Abstract
A three-freedom-degree parallel-serial stacking mechanical arm with a large working space comprises a rack, a rotary table, a large arm, a small arm, a flange, a first movable sliding platform, a second movable sliding platform, a first connecting rod, a second connecting rod and a linear driver. A two-freedom-degree parallel mechanism is formed by connecting the rack, the rotary table, the large arm, the first movable sliding platform, the second movable sliding platform, the first connecting rod and the second connecting rod. The flange and the small arm are connected to the large arm in series and driven through the linear driver connected to the large arm to move. The three-freedom-degree parallel-serial stacking mechanical arm is simple in structure, light in mechanism moving mass, good in rigidity, small in inertia and good in kinetics performance, and compared with similar products, the three-freedom-degree parallel-serial stacking mechanical arm has the advantage of being high in load capacity.
Description
Technical field
The utility model relates to industrial robot field, particularly a kind of Three-freedom-degree hybrid palletizing mechanical arm with large working space.
Background technology
Robot palletizer is widely used in the middle of the automatic transporting operation of lathe loading and unloading, stamping machine automatic production line, automatic assembly line, carrying piling, container etc.Existing robot palletizer mainly contains the structure types such as cartesian co-ordinate type, circular cylindrical coordinate type and joint type.Wherein joint type robot palletizer, because of its mechanism's compactness, flexible movements, the advantage such as floor space is little, working space is large, progressively becomes the topmost version of robot palletizer.But the drive motors of the robot palletizer of this quasi-tradition fisher's formula cascaded structure all needs to be arranged on joint, cause that robot arm weight is large, the problem such as poor rigidity, inertia are large, joint error accumulation, mechanism dynamic poor-performing, is difficult to meet the requirement of high-speed overload carrying piling.Parallel institution be a kind of moving platform with fixed platform by least two independently kinematic chain be connected, have two or more frees degree, and a mechanism driving with parallel way.There is the advantages such as precision is high, compact conformation, rigidity is high, bearing capacity is strong because of it, cause lot of domestic and foreign experts and scholars' concern, correlative study has obtained great successes, has obtained good application at aspects such as motion simulator, parallel machine, micro-manipulating robots.But parallel institution also exists the shortcoming that working space is little, be therefore difficult to meet the demand of actual piling.The utility model adopts hybrid connected structure to realize the motion of robot piling, can solve traditional open-chain structure deviation accumulation greatly, poor rigidity and the little problem of parallel institution working space.
Summary of the invention
