Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 6: a device capable of realizing high-efficiency detection of the gravity center of a bomb comprises a first support frame 1, a second support frame 2, a tip 3 and a platform scale 4,

The working process of the device capable of efficiently detecting the gravity center of the bomb provided by the embodiment of the utility model is as follows: firstly, a centre 3 is placed on a platform balance 4 to form a centre assembly, two first support frames 1, a second support frame 2 and the centre assembly are arranged in a row, the two first support frames 1, the second support frame 2 and the centre assembly are adjusted to be collinear, then a bomb needing gravity center detection is placed on the two first support frames 1 by utilizing a lifting appliance, at the moment, a rubber gasket 11 in a first arc-shaped frame 10 at the top of each first support frame 1 is in contact with the outer surface of the bomb, first hand wheels 8 on the two first support frames 1 are respectively rotated to drive a first nut block 7 to rotate, further, a first lead screw 9 in threaded connection with the first nut block 7 is driven to drive the first arc-shaped frame 10 at the top end to move longitudinally, the bomb is adjusted to be in a completely horizontal state by the mode, then a top rod 23 is rotated to be moved upwards relative to a top seat 22 until the top of the top rod 23 is in contact with the bottom of the bomb (the centre assembly is arranged at one end close to the tail part of the bomb), at the moment, the bomb depends on the two first supporting frames 1 for supporting;

rotating a second hand wheel 15 to drive a second nut block 14 to rotate, further enabling a second lead screw 16 to move upwards, pushing a connecting seat 18 to move upwards by a conical tip 17 at the top end of the second lead screw 16 until a rubber gasket 11 in a second arc-shaped frame 21 is contacted with the outer surface of a bomb, then reversely rotating first hand wheels 8 in two first supporting frames 1, enabling the first arc-shaped frame 10 to move downwards and to be separated from and contacted with the bomb, and enabling the bomb to be supported only by the second supporting frame 2 and the tip; because the second lead screw 16 in the second support frame 2 is movably connected with the connecting seat 18 at the top end thereof, that is, the second arc-shaped frame 21 can slightly swing along the radial direction of the bomb, the operator can finely adjust the second arc-shaped frame, when the longitudinal perpendicular line of the connecting seat 18 is coaxial with the second lead screw 16, the axial line of the second lead screw 16 is perpendicular to and coplanar with the axial line of the bomb, and at the moment, the second support frame 2 effectively supports the bomb in the gravity center detection process;

meanwhile, the scale 4 also displays the pressure born by the tip 3 at the moment, which is marked as G1; the total weight of the bomb was G (known); the distance between the second support 2 and the tip 3 is a (measured); assuming that the distance from the second support frame 2 to the center of gravity of the bomb is X (as shown in fig. 6), the following formula can be obtained according to the moment balance formula:
