßeinrichtung on the hanger and so serve for power generation (Kraft-iTormalmeinrichtungenseinrichtung with chain hanger )

The load cycle time depends on the size of the power level. Intermediate, unnecessary power levels are also generated. The structural design of these Kraft iTormalmeßeinrichtungen is relatively simple.

Furthermore, force-Formaimeßeinrichtungen are known in which the masses usually combined in several stacks can be moved independently and stored on the hanger. Thus, series of measurements are possible without generation of sixty-two different degrees of force required.

time is correspondingly short, but usually not zv / ischen each load level completely the same.

In their Belastungssy star sind.deste force-Eormalmeßeinrichtungen relatively expensive designed ο

Also known are force-lormalmeßeinrichtungen with mechanical or hydraulic force stabilizers, where more power levels can be generated than mass pieces are available.

However, the stress 2: 7 relaxation time is relatively large in these force-hormone measuring devices.

Since the measuring range of a force-iFormalmeßeinrichtung in addition to the number of available pieces of mass also depends on the suspension mass taring devices can be used, which serve for taring the Gehängeiaasse, which, however, additional error influences by friction u. a. are unavoidable »

Object of the invention

The aim of the invention is the load system of a force-normal measuring device, which is simple in construction, permits and does not require measurement series with a short load cycle time, which is as equal as possible and independent of the magnitude of the force to be generated between the force stages Intermediate loads up to the selected power level excludes.

Furthermore, the largest possible measuring range is to be achieved by a substantial reduction of the suspension mass (first power level).

Explanation of the essence of the invention

The stress on force-measuring devices of conventional design has hitherto usually not fulfilled the requirement for universal loading possibilities, simultaneous uncomplicated design and a large measuring range.

Therefore, according to the invention, the load 3 - 3: 7 star of a force-measuring device 122 consists essentially of one or more

Stacking combined mass pieces, the 3.0 of a Absetz.-

scaffold placed on the hanger of the force-normal. or can be taken that the desired power level is achieved in a very short time without Zwischenbe- or intermediate reliefs, the period between the individual power levels (Belastungsz kluszeit) is the same.

For this purpose, in addition to the otherwise usual fixed Absetsgerüst on which the not required for loading mass pieces are stored, a height-adjustable Absetsgerüst inserted, which only serves to take the load required during the loading process for the respective load level from the solid Absetzgerüst and on the Remove hanger. In each case, only the first, usually uppermost masses of one or more Stanel are placed directly on the hanger plates attached to the hanger. Bine depending on the desired power level required number of other hate pieces is attached in a predetermined order to the already stored on the hanger Mass pieces. The coupling elements necessary for this purpose belong, according to the structural design, to the mass of the first mass of a stack or proportionate to each mass,

Laying the first mass pieces on the hanger and attaching more masses can be done almost simultaneously. By constructive measures, such as the same distance between the mass pieces deposited in each case, equal vertical travel distances, etc., an equal load cycle time is achieved, which differs only slightly as a result of the different strains of the suspension rods corresponding to the acting forces.

gestang

Very short combustion cycle times are possible due to very tightly stacked masses and thus short Terfah-rwegen when changing the loading »

Ausführungsbeismel

The embodiment relates to a force ITormalmeßeinrichtung for maximum forces up to 20 klf. Figure 1 shows the two lower mass-stack, Figure 2. the individual construction elements of the Belastungssifstems.

The kreisringförmi.gen, in several stacks stacked mass pieces (1) are surrounded by six columns, of which.

  three the fixed Ahsetzgerüst (2) and three the height-adjustable Absetzgerüst (3) "over the on the uppermost in the outer diameter slightly larger mass of a'Massestückstapels

- Fixed claws (4-), the mass pieces can be placed on the hanger (5), the G-ehängetelier (δ) serve as bearing surfaces.

Also at the top Mas se tee s are on the circumference. Each three vertically hanging metal flat bands (7) attached, which are provided with corresponding slots', in which all other mass pieces of the corresponding stack with their arranged on the circumference pin (8) are stored can. Another three pins (9) on each piece of material serve to store the mass pieces on the push bolts of the fixed Absetsgerüstes (10), and three pins (11) for storage on the sliding bolts of the height-adjustable Absetzgerüstes (12).

The vertical center distances between the sliding bars correspond to the vertical center distances, the slots in d-en Metalifiachbändern.

During the loading process, the bartacks associated with the preselected mass pieces are extended on the height-adjustable setting stand. While then the Absetzgerüst is up in. Its upper end position. Method, lifted, the extended sliding bolt, the mass pieces on the arranged on them pins slightly. The sliding bolts on the fixed Absetzgerüst on which the mass pieces have previously been established, can now be moved back. When lowering the höhenbewegiichen Absetzgerüstes to its lower end position sit in the meantime, the 'first masses of a stack on their claws on them arranged on dia hanger plate, all "/ eiteren mass pieces on their pins in the slots of the metal plates attached to the first plates laugh and load the hanger. "

After the height-adjustable skimming frame has reached its lower end position, the sliding bolts arranged thereon can be moved back, thus concluding a loading process.

A discharge process is carried out analogously.

By means of this load factor, a load or discharge with any desired load for generating the power stage can be provided.

the number of hate-pieces required to occur at the same time is equal to a simultaneous stress sziylrlus, irrespective of the magnitude of the force level.
