The invention discloses a servo electric multi-petal grab bucket which comprises a lower support, an upper support and a servo electric cylinder, a plurality of claws are hinged to the lower support and arranged in the circumferential direction of the lower support, the upper support is arranged above the lower support, a curved bar is arranged between the upper support and the claws, and the curved bar is connected with the servo electric cylinder. One end of the curved bar is hinged to the upper supporting foot, the other end of the curved bar is hinged to the claw petal, the servo electric cylinder is arranged between the lower support and the upper support and fixedly installed on the lower support, and the output end of the servo electric cylinder is in transmission connection with the upper support and used for driving the lower support to ascend and descend. And the plurality of claw petals are opened and closed. The grab bucket is driven by the servo electric cylinder to be opened and closed, so that the grabbing stability and precision of the grab bucket are greatly improved, and the later debugging cost and maintenance cost are reduced.

    本发明公开一种伺服电动多瓣抓斗,包括下支架、上支架和伺服电动缸,所述下支架铰接有若干爪瓣,若干所述爪瓣沿所述下支架的周向设置,所述上支架设于所述下支架的上方,所述上支架与所述爪瓣之间设有曲杆,所述曲杆的一端与所述上支脚铰接、另一端与所述爪瓣铰接,所述伺服电动缸设于所述下支架与所述上支架之间,并固定安装在所述下支架上,且所述伺服电动缸的输出端与所述上支架传动连接,用于驱使所述下支架升降,以使若干所述爪瓣开合。本发明通过伺服电动缸驱动抓斗开合,不仅大大的提高抓斗的抓取稳定性和精准度,而且降低了后期调试成本和维护成本。
