Technical field
The present invention relates to mechanical engineering fields, in particular to a kind of to be filled using Three Degree Of Freedom multi-connecting-rod mechanism blanking mechanical It sets.
Background technique
Most of currently manufactured general oxygen-acetylene cutting manipulator of industry is driven for the cascaded structure joint type motor of open form Dynamic manipulator, is mainly characterized in that driving motor is all mounted on each joint of manipulator, is driven by motor mechanical The various movements of manipulator are realized in the rotation in each joint of hand.Due to the drive of the cascaded structure articulated robot of open form Dynamic motor is all mounted on the position in joint, and this frame mode has the following problems: manipulator arm needs to carry the weight of motor It measures and rigidity requirement need to be met, arm sectional dimension needs to be made larger, will increase the load of driving motor in this way, increases hand The movement inertia of arm causes manipulator dynamic property to decline, while driving motor is all mounted on joint position and causes manipulator Accumulated error is big, bearing capacity is small, structure is complicated, the degree of modularity is low.With the development of motor technology and mentioning for control technology Height, parallel institution provide extensive development space for manipulator, by controlling motor-driven multiple freedom parallel mechanism not Only big, flexible movements, the motion profile output of achievable complexity with working space, while the also low, maintenance with manufacturing cost Maintain the advantages that simple.
Summary of the invention
Three Degree Of Freedom multi-connecting-rod mechanism blanking mechanical device is used the purpose of the present invention is to provide a kind of, to overcome Serial manipulator accumulated error is big, and precision is lower;Rigidity is low, bearing capacity it is small the shortcomings that.To achieve the above object, this hair The technical solution of bright offer is: a kind of to use Three Degree Of Freedom multi-connecting-rod mechanism blanking mechanical device, comprising: pedestal 1 can be rotated Platform 13, telescoping mechanism, elevating mechanism, luffing mechanism and rotatable wrist 11, burning torch 10 and driving device.Telescoping mechanism It include: the first driving lever 2, second connecting rod 4 and the first large arm 8;One end of first driving lever 2 is articulated with rotatable platform 13 On, one end of second connecting rod 4 and the other end of the first driving lever 2 are hinged, and one end of the first large arm 8 is another with second connecting rod 4 End is hinged.Elevating mechanism includes the second driving lever 3, third connecting rod 5 and the second large arm 13;It cuts with scissors one end of second driving lever 3 It is connected in rotatable platform 13, one end of third connecting rod 5 and the other end of the second driving lever 3 are hinged, one end of the second large arm 13 It is hinged with the other end of third connecting rod 5;Luffing mechanism includes: third driving lever 12 and pitch lever 6;Third driving lever 12 One end is articulated in rotatable platform 13, and one end of pitch lever 6 and the other end of third driving lever 12 are hinged, the pitch lever 6 Middle part and the middle part of the second large arm 13 are hinged, and the other end of pitch lever 6 is articulated with the middle part of the first large arm 8;Rotatable wrist connects The top of bar 11 and the other end of the first large arm 8 are hinged, and lower part and the other end of the second large arm 13 are hinged.Driving device is three A servo motor is connect with the first driving lever 2, the second driving lever 3 and third driving lever 12 respectively, respectively actively to first Bar 2, the second driving lever 3 and third driving lever 12 are driven.
The present invention is mounted on rotatable platform using controllable more bar parallel institutions, whole driving motors to driving lever It is driven, compared with Serial manipulator, reduces the movement inertia of arm, improve manipulator dynamic property, improve machine Tool hand traveling comfort and reliability, no accumulated error is compact-sized, and rigidity is high, and large carrying capacity, inertia is low, dynamic It can good, Robotic Manipulator Motion Trajectory flexible and diverse.
