Description
Technical field
The utility model relates to robotics, particularly relates to a kind of flexible six-joint robot.
Background technology
Along with the popularization and application of industrial automation, robot widely uses.Wherein, six-joint robot with it comparatively flexibly, the advantage of highly versatile and occupy sizable ratio.Each axle needs a servomotor to drive.The most beneath also have a heavy motor.Drive feathering axis.Come to six motors, drive six axles to rotate.More up motor is less, and that spindle motor of top is minimum.But although six-joint robot structurally has certain similar part, six-joint robot quite a lot also exists that responsiveness is slow, action transmission and setting accuracy is poor, noise is larger defect.And, most of long-armed humanoid robot all needs other bascule on the market, reductor deflection armed lever middle-end on armed lever, the series of problems such as the structural volume of self is also relatively bigger than normal, and the installation difficulty that so just can produce protector increases, robot production cost is higher.
CN 203752149 U discloses a kind of six-joint robot, it is by the model of each decelerator of reasonable disposition, and adopt AC servomotor, the responsiveness of this six-joint robot is greatly improved, and improves the levels of precision of action to a certain extent.Simultaneously, by adopting the mode of belt transmission and bevel gear pair at the power resources place of comparatively crucial J6 axle pedestal, J6 axle wrist, J5 axle link arm, J4 axle horn, further increase the action of this six-joint robot, the accuracy of location, and be the inner chamber that J5 axle link arm arranges sealing, lubricating fluid is full of in this inner chamber, make the noise of this six-joint robot minimum, be provided with high versatility.
Although above-mentioned six-joint robot highly versatile, setting accuracy is high, but well-known, there is certain altitude in robot, and the weight of its first half is larger, for base and first order rotating shaft, the shearing force of bearing is maximum, is operationally the easiest broken parts, and this patent first order rotating shaft controls only by servomotor, it is less that it bears shearing force, easily causes damage.
The light-duty six axle all-purpose robots of CN 103029123 A, axle bed is fixed on arm axle, axle bed is fixed with axle bed guard box, and Three-axis drive motor, the 4th axis drive motor, the 5th axis drive motor and the 6th axis drive motor are placed in axle bed guard box; Forearm rod shell and forearm extension bar housing are separately fixed at the front and rear part of forearm decelerator, 6th axle sleeve is in the 5th axle, 5th axle sleeve is in the 4th axle, in 4th axle, sleeve is in forearm rod shell, forearm decelerator and forearm extension bar housing, 4th axle, the 5th axle and the 6th axle are fixed with respectively the 4th axle driven gear, the 5th axle driven gear and the 6th axle driven gear, the length of forearm rod shell is less than 100mm.It efficiently reduces the torque load needed for own wt, and it is without the need to traditional balance cylinder device, also can meet the balance of swing arm during work, simplify machine construction.Tight protective cover, more serves effective protective action of motor.
Although above-mentioned six-joint robot improves the power of the servomotor in first order rotating shaft, effectively ensure that the rotatory force that first order rotating shaft is enough, larger shearing force can be born, but need the base designs larger of robot, add the cost of robot, and volume is huger, take up room comparatively large, be suitable for place and the scope of application limited.
