Description

A kind of two mobility linkage spot welding manipulators
Technical field
The present invention relates to machinery field, particularly a kind of two mobility linkage spot welding manipulators.
Background technology
Most of currently manufactured general mash welder tool hand of industry is the cascaded structure joint type motor driving machine for open form Tool hand is mainly characterized in that driving motor all on each joint of manipulator, drives manipulator each by motor The various actions of manipulator are realized in the rotation in a joint.Due to the driving electricity of the cascaded structure articulated robot of open form Machine is all mounted on the position in joint, and this frame mode has the following problems:Manipulator arm needs the weight of carrying motor simultaneously Rigidity requirement need to be met, arm sectional dimension needs to be made larger, can so increase the load of driving motor, increase the fortune of arm Dynamic inertia, causes manipulator dynamic property to decline, while driving motor all causes the accumulation of manipulator to miss mounted on joint position Difference is big, bearing capacity is small, complicated, the degree of modularity is low.It is in parallel with the development of motor technology and the raising of control technology Mechanism provides extensive development space for manipulator, by motor-driven multiple freedom parallel mechanism is controlled not only to have work Space is big, flexible movements, can complete complicated movement locus output, while also has and manufacture at low cost, maintaining is simple etc. Advantage.
The content of the invention
It is an object of the invention to provide a kind of two mobility linkage spot welding manipulators, so as to overcome Serial manipulator Accumulated error is big, and precision is relatively low;Rigidity is low, bearing capacity it is small the shortcomings that.To achieve the above object, technology provided by the invention Scheme is:A kind of two mobility linkage spot welding manipulators, including pedestal 1, the first driving lever 3, the first connector 5, first Connecting rod 19, large arm 16, the second connector 7, wrist connecting rod 9, welding gun 22, wrist 21, driving device, the second driving lever 13, second Connecting rod 11;Described first driving lever, 3 one end is connected by the first revolute pair 2 with pedestal 1, the other end by the second revolute pair 4 with First connector 5 connects, and the first connector 5 is connected by the 3rd revolute pair 17 with first connecting rod 19, and first connecting rod 19 passes through Four revolute pairs 18 are connected with large arm 16, and large arm 16 is connected by the 5th revolute pair 15 with pedestal 1, described second connector, 7 one end It is connected by the 6th revolute pair 20 with large arm 16, the other end is connected by the 7th revolute pair 8 with wrist connecting rod 9, and described second connects Fitting 7 is connected by the 8th revolute pair 6 with the first connector 5;Described second driving lever, 13 one end by the 9th revolute pair 14 with Pedestal 1 connects, and the other end is connected by the tenth revolute pair 12 with second connecting rod 11, and second connecting rod 11 passes through the 11st revolute pair 10 It is connected with wrist connecting rod 9;Driving device is made of the first servomotor, the second servomotor, respectively with the first driving lever 3, Two driving levers 13 are connected, and the first driving lever 3, the second driving lever 13 are driven.
The controllable more bar closed chain mechanisms of two mobility linkage spot welding machinery hand gettings of one kind of the invention, with open-chain structure phase Than improving the stationarity and reliability of arm operation, no accumulated error, precision is higher;Compact-sized, rigidity is high, carries energy Power is big, inertia is low, dynamic property is good, arm motion track flexible and diverse.Overcome fluid pressure type spot welding manipulator hydraulic system The shortcomings such as high, the complicated, easy oil leakage of components accuracy requirement, poor reliability, transmission efficiency be low.
