Description

Technical Field

[0001] The present invention relates to a circumferential positioning mechanism for a rocket rear end cabin, belonging to the technical field of rocket performance detection Background Art

[0002] During the later storage and maintenance of a series of rockets, regular warehouse inspections are required. The inspection items mainly include: rocket appearance inspection, swing difference inspection, electrical performance inspection, and spring inspection of some rockets. For rockets with abnormal electrical performance during the inspection, the control cabin must be replaced to ensure the normal use of the rocket. The loading and unloading of rockets are all completed on the support trolley. During assembly after inspection, it is necessary to ensure the phase angle relationship between the control cabin and the rear end cabin, which requires the circumferential positioning of the rocket control cabin and the rear end cabin of the rocket. The circumferential positioning structure for the rear end cabin of the rocket on the existing support trolley is a socket structure corresponding to the directional button. When the rear end cabin of the rocket is placed on the support trolley, it is necessary to ensure that the directional button of the rear end cabin of the rocket is aligned with the socket structure on the support trolley, which increases the difficulty of lifting and is prone to damage to the directional button due to inaccurate placement. Summary of the invention

[0003] The purpose of the present invention is to provide a circumferential positioning mechanism for a rocket rear end cabin to ensure the phase angle relationship between the rocket control cabin and the rocket rear end cabin.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A circumferential positioning mechanism for a rear end cabin of a rocket of the present invention comprises a connecting bottom plate, a horizontal guide rail arranged on the left side of the upper surface of the connecting bottom plate, a vertical fixing plate fixed on the right side of the upper surface of the connecting bottom plate, a guide rod vertically fixed on the left side of the vertical fixing plate, a directional button locking block slidably connected to the horizontal guide rail, a pull ring rotatably connected to the right side of the directional button locking block, and a spring for driving the directional button locking block to move to the left side;

[0006] A guide rod connecting hole is horizontally opened at the lower end of the directional button locking block, and a spring mounting groove is opened at the right section of the guide rod connecting hole; a horizontal plug-in plate is arranged at the upper end of the directional button locking block, and a positioning long hole whose width matches the diameter of the rocket directional button is opened at the left end of the horizontal plug-in plate.

[0007] A pull ring clamping portion is provided on the right side of the upper end of the vertical fixing plate;

[0008] The left end of the guide rod is inserted into the guide rod connecting hole of the directional button locking block, and the spring is sleeved at the guide rod between the directional button locking block and the vertical fixing plate, so that the directional button locking block moves to the left along the horizontal guide rail when the spring is free; by pulling the pull ring, the directional button locking block moves to the right along the horizontal guide rail and compresses the spring, and the pull ring flips to the right side until it is locked with the pull ring locking part of the vertical fixing plate, thereby limiting the right side movement of the directional button locking block;

[0009] The circumferential positioning mechanism is fixed on the supporting trolley for supporting the rear section cabin of the rocket through the connecting base plate, so that the positioning long hole of the horizontal plug-in plate at the upper end of the directional button locking block is aligned with the circumferential position of the directional button of the rear section cabin of the rocket.

[0010] The left end of the positioning long hole of the horizontal plug plate is processed into a tapered guide section, which is convenient for automatic alignment when the directional button is inserted.

[0011] Working process

[0012] Before placing the rocket's rear section cabin, first pull the pull ring to move the directional button locking block to the right along the horizontal guide rail and compress the spring, and the pull ring flips to the right to engage with the pull ring engaging portion of the vertical fixing plate, limiting the right side movement of the directional button locking block, so that the long positioning hole of the horizontal plug-in plate at the upper end of the directional button locking block makes way for the directional button position of the rocket's rear section cabin; then place the rocket's rear section cabin on the supporting trolley, and adjust the circumferential position of the directional button of the rocket's rear section cabin to align with the circumferential positioning mechanism; then remove the pull ring from the pull ring engaging portion of the vertical fixing plate, and the directional button locking block moves to the left along the horizontal guide rail under the elastic force of the spring, so that the long positioning hole of the horizontal plug-in plate at the upper end of the directional button locking block engages with the directional button of the rocket's rear section cabin, thereby realizing the circumferential positioning of the rocket's rear section cabin.

[0013] Beneficial Effects

[0014] The circumferential positioning mechanism of the present invention has a simple structure and is easy to use. It can quickly realize the circumferential positioning of the rear section of the rocket, facilitate the disassembly and assembly of the rocket, and meet the use requirements for rocket detection.
