Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of gravity center measurement device make further it is detailed
It describes in detail bright.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached
Figure is all made of very simplified form and using non-accurate ratio, only to convenient, lucidly aid illustration is originally practical new
The purpose of type embodiment.
Embodiment one
The utility model provides a kind of gravity center measurement device, and structure is as shown in Figure 1.Specifically please continue to refer to Fig. 1,
The gravity center measurement device includes support rotary shaft 1, is equipped with balancing pole 2 in the support rotary shaft 1；With the balancing pole 2
It is arranged in parallel with graduated scale 3.One end of the balancing pole 2 is equipped with locating support 4, is equipped with dynamometer 5 at the top of the other end, into
One step, the dynamometer 5 is mounted on the top of the balancing pole 2 by dynamometer bracket 6, and the dynamometer 5 preferably counts
Aobvious dynamometer, reflects the stress condition of the balancing pole 2 in real time.
Specifically, pallet 7 is fixedly installed on the locating support 4, for placing testee；The graduated scale 3 is put
It sets in the pallet 7, can intuitively reflect the position of centre of gravity of testee.Preferably, spiral shell is provided on the locating support 4
Pit is screwed into positioning bolt 8 with the testee in the fixation pallet 7 in Xiang Suoshu threaded hole；Further, described fixed
The two sides of position bracket 4 are respectively equipped with four threaded holes, amount to 8 positioning bolts by adjusting, irregularly shaped object may be implemented
Step up.
Those skilled in the art understand that the gravity center measurement device can also include pedestal 9, the support rotation
Axis 1 is located on the pedestal 9, and the pedestal 9 can carry the support rotary shaft 1；Further, the dynamometer bracket 6
It is also mounted on the pedestal 9.
Gravity center measurement device principle to be measured provided by the utility model are as follows: under original state, due to the balancing pole 2
One end is equipped with fixed bracket 4, therefore this one end is heavier, and under 5 position-limiting action of dynamometer, the balancing pole 2 is located always
In horizontality, 5 numerical value of dynamometer is F at this time1；Testee own coordinate is determined according to the features of shape of testee
System pays attention to the X-direction of testee local Coordinate System first and graduated scale side as shown in Fig. 2, putting it into the pallet 7
To parallel, referring to Fig. 3, the relative position of tested direction X is X0, the numerical value of the dynamometer 5 is F at this time2, then testee
The X-direction position of centre of gravity L of the relatively described support rotary shaft 1xAre as follows:
In above formula, L0It is the arm of force in dynamometer direction, M1It is the quality of testee, g is acceleration of gravity.So, Lx
With X0Difference x=Lx-X0The as position of centre of gravity of testee, similarly, by adjusting testee in the pallet 7
Put so that the Y-direction and Z-direction of testee local Coordinate System are parallel with graduated scale direction respectively, can obtain respectively Y and
The position of centre of gravity of Z-direction.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Fixed, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content belong to right and want
Seek the protection scope of book.
