[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The embodiments of the present application provide a wing installation device and a wing installation method, which can solve the problem in the related art that when installing the wing, it is necessary to position the fixing parts and the wing inside and outside the missile body respectively, which leads to great difficulty and low efficiency in installation.

[0052] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first aspect of the embodiment of the present application provides a wing mounting device, comprising:

[0053] The rotating base 5 includes a fixed base 501 and a rotating base 502 rotatably connected to the fixed base 501. The rotating base 502 is used to install and fix the missile body 1, so that the missile body 1 can be rotated 360 degrees after being fixed on the rotating base 502, so as to switch the missile body 1 to multiple installation positions for installing the missile wings 2.

[0054] The positioning fixture 6 is fixed on the rotating base 502. The positioning fixture 6 is used to clamp and position the fixing part 3. The fixing part 3 is a long metal block with threaded holes. After the positioning fixture 6 clamps the fixing part 3, the fixing part 3 is aligned with the wing mounting hole on the projectile body 1 in the projectile body 1.

[0055] The positioning assembly 7 is fixed on the rotating base 502 and arranged on the outside of the positioning fixture 6 (the outside is defined as: the positioning fixture 6 is relatively far away from the center position of the rotating base 5), and the positioning assembly 7 is used to position the wing 2 so that the wing 2 is aligned with the wing mounting hole on the body 1 outside the body 1.

[0056] The wing mounting device of the embodiment of the present application is provided with a positioning fixture 6 and a positioning assembly 7 on the rotating base 502 of the rotating base 5, wherein the positioning fixture 6 is used to clamp and position the fixing part 3 so that the fixing part 3 is positioned inside the missile body 1 and aligned with the wing mounting hole on the missile body 1, and the positioning assembly 7 is located on the outside of the positioning fixture 6, so as to position the wing 2 outside the missile body 1 and align it with the wing mounting hole on the missile body 1.

[0057] The wing installation device of the present application can solve the problem of the fixing member 3 of the missile body 1 blocking the field of vision, and can simultaneously position the fixing member 3 inside the missile body 1 and the wing 2 outside the missile body 1, and can be rotated and switched in multiple positions. On the one hand, the device can avoid multiple flipping of the workpiece when installing the wing 2, and on the other hand, the completed workpiece can be quickly replaced after installation, which is simple to install, reduces the difficulty of work, and improves the efficiency of wing installation.

[0058] In some optional embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a wing mounting device, in which a rotating base 502 of the device is provided with an annular boss 509 for radially positioning the projectile 1 at one end away from the fixed base 501. The outer diameter of the annular boss 509 is substantially the same as the inner diameter of the projectile 1. When the projectile 1 is mounted on the rotating base 502, the annular boss 509 is located inside the projectile 1 to provide radial positioning for the projectile 1, thereby making the axis of the projectile 1 and the axis of the annular boss 509 collinear.

[0059] There are multiple positioning fixtures 6. The number of positioning fixtures 6 in the embodiment of the present application is the same as the number of wings 2 to be installed on the missile body 1. There are four positioning fixtures 6 in the embodiment of the present application, and the four positioning fixtures 6 are evenly arranged on the top of the annular boss 509 in the circumferential direction. The four positioning fixtures 6 are used to respectively clamp and position the fixing members 3 for installing the four wings 2, and correspond to the four installation points on the missile body 1 for installing the wings 2.

[0060] There are also four positioning components 7. The four positioning components 7 are evenly arranged on the rotating base 502 and correspond one-to-one to the four positioning fixtures 6. The four positioning components 7 surround the outer circumference of the annular boss 509 and are used to position the four wings 2 respectively. When the four wings 2 are respectively positioned by the four positioning components 7, the four wings 2 correspond one-to-one to the four installation points of the wings 2 on the missile body 1.

[0061] In some optional embodiments: See Figure 3 and Figure 6 As shown, the embodiment of the present application provides a wing installation device, wherein the positioning fixture 6 of the device includes a seat body 601, and the seat body 601 is a fan-shaped metal block with a set height. A positioning groove 602 for accommodating and partially exposing the fixing member 3 is provided on one side of the seat body 601 close to the positioning assembly 7, and the positioning groove 602 is provided along the height direction of the seat body 601 and runs through the upper and lower ends of the seat body 601.

[0062] The seat body 601 is also provided with a pressing plate 603 for clamping and fixing the fixing member 3 in the positioning groove 602. The pressing plate 603 clamps or releases the fixing member 3 by moving in a direction close to or away from the fixing member 3. After the fixing member 3 is placed in the positioning groove 602 of the seat body 601, in order to prevent the fixing member 3 from falling out of the positioning groove 602, the present application adds a pressing plate 603 on the seat body 601 to constrain the fixing member 3 in the positioning groove 602.

[0063] Of course, in addition to the present application using the pressing plate 603 to constrain the fixing member 3, those skilled in the art can also use a magnet installed on the seat body 601 to absorb the fixing member 3, and can achieve rapid separation of the fixing member 3 from the seat body 601. A flexible pad can also be added to the positioning groove 602 of the seat body 601. When the fixing member 3 is placed in the positioning groove 602 of the seat body 601, the flexible pad is compressed and deformed to clamp the fixing member 3 to prevent it from falling off.

[0064] In some optional embodiments: See Figure 3 and Figure 6As shown, the embodiment of the present application provides a wing installation device, in which the side of the seat body 601 close to the positioning assembly 7 is a circular arc surface for fitting the inner surface of the body 1, and two positioning grooves 602 are symmetrically arranged in the vertical direction on the circular arc surface of the seat body 601. Since one wing 2 needs to cooperate with two fixing members 3 to be installed on the body 1, the present application provides two positioning grooves 602 on the seat body 601 for positioning and clamping the fixing members 3.

[0065] A slide groove for slidingly connecting the pressing plate 603 is provided at the top of the seat body 601, and the pressing plate 603 can move in a direction close to or away from the fixing member 3 under the guidance of the slide groove. A guide pin 604 is also provided on the pressing plate 603, which is slidably connected to the seat body 601, and the guide pin 604 can drive the pressing plate 603 to move in a direction close to or away from the fixing member 3. There are two pressing plates 603, and the two pressing plates 603 are respectively located at the top of the two positioning grooves 602, and an elastic member 605 is provided on the guide pin 604 to drive the pressing plate 603 to move in a direction close to the positioning groove 602.

[0066] An upper cover plate 606 for closing the slide groove is provided on the top of the seat body 601, and a lower cover plate 607 for closing the positioning groove 602 is provided on the top of the seat body 601. A guide hole for inserting the guide pin 604 is provided on the upper cover plate 606, and the elastic member 605 is a coil spring sleeved on the guide pin 604. One end of the coil spring abuts against the pressure plate 603, and the other end of the coil spring abuts against the upper cover plate 606. A shifting plate 608 for shifting the pressure plate 603 to move away from the positioning groove 602 is provided on the pressure plate 603, and one end of the shifting plate 608 extends out of the seat body 601.

[0067] When it is necessary to position the fixing part 3 in the positioning groove 602 of the seat body 601, first manually push the dial plate 608 upwards, and the dial plate 608 drives the pressure plate 603 and the guide pin 604 to move away from the positioning groove 602, and the spiral spring is compressed to store energy; then the fixing part 3 is placed in the positioning groove 602 of the seat body 601; finally, the dial plate 608 is loosened, and the pressure plate 603 and the guide pin 604 are driven by the elastic push of the spiral spring to move towards the positioning groove 602 to clamp the fixing part 3 to prevent it from falling off in the positioning groove 602.

[0068] In some optional embodiments: See Figure 4 , Figure 6 and Figure 7As shown, the embodiment of the present application provides a wing installation device, the positioning assembly 7 of the device includes a positioning block 701 fixed on a rotating base 502, and a positioning pin 702 and a positioning boss 703 are provided on the top of the positioning block 701 to erect the wing 2 on the positioning block 701. The height of the positioning block 701 is determined according to the distance between the wing 2 and the rotating base 502, and the positioning block 701 is used to support the wing 2 to a set height, so that the mounting hole on the wing 2 is consistent with the height of the wing mounting hole on the missile body 1.

[0069] The positioning pin 702 and the positioning boss 703 on the positioning block 701 are used to clamp the wing 2 in the space between the positioning pin 702 and the positioning boss 703, so as to circumferentially position the wing 2 at the periphery of the missile body 1 and accurately align with the wing mounting hole on the missile body 1. Since the positioning pin 702 and the positioning boss 703 are located outside the missile body 1, the positioning pin 702 and the positioning boss 703 and the missile body 1 can also clamp and fix the wing 2 in the radial direction of the missile body 1.

[0070] In some optional embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a wing installation device, the outer circumferential surface of the annular boss 509 of the device is provided with a plurality of petal-shaped protrusions 511 with uniform intervals, the protrusions 511 can improve the processing technology of the annular boss 509, reduce the friction between the projectile 1 and the annular boss 509, so that the projectile 1 can be quickly loaded and quickly offline after assembly. The rotating base 502 is provided with an annular flange 510 located on the outer periphery of the annular boss 509, and the height of the annular flange 510 is lower than the annular boss 509. An annular groove for partially accommodating the projectile 1 is formed between the annular boss 509 and the annular flange 510, and the bottom surface of the annular groove is used to axially limit the projectile 1.

[0071] A plurality of return spring pins 508 are slidably connected to the annular flange 510, one end of the return spring pin 508 extends toward the annular boss 509, and when the return spring pin 508 is matched with the pin hole on the body 1, the body 1 is fixed on the rotating base 502 to prevent the body 1 from tipping over on the rotating base 502 and causing an accident. The end of the return spring pin 508 is spherical or wedge-shaped, so that the return spring pin 508 can be automatically inserted into the pin hole on the body 1.

[0072] In some optional embodiments: See Figure 1 and Figure 2As shown, an embodiment of the present application provides a wing mounting device, in which a fixed base 501 and a rotating base 502 are rotatably connected via a bearing 504, an inner circle of the bearing 504 is sleeved on the fixed base 501, and the inner ring of the bearing 504 is fixed to the fixed base 501 via an inner ring pressure ring 505, and an outer ring of the bearing 504 is fixed to the rotating base 502 via an outer ring pressure ring 503, thereby reducing the rotational resistance between the fixed base 501 and the rotating base 502.

[0073] A locking block 506 is fixedly provided on the rotating base 502, and a self-locking spring pin 507 is slidably connected to the locking block 506. One end of the self-locking spring pin 507 faces the fixed base 501, and four locking holes evenly distributed in a circle are opened on the fixed base 501. When the self-locking spring pin 507 is inserted into the locking hole, the rotation of the rotating base 502 is restricted, and the rotating base 502 is positioned at the installation position of the bomb wing 2 to prevent the rotating base 502 from rotating itself.
