Design of clamp and positioner of arc welding robot flexible workstation for sliding doors

After the domestic manual welding AlMgSi alloy frames of sliding doors are researched,an arc welding robot flexible workstation for frames of sliding doors is studied on the basis of Motoman UP6 robot noumenon and its subsidiary devices.Aimed at the characteristic of various specifications and models of the sliding doors manufactured by Najing Kangni Mechatronic New Limited Company,the flexible welding clamp and positioner are designed.The flexible welding clamp can be used for many specifications and models of frames,which accounts for 80 percent of the sliding doors output.This workstation can improve the utilization ratio of the equipments,reduce the buffer storage of the parts in the course of manufacture,and rapidly respond to request of the client.After the forces of the positioner are analyzed,it is known that the flexibility distortion of its worktable can not be ignored.Additionally,the frames made up of many battens produce accumulative error of manufacture and installation.As a result,an intermittent robot vision tracking system with normal lamp-house for arc welding seam is produced,which ensures that the arc welding robot flexible workstation for frames of the sliding doors can work economically and efficiently.
