[0002] When performing automated spray repair on rotating shell workpieces, such as aircraft radomes, due to the large size, heavy weight and insufficient stability of the rotating shell workpiece, the robot must be equipped with a positioner to perform vertical rotary spraying. Considering that the rotating shell workpiece is too high, only horizontal transfer and vertical spraying can be selected. Considering that the workpiece cannot be manually moved after flipping, the rotating shell workpiece needs to be quickly and stably docked with the positioner after flipping.

[0003] An existing shell flipping device consists of a base, a screw transmission unit, a lifting unit, a rotation unit, and a control system. The screw drive motor drives the screw to rotate forward and reverse, driving the screw mounting seat to slide on the base, thereby causing the two vertical support seats to move relative to or in opposite directions along the X-axis on the base, thereby achieving axial clamping and loosening of the special-shaped shell. The lifting drive motor drives the screw passing through the interior of the slider, driving the slider to slide up and down along the vertical slide rail on the vertical support seat, thereby adjusting the height of the slider and the rotation unit on the slider on the vertical support seat. The rotation drive motor drives the driving gear to rotate, and at the same time drives the driven gear meshing with the driving gear to rotate, thereby transmitting the driving force to the three-claw support assembly to achieve support and rotation of the shell.

The reducer input shaft 20 is connected to the first power element.

[0022] When the rotating housing workpiece 23 needs to be moved horizontally, power is input through the first power member, which drives the adjustment screw 7 through the reducer input shaft 20, the sprocket mechanism reducer 21, and the sprocket box 22. The adjustment screw 7 rotates, moving the screw fixing seat 8 and the flange 2, thereby completing the movement of the rotating housing workpiece 23. During this movement, the slider 5 supports the rotating housing workpiece 23 to prevent deflection.

[0023] Preferably, the flip unit includes a movable flap 9, auxiliary support rods 12, a rotating support rod 11, a movable push rod 13, and a push rod seat 19. The movable flap 9 is a rectangular structure, with the top of the movable flap 9 connected to the screw fixing seat 8 and the slide rail 6. The auxiliary support rods 12 are arranged on the rotary positioner turntable 17. There are two sets of auxiliary support rods 12, which are arranged diagonally along both sides of the movable flap 9. The auxiliary support rods 12 are normally arranged horizontally. The top of the auxiliary support rods 12 is equipped with a quick clamp 10, and the end is equipped with an auxiliary support base 16 connected to the rotary positioner turntable 17. There are two sets of rotating support rods 11, which are arranged on one side of the movable flap 9.

The movable flap 9 can be flipped up and down along the two sets of rotating support rods 11.

[0024] The movable push rod 13 and push rod seat 19 are located on the side of the movable flap 9 away from the rotating support rod 11. The movable push rod 13 is tilted, and the lower end of the movable push rod 13 is hinged to the rotary positioner turntable 17, and the upper end is hinged to the push rod seat 19.

The base is fixed to the rotary positioner turntable 17, the articulated rod is hingedly connected to the base and fixedly connected to the auxiliary support rod 12, and the adjustment bolt is coaxially threadedly connected to the articulated rod. By loosening the adjustment bolt, the auxiliary support rod 12 can be flipped from a horizontal to a vertical position. Then, by tightening the adjustment bolt, the quick clamp 10 on the side wall of the auxiliary support rod 12 can clamp and support the movable flap 9. After spraying is completed, the auxiliary support rod 12 is flipped back to a horizontal position by adjusting the bolt, ready for the next spraying.

[0029] Preferably, a right-angle seat 4 is provided on the side wall of the movable flap 9. The right-angle seat 4 is detachably connected to the frame of the tooling device for the rotating shell workpiece 23, thereby enabling the movable flap 9 to be fixed at a specified angle. Specifically, the right-angle seat 4 has a double-ear structure and is connected to the frame of the tooling device for the rotating shell workpiece 23 via a quick-release pin.

The user drives the movable push rod 13 by driving the push rod input shaft 14 of the movable push rod 13, thereby driving the movable flap 9 to flip. When one side of the movable flap 9 flips to abut against the rotary positioner turntable 17, the rotary shell workpiece 23 is flipped from the horizontal position to the vertical position.

[0031] After the posture is fixed, the reducer input shaft 20 is first driven by the first power element, and the sprocket mechanism reducer 21 is used to drive the sprocket mechanism in the sprocket box 22, driving the adjusting screw 7 to rotate, and then driving the slider 5 to move on the slide rail 6, and finally the position change of the rotating shell workpiece 23 can be achieved, and then the rotating shell workpiece 23 and the rotary positioner turntable 17 can be safely determined to have the same rotation axis position, ensuring the accuracy during the automated spraying process; then the user puts the auxiliary support rod 12 to a vertical state, opens the quick clamp 10, and enables it to clamp and support the movable flap 9.

[0032] After the automated spraying work is completed, the frame part of the rotary shell workpiece 23 tooling device is pushed back, the quick clamp 10 is closed, the auxiliary support rod 12 is placed in a horizontal state, and then the push rod input shaft 14 of the movable push rod 13 is driven, so that the rotary shell workpiece 23 can be flipped from a vertical position to a horizontal position, and the right-angle seat 4 is fastened to the frame part with a quick-release pin; finally, the connection between the push rod seat 19 and the push rod is removed, and the connection between the rotating support rod 11 and the rotating support base 15 is removed, and the flipping process is completed.

[0033] To sum up, the present application sets a translation unit and a flipping unit that can cooperate with each other, sets the rotating shell workpiece on the translation unit, and can stably adjust the position and posture of the rotating shell workpiece through the translation unit and the flipping unit, thereby solving the problems of the existing rotating shell workpiece positioning mechanism not being able to adjust the posture of the rotating shell workpiece and making the rotating shell workpiece movable on the positioner during use, and the problem that it may cause certain inconvenience to the user.
