In addition to providing the coiled wing, a tooling for coiling the coiled wing is also provided to coil the coiled wing, thereby making it more convenient for small missiles to be launched through the launch tube. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for rolling arc wings to solve the problems mentioned in the background art.

[0006] The spring fixture includes a torsion spring fixture one and a torsion spring fixture two, which clamp the torsion spring.

[0007] The inner diameter of the wing winding fixture is larger than the outer diameter of the wing shell. After the wing winding fixture is inserted into the outer surface of the wing shell, the wing winding fixture intersects with the wing.

[0008] Preferably, the connecting blocks are installed in parallel in pairs, and three sets of connecting blocks are installed on the outer surface of the arc-shaped wing shell.

[0009] Preferably, the curved wing is a curved arc shape, and the curvature of the curved wing is equal to the curvature of the groove in the wing shell.

[0010] Preferably, the torsion spring fixture one and the torsion spring fixture two are interlocked, and the width of the torsion spring fixture one and the torsion spring fixture two does not exceed the distance between the two connecting blocks.

[0011] Preferably, the torsion spring fixture one and torsion spring fixture two have arc-shaped grooves on their opposite sides to fix the torsion spring, and the inner wall of the arc-shaped grooves fits against the outer surface of the torsion spring.

[0012] Preferably, the arc-shaped slots of the first and second torsion spring fixtures are both through slots, and the connecting shaft passes through the arc-shaped slots and through the axis of the torsion spring to position the torsion spring.

[0013] Preferably, the bottom of the curved wing is provided with a hinge block, which overlaps with the side of the connecting block and is concentrically limited by the connecting shaft.

[0014] Preferably, the outer surface of the coiled wing winding fixture is a rhomboid surface, and the top end of the spring fixture is provided with a slot for pushing the coiled wing.

[0015] The method of using a spiral wing tool consists of the following steps:

[0016] Installation of the tail wing torsion spring:

[0017] 1> The spring fixture consists of two parts: torsion spring fixture one and torsion spring fixture two;

[0018] 2> First, place the torsion spring in the circular groove of torsion spring fixture one, and place torsion spring fixture two on top of torsion spring fixture one, making them close together.

[0019] 3> Torsion spring fixture two works in conjunction with torsion spring fixture one to compress the torsion spring;

[0020] 4> Continue from the previous step and press both ends of the torsion spring into place so that torsion spring fixture one and torsion spring fixture two fit together tightly.

[0021] 5> Place the compressed torsion spring and spring fixture together at the corresponding connecting block hole position on the curved wing shell;

[0022] 6> Place the curved wing in the corresponding position, between the two connecting blocks;

[0023] 7> Insert the connecting shaft into the corresponding hole in the coiled wing housing, passing through the coiled wing and the torsion spring respectively, and then plug it into the other end of the coiled wing housing;

[0024] 8> Remove torsion spring fixture two and torsion spring fixture one to complete the installation of the coiled wing torsion spring;

[0025] Curved wing tooling usage:

[0026] 1> First, make the coiled wing take-up fixture coaxial with the coiled wing shell;

[0027] 2> Connect the coiled wing take-up fixture to the coiled wing shell coaxially, so that the notch surface of the coiled wing take-up fixture contacts the bottom surface of the coiled wing, and the inner hole of the coiled wing take-up fixture is coaxial with the coiled wing shell.

[0028] 3> Push the coiling wing take-up fixture forward so that the front end face of the coiling wing contacts the coiling wing shell, at which point the coiling wing disengages from the slot;

[0029] 4> Rotate the coiling wing take-up fixture so that the outermost edge of the coiling wing take-up fixture's curved surface contacts the coiling wing.

[0030] 5> Continue to rotate the coiling wing take-up fixture. Under the pressure of the curved surface of the coiling wing take-up fixture, the coiling wing is finally gathered up.

[0031] 6> Hold the curled wing with your hand to complete the curling.

[0032] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0033] First, the present invention forms a spring fixture by setting up a torsion spring fixture one and a torsion spring fixture two. When installing the torsion spring, the torsion spring is clamped by the interlocking of the torsion spring fixture one and the torsion spring fixture two, and pressure is applied to both ends of the torsion spring. In this way, when installing the coiled wing, the torsion spring maintains elasticity to the coiled wing, so as to avoid the problem of easy slippage when applying pressure by hand, and achieves the effect of convenient installation of the torsion spring.

[0034] Secondly, this invention sets up a winding fixture for the arc wing and inserts it into the arc wing shell. Then, by rotating the winding fixture, the arc wing is pushed through the groove of the winding fixture, thereby causing the arc wing to rotate and fit against the outer surface of the arc wing shell to achieve winding of the arc wing. Compared with directly winding the arc wing by hand, this invention has the effects of fast winding speed and stable winding. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Method 1

[0045] This embodiment is an implementation of a tooling for a curved wing.

[0046] Please see Figure 1-7 A coiled wing tooling includes a coiled wing housing 1, a spring tooling 6, and a coiled wing winding tooling 7. The coiled wing housing 1 has a groove in the middle, and a connecting block 2 is fixedly connected inside the groove. A connecting shaft 4 is inserted between the grooves of the coiled wing housing 1. The connecting shaft 4 passes through the connecting block 2 and is movably connected to both sides of the coiled wing housing 1. A torsion spring 5 is sleeved on the outer surface of the connecting shaft 4. A coiled wing 3 is movably mounted on the connecting shaft 4. The two ends of the torsion spring 5 overlap with the coiled wing housing 1 and the coiled wing 3, respectively.

[0047] The spring fixture 6 includes a torsion spring fixture 1 601 and a torsion spring fixture 2 602, which clamp the torsion spring 5.

[0048] The inner diameter of the wing winding fixture 7 is larger than the outer diameter of the wing shell 1. After the wing winding fixture 7 is inserted into the outer surface of the wing shell 1, the wing winding fixture 7 intersects with the wing 3.

[0049] Through the above technical solution, by setting torsion spring fixture 1 601 and torsion spring fixture 2 602 to form spring fixture 6, when installing torsion spring 5, torsion spring 5 is clamped by torsion spring fixture 1 601 and torsion spring fixture 2 602 interlocking, and pressure is applied to both ends of torsion spring 5, so that when installing the coiled wing 3, torsion spring 5 maintains elasticity to the coiled wing 3, so as to avoid the problem of easy slippage when applying pressure directly by hand, thus achieving the effect of convenient installation of torsion spring 5;

[0050] By setting up the arc wing rewinding fixture 7 and inserting it into the arc wing housing 1, and then rotating the arc wing rewinding fixture 7, the arc wing 3 is pushed through the groove of the arc wing rewinding fixture 7, thereby causing the arc wing 3 to rotate and fit against the outer surface of the arc wing housing 1, so as to achieve the winding of the arc wing 3. Compared with directly winding the arc wing 3 by hand, it has the effects of fast winding speed and stable winding.

[0051] Specifically, the connecting blocks 2 are installed in pairs in parallel, and three sets of connecting blocks 2 are installed on the outer surface of the arc-shaped wing shell 1.

[0052] The above technical solution sets up a group of two connecting blocks 2 to limit the installation of the spiral wing 3, so that the connecting shaft 4 can pass through the connecting block 2 and the spiral wing 3 can rotate smoothly.

[0053] Specifically, the curved wing 3 is a curved arc shape, and the curvature of the curved wing 3 is equal to the curvature of the groove in the curved wing shell 1.

[0054] Through the above technical solution, the wing 3 is set as a curved arc, so that after the wing 3 is unfolded, it can drive the small missile to rotate under the action of wind, thereby improving the stability of the small missile. Moreover, this curved arc can fit with the outer surface of the wing shell 1 after the wing 3 is folded.

[0055] Specifically, torsion spring fixture 1 601 and torsion spring fixture 2 602 are interlocked, and the width of torsion spring fixture 1 601 and torsion spring fixture 2 602 does not exceed the distance between the two connecting blocks 2.

[0056] Through the above technical solution, the torsion spring fixture 601 and the torsion spring fixture 602 are interlocked, thereby pressurizing the torsion spring 5 and causing the two ends of the torsion spring 5 to contract. The width of the torsion spring fixture 601 and the torsion spring fixture 602 is set so that the spring fixture 6 can enter between the two connecting blocks 2 when installing the torsion spring 5.

[0057] Specifically, the positions where the torsion spring 5 is fixed on opposite sides of torsion spring fixture 1 601 and torsion spring fixture 2 602 are provided with arc-shaped grooves, and the inner wall of the arc-shaped grooves fits against the outer surface of the torsion spring 5.

[0058] Through the above technical solution, arc-shaped slots are opened on the opposite surfaces of torsion spring fixture 1 601 and torsion spring fixture 2 602. The torsion spring 5 is clamped by the arc-shaped slots to prevent the torsion spring 5 from deviating after being subjected to force.

[0059] Specifically, the arc-shaped slots of torsion spring fixture 1 601 and torsion spring fixture 2 602 are both through slots. The connecting shaft 4 passes through the arc-shaped slot and through the axis of the torsion spring 5 to position the torsion spring 5.

[0060] Through the above technical solution, the arc-shaped slots of torsion spring fixture 1 601 and torsion spring fixture 2 602 are set as through slots, so that when installing torsion spring 5, the connecting shaft 4 can pass through the through slot and penetrate the center of torsion spring 5 to fix torsion spring 5.

[0061] Specifically, the bottom of the curved wing 3 is provided with a hinge block, which overlaps with the side of the connecting block 2 and is concentrically limited by the connecting shaft 4.

[0062] Through the above technical solution, a hinge block is set at the bottom of the swivel wing 3, so that the connecting shaft 4 can pass through the hinge block to limit the swivel wing 3, and rotate around the connection between the hinge block and the connecting shaft 4 as the axis when the swivel wing 3 rotates.

[0063] Specifically, the outer surface of the coiling wing take-up fixture 7 is a rhomboid surface, and the top of the spring fixture 6 is provided with a slot for pushing the coiling wing 3.

[0064] Through the above technical solution, the outer surface of the arc wing winding fixture 7 is set into a rhombus shape, so that when the arc wing 3 is wound by the arc wing winding fixture 7, it is convenient to hold the arc wing winding fixture 7 and rotate the arc wing winding fixture 7.

[0071] 3> Torsion spring fixture 2 602 cooperates with torsion spring fixture 1 601 to press the torsion spring 5 tightly;

[0072] 4> Continue from the previous step and press both ends of the torsion spring 5 into place so that the torsion spring fixture 1 601 and the torsion spring fixture 2 602 fit together tightly.

[0073] 5> Place the compressed torsion spring 5 and spring fixture 6 together at the corresponding hole position of the connecting block 2 on the arc-shaped wing housing 1;

[0074] 6> Place the curved wing 3 in the corresponding position, between the two connecting blocks 2;

[0075] 7> Insert the connecting shaft 4 into the corresponding hole of the arc wing housing 1, pass through the arc wing 3 and the torsion spring 5 respectively, and connect it to the other end of the arc wing housing 1;

[0080] 3> Push the coiled wing take-up fixture 7 forward so that the front end face of the coiled wing 3 comes into contact with the coiled wing housing 1, at which point the coiled wing 3 disengages from the slot.
