When assembling the gravity center measurement device 100 of present embodiment, first, the first measuring piece 24 and the second measuring piece 26 are fixed on pedestal 22.Then, keeper 44 is installed on support member 42, and bearing part 46 is connected with support member 42, then the bearing assembly 40 assembled is arranged on measurement components 20, make wherein two support members 42 correspond respectively to the first measuring piece 24 and the second measuring piece 26.Finally, fixture 62 is installed on bearing part 46, then movable part 64 is arranged on fixture 62.
Please refer to Fig. 5, when using the gravity center measurement device 100 of present embodiment, first, the gravity center measurement device 100 assembled is positioned in a horizontal table (not shown), then movable part 64 is regulated, make the first measuring piece 24 identical with the registration of the second measuring piece 26 or substantially identical, then object 200 to be measured is positioned on bearing part 46 to measure its center of gravity.
Secondly, observe the registration of the first measuring piece 24 and the second measuring piece 26, if the registration of the two is beated or in the non-steady state constantly changed, then wait for a period of time, until the registration of the first measuring piece 24 and the second measuring piece 26 can stablize display.If the first measuring piece 24 is shown as M1, the second measuring piece 26 is shown as M2, if the quality of this object 200 to be measured is m.
Then, with the strong point at support member 42 place away from first side 461 for starting point, the straight line that the strong point reading two other support member 42 place defines is L1 to the distance of described starting point, and to read object 200 to be measured near the distance of the edge of described starting point and this starting point part be L2, set the center of gravity of object 200 to be measured and the distance of this starting point part as L3 again, if the center of gravity of this object 200 to be measured is L to its distance near the edge of described starting point, can be obtained by mechanical balance principle:
(M1+M2)*L1=m*L3;
Know by inference:
L3=(M1+M2)*L1/m；
Thus the distance at its edge of distance of centre of gravity of object 200 to be measured:
L=L3-L2=(M1+M2)*L1/m-L2.
Gravity center measurement device 100 of the present utility model, measured by the first measuring piece 24 and the second measuring piece 26 and show bearing part 46 and on object to be measured quality after, set up mechanical model, by simply calculating the relative position that just can draw object 200 center of gravity to be measured, the simple and simple operation of its structure.Meanwhile, the support portion 421 of support member 42 is in cone shape, and the contact between itself and measurement components 20 is roughly point cantact, can ensure that gravity center measurement device 100 has higher measuring accuracy.Because the structure of gravity center measurement device 100 is simple, it is after repeated disassembled and assembled, when again measuring the centre of gravity place of object 200, can read parameter easily, and calculates to obtain the center of gravity relative position of object 200 by setting up mechanical model, and repeatability precision is high.
Be appreciated that, the quantity of support member 42 can be two, correspondingly, second measuring piece 26 is omitted, and the shape being designed to bearing part 46 to be applicable to two support members 42 is (as rectangular plate-like, circular plate-like shape etc., even, when bearing part 46 can firm support on these two support members 42 time, its shape can not change), and one of them support member 42 is changed to 2 points/Multi-contact with the contact point of measurement components 20 or face contacts, to make these two support members 42 can firmly support bearing part 46 and object 200 to be measured.In like manner, when using this gravity center measurement device, adopt above-mentioned methods of measurement and calculation also can calculate the relative position of object 200 center of gravity to be measured easily:
First, object 200 to be measured is positioned on bearing part 46, and the registration reading the first measuring piece 24 is M11, if the quality of this object 200 to be measured is m1.Then, read two support member 42 places the strong point between distance L11; With the strong point at support member 42 place away from the first measuring piece 24 for starting point, reading object 200 to be measured near the distance of the edge of described starting point and this starting point part is L21; Set the center of gravity of object 200 to be measured and the distance of this starting point part as L31 again, if the center of gravity of this object 200 to be measured to its distance near the edge of described starting point is l, by mechanical balance away from obtaining:
M11*L11=m1*L31;
Know by inference:
L31=M11*L11/m1；
Thus the distance at its edge of distance of centre of gravity of object 200 to be measured:
l=L31-L21=M11*L11/m1-L21.
In like manner, the quantity of support member 42 can be four or more, and when using gravity center measurement device 100, the quantity according to the support member 42 of reality employing in like manner converts mechanical model, namely can calculate the relative position of object 200 center of gravity to be measured.
