Description
Technical field
It the utility model is related to a kind of measurement sintered density device, and in particular to a kind of quick measurement manganese-zinc ferrite sintering
Density devices.
Background technology
At present, the mode of company's detection manganese-zinc ferrite core density is still obtained by simple survey calculation, works as chance
Irregular to sample shape, measurement workload will increase, and detection cycle can also extend, and cause to detect data to operation instruction
Reaction speed reduces；And the data of sintered density are a critically important guidances, whether the atmosphere of its direct reaction sintering is accurate
Really, the grinding in production process whether in place, and the small formula doping of production addition whether properly etc. the problems such as, it is and existing
Guide data detection accuracy and periodically can not meet production requirement, if things go on like this, will cause in process of production
There is uncontrollable factor, cause unstable product quality.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of quick measurement manganese-zinc ferrite sintered density dress
Put, including Weighing module, rack module, measurement buoyant module；The Weighing module, including electronic balance, A-frame；It is described
Rack module, including A-frame, support plate；The measurement buoyant module, including water, beaker, sling, sample to be tested；Support
Plate is equipped with water and beaker；The triangle branch is connected with electronic balance；Described sling one end is connected with sample to be tested, the other end with
A-frame upper beam connects.
One kind as the utility model is improved, and sling does not touch any position of beaker with sample to be tested, vertically
Suspend in water.
The utility model has the advantages that：The utility model compared with the prior art one be can rapidly and accurately measure it is close
Degree, detection cycle are short；Second, it can rapidly and accurately measure the weight of various irregular shape manganese-zinc ferrite cores, testing number
According to accurate.Meanwhile it is easy to operate, a people can complete, and save labour.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1. support plates, 2. A-frames, 3. electronic balances, 4. slings, 5. beakers, 6. water, 7. is to be measured
Sample.
Embodiment：
As shown in Figure 1, a kind of quick measurement manganese-zinc ferrite sintered density device, including Weighing module, rack module, survey
Measure buoyant module；The Weighing module, including electronic balance 3, A-frame 2；The rack module, including A-frame 2, branch
Fagging 1；The measurement buoyant module, including water 6, beaker 5, sling 4, sample to be tested 7；Support plate 1 is equipped with water 6 and beaker 5；
The A-frame 2 is connected with electronic balance 3；Described 4 one end of sling is connected with sample to be tested 7, on the other end and A-frame 2
Beam connects.
The shape very irregular of manganese-zinc ferrite core, if going to measure size by conventional means, calculates magnetic core
Volume V, it is difficult, and the discrepancy of calculated value and actual value is very big, the accurate density p for calculating magnetic core is influenced very big；And one
The quick measurement manganese-zinc ferrite sintered density device of kind, is according to Archimedes' principle in physics, weighs up magnetic core first in sky
Weight in gas, is then completely immersed in magnetic core in water, weighs up the weight of magnetic core in water（The weight of sling is subtracted）, twice
The difference of weight is magnetic core suffered buoyancy in water, and the size of the buoyancy suffered by magnetic core is also equal to the liquid arranged by magnetic core
Weight, and the density of water is it is known that the volume i.e. volume of magnetic core for the liquid that can be arranged at last by magnetic core, by having weighed
Weight, just accurately calculate the density of magnetic core.
A kind of quick measurement manganese-zinc ferrite sintered density device, it is as follows that it calculates the formula of parameters：
（1）F=M-m F:Sample to be tested 7 is immersed in the water suffered buoyancy；M:The weight that sample to be tested 7 measures in atmosphere；
m：The weight of sample to be tested 7 in water（The weight of sling is subtracted）；
（2）V=F/ ρ water V:By the volume for arranging liquid of the sample to be tested 7 i.e. volume of sample to be tested 7；ρ water：Water it is close
Spend 1g/cm3；
（3）ρ sample to be tested 7=M/V ρ samples to be tested 7:By the density of sample to be tested 7.
Support plate 1 is to support the beaker 5 equipped with water 6, which cannot touch electronic balance 3 and electronics
A-frame 2 on balance 3, the beaker 5 equipped with water 6 placed in the support plate 1 cannot touch A-frame 2；Triangle branch
Frame 2 is to measure the key scaffold that magnetic core enters buoyancy F, and 4 one end of sling of known weight is connected with sample to be tested 7, is restricted
4 other ends are detained to be connected with 2 upper beam of A-frame again, sling 4 and sample to be tested 7 must not touch 5 any position of beaker herein,
Can only vertical suspension in water 6.After sample to be tested 7 is immersed in the water, weight just can be weighed.
