Description

A tool for closing the tail of a rocket

technical field

The utility model relates to a tool for closing the tail of a rocket, which belongs to the field of assembly and manufacture of rockets.

Background technique

The tail of the rocket is mainly composed of a nozzle to adjust the flow rate and a stabilizer to maintain the flight stability of the projectile. The stabilizer is placed on the periphery of the nozzle. The rocket stabilizer suitable for barrel launch usually adopts the method of circumferentially folding the empennage to be closed on the directional tube in advance, and after the rocket pushes out of the directional tube, the empennage stabilizer is unfolded and fastened to provide lift for it. The assembly of the stabilizer needs to go through the procedures of repairing, trial assembly, pressure spring, closing, and unfolding consistency check. Due to the large spring force and torsional moment of the spring, the traditional process of closing the tail fin requires the cooperation of multiple people, and manual closing is time-consuming and laborious, sometimes causing accidental bumps or injuries to the tail fin, resulting in low labor efficiency.

Utility model content

The purpose of the utility model is to provide a rocket tail closing tool for the traditional process of closing the empennage that requires the cooperation of multiple people, and is time-consuming, laborious, and poor in safety.

The purpose of this utility model is achieved by the following technical solutions:

A tool for closing the tail of a rocket of the utility model includes a clamping table and a stop pin;

There is an annular connection platform in the center of the upper surface of the clamping platform, and the inner wall of the circular connection platform is processed with an internal thread that matches the external thread of the lower end of the spring tail; there are 6 anti-rotation points evenly distributed on the outer circumference of the circular connection platform of the clamping platform Sleeve, the distribution position of the 6 anti-rotation sleeves matches the distribution position of the empennage on the missile tail;

The lower end of the anti-rotation pin is a connecting rod matching the inner diameter of the anti-rotation sleeve, and the upper end of the connecting rod is an anti-rotation disc whose outer diameter is larger than that of the connecting rod;

When the bullet tail is closed, first thread the lower end of the bullet tail to the ring-shaped connection platform of the clamping table, and make each piece of the tail wing opened at the midpoint of the line connecting two adjacent rotation-stopping sleeves; press down a piece of tail wing and make it After it is closed, a detent pin is inserted into the anti-rotation sleeve corresponding to the empennage, and the anti-rotation pin blocks the opening of the empennage through the anti-rotation disk at its upper end; repeat the above-mentioned empennage closing operation, so that each empennage After being blocked by the corresponding anti-rotation pin, put on the clamp to complete the closing of the tail.

The beneficial effects of the utility model:

The tail closing tooling of the utility model has simple structure, convenient operation, and is easy to produce in batches. It not only improves the working efficiency, but also strengthens the protection of products and operators. promotion and application value.

Description of drawings

Fig. 1 is the structural representation of the frock of closing up frock of springtail of the present utility model;

In the figure, 1-fixing card platform; 2-stop pin.

detailed description

Below in conjunction with accompanying drawing and embodiment the content of the present utility model is further described:

Example

A rocket tail closing tooling of the present utility model, as shown in Figure 1, includes a clamping table 1 and a stop pin 2;

There is an annular connecting platform in the center of the upper surface of the clamping platform 1, and the inner wall of the annular connecting platform is processed with an internal thread matching the external thread of the lower end of the spring tail; the outer circumference of the clamping platform 1 is evenly distributed with 6 The anti-rotation sleeve, the distribution position of the six anti-rotation sleeves matches the distribution position of the empennage on the missile tail;

The lower end of the anti-rotation pin 2 is a connecting rod matched with the inner diameter of the anti-rotation sleeve, and the upper end of the connecting rod is a non-rotation disc whose outer diameter is larger than that of the connecting rod;

When the tail of the bullet is closed, the lower end of the tail of the bullet is first threaded on the ring-shaped connecting platform of the fixing table 1, and each piece of the tail that is opened is located at the midpoint of the line between two adjacent rotation-stopping sleeves; a piece of the tail is pressed down and After making it close up, insert a detent pin 2 into the anti-rotation sleeve corresponding to the empennage, and the detent pin 2 blocks the opening of the empennage through the anti-rotation disk at its upper end; repeat the above-mentioned empennage closing operation, so that each After the tail fins are respectively blocked by the corresponding anti-rotation pins, the clips are put on to complete the closure of the tail.
