Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a manipulator for producing automobile pillars. Background Art

[0002] The car pillars are vertical or nearly vertical support structures in the window or cabin area, and are mainly divided into A, B, C pillars, and D pillars in some large cars. These pillars not only support the body of the car;

[0003] The automobile pillars are formed by integrally stamping metal sheets, and when the metal sheets are stamped, a mechanical claw equipped with a suction cup structure is used to pick up and place the metal sheets. By quickly and accurately moving and placing the pillar materials, the suction cup manipulator can significantly improve the overall efficiency of the production line, which not only reduces the time and cost of manual operation, but also reduces the risk of operational errors. However, the installation position and height of the suction cup at the end of the existing mechanical claw are usually for automobile pillars of specific shapes and sizes. Therefore, after the production mold is replaced, the suction cup may not be able to form a good seal for pillars of different shapes, resulting in insufficient adsorption force. Therefore, it is necessary to adjust the installation position and height of the suction cup, but the existing suction cup structure often lacks sufficient adjustment and adaptability, and cannot be flexibly adjusted according to the specific shape of the pillar.

Through the arrangement of the first L-shaped connecting plate 11 and the second L-shaped connecting plate 12, the movement of the movable plate 9 can be achieved in cooperation with the motor 16 and the adjusting shaft 26.

[0026] It should be noted that the utility model is a manipulator for automobile pillar production. When the stamped automobile pillar is taken out from the mold, the position of the mounting beam 7 can be adjusted through the shaft seat 2, the upper arm 3, the lower arm 4, the connecting seat 5 and the suction cup frame 6, so that the multiple suction cups 10 at the lower ends of the two mounting beams 7 are in contact with the outer surface of the stamped automobile pillar, and the suction cups 10 in contact with the high surface of the pillar push the telescopic tube 21 up in the movable plate 9 and compress the compression spring 23. At this time, the connecting seat 5 continues to drive the mounting beam 7 downward through the suction cup frame 6, so that the other telescopic tubes 21 drive the corresponding suction cups 10 to contact the bottom surface of the pillar, and then, negative pressure is generated through external equipment, so that the multiple suction cups 10 are stably adsorbed on the surface of the pillar, so that it is convenient to adapt to the pillars of different shapes for material taking;

Therefore, the left-handed thread and the right-handed thread areas at both ends of the adjusting shaft 26 rotate in the screw seat 25 on the side of the corresponding second L-shaped connecting plate 12 respectively, so that the two second L-shaped connecting plates 12 move relative to each other or move oppositely at the lower end of the mounting beam 7 respectively. At the same time, the two second L-shaped connecting plates 12 use the third fixed axis 19 at the lower end to push the corresponding second connecting rod 14 to move and change the angle. Therefore, the second connecting rod 14 at the lower end of the second L-shaped connecting plate 12 synchronously pushes and rotates the first connecting rod 13 at the lower end of the corresponding first L-shaped connecting plate 11, and the other end of the first connecting rod 13 causes the first connecting rod 13 at the lower end of the fixed plate 8 to change the angle, so that the spacing between the first L-shaped connecting plate 11 and the second L-shaped connecting plate 12, and the spacing between the first L-shaped connecting plate 11 and the fixed plate 8 can be adjusted at equal intervals. Thereby, the position of the suction cup 10 can be quickly adjusted according to different automobile pillars.
