Abstract
The utility model relates to a weight deflection preventing device, comprising a lifter (8) and a damping absorbing device; the weight deflection preventing device is arranged at a free end of a lifting rod (2) for loading a weight; and the lifter (8) is used for driving the damping absorbing device to be close to the free end and abut against the free end. When the weight is loaded, a cushion pad (6) abuts against the free end of the lifting rod (2), therefore, a stable supporting point to the lifting rod (2) is formed; and under the function of the supporting point, the free end of the lifting rod (2) does not generate violent deflection. Therefore, even though a matching gap exists between a through hole of the weight and the lifting rod, the lifting rod (2) can not generate deflection.
Description
Technical field
The utility model relates to anti-deflection device, particularly relates to the device that prevents the counterweight beat.
Background technology
In the process that pressure or pulling force sensor are demarcated, normally undertaken in the prior art by the mode of hierarchical loading counterweight, every grade of counterweight has three or four support portions, during loading, each support portion all is subjected to the driving of a special lifter and the motor that drives described lifter and loads up and down, when loading class 1st weight, operate the lifter and the motor of each support portion correspondence simultaneously, three or four support portions are descended simultaneously, thereby counterweight is loaded on the suspension rod, by described suspension rod counterweight is loaded into pressure to be tested or pulling force sensor again.
Counterweight of the prior art has through hole in the middle of being generally oblate column, and described suspension rod passes the through hole at counterweight center, and by the support ring on the suspension rod weight of himself is loaded on the suspension rod, and the lower end of suspension rod is a free end.Described through hole all has the diameter bigger than described suspension rod usually, so beat can take place on suspension rod counterweight, thereby influences stated accuracy.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, dependable performance, can prevent in the process that counterweight loads, because the Weight anti-deflection device that through hole on the counterweight and the tolerance clearance between the suspension rod cause the suspension rod beat.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of Weight anti-deflection device, comprise lifter and damping absorption plant, and described Weight anti-deflection device is arranged at the free end of the suspension rod that is used to load counterweight; Described lifter is used to drive described damping absorption plant and connects near described free end and with described free end.
Preferably, described damping capacity absorption plant is a flexure spring damping capacity absorption plant.
Preferably, described damping capacity absorption plant is arranged on the pallet of output terminal of described lifter.
Preferably, described damping capacity absorption plant comprises lower bolster (9), upper padding plate (7), cushion pad (6) and is arranged at a plurality of springs (10) between described upper and lower backing plate (9,7); Described cushion pad (6) is arranged on the described upper padding plate (7).
The utility model also provides a kind of force sensor caliberating device, it is characterized in that: comprise described Weight anti-deflection device.
When loading counterweight, cushion pad and described suspension rod free end are connected, thereby form a stable fulcrum described suspension rod, under the effect of described fulcrum, make the free end of described suspension rod that violent beat no longer take place.Therefore, even have tolerance clearance between the through hole of counterweight and the described suspension rod, can therefore not make suspension rod generation beat yet.
Description of drawings
Fig. 1 is the structural representation of force sensor caliberating device.
Fig. 2 is the synoptic diagram of Weight anti-deflection device.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
Fig. 1 shows the structural representation of counterweight charger.Charger as shown in Figure 1 comprises reverse frame mechanism 1, suspension rod 2 and counterweight driving mechanism 3.
Described reverse frame mechanism 1 is used for to pressure to be calibrated or pulling force sensor imposed load, and its lower end connects described suspension rod 2; On described suspension rod 2, be equipped with a plurality of counterweight driving mechanisms 3.
Fig. 2 shows the Weight anti-deflection device in the utility model.As shown in Figure 2, described Weight anti-deflection device is arranged at the free-ended below of described suspension rod 2, comprises lifter 8 and flexible damping capacity absorption plant; Described flexible damping capacity absorption plant is arranged on the pallet of output terminal of described lifter, and it comprises lower bolster 9, upper padding plate 7 and cushion pad 6, is provided with a plurality of springs 10 between described upper and lower backing plate; Described cushion pad 6 is arranged on the described upper padding plate 7, is used for connecting with the free-ended lower surface of described suspension rod 2.
Preferably, described cushion pad 6 is a cushion.
When loading counterweight, operate described Weight anti-deflection device earlier, make of the direction motion of its lifter 8 to described suspension rod 2, up to cushion pad 6 and described suspension rod 2 free-ended lower surfaces are connected, thereby form a stable fulcrum to described suspension rod 2, under the effect of described fulcrum, make the free end of described suspension rod 2 that violent beat no longer take place.Therefore, even have tolerance clearance between the through hole of counterweight and the described suspension rod, can therefore not make suspension rod 2 that beat takes place yet.
Claims (5)
1. a Weight anti-deflection device is characterized in that, comprises lifter (8) and damping capacity absorption plant, and described Weight anti-deflection device is arranged at the free end of the suspension rod (2) that is used to load counterweight; Described lifter (8) is used to drive described damping capacity absorption plant and connects near described free end and with described free end.
