DETAILED DESCRIPTION

[0019] The present application will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present application. These all belong to the protection scope of the present application.

[0020] As Figures 1-8As shown, the semi-automatic fairing vertical closing device provided by the application comprises a support frame upper section 1, a rolling bending and twisting corrector 2, a guide device 3, a support frame middle section 4, a star cover butt joint supporting platform 5, a support frame lower section 6 and a six-degree-of-freedom parallel adjusting mechanism 7. The star cover butt joint supporting platform 5 is used for supporting a star cover assembly and determining the position of a fairing 8. The support frame upper section 1, the support frame middle section 4 and the support frame lower section 6 are sequentially connected from top to bottom to form a set of half support frames. Two half fairings 8 are respectively installed in the two sets of support frames, and the fairing 8 is positioned and connected with the support frame through the guide device 3. The two sets of support frames are respectively arranged on the two sides of the star cover butt joint supporting platform 5, and each set of support frame is provided with three six-degree-of-freedom parallel adjusting mechanisms 7 at the bottom. The posture of the fairing 8 is adjusted by driving the support frame through the six-degree-of-freedom parallel adjusting mechanism 7. A plurality of rolling bending and twisting correctors 2 are arranged between the support frame and the fairing 8, and the two half fairings 8 are adjusted and closed through the rolling bending and twisting corrector 2. The fairing vertical closing device can realize the functions of guiding, connecting, supporting, moving, posture adjusting and deformation correction of the fairing 8.

[0021] The support frame upper section 1 is of a von Karman structure, the support frame middle section 4 is of an arc barrel structure, and the support frame lower section 6 is of an inverted conical structure. The support frame upper section 1, the support frame middle section 4 and the support frame lower section 6 are tightly connected to form a melon petal opening structure matching the shape of the fairing 8, which can adapt to fairings 8 of different heights and diameters, reliably connect with the fairing 8, support the fairing 8, and realize the functions of lifting and overturning the fairing 8.

[0022] A plurality of rolling bending and twisting correctors 2 are installed at the opening of each set of support frame, and the rolling bending and twisting correctors 2 are distributed along the adjusting holes of the fairing 8. After the left and right half fairings are closed, the deformation of the fairing 8 caused by bending and twisting makes the bolt holes of the left and right half fairings unable to be closed. The rolling bending and twisting corrector 2 is used to top and pull the adjusting holes to realize the closing of the bolt holes of the left and right half fairings. The rolling bending and twisting corrector 2 can adjust the deformation of the fairing 8 caused by processing, self weight and other reasons, and improve the butt joint efficiency of the fairing 8. The rolling bending and twisting corrector 2 comprises a rolling bending and twisting ball head 21, a fixed seat 22, a force transmission rod 23 and a handle 24. The fixed seat 22 is installed on the support frame through a waist-shaped hole and a bolt assembly, and can be adjusted along the length direction on the support frame through the waist-shaped hole to adapt to the bending and twisting deformation of the fairing 8. The middle part of the force transmission rod 23 is installed on the fixed seat 22, the rolling bending and twisting ball head 21 and the handle 24 are respectively arranged at the two ends of the force transmission rod 23, and the rolling bending and twisting ball head 21 is connected with the fairing 8. When the rolling bending and twisting corrector 2 is fixed on the support frame, the handle 24 can be operated to drive the rolling bending and twisting ball head 21 to perform multi-degree-of-freedom bending and twisting adjustment, thereby improving the assembly efficiency.

[0023] The guide device 3 is used for precise positioning of the fairing 8 when it is placed on the support frame. The guide device 3 includes a limiting mechanism 31 and a guide rod 32. The limiting mechanism 31 is installed on the fairing 8, and the guide rod 32 is installed on the support frame. It plays a positioning role when the fairing 8 is fixedly connected to the support frame in a horizontal state, thereby speeding up the assembly process. The guide rod 32 is inserted into the limiting hole 311 on the limiting mechanism 31. The guide rod 32 includes a straight rod 321 and a mounting base 322. Guide devices 3 are symmetrically installed on both sides of the opening of any set of support frames. The two mounting blocks 314 at the bottom of the limiting mechanism 31 are respectively fastened to the upper section 1 and the middle section 4 of the support frame. The limiting mechanism 31 also includes a reinforcing rib 312 and a support beam 313. The two mounting blocks 314 are respectively set at both ends of the support beam 313, and the limiting hole 311 is fixed to the support beam 313 by the two reinforcing ribs 312.

[0024] The six-degree-of-freedom parallel adjustment mechanism 7 can automatically realize the movement, turning, translation, pitch, and torsion of the overall structure and the product. Three six-degree-of-freedom parallel adjustment mechanisms 7 are evenly arranged at the bottom of the support frame. The six-degree-of-freedom parallel adjustment mechanism 7 includes, from bottom to top, the following: drive wheel 71, lifting mechanism 72, and two-position linear slide 73. More specifically, it consists of a servo motor, lifting screw, guide cylinder, vertically intersecting and spliced ​​linear slide, and controller. The two-position linear slide 73 is fastened to the lower section 6 of the support frame. The support frame can turn and move by being driven by the drive wheel 71, can move up and down by being driven by the lifting mechanism 72, and can translate on the horizontal plane by being driven by the two-position linear slide 73. The vertical assembly of the fairing is raised and lowered by three parallel six-degree-of-freedom adjustment mechanisms 7. The lateral deflection of the vertical assembly of the fairing is achieved by adjusting the two parallel six-degree-of-freedom adjustment mechanisms 7 on the left and right sides of the lifting frame. The pitch of the vertical assembly of the fairing is achieved by adjusting the middle parallel six-degree-of-freedom adjustment mechanism 7. The longitudinal rotation of the fairing 8 is achieved by adjusting the two-position linear slide 73.

[0025] The star-shaped dome support platform 5 includes a support moving mechanism 51 for support and movement. The support moving mechanism 51 is symmetrically provided with limit insertion holes 52 on both sides. The six-degree-of-freedom parallel adjustment mechanism 7 located in the middle of the support frame is provided with positioning teeth. The positioning teeth are inserted and cooperate with the limit insertion holes 52 to position the support frame, saving movement and positioning time and improving work efficiency.

[0026] A method for using a semi-automatic fairing vertical closing device includes the following steps: Step S1: Lift the left and right halves of the fairing 8 which are in a horizontal position, and accurately place them onto the left and right horizontal support frames respectively through the guide device 3, and connect the fairing 8 to the support frame through the 8 screw holes on the back of the fairing 8. Step S2: Flip the fairing 8 and the support frame to a vertical position; Step S3: Control the six-degree-of-freedom parallel adjustment mechanism 7 on the two sets of support frames to move to both sides of the star-faced docking support platform 5, and adjust the fairing vertical closing device so that the positioning pins on the six-degree-of-freedom parallel adjustment mechanism 7 are vertically inserted into the limiting pinholes 52 on the star-faced docking support platform 5. Step S4: Adjust the six-degree-of-freedom parallel adjustment mechanism 7 on a set of support frames so that half of the fairing 8 is adjusted to the preset position, and use it as the adjustment reference to adjust the other half of the fairing 8. Step S5: Adjust the turning torque corrector 2 so that the bolt holes of the left and right halves of the fairing 8 are aligned. Step S6: After the left and right halves of the fairing 8 are assembled, control the six-degree-of-freedom parallel adjustment mechanism 7 on the two sets of support frames to descend simultaneously to the fairing docking support platform 5, so that the fairing 8 falls onto the fairing docking support platform 5. Finally, disconnect the semi-automatic fairing vertical fairing assembly device from the fairing 8 and exit the assembly.

[0027] In step S4, a spatial rectangular coordinate system is established with the vertically upward X-axis coinciding with the center line of the fairing 8, pointing from the tail of the fairing 8 towards the head, and the horizontal plane as the YZ plane, with the Z-axis perpendicular to the connecting surface of the two halves of the fairing 8. Steering and walking actions are performed via the drive wheels 71. The height of the fairing 8 is adjusted synchronously by controlling the lifting mechanisms 72 of the three six-degree-of-freedom parallel adjustment mechanisms 7 on a set of support frames. The fairing 8's rotation around the Z-axis is adjusted by controlling the lifting mechanisms 72 on both sides of the set of support frames to rise and fall alternately. The fairing 8's rotation around the Y-axis is adjusted by controlling the lifting mechanism 72 in the middle of the set of support frames to rise and fall, or by using the lifting mechanism 72 to rise and fall alternately. The translational movement of the fairing 8 in the YZ plane and its rotation around the X-axis are adjusted by the two-position linear slide 73 of the six-degree-of-freedom parallel adjustment mechanism 7.

[0028] This application utilizes a support frame consisting of three sections to support fairings 8 of different heights and diameters; a guide device 3 assists in horizontally hoisting the fairing 8 onto the support frame and fixing it thereto; multiple six-degree-of-freedom parallel adjustment mechanisms 7 work together to comprehensively coordinate the attitude of the fairing 8; and multiple torsion correctors 2 distributed along the adjustment holes of the fairing 8 assist in precise alignment of the fairing 8, thereby improving work efficiency.

[0029] The fairing 8 of this application adopts a semi-automatic mode for mating, which is simple to operate, has a large adjustment range, controls the support frame to the mating position, coordinates high-quality productivity, improves docking efficiency, greatly reduces labor costs, and, with the help of mechanism coordination, achieves high docking accuracy, perfectly realizing the external encapsulation of internal products.
