The present invention relates to a horizontal / vertical combined projectile assembling apparatus having a flexible assembling position, wherein the assembling apparatus for assembling the projectile is horizontally and vertically assembled without being significantly influenced by the assembling state and the assembling position of the projectile. It is configured to have assembling position as flexible as possible.

In addition, the present invention relates to an assembly apparatus which enables horizontal and vertical assembly of a projectile by reflecting and adjusting various rotation centers in advance in the assembly apparatus rotating unit.

Accordingly, in order to assemble the projectile, it is essential to design and manufacture various assembly devices.

The projectile assembling apparatus carried out as described above is determined according to the method of assembling the projectile. In general, a projectile used in the west applies a vertical assembly method, and in Russia and some countries, mainly a horizontal assembly method is applied.

As such, when the projectile is assembled only completely vertically or only horizontally, the following problems may appear.

First, when assembling a projectile by applying one assembly method, the flexibility of assembly is lowered, and thus, the advantages of other assembly methods cannot be utilized. That is, in the case of vertical assembly, the advantages of horizontal assembly cannot be used, and in the case of horizontal assembly, the advantages of vertical assembly cannot be used.

More specifically, the assembly method is simple in the case of applying the complete vertical assembly as in the former, but as the vertical assembly of the parts increases the height of the projectile, the assembly space having a very high ground clearance to support this and the access facility accordingly are required. This is necessary.

In the case of the complete horizontal assembly like the latter, the projectile accessibility is relatively easy, but the assembling method is complicated, so many assembly apparatuses having various functions are needed in comparison with the vertical assembly.

Second, when assembling a projectile by applying one assembly method to perform optical measurement to check the stage or final assembly state of the projectile, the optical measurement is relatively difficult and the procedure is complicated.

When performing optical measurements to measure projectile assembly at a specific assembly level, the measurement points attached to the projectile envelope are often obscured by the assembly unit or the surrounding facility, resulting in a very long measurement time or days, or the measurement itself is impossible. Occurs.

In addition, vertical assembly requires a fairly large measurement space that can include the size of the vertical assembly, and the like.

Third, when assembling a projectile according to the application of one assembly method, it is relatively difficult to perform a performance test to check the stage or final performance state of the projectile.

In the case of performing a specific assembly or the performance / function test required after the final assembly on a projectile that performs only horizontal assembly or vertical assembly, the test is carried out while maintaining a vertical or horizontal posture close to the actual flight state and a specific flight posture angle. It is desirable to do this, but implementing such a posture is relatively difficult and, in most cases, impossible.

Therefore, the object of the present invention is to measure both the horizontal assembly and vertical assembly without being greatly affected by the projectile assembly level and posture, and the measurement and performance / function test of the projectile while the projectile is fixed to the assembly apparatus at a specific posture angle. It is an object of the present invention to increase the assembling flexibility of the projectile assembly device to enable this.

The present invention can be achieved by additionally applying a rotating assembly in addition to the general fully fixed assembly device to enable the horizontal assembly and vertical assembly of the assembly of the projectile.

The weight of the assembly fixed to the assembly apparatus and its center of gravity are different depending on the assembly level or attitude of the projectile assembled to the assembly apparatus, for example, whether the projectile engine is assembled to the assembly apparatus, whether the structure is mounted or not, and whether the satellite is assembled. will be.

As a result, the weight and center of gravity position for the major expected state of assembly or level can be predicted and calculated.

In addition to this, the total center of gravity of the assembly and the assembly apparatus rotating unit is determined by further considering the weight and the center of gravity of the assembly apparatus rotating unit which is fixed and rotated together with the assembly. At this time, considering the variation width of the center of gravity position according to the main assembly state or posture of the projectile, and reflects in advance to have a variety of rotation center positions reflecting the main assembly state and posture instead of one rotation center in the rotating part.

In order to rotate the projectile that maintains a specific assembly state from horizontal to vertical or vertical to horizontal and a specific attitude angle, the rotating torque is connected to the fixing unit and the rotating unit of the assembly unit by using a manual handle and a reducer installed in the fixing unit of the assembly unit. It must be possible to rotate the projectile at the specific posture angle required by the transmission to the rotating part through the rotating shaft, and to be able to implement the projectile assembly in both the horizontal and vertical state and the specific posture.
