Description
Technical field
The present invention relates to the dead weight force measuring machine, particularly the reverse frame hanging device of dead weight force measuring machine.
Background technology
Sensor is to be used for directly or indirectly and measurand is got in touch, and measured parameter is changed into the signal that can directly measure, and it provides the necessary raw information of handling and make a strategic decision for system, is the key link in the modern detection system.Along with the appearance of various sensor, require production metrological service that it is tested comprehensively and accurately, examines and determine, and provide consistent reliable technique index.And in the test of sensor, evaluation, calibration process, force standard machines is that force measuring machine is its key equipment.
Dead weight formula force measuring machine is mainly used in the dynamometry and the LOAD CELLS of calibrating or calibration criterion dynamometer and corresponding accuracy, carry out the force measurement work of transmission of quantity value and pin-point accuracy, dynamic effect according to power, adopting the gravity that had of dead weight counterweight in gravity field directly to reappear the power value, is the method for the highest a kind of power of the reproduction value of the modern science and technology accuracy that can reach.Dead weight formula force measuring machine is the highest force measuring machine of accuracy, and national benchmark adopts the type mostly.
When dead weight formula force measuring machine of the prior art loaded counterweight, its reverse frame was fixedlyed connected with suspension rod, so the weight of suspension rod can act directly on the sensor to be measured on the reverse frame.When to need original upload be zero experiment, reverse frame of the prior art is hung frame can not realize that just mother's zero load loads.
In addition, counterweight of the prior art all is fixing loaded value, owing to described loading counterweight the time, need simultaneously the weight of reverse frame and suspension rod all can be affacted on the sensor to be measured, therefore can not realize the loading less than minimum counterweight loaded value.
In addition, when all counterweights all had been loaded, loaded value if desired can not realize loading during greater than the weight of all counterweights with force measuring machine of the prior art in the prior art.
Summary of the invention
The purpose of this invention is to provide the reverse frame hanging device that a kind ofly can initial zero load, load, load greater than all counterweight weight less than minimum counterweight weight for force measuring machine provides.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of reverse frame hanging device, comprise reverse frame mechanism and suspension rod, and described reverse frame mechanism has last connecting portion and following connecting portion, and the connecting portion that descends is connected with described suspension rod, it is characterized in that:
Described device also comprises jacking gear, and it is connected with the described connecting portion of going up;
Having of described suspension rod is arranged at described first snap ring and second snap ring of the upper and lower both sides of connecting portion down respectively;
Described connecting portion down is connected with described suspension rod between described first and second snap rings slidably.
By the described mode that is slidingly connected, the device among the present invention can provide initial zero to load, load, load greater than all counterweight weight less than minimum counterweight weight for force measuring machine.
Description of drawings
Fig. 1 is the structural representation of dead weight machine experimental provision.
Fig. 2 is the structural representation of loading portion.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 1 shows the structural representation of force sensor caliberating device.Device as shown in Figure 1 comprises loading portion 1, suspension rod 2 and Weight synchronous loading and unloading device 3.
Described loading portion 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 is the structural representation of loading portion.As shown in Figure 2, described loading portion 1 comprises motor 10, moving beam 12, oppositely frame mechanism 13, back timber 17, screw rod 19 and base plate 18.
Described moving beam 12 can move along the vertical of threaded column 111 of described loading portion 1, and can be fixed on arbitrary position of described screw thread, and it has a pallet 110.
Described reverse frame mechanism 13 has last connecting portion 14 and following connecting portion 15, and it is connected with described screw rod 19 by the described connecting portion 14 of going up, and pass through the connecting portion 15 that descends be connected with described suspension rod 2.Pressure transducer to be measured is placed in described pallet 110 and described going up between the connecting portion 4, after counterweight is added on the described suspension rod 2, described suspension rod 2 moves downward, thereby drive described reverse frame mechanism 13 and on last connecting portion 14 move downward, because described moving beam 12 is fixed on the column 111, therefore pressure transducer to be measured is applied certain load, so that it is demarcated.Described screw rod 19 can move up and down with respect to back timber 17 under the driving of described motor 10.
Shown in Fig. 2-3, the upper end of described suspension rod 2 is provided with first snap ring 21 and second snap ring 22, described suspension rod 2 passes described connecting portion 15 down, and described first and second snap rings 21,22 are arranged at the described upper and lower both sides of connecting portion 15 down respectively, and can contact with the upper surface of described back timber 17 and base plate 18 respectively.Preferably, the bottom of described first and second snap rings respectively has a boss that is used to locate, and simultaneously, on the described back timber 17 corresponding with described first and second snap rings and the upper surface of base plate 18, has the groove that matches with described boss.Preferably, described boss is the frustum of a cone.
When described second snap ring 22 is placed in the upper surface of described base plate 18, because the effect of described second snap ring 22, when described first snap ring 21 separates with the described upper surface of going up connecting portion 15, the weight of described suspension rod 2 can not be applied on described reverse frame mechanism 13, therefore can realize the zero load of sensor to be measured is loaded.At this moment, move downward, then can realize only applying load by 10 pairs of sensors to be measured of motor if operate the reverse frame mechanism 13 of described screw rod 19 drives of described motor 10 drivings.
When reverse frame mechanism 13 upwards being mentioned by described motor 10, and when described second snap ring 22 is contacted with the lower surface of following connecting portion 15, described first snap ring 21 breaks away from the upper surface of following connecting portion 15, at this moment, when not loading under the situation of counterweight to described suspension rod 2, only there is the weight of suspension rod 2 to act on the sensor to be measured, thereby can realizes than all little loaded value of any counterweight weight.At this moment, drive described screw rod 19 and drive reverse frame mechanism 13 and move downward, then can realize sensor to be measured being applied load by the weight of motor 10 and described suspension rod 2 oneself if operate described motor 10.
