Description

Technical Field

[0001] The utility model relates to the technical field of profile processing equipment, in particular to a robot FDS workstation. Background Art

[0002] With the widespread application of aluminum alloy materials in car bodies, the proportion of aluminum alloy profiles and castings continues to increase. For the connection of tubular closed structures such as plates and profiles, the SPR and spot welding bilateral connection processes can no longer meet the requirements. The currently widely used unilateral connection method is FDS (flow drill screw process). The "flow drill screw" process refers to a process in which the connecting parts are softened by high-speed rotation, and then self-tapped and tightened. The parent material at the center hole is extruded and forms an annular sleeve at the bottom of the lower plate, and finally a threaded connection is formed between the plate and the screw. This process can achieve unilateral connection with relatively small deformation and is a detachable fastening method.

[0003] When existing flow drill screw process equipment is threading two plates, it is difficult to accurately adjust the position of the screw drilled into the side wall of the plate. There is a deviation between the screw connection position and the predetermined connection position. In view of this, we propose a robot FDS workstation. Summary of the invention

[0008] As a further improvement of the present technical solution, the movable splint and the fixed splint are both L-shaped plates. When the movable splint and the fixed splint clamp and fix the plate, the lower surface of the plate abuts against the upper surface of the horizontal section of the movable splint and the fixed splint, and a certain gap is retained between the lower surface of the plate and the upper surface of the base plate.

[0009] As a further improvement of the present technical solution, the lateral displacement assembly and the longitudinal displacement assembly both include two positioning plates fixed on the upper surface of the right-angle plate, a screw rod is rotatably connected between the two positioning plates, a second motor is fixed on the side wall of one of the positioning plates, and the output shaft of the second motor is transmission-connected to the screw rod, a nut is threadedly connected to the circumferential outer wall of the screw rod, and the guide rod and the sleeve frame are respectively fixed to the two nut side walls.
