Abstract

The invention discloses a two-degree-of-motion connection rod mechanism maniacal arm for carrying operation. The two-degree-of-motion connection rod mechanism maniacal arm comprises a pedestal 1, a first driving rod 3, a first connection piece 5, a first connection rod 19, a large arm 16, a second connection piece 7, a wrist connection rod 9, a vacuum suction disk 22, a wrist 21, a drive device, a second driving rod 13 and a second connection rod 11, wherein one end of the first driving rod 3 is connected with the pedestal 1 through a first rotating pair 2; one end of the second driving rod 13 is connected with the pedestal 1 through a ninth rotating pair 14, and the other end of the second driving rod 13 is connected with the second connection rod 11 through a tenth rotating pair 12; the second connection rod 11 is connected with the wrist connection rod 9 through an eleventh rotating pair 10; and the drive device consists of a first servo motor and a second servo motor which are respectively connected with the first driving rod 3 and the second driving rod 13 to drive the first driving rod 3 and the second driving rod 13. The two-degree-of-motion connection rod mechanism maniacal arm overcomes the shortcomings that a hydraulic system element of a hydraulic type carrying mechanical arm is high in requirement for precision, complicated in structure, prone to spill, low in reliability, low in transmission efficiency and the like.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mechanical arm of a two-degree-of-movement link mechanism used for carrying operations. Background technique [0002] At present, most of the general-purpose handling manipulators in the manufacturing industry are joint-type motor-driven manipulators with a series structure in the form of an open chain. various actions. Since the driving motors of the joint-type manipulators with series structure in the form of open chain are installed at the joints, this structure has the following problems: the manipulator arm needs to carry the weight of the motor and meet the rigidity requirements, and the cross-sectional size of the arm needs to be made larger. This will increase the load on the drive motor, increase the moment of inertia of the arm, and lead to a decrease in the dynamic performance of the manipulator. At the same time, the drive motors are installed at the joint position, result...
