Truss robot grabbing device

The invention belongs to the technical field of truss robots, and particularly relates to a truss robot grabbing device. The grabbing device comprises a common gripper and a quick-change gripper. Thequick-change gripper comprises a C-shaped quick-change gripper, a sling type quick-change gripper and an opening-closing type quick-change gripper. The common gripper is used for grabbing common sandcores. The quick-change gripper is used for grabbing special sand cores which cannot be grabbed by the common gripper. In order to overcome the defects in the prior art, the truss robot grabbing device is provided. The three quick-change gripper structures can effectively grab the sand cores of various different structures, and the proper quick-change gripper is flexibly adopted according to the structures of the sand cores. Thus, the grabbing device can automatically grab the sand cores of any structure, the problems that an existing truss robot cannot grab thin sand cores and the sand coresare placed in a short dista
