The invention provides a multi-degree-of-freedom automatic accompanying trolley, which includes a control box body, a load-bearing bracket is set on the outer edge of the control box, and the connecting arms on the load-bearing bracket are suspended on the I-shaped guide rails on both sides of the trolley through a horizontal driving device , which is characterized in that: the control box is connected with an auxiliary rotating mechanism through a vertical driving device to form a rotating pair. The auxiliary rotating mechanism includes a supporting frame, a rotating driving motor, and a friction driving wheel connected with the rotating driving motor; an inverted U-shaped spreader is hung on the supporting frame, and the arc track above the inverted U-shaped spreader is in contact with the friction driven wheel. The trolley provided by the present invention has four degrees of freedom: moving horizontally and vertically, rotating around the vertical direction (z-axis) and rotating around the horizontal direction (x-axis) of the inverted U-shaped spreader, which increases the flexibility of the transportation and assembly process It improves the efficiency of assembly and the level of automation, and reduces the burden on workers.
Description
technical field [0001] The invention relates to the technical field of automatic transportation, in particular to a multi-degree-of-freedom automatic accompanying trolley. Background technique [0002] The automatic accompanying trolley is a kind of automatic material conveying device, which belongs to the field of automatic conveying technology. It is widely used in automatic conveying production lines such as machinery manufacturing, automobile assembly, and component assembly. It is used in various degrees in large and medium-sized enterprises at home and abroad. The automatic accompanying trolley can be automatically controlled according to the operation instructions according to the requirements of the station. Its main features are high conveying efficiency, low failure rate, low noise, convenient equipment maintenance, and high level of automation. For automobile conveying lines, it can realize multi-vehicle mixed line production. A typical self-propelled trolley con...
